An DIY RF decibel (or power) meter is an indispensable instrument in any radio workshop. Unfortunately, accurate, wideband models are fairly expensive, and home-constructed ones are generally not sufficiently sensitive and/or are very temperature-dependent. These drawbacks are overcome by a device from Analog Devices which has recently become available: a low-cost DC–500 MHz, 92 dB logarithmic amplifier that enables an accurate, not too expensive RF decibel meter to be constructed.
A few small modifications make the meter also suitable for low frequency measurements.
The circuit diagram of the decibel meter in Figure 1 stands out by its simplicity, which is due to the Type AD8307 monolithic demodulating logarithmic amplifier, IC1, from Analog Devices.
The measurand (quantity to be measured) is applied to pin 8 (INP) of IC1 via input socket K1 and capacitor C1. The capacitor ensures that no direct voltage can reach the IC. The second input of the IC, pin 1 (INM) is linked to the earth line via capacitor C4. The values of C1 and C4 are chosen to give a lower limit of the frequency range below 100 kHz.
Resistors R1 and R2 ensure that the input impedance of the meter is the usual value in RF equipment of 50 Ω. A parallel network is used to minimize any parasitic properties of the resistors. It is recommended to use SMT (surface mount technology) resistors.
The output of IC1 is essentially a current that causes a potential dropacross a 12.5 kΩ internal resistor which is available at output pin 4. Resistors series network R6-P1 is in parallel with the internal resistance to modify the scale factor, which is 25 mV dB–1 in the absence of an external circuit.
Capacitor C5 averages the output signal to ensure a stable display. Its value depends on the application: a larger capacitance gives a more stable, but slow, display; a smaller value is recommended for fast sweeping.
Preset P2 permits parallel shifting of the characteristic to give an attenuation of up to 14 dB or an amplification of up to 26 dB between the input socket and pin 8 of IC1, provided that R5 = 0. Resistor R5 provides a narrowing of this preset range.
The display may be a digital multimeter, but, although this is accurate, it is not easily calibrated.
A moving coil metering network with series resistor R7 facilitates recognizing any drift such as encountered, for instance, during calibration, but does not make reading it easy.
Measurements with sweep frequencies can, of course, be displayed on an oscilloscope. The decibel meter outputs a direct voltage that is directly proportional to the input signal. The display is calibrated in dBμ (decibel referred to 1 microvolt). The scale factor is 100mV dB–1, so that an input signal of 100 dBμ results in an output voltage of 1 V.
The meter circuit is best built on the printed circuit board shown in Figure 2, but this is not available ready made. As mentioned earlier, some of the components should be SMDs (surface mount devices) as specified in the components list. If the circuit is constructed on prototyping board, standard components may, of course, be used. Keep all wiring as short as possible, however.
If operation up to 30 MHz only is needed, IC1 may be inserted in a socket, but for use at higher frequencies the circuit should be soldered directly on to the board. This is best done after all other components have been fitted and the board has been checked thoroughly. This measure is to protect the AD8307, since this is not a cheap component.
Since the meter is an RF unit, it is clear that it should be fitted in an earthed metal enclosure. The power supply should, of course, not be fitted in the same enclosure. Another important aspect is that the 9–15 V supply voltage should be 'clean'. It is advisable to use feedthrough capacitors at the power line inputs and measurement output.
The meter circuit should be calibrated with a suitable RF signal generator or, in an emergency, an AF signal generator with calibrated attenuator. Apply a signal at a frequency of 10 MHz and a level of 60 dBμ (1 mV r.m.s.) to the input of the meter circuit. Using a digital multimeter, measure the voltage at pin 3 of IC3, increase or reduce the output of the signal generator by exactly 10 dB and turn P1 to cause a change in the multimeter reading of 100 mV. The absolute value of the output voltage is not significant.
Next, apply a signal at a level of exactly 60 dBμ to pin 8 of IC1 and turn P2 until the meter indicates 600 mV. If the requisite equipment is available, the calibration process can be repeated at a number of frequencies for greater versatility of operation.
If a signal generator is not to hand, adjust P1 until the resistance between its wiper and earth is 1383 Ω measured with a digital multimeter. Finally, adjust P2 to obtain a voltage of 1.627 V at pin 5 of IC1, again measured with a digital multimeter.

Eighty-four years have passed since this recipe was last produced. We are proud to declare the renaissance of "Amaro delle Sirene". Our flagship amaro is based on an infusion of 30 selected roots and herbs highlighting eucalyptus, ripe fruit and licorice, with a scent of gentian lutea, chicory and chamomile. Our Sirene is matured for 12 months in 250-liter French oak barrels, provided by the Marisa Cuomo Winery of the Amalfi Coast.


Winter clothing is more expensive, at just the time when we have least money to spare – extra heating costs and Christmas on the way can wreak havoc with our budget. Here are a few tips to help you stay on top of the budget in the chilly months.
Work the percentages – financial planners say you should spent between 4-6% of your take home pay, benefits or grant allowance on clothing. Allow for cleaning clothes in that amount, and if you fall in love with an amazing coat that has to be dry-cleaned you have to include in the budget enough to get your coat cleaned as often as necessary.
Start with work – if you have to spend a certain amount on your career clothing, subtract that from the budget because it's essential. What's left is what you have as 'discretionary spend', the free money you can use as you choose. A job with a uniform obviously gives you much more scope to buy casual clothing!
Check your goals – if you're saving to buy a motorbike or your own home, that probably takes priority over clothes, but there may be ways that you can combine the expenditure. A bike requires a good set of leathers or protective clothing … when you buy a jacket, why not make sure it's a classic style and bike-appropriate – that way you won't have extra expenditure once you get the bike itself.
Shop as a collective – get together with friends to take advantage of offers like free delivery over a certain amount or special offers such as three for the price of two, and split the savings between you.

Washington Road Usage Charge Test Drive Now Complete
February 8, 2019 September 12, 2019 webmaster
Transportation Commission Office – PO Box 47308 – Olympia, WA 98504-7308
Contact: Reema Griffith, Transportation Commission Executive Director, 360-705-7070
Washington volunteers tested a variety of mileage reporting methods during the 12-month pilot; next up is final analysis and reporting
OLYMPIA – More than 2,000 drivers across Washington have turned in the keys and wrapped up their participation in the year-long Washington Road Usage Charge Pilot Project. The test-driving phase of the pilot began in February 2018 and over the course of 12 months, volunteers had the opportunity to test low-tech to high-tech options for recording miles driven, as well as multiple opportunities to share feedback about their experience.
"It's rare to have such a hands-on experience to test a potential new way to fund our transportation system. I'm thankful to our volunteers for their participation and dedication in helping inform the future of transportation in our state," said Joe Tortorelli, chair of the WA RUC Steering Committee and member of the Washington State Transportation Commission that is leading this project. "We look forward to learning more about the results from the pilot test drive, which will influence the commission's final report and recommendations to the governor, legislature and U.S. Department of Transportation."
The pilot's primary goal was to test a potential new system to replace Washington's gas tax, as cars become more and more fuel efficient. Additionally, the project was designed to ensure a variety of ways for participants to record miles – from low-tech to high-tech reporting methods – as well as to enable active feedback from participants on their experience. Participants were able to choose one of five methods to record their miles and were asked to periodically review mock invoices that compared how much they would pay under a road usage charge system compared to the current gas tax.
Collectively, the project's 2,000-plus test drivers reported 16 million miles driven statewide, sent in over 1,000 emails or phone calls and participated in three surveys. Participants sounded off on a variety of topics including privacy and data collection, compliance and administrative costs, fairness and equity, travel between states, and operational viability.
With the test-driving phase complete, the WSTC will work with the WA RUC Steering Committee to review and analyze the data and volunteer feedback collected during the pilot. Findings and recommendations will be presented to the governor, legislature and USDOT in early 2020.

Q: Measuring entropy for event sequences? In TraMineR the function seqient() for calculating the entropy of a sequence object is not available for event sequences (as defined with seqecreate()). Does this mean that measures of "variation" does not make logical sense for event sequences? Are there alternatives to measures such as entropy, complexity, and turbulence for event sequences?
A workaround would naturally be to use the TSE_to_STS() function in TraMineRextras to convert the event sequence to an STS sequence object, after which functions such as seqient() becomes available. However, would the statistics coming out of this be reliable?

