Why does glass bending machine use electric cartridge heater?
As we all know, the working environment of glass bending machine is embedded dry burning working environment, so this kind of heating method can only be well heated by electric cartridge heater. Then what factors effect the quality of electric cartridge heater?
In industrial production, The electric cartridge heater of 3D glass bending machine belongs to high surface load electric cartridge heater, so the high surface load of electric cartridge heater directly determines the material selection of other tubes. The imported high temperature magnesia powder is used for internal insulation to increase its insulation performance. At the same time, the lead wire is made of nickel stranded wire with ceramic beads, high temperature resistant lead and wiring mode It is better to use the inner lead because the temperature of the outer lead is not high and the surface load is low.
cartridge heater for 3D Glass bending
What are the processing procedures of electric cartridge heater? The processing procedure of the electric cartridge heater is as follows: the electric cartridge heater refers to the metal tubular single head heating pipe, and then the spring electric heating wire is put into the metal protective sleeve, and the gap part is evenly filled with modified oxide powder with good thermal conductivity and insulation. After the pipe is shrunk by the pipe shrinking machine, the electric heating wire is insulated from the air, and the central position does not deviate and touch the pipe wall Annealing, bending, welding fasteners and other processes.
The electric cartridge heater for 3D glass bending machine can meet the service temperature of 3D glass bending machine, and the heating pipe of 3D glass bending machine can be heated to 950 ℃, and the temperature of heating mold is uniform and stable, and the temperature difference is small. The thermal leakage current of single head electric heating tube is less than or equal to 1mA, and we know that the service life of electric cartridge heater is relatively long.
If you want to make the electric cartridge heatere of 3D glass hot bending machine use longer, you can only work on the material:
The electric cartridge heater of 3D glass bending machine is made of heating wire imported from Germany, high-temperature magnesium oxide powder with insulation and heat conduction customized from Germany, and seamless 800 pipe imported from Japan, with a service life of 9600h.
Moreover, the lead-out wires of the electric heating tube of the 3D glass bending machine are all of the quality leads: pure nickel high-temperature resistant wire imported from Germany.

I wrote a demo program in C++ that includes a Perlin noise texture class, which I hope provides a decent example of C++ code for Perlin noise. You can find the demo at _URL_
If I've made any grave errors or you just want to comment, feel free to email me.
When I talk about a noise function, I mean a function that takes a coordinate in some space and maps it to a real number between -1 and 1. Note that you can make noise functions for any arbitrary dimension. The noise functions above are 2-dimensional, but you can graph a 1-dimensional noise function just like you would graph any old function of one variable, or consider noise functions returning a real number for every point in a 3D space.
These images were all created using nothing but Perlin noise:
Let's look at the 2D case, where we have the function
noise2d(x, y) = z,with x, y, and z all real (floating-point) numbers. We'll define the noise function on a regular grid, where grid points are defined for each whole number, and any number with a fractional part (i.e. 3.14) lies between grid points. Consider finding the value of noise2d(x, y), with x and y both not whole numbers -- that is, the point (x, y) lies somewhere in the middle of a square in our grid. The first thing we do is look at the gridpoints surrounding (x, y). In the 2D plane, we have 4 of them, which we will call (x0, y0), (x0, y1), (x1, y0), and (x1, y1).
Now we need a function
g(xgrid, ygrid) = (gx, gy)which takes each grid point and assigns it a pseudorandom gradient of length 1 in R2 ('gradient' is just the name for an ordered pair or vector that we think of as pointing in a particular direction). By pseudorandom, we mean that g has the appearance of randomness, but with the important consideration that it always returns the same gradient for the same grid point, every time it's calculated. It's also important that every direction has an equal chance of being picked.
Also, for each grid point, we generate a vector going from the grid point to (x, y), which is easily calculated by subtracting the grid point from (x, y).
