Duchess of Cornwall Inn
A stunning bar / restaurant in the heart of Poundbury
Built in 2016 by the Duchy of Cornwall but operated by Hall & Woodhouse, the pub is named after the Duchess of Cornwall at the direct request of the Prince of Wales and was opened by the Prince and Duchess. The pub contains many artefacts from the Woodhouse family including a Dorset oak bookcase from West Lodge (the Woodhouse family's home in the 20th century); the great brewing copper that forms the entrance is taken from the King & Barnes brewery which Hall & Woodhouse acquired in 2000. The Badger glass (created by Dorset glassblower Stuart Wiltshire) is the largest hand-blown glass in the world.
The building is split into sections over three floors and is designed around the Woodhouse family and their interests and passions. Downstairs you'll find the Copper Bar and the Pantry with long bench style seating for a more relaxed experience. Moving up the grand central staircase is the dining room with its open kitchen and then to top it all off, outside is our beautiful terrace, the perfect place to relax on a sunny evening.
Our Dining Room on the second floor is a must for couples and small groups alike, looking for a slightly more formal dining experience. Light and airy, with walls adorned with traditional art and caricatures of Hall & Woodhouse family members from many generations, attractive chandeliers, traditional dining furniture and table service, our 'brasserie' style experience offers classically simple British food with reliable dishes that everyone wants to eat, rather than those found in an elaborate restaurant.
Our delightful, relaxed pantry area on the ground floor evokes memories of the kitchen at the H&W brewery at the start of the 19th Century, where you can dine in your own time surrounded by an eclectic mix of old kitchen equipment and more contemporary kitchen produce, some of which is incorporated into our fantastic range of menus.
Our snug Common Room on the ground floor is the ideal place to relax and unwind, much like the loafing culture of a college common room, where different social groups form, merge and disperse throughout the day. With wooden panelling, comfortable leather chairs and sofas, it's perfect for place to relax with a pint or cup of coffee, a bite to eat and a leisurely read of the daily newspaper.
No public house is complete without its central focal point, the bar of course! Our grand bar is no exception, showcasing our exceptional range of cask conditioned and bottled beers, which are only available in H&W pubs and bars, so we can guarantee the very best quality, right from the heart of the Dorset countryside. In addition, our great range of lagers, ciders, wines, spirits (including a great choice of national, regional and local gins), cocktails and Champagne by the glass, means that we have something for everyone.
View our Drinks
There's nothing quite like relaxing in the great outdoors and our terrace is the ideal place. Open year round and adorned with plenty of comfortable wicker and traditional patio furniture it's the perfect place to grab a bite to eat and a drink.

Introducing Forum Lager
Forum is a 4.2% refreshing Helles style lager, with a delicate flavour from the Weihenstephan yeast and a subtle fruity lemon character from Hallertau Blanc and Huell Melon hops.
The name refers not only to Blandford Forum, the location of the H&W brewery where this new lager is brewed, but also to a meeting or gathering where ideas and views can be exchanged. And where better to meet and put the world to rights than in a traditional British pub. So what are you waiting for, make sure you try a pint next time you visit.

Q: How can I user SpEl to sort a Collection? I have a List that I want to sort using a spring expression. I am currently using a Comparator and a TreeSet whereby the Comparator takes a spring expression and compares the result of parsing that spring expression on each member of the list.
It probably works (I haven't tested it yet), I gusted wanted to find out if anybody knew of a better way.
This is what I currently have for the Comparator. :
public class SpringElComparator implements Comparator<Object> {
    private static ExpressionParser parser = new SpelExpressionParser();
    private static Map<String, Expression> expCache = new HashMap<>();

    private Expression exp;

    public SpringELRule(String expression) {
        exp = expCache.get(expression);
        if(exp == null) {
            exp = new Expression(expression);
            expCache.put(expression, exp);
        }
    }

    @Override
    public int compare(Object o1, Object o2) {
        Object c1 = exp.getValue(o1);
        Object c2 = exp.getValue(o2);
        int result;
        if (c1 instanceof Comparator) {
            Comparator comparator1 = (Comparator)c1;
            Comparator comparator2 = (Comparator)c2;
             result = comparator1.compare(comparator2);
        } else if (c1 instanceof Comparable) {
            Comparable comparable1 = (Comparable)c1;
            Comparable comparable2 = (Comparable)c2;
            result = comparable1.compareTo(comparable2);
        }

        if(result == 0) {
            return -1;
        } else {
            return result;
        }

    }
}

If you haven't seen these alerts before don't panic!
These are new handy alerts that monitor the CPU usage of the system alongside the Render Time (GPU usage) to determine if the system is overloaded.
Overloaded does not mean the system is damaged, or that it is overheating.
It simply means that we think the computer is not quite fast enough to keep up based on your current vMix production setup.
This means the computer's processor usage is a bit too high for the best results in vMix.
1. Turn off your recording and streams. If the warning goes away then these are the cause of the high usage.
If you are streaming to multiple providers, you may need to reduce the number of providers or upgrade the computer.
You can also try streaming at a lower quality (720p instead of 1080p for example). and see if this helps.
2. Using a lot of high CPU inputs such as NDI, Instant Replay and Video clips.
Try slowly closing these inputs one by one until the warning is gone.

Honestly, if you eventually manage to tell and explain that to her, she'll probably think it's cute that you were that nervous

On the contrary I'd recommend not telling her that the creepy breather on the phone was him. I can't imagine it would help his chances.

i totally agree there
sturschaedel 27
If OP really can't manage to talk to her in person or on the phone he should write a short letter along the lines of "Hi *her name*, I'm painfully shy when it comes to things like that, but here goes: I think you are beautiful and kind and I'd like to take you out on a date some time. I'll call you tomorrow. Yours, *your name*". That way he doesn't need to do the hard part on the phone, gives her a little time to make up her mind, and when he does call her the next day he basically needs to say "Hi, it's *name*" and she can do the rest of the talking.

That does suck. I'd probably text her and let her know how that it was an accident, then call her again and promptly proclaim your undying love.
Brandi_Faith 33
I don't get why everyone always encourages someone to express their undying love for someone else. That's a horrible idea in my opinion! To hear that someone is madly in love with you and has been for years when you maybe haven't even really noticed them, or talked to them, is a bit much. It's also a bit much & possibly overwhelming if you've been friends for years and don't feel the same way. In my opinion it's always best to just ask someone out on a date. You are letting them know you're interested without pressuring them or overwhelming them. That way the other person won't be freaked out, and if they turn you down or aren't interested in you then it's not as embarrassing. I think we need to stop telling people to express their "undying love" as 1) it's probably getting them turned down and feeling extremely embarrassed, 2) it can completely ruin friendships, & 3) in a lot of these cases the other person has had all those years to feel the same or pick up on signals and if they felt that way back they probably would've sent some signals back (not all cases but some). Start slow and ask for a date, there's less harm in that in my opinion.
Garnetshaddow 30
I really agree with you. People you don't know who say they're really interested are so creepy. I just had this happen at work. (I work overnights in a gym.) A regular member I do talk to texted me on behalf of his friend one night. I thought they were high and doing a prank... so I let it go. The guy then found me on FB and got my number. It was weird. I won't answer his texts anymore, removed him off the internet and I think that friend will have a word with him about propositioning girls at 5am. >< What a mess. If he'd bothered ever talking to me at work... I'd have been way less creeped out.
I was being sarcastic. By saying "proclaim your undying love, I didn't think anyone would so I put it as a joke. If you actually do call someone and creepily tell them that they're the one and you'll never get over it if they reject you, then you deserve to be rejected. I meant more like "call her back and tell her how you feel"
sweetbliss3 37
that's cute. not the part where you sound like a creeper breathing, but the rest. just try it again and explain the situation and go from there. if she's a decent girl, she'll understand. good luck.
thinblue32 15

