Colliers International | No. 6 Top Workplaces, midsize companies
By Joy Vann
A culture of collaboration and opportunities to socialize outside of work are a couple of things that make Colliers International one of the top places to work in Hampton Roads.
The commercial real estate services provider has earned the Top Workplace distinction seven times, but this is its first year as part of Colliers International. Before Jan. 1, the company operated as CB Richard Ellis of Virginia Inc., an affiliate of CBRE Inc.
Perry Frazer, executive vice president and managing director of the Colliers office in Norfolk, summed up the company's culture as "collaborative, fun with high expectations."
Chief human resources officer Jenny Leigh described the work environment as productive and friendly.
"It has a very warm, engaged family feel. Even though we have some 400 or so employees, it operates like a small family place and we've maintained that small family-kind of feel in the culture, even as we've grown," she said.
She said that in addition to the standard onboarding process, the company employs a mentorship-based orientation model that even seasoned hires go through.
"On the brokerage side of our company, they have a very thorough two-year development plan that they go through with a dedicated mentor for their specialty area and it's similar on the property management side," she said.
Leigh said there are several ways employees who perform outstanding work are recognized.
"We allow our employees to participate in community-based philanthropy during their work hours, which many of our employees consider a recognition as well. Not a whole lot of companies let you do that on work time anymore," she said.
"There is also the Extra Mile Bonus. It's a gift card policy where anybody that is called out by an employee or a customer or a client, for anything that they feel is something above and beyond, we literally approve it and walk over with the card and hand it to the person. We love that."
The company's community involvement is wide-ranging, focusing on causes that employees already support. In addition to holding coat and school supply drives, Colliers supports the food bank, the SPCA and the Leukemia and Lymphoma Society.
"From a policy perspective, we encourage our employees to participate in the community, whether it's coaching sports or participating in nonprofits or donating their time to boards," Frazer said.
Frazer, who has been with the company for 24 years, said it has a high employee retention rate with very little turnover.
"One of the things we're proud of, from a brokerage perspective, is that our tenure is extremely long," he said. "We tend to have brokers, once they get over that three- to four-year threshold that can be challenging — we tend to have them stay. And I would argue that in the last five to 10 years, I can't think of a broker that has actually left us to go to work for a competitor."
Leigh added the Norfolk office recently participated in an employee engagement survey and that it performed well not just within the company, but also compared to the global commercial real estate industry data.
Some of that employee engagement may result from fun perks, like a company picnic, closing at 3 p.m. on Fridays without a pay deduction and casual Friday fundraisers.
"We do things internally and externally for employee engagement like Thirsty Thursday — once a month in our office where we have a little happy hour and get everybody away from their desk to get everybody together to talk about non work-related stuff," Frazer said.
He said the company's top goal is to take care of existing employees and clients and he anticipates the company will continue its growth in lines of business as well as geography.
"I wouldn't be surprised to see us grow outside of our Hampton Roads and Richmond markets over the course of the next 12 months," he said. "So, I think geographic growth will be something hopefully people will see. And we're always looking to add the right people in the right areas to support our clients and customers."
Colliers' industry-leading platform provides unparalleled service to meet any client requirement from acquisition financing, investment sales, real estate portfolio management, to leasing commercial office, industrial and retail space. Its professionals serve the diverse needs of property owners, investors, corporate clients, institutions and tenants. It is committed to helping clients foresee the landscape ahead and seize real estate opportunities that match their needs.

Ты́лич (, ) — село в Польше, находящееся на территории гмины Крыница-Здруй Новосонченского повята Малопольского воеводства.

География
Село находится при слиянии реки Мышинка и ручья Мохначка в 6 км от города Крыница-Здруй, в 35 км от города Новы-Сонч и в 108 км от Кракова. Село расположено на границе двух горных систем Низкие Бескиды и Сондецкие Бескиды. Около Тылича проходит дорога 75. В окрестностях села находится не существующий пограничный пункт Мышинка-Куров.

Экономика
В селе действует государственное сельскохозяйственное предприятие «Państwowy Ośrodek Hodowli Zarodowej Tylicz» и частные предприятия по добыче и розливу минеральной воды.

В окрестностях села находятся многочисленные горнолыжные туристические базы, школы верховой езды.

Через Тылич проходит туристический маршрут.

История
В XIII веке здесь существовало селение под названием Орнава. В 1336 году Орнава перешла под королевское право. В 1363 году село перешло под магдебургское право и стало называться городом Мястко. В 1391 году Мястко перешёл в собственность краковского епископа. В 1612 году Мястко получил собственный герб. В XVI веке Мястко пришёл в упадок и стал называться как Тылич. С 1781 года в Тыличе стали селиться евреи. В 1935 году статус Тылича был понижен до села

До конца Второй мировой войны большинство жителей села составляли лемки. В 1946—1947 годах большинство жителей села были переселены во время операции «Висла» на западные территории Польши. В 1956 года в Тылич возвратилось несколько десятков лемковских семей. В настоящее время большинство населения села составляют поляки.

В 1973 году Тылич стал административным центром гмины Тылич, которая в 1975 году была упразднена и Тылич перешёл в гмину Крыница-Здруй.

Достопримечательности
 Церковь святых Петра и Павла — католическая церковь;
 Церковь святых Космы и Дамиана — бывшая грекокатолическая церковь.

RUBBISH: José Railton with two-year-old daughter Poppy outside their Sallowbush Road home. Picture: HELEN DRAKE.
INCONSIDERATE parkers are again causing a stink in Huntingdon.
José Railton said council lorries were often unable to get through to empty the bins behind her house because of the number of parked cars.
She said about 20 bins were left at the collection point in Bernard Close, near her back garden.
Mrs Railton, of Sallowbush Road, said the bin collectors often had to return up to five times before they could get through.
With cars frequently parked along one side of Bernard Close and garage access required on the other side, the collection lorries were unable to swing round to get close enough to the bins.
She said: "It's bad enough when the refuse lorries can't get through – but what about if the emergency services needed access?
Mrs Railton, 32, contacted Huntingdonshire District Council, and she said it had tried sending a smaller lorry but had still found the road blocked.
She and her husband Jon, who have a two-year-old daughter, Poppy, were also concerned at the public health hazard of the bins being left and had taken rubbish to the tip themselves.
She said: "The bins are right at the back of the house and we often use the back for going in and out of the house.
"People just leave their rubbish there until the bins get emptied.
The couple have lived in Sallowbush Road for five-and-a-half years but said this was the worst the situation had been.
She said: "Imagine those bins in summer – it's going to be horrendous.
A spokesman for HDC said the council was aware of the problem and was attempting to resolve it.

\section{Introduction}
Reservoir computing is a brain-inspired machine-learning technique that employs a data-driven dynamical system.
The framework was proposed as Echo-State Networks~\cite{Jaeger_2001,Jaeger_2004} and Liquid-State Machines~\cite{Maass_2002}, and it has been found to be effective in the inference of a future such as time-series, frequency spectra
and the Lyapunov spectra~\cite{Antonik_2018,Ibanez_2018,Inubushi_2017, Zhixin_2017,Pathak_2018, Pathak_2017,Verstraeten_2007}.

A reservoir is a recurrent neural network whose internal parameters are not adjusted to fit the data in the training process.
Only an output layer is trained.
Therefore,
the total computational costs are relatively low in comparison
with many other machine learning techniques having the same dimensional neural networks.
Many physical phenomena including a fluid flow are deterministic, and thus can be described by a high-dimensional dynamical system, even thought they have a complex behavior.
That is why the reservoir computing with a high-dimensional neural networks can be useful for the construction of a model for such a phenomenon.

In our previous paper~\cite{nakai_2018}, we infer both microscopic and macroscopic behaviors of a three-dimensional chaotic fluid flow using reservoir computing.
We presented two ways of inference of the complex behavior: the first, called partial inference, requires continued knowledge of partial time-series data during the inference as well as past time-series data, while the second, called full inference, requires only past time-series data as training data. For the first case, we are able to infer long-time motion of microscopic fluid variables. For the second case, we showed that the reservoir dynamics constructed from only past data of energy functions can infer the future behavior of energy functions and reproduced the energy spectrum.