A: The entropy of a sequence measures the diversity of the elements in the sequence. It is computed from the frequencies of each element of the alphabet in the sequence.
For state sequences, these frequencies give the total time spent in each state belonging to the alphabet.
For event sequences, you can consider the frequencies of the events and the entropy would then give the diversity of the events in the sequence.
I illustrate here how you could compute the entropy of the events occurring in each sequence, using the actcal.tse data provided by TraMineR.
library(TraMineR)
data(actcal.tse)
seqe <- seqecreate(actcal.tse)

## first we take out parentheses and time information
## from the character representation of event sequences
tmp <- as.character(seqe)
open <- "("
close <- ")"
tmp <- gsub(open, replacement="", x=tmp, fixed=TRUE)
tmp <- gsub(close, replacement="", x=tmp, fixed=TRUE)
tmp <- gsub("-[1234567890]+-", replacement=",", x=tmp, fixed=FALSE)

## Make a state sequence object from the lists of events
tmp <- gsub(",", replacement="-", x=tmp, fixed=FALSE)
seq.tmp <- seqdef(tmp, sep=",")

## We get the longitudinal event distributions with
head(seqistatd(seq.tmp))

## and the entropy of those distributions as
head(seqient(seq.tmp))

Alternatively you could be interested in the variance of time between the successive events. You would have to extract the time information from the time stamped event sequences not forgetting the null time between simultaneous events.
The complexity index and the turbulence as computed by TraMineR combine information on the sequencing and on duration or spell lengths, and are, therefore, specifically designed for state sequences. The number of transitions and of events in each sequence as suggested by Matthias are relevant longitudinal characteristics of event sequences.

A: I think that such measure would make sense, depending on what do want to measure exactly. Perhaps, you could be a little more precise about the context of your study.
Anyway, if you want to measure the turbulence, you can count the number of transitions and/or the number of events in the sequences (part of the complexity index is computed from the number of transition, for instance). However, such approach would not consider the timing.
Here is an example. First build some event sequences:
library(TraMineR)
data(actcal.tse)
seqe <- seqecreate(actcal.tse)

Now compute the number of event per sequence and the number of transitions. This relies on the character representation of event sequence (for this reason, your event should not contain the "-" or the "," character).
ntrans <- sapply(strsplit(as.character(seqe),
    "-"), length)
nevent <- ntrans - 1 + sapply(strsplit(as.character(seqe),
    ","), length)
## Represent on a scatter plot
smoothScatter(ntrans, nevent)

Regarding transforming the data to TSE. I think that the question is: is the state sequence obtained with TSE_to_STS  suitable to study what you want to study? If yes, then it makes sense.
Hope this helps.

I first came across the brand shortly after Rio was born, when we were literally showered with personalised bathrobes and bath towels (7 in total!). Fortunately, you can't really have too many towels for a baby, so having that many has actually been super handy – and not to mention, a great gift idea! We have a few different variations, with Baby Rio, Rio and Rio Ezra – and he just loves wearing them after bath time.
Personalised toys are also great – especially for when they get a bit older. As Sam is really musical and great on the drums – I couldn't resist getting this Grey Wooden Play Drum for Rio! He's obviously a bit too young for it now, but I've got a feeling it's going to be a (noisy!) favourite of his when he gets that bit older. I also added the Grey Wooden Play Xylophone to the musical mix, which – at the rate he's developing – I'm sure he'll start tinkering with in only a few months.
You can also personalise soft toys (Rio loves his ultra cuddly Grey Bunny), as well as cosy blankets, clothes and trainers on the site. A few months ago, I picked up these super cute Grey Velcro Trainers, which are so neutral and easy to pop on and off. Over the Christmas period, I got him some great festive sleepsuits and vests – and now with Spring (hopefully) just around the corner, I've got some new nautical themed sleepsuits.
I really love this classic Crab Motif Sleepsuit, which is definitely coming with us on holiday to Dubai in a few days. I love the super soft cotton which is really breathable, the easy popper fastenings, and the fact that it's open at the feet (ideal for warm nights). I also got this Sail Boat Motif Sleepsuit – which again is in the softest brushed cotton, and I adore the neutral and classic colour combination.
Last but not least – my all-time favourite: the ultimate Toy Chest. It's definitely more of an investment, but in my opinion, it's probably the nicest toy chest I have come across. Firstly, it's a real classic and timeless piece of furniture – which will look good in any type of home (even if it has to be on show in your kitchen or lounge). Made from white wood, it's a real neutral style, and I've been really impressed by the overall quality. With a 'soft close' mechanism to keep those little fingers safe – it also has ample storage and space to keep all that colourful clutter away!

\section{Introduction}

In this paper we  use a generalized Schr\"odinger  (GS) picture to describe  a  particle in a de Sitter spacetime.  The GS picture is based on the principal series of the infinite-dimensional unitary irreducible representations (UIR) of the Lorentz group \cite{Joos} and a spacetime transformation. The principal series  correspond to the eigenvalues $1+\alpha^2-{\lambda}^2,\,(0\leq\alpha<\infty,\quad\lambda=-s,...,s,{\quad}s = spin)$) of the first ${C_1}={\bf N}^2-{\bf J}^2$, (${\bf N},\,{\bf J}$ are boost and rotation generators) and the eigenvalues $\alpha\lambda$ of the second Casimir operator ${C_2}={\bf N}\cdot{\bf J}$ of the Lorentz group. The representations $(\alpha,\lambda)$ and $(-\alpha,-\lambda)$ are unitarily equivalent. In the momentum representation (${\bf p}$ = momentum, $p_0=\sqrt{m^2c^4+c^2{\bf p}^2}$, $ m=mass$, $s=0$, ${\bf n}^{2}({\theta},{\varphi})=1$),  the  operator ${C_1}({\bf p})$ has the eigenfunctions
\begin{equation}
\label{1.1}
\xi({\bf p},{\alpha},{\bf n}):=[(p_{0}-c{\bf p}\cdot{\bf n})/mc^2]^{-1+i\alpha},\end{equation}

 In \cite{Shap}, it was proposed to classify the states of a relativistic particle by means of  the operators ${C_1}$ and ${C_2}$,  and to carry out an expansion  known as Shapiro transformations or the expansion of the Lorentz group
\begin{equation}
\label{1.2}
\psi({\alpha},{\bf n})=\frac{1}{(2\pi)^{3/2}}
\int\frac{d{\bf p}}{p_0}\,\psi({\bf p})\,\xi^{\ast}({\bf p},{\alpha},{\bf n}).
\end{equation}
Here $\psi({\bf p})$ denotes the wave function of a spinless  particle in the momentum space representation and $\psi({\alpha},{\bf n})$ the wave function of the particle in the ${\alpha}{\bf n}$ representation. The expansion (\ref{1.2})  does not include any dependence on the time  and the space coordinates $t$,  ${\bf x}$, i.e. it is ``spacetime independent''.  In \cite{Kad} the expansion over the functions $\xi^{\ast}({\bf p},{\alpha},{\bf n})$ was used to introduce the ``relativistic configurational'' representation (in following $\rho{\bf n}$-representation, $\rho=\alpha\hbar/mc$) in the framework of a two-paricle equation of the quasipotential type. In this approach the variable $\rho$ was interpeted as the relativistic generalization of a relative coordinate. In \cite{Kad} it was shown that the corresponding operators of the Hamiltonian $H(\rho,{\bf n})$ and the 3-momentum ${\bf P}(\rho,{\bf n})$, defined on the functions $\xi^{\ast}({\bf p},{\rho},{\bf n})$, has a form of the differential-difference operators (their explicit form shall be used in what follows, see Eqs.(\ref{1.32}) and (\ref{1.33})). Various applications of the unitary representations of the Lorentz group and the $\rho{\bf n}$-representation can be found in the literature.

In our previous papers \cite{Fri1} it has been shown that the UIR of the Lorentz group and the expansion (\ref{1.2}) may be also used in a so-called generalized Schr\"odinger picture in which the analogs of the Schr\"odinger operators of a particle are independent of both the time and the space coordinates. It was found that the operators $H(\rho,{\bf n})$,  ${\bf P}(\rho,{\bf n})$,  ${\bf J}({\bf n})$ and ${\bf N}(\rho,{\bf n})={\rho}{\bf n}+({\bf n}\times{\bf J}-{\bf J}\times{\bf n})/2mc$ satisfy the commutations relations of the Poincar\'e algebra in the $\rho{\bf n}$-representation. In the GS picture we have two spacetime independent representations of the Poincar\'e algebra; the ${\bf p}$ and the $\rho{\bf n}$-representation.  This leads to  another Fourier transformation to that in the  standard quantum theory. For a free particle in the Minkowski spacetime  the coordinates $t$, ${\bf x}$ may be introduced in the states  with the help of the transformation
\begin{equation}
\label{1.3}
 S(t,{\bf x})=\exp[-i(tH-{\bf x}\cdot{\bf P})/\hbar],
\end{equation}
where $H$ and ${\bf P}$ are the Hamilton and momentum operators of the particle in the $\rho{\bf n}$ or in the ${\bf p}$-representation. Instead of (\ref{1.2}) we obtain
\begin{equation}
\label{1.4}
S(t,{\bf x})\psi({\rho},{\bf n})=\psi({\rho},{\bf n},t,{\bf x})=\frac{1}{(2\pi)^{3/2}}
\int\frac{d{\bf p}}{p_0}\,\psi({\bf p},t,{\bf x})\,\xi^{\ast(0)}({\bf p},{\rho},{\bf n}),
\end{equation}
where $\psi({\bf p},t,{\bf x})=\psi({\bf p})\exp[-ix{\cdot}p/\hbar]$. It follows that in the GS picture the  spacetime coordinates appear in the states in  the $\rho{\bf n}$ and in the ${\bf p}$-representation. The use of the $\rho{\bf n}$-representation in this picture  makes it possible to describe extendent objects like strings.