drunkmunkey 24

the trick is to stammer out the words "how.. was.. your.. day?" and let her do the rest. most females are brilliant at conversation if they feel like.
Mauskau 35
Unless I know a person well, I can't speak to them properly in person. I'm quite shy at first, especially on the phone where I can't see them. My response to the question would be "it was alright, yours?" if that. Women at work try to start conversations with me in the toilets and I just feel so awkward I don't really answer properly.

Calling women "females" is a common tactic in degrading human women, so yeah, it's super annoying.
Sometimes I think you people got lost on your way to Tumblr. #12 is from India, and English is most likely not his native language. It's a subtle distinction that he probably doesn't know even exists. If you really cared and weren't just desperate to feel righteous, you could have politely explained to him that it sounds rude to you, rather than just going "Ugh." or "Super annoying." and assuming that he is sexist. You total weirdos.

Today I am having a hard time thinking about conflict resolution in Côte d'Ivoire. I spent Sunday-Tuesday in Bouaké, the stronghold of the Forces Nouvelles, a rebel group which is in the process of demobilizing. I spoke with community leaders about the process of rebuilding in a post-conflict environment, the politics of constructing a future when all the guns aren't put away yet. I left feeling inspired, a little more in awe of the organization I'm laboring freely for this summer.
Photo attributed to http://www.nbcconnecticut.com/news/local-beat/Massacre-in-Manchester.html
When I got back to an internet connection, a friend sent me an article about America's latest killing rampage – nine dead in a workplace shooting. The picture showed a group of people praying outside of my high school. The title read "Massacre in Manchester," my hometown in Connecticut. Although I do not know any of the victims, I find myself needing to take a moment.
Today, I'm confused and sad. I'm thinking about how Manchester was when I was growing up. I remember it being a good place to be a kid. I remember neighborhood block parties, summer days spent at the pool, little league practice, swim team, the high school homecoming parade down Main Street. I'm thinking about the contrast with this image and the way I see it now. The last time I was home, I noticed two new jail bond offices blocks from my house, my mother tells me the owner of the corner convenient store was pistol whipped, drug addicts randomly started shooting down the block, there are less families moving in, more moving out. My mom has been talking about how Manchester is changing for a while, but I never thought it had changed this much.
Before Omar Thornton, the 34-year-old shooter in Tuesday's tragedy, was called in for a disciplinary hearing and shown video footage of his theft from Hartford Distributors, he had complained to friends and family about racial harassment in the workplace. He said there were racial epithets written on the bathroom wall, and a stick figure drawn with a noose around it. He said his supervisors made racially charged comments. He called his mother after he had shot and killed eight people to say that he had taken care of the racists who were bothering him. Then he turned the gun on himself. His family and friends cannot make sense of his actions.
I got on facebook this morning to read the reactions of my community. I saw one post expressing frustration with the press "pulling the race card." Comments agreed, most saying there was no good excuse for killing eight innocent people. One comment, however, read, "Whenever they do something wrong and get caught they try to blame the white man."
I don't know the specifics of Omar Thornton's life. I do not think senseless violence is ever justified. But when I start to think about race dynamics in my town, I find it hard to just dismiss the racial overtones in the press coverage I've read. The racial composition of my town has changed substantially during my lifetime. Although my high school had failing test scores, we boasted the "highest diversity rates" in the state. If you took a walk down the hallways though, you'd quickly notice how segregated it was. Honors and AP classes were mostly white. General studies courses, on the opposite end of the spectrum, were mostly comprised of blacks and Latinos. The cafeteria was equally segregated.
This must have bothered the school because they created a mandatory class called "Race Relations." All freshmen were required to take it. My little sister still had to take it five years later when she arrived at MHS. From the way she describes her experience, it sounds about the same as I experienced it: a few clichéd videos about diversity and togetherness, one exercise where we wrote all of our races on the board and then shouted out stereotypes, white kids getting defensive about how not-racist they are, kids of color getting frustrated about how much that misses the point.
One of the few truly honest discussions I ever had about race during my time at MHS occurred at the bus stop with a kid down the street. He told me that he was sitting on his porch and a passing motorist shouted "nigger" at him. I was incredulous – that stuff still happens? He answered, all the time.
I am not trying to draw a cause-effect between the Manchester education system and the tragedy that took place this week. (Omar Thornton wasn't from Manchester, for one). But seeing pictures of the family's of the dead crying on the lawn of my high school started me on a thought flow which lead to this obvious epiphany: there is a lot of conflict in my hometown. There was more shooting in Manchester this week than there was in Bouaké.
I am realizing that there is a need for conflict resolution in my back yard. There is a need to do what I have spent my summer encouraging others to do: look to the roots of the problem. Do not adopt an "us" versus "them" attitude. Be honest. Realize that questions like, "What is happening to my town" miss the point. "Why is this happening to our town?" and "What can we do to make things better" can help us start to get there. I'm grateful for the distance that has helped me to see this.

I thought he originally did graduate from MHS? I find the whole thing very dodgy. I saw a video today of the press trying to incite race into the issue by asking "were any of the victims african american?" and getting a "no" from the police. It's hard to have african american victims at an all-white workplace, but it's going to be spun out of context. Omar was the ONLY african american working there, and there was one other Jamaican.
All reports in the beginning indicated that he used a rifle, and some papers reported police came in "with guns blazing" (all of these have been taken out of the current edited stories) and now reports are that these guys got killed by 9mm weapons… the same kind the police use, and there is no such thing as a 9mm rifle. All of that is a bit sketchy, how the story suddenly changes. No reports have come out about how he made the bare minimum the union allowed even after he should have gotten a mandatory raise, or how he didn't drink or smoke, had no criminal history and supposedly was supportive of his family. Just that he was a black guy stealing booze (which he was selling on the side, probably to make a little extra money to support the people in his life). Instead the media turns a non racial issue (the only racial issue here is that the white people gave him shit where shit wasn't deserved) into a very raciST issue.
What's interesting too is that while the AP/Honors classes were almost entirely white, the GS were almost entirely black and latino, the CP (and too a lesser extent CP) classes were fairly well-integrated and there weren't a lot of problems in the CP classes at all. The only time anything was segregated there was at the cafeteria. I think the most diverse place at MHS was the track and field team. People from all walks of life went there and it wasn't about being black or white or anything else, people just joined to compete. Oftentimes at the beginning of the season there would be more than one hundred kids on the team, and everyone except the distance runners were integrated and happy, and the distance runners (all of whom came from the Honors courses) were happy about that too. Looking back, I think it's safe to say that the problems were really caused by the white folks hanging on to outdated and frankly 'redneck' ideas, ideas that I never thought people were even taught.

