Can Solar Backpacks Get Wet?
Before investing in a good piece of gear like a solar backpack, it makes sense that you want to make sure it will hold up. There are a lot of different rumors, stories, and claims about how solar backpacks handle water. This article is here to answer all of your questions on the topic.
Solar backpacks are water resistant, but not waterproof. The solar panels will not be damaged from water or rain. So it's perfect fine for solar backpacks to get wet, but as with any pack you don't want an exposed electronic charging when the rain is pouring down and you're soaked.

Solar Power Must Be Weather Resistant
Considering that solar power by definition needs to be used outdoors, it seems odd to me that so many people wonder if solar backpacks can handle rain.
Solar backpacks are just as durable as your average backpack and many times even more so. While no backpack is likely to be 100% waterproof, solar packs are almost certainly going to be water-resistant.
KEY POINT: Basically questions about solar backpacks usually revolve around how the panels hold up. Solar panels themselves are waterproof, resilient, and designed to get through any weather!
That being said, it is important to take certain precautions. In the same way you wouldn't just jam your laptop into a backpack with no raincoat or protective poncho over the top when it was pouring rain outside, you should take all precautions when using a solar pack.
That has to do with water soaking through backpack material, not whether a pack is solar or not.
As for charging electronics while going through rain, if you have a full cover poncho so no rain is getting through then you should be fine.
Believe it or not, the solar backpacks are still pulling in solar energy during cloudy or rainy weather.
The amount being pulled in is much lower than on a sunny day, but the panels are still working to pull what little energy they can even during inclement weather.
This is a pleasant surprise for many people, as is finding out that portable solar panels can charge via LED lights indoors.
But the solar panels you will find on modern backpacks are designed to go through the wear and tear that they will see through everyday life and use.
Solar Power Made Practical Use
Solar power backpacks are meant to be reliable. Because of the long-time negative news campaigns run against solar power decades ago, there's an unfair (and normally not true) perception of solar as being unreliable.
Which means solar gear needs to work at a higher standard just to get the benefit of the doubt.
So when people ask are solar backpacks reliable the answer needs to be far more enthusiastic than a tepid yes.
This is why many items that are solar powered are built as good or even better than the standard non-solar equivalents.
Your solar backpack will be fine in the rain as long as you take the regular precautions you would with any other backpack.
Quality of Backpack Matters
As with regular backpackers, the quality of the brand of backpack you buy matters when seeing how well your solar backpack will function and hold up.
If you pay for cheap you will get cheap.
The top brand solar backpacks are exceptional. There are even companies that really focus on making solar packs for hikers and backpackers. Obviously these must be able to hold up against inclement weather.
The chances of hiking for three months without getting caught in the rain are going to be next to nothing.
Unless you're doing a desert hike, in which case you wouldn't be worrying about how rain proof or water resistant your pack is.
But if you go with a quality solar backpack, you won't have to worry about that.
We talk about some of our favorite picks for solar backpacks in the "Are solar backpacks reliable?" that we linked to a bit further up.
If you're lazy the picks basically are (with links to up to date Amazon listings):
A good solar backpack will be water resistant and the solar paneling will be just fine no matter how much the water comes down.
How Resilient Solar Panels Are in Storms: A Personal Experience
We survived the horrific Derecho in Cedar Rapids, IA back in 2020. To put the short summary, including those asking "What the heck is a Derecho?" Imagine a category 3 hurricane at full force for two to three hours slamming into the middle of the Midwest of the United States.
A place not exactly known for hurricanes, to put it mildly.
The city was smashed, and large chunks had no power for three weeks. Virtually every house within five blocks had roof damage. At least the ones that still had roofs.
Ours was undamaged. Even the "I don't know how much I trust that structure much less roof" garage (which also has some solar panels on it).
Those solar panels were like Viking shields. Terrifying new weather condition unlike any ever seen in Iowa's history?
Wind, rain, giant tree branches, the panels couldn't care less.
Granted – those are full scale solar panels for homes and buildings versus the smaller portable solar panels put onto backpacks.
But it goes to show that solar panels in all their forms aren't considered about rain, sleet, or snow.
If this seems amazing keep in mind they have already developed solar panels that harvest additional energy from rain drops.
As anyone who has watched solar grow over the past 20 years, the technology is only going to continue to get better and better.
The Verdict: Solar Backpacks Work Well in Rain
The only major difference between solar backpacks and regular packs is that the solar packs give you the option of harnessing solar power in order to charge electronics like smartphones, laptops, or tablets.
These will be just as water resistant as most well built backpacks while helping you to keep important electronics charged even when you're a long way from the nearest charging port.
As long as you stay with the proven dependable solar backpack brands you can rest easy knowing that your solar backpack will function just fine in the rain.
Hi, I'm Shane! I've always felt a passion for two worlds: one in technology and one for the great oudoors away from it. The amazing advances in solar power in my lifetime have really opened up the possibilities, and both my brother and I are deeply passionate about where solar power meets outdoor gear!

text: We present an approach to the cache bottleneck problem using reversible logic circuits. The high traffic between the cache and the main memory in current systems considerably slows down the performance of the general information processing unit (IPU). Moreover this high traffic has the consequence of high heat generation in VLSI elements such as the CPU or dedicated processors. Thus the reduction in use or complete removal of the cache memory could be beneficial to current processors architecture. We present a model where the IPU is designed as a logically reversible circuit. This allows one to reduce the cachememory traffic because data can be recovered using the output of the current processing. We illustrate the implementation of the approach by providing a design of an adiabatic reversible Toffoli gate with a power consumption equivalent to a classical adiabatic circuit. With these approaches, the cache-memory bottleneck and heat dissipation can potentially be reduced even by using only logically reversible circuit implementation.

Hindi/Urdu: baiThnaa vs. baiTh jaana or baiTh lenaa
Discussion in 'Indo-Iranian Languages' started by eskandar, Oct 4, 2013.

 What are the semantic differences between these three verbs? My feeling is that while baiThnaa is the basic verb, baiTh jaana conveys motion ("to go sit") and baiTh lenaa would be equivalent to the English "to take a seat". Have I understood correctly?
 It also seems to me that, for example, baiTh jaa'o would be a more direct (maybe even more forceful?) command ("go sit down!") compared to baiTh lo ("take a seat"). Is that right?
 Finally, I would appreciate recommendations for a good (preferably somewhat comprehensive) source for these types of compound verbs in Hindi/Urdu. Dictionaries typically offer only the simple verb form, so aside from listening to contextual use it's hard to know when to say X karo vs. X kar lo or what have you, and I fear that my over-reliance on simple (non-compund) verbs makes my speech sound stilted.