In various experiments and observations of high-dimensional complex phenomena,
there are usually much smaller number of measurements than the Lyapunov dimensions of the attractor.
Even in such cases, we can efficiently
construct a dynamical model by generating high-dimensional input data $\mb{u}$ for the reservoir computing by using the delay-coordinate~\cite{nakai_2018,Embedology,Takens}.

The current paper focuses on the model construction and the full-inference of a macroscopic variable, the Taylor microscale Reynolds number, when the scalar time-series is accessible as measurements.
We evaluate the model in many ways, and discuss details of the appropriate choice of the delay-coordinate created from the single observable.
This will be useful for readers who wish to construct a reservoir model by themselves.

After reviewing the procedure of the reservoir computing in Sec.~\ref{reservoir} and
the generation of time-series data of a fluid flow in Sec.~\ref{fluid},
we show that the constructed reservoir model recovers various properties of a fluid flow obtained from the Navier-Stokes equation in Sec.~\ref{inference}.
We investigate the effective choice of delay-coordinate in order to construct a model
in Sec.~\ref{delay}.
We summarize our results in Sec.~\ref{summary}.

\section{Reservoir computing}\label{reservoir}
Reservoir computing is recently used in the inference of complex dynamics~\cite{Ibanez_2018,Lu_2018,Zhixin_2017,Pathak_2018, Pathak_2017}.
It focuses on the determination of a linear function from the reservoir state vector to variables to be inferred
(see eq.~(\ref{eq:output2})).
Here we review the outline of the method \cite{Jaeger_2004,Zhixin_2017}.
In this paper, we construct a model dealing with so called full-inference, in which there is no observable data in the inference phase \cite{nakai_2018}.  \\
\indent We consider a dynamical system
\begin{equation*}
\frac{d\mb{\phi}}{dt}=\mb{f}(\mb{\phi}),
\end{equation*}
together with a pair of $\phi$-dependent, vector valued variables
\begin{equation}
\mb{u}=\mb{h}_1(\mb{\phi})\in \mm{R}^{M}
~~\text{and}~~
\mb{s}=\mb{h}_2(\mb{\phi})\in \mm{R}^{M}.\label{eq:input}
\end{equation}
We seek a method for using the
knowledge of $\mb{u}$ to determine an estimate $\Hat{\mb{s}}$ of $\mb{s}$ as a function of time when direct measurement of $\mb{s}$
is not available.
We have a knowledge $\mb{u}$ and  $\mb{s}$ during the {\bf training phase} for $t\le T$,
$\mb{u}$ and  $\mb{s}$  are unknown during the {\bf inference phase} for $t>T$.
Therefore, $\mb{u}$ during the inference phase is replaced by $\Hat{\mb{s}}$ in the previous step. See eq. \eqref{eq:full-reservoir} for the detail.
\allblack\\
\indent The dynamics of the {\bf reservoir state vector}
\begin{equation*}
\mb{r}\in \mm{R}^{N}~(N \gg M),
\end{equation*}
 is defined by the neural network
\begin{equation}
	\mb{r}(t+\Delta t)=(1-\alpha)\mb{r}(t)+\alpha \tanh(\mb{A}\mb{r}(t)+\mb{W}_{\text{in}}\mb{u}(t)
	),\label{eq:reservoir}
\end{equation}
where $\Delta t$ is a relatively short time step,
and
\begin{equation*}
\tanh(\mb{q})=(\tanh(q_1), \tanh(q_2),\cdots,\tanh(q_N))^{\text{T}},
\end{equation*}
for a vector $\mb{q} = (q_1,q_2,\cdots,q_N)^{\text{T}}$.
Here,  $\text{T}$ represents  the  transpose of a matrix.
The matrix $\mb{A}$ is a weighted adjacency matrix, and the $M$-dimensional
input $\mb{u}$ is fed in to the $N$ reservoir nodes via a linear input weight matrix denoted by $\mb{W}_{\text{in}}$.
The parameter $\alpha$ ($0<\alpha\le 1$)
adjusts the nonlinearity of the dynamics of $\mb{r}$,
and is chosen depending upon the complexity of the dynamics of measurements and the time step $\Delta t$. \\
\indent Each row of $\mb{W}_{\text{in}}$ has one nonzero element, chosen from a uniform distribution on $[-\sigma,\sigma]$.
The matrix $\mb{A}$ is chosen from a sparse random
matrix in which the fraction of nonzero matrix elements is $D/N$,
so that the average degree of a reservoir node is $D$.
The $D$ non-zero components are chosen from a uniform distribution on $[-1, 1]$.
Then we uniformly rescale all the elements of $\mb{A}$ so that the largest value of the magnitudes of its eigenvalues becomes $\rho$. \\
\indent The output, which is a $M$-dimensional vector, is taken to be a linear function of the reservoir state vector $\mb{r}$:
\begin{equation}
	\Hat{\mb{s}}(t)=\mb{W}_{\text{out}}\mb{r}(t)+\mb{c}.\label{eq:output}
\end{equation}
The reservoir state vector $\mb{r}$ evolves following eq.~(\ref{eq:reservoir}) with input
$\mb{u}(t)$,
starting from random initial state $\mb{r}(-T_0)$ whose elements are chosen from $(0, 1]$ in order not to diverge,
where $T_0=L_0\Delta t~(\gg 1)$ is the transient time for $\mb{r}(t)$ ($t>0$) to be on the attractor.
We obtain $L=T/\Delta t$ steps of reservoir state vectors $\{\mb{r}(l\Delta t)\}_{l=1}^{L}$ by iterating eq.~(\ref{eq:reservoir}),
 while we record the variables $\{\mb{s}(l\Delta t)\}_{l=1}^{L}$ by using  the actual measurements from eq. (\ref{eq:input}) for the training phase.
\allblack
\\
\indent{\bf Determination of $\mb{W}_\text{out}$ and $\mb{c}$.}
\indent
We determine $\mb{W}_\text{out}$ and $\mb{c}$
so that the reservoir output  $\Hat{\mb{s}}$ (eq. \eqref{eq:output}) approximates the measurement $\mb{s}$ for $0< t \le T$~(training phase), which is a training process in the reservoir computing.
We determine them  by minimizing the following quadratic form with respect to $\mb{W}_\text{out}$ and $\mb{c}$:
\begin{equation}
\displaystyle\sum^{L}_{l=1} \|(\mb{W}_\text{out}\mb{r}(l\Delta t)+\mb{c})-\mb{s}(l\Delta t)\|^2
+\beta[Tr(\mb{W}_\text{out}\mb{W}^{\text{T}}_\text{out})],\label{eq:minimize}
\end{equation}
where $\|\mb{q}\|^2=\mb{q}^{\text{T}} \mb{q}$ for a vector $\mb{q}$,
and the second term is a regularization term introduced to avoid overfitting
$\mb{W}_\text{out}$ for $\beta \ge 0$.
When the training is successful, $\Hat{\mb{s}}(t)$ should approximate the desired unmeasured quantity $\mb{s}(t)$ for $t>T$~(inference phase).
Following eq.~(\ref{eq:output}), we obtain
\begin{equation}
	\Hat{\mb{s}}(t)=\mb{W}^*_\text{out}\mb{r}(t)+\mb{c}^*,  \label{eq:output2}
\end{equation}
where $\mb{W}^*_\text{out}$ and $\mb{c}^*$ denote the solution for the minimizers
of the quadratic form~(\ref{eq:minimize}):
\begin{align}
	\mb{W}^*_\text{out}&=\delta\mb{S}\delta\mb{R}^{T}(\delta\mb{R}\delta\mb{R}^{T}+\beta\mb{I})^{-1}, \label{eq:wout-c1}\\
	\mb{c}^*&=-[\mb{W}^*_\text{out}\overline{\mb{r}}-\overline{\mb{s}}], \label{eq:wout-c2}

In the inference phase for $t>T$, eq.(\ref{eq:reservoir}) is written as
\begin{equation}
\mb{r}(t+\Delta t)=(1-\alpha)\mb{r}(t)+\alpha \tanh(\mb{A}\mb{r}(t)+\mb{W}_{\text{in}}\Hat{\mb{s}}(t)),\label{eq:full-reservoir}

The main variables and matrices in the reservoir computing are summarized in Table~\ref{tab:variable}.