NIH critic to quit Congress
Pennsylvania Rep. James Greenwood will head Biotechnology Industry Organization
Ted Agres(tedagres@lycos.com)
Rep. James C. Greenwood (R-Penn.), known for his hardball investigations into the healthcare industry, corporate scandals, and conflicts of interest at the National Institutes of Health (NIH), announced yesterday (July 22) that he will not seek re-election and instead will become president of a major biotechnology trade association when his term expires next January.
Greenwood has agreed to head the Biotechnology Industry Organization (BIO), a Washington-based trade group that represents more than 1000 companies around the world. As chairman of the House Energy and Commerce Subcommittee on Oversight and Investigations, Greenwood had spearheaded probes into financial consulting arrangements that many of these companies have with scientists and officials at the NIH, the Food and Drug Administration, and other agencies.
"It's not easy to walk away from being a congressman, and I probably wouldn't do it for any other organization," Greenwood told The Scientist yesterday. "I believe from the work I've...

If you are looking for ways to improve your business, most business owners try to look for operational improvements, however, the answer may be improving your identity through branding. Branding is not just for large companies, it is an essential way for small business to communicate with their customers what they stand for and what to expect from them. Branding shapes the way your business is perceived by the outside world.
A brand is more than just a logo or a letterhead, your brand is your corporate identity. An effective brand tells the world who you are, what you do and how you do it. Branding is a huge factor in building your credibility with prospective customers. If your brand is perceived as a premium brand you are at an advantage over your competitors as people will be prepared to pay a more for your product or service. Having a strong brand also helps you in your sales process. If you are well known and have a good reputation 80% of the work is done.
If you are positioning yourself at the high end of the market and want to portray a premium image your branding should reflect this from the actual product to the location and décor of your office.
If you are positioning your business in the high end of the market your product should be of the highest quality as people at this range of the market expect the best. On the other side, there is little benefit to your business in marketing high-quality goods at the low end of the market.
Your price should reflect the product and the market you are aiming for. Be careful when marketing low-cost goods and budget goods. Budget goods or "value" goods are at the lower end of the market, "No Frills" goods are good quality products but only provide the customer with the basics which can then be upgraded at a price.

Mario Isola: "What we are testing her...
Mario Isola: "What we are testing here is the final version of the 2020 tyres."
Cecilia Demartini

Mario Isola
Sports Pundit spoke to Pirelli head of F1 and car racing Mario Isola about the decisive post-season tyre test in Abu Dhabi on December 3-4.
This weekend, the 2019 FIA Formula One World Championship comes to an end at the Yas Marina circuit, with the Abu Dhabi Grand Prix.The 70th season of the pinnacle of motorsport has seen Briton Lewis Hamilton conquering his sixth World Drivers title at the United States Grand Prix held in Austin, Texas, on November 3.
Back in Austin, Pirelli, the exclusive tyre supplier for the FIA Formula One World, run a test with the 2020 tyres which received criticism from some of the drivers, raising doubts on the improvement of the tyres.
SP: What is the concept behind the construction of the tyres for the Formula 1 2020 season?
MI: *"The construction of the 2020 tyres aims to reduce overheating and degradation, thanks to a different profile. This will mean that we can also reduce the pressures.
"The general compound concept is to extend the working range of some of the tyres as required, so that they operate more effectively within a wider window of temperature, making it easier for the drivers to get the best use from them."*
SP: Back in Austin, when the teams had a first taste of the new package, drivers were given two sets of C4 compound 2020 tyres to be used in either session.How many sets the cars will have allocated in the post-season test in Abu Dhabi?
MI: "In total, the drivers will get 20 sets of tyres to test in Abu Dhabi, made up of both 2019 and 2020 tyres, so that they have the chance to run some valid back to back comparisons. "Pirelli will select 12 of these sets a mixture of 2019 and 2020 tyres and the teams will choose the rest themselves."
SP: Yas Marina is a completely different circuit to Austin (COTA), where the cars tested the 2020 compound. What can we expect from the official two-day test in Abu Dhabi?
MI: "As Abu Dhabi will be a test after the season, the teams will be able to run cars and set-ups optimised for the 2020 tyres, rather than focussing on a race weekend in 2019 specification which was the case in Austin," Isola explained.
He also pointed out the fact that "it is a two-day test, so the teams also have the time now to carry out a full assessment."
"Another important difference should be the weather, which will be warm in Abu Dhabi, as opposed to not far above freezing in Austin," he remarked.
SP: Can you already have a sense of how different the final version of the tyre could be to the prototypes being tested this year?
MI: "What we are testing here (Abu Dhabi) is the final version of the 2020 tyres, so what they try out here is what is planned for the races in 2020."
SP: Pirelli came back to Formula 1 in 2011, from your perspective, what evolution (technological advance) has had the most impact in the initial request to Pirelli on developing a high degradation compound?
MI: *"The brief has changed slightly from year to year, which is why we came up with the idea of a target letter to ensure that everyone was aligned on what we should be doing.
"The current emphasis is actually no longer on high degradation tyres, as it was when we first came to F1: instead, now we are creating tyres designed to allow drivers to push as hard as possible during each stint, given that the teams tend to generally favour making just one pit stop per race.*
Accordingly, the range of our tyres from year to year is never absolutely identical: we are adjusting the compounds and constructions every season to maximise the possibilities learned from all the advances in tyre technology.
"The biggest changes we have seen so far was the move to hybrid engines in 2014, then the wider tyres two years ago. In 2021 there will be an even bigger change as we go to 18-inch tyres, so it's a non-stop evolution.
Every year, F1 cars increase in performance: lap records have been reduced by up to seven or eight seconds compared to five or six years ago, so Pirelli has to deal with this by ensuring optimal grip and durability."
Rokit William Racing has recently announced its driver line-up for the two-day Pirelli test. Behind the wheel of the FW42 will be George Russell, and Nicholas Latifi, both are confirmed by the British team as its 2020 race drivers.Former Formula 2 driver Roy Nissany will join them on both testing days.
Renault F1 team has announced that Esteban Ocon will officially become a full-time driver for the team from next Monday on - Ocon signed a multi-year deal with the squad, just in time for post-season testing.The Frenchman is returning to F1 and is set to be behind the wheel of the R.S.19 in Abu Dhabi next week.