 eskandar SaaHib "baiThnaa" on its own means both "to sit" and "to sit down". The "jaanaa" in "baiTh jaanaa" to the best of my understanding has not to do with the person going from A to B but (possibly) his stature going from a sanding position to a seated position. Therefore, if my logic is correct,"baiTh jaanaa" is a more emphatic form of "baiThnaa". Let's use a couple of very simple sentences.
 e-SaaHib yahaaN baiThiye
 e-SaaHib yahaaN baiTh jaa'iye
 To me, the latter gives not only more emphasis to the act of sitting but also it seems politer than just saying "baiThiye".
 I am not aware of "baiTh lenaa" but for the causative "biThaanaa", one has "biThaa lenaa/denaa".
 B. SaaHib ne e-SaaHib ko apne paas biThaa liyaa aur kuchh raaz-daarii kii baateN karne lage!
 A. SaaHib ne Lakhnau kii sair karaane kii xaatir hameN ek sunsaan kuuche meN biThaa diyaa aur xud nah jaane kahaaN Ghaa'ib ho ga'e!
 Platts does go into compound verbs but I am not aware of a book on compound verbs as such. Any good grammar book covers this aspect of Urdu and Hindi.

 eskandar SaaHib, jaanaa in these verbal forms does not relate to motion (go and...). They need not be translated by parsing them. They cover an aspect of a verb, that is completion. They do provide an emphatic tone and while I agree with QP SaaHib's remarks, suppose I am shouting baiTho! it will not have this effect when I shout baiTh jaa'o! The stress is on jaa'o. I imagine it, in the terms of language, as... baiTh[e hu'e ho ]jaa'o, equivalent to become seated - the action should be completed.
 khaanaa khaa'o - can mean both do start eating or eat it up
 khaanaa khaa jaa'o means eat your food up.
 You cannot parse it and translate, like in '' maiN uTh baiThaa''. May I ask you how you understand this sentence?

 Thanks, both of you.
 I thought I had heard "baiTh lo" used but perhaps I misheard. (Is anyone else familiar with this compound?)
 Thanks QP SaaHib, I found an overview in Schmidt's "Urdu: An Essential Grammar" which was useful but not as comprehensive as I'd like.
 That's a very helpful way of thinking about it, thank you marrish SaaHib.
 If I understand it correctly, it's idiomatic and means "I got up/sat up". So your point is well-taken that I should similarly understand "baiTh jaana" as a single unit of meaning and not parse it according to its individual parts.

 eskandar Sb. as has been conveyed to you the term jaanaa here doesn't imply / indicate motion but is a more emphatic means of saying something and it also has nothing to do with a change in stature from standing to sitting position!
 We also say khaa / k_haa jaanaa (to devour; eat / consume (destructively).) instead of khaanaa /k_haanaa (verb, to eat), naaraaDh (ناراض) ho jaanaa, bigaR (بگڑ) jaanaa, etc. etc.

text: ISIS Spectrograph Automatic Active Collimator (ISAAC) was developed at the Optical Science Lab, University College London, as an experimental system to improve the image stability on the detectors of the Intermediate-dispersion Spectroscopic and Imaging System (ISIS) at the William Herschel Telescope (WHT). It is based on the concept of active compensation, where spectrum drifts, owing to the spectrograph flexing under the effect of gravity, are compensated by the movement of an active optical element. ISAAC is a fine-steering tip-tilt collimator mirror; it was tested on the spectrograph in 1995 July. Here we report the details of the design and the laboratory tests together with the results of the experiment on ISIS at the WHT. The experiment shows that active compensation can reduce flexure down to less than 3 μm over 4 h of telescope motions, dramatically improving the spectrograph performance. A way of implementing ISAAC as a common user facility is briefly discussed, together with a study of the characteristics of flexure in ISIS.

The birthing body has been a site for locating competing claims of control from much before the birth of modern medical knowledge, and the contestation carries on in our contemporary. What makes for variety within this long-standing contestation are of course the shifting terms of conflict. Broadly divided into three parts, this paper shall document the different formats and priorities of the contestation project, which has actually been synonymous with a contestation between the human attendants of birth. While in preand early modern times, especially in Western Europe, this conflict played out between female and male healers, primarily over the use and abuse of'supernatural power', 19th century colonial Indian modernity saw the conflict played out between institutionalization of the elite birthing body and the collective of indigenous (i.e., 'non-modern') birth attendants. In the contemporary the contestation plays out between statist development, and a rather fleeting and often vacuous category of the traditional birth attendant.
Through these three sections what the paper shores up is the rather dynamic nature of violence that has – largely surreptitiously – been precipitated on the female, indigenous birth attendant by the male indigene, by the institution of modernity/obstetrics and by the development state.

Localized charge bifurcation in the coupled quantum dots
We analyzed theoretically localized charge relaxation in a double quantum dot (QD) system coupled with continuous spectrum states in the presence of localized electrons Coulomb interaction in a single QD. We have found that for a wide range of system parameters charge relaxation occurs through two stable regimes with significantly different relaxation rates. A peculiar time moment exists in the system at which rapid switching between stable regimes takes place. We consider this phenomenon to be applicable for creation of active elements in nano-electronics based on the fast transition effect between two stable states.

Gap Effect on Performance of Podded Propulsors in Straight-Ahead and Azimuthing Conditions
Abstract:This paper presents results of an experimental study on the effect of gap distance on propulsive characteristics of puller and pusher podded propulsors in straight-ahead and static azimuthing open-water conditions. The gap distance is the axial distance between the rotating (propeller) and stationary (pod) parts of a podded propulsor. The propeller thrust and torque, unit forces, and moments in the three-coordinate directions of a model podded unit were measured using a custom-designed pod dynamometer in various operating conditions. The model propulsor was tested at the gap distances of 0.3%, 1%, and 2% of propeller diameter for a range of advance coefficients combined with the range of static azimuthing angles from +20° to 20° with a 10° increment. The tests were conducted both in puller and pusher configurations in the same loading and azimuthing conditions. In the puller configuration, the gap distance did not have any noticeable effect on propeller torque in straight course condition, but had an effect in azimuthing conditions. The propeller thrust and efficiency were also influenced by the change of gap distance, and the effects were more pronounced at high azimuthing angles and high advance coefficients. For pusher configuration, however, the gap distance did not affect the propeller performance characteristics in straight-ahead and azimuthing conditions. Both in straight course and azimuthing conditions, the unit thrust and efficiency were not influenced by the gap distance in either puller or pusher configurations. The gap distance had a noticeable effect on unit transverse force and steering moment both in puller and pusher configurations, and both in straight course and azimuthing conditions. An uncertainty estimate of the measurements is provided at the end.