\indent {\bf Normalization of a variable.}
In order to consider the effect of all the variables equally, we take the normalized value $\tilde{x}(t)$ for each variable $x(t)$, which will be used in the procedure of our reservoir computing:
\begin{equation*}
\tilde{x}(t)=[x(t)-X_1]/X_2,
\end{equation*}
where $X_1$ is the mean value and $X_2$ is the variance.
When  we reconstruct $x(t)$ in the inference phase from $\tilde{x}(t)$,
we employ $X_1$ and $X_2$ obtained in the training phase.
 Due to the normalization we can avoid adjustments of $\sigma$.

{\bf Parameter choice.} We apply a method of reservoir computing described above in order to construct a model.
The sets of parameter values used are shown in Table~\ref{tab:parameter}.

\section{Generation of a fluid flow data}\label{fluid}
Modelling and inference of a fluid flow are important problems in many areas~\cite{Clark_2018,nakai_2018}.
In this paper, we construct a model for a macroscopic variable of a fluid flow,
especially the time-dependent ``Taylor microscale Reynolds number'' which reflects the degree of complexity in the fluid flow.
We generate training data by the direct numerical simulation of the Navier-Stokes equation,
which is also used for the reference data in the inference phase in order to evaluate the constructed reservoir model.
It should be remarked that the Navier-Stokes equation and its physical property are not considered at all when constructing a reservoir model.

{\bf Generation of training data.}
In order to generate measurements of the reservoir computing,
we employ the direct numerical simulation of the incompressible three-dimensional Navier-Stokes equation
under periodic boundary conditions:
	\begin{align*}
  \begin{cases}
		\partial_t v -\nu \Delta v
			+(v \cdot \nabla) v+\nabla \pi=f,~\nabla \cdot v=0, ~\mathbb{T}^3\times(0,\infty),\\
v\big| _{t=0}=v_0\quad \text{with $\nabla \cdot v_0=0$}, ~~~~~~~~~~~~~~~~~~~~\mathbb{T}^3,
  \end{cases}
	\end{align*}
where $\torus=[0,1)$, $\nu>0$ is a viscosity parameter, $\pi (x,t)$ is pressure, and $v(x,t)= (v_1(x,t),v_2(x,t),v_3(x,t))$ is velocity.
Throughout this paper, we set $\nu = 0.058$, under which the fluid flow shows an intermittent behavior between laminar and bursting states. See such a behavior in the bottom panel of Fig.~\ref{fig:full-macro}.
We use the Fourier spectral method~\cite{ishioka_1999} with $N_0(=9)$ modes in each of three directions, meaning that the system is approximated by
$2(2 N_0+1)^3~(=13718)$-dimensional ordinary differential equations (ODEs).
The ODEs are integrated by the 4th-order Runge--Kutta scheme, and the forcing is input into the low-frequency variables at each time step so as to preserve the energy of the low-frequency part.
See~\cite{ishioka_1999,nakai_2018} for the details.

{\bf Reynolds number $R_{\lambda}$.}
We focus on the time-series of the Taylor microscale Reynolds number,
a macroscopic variable representing the degree of complexity of a fluid flow.
The total energy $E(t)$ is defined by
\begin{equation*}
E(t)=\sum_{\kappa \in D} \sum_{\zeta=1}^{3} \left(
\mathcal{F}_{[v_{\zeta}]}(\kappa,t)
\right)^2,
\end{equation*}
where
\begin{equation*}
	\mathcal{F}_{[v_{\zeta}]}(\kappa,t):= \dfrac{1}{(2\pi)^3} \displaystyle\int_{\mathbb{T}^3}
			v_{\zeta}(x, t)
		e^{-i(\kappa\cdot x)}dx \quad(\zeta = 1,2,3),
\end{equation*}
and $D=\{(\kappa_1,\kappa_2,\kappa_3) \in  \mathbb{Z}^3 \mid \kappa_1,\kappa_2,\kappa_3 \in [-9,9] \}$.
The Taylor microscale Reynolds number $\check{R}_{\lambda}(t)~$\cite{Ishihara_2003} is defined
as follows:
	\begin{align*}
		\check{R}_{\lambda}(t) := \dfrac{\sqrt{(2/3)E(t)}\lambda}{\nu}
		 = \sqrt{\dfrac{20 E(t)^2}{3\nu \epsilon(t)}},
	\end{align*}
where
\begin{equation*}
\epsilon(t)=2\nu \sum_{\kappa \in D}  \sum_{\zeta=1}^{3} \left|\kappa\right|^2 \left(
\mathcal{F}_{[v_{\zeta}]}(\kappa,t)
\right)^2,
\end{equation*}
 is the average rate of energy dissipation per unit mass
and
\begin{equation*}
\lambda=\left(\frac{15 \nu (2/3)E(t)}{\epsilon(t)}\right)^{1/2},
\end{equation*}
is the characteristic length of a turbulent fluid flow.
The length roughly corresponds to that of an energy input in this study.

In order to get rid of the high-frequency fluctuation, we take the
short-time average
\begin{equation*}
{R_{\lambda}}(t)=\sum_{l=99}^{0}\check{R}_{\lambda}(t-l \Delta t^*)/100,
\end{equation*}
where $\Delta t^*=0.05$ is the time step of the integration of the Navier-Stokes equation.
This helps us to obtain essential low-frequency dynamics of a Reynolds number and construct a model with less computational costs with lower dimension $N$ of the reservoir state vectors.
The averaged Reynolds number ${R_{\lambda}}$ will be called the Reynolds number,
and the time-series generated by the direct numerical simulation in the inference phase
will be called the ``actual data''.
\\

\section{Construction of a model for a macroscopic variable: Reynolds Number}\label{inference}
Using the reservoir computing discussed in Sec.~\ref{reservoir}, we construct a model by training a time-series data
of the Reynolds number ${R_{\lambda}}$ (see Sec.~\ref{fluid}) that shows an intermittent behavior between
laminar and bursting states.
For its purpose a delay-coordinate vector created from a scalar observable is introduced to the input and output variables.

\subsection{Construction}
{\bf Delay-coordinate.}
The choice of variables for the reservoir model is significant.
Here, we introduce an $M$-dimensional delay-coordinate vector of the Reynolds number with a delay-time $\Delta \tau$
as input and output variables $\mb{u}(t)=(u_1(t),u_2(t),\cdots,u_M(t))^{\text{T}}$ and $\mb{s}(t)=(s_1(t),s_2(t),\cdots,s_M(t))^{\text{T}}$ in eq.~\eqref{eq:input}, that is,
\begin{align}
\mb{u}(t)
&=(\tilde{R}_{\lambda}(t), \tilde{R}_{\lambda}(t-\Delta \tau),\cdots,\tilde{R}_{\lambda}(t-(M-1)\Delta \tau))^{\text{T}}, \label{eq:delay}\\
\mb{s}(t)
&=(\tilde{R}_{\lambda}(t), \tilde{R}_{\lambda}(t-\Delta \tau),\cdots,\tilde{R}_{\lambda}(t-(M-1)\Delta \tau))^{\text{T}}. \label{eq:delay2}
\end{align}
The appropriate choice of the {\bf dimension} $M$ and the {\bf delay-time} $\Delta\tau$ of the delay-coordinate will be discussed in Sec.~\ref{delay}.
\\
{\bf Determination of a model.}
Under the parameters listed in
Table~\ref{tab:parameter} and randomly chosen matrices $\mb{A}$ and $\mb{W}_\text{in}$,
 we find a candidate of a reservoir model by fixing $\mb{W}^*_\text{out}$ and $\mb{c}^*$  following the procedure
 explained in Sec~\ref{reservoir}.
 If the candidate passes a certain criteria concerning the short time  inference, the candidate is considered as a model.
 See Sec.~\ref{delay} for the details of the criteria.
Remark that although we can use a training data as some delay components of input data when $t-(M-1)\Delta \tau<T$,
 we do not use any training data in the inference phase.
Hereafter throughout this section, we choose one of the  models, and fix the corresponding  set of values $\mb{A}$, $\mb{W}_\text{in}$, $\mb{W}^*_\text{out}$ and $\mb{c}^*$.

