Functional testing might answer questions like: what temperature chilled water is being provided when the outside air temperature is 30°F, 40°F, etc. The inputs to the controls are overridden or simulated in order to document the system's response.
An energy audit focuses on measures that if implemented, will save energy. Many of these measures involve purchasing and installing new capital equipment, such as new chillers, pumps or boilers. RCx focuses on how the existing equipment is controlled. RCx measures are mostly repairing, recalibrating and reprogramming controls and control devices such as temperature sensors and damper actuators. RCx measures are typically inexpensive to implement and typically offer simple paybacks of two years or less.
An RCx study is typically more expensive than an energy audit, however, when you combine the cost of the RCx study with the cost to implement the measures identified in the report, you will find that RCx is typically less expensive than energy audits, as energy audit measures often have longer paybacks.


How Does Fatigue Affect Your Kicking Performance?
By |2020-10-28T08:58:30-05:00October 28th, 2020|Fatigue, Kicking Performance, Lifestyle, Overuse, Soccer|
Fatigue can be considered as a contributing factor for reduced coordination and response time in soccer athletes (8, 11, 13). Generally, the negative effects of fatigue are shown in athlete's decline in muscle strength ability and shifts in coordination (8, 9, 14). These negative changes can impact an athlete's kicking performance (5) and can be costly to both the individual and their team. Several studies have suggested fatigue negatively impacts kicking ball velocity (3, 4, 8, 15). However, other studies have shown conflicting results. A 2009 study found after a simulated match play intervention, athletes showed no changes in kicking [...]

This study analyzed the interrelationships between family resources, learning attitudes, university admission channels, and learning performance. This study used first-year college students enrolled at the case university as the research sample. This research applied the generalized structural equation model and used family resources as its independent variable and learning attitude, university admission channels, and learning performance as dependent variables. Learning performance was separated into intellectual and service learning performance. The empirical results indicated that students with more family resources were less likely to exhibit high intellect and high service learning performance. In addition, students with more family resources were more likely to enter the university through recommendations and screening. Finally, students with superior learning attitudes were more likely to exhibit high intellect and high service learning performance.

text: The theoretical notion of 'construal' captures the idea that the way in which we describe a scene reflects our conceptualization of it. Relying on the concept of ception - which conjoins conception and perception - we operationalized construal and employed a Visual World Paradigm to establish which aspects of linguistic scene description modulate visual scene perception, thereby affecting event conception. By analysing viewing behaviour after alternating ways of describing location (prepositions), agentivity (active/passive voice) and transfer (NP/PP datives), we found that the linguistic construal of a scene affects its spontaneous visual perception in two ways: either by determining the order in which the components of a scene are accessed or by modulating the distribution of attention over the components, making them more or less salient than they naturally are. We also found evidence for the existence of a cline in the construal effect with stronger expressive differences, such as the prepositional manipulation, inducing more prominent changes in visual perception than the dative manipulation. We discuss the claims language can lay to affecting visual information uptake and hence conceptualization of a static scene in the light of these results.

How to Tell the Age of a Palm Tree
Hunker may earn compensation through affiliate links in this story.
Some trees are carbon-dated to determine their ages. This dating method works well for trees that live in climates without great weather fluctuations. If the carbon in the middle of the tree remains in the same area from early growth to maturity, then this dating method can be valid. However, as points out, trees such as palms "do not have a single definable area of their trunk that dates to the tree's early years."
Ask a park ranger about a palm tree in a national park to learn its history.
The general rule for telling the age of a tree is to count the rings on its trunk. However, this rule doesn't work for the palm tree. Indeed, the lack of easily identifiable markings on its trunk makes the palm a challenging tree to date. The best way to determine a palm tree's age is to investigate its history. The life spans of palms are dependent on the type of palm. For example, green thatch palm's life span is about 150 years while an oil palm's life span is only about 25.
Step 1
Research the history of the palm tree you want to date. This is easier if the palm tree is on a protected site, such as a national park. A park ranger or a horticulturalist on site may be able to help you identify how old the palm tree is.
Step 2
Look up the species of the tree using resources at the library to get a general sense of the lifespan of the palm tree.
Step 3
Determine if the tree has gone through a radiocarbon dating process. A national park service representative might be able to tell you if this information is available. Radiocarbon dating is a scientific process that measures the tree's growth rate by analyzing it with chemicals. This is a contested method--and one that's used sometimes for dating palm trees--because it takes the tree's growth rate over a certain time span and infers this rate for the lifespan of the plant. This method, however, doesn't take into account factors that can inhibit growth at any given time, such as climate or disease.

On average, how many vitamins and nutrients are lost when spinach is cooked? Is it more than 50% or under?
This may surprise you. Spinach's value is enhanced by cooking. Or rather, the carotenoid in it, lutein, is locked in a fiber and released by cooking. This is similar to other carotenoids, lycopene and carotene. We don't know whether there are any vitamins in spinach. Its principal value is in its lutein, an anti-oxidant found in the eye. It is helpful in preventing macular degeneration, which can lead to blindness.

When trying to solve the Schrödinger equation for hydrogen, one usually splits up the wave function into two parts:
$\psi(r,\phi,\theta)= R(r)Y_{l,m}(\phi,\theta)$
I understand that the radial part usually has a singularity for the 1s state at $r=0$ and this is why you remove it by writing:
$R(r) = \frac{U(r)}{r}$
But what is the physical meaning of $R(r=0) = \infty$. Wouldn't this mean that the electron cloud is only at the centre of the atomic nucleolus?
Thanks in advance!

The infinitesimal probability for the electron to be in the volume $dV$ around a point $(r,\theta,\phi)\leftrightarrow (x,y,z)$ is given by $$ dP = dV\cdot |\psi(x,y,z)|^2 = dV\cdot |R(r)|^2\cdot |Y_{lm}(\theta,\phi)|^2 =\dots$$ as you can see if you substitute your Ansatz for the wave function. However, the infinitesimal volume $dV=dx\cdot dy\cdot dz$ may be rewritten in terms of differentials of the spherical coordinates as $$ dV = dr\cdot r^2 \cdot d\Omega = dr\cdot r^2 \cdot \sin\theta\cdot d\theta\cdot d\phi $$ where the small solid angle $d\Omega$ was rewritten in terms of the spherical coordinates. You see that for dimensional reasons (or because the surface of a sphere scales like $r^2$), there is an extra factor of $r^2$ in $dV$ and therefore also in $dP$ which suppresses the probability. There is simply not enough volume for small values of $r$.
So $|R(r)|^2$ may still go like $1/r^2$ for small $r$ and in that case, $dV$ will be proportional to $dr$ times a function that is finite for $r\to 0$. Such $dP$ may be integrated and there's no divergence at all near $r=0$.
That's why one should allow the wave function to go like $1/r$ near $r=0$ which is the true counterpart of one-dimensional wave function's being finite near a point. However, Nature doesn't use this particular loophole because the wave function $\psi$ for small $r$ actually scales like $r^l$ where $l$ is the orbital quantum number and the wave function actually never diverges even though it could.