A Beginner's Guide to Using Lodash with Angular
Step 1: Install Lodash
The first step is to install Lodash. You can install Lodash using npm. Open your terminal and type the following command:
npm install --save lodash
Step 2: Import Lodash
After installing Lodash, you need to import it into your Angular project. You can import Lodash in your component file or in your AppModule file. Here is an example:
import * as _ from 'lodash'; // Import Lodash
Step 3: Use Lodash
Once you have imported Lodash, you can start using its functions in your Angular application. Here is an example of how to use the
const numbers = [1, 2, 3, 4, 5]; const squaredNumbers = _.map(numbers, (number) => number * number); console.log(squaredNumbers); // [1, 4, 9, 16, 25]
In the above example, we used the
_.map() function to square each number in the array.
Lodash is a powerful utility library that can simplify your code and make it more readable. By following the above steps, you can easily use Lodash with your Angular application. Happy coding!
10 Ways to Simplify Your Angular Code with Lodash
- Iterating over arrays and objects: Use
_.mapinstead of for loops.
- Filtering arrays: Use
- Finding values in arrays: Use
- Sorting arrays: Use
- Combining arrays: Use
- Merging objects: Use
_.mergeinstead of writing your own code.
- Cloning objects: Use
_.cloneDeepinstead of writing your own code.
- Transforming arrays: Use
_.groupByinstead of writing your own code.
- Checking types: Use
- Working with numbers: Use
_.randominstead of writing your own code.
By using Lodash in your Angular app, you can simplify your code and make it more readable. With these ten tips, you can start using Lodash to make your code more efficient today!
Why Lodash is the Perfect Complement to Angular
When it comes to building Angular applications, Lodash can be a valuable complement to the framework. Here's why:
- Provides utility functions for data manipulation: Lodash provides a wide range of utility functions that can help you manipulate data easily. Some of the most commonly used functions include
- Improves code readability: By using Lodash, you can write more concise and readable code. Since Lodash functions are named clearly and are easy to understand, your code will be more maintainable and easier for other developers to read and work with.
- Optimizes application performance: Lodash is designed to be efficient and high-performing. By using Lodash functions instead of writing your own code, you can reduce the amount of code you need to write, improve the performance of your application, and reduce the risk of bugs.
Overall, Lodash is an excellent complement to Angular. It can help you write more efficient, readable, and maintainable code, while also improving the performance of your application.
Using Lodash to Improve Performance in Angular Applications
Another useful feature of Lodash is its support for method chaining. Method chaining allows you to string together several operations on a collection or object to perform complex manipulations in a single line. This results in efficient, readable, and concise code that is easy to debug.
Lodash also includes a number of utility functions that can help you simplify other common tasks in your Angular application. For example, it provides methods to deep clone objects, merge objects, generate unique IDs, and perform various math operations.
In conclusion, Lodash is a powerful toolkit that can help you achieve better performance, cleaner code, and more efficient development in your Angular applications. By leveraging this library, you can streamline your coding process and ensure that your application runs smoothly, even when working with large data sets.
Streamlining Your Angular Workflow with Lodash
In an Angular project, you can easily add Lodash to your workflow by installing it as a dependency and importing the functions you need. Here are a few examples of how Lodash can help you streamline your Angular code:
- Use the
_.mapfunction to transform data arrays into a different format.
- Use the
_.filterfunction to search for specific items in an array.
- Use the
_.orderByfunction to sort arrays by specific criteria.
- Use the
_.groupByfunction to group data by specific properties.
These are just a few examples of the many ways that Lodash can help you write more efficient and maintainable code in your Angular projects. So if you haven't already, consider adding Lodash to your toolbox and see how it can improve your workflow.
How Lodash can Help You Handle Data and Arrays in Angular
In Angular, dealing with data and arrays is a common task. It involves numerous efforts and is susceptible to bugs if not handled accurately. Fortunately, Lodash makes it easier to manipulate data and arrays in Angular.
Here are a few ways Lodash can help you with data and arrays in Angular:
- Manipulating Arrays: Lodash provides an extensive range of functions to work with arrays, such as finding elements, transforming them, filtering them, and more.
- Working with Objects: Lodash also provides several useful functions for working with objects, such as finding keys, values, merging objects, and more.
- Deep Cloning: Lodash's deep clone method can help you create a complete, deep copy of an object or an array and avoid any accidental reference to the original object.
Lodash can also help you deal with complex data structures and nested lists in Angular.
Using Lodash with Angular is a piece of cake: you only have to install it and import the required module into your Angular component. Once you do that, you can start using any of these functions in your code right away.
To sum up, Lodash can save you considerable development time and effort when dealing with data and arrays in Angular. Additionally, its intuitive interface makes it easy to use, and its extensive documentation is a bonus for newcomers.
8 Lodash Functions Every Angular Developer Should Know
As an Angular developer, you will often work with arrays, objects, and other complex data types. In such cases, Lodash can come in handy with its utility functions that simplify your code and make it more efficient. Here are eight Lodash functions that every Angular developer should know:
1. map(): This function creates an array of values by running each element in the input array through a callback function.
2. filter(): This function creates an array of elements from the input array that satisfy a given condition based on a callback function.
3. reduce(): This function reduces an array to a single value by iterating over its elements and applying a callback function that accumulates the values.
4. clone(): This function creates a shallow clone of an object or array, meaning it copies the values of the original object into a new object with the same structure.
5. merge(): This function merges two or more objects into a single object, with the property values from later objects overwriting those from earlier ones.
6. debounce(): This function limits the rate at which a function can be called to prevent it from being called too frequently, which can cause performance issues.
7. throttle(): This function limits the rate at which a function can be called by postponing subsequent calls until after a certain amount of time has elapsed since the last call.
8. shuffle(): This function shuffles the elements of an array in a random order, which can be useful for randomizing data or creating a game.
By using these Lodash functions, you can make your Angular code more efficient, readable, and maintainable.


A SCience Odyssey Radio Transmission
How is a Radio Wave Emitted?
Diagram of atoms within a wire showing movement of electrons between atoms
OK. So we have a signal that is sent to a radiosmitter's antenna. How does that signal get from the antenna to the air?
Let's first take a look at the signal. The signal is an electic current, and every electric current is actually electrons moving in a wire.
Wire is made of metal, usually copper. All of the atoms that make up the wire have something in common -- each has one or two electrons in its outer-most shell.
These electrons do not have a strong bond with the rest of the atom. In fact, it takes just a slight amount of energy to push the electron away from its atom.
But if you have enough energy, the outer electrons from all of the atoms will move at once. They will each travel from one atom to the next atom, and so on.

Now that we have looked at editing existing sounds, let's start creating some new ones from scratch.
- In an empty part, go to the Main > Edit view. In the Mapping Editor, right-click and choose Create Keygroup > Synth Template.
- A new keygroup has been created, mapped to the full key and velocity range.
- Play a few notes, and you will hear a simple sine wave oscillator. Let's change that to a sawtooth wave, by clicking the Waveform and choosing Sawtooth from the menu.
- We can continue building our sound by editing the other synth engine parameters, such as enabling Stereo mode and adding additional voices.
- To stack multiple synth sounds, we can add a second synth keygroup. Let's choose Create Keygroup > Synth Template a second time, and another keygroup will be stacked on top of the first. For this keygroup, let's choose one of the oscillator's factory presets, such as "Accordion".
- Perhaps instead of stacking these sounds, this could be a split program instead, with one sound for the left hand and another for the right hand. To do that, we'll need to adjust the key ranges of the keygroups so they don't overlap. Right-click in the Mapping Editor and choose Select All, then choose Resolve Overlapping Key Range.
The keygroups can now be easily edited separately. For example, the key and velocity ranges could be further adjusted by dragging the edge of the keygroup.