\caption{ {\bf
Inference of a time-series of the Reynolds number of a fluid flow.}
Time-series of $s_1=\tilde{R}_{\lambda}$ is inferred from the reservoir model
in comparison with that of a reference data obtained by the direct numerical simulation of the Navier-Stokes equation
(top left).
The variable $t^\prime ~(= t-T>0)$ denotes the time after finishing the training phase at $t=T$.
The inference errors $\varepsilon_1, \varepsilon_2$ defined by $\varepsilon_1(t)=|\mb{s}(t)-\hat{\mb{s}}(t)|$, and
$\varepsilon_2(t)=|s_1(t)-\hat{s}_1(t)|=|\tilde{R}_{\lambda}(t)-\hat{\tilde{R}}_{\lambda}(t)|$ are shown to
increase exponentially due to the chaotic property
(top right).
In the bottom figure switching between laminar state with a small amplitude fluctuation and bursting state with a large amplitude fluctuation appear in an inferred time-series of $s_1=\tilde{R}_{\lambda}$,
which are observed in the actual time-series.
Remark that the model trajectory shows an intermittent behavior on a chaotic set, but after a long transient it will diverge eventually at
$t^{\prime}\approx290000$.
\allblack
}\label{fig:full-macro}
\end{figure}
\subsection{Evaluation of the model}
We evaluate the constructed reservoir model for the Reynolds number from several points of view
by comparing its property with that of the actual data obtained from the direct numerical simulation of Navier-Stokes equation. \\
{\bf Time-series.}
We confirm that an inference of a time-series of the Reynolds number $s_1=\tilde{R}_{\lambda}$ is successful for some time after finishing the training phase.
The time-series of the inferred variable $\hat{s}_1=\hat{\tilde{R}}_{\lambda}(t)$ ($t>T$) is shown with the actual data
$\hat{s}_1={\tilde{R}}_{\lambda}(t)$ obtained from the direct numerical simulation of Navier-Stokes equation in the top left panel of Fig. \ref{fig:full-macro}.
The failure in the long-term time-series inference is inevitable just due to the sensitive dependence on the initial condition of a chaotic property of the fluid flow.
The two types of errors between the inferred value and the actual one are shown in the top right panel of Fig. \ref{fig:full-macro}.
Moreover, the long-time behavior of $\hat{\tilde{R}}_{\lambda}(t)$ is shown in the bottom panel,
which has qualitatively similar intermittent behaviors to the actual one,  intermittent switching between the state of low amplitude fluctuations (laminar state) and the state of high amplitude fluctuations (burst state).
\\
{\bf Delay Property.}
\allblack
As we employ the delay-coordinate vector for input and output variables of the reservoir computing (eqs.~\eqref{eq:delay},\eqref{eq:delay2}),
the relation $s_1(t) = s_{m}(t+(m-1)\Delta \tau)$ holds for any $m ~(m=2,\cdots,M)$ during the training phase.
The corresponding relation should also be satisfied in the inference phase.
We show the time-series $\hat{s}_1(t)$ and $\hat{s}_{14}(t+13\Delta \tau)$ in Fig. \ref{fig:delay-time-series},
which satisfies the relation $\hat{s}_1(t) \approx \hat{s}_{14}(t+13\Delta \tau)$.
We can confirm that for almost all $t$ the relation $\hat{s}_1(t)\approx \hat{s}_{m}(t+(m-1)\Delta \tau)$ is satisfied for any $m$.
The results imply that our reservoir computing successfully learns the delay property only through training such data.
\begin{figure}[h]
\begin{center}
  \includegraphics[width=0.6\columnwidth,height=0.240\columnwidth]{fig5-a.eps}\\
  \caption{{\bf  Reproducing the delay property which is to be satisfied for the successfully inferred time-series $\hat{\bf s}$.}
  We observe that  for all values of $m=2,\cdots, 14$ and for most $t^{\prime}$, $\hat{s}_1(t^\prime)\approx\hat{s}_{m}(t^\prime+(m-1)\Delta\tau)$,
  although the time-series of only $\hat{s}_1(t^\prime)$ and $\hat{s}_{14}(t^\prime+13\Delta\tau)$ $(7000\le t^{\prime}\le 8000)$ are shown.
  The delay property is reproduced only from the training data.
  }\label{fig:delay-time-series}
  \end{center}
\end{figure}
\\
{\bf Poincar\'e plane.}
We investigate the chaotic set computed from a model trajectory to see whether the inferred chaotic set mimics the actual one.
For its purpose we describe the Poincar\'e plane
in comparison with that computed from a trajectory of the direct numerical simulation of the Navier-Stokes equation with the same time length in the Fig. ~\ref{poincare}.
Although the sections are similar to each other, but they are not very close to each other. This may be because the length of the
intermittent trajectory is not enough to cover various regions especially in the bursting state.
\begin{figure}[h]
\begin{center}
  \includegraphics[width=0.6\columnwidth,height=0.240\columnwidth]{fig3-a.eps}
  \caption{{\bf
  Poincar\'e points on the plane $(s_2,s_3)$ along the trajectory $\Hat{\mb{s}}$ obtained from the reservoir model (red) and $\mb{s}$ from the Navier-Stokes equation (blue). }
The time length of each trajectory is $90000$. The Poincar\'e section is defined by ${s}_{1}=0, ~d{s}_{1}/dt>0$.
Two sections are similar to each other, although a trajectory generated from the reservoir model does not cover some region of bursting states.
The figure suggests that each of the chaotic set is hyper-chaotic, that is the dimension of the unstable manifold is two or higher.}\label{poincare}
  \end{center}
\end{figure}
\\
{\bf Distribution.}
Density distributions computed from two inferred trajectories $\{ \hat{s}_1(t) \}$ and those from two actual trajectories
$\{ {s}_1(t) \}$ are shown in Fig. ~\ref{distribution}.
We can observe that the distributions computed from trajectories of time lengths 5000 are fluctuating, but the inferred distributions
 seem to have similar properties to the actual distributions.
Relatively large fluctuations in distributions for

 $|\hat{s}_1(t) |>1$ should be due to the intermittency.

\begin{center}
  \includegraphics[width=0.65\columnwidth,height=0.240\columnwidth]{fig4-a.eps}\\
  \caption{{\bf Density distributions generated from trajectories for a variable $s_1$ obtained from the constructed reservoir model (reservoir output) and from the direct numerical simulation of the Navier-Stokes equation (actual).}

  Each trajectory with a time-length 50000 has a different initial condition. The distributions are similar to each other in the sense that the peak is taken at $s_1\approx0.2$, and the distribution has relatively long tails.
 }\label{distribution}
  \end{center}
\end{figure}
\\
{\bf The reservoir model can be used to infer time-series of another time-interval.}
We obtained a model just by training the data and it enables us to infer short-time behavior, the shape of an attractor and the density distribution.
Here we confirm that the model constructed using a certain training data has the ability to infer a short-time behavior of the Reynolds number for the totally different time-interval.
In Fig.~\ref{fig:diff-inference}, the inferred time-series is shown in comparison with the actual one.
For this inference we use the same reservoir model as is used in Fig.~\ref{fig:full-macro}, and only change the initial condition.
This figure supports the accuracy of the constructed reservoir model.