The physical observable is not the wavefunction, but its integral over a finite area. In spherical coordinates, this is:
$P({\vec x})=\int dr\, d\theta\, d\phi r^{2}\sin\theta \psi^{*}\psi$
This integrand is manifestly finite at $r=0$, even if $R(r)$ has a $\frac{1}{r}$ divergance.

Dear _USER_, you were a minute faster but shorter ;-). I think that $\sin^2\theta$ should be just $\sin\theta$. – Luboš Motl Apr 26 '12 at 16:32
Indeed! I'm so used to writing the metric that I forgot the square root. – Jerry Schirmer Apr 26 '12 at 17:16

For a hydrogen-like atom in 3 spatial dimensions, the rewriting of the radial part
is not performed to keep the $u(r)$ part regular, as OP suggests, but usually because the 3D radial equation in terms of the $u$ function has the same form as a 1D Schrödinger equation.
Imagine that the radial wave function goes as a power
$$R(r) ~\sim ~ r^{p} \qquad {\rm for} \qquad r~\to~ 0, \qquad p~\in~\mathbb{R}.$$
On general grounds, one can impose the following list of consistency conditions, listed with the weakest condition first and the strongest condition last.
 1. Normalizability of the wave function $$\infty~>~\langle\psi|\psi\rangle~=~\int d^3r~|\psi(\vec{r})|^2 ~\propto~ \int_0^{\infty} r^{2}dr~|R(r)|^2.$$ Integrability at $r=0$ yields that the power $p>-\frac{3}{2}$. In other words, this normalizability condition does not by itself imply that $R(r)$ or $u(r)$ should be regular at $r=0$, which is also the conclusion of many of the other answers.
 2. The expectation value of the potential energy $V$ should be bounded from below, $$-\infty~<~\langle\psi| V|\psi\rangle~=~\int d^3r~V(r)|\psi(\vec{r})|^2~\propto~-\int_0^{\infty} rdr~|R(r)|^2. $$ Integrability at $r=0$ yields that the power $p>-1$. In other words, $u(r)$ should be regular for $r\to 0$.
 3. The kinetic energy operator (or equivalently, the Laplacian $\Delta$) should behave self-adjointly for two wave functions $\psi_1(\vec{r})$ and $\psi_2(\vec{r})$, $$\langle\psi_1| \Delta\psi_2\rangle~=~-\langle\vec{\nabla}\psi_1| \cdot\vec{\nabla}\psi_2\rangle,$$ without picking up pathological contributions at $r=0$. A detailed analysis shows that the powers of the radial parts of $\psi_1(\vec{r})$ and $\psi_2(\vec{r})$ should satisfy $p>-\frac{1}{2}$.
In comparison, the actual bound state solutions have non-negative $p=\ell\in \mathbb{N}_0$, and therefore satisfy these three conditions.

In addition to the simply geometric constraints that Jerry and Lubos talk about, the derivation used to illustrate the problem almost always assumes that the proton is a point particle which is a pretty good approximation but not strictly true. Working the problem again with a realistic proton charge density function (roughly constant inside a radius of about 1 fm) would be another way to remove the singularity.
Mind you, you this argument does not hold true for the positronium so you still need the geometric constraint.

Re:positronium: wouldn't sub-Compton-wavelength renormalization of the Coulomb law soften the singularity? – Slaviks Apr 26 '12 at 19:28
_USER_: I'm a little on thin ice here, but I think that renormalization does solve the problem, but that's in the context of QFT, while this question seem to be phrased in the language of introductory QM. – dmckee Apr 26 '12 at 19:53
Sure, I was just entertaining the concept :) There is no singularity in the w.f., worrying in about the radial part is just staring at a singularity if the coordinate system, imho. – Slaviks Apr 26 '12 at 19:56
For Hydrogen, $R(r)$ does not diverge, as $U(r)$ vanishes as fast as (or faster than) $r$ as $r\rightarrow 0$. In fact, it's only for the $s$ orbitals that the wavefunction is non zero at $r=0$. But as pointed out before, a non-zero radial wavefunction does not mean a non-zero probability of finding the electron at the center.

Abstract
In this correspondence, the performance and complexity of channel-optimized vector quantizers are studied for the Gauss- Markov source. Some interesting observations on the geometric structure of these quantizers are made which have an important implication on the encoding complexity. For the squared-error distortion measure, it is shown that while the optimum partition is not described by the nearest-neighbor rule, an operation equivalent to a Euclidean distance measurement with respect to an appropriately defined set of points (used to identify the encoding regions) can be used to perform the encoding. This implies that the encoding complexity is proportional to the number of encoding regions. It is then demonstrated that for very noisy channels and a heavily correlated source, when the codebook size is large the number of encoding regions is considerably smaller than the codebook size - implying a reduction in encoding complexity.