Cylindrical Eigenfunction Expansion
From WikiWaves
Jump to: navigation, search
Introduction
There are any situations where we want to expand the three-dimensional linear water wave solution in cylindrical co-ordinates. For example, scattering from a Bottom Mounted Cylinder or scattering from a Circular Floating Elastic Plate. In these cases it is easy to find the solution by an expansion in the cylindrical eigenfunctions. If the depth dependence can be removed the solution reduces to a two dimensional problem (see Removing The Depth Dependence). While the theory here does apply in this two dimensional situtation, the theory is presented here for the fully three dimensional (depth dependent) case. We begin by assuming the Frequency Domain Problem.
Outine of the theory
The problem for the complex water velocity potential in suitable non-dimensionalised cylindrical coordinates, [math]\phi (r,\theta,z)[/math], is given by
[math] \frac{1}{r} \frac{\partial}{\partial r} \left( r \frac{\partial \phi}{\partial r} \right) + \frac{1}{r^2} \frac{\partial^2 \phi}{\partial \theta^2} + \frac{\partial^2 \phi}{\partial z^2} = 0, \quad (r,\theta,z) \in \Omega [/math]
[math]\frac{\partial \phi}{\partial z} = \alpha \phi , \quad z=0 [/math]
[math] \frac{\partial \phi}{\partial z} = 0, z=-h [/math]
In three-dimensions the Sommerfeld Radiation Condition is
[math] \sqrt{|\mathbf{r}|}\left( \frac{\partial}{\partial|\mathbf{r}|} - \mathrm{i} k \right) (\phi-\phi^{\mathrm{{I}}})=0,\;\mathrm{{as\;}}|\mathbf{r}|\rightarrow\infty\mathrm{.} [/math]
where [math]\phi^{\mathrm{{I}}}[/math] is the incident potential.
The solution of the problem for the potential in finite water depth can be found by a separation ansatz,
[math] \phi (r,\theta,z) =: Y(r,\theta) Z(z).\, [/math]
Substituting this into the equation for [math]\phi[/math] yields
[math] \frac{1}{Y(r,\theta)} \left[ \frac{1}{r} \frac{\partial}{\partial r} \left( r \frac{\partial Y}{\partial r} \right) + \frac{1}{r^2} \frac{\partial^2 Y}{\partial \theta^2} \right] = - \frac{1}{Z(z)} \frac{\mathrm{d}^2 Z}{\mathrm{d} z^2} = k^2. [/math]
The possible separation constants [math]k[/math] will be determined by the free surface condition and the bed condition.
Separation of variables for a free surface
We use separation of variables
We express the potential as
[math] \phi(x,z) = X(x)Z(z)\, [/math]
and then Laplace's equation becomes
[math] \frac{X^{\prime\prime}}{X} = - \frac{Z^{\prime\prime}}{Z} = k^2 [/math]
The separation of variables equation for deriving free surface eigenfunctions is as follows:
[math] Z^{\prime\prime} + k^2 Z =0. [/math]
subject to the boundary conditions
[math] Z^{\prime}(-h) = 0 [/math]
and
[math] Z^{\prime}(0) = \alpha Z(0) [/math]
We can then use the boundary condition at [math]z=-h \, [/math] to write
[math] Z = \frac{\cos k(z+h)}{\cos kh} [/math]
where we have chosen the value of the coefficent so we have unit value at [math]z=0[/math]. The boundary condition at the free surface ([math]z=0 \,[/math]) gives rise to:
[math] k\tan\left( kh\right) =-\alpha \, [/math]
which is the Dispersion Relation for a Free Surface
The above equation is a transcendental equation. If we solve for all roots in the complex plane we find that the first root is a pair of imaginary roots. We denote the imaginary solutions of this equation by [math]k_{0}=\pm ik \,[/math] and the positive real solutions by [math]k_{m} \,[/math], [math]m\geq1[/math]. The [math]k \,[/math] of the imaginary solution is the wavenumber. We put the imaginary roots back into the equation above and use the hyperbolic relations
[math] \cos ix = \cosh x, \quad \sin ix = i\sinh x, [/math]
to arrive at the dispersion relation
[math] \alpha = k\tanh kh. [/math]
We note that for a specified frequency [math]\omega \,[/math] the equation determines the wavenumber [math]k \,[/math].
Finally we define the function [math]Z(z) \,[/math] as

as the vertical eigenfunction of the potential in the open water region. From Sturm-Liouville theory the vertical eigenfunctions are orthogonal. They can be normalised to be orthonormal, but this has no advantages for a numerical implementation. It can be shown that
[math] \int\nolimits_{-h}^{0}\chi_{m}(z)\chi_{n}(z) \mathrm{d} z=A_{n}\delta_{mn} [/math]

Separation of Variable for the [math]r[/math] and [math]\theta[/math] coordinates
For the solution of
[math] \frac{1}{r} \frac{\partial}{\partial r} \left( r \frac{\partial Y}{\partial r} \right) + \frac{1}{r^2} \frac{\partial^2 Y}{\partial \theta^2} = k_m^2 Y(r,\theta), [/math]
we use the separation
[math] \,\!Y(r,\theta) =: R(r) \Theta(\theta). [/math]
Substituting this into Laplace's equation yields
[math] \frac{r^2}{R(r)} \left[ \frac{1}{r} \frac{\mathrm{d}}{\mathrm{d}r} \left( r \frac{\mathrm{d} R}{\mathrm{d}r} \right) - k_m^2 R(r) \right] = - \frac{1}{\Theta (\theta)} \frac{\mathrm{d}^2 \Theta}{\mathrm{d} \theta^2} = \eta^2, [/math]
where the separation constant [math]\eta[/math] must be an integer, say [math]\nu[/math], in order for the potential to be continuous. [math]\Theta (\theta)[/math] can therefore be expressed as
[math] \Theta (\theta) = C \, \mathrm{e}^{\mathrm{i} \nu \theta}, \quad \nu \in \mathbb{Z}. [/math]
We also obtain the following expression

Ever find yourself doing something without knowing exactly why? You might swat at a fly before you consciously realize it is there, or you might catch yourself scratching a bug bite you were trying to forget about. A new study published in Psychological Science could help explain why: half of the brain can be subliminally motivated while the other half is left in the dark.
Researchers at INSERM in Paris first measured how hard 33 subjects could squeeze a grip with each hand. Then they presented the subjects with images on a computer screen of either a one-euro coin or a one-cent coin. The coins were visible to only one eye at a time, and they appeared for only 17 milliseconds—long enough for subliminal, but not conscious, processing. After each coin image flashed, the subjects squeezed the grip with whatever hand they were holding it in—they were told they would win a fraction of the coin's value depending on the amount of effort they exerted. Each subject got to try all four possible combinations of eyes and hands: right eye with right or left hand and left eye with right or left hand.
Although the subjects could not correctly guess which coin they had seen—confirming that they were not conscious of what they saw—they squeezed harder when presented with the larger coin if the hand grip was on the same side of the body as the eye that had seen it. Their squeezes did not change depending on what the opposite eye saw, indicating that only half the brain was being motivated at a time. Motivation, therefore, is sometimes not only subconscious, explains co-author and INSERM cognitive neuroscientist Mathias Pessiglione, but it can also be "subpersonal," in that "one part of a person can be motivated while the other is not." So next time you are surprised to find yourself midaction, consider blaming it on the independent halves of your brain.