Former Whitecaps Traded at Deadline
Today the Seattle Mariners traded left-handed pitcher Jarrod Washburn to the Detroit Tigers for former Whitecap pitchers Luke French and Mauricio Robles.
"We had an opportunity to acquire two starting left-handed pitchers under the age of 23, including one with Major League experience", Seattle general manager Jack Zdurienecik said in a statement.
French has mostly played with Detroit's AAA farm club Toledo Mud Hens this season, but has had five starts with the Tigers. He is 1-2 with a 3.38 ERA in those games for Detroit. In a game against Seattle on July 23, he limited the Mariners to just two hits in 5 1/3 innings. Playing for West Michigan in 2006 and part of 2007, he was crucial in helping the 'Caps winning back to back Midwest League titles. He was named MWL Pitcher of the Week on 07/23/06. French was an eighth round pick of the Tigers in 2004, coming out of high school in Colorado. The 6'4″, 220 pound lefty, basically hurls three pitches. His fastball is 'Reagan Era' at 86-88, but can hit 90 at times. He can also toss a 76-78 mph slider and a sinking change up at around 74-76.
Robles pitched for West Michigan in 2008, and pat of this season before being promoted to High-A Lakeland. His 2008 totals are 5-3 with a 2.66 ERA in 23 games. He only gave up two home runs and struck out 79. This season in only 11 games with the 'Caps, he was 4-4 with a 4.23 ERA, and struck out 71. Robles is a bit more of an unknown, as he didn't focus on pitching until after he was signed by Detoit as a free agent out of Venezuela. His fast ball averages 91-94 and has peaked at 96. Unfortunately, it goes down to 89-90 from time to time. His arm noticably slows down and flattens during while throwing his curce, so that's something he'll have to adjust in the Minors.
Good luck to both Luke and Mauricio in this new chapter of their careers. All the best in Seattle, and we appreciate your time and efforts in the Tigers organization. Seems like 'win-win' for both teams on this one. Detroit's hold on the AL Central is hanging by a string, so hopfully Washburn and keep runs off the board, as the Tigers are having trouble scoring them.

Eine Zikkurat oder Ziqqur(r)at (auch Schiggorat, Zikkurrat und Ziggurat; babylonisch für "hoch aufragend/aufgetürmt, Himmelshügel, Götterberg") ist ein gestufter Tempelturm in Mesopotamien.

Herkunft
Die Zikkurats sind wahrscheinlich aus einer Terrasse mit einem Tempel an der Spitze entstanden. Mehrheitlich wird eine Entwicklung im südlichen Mesopotamien seit dem 5. Jahrtausend v. Chr. angenommen. Frühere Formen von Tempelterrassen bestanden jedoch neben den Zikkurats weiter. Zikkurats aus der zweiten Hälfte des 3. Jahrtausends sind auch in Elam im Südwest-Iran nachgewiesen. Ausgrabungen in der südöstlichen Gegend des Irans in der Provinz Kerman brachten in einer dort entdeckten Siedlung zwei Hügel/Terrassen (Konar Sandal A und B) ans Tageslicht, wobei es sich bei Sandal B um eine Zikkurat-Anlage aus der ersten Hälfte des dritten Jahrtausends gehandelt haben dürfte.

Verbreitung

Ungefähr 25 Ruinenstätten von Zikkurat-Bauwerken lassen sich in Mesopotamien, vor allem in Babylonien, nachweisen. Die berühmteste Zikkurat, die des Mondgottes Nanna, befindet sich in Ur auf dem Gebiet des heutigen Irak. Die Architektur einer Zikkurat ist am besten an der Zikkurat der kassitischen Residenzstadt Dur Kurigalzu nachvollziehbar, wo sich ein Zikkuratkern besonders gut erhalten hat. Auch im benachbarten Elam wurden Zikkurats erbaut, die sich dadurch von den sumerisch-babylonischen unterschieden, dass sie durch Innentreppen erschlossen wurden. Auch bautechnisch gibt es einige Besonderheiten. Der älteste Bau steht in Tappe Sialk und wird auf 2900 v. Chr. datiert, der besterhaltene in Tschoga Zanbil (elamisch Dur Untash) hat heute eine Resthöhe von 25 m (einstmals um 50 m) und eine Seitenlänge von 105 m.

Merkmale

Die Gemeinsamkeiten, die alle Zikkurate (in Babylonien, Assyrien und Elam) zeigen, sind die Stufenform (von zwei bis zu sieben solcher Stufen, sich nach oben jeweils verkleinernd) sowie ihre beiden Hauptbaukörper bestehend aus einem Mantel (Backsteine) und einem Kern (ungebrannte luftgetrocknete Lehmziegel mit Strohmattenlagen).

Ob jeweils ein Tieftempel sowie ein Hochtempel existierten, lässt sich heute nur noch schwer nachweisen. Zumindest in Babylon und Borsippa erscheint die Existenz einer solchen Zweiteiligkeit des Heiligtums seit der spätbabylonischen Zeit nachgewiesen.

 Babylon: Etemenanki (Hochtempel) – Esagila (Tieftempel)
 É-TEMEN-AN-KI – "Haus der Fundamente von Himmel und Erde"
 É-SA-GIL – "Haus des erhobenen Hauptes (Marduk)"
 Borsippa: Euriminanki (Hochtempel) – Ezida (Tieftempel)
 É-ÙR-IMIN-AN-KI – "Haus der sieben Dächer des Himmels und der Erde"
 É-ZIDA – "Haus der Wahrheit"

Zumindest bei diesen beiden Bauten scheint es sich im Fall des Hochtempels nicht um einen eigenen Tempel auf der Spitze des Turmes zu handeln, sondern um einen "aufgeklappten" Tieftempel, der vertikal alle Einzelheiten, die auch zur ebenen Erde existierten, widerspiegelt. Somit befindet sich an der Spitze des Turmes lediglich das Allerheiligste (Cella).

An den hauptsächlich rechteckigen südbabylonischen Zikkuraten wurde meist eine zentrale Mitteltreppe in Rampenform nachgewiesen. Zusätzliche und beidseitig seitliche Treppenaufgänge, an die Mitteltreppenkonstruktion angelehnt, bestanden ebenfalls. Die zeitliche Einordnung gerade dieser Hauptmerkmale erweist sich zum Teil als unmöglich, da sie zu allen Zeiten neu überbaut wurden.

Einige Zikkurate

 Ur: Zikkurat des Mondgottes Nanna
 Uruk: Zikkurat des Gottes An
 Babylon: Etemenanki
 Tschoga Zanbil: Dur-Untash
 Borsippa: Birs Nimrud
 Harran: Ehulhul, Zikkurat des Mondgottes Sin
 Assur: Anu-Adad-Tempel, eine Doppelzikkurat

Nachwirkung
Nach verbreiteter Ansicht ist das schraubenförmige Minarett der Moschee von Samarra nach dem Vorbild der Zikkurat erbaut worden. Als Beispiel einer Zikkurat mit einer äußeren Wendelrampe ist der Turmbau von Khorsabad anzuführen. Wie im Fall der siebenstöckigen quadratischen Zikkurat von Khorsabad für die altorientalische Zeit nachgewiesen, gelangt man zur Spitze des Minarett ebenfalls über eine spiralförmige Außenrampe.