 We use the same $\mb{W}_\text{in},\mb{A},\mb{W}^*_\text{out}$ and $\mb{c}^*$ as those used for the model inferring the trajectory in Fig.~\ref{fig:full-macro}.
 But we use  the time-series $s_1(t^\prime)$ for $T_{\text{out}}- T_1<t^\prime<T_{\text{out}}$ as an initial condition, where

 $T_1$ is the transient time for the reservoir state vector $\mb{r}(t)$ to be converged.
 \allblack
In the top panel, switching between laminar and  bursting states is observed in the inferred trajectory.
 The bottom panel is the enlargement of the top panel, and shows that the model has a predictability for $1000<t^\prime<1080$.
 This means that the reservoir model constructed using the training data at a certain time-interval can become the model for another time-interval.

\end{figure}
In Fig. \ref{fig:mult-diff-inference}, by using the same model the inference of time-series of the Reynolds number
 in many different time intervals are shown. For each time-interval, we confirm that the short time inference is successful.
This implies that the obtained model can describe the dynamics of the Reynolds number.

\section{\bf Choice of delay-coordinate.}\label{delay}
\allblack
We use an $M$-dimensional delay-coordinate vector with a delay-time $\Delta \tau$ (eqs.~\eqref{eq:delay},\eqref{eq:delay2}) as input and output variables $\mb{u}$ and $\mb{s}$ in eq.~\eqref{eq:input}.
In this section we investigate the appropriate choice of time-delay $\Delta \tau$ and the dimension $M$.\\
{\bf Time-correlation.}
The auto-correlation function $C({x})$ along a trajectory $\{R_{\lambda}(t))\}$ with respect to the time-difference $x$ is computed by
\begin{align}
C({x}) = \dfrac{\dfrac{1}{J}\displaystyle\sum_{j=0}^{J-1}(R_{\lambda}(t_0+j\Delta t^*)-\bar{R}_{\lambda})(R_{\lambda}(t_0+j\Delta t^*+x)-\bar{R}_{\lambda})}
	{
	\sqrt{\dfrac{1}{J}\displaystyle\sum_{j=0}^{J-1}(R_{\lambda}(t_0+j\Delta t^*)-\bar{R}_{\lambda})^2}
	\sqrt{\dfrac{1}{J}\displaystyle\sum_{j=0}^{J-1}(R_{\lambda}(t_0+j\Delta t^* +x)-\bar{R}_{\lambda})^2}
	},
\end{align}
where
$\bar{R}_{\lambda}$ is the time average of $R_{\lambda}(t)$, $\Delta t^*$ is the time step of the discrete trajectory, and
$t_0$ is an initial  time of a trajectory.
In Fig.~\ref{correlation}, we show the auto-correlation function $C(x)$ for a trajectory $\{R_{\lambda}(t)\}$
with respect to the delay-time $x$.
\begin{figure}[b]
\begin{center}

  	\includegraphics[width=0.48\columnwidth,height=0.240\columnwidth]{fig1b.eps}

  \caption{{\bf
  Auto-correlation function $C(x)$ for a trajectory $\{R_{\lambda}(t)\}$

  with respect to the value of time-delay $x$ (left), and its enlarged figure (right).}
  Auto-correlation function $C(x)$ is shown together with
  the straight lines $\pm0.3,\pm0.5$ (left panel), and $0.3,0.7$ (right panel).
  Each of the different colors represents $C(x)$ computed from a trajectory from a different initial condition with time-lengths 5000.
  The difference is mainly due to the intermittent property of the dynamics.
  In the left panel the envelope $C_e(x)(=\exp(-x/60))$ is shown to go below 0.5 when $x \approx 40$,  and also go below 0.3 when $x \approx 75$.
 From the right panel $C(x)$ is shown to go below $0.7$ at the first time, when $x \approx  3.0$,
and go below $0.3$ at the first time, when $x \approx 5.0$.
}
  \label{correlation}
  \end{center}
\end{figure}
It is observed from Fig.~\ref{correlation}~(right) that as $x$ increases from 0,
$C(x)$ goes below 0.7 and 0.3 when $x\approx 3.0$ and $5.0$, respectively.
\\
\indent The observation suggests that the value of the delay-time $\Delta \tau$ is to be chosen around $3.0$-$5.0$.
If $\Delta \tau< 3.0$, the consecutive two components of a delay-coordinate vector in \eqref{eq:delay},
$R_{\lambda}(t)$ and
$R_{\lambda}(t-\Delta \tau)$  behave too similarly, and if $\Delta \tau> 5.0$, the consecutive two components behave too differently,
and some dynamics to be captured may be missing.

{\bf Delay-time and dimensions.}
Based on the above implication about the auto-correlation function in Fig.~\ref{correlation},
 we investigate the effective delay-time $\Delta \tau$ and dimensions $M$.
We focus on the delay-time $\Delta \tau \approx 3.0$-$5.0$ in Table \ref{tab:parameter-delay}.
We infer time-series of the Reynolds number $R_{\lambda}(t)$ (actually its normalized value $\tilde{R}_{\lambda}(t)$) using the procedure in Sec.~\ref{reservoir}
by employing the delay-coordinate in eq.~\eqref{delay}.
We tried 8160 cases for each set of parameters $(\Delta \tau,M)$, for which matrices $\mb{A}$ and  $\mb{W}_\text{in}$ are chosen randomly, and the number of successful cases are counted in TABLE \ref{tab:parameter-delay}.
We say that the inference of $s_1(t^\prime)$ ($t^\prime = t-T>0$)  is successful if the conditions
\begin{align}
\begin{cases}\label{eq:defErrer}
 \text{(i) the time average along } |\hat{s}_1(t^\prime)|<3 \text{ for } t^\prime \le 3000,\\
 \text{(ii) the error }\varepsilon_2(t^\prime)=|s_1(t^\prime)-\hat{s}_1(t^\prime)|=|\tilde{R}_{\lambda}(t^\prime)-\hat{\tilde{R}}_{\lambda}(t^\prime)|<e_{60} \text{ for all }t^\prime\le 60, \\
 \text{(iii) the error }\varepsilon_2(t^\prime)<e_{90} \text{ for all }t^\prime\le 90,
\end{cases}
\end{align}
hold, where the criteria $(e_{60},e_{90})$ are set as (a)$(0.14,0.30)$ and (b)$(0.13,0.17)$.
Remark that the condition (i) is given so as to get rid of a candidate which diverges within a short time,
as $|s_1(t^\prime)|<3$ for almost all $t$ even in the bursting region.
For each case we use the same training data as in Fig.~\ref{fig:full-macro}.

It is observed that the delay-time $\Delta \tau$ and the dimension $M$ of the delay-coordinate are chosen so that  $\Delta \tau\approx 4.0$-$4.5$, and $M\Delta \tau\approx 55$-$60$,
which correspond to $C(\Delta \tau)\approx0.45$-$0.55$ and its envelope $C_e(M \Delta \tau) \approx0.35$-$0.40$, respectively (see the left panel of Fig. \ref{correlation}  for   the envelope $C_e$).
For $\Delta\tau=4.0$ and $M=14, 15$ by computing 16 times more cases,  we confirmed that  the rate of successful trials does not change much.
In addition, even when we change the value of $N$ such as $1000$ or $3000$,
we obtain almost the same results.

\section{Summary and discussion}\label{summary}
By training a time-series data of a macroscopic quantity the Reynolds number of a fluid flow, we construct a closed form system  describing its intermittent behavior between laminar and bursting states.
For the model construction, we do not use the knowledge of a physical process.
We evaluate the obtained model in many ways. In particular, the model is confirmed to have a time-series predictability in many time intervals.\\
\indent In order to construct a model from a scalar time-series data, we introduce a time-delay coordinate.
From our investigations, the time-delay should be chosen to be the lowest value $\Delta\tau (>0)$
	so that the auto-correlation function $C$ is $0.45<C(\Delta\tau)<0.55$ at the first time,
	and that the dimension $M$ of the delay-coordinate  should be chosen so that the envelope $C_e$ of the auto-correlation function
	$C$ is $0.35<C_e(M\Delta\tau)<0.40$.\\
\indent It should be remarked that the obtained reservoir model has a chaotic set on which a trajectory approximates the actual one,
but the set is not an attractor.
This may be due to the lack of a training data, especially in the bursting state. The clarification is remained as a future study.