International Agricultural Study Tours
Michigan farmers do business in a global marketplace, so it makes sense that they visit other countries to learn:
- Where U.S. agricultural exports go,
- Where U.S. agricultural imports originate, and
- How agriculture in other parts of the world compares to ours.
International agricultural study tours are made possible by Michigan Farm Bureau and the Michigan Foundation for Agriculture.
Passport to Learning
Each tour develops a unique itinerary and focus based on interaction with host farms and counterpart agricultural organizations, industry representatives and government officials. Along the way, participants evaluate potential market opportunities and competition, evaluate their peers' adaptation of technology and consider each nation's take on farm and food policy.

There are various methods of storing and retrieving both data and ready information in computers from primary to secondary storage systems. Data may be stored in different storage devices in the computer. There are three basic methods used to retrieve data from computers;
Sequential Access Method
This method of data access is for example applied on reel type magnetic tapes. The data is stored in a logical sequence. The data that was stored first will appear first in the storage device. To find any specific file the device starts searching from the beginning and goes through all files till it finds the specified data.
For example in magnetic tapes the device has to rewind to the beginning each time a file is searched and look in sequence till it finds the specified one. The rewinding and searching makes sequential access devices practically slower.
Direct Access Method
In direct access method, the device can retrieve the required piece of data directly without the need of any sequence. Though data in direct access devices can be accessed sequentially but it is much slower that way. The devices are subdivided into various locations and each location is assigned an address. Each piece of data is stored in these addresses. When the computer is asked to search for a specific file, it searches for the assigned address of that file.
The address helps the computer go straight to specific data without having to go through every file in the storage devices. This is what makes direct access devices much faster than sequential devices.
Indexed File Access Method
Indexed access method can be described as a hybrid; it is a cross between sequential and direct access methods. Storage of the data in a device is done using sequential method. Each record is then assigned two codes a primary key and a secondary key.
The primary key is a type of identification code and appears first in the record name. It can for example be a social security number or any suitable identification format. It works as the locator number of that record. Primary keys are stored sequentially so that within a given block of data the specific records can be randomly stored. An index at the beginning of this block of data is used to identify all the records in it. After finding the index of the block of data the computer proceeds to find the primary key of the records.
The secondary key serves as the full identification of the record. It is used to exactly locate the specific item. The secondary key tells the computer specifically where the out of sequence item can be found.

An English editor is a person who is engaged in the work of editing the manuscript or the written text that has to be published. The editor is an expert in the language and has good command over the language in which he is doing the work of editing.
In the modern days English is developing as the common language that is being used in writing and in the corporate world. An editor is needed in both the sectors that is, in creative writing and for editing the written documents, mails and other texts which are commonly used in business dealings.
Importance of English Editor
The editor plays an important role in the publication and business sector as it is in his hand to detect all the errors that occur during writing and rectify them before it is finally published or sent to the concerned recipient. The editor has to do to two types of editing.
One is copyediting which is commonly known as proofreading and the other is content editing which is related to higher level of editing as the editor makes major changes in the original manuscript so that the ideas of the writer is brought to a level which can be easily understood by the reader.
A good editor must have good command over English language and through knowledge of grammar as he has to ensure that the final copy that is sent after editing is correct, comprehensible, the ideas are clear, there is a consistency in the text and the text is concise. Professional English editors are very helpful for people who use English as a second language.

The term is sometimes confused with Mesolithic, and the two are sometimes used as synonyms. Yet, when a distinction is made, Epipaleolithic is used for those cultures that were not much affected by the ending of the Ice Age and the term Mesolithic is reserved for Western Europe where the extinction of the Megafauna had a great influence on the paleolithic populations at the end of the Ice Age.

Is 'laughing gas' a security concern?
September 26, 2014 − by SFS Ltd − in News − Comments Off on Is 'laughing gas' a security concern?
proof-of-age-cardNitrous oxide, also known as 'laughing gas' is a legal drug that becomes popular amongst young people, due to its effects similar to those of hard drugs such as heroin and crack cocaine. Inhaled from party balloons, 'laughing gas' creates hallucinations and a sense of short time euphoria.
According to medical professionals, inhaling 'laughing gas' can have the effect of fainting, regular use of this party drug could be even fatal.
Home Office statistics showed that 'laughing gas' is, after cannabis, the second most popular drug among people aged 16 to 24.
But despite of health warnings and even Home Office recommendations that festivals should crack down on 'laughing gas', the drug remains legal to inhale.
In a BBC investigation, security was criticised that they stood by and did nothing, allowing consumption of laughing gas at one of the UK's top dance festivals.
So, is 'laughing gas' a security concern?
Obviously, even though this is a legal drug, the risk of having customers passing out due to nitrous oxide is a security concern. This can be controlled by conducting searches, not allowing entry to or ejecting those who are expected to inhale the gas.
A "zero tolerance" attitude to drugs is always a good practice, regardless of whether the substance was illegal or not.

The Jaws of Life are actually a set of rescue tools
made by several different companies. This includes Hurst (who hold the trademark for Jaws of Life), Amkest, and others.
These tools are hydraulic powered, and have many different uses. There are four main types of tools:
- Spreaders - Used to open doors by applying an unbelievable amount of pressure to the door to pop the Nader pin. We usually can open a door in under a minute with them. They are also used to do an emergency dash roll (discussed below)
- Cutters - These are used to, well, cut things. Generally these are used when opening the door is either not feasable, or would not provide enough access. We would then cut the door posts, and take the roof off to access the patient.
- Combination tools - these tools have both spreaders and cutters built in to them. Good for departments with not a lot of room on their fire trucks.
- Rams - These are used to push things. Generally we would use these if someones legs were trapped under the dash. We would put one end in the corner of the door, and extend the other until it push the dash as far as we needed it to go (or as far as the tool will let us).
Besides Hydraulic tools, there are a myriad of hand tools
that can be used. For example, a crash axe
has a point and axe on one end, and a can-opener looking contraption on the other. Generally we can take the roof off of a car with a crash-axe, a metal hand-saw, and a jar of dish soap in the time it takes them to set up the hydraulic tools.
We have also used the tools to assist the sheriff's office with forcing entry into a house, for tearing down a swingset, and other rescues.

