How to determine if two cones with vertices at origin, intersect?

Accepted Answer by Sven
Suppose I have two different sets of data points in 3d, that each are in a different tilted plane (different theta,phi,r of normal). I manage to find the enclosing circle for each of these sets of points (center and radius). Now imagine a solid angle (cone) with the vertex at origin and base at the enclosing circle. So I have two cones that have different heights, and their middle axis is at a different theta and phi. Now how can I figure out if these cones have any overlap (intersection) or not? And also if they are not overlapping how close are they, this is rather complicated to define and I still haven't figured out a suitable proximity measure. But maybe you guys out there have some ideas?

EDIT: discard this comment; I wrote it before realizing that your cones have both their tip at the origin.
You will probably find a lib. that does it, but if you had to do it "by hand".. you could start by computing the distance between the axes of both cones. This is done by computing the scalar product between a vector made of two arbitrary points from the two axes respectively and a unit vector orthogonal to the two axes. You get the latter by normalizing the cross product between two arbitrary directional vectors defining the two axes.
It would not be too complicated then to find radii of both solid angles at closest locations between the two axes. However, what you call "overlapping" is vague. If the two cones have an intersect, its geometry will be quite complicated.
No products are associated with this question.

Hi again Doc,
First thing you can do is check the dot product between the normal vectors of both cones' planes. If the dot product is less than zero, the cones cannot intersect. If the dot product is one, then the cones must intersect.
An easier way to think about "nice" 3D shapes (like cones) is to ask if it can project to 2D. In this case, happily the problem can be reduced to 2D.
You've got two "plane normal vectors" that intersect at the origin. This means they are co-planar. If you find this plane (which is straight forward with a couple of cross products), then project the outline of the cones onto this plane, you've reduced the problem down to a question of "does triangle A intersect triangle B".
Or, more simply:
 - Get the "apex angle" of each cone/triangle from its normal vector
 - Get the angle subtended between the normals of each plane
 - If the sum of the apex angles is greater than this subtended angle, your cones/triangles intersect.
So, let's say you know a few things:
1. The unit vectors of each plane's normal vector:
zVec1 = rand(1,3); zVec1 = zVec1/norm(zVec1)
zVec2 = rand(1,3); zVec2 = zVec2/norm(zVec2)
2. The "height" of each triangle (ie, the distance from your cone plane to the global origin:
ht1 = 10
ht2 = 7
3. The "width" of each triangle (ie, the radius of each cone):
wdth1 = 2
wdth2 = 3
Now you've got all you need to calculate the apex angle of each cone (ie, between the cone wall and the normal vector):
ang1 = atand(wdth1/ht1)
ang2 = atand(wdth2/ht2)
And the angle between the two plane normal vectors:
twoVecDotProd = dot(zVec1,zVec2)
angBetweenNormVecs = acosd(twoVecDotProd)
Now you've got your result:
conesIntersect = twoVecDotProd>0 && ang1+ang2 >= angBetweenNormVecs
Does that work for you?

Hi Sven, thanks again for your valuable help.
This method is a very smart solution to my problem. But I have tried it on some random samples and it seems it does not perform correctly. BTW I have two questions about it: first, when you say "width of each triangle (ie, the radius of each cone)", do you basically mean the diameter of the circles I have as the base of the cones? Cause later you divide it by 2, in order to find the apex angle.
Also, I am a bit confused why you chose the inequality so that there is an intersection when ang1+ang2 is larger than angBetweenNormVecs, I would have assumed the opposite. Needless to say, I tried the opposite too and in some random runs it yields a wrong answer.
on 7 Feb 2013
Oh, sorry, yes, I meant "diameter". I've updated the solution above to use the word "radius" and to not divide this by two.
on 7 Feb 2013
Think of it this way, when angBetweenNormVecs is very small, the cones are pointing in the same direction and are more likely to intersect. When the ang1 or ang2 of the cones gets larger, that means that the cones are covering more space, and are similarly more likely to intersect. The greater-than sign is pointing the right way, and I'm quite confident that the above algorithm works correctly.
Anyway, it will always be better to show a specific example (with code to set up your zVecs/hts/wdths) rather than say that random samples don't work...
Thanks, Sven.

Can English Muffins Be Frozen?
Maria Foster
Last Updated on
by Maria Foster
Can you freeze English muffins if you can't eat them right away? Yes, but the way you store them will affect how they taste after you reheat them.
English muffins
How To Freeze English Muffins
While you can throw an entire unopened package of English muffins straight into the freezer, this isn't as effective as storing them properly.
Here's how to do that:
The first step is pre-slicing the English muffins. Use a fork for this instead of a knife. Pulling them apart with a fork helps retain their internal structure, where the air bubbles are good for cupping honey, jam, or other fillings. This works similarly to waffles. Separating English muffins this way makes it easier to reheat them later and will not lower their quality.
Next, wrap each set of halves separately. Many people use aluminum foil for bread, but you can also use plastic wrap or similar storage material. The goal here is to minimize the air that flows over the product, which will ultimately lead to damage and freezer burn.
Pick a Proper Container
After that, find a proper freezer bag. If you bought the muffins from a store, the plastic wrapping them is usually too thin to work correctly in a freezer. It's better to use a resealable plastic bag designed for freezers because it's thicker and much less likely to get damaged over time.
If you're using a bag, squeeze out as much air as you can before sealing the bag. This will reduce the amount of freezer burn your food experiences.
Alternatively, you can store your English muffins in a large, sealed container. Some people use a large plastic container to rotate bread through as needed, which provides even more protection. However, it also wastes some space in the freezer, so it's not a good choice for every family.
Finally, decide where you want to store your muffins. The best place is in the coldest part of the freezer, which is always somewhere in the back and usually lower in the freezer. The temperature is closest to constant there, which helps prevent freezer burn. Things near the front are more likely to experience changes.
You can put your English muffins closer to the front if you're using a thick plastic container. These containers don't change their temperature quickly enough when you open the door to hurt your food, so they provide added flexibility in storing food while maintaining quality.
Finally, regardless of where you store your English muffins, try to keep them away from anything with a strong odor. They might adopt those smells as part of their flavor, which can ruin the experience of eating them.
How Long Do English Muffins Last In The Freezer?
English muffins maintain most of their quality for three months. However, this is only true if you're storing them unheated and by themselves. If you're assembling meals out of them, such as freezing breakfast sandwiches, their lifespan is determined by the other ingredients in that meal and could range from a few days to a few weeks.
Can you freeze English muffins any longer than three months, you ask? Yes, you can.
While you should eat them within three months for the best quality, they'll last for up to six months if you need to keep them any longer. Past this point, they're likely to start suffering damage even if you stored them well.
Everything eventually dehydrates and experiences freezer burn, so make sure you have a plan to use the muffins and try to eat the oldest ones first.
What Is The Best Way To Store English Muffins?
As bread products, English muffins thaw considerably better than some other foods. You can use a toaster, an oven, or even your countertop (for a slower thaw) if needed
Storing them this way means you don't have to half-defrost them to separate them later, which makes them considerably easier to use.
For more information on storing English muffins and other types of food, make sure you familiarize yourself with the USDA guidelines.
How To Thaw English Muffins
For faster results, start by heating them for 20-30 seconds in your microwave. The time you'll need depends on the power of your microwave, so experiment a little and figure out what works best for you.
Optionally, you can put a paper towel around the muffins while you're microwaving them. This will help keep their remaining moisture in and stop them from drying out too much while you're reheating them.
You don't need to completely thaw them here. In fact, it's okay even if part of the muffin still feels cold and frozen. The goal of using a microwave this way is softening the muffins up a little and turning them from frozen solid to a more room-temperature setting.
Once they're partially thawed this way, you can put them in a toaster or toaster oven and finish heating them. They should end up near their normal toasting temperature and taste just fine. Bread is one of the more durable products you can put in the freezer, so you may not even notice the difference as long as you eat them within a few months of freezing.
English Muffin From Microwave
Advanced Toasting
Suppose you're going to heat English muffins in a toaster oven after thawing them. In that case, you can add ingredients after microwaving them (as described above) but before putting them into the toaster.
This is a great opportunity to add wetter toppings like pesto, meats, cheeses, or anything else you want to add that can be warmed up. However, the density of your toppings makes a large difference here. If you pile things on too thickly, the heat won't get all the way to the muffin and some parts will still be cold.
To mitigate this, try to avoid having the toppings be any thicker than the muffin itself. Similarly, experiment a little with your specific toppings and with different settings on your toaster oven to see what heats the best.
In many cases, toasting a little above the halfway point works out well for English muffins. While that might be too much for them normally, the extra ingredients will absorb most of the heat and help provide a consistent temperature for the final result.