For the functions $\psi({\rho},{\bf n},t,{\bf x})$ and $\psi({\bf p},t,{\bf x})$ we have
\begin{equation}
\label{1.5}
i\hbar\frac{\partial}{\partial{t}}\psi=H\psi,\quad{-i}\hbar\frac{\partial}{\partial{\bf x}}\psi={\bf P}\psi.
\end{equation}
In this  equations the operators $H$ and ${\bf P}$ induce on the left-hand-side the operators of the Lie-algebra of Killing vectors of the  Minkowski spacetime. A full Poincar\'e algebra contain in addition to the operators in (\ref{1.5}) the Lorentz rotation and boost generators.  For the first Casimir operator of the Poincar\'e group  we have
\begin{equation}
\label{1.6}
{C}(t,{\bf x})\psi({\bf p},t,{\bf x})={C}({\bf p})\psi({\bf p},t,{\bf x}),{\quad}{C}(t,{\bf x})\psi({\rho},{\bf n},t,{\bf x})={C}(\rho{\bf n})\psi({\rho},{\bf n},t,{\bf x}).
\end{equation}
In the paper \cite{Fri2}, it was shown that equations like (\ref{1.5})  may be used to describe a particle in an Anti-de Sitter spacetime. It was found that operators with an external field in the ${\rho}{\bf n}$-representation  which corresponds to an attractive force induce operators ${K}_a(t,x^{i})$ which are related to Killing vectors  of the AdS spacetime $(a=1,2,...10;$ $\lbrace{x^{i}\rbrace}$, $i=1,2,3.)$
\begin{equation}
\label{1.7}
{K}_a(t,x^{i})\widetilde{\Phi}({\rho},{\bf n},t,x^{i})=B _a({\rho},{\bf n})\widetilde{\Phi}({\rho},{\bf n},t,x^{i}).
\end{equation}
Here $\widetilde{\Phi}$ denotes the wave function of the particle in  the $\rho{\bf n}$-representation. The operators  ${K}_a(t,x^{i})$ satisfy  the same commutation rules as  the spacetime independent operators $B _a({\rho},{\bf n})$ , except for the minus signs on the right-hand sides. In the framework of GS-picture, a particle in a spacetime is free if a set of operators in the $\rho{\bf n}$ or in the ${\bf p}$-representation force the introduction of  Killing vector fields of this spacetime.

In the present paper we will show that  an external massless field in the  $\rho{\bf n}$ or in the momentum representation which corresponds to a repulsive force induce  operators which are related to Killing vectors of the de Sitter spacetime. We want to show that a particle in a de Sitter  spacetime may be described by the equations like (\ref{1.7}). The external fields in the ${\bf p}$ or in the  $\rho{\bf n}$-representation do violate the commutation relations of the Poincar\'e algebra. We have the problem of determining  observables in the GS picture. Here we  use only the coordinate system which corresponds to an exponentially expanding world \cite{Bir,Stro,Obu}. We shall show that in this coordinates  the spacetime independent momentum operators of the particle in addittion to the external field contain the Lorentz boost generators.  In Sect.2 we study the  motion of a particle in a two dimensional de Sitter spacetime. We use the ${\rho}$-representation. In Sect.3 the four dimensional de Sitter spacetime and the $\rho{\bf n}$-representation  are used. In Appendix we use the momentum representation.
\section{Motion in a two dimensional dS spacetime}

In a  two dimensional Minkowski spacetime the motion  of a free particle is described by the equations
\begin{equation}
\label{1.8}
i\hbar\frac{\partial}{\partial{t}}\psi(\rho,t,x)=H(\rho)\psi(\rho,t,x),\quad{-i}\hbar\frac{\partial}{\partial{x}}\psi(\rho,t,x)=P(\rho)\psi(\rho,t,x),
\end{equation}
where the Hamilton operator $H(\rho)$ and the momentum operator $P(\rho)$ have the form
\begin{equation}
\label{1.9}
H({\rho})=mc^2\cosh(-\frac{i\hbar}{mc}{\partial}_{{\rho}}),{\quad}P({\rho})=mc\sinh(-\frac{i\hbar}{mc}{\partial}_{{\rho}}).
\end{equation}
 The operators $H(\rho)$, $P(\rho)$  and the operator $N(\rho)$  ($N(\rho)=\rho)$ satisfy the commutation relations of the Poincar\'e algebra,
\begin{equation}
\label{1.10}
\lbrack{N},P\rbrack=i\frac{\hbar}{mc^2}H,\quad\lbrack{P},{H}\rbrack=0,\quad\lbrack{H},{N}\rbrack=-i\frac{\hbar}{m}P.
\end{equation}
In (\ref{1.6}), in a model of a relativistic oscillator we have used an external field which corresponds to an attractive force $(\omega$ = frequency)
\begin{equation}
\label{1.11}
\widetilde{H}^{'}(\rho)=\frac{m{\omega}^2}{2}\rho\left(\rho-i\frac{\hbar}{mc}\right)e^{-i\frac{\hbar}{mc}{\partial}_{\rho}},{\quad}\widetilde{P}_1^{'}(\rho)=\frac{m{\omega}^2}{2c}\rho\left(\rho-i\frac{\hbar}{mc}\right)e^{-i\frac{\hbar}{mc}{\partial}_{\rho}}.
\end{equation}
 The operators
\begin{equation}
\label{1.12}
\hat{P_0}(\rho)=H({\rho})+\widetilde{H}^{'}(\rho),{\quad}\hat{P_1}(\rho)=P({\rho})+\widetilde{P}_1^{'}(\rho),
\end{equation}
and $\rho$ satisfy the commutation relations
\begin{equation}
\label{1.13}
\lbrack\rho,\hat{P_1}\rbrack=i\frac{\hbar}{mc^2}\hat{P_0},\quad\lbrack\hat{P_1},\hat{P_0}\rbrack=-i\hbar{m}{\omega}^2\rho,\quad\lbrack\hat{P_0},\rho\rbrack=-i\frac{\hbar}{m}\hat{P_1}.
\end{equation}

In the nonrelativistic limit the operators $\hat{P_0}(\rho)-mc^2$ and $\hat{P_1}(\rho)$ assume the form
\begin{equation}
\label{1.14}
\hat{P_0}_{\rm{nr}}=-\frac{{\hbar}^2}{2m}\frac{{\partial}^2}{\partial{\rho}^2}+\frac{m{\omega}^2}{2}{\rho}^2,{\quad}\hat{P_1}_{\rm{nr}}=-i\hbar\frac{\partial}{\partial\rho}.
\end{equation}
It was found that the operators  $\hat{P_0}$,  $\hat{P_1}(\rho)$ and $\rho$ induce  operators which are related to  the Killing vectors of an AdS spacetime.

Here, in analogy to (\ref{1.11}) for the external field which corresponds to a repulsive force  we use the following operators
\begin{equation}
\label{1.15}
H^{'}_0(\rho)=-\frac{mc^2}{2{\ell}^2}\rho\left(\rho-i\frac{\hbar}{mc}\right)e^{-i\frac{\hbar}{mc}{\partial}_{\rho}},{\quad}P^{'}_1(\rho)=-\frac{mc}{2{\ell}^2}\rho\left(\rho-i\frac{\hbar}{mc}\right)e^{-i\frac{\hbar}{mc}{\partial}_{\rho}}
\end{equation}
where the constant $\ell$  has the dimension of length. Here the quantity $\ell$ is related to the radius of a two dimensional de Sitter spacetime.