Development of Guqin cultural practice activities
From December 26th to 27th, our college organized more than 80 students from Hong Kong, Macao, and Taiwan to go to Zhangzhou Longren Guqin Cultural Village to carry out cultural practice activities to learn the connotation of Chinese culture in depth.
In the Longren Guqin Cultural Village, the students learned the basic knowledge of the guqin, "hook", "picked", "prose", "overtone" and other fingering techniques, played "Deng Guan Que Lou" and other repertoires; tried Teng style butterfly painting learning Chen Jun, the eighteenth-generation successor of Teng school butterfly painting, and representative inheritor of the Teng school butterfly painting technique of Xiamen's intangible cultural heritage protection project teaches students the history of Teng school butterfly painting and butterfly painting techniques.
Liang Yuan, a student from Taiwan, said: "It is antique here, and you can also learn to play the guqin and paint butterflies. It is like entering the mind of an ancient poet, allowing us to learn more about Chinese culture and have a deeper understanding."
It is reported that carrying out cultural practice activities is one of the important forms of education about the national conditions of Hong Kong, Macao, and Taiwan overseas Chinese students in our college. Going out of the campus and going deep into the society, Hong Kong, Macao, and Taiwan overseas students can understand the profoundness of learning Chinese traditional culture, enhance cultural identity, and promote Chinese culture.

INA – Intelligent Anomaly Detection for miniaturized sensor systems and data loggers
The aim of the subproject "piSmart-Ina" is the recognition and visualization of anomalies based on heterogeneous sensor data collected with intelligent data loggers. This involves analyzing data with pattern recognition methods and porting anomaly classifiers from analysis platforms to the data loggers so that they are independent and autarkic.
Companies and Developers.
For the development of machines or condition monitoring of machines, animals, or humans, it makes sense to obtain and understand the current situation or operating conditions. For this reason, data recording systems are available in the market, which can store one or more sensor values. By collecting different signals, a new quality of information provision is possible by incorporating machine learning methods. While up to now sensor data has been stored by data logger and subsequently analyzed extensively by experts, the project is developing an autonomous system for automated pattern and anomaly detection from stored sensor data.


inheritance of x's property a is overridden in xi and makes it pretty much behave as if nothing was inherited. JSON.stringify itself ignores inherited values - it only translates the enumerable own properties as given by Object.keys(y). The default stringification, while not encoding inheritance, can (except for undefined values) encode enough of an object to reconstruct it in an environment that knows what inheritance it should have. To encode JavaScript objects that contain explicit undefined values a convention for representing undefined must be established, such as mapping it to the string "UNDEFINED". One can then pass JSON.stringify the optional replacer argument to translate with this convention:
 var y = {a: undefined};
 var ys = JSON.stringify(y,
 function (k, v){return (v === undefined) ? "UNDEFINED" : v});

 Converting this JSON back into JavaScript is not as straightforward. While JSON.parse can take an optional reviver argument that is, essentially, the inverse of a replacer, it can't be used in this situation. If that function returns undefined, the JSON.parse logic interprets this to mean to not define a property rather than define one with a undefined value. Instead one has to explicitly post process the result from JSON.parse replacing each "UNDEFINED" with undefined.

Throttle Modes
From Train Control Systems Documentation
Jump to navigation Jump to search
Overview
Check out our video overview of all of the Throttle Modes available in TCS WOWSound, or continue reading for detailed descriptions of each mode individually
Prototype Throttle Mode
Proto Notch
Proto Notch™ is the TCS exclusive approach to matching the motive power sounds of your model locomotive with the prototype. Using our advanced BEMF motor algorithm, Proto Notch™ decoders can sense exactly how much force is being applied to the rails to move your locomotive and train. By matching that information with prototype performance, we can scale the effort of the model to the real thing and play the right sound to match the work being done.
WOWDiesel
WOWDiesel decoders are configured with diesel-specific prototypical notching. The WOWDiesel decoder selects which notch (1-8) the prototype locomotive would have to be in to haul your scale load at your scale speed. Then it plays the corresponding prime mover sound to emulate the correct power for that notch.
WOWSteam
WOWSteam decoders are configured with variable chuff intensity to emulate prototypical throttling. Your locomotives will make faster and harsher chuff sounds as you ramp up speed or increase the load, and soften to slower and smoother chuffs under lighter loads and less pressure. When the locomotive is coasting, rod clanks and snifters also activate depending on coasting rate and track grade.
The video below can teach you all you need to know about Prototype Throttle Mode:
WOWDiesel Auto Notching
TCS brought auto notching to the model train hobby with the advent of the very first WOWDiesel decoder. It is arguably the coolest feature of the WOWSound decoder!
Auto notching is only available in the Prototype Throttle Mode. Auto notching allows the decoder to sense the load it is under, and decide what notch to be in. Auto notching is unlike Traditional Throttle Mode where the active notch is based exclusively on the speed. With Auto notching the prime mover sound is constantly changing as it goes up hills, around curves, picks up more cars, and coasts down hills!
In order to make the best use of auto notching, you must calibrate the locomotive in Audio Assist® so it knows what the ruling grade is on your layout and will be in notch 8 as it traverses it. Every locomotive is different, both in the sense of unqiue characteristics of the motor and gearing, as well as the "normal" operating conditions in which you run it. All of these factors need to be accounted for, and thus a calibration is needed in order for the decoder to "learn" your railroad.
To calibrate your WOWDiesel locomotive so that it knows the ruling grade and downhill grades on your layout enter Audio Assist® and go to the calibration menu (menu 3.2) and follow the audio prompt from the decoder. It will ask you to run the locomotive in a coasting condition and then a notch 8 condition. (PRO TIP: While on the calibration menu you can calibrate the coasting point by pressing function 1 or the notch 8 point by pressing button 2, even if the menu is telling you to do otherwise)
Behind the scenes Audio Assist® is saving the calibration data to indexed CV4:17 BEMF Calibration Low and CV4:18 BEMF Calibration High both CV's can be programmed tweaked manually. TCS recommends calibrating using Audio Assist® and then manually tweaking the CV's if need be.
WOWSteam Auto Chuff Intensity
WOWSteam Auto Chuff Intensity
Other Prototype Throttle Mode Features
In Prototype Throttle Mode, the default momentum values are set to the "Mainline Momentum" values stored in the decoder as part of the Momentum Modes feature. The Mainline Momentum values are typically high momentum values which create a more realistic operating experience. The higher momentum values require you to use the Train Brake to slow down your train, rather than simply using the speed control on your throttle.
Traditional Throttle Mode
Traditional throttle mode is how sound decoders of the past would "traditionally" operate, where the chuff intensity was one constant volume, or the prime mover notch is related directly to the speed. E.G. every (n) speed steps (of 128 speed steps) is a different notch, so the faster you go the higher the notch you will be in.
See the video below for a demonstration of Traditional Throttle Mode:
Configuration Options
Traditional throttle mode can be selected though and can be selected using Audio_Assist® menu 4.1. Both WOWSteam and WOWDiesel support Traditional Throttle Mode.
(WOWDiesel ONLY): The speed setpoints that the prime mover changes notches are controlled by CV165 through CV172 - where CV165 controls when the locomotive goes into Notch 1 and CV172 controls what speed step the locomotive goes into Notch 8.
(WOWSteam ONLY): To adjust the volume of the Chuff while in Traditional Throttle Mode, you need to change the volume level for the sound type "Chuff." This can be done easily through Audio Assist®. Note that making this change to the Chuff volume type will affect the maximum volume that the Chuff can reach when in Prototype Throttle Mode.
Other Traditional Throttle Mode Features
When you select Traditional Throttle Mode, the momentum values are set to the "Switching Momentum" values stored in the decoder as part of the Momentum Modes feature. The Switching Momentum values are typically low momentum values which disregard realism in favor of a "snappy" and "slot-car-like" operating experience which closely ties the speed of the locomotive to the speed on your handheld throttle. While it is still possible to slow down your locomotive using the Train Brake, it is not a requirement with Traditional Throttle Mode. That said, you can use the Momentum Modes feature to switch back to Mainline Momentum in case you only want to have the notching or chuff intensity be constant but the momentum be realistic.
Manual Notching Throttle Mode (WOWDiesel)
WOWSound from TCS is the original "Full Throttle" diesel decoder. We call it "Manual Notching" but the feature is essentially the same. Manual notching is available on every WOWSound diesel decoder ever made, beginning with Version 1 released back in January of 2015, as part of our overall Proto Notch™ experience.
What is Manual Notching?
Manual Notching allows you to independently adjust the prime mover sound or "notch sound", and separately control the speed of the locomotive. Real life locomotives can be set in notch eight but operating at slow speed because of a heavy train and steep grade. Your TCS decoder by default is configured to Prototype Throttle Mode, giving you the correct load-based sound!
Manual Notching is for users who like to run prototypically without letting the decoder have all the fun of Auto Notching. If you'd like to move notch sounds manually, there are two modes: Semi-Manual Notching and Full-Manual Notching.
The main advantage of TCS' Manual Notching, when compared to many other implementations by other manufactures, is that with a WOWSound decoder you can completely separate the locomotive physical speed and RPM while still retaining complete control of both simultaneously. Additionally, entering and exiting manual notching is simple. Continue reading to learn more.
How do I use Manual Notching?
Using the throttle, you set the desired speed of the loco, and by using the Manual Notch up (default button 10) and Manual Notch down (default button 11) you can change the notch sound to the desired notch. Yes it is that simple! The notch sound you manually select locks in and overrides the current throttle mode's selected notch setting.
Semi-Manual Notching
The manual notch buttons are always active regardless of which Throttle Mode is selected; however, when not in the Manual Notching Throttle Mode, manual changes are overridden when a speed change is made. For example if you are in Traditional Throttle Mode and running down a hill you may want to manually notch down, and then when you reach the bottom of the hill, changing the speed will revert the notch back to what it was before going down the hill. (Note that this is the behaviour you would observe when in Prototype Throttle Mode.) While in manual notch mode speed changes do not override the manual notch setting.
With semi-manual notching active, when you change the throttle the decoder automatically takes back control and sets the appropriate notch sound as determined by the active throttle mode. Ergo, the notching will return from manual to autpomatic if you change the speed of the locomotive.
Full Manual Notching
With the Manual Notching Throttle Mode active, you can manually select the notch by pressing the notch up or notch down buttons. Meanwhile you can still control the speed as your normally would without affecting the active notch setting. This gives full control of both the speed and notch to you simultaneously and completely independently! With full manual notching active, the decoder does not take back over the selected notch when you change the throttle. You remain in full control of the selected notch at all times. To override the decoder's selected notch setting simply use the Manual Notch up and down buttons at any time. Manual Notching overrides the automatically selected notch sound. You can notch up before you even move the locomotive!
Can I remap the Manual Notching buttons?
Yes. By default, TCS "Manual Notch Up" is button ten, and "Manual Notch Down" is button eleven; however, if Manual Notching is something that you would like to use often then we recommend you re-map the