Red nail polish has a timeless allure that can be traced back to the ancient world, where it was used as a symbol of power and prestige.
In Ancient Egypt, red nails were a bold fashion statement flaunted by the pharaohs to display their wealth and status. Similarly, in China, red nail polish was reserved exclusively for the elite and represented dominance and affluence.
The color red is often associated with passion, love, and energy, as well as peril, fury, and caution. It can also be linked to good fortune and luck in some cultures or embodied as wickedness or allure in others. Wearing a bold red nail polish can convey self-assurance, fearlessness, and a desire for the spotlight, as well as confidence and boldness.
What does red nail polish mean TikTok?
Red nail polish has taken the world of TikTok by storm with the "red nail theory"! TikTok creator Robyn Delmonte, known as @GirlBossTown, coined the term, which suggests that wearing red nail polish makes you more attractive to potential suitors. While it lacks scientific evidence, this theory has sparked a frenzy on social media, with users eagerly experimenting with different shades of red to test its validity.
Red is considered a bold and confident color that commands attention, and the "red nail theory" is all about harnessing that energy to stand out from the crowd. Despite the lack of concrete evidence, it's fascinating to see how this trend has captured the attention of millions of TikTok users and has become a hot topic of conversation on various social media platforms.
So why not try it out and see for yourself if red nail polish is the secret to grabbing attention and boosting your confidence!
What Does Red Nail Polish Say About You?
Oh, the allure of red nail polish! It's no secret that the color red is associated with passion, love, and energy. But did you know that wearing red nail polish can also reveal a lot about your personality? Individuals who opt for red nail polish are often perceived as confident, bold, and assertive. These traits are often associated with individuals who are go-getters and not afraid to take charge.
Moreover, individuals who wear red nail polish may also be perceived as extroverted, outgoing, and sociable. They are the life of the party, radiating a sense of energy that's hard to ignore. If you're someone who wants to stand out from the crowd, rocking a bold red nail polish may just be the way to go!
On the flip side, some people may perceive individuals wearing red nail polish as attention-seeking or trying too hard to be noticed. However, this largely depends on the context in which the red nail polish is being worn. Ultimately, the perception of individuals wearing red nail polish can vary depending on personal beliefs and cultural norms. Nonetheless, there's no denying that wearing red nail polish can make a bold statement about your personality and sense of style.
What Does Red Nail Polish Mean to Guys?
When it comes to red nail polish and what it means to guys, the perception is overwhelmingly positive. Men tend to view women who wear red nail polish as confident, bold, and full of personality. This classic color exudes a sense of power and self-assurance that can instantly catch a guy's attention. In fact, a study conducted by the cosmetics brand Sally Hansen found that red was the most attractive nail color to men out of all the other shades.
The impact of red nail polish on attraction and confidence cannot be overstated. A bold red hue on your nails can boost your confidence and make you feel more alluring and captivating. It can even make you more approachable to potential suitors. Not only that, but red nail polish has been known to give a polished and sophisticated look that can leave a lasting impression on those around you.
Is Red Nail Polish Considered Trashy?
Red nail polish has long been subjected to unwarranted criticism and stigma, often being labelled as "trashy" or "cheap." However, it's time to debunk this stereotype and acknowledge the beauty and power of this classic hue. Red nail polish has a timeless allure and is a staple in any nail polish collection.
The notion that red nail polish is "trashy" is a baseless social stigma that has unfairly been placed on women who choose to wear it. This stereotype is rooted in outdated beliefs that associate the colour red with sexual promiscuity or low-class behaviour. However, this perception couldn't be further from the truth.
In reality, red nail polish is a bold and confident choice that has been embraced by fashion icons and celebrities alike. It exudes a sense of strength, power, and sex appeal. From Marilyn Monroe to Taylor Swift, countless powerful and successful women have rocked red nails, breaking down the stereotype that it's only for those who lack taste or class.
At the end of the day, the choice to wear red nail polish is a matter of personal preference and style. It's time to ditch the unfounded stigma and embrace the beauty and confidence that comes with rocking a bold red shade.
Is Red Nail Polish Right for Me?
Well, fear not, as we've got you covered! There are several factors to consider before making the leap into the world of red nails. Firstly, it's important to assess your personal style and comfort level with bold, attention-grabbing colors. Red nail polish is a classic and timeless choice that can elevate any outfit, but it may not be for everyone.
Another consideration is skin tone, as certain shades of red may complement different complexions more effectively than others. For example, individuals with fair skin may prefer cooler-toned reds, while those with darker skin may find warmer-toned reds to be more flattering. Additionally, it's important to think about the occasion and environment in which you'll be wearing the nail polish. A bright red hue may be too bold for a conservative workplace, but perfect for a night out on the town.
If you're not quite ready to take the plunge into the world of red nail polish, there are alternative options to consider. A sheer red tint can provide a subtle pop of color without being too overwhelming, while a darker burgundy shade can offer a more muted take on the classic red nail. Ultimately, the decision to wear red nail polish comes down to personal preference and comfort, so don't be afraid to experiment and find what works best for you!

The Geostationary Earth Radiation Budget (GERB) experiment is a broadband satellite radiometer instrument program intended to resolve remaining uncertainties surrounding the effect of cloud radiative feedback on future climate change. By use of a custom-designed diffraction-aberration telescope model, the GERB detector spatial response is recovered by deconvolution applied to the ground calibration point-spread function (PSF) measurements. An ensemble of randomly generated white-noise test scenes, combined with the measured telescope transfer function results in the effect of noise on the deconvolution being significantly reduced. With the recovered detector response as a base, the same model is applied in construction of the predicted in-flight field-of-view response of each GERB pixel to both short- and long-wave Earth radiance. The results of this study can now be used to simulate and investigate the instantaneous sampling errors incurred by GERB. Also, the developed deconvolution method may be highly applicable in enhancing images or PSF data for any telescope system for which a wave-front error measurement is available.

Parachute Jumper Gives Imitation of a Flying Squirrel (Sep, 1930)
Parachute Jumper Gives Imitation of a Flying Squirrel
IN a startling imitation of a flying squirrel, Rex G. Finney, parachute juniper of the Curtiss-Wright Flying Service, demonstrated his stunt of becoming a human glider before the public recently with great success.
A triangular piece of sail cloth sewn between the legs of his flying suit acts upon the air in the same manner as the membranes of the flying squirrel, enabling him to perform thrilling glides and stalls while in the air.
As he jumps from the plane, Finney stretches his legs apart, and the wind, acting upon the web between his outstretched legs in much the same manner as it acts. upon the elevators of a plane, enables him to glide a steep angle. By doubling his knees he is thrown into a climbing stall.

text: This study examines the evolution of exchange rate pass-through (ERPT) into import, producer, and consumer prices in Peru from 1995Q2 to 2022Q4 using time-varying parameter and stochastic volatility VAR models. Findings reveal a resurgence of ERPTs into import and producer prices since 2009, particularly during the period of a strong US dollar following the 2013 taper tantrum and from 2020 to 2022. Increased uncertainty surrounding the exchange rate and future macroeconomic policies, triggered by the political uncertainty following the 2021 general elections, may have contributed to this trend. Short-term ERPT exceeds long-term ERPT, which might reflect prevalent price dollarization in Peru's import and producer prices. Consumer ERPT remained stable at around 10% until 2009, then increased to 15%, indicating lower levels of price dollarization. This paper sheds light on ERPT dynamics in Peru, carrying implications for policymakers in emerging economies.