The most important thing to remember when working with open pipes (what is here referred to as a pipe is any cylindrical solid, i.e. a tube, and "open" is defined as having no obstruction at either end) is that at the two ends are anti-nodes. Thus, unlike a closed pipe, the fundamental frequency and the subsequent overtones increase by one-half of a wavelength. This concept is very hard to understand without looking at the image below.
The most simple possibility is the "fundamental frequency" where there is one node in the center of the pipe. The wavelength is 1/2 lambda (λ). The next possibility is the "first overtone". Here, there are two nodes (therefore n=2) and the wavelength is 2/2, or 1λ. Then comes the second overtone, with three nodes, which is 3/2λ.
The equation for finding the length of an open pipe is
l=length of pipe n=nodes
This equation can easily be rearranged to solve for wavelength:
Let's use this equation with a practice problem: Find the fundamental frequency of an open pipe that is.5m long.
To solve this, we need to use two equations. First, solve for lambda:
= 2(.5m)/1 = 1m
Then, use substitute the 1m for lambda in the equation
= (330m/s)/1m = 330Hz, our final answer. Great job!

Parks and Cemeteries, the section that oversees the development and maintenance of Dog Parks, is piloting the use of pedestrian traffic counters at Dog Park entrance areas. The purpose of the program is to provide baseline data on when and at what volume Dog Parks across the city are being used.
What is the data used for?
Data on volume and time of use is essential to:
- provide a snap shot of when and at what volume Dog Parks are being used;
- build long-term support for City Dog Parks;
- contribute to City processes including capital/maintenance programs, planning, design and program evaluation.
Where is the data collected?
Currently 2 pedestrian traffic counters have been installed at Nathan Cirillo and Borer's Dog Parks. Counters will be rotated to other Dog Parks over time, at which time data will be reviewed.
City of Hamilton Traffic Operations operates a similar program with over 20 counters on trails and pathways, through the Active Transportation Benchmarking program.

Not so cheap talk: a model of advice with communication costs
Hertel, Jo and Smith, John (2009): Not so cheap talk: a model of advice with communication costs.
Download (189kB) | Preview
We model a game similar to the interaction between an academic advisor and advisee. Like the classic cheap talk setup, an informed player sends information to an uninformed receiver who is to take an action which affects the payoffs of both sender and receiver. However, unlike the classic cheap talk setup, the preferences regarding the receiver's actions are identical for both sender and receiver. Additionally, the sender incurs a communication cost which is increasing in the complexity of the message sent. We characterize the resulting equilibria. Under an additional out-of-equilibrium condition (Condition L), if preferences for sender and receiver are identical then the only equilibria are the most informative, feasible ones. A similar result appears in Chen, Kartik and Sobel (2008) when their No Incentive to Separate (NITS) condition is applied to the case where communication is costless but preferences diverge. Additionally, we model the competency of the advisee by the probability that the action is selected by mistake. We show that the informativeness of the sender is decreasing in the likelihood of the mistake. When the preferences between players diverge and when there are communication costs, we are not guaranteed uniqueness and we provide an example where an increase in communication costs can improve communication.

Numerous physical and chemical changes occur in the products during the baking process. These changes may affect the migration mechanism of water and the drying behaviour of the product. In the present study temperature effects on the drying behaviour of raw thin biscuits of 7x5x0.25 cm dimensions were studied in a laboratory oven by applying constant or linearly decreasing oven temperatures between 100 and 195-degrees-C. With constant oven temperatures a falling rate drying model, and with linearly decreasing oven temperatures a constant rate drying model stimulated these processes. Final moisture contents are one of the major properties determining the shelf life of the biscuits. These models may be used as simple methods for calculating the baking times.

Are Grades 10-12 physical sciences teachers equipped to teach physics?
MetadataShow full item record
South African schools have been confronted with educational reform since the mid-nineties and the process is still continuing. The concomitant changes put a very high demand on physical sciences teachers and also have an impact on teacher behaviour. The purpose of this study was to probe whether teachers could be considered equipped to teach the physics part of the FET physical sciences curriculum. A revised framework on teacher behaviour, which includes three factors, namely teacher knowledge, teacher views and beliefs, and teacher attitudes, was used in conjunction with a questionnaire and a survey to analyse the data from individual and focus group interviews. A total of 68 FET physical sciences teachers from urban, township and rural schools participated in the research. Our findings indicate that teachers are positive about the curriculum. However, the problems identified with training, support and resources as well as the lack of teachers' subject content knowledge, particularly in rural and township schools, cannot be blamed on the curriculum and therefore cannot be fixed by curriculum changes.

Consider the Source: Why Was Maitreya Too Fat to Sit in Full Lotus?
In the great Buddhist grottos at Dunhuang, the unequalled repository of Buddhist statues and art in China's far west, certain Buddha figures do not sit in full lotus as one might expect. Nor do they stand erect, another common posture. Instead, they sit with their legs crossed at their ankles, a puzzling, rather uncomfortable looking position. The Chinese scholar Gu Zhengmei argues that this posture is a sure sign that these statues represent Maitreya Buddha, the "Buddha to Come" who is said to appear in the world when all have forgotten the dharma. He claims that it is consistent with discoveries of Maitreya images not just at Dunhuang, but also in Greek-influenced Gandhara, where the first icons of the Buddha were found.