If you're looking to help yourself or someone you love struggling with alcoholism or drug abuse in Show Low, AZ, Rehabs.com provides a massive Internet database of executive private clinics, as well as myriad other options. We can help you in locating addiction care centers for a wide variety of addictions to alcohol, Oxycodone, heroin or any addictive drug. Search for a highly-rated rehabilitation clinic in Show Low now, and get rolling on the road to a sober life.
Getting sober from Luminal, Biocodone, alcohol or other addictive drugs you or your loved one is addicted to takes an specifically-tailored treatment schedule. Two options of addiction treatment clinics in Show Low can help you succeed: either Residential or Outpatient Rehab. Residential therapy offers enduring benefits with longer stays in a top rehab facility. Outpatient treatment options may be convenient, but lack the stability and capability of 3 month programs to get clean and sober. Ultimately, you are in control of your decision, and we are here to help you choose the one that will be best for you.
Isolating yourself from the setting of the abuse issue can help eradicate interruptions and temptations that prevent you from staying clean. When viewing rehabilitation as a restorative retreat, addicts will find executive private centers in cities outside of Show Low, Arizona. Offering resort-like qualities, the greatest facilities help achieve a physical, mental and emotional restoration. However, those looking for outpatient therapy may find a program near your residence is an easier decision to make.
Co-occurring disorders refers to a person who is simultaneously wrestling with both drug or alcohol abuse problems and behavioral or mental issues. For instance, an addiction to benzodiazepines or marijuana combined with bipolar disorder, compulsive gambling or an internet addiction. For these individuals, a residential treatment center is definitely preferable, incorporating quality inpatient therapies with support group aid, such as one might see in Alcoholics Anonymous. Luxury drug rehabs in Show Low, Arizona will provide the latest treatment with upscale amenities for anyone requiring the very best substance treatment, just as Show Low alcohol rehab centers will help those battling alcohol addiction to return to sober living.
Note About Insurance for Addiction Treatment: Managed Health Network, Texas Children's Health Plan and First Care usually offer at least some coverage for your addiction treatment, and you can find out more about your own provider's policy or benefit status here.

Technology Did You Know ? This Robot Can See Into Its Own Future Developed
This Robot Can See Into Its Own Future Developed
If you remember then recently, we reported that the day has come when machines make other machines. And today we will present another extraordinary news which will blow your mind, as we are talking about a robot that can see into its own future developed.
Recently, we reported that the day has come when machines make other machines. To be more concrete, it is the beginning of an era in which artificial intelligence systems can build other systems of artificial intelligence. An advance that has made the tech giant Google's AutoML project a reality by designing a computer vision system that far exceeds the most cutting-edge models.
It was in May of this same year when the tech giant Google's Brain researchers announced the creation of this initiative, an automatic learning algorithm that learns to build other machine learning algorithms. The intention was to see what an artificial intelligence was capable of, creating another artificial intelligence without human intervention, with the ultimate aim of achieving greater deployment of these technologies.
There are few humans capable of developing them, they are highly coveted and similar projects would help bring artificial intelligence to many other fields and companies, much more quickly. Otherwise, more slowness would imply a great risk for the AI itself, according to experts like Dave Heiner, the tech giant Microsoft's advisor. Part of its success implies that the implementation is broad.
If robots now want to have babies it was only a matter of time before they could develop an awareness that went beyond simply performing the task for which they were programmed. And one of the first examples of this evolution could be Vestri.
This robotic arm, developed by a group of engineers from the University of California at Berkeley, comes with the ability to "imagine", or project the future of their own actions, or the consequences of their actions.
With the use of this awareness, which allows it to preview the immediate future when performing its functions, Vestri is able to deduce what order of actions its cameras will record before making a specific sequence of movements, to determine how to manipulate objects without failures.
Sergey Levine, assistant professor in Berkeley's Department of Electrical Engineering and Computer Sciences, whose lab developed the technology said that "In the same way that we can imagine how our actions will move the objects in our environment, this method can enable a robot to visualize how different behaviors will affect the world around it. This can enable intelligent planning of highly flexible skills in complex real-world situations."
The demonstration of this can be appreciated in the video above, where Vestri's arm is able to move different items on a test table without colliding with obstacles. Each of these movements was "imagined" by the robot before making them and achieved a precision range close to 90%.
This technology makes it possible for Vestri not to require human intervention to learn to perform simple tasks on its own. Although the initial learning process of the robot was slow and complicated.
Video prediction, the basis of Vestri's "imagination", is a field with a lot of potentials in which the University will continue investigating its scope.

Former Houston GLBT Political Caucus President to lead Harris County Democratic Party
This post originally appeared on Houstini.com on December 22, 2011
Former Houston GLBT Political Caucus president and longtime Democratic party activist Lane Lewis was elected to serve as the Harris County Democratic Party interim chair by the County Executive Committee on Tuesday, December 20. Lewis will serve the remainder of outgoing chairman Gerry Birnburg term, which expires in April. Birnburg announced earlier this year that he would step down after the November general elections.Lewis has also completed his filing as a candidate for HCDP chair on the April 2012 primary ballot.
Lewis previously served as president of the Houston GLBT Political Caucus in 1997. He has a long history of advocacy on LGBT issues.
"Words cannot express the profound sense of responsibility I feel right now," said Lewis moments after his election as HCDP Chair. "I am grateful so many fellow Democrats have entrusted me to lead during such a pivotal time. We have much work to do over the next several months to get our county and our candidates ready for the November 2012 election. This enormous task will take the work of current elected officials, precinct chairs and activists working in unison. My job will be to foster a new vision for our party and work to keep us all focused on our common goal."
During Lewis' acceptance speech, he spoke briefly about the direction and his vision for the party.
"A unified effort from every Democrat is the key to winning elections," Lewis said. "It's plain and simple. The middle class is under attack; the work we do in 2012 will be key to protecting the future and the promise that the American Dream provides."
Lane Lewis was elected by an overwhelming majority. He will begin operating the HCDP immediately.

The number of UK students who took up a place at university this autumn rose 6% on the previous year, figures show.
Statistics from the admissions service, Ucas, show a total of 477,277 students started degree courses in the UK in 2009, compared with 451,871 in 2008.
The rise, partly due to the recession, was expected and the government had announced in July that 10,000 extra places would be made available.
But with applications at record levels, many students have been disappointed.
Applications this year from UK students to the UK's universities were up on last year by 50,935 - about 10% - so the proportion of applicants failing to get a place has risen.
While the Ucas statistics do not specifically indicate how many UK applicants were disappointed, they show 156,315 applicants either withdrew their application or were unsuccessful in finding a university place.
In 2008, 130,786 applications were in this category - 25,529 fewer than this year.
There was also a rise in the number of students getting places going through clearing.
The figures also highlight the possibility that universities in England could be fined for recruiting too many students.
Earlier this year, Westminster put a 10,000 cap on the expansion of university places for this autumn because of budget restraints.
It later increased funding to cover 13,000 extra places for UK and European Union full-time undergraduates, as the number of applicants surged.
However, 372,546 UK and EU applicants won places at English institutions this autumn - 17,943 more than in 2008.
This would suggest that universities have accepted nearly 5,000 too many students.
The government had previously warned that universities that over-recruited would face penalties.
But the Department for Business, Innovation and Skills said it was too early to speculate on over-recruitment and that ministers would wait for further statistics due out in December.
Acting chief executive of Ucas, Virginia Isaac, said this year had been "unprecedented".
"Significantly increased applications and far more students being accepted at a university or college than ever before.
"In particular we have seen a notable increase - of 10.1% - in acceptances of students aged 25 and over."
The Ucas figures also showed 384 students, who got better results than expected, used the new adjustment scheme to find a place at an alternative university.
Ms Isaac said: "While only a small number of applicants utilised the service, it gave students, particularly those with more vocational qualifications, the chance to review their options within a secure framework."
Higher education secretary David Lammy said: "Clearing has been a great success, with early predictions about the lack of places available proving premature, with over 47,000 people finding a place through this service.
"This year, more students than ever before will take advantage of the record number of funded places on offer."
But shadow secretary of state for universities and skills David Willetts said: "These figures confirm ministers have completely messed up this year's university entrance process.
"There was an entirely predictable increase in demand for university this year and the government failed to plan for it.
"The rise in the number of disappointed applicants comes despite over-recruitment by universities, which could lead to fines.
"Ministers have a 50% target for young people going to university and they now look set to penalise universities for meeting it."
Chief executive of the university think-tank million+, Pam Tatlow, said: "If universities had not been prepared to take an additional 10,000 students for whom the government provided student support but not teaching costs, it is clear that many more applicants would have been disappointed.
"The government and the funding council should now withdraw their threat to fine universities which have over-recruited students in what ahs been a record-breaking year.
"Much more work need to be done to identify the number of students who were could not find a university place on the course of their choice and have deferred their applications until next year."