Python pyperclip
What is Python pyperclip?
Python pyperclip is a Python Library that can manipulate the clipboard by enabling us to use the copy and paste functions.
Installation
Windows users do not have to download any dependencies, however Linux users need to first install the xclip or xsel library from the command prompt first.
Linux
sudo apt-get install xclip
pip install pyperclip
Windows
pip install pyperclip
Example Usage
pyperclip.copy() is used to copy text into the clipboard.
pyperclip.paste() will return the contents of the clipboard.
The below code will first copy the string "Hello World" to the clipboard. Once the pyperclip.paste() function is called, the same string will be printed out.
import pyperclip
pyperclip.copy('Hello world')
print(pyperclip.paste())
Keep in mind that this library functions like a regular clipboard. If you consecutively copy two values into the clipboard, the first will be over-written. A clipboard can only have one value at a time.
import pyperclip
pyperclip.copy("Hello World")
pyperclip.copy("Goodbye World")
x = pyperclip.paste()
print(x)
Output
Goodbye World

Channel Power (Sp): If the owner is 15th level or higher, he can manifest powers through the psicrystal to a distance of up to 1 mile. The psicrystal is treated as the power's originator, and all ranges are calculated from its location.
When channeling a power through his psicrystal, the owner manifests the power by paying its power point cost. He is still subject to attacks of opportunity and other hazards of manifesting a power, if applicable (for instance, he becomes visible when manifesting an offensive power if invisible, as does the psicrystal).
Psicrystal Personality (Ex): Each psicrystal has a distinct personality, chosen by its owner at the time of its creation from among those given on the following table. At 1st level, its owner typically gets a feel for a psicrystal's personality only through occasional impulses, but as the owner increases in level the psicrystal's personality becomes more pronounced. At higher levels, it is not uncommon for a psicrystal to constantly ply its owner with observations and advice, often severely slanted toward the psicrystal's particular worldview. The owner always sees a bit of himself in his psicrystal, even if magnified and therefore distorted.

In the current era of sustainable transportation, Electric Vehicles (EVs) have emerged as a promising solution to combat environmental concerns and reduce our dependency on fossil fuels.
As the EV market expands, various components of these vehicles are being fine-tuned and optimized for better performance, and one crucial element is often overlooked: the tyres designed specifically for Electric Vehicles.
Understanding Electric Vehicles
Electric Vehicles operate on rechargeable batteries, using electric motors for propulsion. Unlike internal combustion engine vehicles, EVs generate instant torque and have a different weight distribution due to battery placement. These unique characteristics demand specialized engineering, including the tyres they ride on.
The Role of EV Tyres
EV-specific tyres are engineered to meet the distinctive demands of electric vehicles, considering factors such as weight distribution, torque delivery, and energy efficiency. They are designed to maximize the benefits of electric propulsion systems, offering improved range, handling, and efficiency while maintaining safety standards.
Key Features of EV Tyres
 1. Low Rolling Resistance
 EVs aim for maximum energy efficiency, and specialized tyres with low rolling resistance contribute significantly to achieving this goal. Reduced resistance means less energy is required to move the vehicle, thereby extending the range per charge.
 2. Enhanced Durability
 Electric Vehicles are often heavier due to the battery weight, which can impact tyre wear. EV-specific tyres are crafted to endure higher weight capacities, ensuring longer tread life and reducing the frequency of replacements.
 3. Optimized Grip and Handling
 The instant torque delivered by electric motors demands superior traction and grip. EV tyres are engineered to provide better traction and handling, enhancing the driving experience and safety, especially in various weather conditions.
 4. Noise Reduction
 Electric Vehicles are notably quieter than traditional vehicles. EV-specific tyres are designed to further reduce road noise, contributing to a quieter and more comfortable driving experience.
 5. Maintenance and Considerations
 As with any vehicle component, regular maintenance is crucial. Maintaining the correct tyre pressure and scheduling routine inspections is imperative for optimal EV performance and safety. Additionally, considering the unique demands of electric propulsion, regular alignment checks are recommended to ensure even tyre wear.
The Future of EV Tyres
With the ever-evolving EV landscape, tyre manufacturers continue to invest in research and development to further enhance EV-specific tyres. Innovations such as novel rubber compounds, advanced tread designs, and smart tyre technologies are being explored to meet the evolving needs of electric vehicles.
Conclusion
As the EV market grows, tyre manufacturers continue to innovate and tailor their products to meet the unique requirements of electric propulsion systems. Embracing these specialized tyres ensures not only better efficiency but also a safer and more enjoyable driving experience for all electric vehicle owners.

I would like to know what type of machine learning to use for recognizing events in a set of data. (or at least be pointed in the right direction so I can do my own research on the topic.)
I'm trying to identify M&M color using an RGB sensor. Here is an example of some data I collected. I want to train a neural network by saying "this is what it looks like when a blue M&M passes by the sensor... And a yellow..." So it then can tell me when and what color M&M has passed by.
My type of problem is similar to this. In this case, they record accelerometer data and use it to identify the exercise someone was doing.
How can you teach an ANN to do this? And how do you teach it what an "event" looks like?
** P.S. I'm new to this forum so any modifications to my question to make it more relevant and understandable are welcome.
You will need your data to look something like this:
Blue Red Green Label
20 12 13 _
18 11 13 _
18 12 13 _
19 13 14 _
24 12 13 _
28 14 19 B
30 19 21 B
29 18 20 B
25 14 16 B
21 12 13 _
19 11 12 _
18 11 12 _
That is, every point in the data will need to be annotated with a label: _ for nothing, B for blue, Y for yellow.
A sequence labeling model can be trained to predict the label for each point in the input sequence. Note that it's common to use a "Begin Inside Outside" (BIO) scheme to help the model understand when an "event" starts and ends:
Blue Red Green Label
20 12 13 Outside
18 11 13 Outside
18 12 13 Outside
19 13 14 Outside
24 12 13 Outside
28 14 19 B_Begin
30 19 21 B_Inside
29 18 20 B_Inside
25 14 16 B_Inside
21 12 13 Outside
19 11 12 Outside
18 11 12 Outside
(there are also variants of this scheme)
As far as I know Conditional Random Fields would be the traditional approach for this kind of task, but there might more recent NN approaches that I'm not aware of.