Now we have enough to start calculating the value of the noise function at (x, y). What we'll do is calculate the influence of each pseudorandom gradient on the final output, and generate our output as a weighted average of those influences.
First of all, the influence of each gradient can be calculated by performing a dot product of the gradient and the vector going from its associated grid point to (x, y). A refresher on the dot product -- remember, it's just the sum of the products of all the components of two vectors, as in
(a, b) · (c, d) = ac + bd.Since I'm really tired of writing subscripts, we'll just refer to these 4 values as s, t, u, and v, where
s = g(x0, y0) · ((x, y) - (x0, y0)),So here's a 3D-ish picture of some influences s, t, u, and v coming out of the R2 plane (note that these probably wouldn't be the actual values generated by the dot products of the vectors pictured above).
t = g(x1, y0) · ((x, y) - (x1, y0)),
u = g(x0, y1) · ((x, y) - (x0, y1)),
v = g(x1, y1) · ((x, y) - (x1, y1)).
Geometrically, the dot product is proportional to the cosine of the angle between two vectors, though its unclear to me if that geometrical interpretation helps one visualize what's going on. The important thing to know at this point is that we have four numbers, s, t, u, and v which are uniquely determined by (x, y) and the pseudorandom gradient function g. Now we need a way to combine them to get noise2d(x, y), and as I suggested before, some sort of average will do the trick.
I'm going to state the obvious here and say that if we want to take an average of four numbers, what we can actually do is this:
We're not taking a plain vanilla-flavored average here, but instead, a weighted average. That is, the value of the noise function should be influenced more by s than t when x is closer to x0 than x1 (as is the case in the pictures above). In fact, it ends up being nice to arrange things so that x and y values behave as if they are slightly closer to one grid point or the other than they actually are because that has a smoothing effect on the final output. I know that sounds really silly, but noise without this property looks really stupid. In fact, it sounds so silly that I'm going to write it again: we're going to want the input point to behave as if its closer to one grid point or another than it actually is.
This is where we introduce the concept of the ease curve. The function 3p² - 2p³ generates a nice S-shaped curve that has a few characteristics that are good for our purposes.
What the ease curve does is to exaggerate the proximity its input to zero or one. For inputs that are sort of close to zero, it outputs a number really close to zero. For inputs close to one, it outputs a number really close to one. And when the input is exactly one half, it outputs exactly one half. Also, it's symmetrical in the sense that it exaggerates to the same degree on both sides of p = ½. So if we can treat one grid point as the zero value, and the other as the one value, the ease curve has the exact smoothing effect that just we said we wanted.
Ok, I've droned on long enough, it's calculation time: first, we take the value of the ease curve at x - x0 to get a weight Sx. Then we can find the weighted average of s and t by constructing a linear function that maps 0 to s and 1 to t, and evaluating it at our x dimension weight Sx. We'll call this average a. We'll do the same for u and v, and call the result b.
The above figures should satisfy you that no matter where x happens to fall in the grid, the final averages will always be between s and t, and u and v, respectively. Mathematically, this is all simple to calculate:
Sx = 3(x - x0)² - 2(x - x0)³Now we find our y dimension weight, Sy, by evaluating the ease curve at y - y0, and finally we take a weighted sum of a and b to get our final output value z.
a = s + Sx(t - s)
b = u + Sx(v - u)
And there you have it. So all you have to do is call the noise function for every pixel you want to color, and you're done. Probably.
An interesting consequence of all of this is that the noise function becomes zero when x and y are both whole numbers. This is because the vector (x, y) - (x0, y0) will be the zero vector. Then the dot product of that vector and g(x0, y0)will evaluate to zero, and the weights for the averages will also always be zero, so that the zero dot product will influence the final answer 100%. The funny thing is that looking at the noise function, you would never guess that it ends up being zero at regular intervals.
The neat thing about noise is that it's locally variable, but globally flat -- so if we zoom out to a large degree, it will just look like a uniform value (zero in fact). So, we don't care if the noise function starts to repeat after large intervals, because once you're zoomed out far enough to see the repeat, it all looks totally flat anyways.