Choosing a suitable, comfortable, and interesting topic for research is one of the biggest intricacies, a research scholar comes to witness. The topic or area of the research should be detailed, unique and researchable. It is not sensible to choose a topic that has no sources available. You will, thus, be wasting your precious time by choosing one such complex topic. If you want to opt for a research program, you ought to have a clear goal in your mind.
Scan Through Internet – To choose a suitable topic, you can take help from Google. It is the biggest help for those who want to do things on their own. You can search for the scope of research in your subject, and come up with an array of things that have never been researched. Internet will also help you during your research.
Meet your professors – If you have tried a lot, but haven't decided upon a topic for your research, you should pay a visit to your professor. Professors and lecturers always carry a list of topics to suggest their students a topic for their research assignment. If you have a topic in your mind, and you are confused, you can discuss it with them. They will offer valuable suggestions. Else wise, you can request them to suggest you a suitable research topic. They will also be helping and working with your during your research, so, you can speak to them, and get a resolution for your bafflement.
Visit seniors, libraries, and sites – Choosing a wrong and complex research topic would only bring loads of disappointments your way. To choose an appropriate topic for your research, you can think of visiting your seniors and local and collage libraries to dig a little more about your subject.

Comedic Hijinks and Feline Antics Abound in Disney's That Darn Cat!
Posted on October 15, 2018 by Michaela Owens
Hayley Mills and Dean Jones in That Darn Cat!
I have always been a Disney kid. Yet it wasn't until a few years ago that I began watching the studio's live-action fare from the '60s. The movies, I'll admit, aren't always gems — for every Blackbeard's Ghost, there is a The One and Only, Genuine, Original Family Band. My favorite discovery so far, though, has been 1965's That Darn Cat!, a movie that has strangely become part of my Halloween rotation even though it really has no relation to the holiday whatsoever. The cat of the film's title is D.C., a troublemaking Siamese who discovers the hideout of two bank robbers and their hostage, a scared bank teller. When the teller switches out D.C.'s collar for her watch with the word "help" scratched on the back, the cat's owner, Patti, makes the connection and contacts FBI agent Zeke Kelso. With the hope of finding the crooks by following D.C. on his nightly strolls, Agent Kelso gets more than he bargained for thanks to Patti's meddling, intrusive neighbors, and one serious cat allergy.
Mills in That Darn Cat!
Jones and Mills in That Darn Cat!
That Darn Cat! was the last of six films that Disney darling Hayley Mills would make for the studio. Precocious yet never cloying, Mills often played bright, bubbly characters who demonstrated a self-sufficiency and maturity that went well beyond her years. Patti is no exception. As someone who craves excitement and finds adventure in everything, working with the FBI proves more than satisfying for the young woman. Her tenacity and scrappy attitude certainly get her into trouble, but they're also the things that save her (and a few other people) in the end.
Provine, Jones, and Mills in That Darn Cat!
Jones in That Darn Cat!
While That Darn Cat! marked the end of an era for Mills, it was the first Disney film for another of the studio's legends, Dean Jones. It is also, I must admit, the film that made me fall in love with him. A handsome man with an abundance of goofy charm, Jones almost steals the entire movie as Agent Kelso. While it would have been easy to play the character as a dopey authority figure, the actor instead chooses to imbue Kelso with strength and resourcefulness. He isn't a perfect agent, but he also isn't ineffectual or moronic. You feel safe with him, a sentiment that Patti's sister Ingrid (Dorothy Provine) comes to agree with over the course of the film, in spite of her relationship with Gregory, an insufferable mama's boy played to sniveling perfection by Roddy McDowall.
Gorshin, Brand, and Grayson Hall
Demarest and Lanchester
Ed Wynn
As you might have noticed, what continually strikes me about Disney films is the impeccable casting. Brilliant character actors were treasured at the studio and That Darn Cat! is a great example of that. Richard Deacon pops up as an annoyed drive-in theater manager; wily Frank Gorshin is excellent as one of the robbers; Neville Brand adds the danger as Gorshin's intense partner; William Demarest plays the grumpy, hilarious husband to Elsa Lanchester's extremely nosy neighbor. Even perennial Disney favorite Ed Wynn shows up as a frazzled jeweler who reluctantly helps Mills.
Lowell in That Darn Cat!
Mills and Lowell in That Darn Cat!
My favorite supporting role, though, is Tom Lowell's fantastic turn as Patti's boyfriend, Canoe. With a bottomless pit for a stomach and a perpetual tobacco pipe in his hand, Canoe is, well, let's just say he is a good counterpoint to Agent Kelso. He is also a clear stereotype of the 1960s teenager, but Lowell brings a sweetness and warmth to the character that saves Canoe from becoming completely one-note.
In addition to most of the cast, That Darn Cat! had people behind the camera who were also beloved members of the Disney family. The title song, for instance, was written by the Sherman Brothers (and sung by Bobby Darin!), while the direction was provided by Robert Stevenson. By the time of this film, Stevenson was a major asset to the studio. In 1957, after helming such classics as Jane Eyre (1943) and The Las Vegas Story (1952), Stevenson came to the Walt Disney Company and wound up staying for 19 films, including Mary Poppins (for which he was Oscar-nominated), Bedknobs and Broomsticks, The Absent-Minded Professor, the aforementioned Blackbeard's Ghost, and The Love Bug. Although I didn't grow up with many of these films, there is something inherently cozy about them. It might just be that magical Disney atmosphere, but I also think Stevenson's winsome direction is a good reason why these movies are still delightful, regardless of how old the audience is or how many years have gone by since they've been made.
Although I will always have immense love and deep nostalgia for the studio's iconic animated films, That Darn Cat! is proof that Disney's live-action work is nothing to sniff at, either. In the coming October days, as the leaves fall and the air gets crisp, you'll find that putting on this film and cuddling up with some hot cocoa are just what you need to start your autumn right.