Dual Purpose Cutting Head
This coke-cutting procedure involves the use of a combination coke-cutting/drilling tool made by Pacific Pumps (Dresser Industries), as shown in Figure 2-12. This cutting head is currently in use in a large minority of U.S. cokers. The Worthington dual-purpose cutting head was found to be impractical and is no longer available.
The head permits switching from the pilot bit mode to the cutting mode, using the same head. Switching is a five-minute manual operation.
The tool design has jet nozzles that create a tighter stream of water that maintains its energy at the wall of large-diameter coke drums. The nozzle concentrates the power from the jet pump and provides a sharper hydraulic jet of water to more effectively cut the coke.
One operator reported that the combination head reduced the cutting time (time from completion of pilot drilling to the time the jet pump is stopped) from 2.5 hours using another bit design, to about 1.6 hours with the combination bit.
When cutting soft, fuel-grade coke or shot coke from a large-diameter drum, and utilizing a high-discharge-pressure jet pump, the main impediment to rapid coke cutting is coke cave-in which can bind the drill stem.
The following drilling and cutting procedure is designed to be used with the combination cutting head to help reduce the cave-in problem and increase the speed with which the coke can be removed from the drum:
- Drill the pilot hole while gradually lowering the stem at a rate of approximately 10 ft/min. A maximum drill stem rotational speed of 15-20 rpm is recommended to create a pilot hole diameter of about 2.5 ft at the top of the coke bed. Do not cut coke out of the bottom cone.
- After the pilot hole is completed, stop the drilling unit and oil the pneumatic motor.
- Withdraw the drill stem with the flow of cutting water stopped. Remember that the top 5-10 ft of the coke bed is like sand and can easily collapse, jamming the drill stem. This can be prevented by careful removal of the stem and by avoiding undercutting the soft coke layer. Undercutting can be prevented by carefully enlarging the pilot hole by running the cutting head down again.
- Switch the combination cutting tool from the pilot drilling mode to the cutting mode by applying air pressure to a fitting on the combination tool and observing the position of a 1 -in. steel pin (refer to manufacturer's instructions).
- Open a 3- or 4-in. water connection located under the drum-relief valve to allow quench water to suppress the evolution of steam from the top head of the drum. This will improve the operator's visibility when the tool mode is switched.
- Adjust the drill stem motor to rotate at a rate of 8-10 rpm and begin coke cutting.
- As cutting progresses, observe the size of the coke lumps leaving the drum. Control the vertical speed of the drill stem so that the lumps leaving the drum are about fist size. Increase the vertical speed if the lump size increases, and decrease the speed if the lumps get smaller. Controlling the lump size is important to avoid cave-ins that result in bottom-head plugging.
- The first pass of the cutting head should enlarge the pilot hole to 4-5 ft in diameter at the top of the coke bed (with water flowing on both the downstroke and the upstroke).
- Make two more passes with the drill stem turning at 8-10 rpm. After the third pass, the level of coke in the drum will be reduced by about 20 ft. This means that, to save time, the cutting head should not be raised to the original starting point after each pass. Gauging the residual level of coke in the drum can be done by observing the evolution of steam from the top head. If no coke is being cut and no coke is falling through the drum, steam evolution will increase. Experienced operators can also note the sound of water striking the metal sides of the drum, indicating coke has been removed from that level in the drum.
- The fourth and subsequent passes should be made with the drill stem readjusted to rotate at 6-8 rpm. Reducing the head rotation speed keeps the tangential velocity of the water jet at the coke interface at a relatively constant value as the coke wall approaches the drum wall.
- In a typical operation, four to six more passes will be required to fully remove the remaining coke. Each of these remaining passes will take about 10-12 minutes.
- After the last cutting pass, a tough ring of coke, several feet high and several feet above the bottom of the drum, will adhere to the drum wall. This can be removed using the high-energy jets of the combination tool. This generally takes only a few minutes. With other head types, this layer has to be removed by grinding.
The procedure depends on a good source of clarified water supply to the cutting head and frequent inspection of the cutting nozzles for wear.
The procedure will reduce cutting time for large coke drums making primarily fuel-grade coke. Field experience indicates that the procedure can decoke drums containing up to 1,000 tons of green coke in about two hours.