The operators
\begin{equation}
\label{1.16}
{\Pi_0}(\rho)=H(\rho)+H^{'}_0(\rho),\quad{\Pi_1}(\rho)=P(\rho)+P^{'}_1(\rho),
\end{equation}
satisfy the commutation relations
\begin{equation}
\label{1.17}
{\lbrack}{\rho},{\Pi_1}\rbrack=i\frac{\hbar}{mc^2}{\Pi_0},\quad\lbrack{\Pi_1},{\Pi_0}\rbrack=i\hbar{m}{\frac{c^2}{\ell^2}}{\rho},\quad\lbrack{\Pi_0},{\rho}\rbrack=-i\frac{\hbar}{m}{\Pi_1}.
\end{equation}
The Casimir operator is a multiple of the identity operator ${I}$
\begin{equation}
\label{1.18}
C(\rho)=-\frac{{\ell}^2}{(\hbar{c})^2}{\lbrace}{\Pi_0}^{2}-c^2{\Pi}_1^{2}{\rbrace}-\frac{m^2c^2}{{\hbar}^2}{\rho}^2=-\left(\frac{{m^2c^2\ell}^2}{{\hbar}^2}\right){I}.
\end{equation}

 Now in accordance with (\ref{1.7}),  we  introduce three operators ${\cal}K_{10}$, $K_{12}$ and  $K_{02}$  in terms of the spacetime coordinates of a two dimensional de Sitter spacetime with  the  same commutation rules  as  the operators ${\Pi_0}$, ${\Pi_1}$ and $\rho$,  except for the minus signs on the right-hand sides  ($d=2$)
\begin{equation}
\label{1.19}
\lbrack{K_{10},K_{1d}}\rbrack=-\frac{\imath\hbar}{mc^2}K_{0d},{\quad}\lbrack{K_{1d},K_{0d}}\rbrack=-\imath\hbar{m}\frac{c^2}{{\ell}^2}{K_{10}},{\quad}\lbrack{K_{0d},K_{10}}\rbrack=\frac{\imath\hbar}{m}{K_{1d}}.
\end{equation}
For the operators $K_{0d}$, $K_{1d}$ and $K_{10}$ we choose the  following realisation
\begin{equation}
\label{1.20}
K_{0d}(t,x)=i{\hbar}(\frac{\partial}{\partial{t}}-\frac{cx}{{\ell}}\frac{\partial}{\partial{x}}),
\end{equation}
\begin{equation}
\label{1.21}
K_{1d}(t,x)=i\frac{\hbar}{\ell}[x\frac{\partial}{\partial{ct}}-(\frac{{x^2}}{2\ell}+\frac{\ell}{2}e^{-2ct/\ell})\frac{\partial}{\partial{x}}-\frac{\ell}{2}\frac{\partial}{\partial{x}}],
\end{equation}
\begin{equation}
\label{1.22}
K_{01}(t,x)=i\frac{\hbar}{mc}[-x\frac{\partial}{\partial{ct}}+(\frac{{x^2}}{2\ell}+\frac{\ell}{2}e^{-2ct/\ell})\frac{\partial}{\partial{x}}-\frac{\ell}{2}\frac{\partial}{\partial{x}}].
\end{equation}
These operators are related to Killing vectors of the de Sitter spacetime with metric
\begin{equation}
\label{1.23}
ds^2=c^2dt^2-e^{2ct/{\ell}}dx^2.
\end{equation}
Using the relations (\ref{1.17}) and (\ref{1.19}) we find that a free particle in dS spacetime (\ref{1.23}) is describe by the quantum equations
\begin{equation}
\label{1.24}
K_{0d}(t,x)\Phi(\rho,t,x)={\Pi_0}\Phi(\rho,t,x),{\quad}K_{1d}(t,x)\Phi(\rho,t,x)={\Pi_1}\Phi(\rho,t,x),
\end{equation}
\begin{equation}
\label{1.25}
K_{10}(t,x)\Phi(\rho,t,x)= \rho\Phi(\rho,t,x).
\end{equation}
Here $\Phi(\rho,t,x)$ denotes the wave function of the particle.

For the  Casimir operators $C(\rho)$ and
\begin{equation}
\label{1.26}
C(t,x)=\frac{l^2}{c^2}\frac{{\partial}^2}{\partial{t}^2}+\frac{l}{c}\frac{{\partial}}{\partial{t}}-l^2e^{-2ct/l}\frac{{\partial}^2}{\partial {x}^2}
\end{equation}
we have
\begin{equation}
\label{1.27}
C(t,x){\Phi}(\rho;t,x)=C(\rho){\Phi}(\rho;t,x).
\end{equation}

To proceed further, we must construct a quantum  equation of the particle  with the property given in (\ref{1.5}a) or in (\ref{1.5}b) above. The explicit forms of the operators $K_{0d}(t,x)$, $K_{1d}(t,x)$  show that  the operators ${\Pi_0}(\rho)$ and  ${\Pi_1}(\rho)$ in (\ref{1.24}) cannot be defined as the Hamilton and the momentum operators of the particle. In the metric (\ref{1.23})  we can construct  a  momentum operator by using  two sums  $K_{1d}+\frac{mc}{\ell}K_{01}$, and $\hat\Pi_{1}(\rho)+\frac{mc}{\ell}\rho$.  We obtain the equation
\begin{equation}
\label{1.28}
-i\hbar\frac{\partial}{\partial{x}}\Phi(\rho;t,x)=[\Pi_{1}(\rho)+\frac{mc}{\ell}{\rho}]\Phi(\rho;t,x),
\end{equation}
which defines  the operator on the right-hand side as the momentum operator of the particle in the $\rho$-representation.
 This operator in addition to the external field contains the operator $\rho$ multipled by the mass $m$ and the parameter $\frac{c}{\ell}$.
 For the eigenfunctions $v_{\kappa}(\rho)$ of the  operator $\Pi_{1}(\rho)+\frac{mc}{\ell}\rho$ we have
\begin{equation}
\label{1.29}
(\Pi_{1}(\rho)+\frac{mc}{\ell}\rho)v_{\kappa}(\rho)={\kappa}v_{\kappa}(\rho),
\end{equation}
where ${\kappa}$ denotes the value of the  momentum of the particle in the de Sitter spacetime. A general solution of $\Phi(\rho;t,x)$  can be written in the form
\begin{equation}
\label{1.30}
\Phi(\rho;t,x)={\int}v_{\kappa}(\rho)f_{\kappa}(t,x)d{\kappa},
\end{equation}
where $f_{\kappa}(t,x)$ are the eigenfunctions of the operators  $C(t,x)$.

For the propagator of the particle we have the expression
\begin{equation}
\label{1.31}
{\cal K}(2,1)=\int{v_{\kappa}({\rho}_2)}f_{\kappa}(t_2,x_2)v^{*}_{\kappa}({\rho}_1)f^{*}_{\kappa}(t_1,x_1)d\kappa.
\end{equation}
\section{Motion in a four dimensional dS spacetime}

The operators $H(\rho,{\bf n})$ and  ${\bf P}(\rho,{\bf n})$ in (\ref{1.5})   have the form $(spin=0)$
\begin{equation}
\label{1.32}
H(\rho,{\bf n})=mc^2\cosh\left(\frac{i\hbar}{mc}{\partial}_{\rho}\right)+\frac{i\hbar{c}}{{\rho}}{\sinh}\left(\frac{i\hbar}{mc}{\partial}_{\rho}\right) +\frac{{\bf L}^2({\bf n})}{2m{\rho}^2}e^{\frac{i\hbar}{mc}{\partial}_{\rho}},
\end{equation}
\begin{equation}
\label{1.33}
{\bf P}={\bf n}H/c-\frac{mc}{\rho}e^{{\frac{i\hbar}{mc}{\partial}_{\rho}}}{\bf N}(\rho,{\bf n}).
\end{equation}
Here ${\bf L}({\bf n})$ and ${\bf N}(\rho,{\bf n})={\rho}{\bf n}+({\bf n}\times{\bf L}-{\bf L}\times{\bf n})/2mc$ are the operators of the Lorentz algebra in the $\rho{\bf n}$-representaion. For a particle in an external field which corresponds to a repulsive force  we use the operators
\begin{equation}
\label{1.34}
{\Pi_0}(\rho,{\bf n})=H(\rho,{\bf n})+H'_0(\rho,{\bf n}),
\end{equation}
\begin{equation}
\label{1.35}
{\Pi_i}(\rho,{\bf n})=P_i(\rho,{\bf n})+P'_i(\rho,{\bf n}),
\end{equation}
where
\begin{equation}
\label{1.36}
H'_0=-\frac{mc^2}{2{\ell}^2}\left(\rho-i\frac{\hbar}{mc}\right)^2e^{-i\frac{\hbar}{mc}{\partial}_{\rho}},{\quad}P'_i= -n_i\frac{mc}{2{\ell}^2}\left(\rho-i\frac{\hbar}{mc}\right)^2e^{-i\frac{\hbar}{mc}{\partial}_{\rho}}.
\end{equation}
Here the quantity $\ell$ is related to the radius of a four dimensional de Sitter spacetime.

We have
\begin{equation}
\label{1.37}
{H'}^2_0-c^2{{\bf P}'}^2=0.
\end{equation}
Thus we see that the external field corresponds to  a massless field.
The operators $H'_0$,  ${\bf P}'$,  ${\bf L}({\bf n})$ and ${\bf N}(\rho,{\bf n})$ satisfy the commutations relations of the Poincar\'e algebra.