So now we should feel justified in doing a little trick with modulus. Say we're doing noise in 3D, and we want to find the gradient for some grid point (i, j, k). Let's precompute a permutation table P, that maps every integer from 0 to 255 to another integer in the same range (possibly even the same number). Also, let's precompute a table of 256 pseudorandom gradients and put it in G, so that G[n] is some 3-element gradient.
g(i, j, k) = G[ ( i + P[ (j + P[k]) mod 256 ] ) mod 256 ]But on a computer, modulus with 256 is the same thing as a bitwise and with 255, which is a very fast operation to perform. Now we've reduced the problem of a possibly involved function call into nothing but some table lookups and bitwise operations. Granted, the gradients repeat every 256 units in each dimenstion, but as demonstrated, it doesn't matter.
This speedup is also mentioned on Perlin's web page, and is actually used in his original implementation.

Proof of proposition 4
The proof is similar to the proof of proposition 2.
Conditional logistic regression
If the \(\mathrm{N}\) subjects are assigned to \(\mathrm{S}\) strata according to covariates such as gender and age and there are \({N}_{k}\) control subjects for \(k=1, 2,\dots , \mathrm{S}\), then the conditional likelihood under a logistic regression model is given by
$${L}_{C}\left({\beta }_{1}\right)= \prod_{k=1}^{S}\frac{\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{0:\mathrm{k}}}{\mathrm{t}}_{0\mathrm{j}:\mathrm{k }}{\mathrm{x}}_{0\mathrm{j}:\mathrm{k}}\right)}{\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{0:\mathrm{k}}}{\mathrm{t}}_{0\mathrm{j}:\mathrm{k }}{\mathrm{x}}_{0\mathrm{j}:\mathrm{k}}\right)+\sum_{i=1}^{{\mathrm{N}}_{k}}\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{\mathrm{i}:\mathrm{k}}}{\mathrm{t}}_{\mathrm{ij}:\mathrm{k }}{\mathrm{x}}_{\mathrm{ij}:\mathrm{k}}\right)}$$
(5)
(Breslow and Day 1980) [8]. Here, \(0:k\) and \(0j:k\) refer to the case in stratum \(k\) and the case in stratum \(k\) with job index \(j\); and \(i:k\) and \(ij:k\) refer to the control subject number \(i\) in stratum \(k\) and the control subject number \(i\) in stratum \(k\) with job index \(j\).
In one situation, the conditional logistic likelihood is the same as the conditional Poisson likelihood with \({Y}_{i:k}\sim Poisson\left(\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{\mathrm{i}:\mathrm{k}}}{\mathrm{t}}_{\mathrm{ij}:\mathrm{k }}{\mathrm{x}}_{\mathrm{ij}:\mathrm{k}}\right)\right)\) for \({i=0, 1, 2,\dots , N}_{k}\) (case and control subjects) for \(k=1, 2,\dots , \mathrm{S}\), with the random variables \({Y}_{i:k}\) are independent for all \(i\) and \(k\). That situation happens when \({y}_{0:k}=1\) and \({y}_{1:k}=\dots ={y}_{{N}_{k}:k}=0\) for all \(k\) (\(k=1, 2,\dots , \mathrm{S}\)).