Difference Between Fixtures and Jigs
The words fixtures and jigs are common terms used in machine shops. Although both are used as tools to mass-produce parts, they have two distinct functions.
Fixtures are used to hold work pieces in at specific location. For example when parts are machined on a machining center or wire EDM, they are clamped into a fixture which reduces the amount of set up time. This eliminates set up errors and brings down production cost. As all machine shops owners are aware of, the best machine tool is one that is making parts and not sitting idle. Fixtures need to be heavy and rigid, and machined with precision in order to have consistent results.
A jig is a tool that guides another tool in order to improve the accuracy of the part during machining. Often a jig is used in drilling, boring, and tapping operations so the drill doesn't wobble or stray away from the location where it's suppose to be. They are also used to make sure a part is drilled to a specified depth without the need constantly check and re-drill if needed.
At Precision Technologies, we specialize in the design and manufacturing of custom jigs and fixtures. Since we incorporate the latest machine tool technology and employ experienced machinist, we can ensure your jigs and fixtures will have the accuracy that will meet your expectations. We design and build the following types of fixtures and jigs: welding & assembly fixtures, checking fixtures, work holding fixtures and welding/ assembly fixtures.

8 characteristics of a good insurance executive
Your article was successfully shared with the contacts you provided.
Within the insurance industry, we take certain attributes for granted: diligence, detail orientation, a fundamental understanding of data.
However, it's rare to take a step back and examine the actual psychological characteristics of insurance executives — how they think, how they make decisions, how they approach interactions with others.
What is the psychological profile of an insurance executive — and how does this profile differ from the attributes of executives in other fields?
A recent study by Russell Reynolds Associates sought to answers these questions by analyzing the leadership and behavioral attributes of 87 insurance executives, and comparing those executives to the more than 5,000 executives across all industries in Russell Reynolds's database.
Three psychometric tests were used:
 - 16pf, which measures communication and teamwork styles.
 - OPQ-32, which examines personality related to management and leadership roles.
 - Hogan Development Survey, which identifies patterns of behavior that tend to appear when a person is stressed or under pressure.
The overall findings were striking. Insurance executives, defying stodgy industry stereotypes, score high on some quite vibrant personality traits.
The 'secret sauce'
Understanding this profile (as well as how these traits can be developed) can be of tremendous value to anyone in the insurance field.
The personality traits of insurance executives — the "secret sauce" of this group of executives — fall into three camps: possessing a concerned eye, being a steady pair of hands, and embodying dynamism.
Read on for our profile of what makes a good insurance executive.
1. They possess a concerned eye.
Insurance executives are more likely to worry before significant occasions than the average executive. This is a double-edged sword — this characteristic raises the right concerns, but can create mental drag due to the resulting anxiety.
2. They are a "steady pair of hands."
Insurance executives score higher than the overall executive population on a cluster of traits that relate to procedural and interpersonal steadiness.
3. They are more trusting and more likely to perceive others as reliable.
In our research, again and again, top executive groups score higher than the overall population for being trusting — the ability to trust others facilitates a whole host of productive, collaborative interactions.
To develop this trait, consciously reflect back on situations where you feel you withheld your trust from a business partner or group of business partners, and where that lack of trust was not ultimately validated.
What in your mind were the reasons for not trusting? How can you "rewrite the story" for future interactions toward putting your faith in others where appropriate?
4. They are emotionally even-keeled.
According to our psychometric results, insurance executives are more emotionally even than their peers in other industries — which can be a true asset in an industry facing constant disruption.
To develop this trait, seek regular feedback from colleagues about your emotional style. Are you perceived as being emotional or intense? Are these perceptions magnified when using communication channels like email?
5. They prioritize well.
With a million priorities constantly in play, it's perhaps not surprising that insurance executives are more oriented toward prioritization than their executive peers.
To develop this trait, constantly re-evaluate your priorities against your broader strategic goals. Make sure you're managing the "urgent vs. important" tradeoff correctly. And ask colleagues for feedback on your prioritization – sometimes an outside set of eyes can spot issues easily.
6. They embody dynamism.
This cluster of attributes is perhaps the most surprising — and meaningful — set of results. Insurance executives score higher for a group of dynamic traits than the average executive.
7. They are bolder and more achievement oriented.
Compared to the overall executive population, insurance executives are more likely to act with confidence and pursue ambitious goals.
To develop this trait, embrace your own convictions. Place greater trust in your inner voice — and don't hesitate to verbalize your position on an issue followed up by the proper supporting points. Vet your goals against a yardstick of scale — are they ambitious enough?
8. They seek a high level of activity.
And insurance executives can speed up their actions to match the speed of the business around them.
This is another group of traits we often see in very successful populations, broadly speaking — the ability to move fast and to embrace constant activity.
To develop this trait, constantly have your key priorities in mind, facilitating speedy but well-considered decisions. Look at areas where you feel you do not move quickly — or do not enjoy a high level of activity — and attempt to identify and correct for the unifying themes.
Your self-assessment
So what should insurance executives think about as they look at this psychological profile?
First, consider to what extent you conform to — or contrast with — the three areas of attributes described (concerned eye, steady pair of hands, dynamism). Are there aspects of your personal style that you would develop to be more closely aligned with these attributes? Why or why not?
Moreover, it's useful to think about what these attributes say about how the industry will move forward. Based on this psychological profile, how will insurance executives cope with changes like digital disruption, the rise of big data and diversity concerns?
On a personal level, consider how you can leverage your own psychological attributes to be a useful part of these changes. After all, deeper understanding of your own leadership style is interesting to reflect upon — but powerful when put into action.

Summary: In our study, we undertake a relative efficiency analysis of hospitals providing inpatient care, which play a key role in the Hungarian health care system. According to the Competitiveness Report 2020 of the Hungarian National Bank, the Hungarian health care system has a number of reserves, and the sustainability of the system can be improved by using these reserves. In the 2015-2019 period, particular attention has been paid to the identification of achievable and meaningful indicators in the sector under review. The relative effectiveness analysis (DEA) method can be used to address this challenge. The units of our analysis are state-owned institutions in Hungary, typologised by the total number of beds. General profile hospitals with a bed count between 600 and 1200 beds were included in the analysis. The results of running the programme have clearly shown that there are some institutions that do not operate as efficiently as the majority of the organisations included in the study, but further research and refinement of the indicators is needed to determine the practical application of the pilot studies.

Your best friend for file transfer.
Fetch application logoFetch
Fetch Icon Fetch Help > Using Fetch > Uploading pictures for eBay
A common use for Fetch is to upload pictures of items you're auctioning on eBay to a web server. Fetch is only part of what you need to accomplish this task—you also need an account with a service that offers web hosting, such as your Internet service provider or a web hosting service. That provider should be able to tell you the hostname, username and password you need to use in Fetch.
Fetch can only help transfer pictures from your Macintosh to a web server; it cannot host pictures for you. Fetch Softworks is not a service provider.
To upload pictures for use on eBay, follow these steps:
 1. Create a digital picture of your item. Use a digital camera, scan the item with a scanner, or take your film to a store that can put your photos on CD.
 2. Choose the New Connection command from the File menu. The New Connection dialog appears:
 1. Enter the hostname of your server, your username, and your password in the appropriate text fields of the New Connection dialog. If you are unsure what to enter here, see the What do I enter in the hostname, username, and password fields? help topic.
 2. Click the Connect button.
 3. You should see a list of the files that make up your website:
 1. A dialog for selecting files appears:
 1. Navigate to the folder on your Macintosh where the picture of your item is stored.
 2. Select it.
 3. Click the Put button to begin the transfer.
 4. Once the file is transfered, you are done using Fetch for now.
 5. Go to eBay in your web browser and fill out the form for listing your item for sale. One of the steps is to enter the web address (URL) for the picture you have just uploaded. The web address (URL) will look something like this:. The web address may be different from the hostname you used to upload the picture. Your service provider can tell you what the correct web address for your picture is. If you think you know it, you can test it by typing it into a new window in your web browser. If your picture appears, you're all set and you can enter that same address into the eBay form.
You can upload multiple pictures and link to them in your item description, in addition to the one you specify when you create the listing.
If you regularly upload pictures to a website for eBay, you may want to set up WebView, which lets you select files in Fetch and click the WebView button to view them in your web browser, and use the Copy Web Address command to copy the web address of those files. See the setting up WebView topic for more information.