Relationship of skin surface area to body mass in the immature rat: a reexamination
D. E. Spiers, V. Candas
Skin surface area (Ab) was measured in the rat beginning at birth mass and extending over a range of body mass (m) from 5.0 to 49.3 g. Area of each animal was determined using an elastic impression material. The best-fit relationship between Ab and m over the entire range of mass was Ab = 6.88m0.736. Results suggest, however, that the standard mass exponent of two-thirds, for estimating Ab of adult animals, could also be used for immature animals weighing 14 g or more. In rats weighing less than 14 g, the mass coefficient of the Meeh-Rubner equation varies with m, indicating that the two-thirds exponent is inappropriate for use with very young animals.

Design of a Robust Priming Controller for SMA Actuators
Song, Zihao Hunter
MetadataShow full item record
Shape Memory Alloys (SMAs) have been demonstrated to be effective actuator elements in a wide range of applications, such as robotics, medicine, aerospace and automotive. Enabled by the unique thermo-mechanical properties of SMAs, these actuators offer the advantages of light weight, high power-to-weight ratio and a simple actuation mechanism compared to traditional actuator types. At the same time, the widespread adoption of the SMA actuator remains elusive as its low power efficiency and complex hysteretic behaviour often render it an impractical means of actuation. These actuators also exhibit a slow response speed and their response is highly sensitive to changes in the external environment, namely ambient temperature and mechanical stress, thus complicating their control. Position, force or temperature sensors may be used to facilitate feedback control, but at the cost of increasing the overall size and complexity of the system. The difficulties caused by the hysteretic behaviour can be largely avoided when SMA wires are used as on-off actuators, making SMAs well suited for such applications. However, they may still be subject to a wide range of dynamic operating conditions that would impact their actuation time, and achieving a consistent actuation time is often highly desirable. This thesis presents the synthesis of a nitinol SMA actuator control system which uses electrical resistance feedback to enable a fast response speed and robustness to disturbances in the external environment. A study of the resistance behaviour of SMAs is discussed first. The design of an adaptive controller and the experimental evaluation of its performance are described in detail next. The objective of the SMA actuator control system is to achieve a consistent and fast actuation time throughout the range of operating ambient temperature and stress. The control system is implemented experimentally and shown to be quite successful.

text: Chitosan (CHIT) and carbon nanofiber (CNF) modified pencil graphite electrodes (PGEs) were developed for the first time in the present study for enhanced monitoring of DNA hybridization. CHIT-CNF modified PGE, CHIT modified PGE and unmodified PGE were firstly characterized by scanning electrone microscopy (SEM), and the electrochemical behaviour of each electrode was investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The optimization of experimental studies; CNF concentration, or DNA probe concentration was performed by differential pulse voltammetry (DPV) technique. The sequence-selective DNA hybridization related to Hepatitis B virus (HBV) was then performed in the case of hybridization between HBV probe and its target DNA, or different non-complementary DNA sequences (NC1 and NC2), and also the hybridization case in the mixture samples containing both target and NC sequences in the ratio of 1: 1. CHIT-CNF-PGEs presented very effective discrimination of HBV DNA hybridization, which also presented high sensitivity and better reproducibility due to the unique chemical and structural properties of CNF.

Using Fine-Grained Auditing
Purpose
The goal of this tutorial is to show how fine-grained auditing can be used to detect access to a "honey token" in a table .
Time to Complete
Approximately 30 minutes
Topics
This tutorial covers the following topics:
 Overview
 Prerequisites
Setup
 Creating and Applying a VPD Policy
 Testing the Policy Implementation
 Checking the Audit Violations
 Cleanup
 Summary
Viewing Screenshots
 Place the cursor over this icon to load and view all the screenshots for this tutorial. (Caution: This action loads all screenshots simultaneously, so response time may be slow depending on your Internet connection.)
Note: Alternatively, you can place the cursor over each individual icon in the following steps to load and view only the screenshot associated with that step.
Overview
Policies you establish with fine-grained auditing can monitor data access based on content. Using policies, you can specify the columns and conditions that you want audit records for. Conditions can include limiting the audit to specific types of DML statements used in connection with the columns that you specify. You can also provide the name of the routine you want called when an audit event occurs. This routine can notify or alert administrators or handle errors and anomalies.
Scenario
This tutorial shows how fine-grained auditing is used to detect access to a "honey token" in a table. In this tutorial, a VPD policy is created that limits access to rows by credit card vendor. The honey token is a credit card number that is never selected. It fails the usual verifications, and the number cannot be related to any vendor, so authorized access to this row is not possible.
The VPD policy excludes OE, the owner of this table. OE is granted full access, so when OE (or a hacker who obtained this identity) executes
select * from oe.cust_payment_info
the honey token is selected and the FGA policy records this event. In addition, you could invoke an event handler (not included in this tutorial), to send an email to audit_admin about the access to this special row.
This tutorial separates duties between the following users:
HR_sec Creates database users (from a list of employees in the hr.employees table) and database roles.
sec_admin
Creates and applies the VPD and FGA policies according to the company's access control and auditing policies.
audit_admin Queries the audit record in the database ( dba_fga_audit_trail).
Back to Topic List
Prerequisites
Befor you perform this tutorial, you should:
1.
Perform the Installing Oracle Database 10g on Windows tutorial.
2.
Download and unzip the fga.zip file into your working directory (c:\wkdir).
Back to Topic List
Setup
In this section, you update your sqlnet.ora, create an encrypted wallet ( ewallet.p12), open the wallet, and create the master key for TDE. Perform the following steps:
1.
(OPTIONAL: This topic should be performed only if you have not performed this section in a previous lesson) You need to update your sqlnet.ora file to include an entry for ENCRYPTED_WALLET_LOCATION. Open the c:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora file using either Notepad or Wordpad. Add the following entry to the end of the file:

ENCRYPTION_WALLET_LOCATION=

(SOURCE=(METHOD=FILE)(METHOD_DATA=
(DIRECTORY=c:\oracle\product\10.2.0\db_1\)))
Save your changes and close the file.
Note: Any directory can be picked for the encrypted wallet, but the path should not point to the standard obfuscated wallet ( cwallet.sso) created during DB installation.