Notice that for each \(k\) (\(k=1, 2,\dots , \mathrm{S}\))
$$\left[{Y}_{0:k}|{Y}_{0:k}+{Y}_{1:k}+\dots +{Y}_{{N}_{k}:k}=M\right]\sim \mathrm{Binomial}\left(M, \frac{\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{0:\mathrm{k}}}{\mathrm{t}}_{0\mathrm{j}:\mathrm{k }}{\mathrm{x}}_{0\mathrm{j}:\mathrm{k}}\right)}{\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{0:\mathrm{k}}}{\mathrm{t}}_{0\mathrm{j}:\mathrm{k }}{\mathrm{x}}_{0\mathrm{j}:\mathrm{k}}\right)+\sum_{i=1}^{{\mathrm{N}}_{k}}\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{\mathrm{i}:\mathrm{k}}}{\mathrm{t}}_{\mathrm{ij}:\mathrm{k }}{\mathrm{x}}_{\mathrm{ij}:\mathrm{k}}\right)}\right).$$
Therefore,
$$P\left({Y}_{0:k}=1|{Y}_{0:k}+{Y}_{1:k}+\dots +{Y}_{{N}_{k}:k}=1\right)$$
$$=\frac{\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{0:\mathrm{k}}}{\mathrm{t}}_{0\mathrm{j}:\mathrm{k }}{\mathrm{x}}_{0\mathrm{j}:\mathrm{k}}\right)}{\mathrm{exp}\left({\beta }_{1} \sum_{j=1}^{{J}_{0:\mathrm{k}}}{\mathrm{t}}_{0\mathrm{j}:\mathrm{k }}{\mathrm{x}}_{0\mathrm{j}:\mathrm{k}}\right)+\sum_{i=1}^{{\mathrm{N}}_{k

Xylophis captaini was probably originally an inhabitant of the rich rainforests of the western foothills of the Western Ghats mountains. It is still found in remaining patches of rainforest here, but it is mostly encountered in the plantations and gardens that have largely replaced forest in this region.
X. captaini hides (and perhaps feeds) in the soil and was only described in 2007, so little is known of its ecology. During the daytime the snake is generally found only by digging and turning over surface soil and leaf litter in rich, shady and moist habitats.
As with many other burrowing snakes, the scales of X. captaini are iridescent, which seems to be a by-product of having scales with minute ridges adapted to easily shed moist soil.
The details of its diet are not completely known, but includes at least small earthworms.
No reports of predation are known, but predators probably include other burrowing vertebrates.

Find a relationship between x and y such that (x,y) is equidistant from the two points.
(3,-2) and (-7, 1)
To solve this equation:
- Square both sides of the equation
- Use subtraction to get both of the y terms on one side and both of the x terms on the other
- Expand the squares and simplify
- Solve for y in terms of x
Check your answer against (-2, -0.5) -- the exact values, obtained by the midpoint formula --by plugging them into the resulting function.
You are correct. There is an alternative, simpler and easier way to do this btw:
1. Using midpoint formula, find the point that is equidistant between these two points is:
2. Find the slope of the two given points. (-3/10)
3. Take the negative reciprocal of the slope (10/3).
4. Plug in point-slope form (Use the negative reciprocal slope and the point we got from midpoint formula):
y - y1 = m(x - x1)
There, you got yourself the equation for a line that is perpendicular to the midpoint.
You could have used the construction of the perpendicular bisector to verify your answer. Working it two ways and getting the same answer is a great confidence builder. Too bad Chop Suey did it for you. You missed a great opportunity to explore and to learn. Don't let the next opportunity get by you.

Maintaining ACH Network Quality
Support NACHA Operating Rules Compliance by Reporting Violations
By requiring participants to comply with the NACHA Operating Rules, NACHA maintains a high-quality, secure ACH Network. It's essential that non-compliance issues be resolved fairly and efficiently in order to provide financial institutions and end-users with a reliable Network. To that end, NACHA employs the National System of Fines as an enforcement mechanism for the Rules, allowing Depository Financial Institutions to review, evaluate and correct the circumstances surrounding any possible Rule violation.
NACHA's Members support Rules compliance by reporting those violations, using the procedures below.
The National System of Fines
The National System of Fines provides the structure for evaluating possible Rules violations. Through a formal system of warnings and fines, it corrects infractions and helps ACH Network participants to remain within the Rules' boundaries.