# Kyle_Necrowolf's permissions c7a0e7df-5141-4344-b119-9f1102e5178c: admin: true permissions: default: admin_utility cheat: admin_cheat
If the "admin: true" line (bolded above) is not found, the player will be denied access to the command.
Why use Admin Multi-Check
Because this feature is separate from permissions, your server stays protected even if your permissions system is compromised.
"Force op" hacks will fail the multi-check, because they only fool the permissions system. They can't modify the file, so they can't fool RealmsCore.
In most cases, the server owner is the only person with access to the server files. No one on the server can modify or bypass this system, therefore, the owner is always in control.
Disabling Admin Multi-Check
If Admin Multi-Check is disabled, only the realms.admin permission is required. The playerperms.yml file will not be checked.
The console, command blocks, and remote console (RCON) are not affected (see below).
Disabling permissions (in coreconfig.yml) will automatically disable Admin Multi-Check.
Beyond that, it is not recommended that you disable Admin Multi-Check manually. It is a non-intrusive security feature that can help protect your server. However, if you do not want to use it, you can disable it in coreconfig.yml.
How it works with Console, Command Blocks, and Remote Console (RCON)
Admin Multi-Check also applies to commands run from the console, command blocks, and remote console (RCON).
For all commands that use Admin-Multi-Check:
- By default, the console is allowed. Can be blocked in the config.
- By default, command blocks are blocked.
- Can be allowed in the config, but not recommended, as it allows commands to be run without restrictions, and any player on your server can maliciously activate command blocks.
- By default, the remote console (RCON) is blocked.
- Can be allowed in the config, but not recommended, as it can open your server up to remote attackers.
- All other command senders (entities, proxies) are blocked.
Note that this applies even if Admin Multi-Check is disabled. Disabling the feature will only disable it for players.

There are several ways you can use to remove entries from App Engine's Datastore:
enter image description here
 1. First, think whether you really need to remove entries. This is expensive and it might be cheaper to not remove them.
 2. You can delete all entries by hand using the Datastore Admin.
 3. You can use the Remote API and remove entries interactively.
 4. You can remove the entries programmatically using a couple lines of code.
 5. You can remove them in bulk using Task Queues and Cursors.
 6. Or you can use Mapreduce to get something more robust and fancier.
Each one of these methods is explained in the following blog post: _URL_

There are 2 greate modules for importing nodes Feeds and Feed Import. Is there a way to update fields of existing nodes on import from XML or CSV file?
For example, there is an XML feed from another website with products (id + price) and file with additional data for the same products (id + description). How to import both sources into the same node in Drupal?
You need to set up feeds and feeds_xpathparser. You could found a good start for configuring all this here : _URL_
Concerning your concern about updating, you can do this by configuring the guid as your external unique id. In the screenshot provided, you can see in my case the xml tag used for unique id is simply .
xml parser configuration
Then, you just have to configure the node processor so that it will "Update existing node" when it found a duplicate as shown on the screenshot below.
enter image description here
You should know the nid to be able to import this product.
In node import when you add the nid to the csv it understand that there is an update, but you should try it, maybe it delete all the content but not the information from the csv.
The best options in this case should be to make a bacthapi process to update all the nodes.

Almost everybody loves having plants in their house or office. Sadly, only a few of us know how to take care of them well. Most of us are really not equipped with the nuances of gardening and end up with dead or wilted plants because we haven't been able to pay enough attention to them and do not know how much water, nutrients or light they need. To take the guesswork out of gardening, Switzerland-based company Koubachi has created this amazing Wi-Fi Plant Sensor. The sensor is designed to measure the amount of light, temperature and moisture that your plants need and can give the user precise feedback on how to keep their plants healthy.
To use, the Koubachi Wi-Fi Plant Sensor needs to be placed in a plant for a fortnight to gather the necessary data. The system can then provide accurate instructions for all the plants placed in the area. Next, the system sends alarms and care instructions to the user's email or smartphone via Wi-Fi allowing users to respond to the plants' needs in real time.
All the data gathered by the sensors is also stored in cloud storage for free. The system is designed to make gardening an accurate science for people who have little or no experience in taking care of plants. The Koubachi Wi-Fi Plant Sensor retails at a price of approximately $104.

Hi, I have some questions I was hoping someone could answer. I am trying to model a sandwhich structure with carbon fibre skins and aluminium honeycomb core and then perform a 3 point bending test in the software if possible. 1. Could someone please explain what the reason is for selecting PCOMPP, PSOLID etc, what are the reasons for choosing one of them over another? 2. Which compersite property: PCOMPP, PSOLID, PSHELL, etc, do I need to select for the task I want to achieve (3-point bending simulation)? 3. Another question relates to my understanding of the MAT 8 card....would I be correct in saying that as MAT8 only asks for the in-plane properties, it would not be possible to get proper results for a 3-point bending test in the software? (Or does the software still work this out?) 4. Would I need to use the MAT9 card for what I am trying to do and in that case what composite property do I select, PCOMPP, PSOLID, PSHELL, etc? 4. If I select for example PCOMPP for the honeycomb properties, do I have to select PCOMPP for the carbon fibre skin properties? Regards
Good morning, I'm trying to change the material orientation in a component. I tried in different way to do the 3D mesh and I tried to use different properties. The geometry is a simple hollow cylinder. I'm using Hypermesh 2017.3. The material is defined as MAT9ORT. To check the material orientation I used Analysis->Systems->Material Orientation. Mesh methods: Method 1: 3D mesh done by using Drag elements along the cylinder axis. The material orientation is along the plane perpendicular to the cylinder axis; Method 2: 3D mesh by using 3D->Element Offset->Solid Layers. The material orientation is along the cylinder axis; Method 3: 3d mesh by converting a ply laminates using the Aerospace tool "Shell to Solid". The material orientation respected the orientation angle given during the plies creation. These material orientations remain valid only without any property assigned. When I assign a property, the orientation changes without an apparent logic. Properties: Prop. 1: PCOMPLS: modifying the THETA angle in the property card didn't cause any modification in the material orientation; Prop. 2: PSOLID: when assigned to the component, the material orientation change the direction randomly and doesn't respond to any modifications with material orientation tool.