2.
(OPTIONAL: This topic should be performed only if you have not performed this section in a previous lesson) Next, you need to open the wallet and create the master encryption key. Select Start > Programs > Oracle - OraDb10g_home1 > Application Development > SQL Plus. Enter /nolog for the User Name and click OK. Then enter the following command:

@c:\wkdir\fga00_dbsetup
connect / as sysdba
alter system set key identified by "welcome1";

The above alter command does the following:
 If no encrypted wallet is present in the directory specified, the encrypted wallet is created ( ewallet.p12), the wallet is opened, and the master key for created/recreated.
 If the encrypted wallet is present in the directory specified, the walled is opened, and the master key is created/recreated.
Note: only users with the ' alter system' privilege can create a master key or open the wallet.
The master key should only be created once, unless you want to re-encrypt your data with a new encryption key !!!
For later sessions, you do not want to use the command given above; you need the wallet to be open (it has been closed when you shut down your database), but you don't want to create a new master key. Then the command is:
alter system set wallet open identified by "welcome1";
The master encryption key is necessary because each table has its own encryption key. These column keys are stored in the database. Since the wallet can only store a limited number of keys and is not very scalable, the column keys are encrypted with the master key. This way, you can have as many column keys as needed, with only a small number of master keys stored in the wallet (including retired keys, that you may need one day to decrypt data from an old backup-tape). By default, the command above generates a key using the Advanced Encryption Standard with 192 bits (AES192). 3DES could also be used, or a smaller or bigger number of bits for the AES encryption.

3.
In this tutorial, you create a set of users and roles to demonstrate how FGA works. You create a customer payment information table and populate it with credit card numbers. The credit card number associated with "Honey Token" is impossible, so this row is never selected by authorized users. It is only selected by administrative users who are exempt from access policies or intruders who became administrative 'insiders'. This allows for highly focused auditing on this table. From your SQL*Plus window, execute the following script:

@c:\wkdir\01_fga_poptabl

conn oe/oe

create table cust_payment_info
(first_name varchar2(11),
last_name varchar2(10),
order_number number(5),
credit_card_number varchar2(16) ENCRYPT);
insert into cust_payment_info values
('Jon', 'Oldfield', 10001, '5446959708812985');
insert into cust_payment_info values
('Chris', 'White', 10002, '5122358046082560');
insert into cust_payment_info values

Consumer Behaviour of Purchasing Digital Camera
1.0 Introduction
In order to market the product into the market successfully, marketers need to have some marketing strategy to enter the desired market and make profit. Market segmentation is the process of dividing a market into subsets of consumers with common needs or characteristics (Schiffman et al., 2011). Understanding the market size and segmentation is valuable, but the keys to effective targeting is to know just how valuable specific consumer groups are, and being able to quantify the impact of consumer trends ( Berry, 1999).
The purpose if this paper is to define the market segmentation for digital camera. Especially focus on Nikon digital camera which is the chosen product in
…show more content…
According to the consumer feedback survey conducted by Nikon in 2011, the consumers considered Nikon digital camera as user-friendly, affordable price, well performance and good quality. The significant signal to explain this stage can be affordable price and good quality of the product.
2.1.2. Product benefits
After the product attributes it goes to the second stage which is product benefits. There are two consequences can discussed under the field of product benefits, namely as functional consequences and psychosocial consequences.
The functional consequences is the tangible consequences of the product, it focus more on "what function is perform?'Also, it can be considered as an external influence to the consumer. In this case the consequences may be user-friendly and excellence photographic performance.
The psychosocial consequence is a combination of psychological and social consequences. It emphasized more on 'How I feel?' and 'How people feel about me?'which is more likely to be the internal influences to the consumers. Attraction and communication are significantly elements in this part. For example, Nikon consumer may feel they catch people attention when they are using Nikon digital camera which is the psychological consequence. Also the consumer may feel happy when they are using Nikon digital camera with others and create positiveexperience about the product, this may considered as social consequence.

Observing variable access using dynamic lookup wrapper
Hello,
I want to have an object that observes and records what values get accessed from a stored variable and dynamically lookup the stored variables' values on access (that part works). But if no dynamic lookup (access to a child variable) is given, I want access to the ObservableState struct to return the value itself.
The goal here is to wrap the state as if it is the variable itself, and record the access to its child variables and to the variable itself. This recorded access is later used to determine whether a View-closure should be re-run. Access to the value itself (without dynamic lookup) is necessary because the state can for example be an Int or a struct that is copied and used elsewhere.
Is there a way?
Attempt 1: somehow returning the state itself when no variable is accessed? Found no way.
@dynamicMemberLookup
struct ObservableState<State> {
 fileprivate let _state: CurrentValueRelay<State>
 // ERROR: How do I do this?
 var self: State {
 // When no variable is accessed, return the value of _state.
 _state.value
 }

 // Values of state.
 public subscript<Value>(dynamicMember keyPath: KeyPath<State, Value>) -> Value {
 return self._state.value[keyPath: keyPath]
 }
}
Attempt 2: Property Wrapper does not work because accessing values goes directly over the wrapped value.
@propertyWrapper
@dynamicMemberLookup
public struct AccessObserved<State> {
 let _state: CurrentValueRelay<State>
 let comparisonState: ComparisonState

 public var wrappedValue: State {
 get {
 print("Accessed base .state")
 comparisonState.oneIsInequatable = true
 return _state.value
 }
 }
 // ERROR: Never called, because .dot-access just returns the wrapped values' children instead of going through these.

 public subscript<Value>(dynamicMember keyPath: KeyPath<State, Value>) -> Value {
 comparisonState.oneIsInequatable = true
 return self._state.value[keyPath: keyPath]
 }

 public subscript<Value: Equatable>(dynamicMember keyPath: KeyPath<State, Value>) -> Value {
 let value = self._state.value[keyPath: keyPath]

Context:
Currently, incase any variable in the state changes, the view-closure is re-evaluated. This can be scoped down, but the scoping can be tedious and people forget to scope properly sometimes. Using the detection of access allows checking only the accessed values for comparison, automatically ignoring changes to unused variables.