Sonstiges
Die biblische Überlieferung des Turmbaus zu Babel geht nach heutiger Erkenntnis auf einen solchen Bau zurück. Die frühsumerische Dichtung Enmerkar und der Herr von Aratta erwähnen ebenfalls eine Sprachverwirrung in Zusammenhang mit großen Bauvorhaben.

Dubai plant gegenwärtig unter der Bezeichnung Zikkurat die Entwicklung einer neuen Art von riesiger Wohnpyramide. Federführend ist die in Dubai angesiedelte Firma für Umweltdesign Timelink.

22,000 Pakistani students enrolled in Chinese universities: ambassador
A memorandum of understanding (MoU) between President of China Foreign Affairs Studies University and Pakistan's Foreign Service Academy, Ministry of Foreign Affairs
BEIJING: Approximately 22,000 students from Pakistan are studying in various universities in China, Pakistan's Ambassador to China Masood Khalid said.
The students, enrolled in different fields of education, will serve as a bridge between two countries, he said during the signing of a memorandum of understanding (MoU) between a Chinese university and Pakistan's Foreign Service Academy, Ministry of Foreign Affairs.
The MoU was signed by Ambassador Khalid and President of China Foreign Affairs Studies University, Qin Yaqing.
Both sides called for collaboration in research, and exchange of students, academic researchers and think tanks.
Speaking with Geo News, Khalid said that Pakistan and China are already working together in different fields such as energy, infrastructure, industrial parts and Gwadar port development, and the MoU will now mutually benefit both countries in the sectors of education and science.
The university's president showed a keen interest in enrolling Pakistani students.
"This collaboration is very important for us and we give very special attention the training of students from Pakistan, especially after the China Pakistan Economic Corridor," he said.
A young Pakistani diplomat Malik Zulfiqar, said that studying at the university will help in learning Chinese language, culture and tradition, which will be good for the career of students.
Zulfiqar and four other individuals from the Foreign Service Academy are undergoing training at the university.

In September 2017 I ordered and received my ThinkPad X1 Carbon 5th gen laptop. So far I have found the computer to be outstanding, with one enormous and seriously troubling flaw: the trackpad / touchpad mouse. While I have not had the issues with the mouse/arrow suddenly disappearing or freezing, I have found the trackpad to be incredibly tempermental. For example, when working in Word with tables and you attempt to widen or narrow the width of columns, it is incredibly difficult to easily position the mouse/cursor over the bars of the columns. Using the trackpad, the pointer will stop moving as you move your finger across the trackpad, but then you move your finger just the slightest bit more, and it moves right over the place where you want the arrow/cursor to be. For example, if I roll my finger tip left or right (not move it, just roll the tip of my finger) the cursor will sometimes respond and other times will not. It is this gentle rolling that is needed to get the cursor in just the right spot sometimes - but no, not with this laptop. This is a problem in every application i've used thus far and it makes the computer absolutely inferior to my last ThinkPad (T430S) which had an oustanding trackpad that was easy to maneuver and very friendly to the touch.
I have loaded all the latest drivers for the computer and specific ones for the touchpad, but they have not resolved this problem. I am a professor at a university and if I could throw this laptop out the window and start over again, I would. However, my university frowns on this and I will probably be stuck with this otherwise great laptop for the next 3 years. How can Lenovo charge $1800 for this laptop (my specs: i7-7600 CUP @ 2.80GHz 2.90GHz RAM 8.00GB, 64-bit.
I have the exact same problem. I've had the trackpad and motherboard replaced to no avail. Lenovo neither recognise this problem nor care.

Machine Guns, Police, Illegal Behavior And Inadequate Training
Coloradoan.com:
The embattled Berthoud police department bought fully automatic military-grade machine guns, hired officers who showed "glaring" signs of illegal and inappropriate behavior, and then gave them "woefully inadequate" training, Larimer County Sheriff Justin Smith says.
In a letter sent to town officials and made public Tuesday night, Smith offers a scathing critique of the department, which has come under fire for child-abuse allegations leveled against one of its officers. That officer was arrested, and Police Chief Glenn Johnson resigned amidst allegations he knew about the accusations against his officer but did nothing.
Since October, Smith's deputies have been serving as the town's police force at officials' request.
In his letter, Smith said the department was rife with mismanagement, from poorly handled evidence, paperwork and personnel files to broken Tasers and in-car laptops. He said problems within the department risked breaking the trust between the public and law enforcement, and risked letting criminals go unprosecuted because court documents weren't being filed on time."Most shockingly, fully automatic machine guns (not appropriate for standard police operations) were acquired from the military and were stored in open room with minimal security," Smith wrote. "At the Berthoud Police Department, we found that the chief has overlooked and neglected many of the things that are absolutely necessary to leading an effective and accountable police operation."
"The application and hiring process for town officers allowed unqualified individuals to be hired and to maintain employment, despite glaring warning signs of inappropriate and sometimes illegal behavior," Smith wrote to the town. "Paperwork filing appeared to be haphazard at best. The chief did not maintain appropriate personnel files on his officers, yet he had documents in town filing cabinets from his previous employment. Those files should have never left those agencies."
Police officer Jeremy Yachik was fired by the town in October after he was arrested on child-abuse charges after video surfaced of Yachick allegedly beating his daughter.
Good grief. And they say that we're unqualified to own fully automatic firearms. Perhaps rather than repealing the Hughes amendment (itself an obscene abomination) as I have advocated, we ought to insist that it be repealed for us and applied exclusively to law enforcement.
These guys were just a dangerous hazard top to bottom.

Skin Deep is a five-part series in which The Swaddle explores how women's self-image, ideas about and efforts toward beauty change with age. Each month we will feature the responses of a woman from a different decade of life. This month we speak to Arti Chada, a 57-year-old homemaker who lives in New Delhi.
Arti Chada: Yes, inside out!
AC: Yes, I think so.
AC: Not much. Maybe just a few hours in the week. I can say I spend more time [now] and make more effort towards grooming and looking good because, simply put, I have more time on hand. Because the children have grown up, I have less responsibilities. When I meet my college friends, they always tell me that we remember you as the one who wore the best salwar kameezes to college. This is something I find very odd, because for me, dressing up was something that came naturally. Looking good and dressing well was something I never had to make an effort for. But now, I think you have to look after yourself more at this age, and you need to be a little more conscious about grooming yourself. I have more time to read about it, and experiment on myself. I never did it [before] at all. I used to hardly go to parlors and things like that, because I just never had the time.
AC: I don't get troubled, I just make sure to prioritize and make the time! I don't like to ignore that. [In the past] we were posted in places where it was difficult to get domestic help, I needed to be a hands-on mom and a hands-on homemaker, and [focus on] what I was doing, which was working with NGOs. I had virtually no time to even do things that I would — I've always enjoyed dressing up.
AC: My two pregnancies! I think the main reason could be that while I was pregnant, I was indulged in more. When you're indulged in more, you feel more loved, more cared for. You're eating better, you're getting better looked after, your skin is glowing. You are taking caring of yourself, maybe because there is another person you are responsible for. So maybe indirectly that becomes the reason why you feel beautiful inside out. If somebody asks me 'Which part of your life do you want to go back to?' I would say being pregnant. Not after pregnancy, that was the most harrowing.
AC: Appreciation from friends and family. I think I look my age, but there are many around me who feel that I have kept myself, so to say, inverted commas, much better than other women our age would have. And [my daughter]. Normally daughters are not the ones who go around appreciating moms all the time; maybe after a certain age. But she makes it a point to point out what she feels looks good on me, doesn't good on me, and appreciate how I look. All that makes me feel really good and really happy, that somebody who's so much younger would even notice all that on an older woman.
This interview has been condensed and edited for clarity. As told to Urvija Banerji.