Instructions for Filing
If your organization or financial institution discovers a potential infraction, it should submit the issue to NACHA through a Report of Possible ACH Rules Violation. As the complainant, your organization must be a Participating DFI or ACH Operator that is party to the transaction in question. If that's not the case, your financial institution can file on your behalf.
To submit that report, you'll need the following information:
- Your contact and organization information, as well as your participant status (ODFI, RDFI, ACH Operator or other).
- A clear description of the alleged violation, including the sequence of events and consequences of the violation.
- The specific Rules provision in alleged to be violated.
- Transaction type information:
- SEC Code
- Transaction Code
- Settlement Date
- Dollar Amount
- Trace Number
- Account Number
- Date of Alleged Rules Violation
- Copies of all relevant documents with your report, such as Company/Batch Header Records, Entry Detail Records or Addenda Records
- Any written communication between the complainant and party in alleged violation of the Rules.
- Signature of an authorized representative of the complainant.
Your report must be submitted to NACHA within 90 days of the alleged Rules violation occurrence. If you feel that more than one Participating DFI has committed the same Rules violation, you must submit a separate report for each case.
Each Report of Possible ACH Rules Violation should be either submitted online, or downloaded (form available in the right-hand side bar), completed and sent to NACHA, Attn: Compliance Department by U.S. Mail (2550 Wasser Terrace, Suite 400, Herndon, VA 20171).

Temperature is usually measure in degrees Celsius (ºC) OR degrees Fahrenheit (ºF). These temperature scales are based on the point at which water boils and freezes. Make your own simple thermometer and measure the temperature.
Steps to be taken
1. Ask an adult to drill a hole in the bottle's cap. Assemble the thermometer, making sure that the water comes part away up the straw when you fix o the cap. Leave the water to settle for an hour then mark the water level on the scale. 2. Stand the thermometer in a bowl of ice cold water and a bowl of very hot water. See how the water level changes. 3. Ask an adult to help you fix a thermometer in a shady, dry place outdoors. Keep a record of the daily temperature for a month.

and the Greek lowercase beta (U+03B2, β).
 - 227dec (E3hex) is the Greek lowercase pi (U+03C0, π), but early fonts such as Terminal use a variant of pi that is ambiguous in case, and therefore can be used for the Greek capital pi (U+03A0, Π) or the n-ary product sign (U+220F, ∏).
 - 228dec (E4hex) is both the n-ary summation sign (U+2211, ∑) and the Greek uppercase sigma (U+03A3, Σ).
 - 230dec (E6hex) is both the micro sign (U+00B5, µ) and the Greek lowercase mu (U+03BC, μ).
 - 234dec (EAhex) is both the ohm sign (U+2126, Ω) and the Greek uppercase omega (U+03A9, Ω). (Unicode considers the ohm sign to be equivalent to uppercase omega, and suggests that the latter be used in both contexts.[5]).
 - 235dec (EBhex) is the Greek lowercase delta (U+03B4, δ), but it has also been used as a surrogate for the Icelandic lowercase eth (U+00F0, ð) and the partial derivative sign (U+2202, ∂).
 - 237dec (EDhex) is supposed to be used as Greek lowercase phi, but is mainly used as the empty set sign (U+2205, \varnothing) and was also used as the Greek phi symbol in italics (U+03D5, \phi\,\!) to name angles, diameter sign (U+2300, \varnothing), and as a surrogate for the Latin lowercase O with stroke (U+00F8, ø).
 - 238dec (EEhex) is both the Greek lowercase epsilon (U+03B5, ε) and the element-of sign (U+2208, ∈). Later it was often used for the euro sign (U+20AC, €).
Entry on keyboards
In DOS and Windows, most characters from the currently active DOS code page can be inserted by holding down the Alt key and entering the character's three-digit decimal code on the numpad. This technique is called Windows Alt keycodes. One can find out which DOS code page is currently active by issuing the DOS command mode con or chcp.