For the operators ${\Pi_0}(\rho,{\bf n})$, ${\Pi_i}(\rho,{\bf n})$ and ${\bf L}({\bf n})$, ${\bf N}(\rho,{\bf n})$ we have
\begin{equation}
\label{1.38}
\lbrack{N_i},{\Pi_j}\rbrack=\frac{\imath\hbar}{mc^2}\delta_{ij}{\Pi_0},\quad\lbrack{\Pi_i},{\Pi_0}\rbrack=\imath\hbar{m}{\frac{c^2}{{\ell}^2}}{N_i}\quad\lbrack{\Pi_0},{N_i}\rbrack=-\frac{\imath\hbar}{m}{\Pi_i},
\end{equation}
\begin{equation}
\label{1.39}
\lbrack{\Pi_i},{\Pi_j}\rbrack=\imath\frac{\hbar}{{\ell}^2}\epsilon_{ijk}{L_k},\quad\lbrack{L_i},{\Pi_0}\rbrack=0,\quad\lbrack{\Pi_i},L_j\rbrack=\imath\hbar\epsilon_{ijk}{\Pi_k},
\end{equation}
\begin{equation}
\label{1.40}
\lbrack{L_i},{L_j}\rbrack=\imath\hbar\epsilon_{ijk}{L_k},\quad
\lbrack{N_i},{N_j}\rbrack=-\frac{\imath\hbar}{m^2c^2}\epsilon_{ijk}{L_k},\quad\lbrack{N_i},{L_j}\rbrack=\imath\hbar\epsilon_{ijk}{N_k}.
\end{equation}

The operators $\lbrace{\Pi_0},{\Pi}_i,{N_i},{L_i}\rbrace$  form a  basis for the $\rho{\bf n}$-representation of the $SO(1,4)$ group generators and correspond to constants of motion.
The Casimir operator
\begin{equation}
\label{1.41}
C(\rho,{\bf n})=-\frac{{\ell}^2}{(\hbar{c})^2}\left\lbrace{\Pi_0}^{2}-c^2\sum_{i=1}^{3}{\Pi}_i^{2}\right\rbrace-\frac{m^2c^2}{{\hbar}^2}{\bf N}^2+\frac{1}{{\hbar}^2}{\bf L}^2
\end{equation}
is a multiple of the identity operator
\begin{equation}
\label{1.42}
C(\rho,{\bf n})=(-\frac{m^2{c^2}{\ell}^2}{{\hbar}^2}-2){I}.
\end{equation}

In the four dimensional dS spacetime we use the metric which corresponds to an exponentially expanding world
\begin{equation}
\label{1.43}
ds^2=c^2dt^2-e^{2ct/{\ell}}dx_{i}dx^{i}.
\end{equation}
Here the quantity $\ell$ is related to the radius of  the four dimensional de Sitter spacetime.

Now we introduce ten operators  which related to the Killing vectors of the spacetime (\ref{1.43}) , $(r^2=({x^i})^2)$
\begin{equation}
\label{1.44}
K_{04}=i{\hbar}(\frac{\partial}{\partial{t}}-\frac{c{x^i}}{{\ell}}\frac{\partial}{\partial{{x^i}}}),
\end{equation}
\begin{equation}
\label{1.45}
K_{i4}=i\frac{\hbar}{\ell}[x_i(\frac{\partial}{\partial{ct}}-\frac{{x^i}}{\ell}\frac{\partial}{\partial{{x^i}}})-\frac{\ell}{2}\frac{\partial}{\partial{x_i}}-(\frac{\ell}{2}e^{-2ct/\ell}-\frac{{r}^2}{2\ell})\frac{\partial}{\partial{x_i}}],
\end{equation}
\begin{equation}
\label{1.46}
K_{0i}=i\frac{\hbar}{mc}[-x_i(\frac{\partial}{\partial{ct}}-\frac{{x^i}}{\ell}\frac{\partial}{\partial{{x^i}}})-\frac{\ell}{2}\frac{\partial}{\partial{x_i}}+(\frac{\ell}{2}e^{-2ct/\ell}-\frac{{r}^2}{2\ell})\frac{\partial}{\partial{x_i}}],
\end{equation}
\begin{equation}
\label{1.47}
K_{ij}=i{\hbar}(x_i\frac{\partial}{\partial{x^j}}-x_j\frac{\partial}{\partial{x^i}}).
\end{equation}
This operators satisfy the same commutation rules as  the spacetime independent  operators ${\Pi_0}(\rho,{\bf n})$, ${\Pi_i}(\rho,{\bf n})$ and ${\bf L}({\bf n})$, ${\bf N}(\rho,{\bf n})$, except for the minus signs on the right-hand sides $(d=4)$
\begin{equation}
\label{1.48}
\lbrack{K_{i0},K_{jd}}\rbrack=-\frac{\imath\hbar}{mc^2}\delta_{ij}K_{0d},\quad\lbrack{K_{id},K_{0d}}\rbrack=-\imath\hbar{m}\frac{c^2}{{\ell}^2}{K_{i0}},
\end{equation}
\begin{equation}
\label{1.49}
\lbrack{K_{0d},K_{i0}}\rbrack=\frac{\imath\hbar}{m}{K_{i4}}\quad\lbrack{K}_{id},{K}_{jd}\rbrack=-\imath\frac{\hbar}{{\ell}^2}K_{ij},\quad\lbrack{K_{ij},K_{0d}}\rbrack=0,
\end{equation}
\begin{equation}
\label{1.50}
\lbrack{K}_{id},K_{ik}\rbrack=\imath\hbar{K}_{kd},\quad\lbrack{K_{i0},K_{j0}}\rbrack=\frac{\imath\hbar}{m^2c^2}K_{ij},\quad\lbrack{K_{i0},K_{ik}}\rbrack=\imath\hbar{K_{k0}}.
\end{equation}
Just as we did in (\ref{1.24}) and (\ref{1.25}), we  write ($\Phi=\Phi(\rho,{\bf n},t,x^i)$)
\begin{equation}
\label{1.51}
K_{0d}(t,x^i)\Phi=\Pi_0(\rho,{\bf n})\Phi,{\quad}K_{id}(t,x^i)\Phi={\Pi_i}(\rho,{\bf n})\Phi,
\end{equation}
\begin{equation}
\label{1.52}
K_{i0}(t,x^i)\Phi= N_i(\rho,{\bf n})\Phi,{\quad}K_{ij}(x^i)\Phi= {\varepsilon}_{ijk}L_k({\bf n})\Phi.
\end{equation}
These quantum equations may be used to describe a free particle in de Sitter spacetime (\ref{1.43}).

For the Casimir operators we obtain
\begin{equation}
\label{1.53}
C(t,{x^i})\Phi=C((\rho,{\bf n})\Phi=(-\frac{m^2{c^2}{\ell}^2}{{\hbar}^2}-2)\Phi
\end{equation}
where
\begin{equation}
\label{1.54}
C(t,{x^i})=\frac{{\ell}^2}{c^2}\frac{{\partial}^2}{\partial {t}^2}+3\frac{\ell}{c}\frac{\partial}{\partial{t}}-{\ell}^2e^{-2{\nu}t}{\nabla}^{2}.
\end{equation}

Now we have a situation fully analogous to that described in the previous section. From the equation
\begin{equation}
\label{1.55}
i{\hbar}(\frac{\partial}{\partial{t}}-\frac{c{x^i}}{{\ell}}\frac{\partial}{\partial{{x^i}}})\Phi(\rho,{\bf n},t,{x^i})={\Pi_0}(\rho,{\bf n})\Phi(\rho,{\bf n},t,{x^i})
\end{equation}
follows that the operator ${\Pi_0}(\rho,{\bf n})$ cannot be defined as the Hamilton operator of the particle.
In this metric we can again construct the momentum operators by using   two sums \begin{equation}
\label{1.56}
K_{i4}+\frac{mc}{\ell}K_{0i}=\Pi_{i}+\frac{mc}{\ell}N_i.
\end{equation}
We obtain
\begin{equation}
\label{1.57}
-i\hbar\frac{\partial}{\partial{x_i}}\Phi(\rho,{\bf n},t,{x^i})=[\Pi_{i}(\rho,{\bf n})+\frac{mc}{\ell}N_i(\rho,{\bf n})]\Phi(\rho,{\bf n},t,{x^i}).
\end{equation}
Eqs. (\ref{1.57})  defines the operators of the right-hand sides  as the momentum operators of the particle in the $\rho{\bf n}$-representation. These operators in addition to the external field contain the Lorentz boost generators $N_i(\rho,{\bf n})$ multipled by the mass $m$ and the Hubble parameter $\frac{c}{\ell}$.