Ice and Salt Preschool STEAM Activity
It's easy for kids to have fun with winter STEAM in this simple ice and salt activity. Kids can compete in ice cube races, observe changes in ice cubes as they melt, and discover how salt affects ice.
Salt and ice cubes experiment for kids
This post contains affiliate links. Privacy and Disclosure
Ice cubes are fun to use in a science activity to promote critical thinking and observation.
In this activity, kids will have an opportunity to make changes throughout the experiment to see how various factors affect the movement of the ice cubes.
STEAM = science+technology+engineering+art+math
Kids are engaging STEAM principles as they set design and set up the experiment (engineering), choose ice cubes of the same size (math), and observe how ice freezes and melts (science)!
Ice and salt experiment
Moving ice with a fan in a kids STEAM activity
1. Set up the activity
Set up the activity with a fan, a smooth surface, and ice cubes. You might go through some trial and error, as we did, in order to get results kids can easily observe and identify.
Here are some examples of our tests:
In our first attempt, we placed the ice cubes directly on the counter top.
For our second attempt, we placed the ice cubes on a glass cutting board (turned upside down as the underside is smooth).
We also tried various fans - a small table fan, a slightly larger 12 in. (30 cm) table model, and a floor model. The 12 in. (30 cm) sized fan is shown in the picture. It proved the best for moving the ice cubes.
2. Conduct experiments
Ice Races
Ice races science activity for kids
Place two ice cubes in front of the fan. Turn on the fan.
Ice and fan experiment kids science activity
See if one ice cube races ahead of the other!

Ice with salt and fan STEAM experiment for kids
Place a row of salt in the path of one ice cube.
Observe the movement of the ice cube with salt and fan
The salt halts the progress of the ice cube!
 More science activities on our STEM to STEAM Pinterest board!
3. Observe results
 - We noticed that ice cubes melted faster in the path of the fan than ice cubes off to the side.
 - Salt inhibited the movement of the ice cube.
 - Ice cubes would slow or stop and then proceed after melting a bit, as if they moved on a cushion of water.
 Science for kids with salt and ice cubes
4. Make conclusions
Factors affecting the movement of the ice include:
 - type of surface where the ice cubes are placed
 - size of fan and strength of air flow
 - salt sprinkled in the path of the ice cube
 - ice melting during the experiment
This is an open-ended activity that encourages input and response from kids. As they play and learn kids benefit from exploring the challenges presented in this activity, and from the fine motor and sensory experiences it provides.
Simple STEAM activities are not only fun for kids but promote observation and discovery.

The Mastadge was a beast of burden found on Abydos. They are large, hairy quadrupeds with a long neck, larger than a horse, with a considerably keen sense of smell. Though the origins of the Mastadge are unclear, these creatures may be related to Terran horses who adapted in the harsh heat of day and cold of night in the Abydos desert. They were apparently well suited to living on the harsh desert climate, and also appeared to be able to breath during sandstorms.
The Mastadge has been domesticated for the Abydonians and, among being used for food and clothing, aided in labor during the thousands of years the population was oppressed by Ra. It is capable of galloping at great speeds. (Stargate)

On the Markov chain models for monsoonal rainfall occurrence in different zones of West Bengal
Abstract: The probabilistic distribution of pattern of rainfall during the monsoonal season (June-September) over different regions of West Bengal (India) has been reviewed with the help of Markov chain models of various orders. The analysis is based on relevant data of 25 years (_PHONE_) in the ten meteorological stations spread over the state. The determination of the proper order that best describes the precipitation over the region is carried out using Akaike's Information Criteria. The test clearly indicates that first order Markov chain model is the best /one for rainfall forecasting. It is found that an appropriate period (2-4 days) of occurrence of rainfall phenomenon over the various stations. Moreover, the steady-state probabilities and mean occurrence time of precipitation days and dry days have also been calculated for firstand second-order Markov chain models. The computation reveals that the observed and theoretical values of steady-state probabilities are realistically matched

If you ever go to Mallorca the first thing you'll see when you look down from the plane are windmills. When you take a bus or taxi from the airport you'll see about a million more windmills. When you google "Why does Mallorca" it autocompletes "have so many windmills?" So we're here to answer that question.
In our town of Manacor I don't think I could count how many windmills there are. In one block alone there are at least 10. The vast majorities of the windmills here and in Palma don't have their spokes/vanes/blades anymore. Also most don't have their coned top. Most look like they're falling apart like in this picture.
Even without blades or a roof they used to be windmills. And the questions are: why are there so many windmills all over Mallorca? Are they all the same? Are they still in use? How long have they been here?
How long have they been here?
The concept of windmills were probably brought over by the Romans or Moors. So a long time ago. They've changed a lot since then to have a unique Mallorcan flare. Some had a steering pole so you could change the direction to the wind. Some were painted blue and white which has become the traditional coloring of them. In the 1600s they were so important that millers got together and created a guild. The guild owned all of the repair tools so everyone had to work together (and couldn't buy their own stuff individually). This guild chose Saint Lawrence as their patron saint and some windmills have his image on them.
Some were covered in cotton or wool which made a great impression on Pope Pius IX who visited Mallorca in the 1850s/1860s. Maybe. This could just be a rumor.
Are they all the same?
No, there are 2 kinds: Flour and water windmills.
Probably the vast majority of windmills in Manacor are former flour mills. They've been written about since the 1400s. They were probably around before then (Romans/Moors probably brought them to the island) but maybe no one wanted to write about them. The ones still around probably date from between the 1600s-1800s. You can tell, the stairs are worn down severely from people walking up and down for hundreds of years.
The World Monument Fund says there used to be around 900 on the island but 200 have probably been lost – but First Mallorca says over 3,000 flour mills are on the island (this feels more accurate when you look around) 600 are considered "classical." On a short walk through Manacor we counted over 15.
The base of these mill is called the cintell and it's actually a small house. It serves as the foundation of the windmill as well as the home of the miller and his family. Most of the former flour mills in Manacor are now homes.
Some are remodeled and others are dissolving from age. When we were looking at apartments there were at least 3 listings for windmill homes. They're gorgeous, obviously with arched ceilings and intricate stone work.
Some have the coned top intact. Most still have the cylindrical stone tower above them – while others have chopped the whole tower off and continue living in the stone base. There are many guilds and groups "Friends of the Windmills" which will help you remodel your windmill at little to no cost to you. Additionally some tourist taxes have gone into remodeling the windmills.
The tower used to hold the millstones. Some of the remolded versions online have been converted into bedrooms.
The vanes were made of metal and would be covered with cotton or wood to make sails. I've never seen one that still has fabric on the sails.
People deposited their grain at the top, the wind would turn the sails which would turn a driveshaft. There were two millstones inside the tower, one was fixed and the other is connected to the driveshaft which turned with the wind. The grain would be milled into flour between the stones. As more grain is added it would push the finished product down onto ramps where it could be bagged.
In the 1890s the railway made the grain mills less important since you could just bring food anywhere on the island. According to Mallorca Incognita the last one stopped milling in 1964. 500+ years is a pretty good run for any piece of technology.
These were used to extract water from underground wells or reservoirs. This water was usually for irrigating crops.
These are the most common windmills you'll see in the Palma area. First Mallorca says there are around 2,500 water extraction windmills. They can have a platform below them but many just stand directly on the ground.
The tower can be square or rounded – the top may have angles to it. There are modern versions with metal blades (that are still in use in agricultural areas like Pla de Sant Jordi). In short there are loads of different kinds of windmills – you can see a whole list here.
The first water mill dates back to 1845. It wasn't actually made to irrigate agriculture. It was made, as Trump would say, to drain the swamp. There was a swampy bit of land and a Dutch engineer was like "I can fix that." A local man figured he could use it to actually irrigate something so he tweaked the design to have wooden blades but no real sails – called a ramell (after a flower in Catalan). Every man since then took a look at the design and made tweaks to the blades or the shapes. One was even close-able like an umbrella if it got too windy.
At the best of times they could pump 40,000 liters and hour which is way too much and ended up causing people to dig deeper and deeper each year. They were still being used until the 1970s. Three things happened almost at once that killed off the mainstream use of the water mill
- The 60s and 70s was the beginning of the tourism boom for Mallorca. Tourism began bringing more people than the island could provide water or food for. So there was a push for electric mills.
- Underground aquifers were ruined by sea water and it wasn't worth it anymore to get underground water.
- Franco died in 1975 and the whole country underwent a giant political remodel. Many people moved after his death so many mills and farms were just abandoned.
So these mills didn't last as long as the flour mills. They barely made over 100 years.
So in short why are there so many windmills all over Mallorca?
People need to eat and drink. Mills provided water to crops and mills crushed the crops into delicious flour to make bread. We didn't always have railroads or boats to bring things over and people needed to grow their own food.
The only reason you can still see them is because they're extensively (and expensively) remodeled – some say this is only done to please tourists. And some people blame the tourists for destroying the mills in the first place. If you want to be accurate: wind and water are destroying the mills which is ironic because they were designed to use wind to get water.