"The river is constantly turning and bending and you never know where it's going to go and where you'll wind up. Following the bend in the river and staying on your own path means that you are on the right track. Don't let anyone deter you from that."
~ Eartha Kitt
The relation between the river and the mountain is pretty symbolic. The river with all its gushing waters symbolizes motion – the dynamism of life. And the mountains with their huge, unwavering existence are the symbol of obstacles that we face in life. The river makes its way through the mountains – sometimes it is able to break through the solid rocks and sometimes it bends its path – but never stops until it meets the sea. Together the river and the mountain teach us the biggest lesson of life – keep going until you reach your goal; until the purpose of life is served. There will be problem, there will be obstruction, there will be barrier – but you should learn to make your way through it and move on.

Serbian troches
from Wikipedia, the free encyclopedia
The Serbian troche is a trochaic fivelifter without a caesura and rhyming, whereby individual troches can also be replaced by spondes. The designation goes back to the catalectic ten-syllable of the Serbian folk poetry, in particular the Serbian heroic songs, and was introduced into German poetry through their reproduction with Trochaic five-pointers by Johann Gottfried Herder. In the following examples can be found mainly in (historical) ballads by Gottfried August Bürger, Johann Wolfgang Goethe ( lament of the noble women of Asan Aga, The Bride of Corinth ), Friedrich Rückert, August von Platen ( Abbasids ), Emanuel Geibel, Conrad Ferdinand Meyer, Gottfried Keller, Detlev von Liliencron, Agnes Miegel ( Duke Samo ), Josef Weinträger ( The Trochäus ) and Max Mell ( The Fair Weather Witch ).
As an example from Platen's verse epic The Abbasids the first verses:
A thousand tents were pitched
through the field at the gates of Baghdad,
To celebrate the festival of the new year:
On the throne sat the great Harun
As caliph with all signs of dignity,
ring in the circle his crown officials [...]

Update[symbol] tells Mathematica that hidden changes have been made which could affect values associated with a symbol.
Update[ ] specifies that the value of any symbol could be affected.
Update manipulates internal optimization features of Mathematica. It should not need to be called except under special circumstances that rarely occur in practice.
One special circumstance is that changes in the value of one symbol can affect the value of another symbol by changing the outcome of Condition tests. In such cases, you may need to use Update on the symbol you think may be affected.
Using Update will never give you incorrect results, although it will slow down the operation of the system.

Q: I need help identifying a bird I have at my feeder. It looks like a cardinal except for the head, which appears to be devoid of feathers! It has normal red body feathers and a head with no crest.
A: You have a male cardinal whose feathers have dropped off. This is the subject of lengthy discussion among birders but the consensus is that it can be caused by mites, heat or nutritional difficulties. The folks at Hilton Pond Center in South Carolina have observed several birds with this condition (which they call "lizard-head"), including one who was bald one year but fully recovered the next.

This from Wiki. Note 'revealed' in the second paragraph:
Willem-Alexander is an avid pilot and has said that if he had not been a royal, he would have liked to be an airline pilot so he could fly big planes such as the Boeing 747. In 1989, Willem-Alexander flew as a volunteer for the African Medical Research and Education Foundation (AMREF) in Kenya, and in 1991 he spent a month flying for the Kenya Wildlife Service. During the reign of his mother, he regularly flew the Dutch royal airplane on trips.
In May 2017, Willem-Alexander revealed that he had served as a co-pilot on KLM flights for 21 years, flying KLM Cityhopper's Fokker 70s twice a month, even after his ascension to the throne. With KLM's phased retirement of the Fokker 70, he began training to fly Boeing 737s. Willem-Alexander was rarely recognized while in the KLM uniform and wearing the KLM cap, though a few passengers had recognized his voice, even though he never gave his name and only welcomed passengers on behalf of the captain and crew.[

Target up to one natural or manufactured weapon per 3 caster levels
Duration 10 minutes/level
The target weapons and any ammunition they fire make no sound as part of their normal functions as a weapon. For instance, a firearm's firing would not make an explosive sound, but if you cast this spell on a creature's bite attack, it would not prevent it from vocalizing from its mouth. The first time a creature is struck by a weapon affected by this spell, it must succeed at a Will save (SR applies to this effect) or it becomes unable to make noise louder than a whisper (Perception DC 10 to hear) whether vocally or by other means for the duration of the effect. Because the creature can still whisper, this doesn't interfere with verbal spell components. Whether it succeeds or fails its saving throw, the creature is immune to further effects from this casting of quieting weapons.

"Witlings Defame Her": William Gaston and "The Old North State"
State Supreme Court Justice William Joseph Gaston of New Bern penned the song's patriotic lyrics in the 1830s, when North Carolina was lagging economically behind its neighbors and masses of people were moving away. A dedicated public servant and advocate for internal improvements, Gaston sought to defend North Carolina against accusations of being backward.
When court was in session in Raleigh, Gaston stayed at the home of Mrs. James F. Taylor. One day after a couple of women in the household returned from a concert by a group of visiting Swiss bellringers, they began to sing and play one of the concert tunes on the piano. Gaston became inspired. At his office on Hargett Street, he wrote several verses of the now-familiar song, adapting it to the melody he had just heard. A chorus of 50 young women first performed the song at the Whig state convention in Raleigh in October 1840.
R. Culver set Gaston's poem to music in 1844, but the arrangement composed in 1926 by Mrs. E. E. Randolph in Raleigh is the version familiar to North Carolinians today.
For more on Gaston and the state song, check out the Old North State Fact Book from North Carolina Historical Publications.

Should you worry about your state's pass average?
In my opinion, law students waste too much time and energy worrying about their state's bar passage rates.
Your state's overall pass average for a particular exam is not the biggest predictor of individual success. Instead the factors which are actually within the control of the student tend to prove to be the more accurate predictors of success. In other words, the amount of time spent in preparation, the amount of practice testing done by the student, etc. are more significant predictors of success. So are things like whether the student studies full-time versus trying to hold down a job or handle other outside distractions.
In my experience, students who put in the necessary hours and who use their study time effectively tend to pass the exam every time regardless of the overall state pass average. So rather than worrying about factors that are beyond your control, why not focus your energy on the things you can control and make the success factors work in your favor.