 A general solution of $\Phi$ can be written in the form (${\vec\kappa}$=momentum)
\begin{equation}
\label{1.58}
\Phi(\rho,{\bf n},t,{x^i})={\int}v_{\vec\kappa}(\rho,{\bf n})f_{\vec\kappa}(t,{x^i})d{\kappa}_{1}d{\kappa}_{2}d{\kappa}_{3}
\end{equation}
where $v_{\vec\kappa}(\rho,{\bf n})$ satisfy the equation
\begin{equation}
\label{1.59}
\sum_{i=1}^{3}(\Pi_{i}+\frac{mc}{\ell}N_i)^2v_{\vec\kappa}(\rho,{\bf n})={\vec\kappa}^2v_{\vec\kappa}(\rho,{\bf n}),
\end{equation}
and $f_{\vec{\kappa}}(t,{x^i})$ are the eigenfunctions of the Casimir operator  $C(t,{x^i})$.
\section{Conclusion}
In this paper we have shown that  a generalized Schr\"odinger (GS) picture may be used to describe a free particle in a de Sitter spacetime.  In this picture the analogs of the Schr\"odinger operators of a particle are independent of both the time and space coordinates. These operators force the introduction of operators of the Killing vectors of a spacetime. The presence of this vector fields  in a quantum equation determines  the motion of a free particle in the correspondig spacetime. It was found that the spacetime independent operators with an external massless field  which corresponds to a $\it{repulsive}$ $\it{force}$ induce the operators  of Killing vectors of  the de Sitter spacetime.  The problem of determining the observables  is based  on  choosing of  the coordinate system in this  spacetime. We have shown that in the coordinates which correspond to an exponentially expanding world the spacetime independent momentum operators of the particle  in addition to the external field contain the Lorentz boost generators miltipled by the mass of the particle and the Hubble parameter. We hope that the formalism that has been presented here will be employed for solving problems in relativistic quantum physics, astrophysics and cosmology.
\section{Appendix}
In a two dimensional Minkowski spacetime  a free relativistic particle is described by the equations (\ref{1.5}). In the  momentum representation  the Hamilton   and the momentum operator may be written in  the form ($\chi=-\ln[(p_0-cp)/mc^2]$)
\begin{equation}
\label{1.60}
p_0={mc^2}{\cosh}{\chi},{\quad}p=mc\sinh\chi.
\end{equation}
For a particle in an external field which corresponds to a repulsive force we use the operators
 \begin{equation}
\label{1.61}
\Pi_0(\chi)=mc^2\left[\cosh\chi+\frac{1}{2}\left(\frac{\hbar}{mc{\ell}}\right)^2{e}^{\chi}\left\lbrace\frac{d^2}{d{\chi}^2}+\frac{d}{d\chi}\right\rbrace\right],
\end{equation}
\begin{equation}
\label{1.62}
\Pi_1(\chi)=mc\left[\sinh\chi+\frac{1}{2}\left(\frac{\hbar}{mc{\ell}}\right)^2{e}^{\chi}\left\lbrace\frac{d^2}{d{\chi}^2}+\frac{d}{d\chi}\right\rbrace\right],
\end{equation}
and  $N(\chi)=i\frac{\hbar}{mc}\frac{\partial}{\partial{\chi}}$.
They  satisfy the commutation relations
\begin{equation}
\label{1.63}
[N(\chi),\Pi_1(\chi)]=i\frac{\hbar}{mc^2}{\Pi_0}(\chi),\quad[{\Pi}_1(\chi),{\Pi_0}(\chi)]=i\hbar\frac{mc^2}{l^2}{N(\chi)},
\end{equation}
\begin{equation}
\label{1.64}
[\Pi_0(\chi),N(\chi)]=-i\frac{\hbar}{m}{\Pi}_1(\chi).
\end{equation}
We have
\begin{equation}
\label{1.65}
{K}_{d0}(t,x){\Phi}(\chi;t,x)={\Pi}_{0}(\chi){\Phi}(\chi;t,x),
\end{equation}
\begin{equation}
\label{1.66}
{K}_{1d}(t,x){\Phi}(\chi;t,x)={\Pi}_1(\chi){\Phi}(\chi;t,x),{\quad}K_{01}(t,x){\Phi}(\chi;t,x)=N(\chi){\Phi}(\chi;t,x).
\end{equation}
where the function ${\Phi}(\chi;t,x)$ describe a particle in two dimensional de Sitter spacetime with metric (\ref{1.23}).

Now, from  the operators $K_{1d}+\frac{mc}{\ell}K_{01}$, and $\hat\Pi_{1}+\frac{mc}{\ell}N$ we obtain the equation
\begin{equation}
\label{1.67}
-i\hbar\frac{\partial}{\partial{x}}\Phi(\chi;t,x)=(\hat\Pi_{1}(\chi)+\frac{mc}{\ell}N(\chi))\Phi(\chi;t,x)
\end{equation}
which defines  the operator $\hat\Pi_{1}(\chi)+\frac{mc}{\ell}N(\chi)$ as the momentum operator of the particle  in the $\chi$-representation.
 The function $\Phi(\chi;t,x)$  can be written in the form

Groma Modell N
For every kind of writer, there's a typewriter. Groma excels at functional style. While they'll never win a speed contest, the solid, measured feel of the keystroke, along with a bold and distinctive typeface, makes Groma typewriters a great choice for the connoisseur of prose and poetry.
The Modell N is an artist's typewriter, with its sweeping curves and graceful valleys. If objects possess a soul, sitting at this machine and pressing its keys, may change your writing and influence your thinking. While most typewriter manufacturers prized speed, a Groma causes you to slow down and consider your words. It's thoughtful design carries through to thoughtful writing. Deliberate, but not ponderous.
Olympia typewriters with their spring loaded keys are telling you to speed up. Spring into action! Go faster! For writers who are working on big projects, go for it. But if you're the type of writer who likes to post their page of poetry to Instagram, then get a Groma. The typeface is strong and is easily captured with a smartphone camera. Even if you're not into self-promotion, the Modell N is like your personal printing press. Roll in some nice paper or cardstock and make art.

And who but a master artist or architect would design a carriage return lever that perfectly matches the contours of the body? One can't help but note the similarities between the Modell N and a Frank Gehry building. And if you're into feng shui, the strategically placed red keys induce a positive flow of energy. This isn't the type of machine suited for the mass assembly line, nor is it designed for the typist expecting a "standard" office machine. It'll never be that quick and nimble. But that doesn't mean it isn't engineered for perfection. From drawing board to final product, it must've been a glorious day for the Groma designers when the first machine rolled off the factory floor. It's art that works. It's art that constructs art. Sir Jony Ive at Apple could hardly do better. And unlike anything the big tech companies produce, the Groma typewriter will be used and passed down for generations.

Skip Fogarty says:
Ok Daniel. You've done it again! Great post, makes me ache to own my own Groma. It reminds me a bit of my SC no. 3, and the Sterling streamlines. Thanks for your inspiration.
Scott K says:
I'm pretty certain these are the best looking typewriters ever made. The are just tooooo beautiful. They out do everything else from that era.
I have a Model T. Not only is it beautiful, it's reliable. To simply own one for aesthetic purposes would be a shame. The Groma models are often viewed as somewhat prissy, but that's a misconception. You simply have to be disciplined in your movements. Just because the Groma doesn't stand for frantic, desperate typing doesn't mean it's impractical. What it lacks in speed it makes up for in quality. I'd argue that the Groma ultimately saves time, because it forces you to construct with greater precision. Anytime you type on a Groma, you're aware that every word matters. Typing on a Groma Model N or T means less waste.
As Daniel said, it's a machine for the aesthete who wants to create, a lover of beauty who desires function.
Typing on my Olivetti is much easier and faster, but I always use my Groma for raw creation. The Groma demands concentration and soul; the moment you try to half-ass your prose, the Groma rebels. It keeps you in check. It is an unforgiving muse.
Great follow up, Felix! The Unforgiving Muse! Stern, yet loving. Your writing will grow stronger with a Groma.
Hugo Torres says:
I bought in the early days of this year a Modell N, it's my first typewriter and probably my favorite one.
Lucky me to get one with the rune key in a unbelievable selling price.. It was in bad condition, the case was awful and the machine full of old oil and dirty everywhere. After the restoration is with great look and working very well, and full original parts (except the skin on cover and inside that I use on case).
Unfortunately last week the spring of carriage had broke, but I'm searching for some company to do one like the original.