Urine Off LED Black Light Urine Finder
The Urine-Off Urine Finder Light is custom-engineered to locate those hidden, dried uric salt crystalsinvisible to the naked eye. The crystalline structure of dried urine causes it to fluoresce a dull yellow color under ultraviolet (UV or "black") light. After locating the dried urine, apply a cleaning solution as needed.
 - LED light more effectively fluoresces urine, making invisible deposits easier and faster to detect and treat. This is the ideal tool to locate hard-to-find urine stains that are invisible to the naked eye.
 - Discrete wavelength is engineered to concentrate much of its power within the 380–382.5 nanometer wavelengths to specifically detect urine and other body fluids
 - Professional grade aircraft aluminium construction.
What's the difference between Urine Finder black light and others?
"Black" or ultraviolet (UV) light is a type of light wave within a certain fairly broad frequency range. Within that range, there is a specific light frequency that will cause urine to fluoresce as brightly as possible. Bio-Pro Research Urine Finders are engineered to produce that specific wavelength of UV light, so they simply work better than generic black lights and make the task of locating urine deposits easier.
Any fluorescent "black light" will fluoresce dried urine to some degree – but the brightness will depend on the actual wavelength of the light output, and this varies considerably from light to light. Even among different lights of the same make and model, the manufacturing tolerances of consumer-grade black lights are simply not demanding enough to reliably produce a specific UV light wavelength. These lights are fine for their intended purpose, but for the specific job of detecting dried urine, they are less than ideal (note: incandescent/screw-in household bulbs with "black light" coatings generally will NOT fluoresce urine at all).
Tool measures 6 5/8" long.
Requires (3) AAA batteries – not included

What is your favorite sport? Wait, do I mean your favorite sport to play or your favorite sport to watch? Does it matter? Are your favorite to-watch sport and your favorite to-play sport the same sport or different? How does your list of favorite sports to play associate or correlate with your favorite sports to watch?
In this activity students rank a list of sports in order from favorite to play to least favorite to play. Then they rank the same list of sports from favorite to watch to least favorite to watch. Students take the rank for each sport and plot the points on the grid. One example is pictured below.
This activity targets 8th grade and/or high school to scatter plot standards and can be easily adapted for younger students, say 5th grade, to introduce or practice graphing in one quadrant.

Former HHS Secretary Recommends Medicaid Reforms
Former HHS Secretary Tommy Thompson on Friday plans to release a "white paper" in which he recommends that the responsibility for long-term care of elderly Medicaid beneficiaries shift from joint state and federal funding to the federal government, the Washington Post reports. Thompson, who will speak to the National Governors Association on Saturday in Charleston, S.C., recommends that states focus on acute care for Medicaid beneficiaries younger than 65.
In addition, Thompson recommends that Medicaid begin to use electronic health records and other technologies to improve case management and health information collection. He recommends that Medicaid beneficiaries receive education on health literacy and disease prevention. According to Thompson, the recommendations would result in long-term savings that states could use to provide health insurance for more uninsured residents, in some cases through subsidies for private coverage.
You want to set up almost a competitive environment where the states will strive to improve upon the healthfulness of their populations, and that will result in less costs for the states at the acute level," Thompson said, adding, "And as these people get older and they move over into the federal responsibility, they will be less expensive for the federal side as well, because you're inheriting a healthier population" (Lee, Washington Post, 8/3).

As it continues to improve its sensor technology to help its vehicle understand its surroundings and respond quickly and safely to unfolding events, it's also been considering how to deal with unavoidable collisions, whether it's with a "soft" human that could easily sustain an injury, or a harder object like another vehicle. A patent recently awarded to Waymo offers some insight into how the company is approaching the issue. In Waymo's own words: "The vehicle may contain tension members that are arranged so that a change in tension across one or more of the tension members will alter the rigidity of the vehicle's surface. The vehicle may identify and respond to a potential collision by altering the tension that is applied to one or more tension members, thereby altering the rigidity of the vehicle's surface."

Traction robot conveying technology is efficient in horizontal well logging. Auto-centralizer is an assistant support to bear the weight of robot and center the robot in casing while logging. The mechanical model for an auto-centralizer with four pair of bias arms was built based on spring-lever mechanism. ADAMS (Automatic Dynamic Analysis of Mechanical Systems) was applied to analyze the sensitiveness coefficient of structural parameters and spring force, thus optimizing the structural parameters. Consequently, a simulation model was built based on the optimization result, and a simulation study was carried out on the mechanical properties and dynamic performance with the ADAMS mechanics system modeling and simulation module. The results implied that the original structure had a disadvantage while traversing obstacles. Further studies indicated that the coupling between the pair arms adopted hinge joint, which couldn't form a closed triangle of force while traversing obstacles. We have employed an improved structure by adding a connecting lever to eliminate the constraint between the arms. Contrast experiments show that the new structure avoids bearing the load with one side and has less shock while traversing obstacles, thus improving smoothness of movement for the traction robot. © 2010 Research Institute of Petroleum Exploration & Development, PetroChina.

Synthesis of speech and song: commonalities and differences, style versus individuality
Takeshi Saitou, Japan's National Institute of Advanced Industrial Science and Technology (AIST) Hideki Kawahara, Wakayama University
This seminar will feature two distinguished guests from Japan. Dr. Takeshi Saitou of Japan's National Institute of Advanced Industrial Science and Technology (AIST) will present his method for Morphing audio from speech to song, by which a text recorded by a speaker can be reprocessed into a song, preserving phonetic realism, with melody and other attributes of singing added.
To follow, Professor Hideki Kawahara of Wakayama University, inventor of the well-known STRAIGHT algorithm for voice synthesis, will present a project on speech analysis and modification method based on an elaborated VOCODER and a morphing procedure. He will then moderate an open discussion of possible ways of handling singing/speaking style and individuality separately.