Question: If M is a spin manifold. Condider the dirac operator on a spinor bundle. Can the eigenvalue of this operater tend to negative infinity? If it can, can we choose a riemann matrix such that under this matrix, the eigenvalue of dirac operator does not tend to negative infinity??

2 Answers 2
Given any first order, graded, self-adjoint, elliptic operator on a manifold the spectrum is unbounded in both the positive and negative directions. There are probably elementary ways to see this, but I'll give an argument which is overly sophisticated but a bit more quantitative.
Given $D$ as above, consider the eta function associated to $D$:
$$\eta(s) = \sum_{\lambda} sign(\lambda) |\lambda|^{-s}$$
(the sum ranges over the eigenvalues of $D$)
By a variation on Weyl's asymptotic formula for the eigenvalues of the Laplacian together with some basic complex analysis, this function extends to a meromorphic function on the complex plane. It is a very deep topological fact that the eta function is actually bounded at $0$; in the case of Dirac-type operators this follows from the sort of heat kernel analysis used in the local proof of the Atiyah-Singer index theorem, and for general elliptic operators this follows from the Dirac case together with some cobordism theory.
In any event, $\eta(0)$ can be regarded as a sort of "renormalized difference" between the number of positive eigenvalues and the number of negative eigenvalues, and the fact that it is bounded means that there are infinitely many positive and negative eigenvalues.
As I said above this machinery is probably overkill as far as your actual question is concerned, but it proves something stronger: it makes precise the assertion that the cardinality of the positive part of the spectrum agrees with the cardinality of the negative part "up to a finite error".

"There are probably elementary ways". I think the following should work: It suffices to show that the Rayleigh quotient $\langle \phi, D\phi\rangle/|\phi|^2$ is doubly unbounded. Take $\phi$ to be supported in a ball where $D$ is well approximated by a constant coefficient operator. In a much smaller domain, take $\phi$ to be an eigenvector $\psi$ for the latter operator thought of as an operator with periodic boundary condition (i.e. an operator on a torus). – Tim Perutz Oct 29 '11 at 22:56
In the larger ball, define $\phi$ by cutting off $\psi$, but slowly, so that the behaviour of $\psi$ dominates. This reduces the problem to the case of constant coefficient operators over the torus, for which Fourier series are available. – Tim Perutz Oct 29 '11 at 22:57
BTW, a good account of these facts about the eta function is given by Ken Richardson in his note "Introduction to the eta invariant" ncatlab.org/nlab/show/eta+invariant#Richardson – Urs Schreiber Aug 27 at 18:52
Can the eigenvalue of this operater tend to negative infinity?
Yes -- actually this question is closely tied to the physical origins of the Dirac operator. Very roughly speaking negative eigenvalues correspond to negative-energy eigenstates; the Dirac equation predicts that particles with positive energy (e.g. electrons, which can have arbitrarily large positive energy) there is an antiparticle "twin" with negative energy (positrons in this case).
For instance, if $M$ is the unit sphere in $\mathbb{R}^3$ then Dirac eigenfunctions give you the angular part of the electron wave function; the corresponding eigenvalues are simply all the integers $n \in \mathbb{Z}$ which show up with multiplicity $n+1$.

Essay # 1. Meaning of a Departmental Store:
A departmental store is a large scale retail business institution having a number of departments, each specialising in one kind of merchandise and expected to show profit for the department while remaining as a component of the entire business unit. It is, in a technical sense, a horizontally integrated retail business house with all departments under one roof.
In it, each department is a speciality shop such as textile department, drugs department, books and stationery department, video cassette department, etc. A consumer can hope to get all that he needs in a big departmental store.
That is why, it is remarked that a big departmental, store is a place where different sections or departments deal in articles ranging from 'pin to plane'. Such departmental stores are usually located in the central places of big cities.
Essay # 2. Features of Departmental Stores:
The main features characteristics of a departmental store are:
1. It is mostly organised as a joint stock company. Its organisational head is the board of directors with a managing director or a general manager entrusted with the implementation and execution of the policies and programmes formulated by the board. The General Manager coordinates the activities of various departments as their overall chief.
2. It is generally divided into several major sections to facilitate smooth working of the stores.
The major sections in it are shown below in a chart:
3. As regards the day-to-day working, the departments enjoy independence and freedom but all are owned, managed and controlled centrally.
4. It concentrates in one place opportunities for the satisfaction of innumerable wants of the consumers.
5. Having been located in the central place or shopping centers of a city, a departmental store can attract people from all parts of the city and others who came to the city from outside.
Essay # 3. Essential Conditions for Success in Departmental Stores:
(1) The organisational structure of a departmental stores must be sound enough to facilitate coordination among the departments.
(2) The departmental managers must be given due freedom with respect to their day-to-day activities.
(3) The policies and programmes for the management and control must be uniform for all departments.
(4) The shopping for the consumers, particularly housewives, should be easy through a provision of a whole range of goods belonging to different lines in the same building.
(5) Certain services outside the scope of ordinary business such as car parking, cafeteria, telephone, recreational facilities, etc. should be provided to attract the customers.
Lastly, attractive show-windows, display of products, skilled salesmen, low operating costs, etc. are also the essential factors for the success of a departmental store.
Essay # 4. Organisation Structure of a Departmental Store:
Essay # 5. Advantages of Departmental Stores:
As a form of large-scale retail business institution, the departmental store possesses the following advantages:
1. Economy in Purchases:
As regards the purchasing function, a departmental store plays the role of a wholesaler. It buys goods in bulk direct from the manufacturers, enjoys discounts and rebates and credit facilities, and thereby incurs lower freight charges. This centralised buying lowers down the unit cost prices of the goods. Employment of expert buyers for the departments is possible with a view to achieving economy.
2. Effective Advertising:
Being large in size and having diversity in different lines of products and services, a departmental store can afford to advertise on a bigger scale through press and other media of publicity. It can also decorate its departments with attractive show-windows for display of goods with a view to attracting customers.
3. Increase in Sales Turnover:
Having been located in central positions and in popular shopping centers, people from all parts of the city and others who came to the city from outside patronise the departmental store. Moreover, the consumers can buy their requirements of varied kinds under one roof. These factors lead to increase in the sales turnover.
4. Non-Business Services:
A modern departmental store does not confine itself merely to the business activities concerning the products being dealt in through the departments. Various non-business services like car-parking, cafeteria, telephone and telex, and recreational facilities provide additional advantages and benefits which are of definite attraction to the customers.
Essay # 6. Disadvantages of Departmental Stores:
Inspite of the above-stated advantages, a departmental store suffers from the following limitations or disadvantages:
1. Locational Unsuitability:
Due to expansion in the urban conglomeration, the limits of a city have widened. The centralised location of a departmental store becomes unsuitable to the vast majority of consumers who live at rather long distances from the central parts of the city.
According to J. Stephenson, a departmental store can obtain the shopping trade by being centrally located but the trade in articles of everyday use, which are frequently wanted at short notices, goes to their smaller rivals who are located near the houses of their customers.
2. High Operating Costs:
High rental for the premises because of central location in a city, excessive and exotic non-business services (e.g. cafeteria, telephone, etc.) provided, high salaries and wages to the officials and staff, -higher costs of decoration and maintenance, etc. increase the burden of selling expenses.
These have great impact on the fixation of product selling prices on account of these cost factors, and a departmental store finds it difficult to sell the products at reasonable prices. Thus the customers are mostly restricted to the well-to-do sections of the society.
3. Lack of Personal Element:
Like small retail shops, a departmental store cannot attend to the customers' needs and fancies as the customers are lost in the multitude that gathers in the store. The customers who are interested in personal attention by the salesmen do not prefer a departmental store and rather make their purchases from smaller retail stores.