Sunday, May 5 will mark the tenth anniversary of the killing of Kendra James. The 21-year-old Black woman was shot and killed, despite being unarmed, by Officer Scott McCollister during a traffic stop.
The Albina Ministerial Alliance Coalition for Justice and Police Reform will be leading a memorial vigil at the Greater Faith Baptist Church at 931 N. Skidmore. This site is just yards away from where the shooting occurred.
According to a statement from the alliance, "James' death was a touchstone for many in Portland who saw the shooting of an unarmed African American woman as a symptom of a Police Bureau needing major reforms. In many ways her death led the accountability efforts down the path to the changes now being sought as a remedy by the Department of Justice in their lawsuit against the City."
According to reports, the incident occurred when James tried to drive away from the traffic stop. McCollister told investigators that most of his body was inside the car when he tried to remove her. He said he tried to pull her out by her hair, pepper spray her and use a Taser but all attempts were unsuccessful. When she put the car into drive, he fired his gun because he thought his life was in danger, he claimed.
Police Chief Mark Kroeker and former Mayor Vera Katz, then police commissioner, disciplined McCollister for unsatisfactory performance.
McCollister was suspended for 5.5 months before an arbitrator lifted the suspension.
The arbitrator, John C Truesdale, ordered the city to pay McCollister's lost wages and expunge the suspension from his record because the Portland Police Bureau didn't conduct a full internal affairs investigation. Such investigations are required by bureau policy in cases where officers use deadly force.
Kroeker was forced to resign that same year.
On Dec. 17 of 2012, the U.S. Department of Justice filed a complaint against the city, based on an 18-month investigation of the police bureau. The City and justice officials filed a settlement agreement at the same time.
As of Feb. 20, the alliance, justice department, City and the Portland Police Association have been in mediation talks to try and resolve their differences on police reforms.
The justice department concluded Portland police engaged in a 'pattern or practice' of violating the civil rights of people with mental illness, or those thought to have mental illness.
The settlement required changes to police use of force and Taser policies, along with stepped up crisis intervention, training, supervision, accountability and discipline procedures. The settlement will cost $3.5 million to implement, according to City estimates.
Portland Police Association opposes the settlement on the grounds that it undermines the union's collective bargaining rights. The judge granted the association the right to be a legal party with a right to intervene in some of the reforms, based on an earlier Ninth Circuit Court of Appeals court ruling that recognized settlements like these may affect collective bargaining agreements.
The Albina Ministerial Alliance wants more public input, on the grounds that the settlement fails to address concerns about racially biased policing, and does not include adequate oversight to ensure the agreement works.
Sunday's vigil begins at 5 p.m. and members of James' family will be in attendance.

About Act of Valor Part 3 – About the Novelization
Written by George GaldorisiPosted in Blog,Book NewsTags: act of valor, aov book, bandito brothers, george galdorisi, military book, novelization, relativity media, tom clancy presents act of valorMarch 19, 2012No comments
Like many movies, there is a novelization attached to Act of Valor. The book, Tom Clancy Presents: Act of Valor, a Penguin Premium Paperback, by Dick Couch and George Galdorisi was published in January (Penguin printed 400,000 copies, unusually high for a novelization, but anticipating that Act of Valor would "open big when it was released), six weeks before Act of Valor was released. Tom Clancy Presents: Act of Valor has enjoyed several months on both the New York Times and Publisher's Weekly mass market paperback best-seller lists, rising as high as #4 on both lists and moving into its second printing only six weeks after its initial publication date. How the novelization came to pass is a unique story unto itself.
In April of 2011, co-author Dick Couch and I were invited by the principals at the Bandito Brothers film company to visit them at their Culver City studio and see a screening of their new film. After the screening, we were sitting with one of the directors, Mike "Mouse" McCoy, composing ourselves after the event. "Composing ourselves" isn't an overstatement or hyperbole. Act of Valor is an emotional film and a moving one, and we were, at once, completely riveted and blown away by what we had seen.
We talked with Mouse McCoy and Bandito Brothers COO, Max Leitman, about our impressions of the film and talked about some other initiatives related to the film, as well as about some of Bandito Brothers other projects (the day we visited they were in the middle of filming a commercial for the new BMW X6). There was a slight lull in the conversation and I turned to Mouse McCoy and asked, "So, who's writing the book?"
"The book?" he replied. "No one. We've been so busy making the movie we hadn't had time to think about that."
"Well, would you consider having Dick and I do that?" I said. And with that, the novelization of Act of Valor was underway.
About Act of Valor Part 2 – Behind the Scenes
Written by George GaldorisiPosted in Blog,Book NewsTags: act of valor, aov book, bandito brothers, behind the scenes, george galdorisi, relativity mediaMarch 13, 2012No comments
Now for a truly behind-the-scenes look at Act of Valor. We think this "story within the story" about how Act of Valor came to be made in the first place will resonate with you. It is a story that is as intriguing as the movie and novelization.
Like many things that still impact us today, it started on September 11, 2001, a day that is riveted into the consciousness all Americans. That day caused a national catharsis and forced civilian and military leaders within the Department of Defense to begin to rethink how to deal with threats to the Nation in the twenty-first century.
As this re-evaluation began to take shape, one thing became immediately apparent, the U.S. Special Operations Command – or SOCOM – would have a vastly more prominent role in dealing with emerging threats to the United States. As explained by Rear Admiral Denny Moynihan, the Navy's Chief of Information, in a February 19, 2012 article in the New York Times:
Every four years the Defense Department looks at itself and says, "What is it that you need to be moving forward and where do you think you are?" For the Navy and the SEAL community it was, "Hey, you need 500 more SEALs," and that launched a series of initiatives to try to attract more people. This film was one of those initiatives.
For the U.S. Navy SEALs, knowing they would have to have 500 more enlisted SEALs serving in SEAL teams within five years presented a unique challenge. But as all SEALs know, you cannot create SEALs overnight. The U.S. Navy SEALs received an incredibly tough challenge. But true to their nature, they didn't shrink from that assignment. But how tough an assignment was it? That is the challenge that led to movie Act of Valor as well as the subsequent novelization Tom Clancy Presents: Act of Valor.
About Act of Valor – Part 1
Written by George GaldorisiPosted in BlogTags: act of valor, act of valor book, aov book, bandito brothers, george galdorisi, navy seals, relativity media, special opsMarch 13, 2012No comments
Act of Valor, a Bandito Brothers/Relativity Media production, has hit over 3,000 screens these past two weekends, and claimed the number one box office spot (with $24+M) its first weekend ($45+M after ten days). It is not hyperbole to say that Act of Valor is the most unique movie ever made. Those who have seen the movie, and even those who haven't but have heard the "buzz" know that this is the first movie ever starring active duty U.S. Navy SEALs. There is a great deal about the movie on Act of Valor's official website at: http://actofvalor.com/. This post, and two to follow, will take you inside and behind-the-scenes to understand the "story within the story" about how this incredible movie came to be made.
We'll also share how this first-of-a-kind movie spawned a novelization, Tom Clancy Presents: Act of Valor. More faithful to the movie than most novelizations, the book has enjoyed unprecedented success because it is tied so closely to the movie. And success begets success, Tom Clancy Presents: Act of Valor has enjoyed several months on both the New York Times and Publisher's Weekly mass market paperback best-seller lists, rising as high as #4 on both lists and moving into its second printing only six weeks after its initial publication date.

It is not hyperbole to say that Act of Valor is the most unique movie ever made. In much the same fashion, the novelization of this movie, Tom Clancy Presents: Act of Valor is also a unique novel. The book was published on January and has enjoyed a steady presence on the New York Times best-seller list, residing in the top-ten for an extended period. It has also been recognized with the Military Writers of America Book Award in the Thriller/Mystery category. you can visit Amazon.com to pick up your own copy.
While some novelizations bear little resemblance to the movies they purport to 'novelize,' due to our close coordination with Act of Valor directors Mike 'Mouse" McCoy and Scott Waugh, as well as our first-person association with members of the Navy Special Warfare community, Tom Clancy Presents: Act of Valor is truly aligned with the movie Act of Valor and the two are virtually inseparable. This reader/viewer's reaction is typical:
I was really glad I had read the book before I saw the movie. They did such a good job of pulling things together in the book. I think the movie is even more enjoyable after reading the book. I also liked how the book developed the family.

Music by George F. Handel from his "Messiah"
Piano/Organ and Soprano Voice
The Air for soprano "I know that my Redeemer liveth" draws from both Job and Paul. It begins with the "ascending fourth", a signal observed by musicologist Rudolf Steglich as a unifying motif of the oratorio, on the words "I know", repeated almost every time these words appear again. "For now is Christ risen" is pictured in a steadily rising melody of more than an octave.