Halladay handcuffs the Cardinals
By Craig CalcaterraMay 6, 2010, 5:10 PM EDT
Roy Halladay is now 6-1 after stifling the Cardinals over seven innings in the Phillies 7-2 win. He worked out of early trouble and struck out nine while scattering — yes, scattering! — eight hits.
Best moment of the game. Seventh inning, Roy Halladay already has thrown 117 pitches and has just given up an RBI single to Pujols. Charlie Manuel comes out to the mound to take the ball. Except he doesn't. We'll learn later what Halladay actually said, but he effectively told Manuel that he wasn't leaving the game. Matt Holliday grounds out on the very next pitch and Halladay leaves the field to the roar of the crowd. Robin Roberts tribute anyone?
By the way, the above photo was taken this afternoon by Matt Slocum of the Associated Press. It's one of my favorite game shots of the year so far. It pretty much captures the "I'm gonna handle this myself" essence of Halladay.


Last night, I arrived in San Francisco for a series of meetings and the AGU (American Geophysical Union) fall meeting. I'm staying at a bargain priced (but very nice!) hotel only about ½ mile from Moscone and about 50' from the beginning of the Powell St. cable car line. Lots of people and lots of cars everywhere. This morning, I walked up and down streets, had dim sum in Chinatown, wandered through bookstores and camera shops and ending up with 0.01 mile more than I logged yesterday. The most annoying thing about walking around here are the number of people smoking while they are strolling down the sidewalk. It seems that 20% of the people in San Francisco must smoke, or at least that's the way it feels. You can see layers of smoke hanging over the sidewalks. Or at least those that hang around downtown. It was much nicer last night when it was raining i.e. not as many smokers walking in the rain. According to the weather guessers, it is supposed to be raining most of the week.
Monday evening - First "official" day of the AGU and there are way too many presentations. The planetary science ones are always interesting as are the ones on climate change but this afternoon, I attended a series of presentations in the Education track on "Using Web 2.0 Technologies to Facilitate Science Communications". Pretty interesting presentations and discussions. Everyone seems to be so passionate about what they are doing. Quite a change from the administrative side of the university that I usually see. This is one of the reasons for setting up the podcasting capabilities in Barrow and yesterday, several of the researchers had additional things they would really like to see. I think I'm going to be busy.
I started listening to this audiobook on the flight down and got totally sucked in. I listened whenever I walk around over the weekend and last night, I ended up listening well into the wee hours and finished it up this morning. Excellent book. Earlier this month, it was being offered as a free download but it is no longer available.
I wasn't envious when you were locked up in that barren snow laden land up north, but now I'm envious. Enjoy your trip. I also dislike smokers and their infringement upon your personal space.
It has been a few years since we were down in SF. We stayed around the corner from Union Square and took the trolley to Ghirardelli square. The street cars were always full.
Thank you for stopping by. Unfortunately, I don't have any riding opportunities down here. In fact, I'm kind of surprised that I haven't seen a single bike on the road. Several scooters parked and locked up but none on the road.
I don't think I will be taking the trolley cars anywhere, too many meetings scheduled some not ending until 10 pm.
Ok, I know this is reaching for it, but are you going to have Rice A Roni while you're there riding on the street cars?
"Land of the Noon Moon"


Someone's been hacking the bark from acacia trees in Manoa Valley District Park.
And while the culprits have not been caught, some residents have identified a motive — a lively market in Hawaiian acacia bark, which reportedly can send you on a spiritual psychedelic journey.
"I want to give thanks and praise for helping us mere mortals achieve inner heights!!" a customer wrote on a website for one acacia purveyor on Oahu.
No one knows for sure whether the Manoa Park hackers are using it themselves or selling it. Or perhaps the attacks are the random acts of tree haters — though that seems odd, considering only the acacias have been targeted and the bark is not left on the ground.
Damaged acacia trees at Manoa Park.
"I would assume they're trying to sell it," said Angela Richards Dona, a Manoa resident who's been researching it with her husband Alessandro.
Alessandro first noticed people messing with the tree bark about a year ago. The species, Acacia confusa, is native to Southeast Asia, but has invaded much of the tropical Pacific.
The people Alessandro saw the first time were using something small, like a knife or pick, to take little pieces of bark.
In December or so, Manoa residents started noticing much larger gashes in the tree trunks that looked like they had been hacked by a machete. The six or so trees that have been damaged are in an isolated strip of the park mostly frequented by joggers and dog-walkers during the day.
The hackers, at least recently, appear to be working only at night.
Residents notified the Honolulu Department of Parks and Recreation, which put notices on the trees reminding people that it's against city regulations to deface a tree.
"It is strange for people to be scraping the bark off of trees," said parks spokesman Nathan Serota. Park employees could only recall one other incident of tree molestation many years ago at Keehi Lagoon Beach Park.
"We really want to discourage it because it's not good for the tree," Serota said.
Tree wounds don't heal. Instead, the tree cuts off nutrients to the damaged part, making it susceptible to funguses and pests, leading to decay. Enough structural damage and the tree poses a danger to passersby and must be cut down, Serota said.
The Honolulu Parks Department posted signs in January warning against stripping bark from acacia trees at Manoa Park.
The signs the department posted in mid-January seem to be having some effect. There was a little more bark-stripping right after that, but since then it has stopped. The parks department plans to monitor the trees and take steps to prevent decay.
A message left on the website Wednesday afternoon was not returned.
A website that offers acacia bark from Taiwan has this to say about its connection to ayahuasca, a psychedelic substance used in South American spiritual ceremonies.
The bark contains a substance with a long chemical name, abbreviated as DMT. Its legality is murky. Several websites say that eBay banned sales of acacia bark in 2017.
Whatever its properties, many Manoa residents want whoever's been stripping the bark to knock it off.
Sorry. That's an invalid e-mail.
Thanks! We'll send you a confirmation e-mail shortly.