Q: gcc start address I am currently trying to compile a mbed project offline using gcc-arm-embedded but I want to change the start address as this program is intended to be used with a bootloader so will eventually have to run from 0x10000. I have exported my project as a GCC-ARM-EMBEDDED and am able to build the project with gcc. However I have no idea how to specify the start adress to 0x10000. I have tried to change the LPC1768.ld script, changing the ORIGIN of the FLASH to 0x10000, but it seems that it is not doing anything.
MEMORY
{
  FLASH (rx) : ORIGIN = 0x00010000, LENGTH = 0x70000
  RAM (rwx) : ORIGIN = 0x100000C8, LENGTH = 0x7F38

  USB_RAM(rwx) : ORIGIN = 0x2007C000, LENGTH = 16K
  ETH_RAM(rwx) : ORIGIN = 0x20080000, LENGTH = 16K
}

Is there an option in the Makefile or somewhere else that will help changing the start address of the program, so it can run correctly when I jump from my bootloader to adress 0x10000 ?
EDIT:
I think I understand what I need to achieve thanks to the couple of responses but for some reasons I can't get it working. Mbed does not export the startup_LPC17xx.s file so I tried to use the one from CMSIS, but no luck with that. I am wondering if I actually need to change the startup code as the process is as follow:

*

*Bootloader runs at 0x0000

*Bootloader will do some checks and eventually will run the user-app
sitting at 0x10000. The bootloader actually moves the vector table
before jumping to 0x10000. This user-app is the one I am trying to
build with gcc and will not be running at power-up, only be running
after the bootloader has started itself. Not sure if that's clear but
I would think that only changing the Linker script would work... but it isn't.

Details of the Linker script where I have changed this section address to 0x10000:

SECTIONS {

.text :
{
    *startup_LPC17xx.o
    KEEP(*(.isr_vector))
    *(.text*)

    KEEP(*(.init))
    KEEP(*(.fini))

    /* .ctors */
    *crtbegin.o(.ctors)
    *crtbegin?.o(.ctors)
    *(EXCLUDE_FILE(*crtend?.o *crtend.o) .ctors)
    *(SORT(.ctors.*))
    *(.ctors)

    /* .dtors */
    *crtbegin.o(.dtors)
    *crtbegin?.o(.dtors)
    *(EXCLUDE_FILE(*crtend?.o *crtend.o) .dtors)
    *(SORT(.dtors.*))
    *(.dtors)

    *(.rodata*)

    KEEP(*(.eh_frame*))
} > FLASH

.ARM.extab : etc..

EDIT2: I have added *startup_LPC17xx.o in my script, this seems to be working fine now :)

A: In the linker file, specify a section that starts at 0x10000.  Then in your crt0 or similar startup code, you need to define your reset entry handler as residing in this section so the linker will put it there.  This could be via a .section or #pragma or similar mechanism.  You can verify by looking at the linker's generated map file to see that it is placing your reset handler at 0x10000.

A:
I have tried to change the LPC1768.ld script, changing the ORIGIN of
  the FLASH to 0x10000, but it seems that it is not doing anything.

Check your Linker settings, whether you use the correct linker script. Changing the ORIGIN and size works here (LPC1768 with arm-none-eabi-gcc). Note that the resulting program will not execute on bare metal anymore, as the vector table will be at the wrong position: Your bootloader must be in place to start it.
Note that your bootloader must not jump to 0x10000 but load the reset vector from the table from 0x10004 into the PC. Bonus points when you load the MSP (Main Stack Pointer)  from 0x10000 just before.

RIYADH, Saudi Arabia and WASHINGTON, Jan. 2, 2020 /PRNewswire/ -- Blackboard, a leading education technology company for teaching, learning and student engagement, announced today that Umm Al-Qura University (UQU) has selected Blackboard's leading learning management system, Blackboard Learn, to replace its legacy system. Umm Al-Qura University is one of the largest public Islamic universities in Saudi Arabia, serving over 100,000 students across 35 colleges.
"We are honored that Umm Al-Qura University decided to switch to Blackboard Learn to deliver a more connected, engaging and integrated learning environment across all of its colleges," said Robert Speed, Vice President of the Middle East and Africa at Blackboard. "Our powerful LMS is more equipped to help the university deliver a superior teaching and learning experience for its faculty and students. We have a strong presence in Saudi Arabia and are committed to working with our partner on the ground to help our clients deliver on their mission."
Blackboard Learn will help the university achieve Saudi Arabia's "Vision 2030" and the National Transformation Program (NTP), which set out an ambitious roadmap for education reform. Some of the key benefits of Learn include a connected experience across devices, ease of content creation and management and a range of digital assessment and social learning tools.
"We felt that our old system left us out of sync with many of our peer institutions across Saudi Arabia and around the world, making it difficult for us to engage in endeavors such as joint training, knowledge transfer and exchange of e-learning resources," said Dr. Ahmed Hameed, Vice-Deanship of E-Learning and Distance Education for Development and Entrepreneurship at Umm Al-Qura University.
"Since switching to Blackboard, we have been able to deliver a more connected and engaging learning environment for our faculty and learners. We have also seen a reduction in costs with absolutely no impact on the quality of education we provide."
The university is also leveraging Blackboard Collaborate, a simple and reliable online collaborative learning environment, SafeAssign, an originality-checker, and on-the-go access to coursework and other educational information through Blackboard's mobile solutions.
To ensure a seamless transition, Blackboard is providing training on efficient content migration to Learn from the university's old system.
Our mission is to partner with the global education community to enable learner and institutional success, leveraging innovative technologies and services. With an unmatched understanding of the world of the learner, the most comprehensive student-success solutions, and the greatest capacity for innovation, Blackboard is education's partner in change.

Weekly Davar: Vayechi 2021

Davar Thought
When Jacob was taken to be buried in Israel, his body was accompanied by a very large retinue of both his family and pretty much every Egyptian dignitary. Large funerals are an interesting concept. But why? The person is gone. Surely, it makes no difference to them what type of send-off they get?
Judaism believes that it does.
The rabbis tell us that eulogies must be said at a funeral. And the purpose of those eulogies is to make people cry.
Now that's an interesting concept, particularly in this country. The aim at most funerals that I seem to go to is for everyone, including the mourners, to 'be strong' and NOT cry. The Jewish concept, however, is very much to cry. And the goal of a eulogy is to help with that. Because crying honours the person who has gone. When people cry, it means they cared about the person; it matters to them that the person is no longer here; they feel a hole in their lives that this person once filled. That honours the person – they made a difference in the world. More meaningfully than even the most eloquent words could express, crying demonstrates clearly that the person made their mark in the world. And public crying is the most powerful demonstration of that – because it says that I have been so touched by this person, they mattered so much to me, their loss is so keenly felt – that my inhibitions break down and I express my vulnerability for all to see.
That's crying and it's a beautiful thing at a funeral and a shiva (Jewish house of mourning). It's natural, normal and deeply respectful to cry for someone we love. It always amazes me that people would want to repress something so touching and so beautiful. Personally, I loved crying for my parents and my wife when they passed – and still do.
But still, why show respect for someone who has gone? It makes no difference to them.
I have two thoughts on this. One works even for an atheist, the other is for someone who believes in God.
Firstly, we cry in respect for the feeling of love that we had for the person. It is not for the person; it is for us. We honour the beautiful and meaningful relationship that we had with this person. We are grateful to life for sharing this special human being with us and we express that feeling of gratitude best through tears. There is an underlying joy in such mourning, but it remains mourning.
But the second point is my main one. It is my firm belief that a soul, whilst departing this realm of existence, does not die. It is still alive in a purely spiritual realm (and you can try to conceive of how that might work as much as you like but you still won't have any more understanding than I have, i.e. none of the details). As such, I believe that a soul is somehow still aware of us, even if we are not aware of it. I don't mean that it looks down on us from on high, or in heaven. I think that is all metaphorical. I think that it retains some sort of spiritual connection with our own spiritual experience. It is something (I don't want to use a particular verb, such as comforting, pleasurable, beneficial….. because that would be presumptuous of me, but fill in your own blank if you like) for that soul to know that we care, that it is beloved and missed. And hence, I believe that crying, or rather the deep and passionate feeling that accompanies it, honours the soul of the person that we have loved in this world and will love, more fully than ever before, once reunited after we have also left this world.
This portion tells the story of Jacob's final blessing to his children, his demise and his burial. In his final moments of prophetic vision, Jacob is able to discern the time of the Messianic Era. He wishes to reveal the details to his children, but is prevented from doing so by God.
Jacob dies and is mummified for the journey to Israel. He is taken to Hebron and buried with full Egyptian honours.