BakerCorp specialize in tank, pump, filtration and trench shoring rental. Founded in 1942, they provide application expertise and equipment rental to a growing number of industries. Their core systems are IBM i based. They run Rentalman from Wynne Systems, which has been heavily modified and customized for their specific business needs.
BakerCorp management realized that the field staff were struggling to get easy access to equipment, customer and inventory information, which is a vital part of their job. Not only was it inefficient, it was also negatively affecting customer service.
They either had to dial in by cell phone to speak to someone at the head office (during California business hours), or boot up a laptop, get internet access to the back-end system, and then run a 5250 emulator to directly access the data.
Since all the data and business logic that needed to be accessed resided on the IBM i, they set about looking for a solution that would leverage the existing RPG application, and allow secure and real-time access from a tablet device.
BakerCorp selected newlook and lookserver from looksoftware to reface the existing Rentalman application and provide a modern graphical interface for the tablet. At first, they selected an Android based device, but after some initial comparison tests with an iPad, they found that the iPad provided a more reliable and secure connection, and a better overall experience.
Working with a looksoftware consultant, they designed the new interface to be as intuitive and easy to use as possible. Unnecessary screens were removed, and they made extensive use of icons to take advantage of the touch-based interface. "We needed something up and running quickly. It only took 10 days of effort to get our initial version ready for delivery," explained Denise Brunner, Director of Telecom and Wireless Solutions.
To ensure the connection is secure, they utilize a VPN between the iPads and the internal network. "We 'Bakerized' the application so it has a consistent appearance with our website and corporate color scheme" explains Denise.
They initially deployed the application to 60 users, and Brunner said that training the users took very little time. "It's amazing how quickly the users learned to navigate the iPad application," she said.
Initial feedback was extremely positive. Users can access the system at any time and from almost anywhere using their iPad's 4G cellular and Wi-Fi connectivity options.
BakerCorp has since expanded the number of users to 175. It has been reported that each user is saving around an hour a day by using the iPad. "The users are not only saving significant time, they love using the new application," explained Brunner.
SummaryChallenge: BakerCorp wanted to provide field staff with better access to equipment, and to customer and inventory information stored on IBM i.
Solution: BakerCorp refaced their existing application and provided a modern graphical interface for tablets. They also ensured a secure connection through VPN between tablets and the corporate network.

Long before Snookie and the Jersey Shore we're a hit, Scott Backman spent his summers making his own waves with his two brothers, Jeremy his twin, and Jonathan his younger twin, at the shore. Not sure if it was the brotherly head butts or his infatuation with Nickelodeon's "You Can't Do That On Television," Scott soon found himself hooked in his own fantasy to be a comedian.
Proud member of the Mount Olive High marching band (still no sign he was gay?), swim team (for the uniforms) and track team (for the hot legs), Scott spent his weekends driving a red Pontiac Firebird (not so gay) fist pumping and cruising the strip malls (we'll let Scott define cruising when we chat)!
Roll forward to present day. Besides his comedic and acting abilities, he's written a book that transformed his life (we'll get the details), and is an avid Irish Step, Swing Dancing, Internet Ordained Minister (now that's funny)!
So a lot of funny things happen on the way to being gay…and some not so funny. But you'll just have to listen to get the real scoop!
Check out funny man Scott Backman!

Homeowners yearn for beautiful outdoor spaces without the hassle of upkeep. With the rise of multifunctional landscape design and automated processes, consumers can spend more time enjoying their landscapes than ever before. The National Association of Landscape Professionals' 2019 landscape trends reflect current lifestyle preferences as well as innovations happening in the industry that are transforming landscapes across the country.
Functional elements are no longer a perk, but rather a necessity in today's landscapes, as consumers desire stunning outdoor features that have been cleverly designed to serve a dual tactical purpose. An edible vertical garden on a trellis that acts as a privacy fence, a retaining wall that includes built-in seating for entertaining, and colorful garden beds that divide properties all combine function and style.
The latest technology and equipment allow tasks to be more streamlined and environmentally efficient than ever before. Robotic lawn mowers continue to rise in popularity among both homeowners and landscape professionals, and programmable irrigation systems and advanced lighting and electrical systems are a few ways outdoor spaces are becoming extensions of today's smart homes. Homeowners relish knowing that these technological advancements afford them with more time to relax and enjoy their outdoor spaces.
A staple of landscape design for years, pergolas constructed of wood or composite material are now becoming more sophisticated with major upgrades, including rolldown windows, space heaters, lighting and sound systems. When paired with a luxury kitchen, seating area or fire feature, pergolas can become the iconic structure for outdoor sanctuaries.

Hi, I\'m Olivia! I am a 20-year-old student at UBC with a limited background in babysitting. In high school, I volunteered at the Boys and Girls Club, where I helped children with homework, art projects, and played various games. I also spent a month working with physically disabled infants and children in a private orphanage in China. Most days were spent playing and reading with the children, taking them to local parks, and helping the toddlers with skills like learning to walk and speak. It was there that my love for children really took shape!
My interests include theatre, fashion, and reading. I love arts and crafts as well as creating stories, and playing outside. I am trained in CPR and first aid. I am also a licensed driver with a car. I am hoping to expand and grow in my experience in childcare.

Jeannette Rothensies Johns
Born May 19, 1916
Jeannette Rothensies Johns, age 98, of Hockessin, DE, passed away peacefully on Thursday, January 8, 2015, at Cokesbury Village where she resided for over 30 years.

SC county pays $7.1M to protect plantation from development

SC nuclear reactor shut down over small coolant system leak
MOUNT PLEASANT, S.C. (AP) — A South Carolina county has paid $7.1 million to protect a nearly 340-year-old plantation from development.
The Post and Courier reports Charleston County now owns development rights to Boone Hall Plantation, which covers about 600 acres in Mount Pleasant. The property is now under a conservation easement, limiting its use without changing its ownership. Co-owner Willie McRae says it's a "perpetual agreement" to never develop the land and aligns with the wishes of the McRaes, who have owned it since the 1950s.
He says the Charleston County Greenbelt Fund and S.C. Conservation Bank money will go toward improving the land and creating a foundation to run it after the family is gone. The nonprofit Lowcounty Land Trust says the McRaes declined an estimated $21 million by not selling to developers.

$430,000 FOR THE DEATH OF A 93-YEAR-OLD GRANDMOTHER.
$2.3 MILLION FOR THE DEATH OF A SINGLE FATHER OF ONE.
HOW THE LAW VALUES DEATH
Petrillo and Goldberg recently had two death cases settle, one for $430,000.00 for a 93 year old grandmother and one for $2.3 million for the death of a single father of one. So, the question inevitably arises, "How does the law value death?"
"There are basically three ways," said Scott M. Goldberg, Esquire, lead trial counsel for Petrillo & Goldberg. "The first level of value deals with the loss suffered personally by the decedent before they die." This includes the value of pain, suffering, disability or other damages that a person suffers before they die.
We must ask and consider questions such as "How long did the person suffer before they died" and "What was the compensable value of this suffering before they passed on?" added Goldberg.
Often traumatic death comes quickly and mercifully within moments or even seconds. Accordingly, Petrillo & Goldberg will utilize experts to determine how much conscious pain and suffering occurred before death. "This includes both the length and time and the level or degree of suffering," said Goldberg
"We continually endeavor to compassionately and zealously fight for the rights of those wrongfully damaged or injured by the negligence or fault of others. This is what we do."
The second value that the law permits in death cases deals with economic loss to dependents of the decedent resulting from their death.
"This is probably the greatest distinguishing factor in evaluating death cases," said Goldberg. The law considers how much the decedent would have earned over the rest of his or her life, how much of this income would have been used to benefit dependent family members and what the present value of this economic loss calculates to.
"This second factor in evaluating death cases deals strictly with numbers," added Goldberg. "So, while we use medical testimony to establish the value of conscious pain and suffering, we use economists to determine the future economic loss to loved ones resulting from a wrongful death case," explained Goldberg.
The third factor deals with emotional losses stemming from a death claim. "Here we ask the painful question of the value to family members of the loss of the companionship, love, advice, guidance, encouragement and support resulting from their loved one's death," said Goldberg. "Basically, the closer the relationship and the stronger the bond, the higher the value," Goldberg explained.
"We hope that you never need to know any of this information, personally," concluded Goldberg. "These are some of the most difficult claims to evaluate and explain to grieving family members left behind. However, we continually endeavor to compassionately and zealously fight for the rights of those wrongfully damaged or injured by the negligence or fault of others," said Goldberg. "This is what we do."
I have dealt with other law firms, and there is no comparison. It is an honor to know you and I must say, that I have the highest regard for your integrity.

Biden Speaks with Macron For the First Time Since France Recalled Its Ambassador to the US
Joe Biden spoke to French President Emmanuel Macron on Wednesday for the first time since France recalled its ambassador to the US.
The government of French President Macron announced last Friday afternoon it was recalling their ambassadors to the United States and Australia for consultations in the wake of a defense agreement with the U.S., Australia and the United Kingdom that shut out France and cancelled a multi-billion dollar submarine deal between France and Australia.
This is the first time France has recalled its U.S. ambassador in the well over 200 years of close relations dating to France's support for the American Revolution.
France was angry after they learned about Joe Biden's unilateral decision to freeze France out of the deal with Australia.
France learned about the deal in the media.
Joe Biden didn't even contact France about the deal ahead of time, a move the country's Foreign Minister Jean-Yves Drian blasted as "unpredictable."
According to the White House, Joe Biden called Macron.
"The two leaders agreed that the situation would have benefitted from open consultations among allies on matters of strategic interest to France and our European partners," a White House readout of the call read.
Macron agreed to send the French Ambassador back to Washington next week.