More households will be pushed into fuel poverty without 'radical action' by the Government because of higher energy prices and growing unemployment, a new report has warned.
The Government's Fuel Poverty Advisory Group said a clear plan should be set out to meet the target of eradicating fuel poverty by 2016. Fuel poverty levels were more than three times the rate of five years ago and existing measures were inadequate to deal with the scale of the problem, said the report.
Derek Lickorish, chairman, said: "Energy prices are going to become even more of an issue as the cost of tackling carbon emissions grows, unemployment rises and the energy market remains volatile. The measures in place to deal with fuel poverty now are simply inadequate to tackle the rise in fuel poverty that this cocktail of issues could create.
"Unless fuel poverty is tackled head on, many hundreds of thousands more vulnerable pensioners, families and disabled people will struggle to afford their energy bills. A thorough strategy, with decisive action on social tariffs and energy efficiency, is needed from the Government to help lift the poorest households out of fuel poverty."
The group estimated that over four million households in England were in fuel poverty - where more than 10 per cent of a household income is spent on energy.
David Kidney, Energy and Climate Change Minister, said: "The Fuel Poverty Advisory Group report makes a valuable contribution to our work looking at fuel poverty policies and programmes. Their input now and through the year is welcomed by DECC (Department of Energy and Climate Change) as we continue to work to tackle the very real challenge of fuel poverty.
"Government has spent more than £20 billion since 2000 on policies and programmes which can help tackle fuel poverty. But we know the challenge needs further action, and recognise that rising energy costs has reversed the downward trend on the number of households in fuel poverty.
"The transition to a low-carbon energy supply will also impact on consumers. We will be doing all we can to ease the burden on low-income households and provide the support required to be able to heat and power their homes at an affordable cost."

Screw theory is the algebraic calculation of pairs of vectors, such as forces and moments or angular and linear velocity, that arise in the kinematics and dynamics of rigid bodies.  The mathematical framework was developed by Sir Robert Stawell Ball in 1876 for application in kinematics and statics of mechanisms (rigid body mechanics).

Screw theory provides a mathematical formulation for the geometry of lines which is central to rigid body dynamics, where lines form the screw axes of spatial movement and the lines of action of forces.  The pair of vectors that form the Plücker coordinates of a line define a unit screw, and general screws are obtained by multiplication by a pair of real numbers and addition of vectors.

An important result of screw theory is that geometric calculations for points using vectors have parallel geometric calculations for lines obtained by replacing vectors with screws.  This is termed the transfer principle.

Screw theory has become an important tool in robot mechanics, mechanical design, computational geometry and multibody dynamics.
This is in part because of the relationship between screws and dual quaternions which have been used to interpolate rigid-body motions. Based on screw theory, an efficient approach has also been developed for the type synthesis of parallel mechanisms (parallel manipulators or parallel robots).

Fundamental theorems include Poinsot's theorem (Louis Poinsot, 1806) and Chasles' theorem (Michel Chasles, 1832). Felix Klein saw screw theory as an application of elliptic geometry and his Erlangen Program. He also worked out elliptic geometry, and a fresh view of Euclidean geometry, with the Cayley–Klein metric. The use of a symmetric matrix for a von Staudt conic and metric, applied to screws, has been described by Harvey Lipkin. Other prominent contributors include Julius Plücker, W. K. Clifford, F. M. Dimentberg, Kenneth H. Hunt, J. R. Phillips.

Basic concepts

A spatial displacement of a rigid body can be defined by a rotation about a line and a translation along the same line, called a screw displacement.  This is known as Chasles' theorem.  The six parameters that define a screw displacement are the four independent components of the Plücker vector that defines the screw axis, together with the rotation angle about and linear slide along this line, and form a pair of vectors called a screw.  For comparison, the six parameters that define a spatial displacement can also be given by three Euler angles that define the rotation and the three components of the  translation vector.

Screw
A screw is a six-dimensional vector constructed from a pair of three-dimensional vectors, such as forces and torques and linear and angular velocity, that arise in the study of spatial rigid body movement.  The components of the screw define the Plücker coordinates of a line in space and the magnitudes of the vector along the line and moment about this line.

Wrench
The force and torque vectors that arise in applying Newton's laws to a rigid body can be assembled into a screw called a wrench.  A force has a point of application and a line of action, therefore it defines the Plücker coordinates of a line in space and has zero pitch.  A torque, on the other hand, is a pure moment that is not bound to a line in space and is an infinite pitch screw.  The ratio of these two magnitudes defines the pitch of the screw.

Twist
A twist represents the velocity of a rigid body as an angular velocity around an axis and a linear velocity along this axis.  All points in the body have the same component of the velocity along the axis, however the greater the distance from the axis the greater the velocity in the plane perpendicular to this axis.  Thus, the helicoidal field formed by the velocity vectors in a moving rigid body flattens out the further the points are radially from the twist axis.

The points in a body undergoing a constant screw motion trace helices in the fixed frame.   If this screw motion has zero pitch then the trajectories trace circles, and the movement is a pure rotation.  If the screw motion has infinite pitch then the trajectories are all straight lines in the same direction.

Algebra of screws
Let a screw be an ordered pair

where  and  are three-dimensional real vectors.  The sum and difference of these ordered pairs are computed componentwise.  Screws are often called dual vectors.

Now, introduce the ordered pair of real numbers â = (a, b) called a dual scalar.  Let the addition and subtraction of these numbers be componentwise, and define multiplication as

The multiplication of a screw S = (S, V) by the dual scalar â = (a, b) is computed componentwise to be,

Finally, introduce the dot and cross products of screws by the formulas:

which is a dual scalar, and

which is a screw. The dot and cross products of screws satisfy the identities of vector algebra, and allow computations that directly parallel computations in the algebra of vectors.

Let the dual scalar ẑ = (φ, d) define a dual angle, then the infinite series definitions of sine and cosine yield the relations

which are also dual scalars. In general, the function of a dual variable is defined to be f(ẑ) = (f(φ), df′(φ)), where df′(φ) is the derivative of f(φ).

These definitions allow the following results:
  Unit screws are Plücker coordinates of a line and satisfy the relation
   Let ẑ = (φ, d) be the dual angle, where φ is the angle between the axes of S and T around their common normal, and d is the distance between these axes along the common normal, then
  Let N be the unit screw that defines the common normal to the axes of S and T, and ẑ = (φ, d) is the dual angle between these axes, then

Wrench
A common example of a screw is the wrench associated with a force acting on a rigid body.  Let P be the point of application of the force F and let P be the vector locating this point in a fixed frame.  The wrench W = (F, P×F) is a screw.  The resultant force and moment obtained from all the forces Fi, i = 1,...,n, acting on a rigid body is simply the sum of the individual wrenches Wi, that is

Notice that the case of two equal but opposite forces F and −F acting at points A and B respectively, yields the resultant

This shows that screws of the form

can be interpreted as pure moments.

Twist
In order to define the twist of a rigid body, we must consider its movement defined by the parameterized set of spatial displacements, D(t)=([A(t)],d(t)), where [A] is a rotation matrix and d is a translation vector.  This causes a point p that is fixed in moving body coordinates to trace a curve P(t) in the fixed frame given by,

The velocity of P is

where v is velocity of the origin of the moving frame, that is dd/dt.  Now substitute p =  [AT](P − d) into this equation to obtain,

where [Ω] = [dA/dt][AT] is the angular velocity matrix and ω is the angular velocity vector.

The screw

is the twist of the moving body.  The vector V = v + d × ω is the velocity of the point in the body that corresponds with the origin of the fixed frame.