Difference from ASCII
CP437 is based on ASCII, with the following modifications:
 - Codes from the C0 control range (00hex to 1Fhex) and ASCII DEL (7Fhex) can assume their original function as control characters, but also function as graphic symbols when displayed in text mode from the screen buffer. For example, DEL and most of the C0 control codes are displayed graphically in a screen editor like MS-DOS Editor or when written to the screen via the DOS type command. The graphics include smiling faces, card suits, and musical notes. Code 127dec (7Fhex), DEL, shows as a "house". This behavior is not specific to CP437, but shared by all DOS code pages and so-called Windows OEM code pages, which generally resemble CP437.
 - The high-bit range, 128dec to 255dec (80hex to FFhex), is mapped to various symbols: a few European characters (accented Latin letters, etc.) in no particular order and not sufficient for representation of most Western European languages; box drawing characters; mathematical symbols; and a few Greek letters commonly used in mathematics and physics.
The repertoire of CP437 was taken from the character set of Wang word-processing machines, according to Bill Gates in an interview with Gates and Paul Allen that appeared in the 2 October 1995 edition of Fortune Magazine:
"... We were also fascinated by dedicated word processors from Wang, because we believed that general-purpose machines could do that just as well. That's why, when it came time to design the keyboard for the IBM PC, we put the funny Wang character set into the machine—you know, smiley faces and boxes and triangles and stuff. We were thinking we'd like to do a clone of Wang word-processing software someday."
The selection of graphic characters, often called bizarre,[citation needed] has some internal logic:
 - Table rows 0 and 1, codes 0dec to 31dec (00hex to 1Fhex), are assorted dingbats (complementary and decorative characters). The isolated character 127dec (7Fhex) also belongs to this group.
 - Table rows 2 to 7 (except character 127dec, 7Fhex), codes 32dec to 126dec (20hex to 7Ehex), are the standard ASCII printable characters.
 - Table rows 8dec to 10dec (8hex to Ahex), codes 128dec to 175dec (80hex to AFhex), are a selection of international text characters.
 - Table rows 11dec to 13dec (Bhex to Dhex), codes 176dec to 223dec (B0hex to DFhex), are box drawing and block characters. This block is arranged so that characters 192dec to 223dec (C0hex to DFhex) of the rows 12dec and 13dec (Chex and Dhex) have all right arms (except 217dec, D9hex) or right filled areas (except 221dec, DDhex), and this is due to the following technical reason:[6] the original IBM PC MDA display adapter stored the CP437 character glyphs as bitmaps eight pixels wide, but for visual enhancement displayed them every nine pixels on screen (eight plus an additional gap). Thus characters with connections at their right edge had to duplicate their eighth pixels to avoid visual interruptions in the designs built up with them. This pixel extension is done by special hardware circuitry, and only this character subset is affected.
 - Table rows 14dec and 15dec (Ehex and Fhex), codes 224dec to 255dec (E0hex to FFhex) are devoted to mathematical symbols, where the first twelve are a selection of Greek letters commonly used in physics. Characters 244dec (F4hex) and 245dec (F5hex) are the upper and lower portion of an italic long S, the symbol used as the integral sign (), and they can be extended with the character 179dec (B3hex), the vertical line of the box drawing block. Characters 249dec (F9hex) and 250dec (FAhex) are almost indistinguishable: the first is slightly larger than the second, which resembles the typographic middle dot (·). The character 255 (FFhex) is merely blank, and acts as a kind of non-breaking space in order to arrange math formulae.
Internationalization
CP437 has a series of international characters, mainly values 128dec to 175dec (80hex to AFhex). However, it lacks many characters important to several Western languages:
 - Spanish (Á, Í, Ó, Ú), French (À, Â, È, Ê, Ë, Ì, Î, Ï, Ô, Œ, œ, Ù, Û), and Portuguese (Ã, ã, Õ, õ).