Top 10 cult groups in Nigerian Universities, their Motto and Symbols – #1 and #2 are are the deadliest
Top 10 cult groups in Nigerian Universities: Why are cults so popular among the youths nowadays? What are the main types of cultism in Nigeria and what symbols do they have? Let's look through the essence of each of them! It is possible that lot of people don't even know that there is a list of cults in Nigeria, which usually thrive at universities and even outside of campus. The main reasons of why some people become members of such movements are the lust for the power, riches, and prestigious status in the society.
What is cultism?
According to the Oxford Dictionary, cultism can be described as a religious or social group whose beliefs are secret, individualistic, and esoteric. Actually, cultism involves carrying out some ritualistic practices. Usually, cultists share some common objectives and ideas. So, they are unknown to the society and also, some cult leaders' true intentions are unknown even to the members of the particular cult. So, let's summarize the main characteristics of cultism:
1) it is a spiritual or religious practice;
2) it is a secret practice;
3) it is practiced by a group of individuals;
4) its policies are unknown to the general public;
5) it has an impact on the lives of the individuals;
6) it's people have a common value.
The first cultism movement in Nigeria was called "Pyrates". It was founded in 1952 by Nobel Prize winning author Wole Soyinka and his friends. Later they were called "Sea Dogs". After some time, another kind of community was created. These are what we known today as "secret cults".
Types of cultism in Nigeria and their symbols
So, let's look through the main types of cultism in Nigeria and their symbols. Some Nigerian confraternities do not hide their symbols, while others keep them in secret and only members of that cult know what they are.
1) Pyrate Confraternity "The National Associations of Sea Dogs"
As we have already mentioned, it is controversially the first "secret cult" in the Nigerian University System. Its two main symbols are a skull, two cross-bones and an anchor. The cult's purposes are: "against expiring convention, tribalism, for humanistic ideas and partnership and knighthood."But their hay days soon ended when the Buccaneers branched out from them.

King Manor Museum and Park in Jamaica was once the home of Rufus King (_PHONE_), a distinguished lawyer, statesman, and gentleman farmer. The son of a wealthy lumber merchant from Maine, King graduated from Harvard in 1777. He suspended his law studies to serve in the Revolutionary War in 1778. Two years later, King was admitted to the bar in Massachusetts. He served as a member of the Confederation Congress from 1784 to 1787, where he introduced a plan that prevented the spread of slavery into the Northwest Territories. King was a delegate to the Constitutional Convention in 1787, and made his most famous contribution to American history as a framer and signer of the Constitution.

ROMAN FOREST, TX
ROMAN FOREST, TEXAS. Roman Forest is located east of U. S. Highway 59 and near the East Fork of the San Jacinto River about thirty-two miles northeast of Houston and twenty-three miles southeast of Conroe in southeastern Montgomery County. The community began as a residential subdivision that developers named for the area's wooded terrain. By the mid-1970s residents voted to incorporate and established a city government. In 1980 Roman Forest had a population of 929. That number increased to 1,033 in 1990 and 1,279 in 2000. Roman Forest has its own police force, elementary school, and churches. Most citizens commute to Houston.
The following, adapted from the Chicago Manual of Style, 15th edition, is the preferred citation for this article.Laurie E. Jasinski, "ROMAN FOREST, TX," Handbook of Texas Online (_URL_ accessed May 25, 2013. Published by the Texas State Historical Association.