There are two important special cases: (i) when d is constant, that is v = 0,  then the twist is a pure rotation about a line, then the twist is

and (ii) when [Ω] = 0, that is the body does not rotate but only slides in the direction v, then the twist is a pure slide given by

Revolute joints
For a revolute joint, let the axis of rotation pass through the point q and be directed along the vector ω, then the twist for the joint is given by,

Prismatic joints
For a prismatic joint, let the vector v pointing define the direction of the slide, then the twist for the joint is given by,

Coordinate transformation of screws
The coordinate transformations for screws are easily understood by beginning with the coordinate transformations of the Plücker vector of  line, which in turn are obtained from the transformations of the coordinate of points on the line.

Let the displacement of a body be defined by D = ([A], d), where [A] is the rotation matrix and d is the translation vector.  Consider the line in the body defined by the two points p and q, which has the Plücker coordinates,

then in the fixed frame we have the transformed point coordinates P = [A]p + d and Q = [A]q + d, which yield.

Thus, a spatial displacement defines a transformation for Plücker coordinates of lines given by

The matrix [D] is the skew-symmetric matrix that performs the cross product operation, that is [D]y = d × y.

The 6×6 matrix obtained from the spatial displacement D = ([A], d) can be assembled into the dual matrix

which operates on a screw s = (s.v) to obtain,

The dual matrix [Â] = ([A], [DA]) has determinant 1 and is called a dual orthogonal matrix.

Twists as elements of a Lie algebra
Consider the movement of a rigid body defined by the parameterized 4x4 homogeneous transform,

This notation does not distinguish between P = (X, Y, Z, 1), and P = (X, Y, Z), which is hopefully clear in context.

The velocity of this movement is defined by computing the velocity of the trajectories of the points in the body,

The dot denotes the derivative with respect to time, and because p is constant its derivative is zero.

Substitute the inverse transform for p into the velocity equation to obtain the velocity of P by operating on its trajectory P(t), that is

where

Recall that [Ω] is the angular velocity matrix.  The matrix [S] is an element of the Lie algebra se(3) of the Lie group SE(3) of homogeneous transforms.  The components of [S] are the components of the twist screw, and for this reason [S] is also often called a twist.

From the definition of the matrix [S], we can formulate the ordinary differential equation,

and ask for the movement [T(t)] that has a constant twist matrix [S].  The solution is the matrix exponential

This formulation can be generalized such that given an initial configuration g(0) in SE(n), and a twist ξ in se(n), the homogeneous transformation to a new location and orientation can be computed with the formula,

where θ represents the parameters of the transformation.

Screws by reflection
In transformation geometry, the elemental concept of transformation is the reflection (mathematics). In planar transformations a translation is obtained by reflection in parallel lines, and rotation is obtained by reflection in a pair of intersecting lines. To produce a screw transformation from similar concepts one must use planes in space: the parallel planes must be perpendicular to the screw axis, which is the line of intersection of the intersecting planes that generate the rotation of the screw. Thus four reflections in planes effect a screw transformation. The tradition of inversive geometry borrows some of the ideas of projective geometry and provides a language of transformation that does not depend on analytic geometry.

Homography
The combination of a translation with a rotation effected by a screw displacement can be illustrated with the exponential mapping. This idea in transformation geometry was advanced by Sophus Lie more than a century ago. Even earlier, William Rowan Hamilton displayed the versor form of unit quaternions as exp(a r)= cos a + r sin a. The idea is also in Euler's formula parametrizing the unit circle in the complex plane.

Since ε2 = 0 for dual numbers, exp(aε) = 1 + aε, all other terms of the exponential series vanishing.

Let F = {1 + εr : r ∈ H}, ε2 = 0.
Note that F is stable under the rotation q → p −1 qp and under the translation
(1 + εr)(1 + εs) = 1 + ε (r + s) for any vector quaternions r and s.
F is a 3-flat in the eight-dimensional space of dual quaternions. This 3-flat F represents space, and the homography constructed, restricted to F, is a screw displacement of space.

Let a be half the angle of the desired turn about axis r, and br half the displacement on the screw axis. Then form z = exp((a + bε)r ) and z* = exp((a − bε)r). Now the homography is

The inverse for z* is

so, the homography sends q to

Now for any quaternion vector p, p* = −p, let q = 1 + pε ∈ F   where the required rotation and translation are effected.

William Kingdon Clifford initiated the use of dual quaternions for kinematics, followed by Aleksandr Kotelnikov, Eduard Study (Geometrie der Dynamen), and Wilhelm Blaschke. However, the point of view of Sophus Lie has recurred.
In 1940, Julian Coolidge described the use of dual quaternions for screw displacements on page 261 of A History of Geometrical Methods. He notes the 1885 contribution of Arthur Buchheim. Coolidge based his description simply on the tools Hamilton had used for real quaternions.

Evidently the group of units of the ring of dual quaternions is a Lie group. A subgroup has Lie algebra generated by the parameters a r and b s, where a, b ∈ R, and r, s ∈ H. These six parameters generate a subgroup of the units, the unit sphere. Of course it includes F and the 3-sphere of versors.

Work of forces acting on a rigid body
Consider the set of forces  F1, F2 ... Fn act on the points X1, X2 ... Xn in a rigid body. The trajectories of Xi, i = 1,...,n  are defined by the movement of the rigid body with rotation [A(t)] and the translation d(t) of a reference point in the body, given by

where xi are coordinates in the moving body.

The velocity of each point Xi is

where ω is the angular velocity vector and v is the derivative of d(t).

The work by the forces over the displacement δri=viδt of each point is given by

Define the velocities of each point in terms of the twist of the moving body to obtain

Expand this equation and collect coefficients of ω and v to obtain

Introduce the twist of the moving body and the wrench acting on it given by

then work takes the form

The 6×6 matrix [Π] is used to simplify the calculation of work using screws, so that

where

and [I] is the 3×3 identity matrix.

Reciprocal screws
If the virtual work of a wrench on a twist is zero, then the forces and torque of the wrench are constraint forces relative to the twist.  The wrench and twist are said to be reciprocal, that is if

then the screws W and T are reciprocal.

Twists in robotics
In the study of robotic systems the components of the twist are often transposed to eliminate the need for the 6×6 matrix [Π]  in the calculation of work.  In this case the twist is defined to be

so the calculation of work takes the form

In this case, if

then the wrench W is reciprocal to the twist T.

An abstract art quilt for sale. This wall hanging has bright colors on a black background.
As I was creating it, my working title was color explosion, as I imagined the colors exploding over you. But as it progressed the images reminded me of Dr. Seuss, so it's title was changed to "Seuss Over Youse".
It's an original art quilt with a touch of whimsy but it wasn't intended for a child's room. It is an abstract that would provide a punch of color, a great focal point.
The wonky shapes and free motion quilting is unique, it's free form and used as an element of the design. It rectangular shape has bold color, blue, red and yellow.
It measures 21″ by 30″.


We arrived and the person at reception didn't speak or understand any English so there was some confusion at 1st. The problem was quickly resolved . It was fine we were just there for the night and left early in the morning for I flight. I didn't love it, but I didn't hate it either.