Remote Sensing Collections is a data management activity, developed to improve access to satellite remote sensed marine products and as such does not directly deploy instruments. The primary focus of Remote Sensing Collections is sea surface temperature and ocean colour products, but also assists the other Satellite Remote Sensing (LINK) Sub-Facilities, facilitating data availability and facilitate user access where needs can't be met routinely via the ADON portal.
The baseline datasets created and managed by Remote Sensing Collections are formatted and organised for efficient storage and access using community-adopted standards such as netCDF. A core activity of Remote Sensing Collections are:
- Provide documentation and tools
- Assist with managing and maintaining core Satellite Remote Sensing datasets
- Enable specialised tools to access datasets that are not readily delivered through the AODN data portal
- Re-organise data to improve useability in response to community demand
In addition to the data sets produced from IMOS Facilities, there are also many global datasets available. Remote Sensing Collections seeks (through community consultation) to identify datasets of value and, where appropriate, play a role in maintaining local archives.

text: The tsB5 isolate of herpes simplex virus type I (HSV-1) enters host cells more rapidly than does KOS, an independent isolate of HSV-1, and this rate-of-entry determinant is located between prototypic map coordinates 0.350 and 0.360 (1). The nucleotide sequence of strain tsB5 has now been determined between prototypic map coordinates 0.347 and 0.360. Comparison of the tsB5 sequence to the homologous KOS sequence revealed that the rate-of-entry difference between these two HSV-1 strains may be due to the single amino acid difference observed within these sequences (0.350 to 0.360). A cell fusion determinant in tsB5 is located between coordinates 0.345 and 0.355 and to the left of the rate-of-entry determinant (1). Nucleotide sequence analysis revealed a second amino acid difference between tsB5 and KOS at coordinate 0.349. The cell fusion determinant was tentatively assigned to this location.


to be transported out of a link queue.
 - Ready A ready queue is needed to allow messages to be transported out of a system queue. When link queues are ready, they can have a connection allocated to them.
 - Retry A connection attempt has failed and the server is waiting to retry.
 - Scheduled The server is waiting for a scheduled connection time.
 - Remote The server is waiting for a remote dequeue command (TURN/ETRN).
 - Frozen The queue is frozen, and none of its messages can be processed for routing. Messages can enter the queue, however, as long as the Exchange routing categorizer is running. You must unfreeze the queue to resume normal queue operations.
Administrators can choose to enable or disable connections to queues. If connections are disabled, the queue is unable to route and deliver messages.
You can change the queue state to Active by using the FORCE CONNECTION command. When you do this, Exchange Server should immediately enable a connection for the queue, which will allow messages to be routed and delivered from it. You can force a connection to change the Retry or Scheduled state as well.
Other summary information that you may find useful in troubleshooting includes:
 - Time Of Submission Of Oldest Msg Tells you when the oldest message was sent by a client. Any time the oldest message has been in the queue for several days, you have a problem with message delivery. Either Exchange Server is having a problem routing that specific message, or a deeper routing problem may be affecting the organization.
 - Total # Of Msgs Tells you the total number of messages waiting in the queue. If you see a large number of messages waiting in the queue, you may have a connectivity or routing problem.
 - Total Msg Size (KB) Tells you the total size of all messages in the queue. Large messages can take a long time to deliver, and, as a result, they may slow down message delivery.
 - Time Of Next Connection Retry When the connection state is Retry, this column tells you when another connection attempt will be made. You can use Force Connection to attempt a connection immediately.
Viewing Message Details
Anytime a message is displayed in a queue, you can double-click it to view message details. The details provide additional information that identifies the message, including a message ID that you can use with message tracking.
Enabling and Disabling Connections to Queues
The only way to enable and disable connections to queues is on a global basis, which means that you enable or disable all queues for a given SMTP virtual server, MTA object, or connector. Enabling queues makes the queues available for routing and delivery. Disabling queues makes the queues unavailable for routing and delivery.
To enable or disable connections to queues, follow these steps:
 1. Start System Manager.
 2. Navigate to the Queues node for the SMTP virtual server, MTA object, or connector you want to manage.
 3. To enable connections to all queues, right-click the Queues node, and then select Enable All Connections.
 4. To disable connections to all queues, right-click the Queues node, and then select Disable All Connections.
Forcing Connections to Queues
In most cases you can change the queue state to Active by forcing a connection. Simply right-click the queue, and then select Force Connection. When you do this, Exchange Server should immediately enable connections to the queue, and this should allow messages to be routed and delivered from it.
Freezing and Unfreezing Queues
When you freeze a queue, all message transfer out of that queue stops. This means that messages can continue to enter the queue but no messages will leave it. To restore normal operations, you must unfreeze the queue.
You freeze and then unfreeze a queue by completing the following steps:
 1. Start System Manager, and then navigate to the queue you want to work with.
 2. Enumerate the queue so that you can see the messages it contains.
 3. Right-click the queue, and then select Freeze All Messages.
 4. When you're done troubleshooting, right-click the queue, and then select Unfreeze All Messages.
Another way to freeze messages in a queue is to do so selectively. In this way, you can control the transport of a single message or several messages that may be causing problems on the server. For example, if a large message is delaying the delivery of other messages, you can freeze the message until other messages have left the queue. Afterward, you can unfreeze the message to resume normal delivery.
To freeze and then unfreeze an individual message, complete the following steps:
 1. Start System Manager, and then navigate to the queue you want to work with.
 2. Enumerate messages in the queue.
 3. Right-click the problem message, and then select Freeze.
 4. When you're ready to resume delivery of the message, right-click the problem message, and then select Unfreeze.
Deleting Messages from Queues
You can remove messages from queues in several ways. To delete all messages in a queue, follow these steps:
 1. Start System Manager, and then navigate to the queue you want to work with.
 2. Enumerate the messages in the queue to make sure that you really want to delete all the messages that the queue contains.
 3. Right-click the queue, and then select one of the following options:
 - Delete All Messages (No NDR) Deletes all messages from the queue without sending a nondelivery report to the sender
 - Delete All Messages (Send NDR) Deletes all messages from the queue and notifies the sender with a nondelivery report
 4. When prompted, click Yes to confirm the deletion.
To delete messages selectively, follow these steps:
 1. Start System Manager, and then navigate to the queue you want to work with.
 2. Enumerate messages in the queue.
 3. Right-click the message or messages that you want to delete, and then select one of the following options:
 - Delete Messages (No NDR) Deletes the selected messages from the queue without sending a nondelivery report to the sender.
 - Delete Messages (Send NDR) Deletes the selected messages from the queue and notifies the sender with a nondelivery report.
 4. When prompted, click Yes to confirm the deletion.
Deleting messages from a queue removes them from the messaging system permanently. You can't recover the deleted messages.