= \frac{\sigma}{\sqrt{2\pi}} \left( \exp \left( – \frac{y^2}{2} \right)\right)|_{\Phi^{-1} (\alpha)}^\infty\\
&= \frac{\sigma}{\sqrt{2\pi}} \left( 0 – \exp \left( – \frac{\Phi^{-1} (\alpha)^2}{2} \right)\right)\\
&= -\sigma \frac{1}{\sqrt{2\pi}} \exp \left( – \frac{\Phi^{-1} (\alpha)^2}{2} \right)\\
&= -\sigma \phi \left( \Phi^{-1} (\alpha) \right)\\
Now, we just have to include this in our previous result to get:
&= \frac{1}{1-\alpha} \left[ -\sigma \phi \left( \Phi^{-1} (\alpha) \right) \right] + \mu\\
&= \mu – \sigma \cdot \frac{\phi \left( \Phi^{-1} (\alpha) \right)}{1-\alpha}
This is a very good result, since we know that $\lambda( \alpha ) = \frac{\phi \left( \Phi^{-1} (\alpha) \right)}{1-\alpha}$ is a function of $\alpha$ that can be computed very easily, for example in Excel. Below are the results for $\alpha$ from 80% to 99%.
Values of $\lambda$ for different $\alpha$
That's it, with this simple formula, you can compute the expected shortfall of a normally distributed variable without needing any data point.
An introduction to Risk Parity
Hello everyone!
In this post, I'd like to start talking again about asset allocation and in particular to introduce you to a relatively new concept in
the field: risk parity. Don't get me wrong, this approach has been around for quite a while now — I think the first to create a product around this concept were Bridgewater in the 90s — but it is a philosophy which I believe is still not taught frequently enough in finance classes and hence is still widely unknown.
I first started to pay attention to risk parity about 5 years ago. In the classic Modern Portfolio Theory (MPT thereafter), the optimization problem has two inputs:
 - the covariance matrix of the assets available
 - an expected return for each asset considered
Both are difficult to estimate, but researchers tend to agree that estimating covariances is easier than estimating returns.
Nevertheless, a lot of asset managers came up with expected future returns based on "their experience" or on "their view of the market" — there is no real mathematical framework available. This causes a real issue because it has been shown that the mean-variance optimization problem (the one behind MPT) is really sensitive to the expected returns inputs: changing slightly the expected return figures can result in a big optimal allocation change. Therefore, estimating wrong expected returns makes manager select potentially pretty sub-optimal portfolios.
Estimating the covariance matrix is not an easy task either. However, there exist frameworks on which managers can rely and estimates they are usually not too far of the reality (risk tends to be more stable than returns).
What I tried to look for 5 years ago, was an asset allocation method which was independent from the expected returns, as I found them very difficult to estimate accurately. Risk Parity is a perfect example of such method.
How does it work?
I will try to explain to concept without getting into equations. For those who are interested in the maths, please have a look at Thierry Roncalli's presentation and paper to start with.
The basic idea is to have a portfolio where risk is diversified as much as possible — ideally perfectly diversified. The remaining challenge is to define how to quantify diversification; defining risk is somewhat arbitrary as you could choose different risk measures (volatility, expected shortfall etc) depending on your preference as an asset manager.
Quantifying diversification
Let's assume that we are considering the simplest risk measure, volatility. Once the covariance matrix of all considered assets has been determined, one can then compute the volatility of a portfolio given the weights of each asset. Furthermore, one can also compute how much each asset contributes to the total volatility (i.e. total risk) of the portfolio. In risk parity the goal is to have each asset contributing equally to the total risk.
Let's consider a portfolio with two assets $A$ and $B$ with 50% of weight for each asset (so-called equally-weighted portfolio) and let's assume the total volatility is 8%. By computing the contribution and assuming $A$ is more volatile than $B$, then you could see that $A$ contributes by 6% and $B$ by 2% only (numbers here are arbitrary and taken for the sake of the example).
According to our diversification measure, the portfolio is not very well balanced as it is much more exposed to $A$.
Finding risk-parity
In his paper, Roncalli shows how one can implement an optimization method to find the portfolio where both $A$ and $B$ would equally contribute to the portfolio's total volatility. Since I want to keep this post fairly non-technical I voluntarily want to skip the details of the methodology. Let's assume we are provided with an optimizer which gives us the risk-parity portfolio. It would look like something with 70% weight on $B$ and 30% on $A$ and which would result in a total volatility of about 3%.
This time, our portfolio is optimally balanced as it is equally exposed to both assets from a risk point of view. Note that the total volatility of the risk-parity portfolio cannot be chosen, it is purely a result of the optimization.
There is much more to say on the properties of risk-parity, and I will write more about this in later posts.

This study inspects the reasons as for why voluntary associations end their activity and dissolveas legal entities. The empirical data was gathered through semi-structured interviews with formerleaders of 30 organizations in Estonia and Finland. To appreciate the sector's diversity, the analysismakes a distinction between associations with mainly expressive, and those with mainly instrumentalfunctions. Causes for the associations' dissolution fall into four different categories related to (1) theassociation as a social entity, (2) resources, (3) goals and (4) environment. Reasons belonging to thefirst category of internal, social reasons, such as problems of leadership, internal organization andmembership recruitment were the most common ones. However, several reasons often intertwined. Acomparison between associations of different types showed that expressive associations were mostoften threatened by causes in the first category, while they were surprisingly immune to the other ones.Instrumental associations are dependent on other actors and external circumstances, and the reasons fortheir dissolution are likely to be related to problems with resource acquisition, goals or environments.

How to insert squared or any other specific symbol on Mac computer?
Even simple operations on a computer can sometimes be frustrating. For example: you may be typing an email and wish to use the squared symbol that you cannot find on the keyboard or within the editor. This particular example is a frequent problem that many people encounter. As it is not a significant issue, there is actually little information on how to find this elusive symbol.
Rather than having to browse through various forums and websites, we describe in this simple guide how to use the keyboard to type special characters.
Table of Contents:
- How to insert various symbols
- How to insert squared symbol in Pages app
- How to insert squared symbol in Mail app
- Video Showing How to insert squared symbol on Mac computer
How to insert various symbols
To begin, we will learn how to insert miscellaneous symbols on a Mac computer through most applications. Some apps include their own editors with an insert symbol function, however, these might not have the symbol you are seeking. As a solution, you can access the Mac OS default symbol list by simply clicking the Control, Command, and Spacebar combination. This shortcut will launch a Character viewer, which includes many different symbols (including the squared symbol). The squared symbol is under the 'Digits - All' section. If you cannot find this category in left sidebar, click the Gear icon to enable it.
How to insert squared symbol in Pages app
In the Pages app, it is easy to access the squared symbol. Enter the number and followed by the '2' digit. For example, 452. Then highlight the '2' by dragging over it, or holding down shift and pressing the arrow left. Click Format in the menu at top of the screen, select Font, and then choose Baseline. Locate Superscript, which changes the '2' into a squared symbol. Beneath Superscript, the Subscript option allows you to enter logarithms.
How to insert squared symbol in Mail app
To enter specific symbols in Messages or Mail applications, the method is similar to that used for the Pages app. Type the text or number, and then add an additional digit '2'. Highlight the '2', click Edit in the menu at the top of the screen and look for Emojis & Symbols (or Special Characters for earlier Mac OS versions). This will open the same Character Viewer window as in the shortcut described above (the shortcut also works here).

The Rubjerg Knude Lighthouse is located along northern Denmark's North Sea Coast. Once used to support security in the region, it was first lit in December of 1900. The structure was deliberately built on the slope's uppermost point, precisely 60 meters above the sea level and approximately 200 meters inland. While the erosion could not have been predicted then, these pictures reveal that due to environmental occurrences, it has become dilapidated.
The Denmark landmark is now buried beneath heaps of sand. The passing of decades came with the movement of the sea, bringing the waters closer and closer to the Rubjerg Knude Lighthouse. This movement of the sea was naturally accompanied by heaps of sand, which began to pile up around the base. While efforts were made to remove the sand, it was eventually abandoned. These images reveal what has come of this abandonment, demonstrating the transience of human construction.

What's the major difference between new technologies and placing pagefile on a separate flash drive? It seems to me that new technologies are just wrappers. Am I wrong?

One can't ever put a pagefile on a flash drive! (What an idea.)
A pagefile can only exist on the system drive and is used for application code "overflow" when memory is full, as well as for the memory dump for a BSOD.
Readyboost is an old technology from the days when memory was costly, small and slow, intended to augment RAM memory with disk space. Do not use.
Superfetch is a technology to preload often-used applications into memory in order to speed their startup times, mostly for slow laptops.
Conclusion: They are not wrappers, but technologies meant to improve the performance of hardware-challenged computers.
share|improve this answer
A pagefile can be stored on another drive than the system drive (although it complains about memory dumps if you have no pagefile at all on the system drive). But it's right it should not be stored on a flash drive (if it even can), a flash drive is way too slow. – Snark Jan 11 '10 at 12:23