 - German sharp S (ß) shares its code point with the beta symbol (β).
 - Scandinavian lacks Ø and ø. Character number 237dec (EDhex), the empty set symbol, could be used as a surrogate, but its spacing is awkward for display within a word. To compensate, the Norwegian and Danish code pages (CP865 and CP861), replaced cent (¢) with ø, and yen (¥) with Ø.
 - Most Greek alphabet symbols. (They were included in the Greek-language code pages CP737 and CP869.)
Along with the cent (¢), pound sterling (£) and yen/yuan (¥) currency symbols, it has a couple of European currency symbols: the florin (ƒ, Netherlands) and the peseta (₧, Spain). The presence of the last is unusual, since the Spanish peseta was never an internationally relevant currency, and also never had a symbol of its own; it was simply abbreviated as "Pt", "Pta", "Pts", or "Ptas". Spanish models of the IBM electric typewriter, however, also had a single position devoted to it.
Later MS-DOS character sets, such as CP850 (DOS Latin-1), CP852 (DOS Central-European) and CP737 (DOS Greek), filled the gaps for international use with some compatibility with CP437 by retaining the single and double box-drawing characters, while discarding the mixed ones (e.g. horizontal double/vertical single). All CP437 characters have similar glyphs in Unicode and in Microsoft's WGL4 character set, and therefore are available in most fonts in Microsoft Windows, and also in

History of the Age of Pericles of Ancient Greece
Experience the History of the Age of Pericles in Ancient Greece with WisdomMaps: The Future of the Past!
Our digital history of the Age of Pericles of ancient Greece (495 – 429 BCE) refers to the life and times of a Greek leader who emerged during the Golden Age of Athens. His was a powerful voice in Athenian politics, particularly when it was needed most during the war with Persia and the Peloponnesian War with Sparta. He was deemed by the historian Thucydides to be "the first citizen of Athens". This was in large part on account of his efforts in spearheading the Delian League into an Athenian empire and leading his countrymen through the first two years of the Peloponnesian War.
Pericles championed democracy to the point of being seen as a populist. As such, he vigorously promoted the arts, and his efforts enabled Athens to become the cultural and intellectual center of the ancient world. This included the restoration of the crumbling ruins of the Parthenon and its surrounding buildings atop the Acropolis. This project beautified and protected the city and showcased its glory, while giving work to Athenians. Pericles fell victim to the Plague of Athens in 429 BC, which weakened Athens and led to its defeat during the long Peloponnesian War.

What is a Mechanism?
A mechanism is a mechanical device used to transfer or transform motion, force, or energy. Traditional rigid-body mechanisms consist of rigid links connected at movable joints. Whatever machines you see in your day to day life has some underlying mechanisms that govern its motion to produce the desired output. For example A NUT CRACKER works on the principle of MECHANICAL ADVANTAGE based on LEVER MECHANISM. This mechanism transfers energy from the input to the output.
Since energy is conserved between the input and output (neglecting friction losses), the output force may be much larger than the input force, but the output displacement is much smaller than the input displacement. As mentioned earlier these mechanisms involve relative motion of rigid bodies often at very high speeds which various problems like Frictional Losses, Non Linear behavior, Non uniform Heat dissipation, etc. Thus modern day scientists are working on mechanisms that more or less achieve the same motion and force transfer with the help of flexible links and linkless joints.
These 2 terms have tremendous significance when its comes to the emerging and exciting field of COMPLIANT MECHANISMS. So lets see what these wonders are and what are they capable of.
A compliant mechanism also transfers or transforms motion, force, or energy. Unlike rigid-link mechanisms, however, compliant mechanisms gain at least some of their mobility from the deflection of flexible members rather than from movable joints only. Basically not all the links of a mechanism need to be flexible for it to be termed as A Compliant System but some important links must be flexible. Fully compliant mechanisms are very unstable and unreliable.
Compliant mechanisms rely upon elastic deformation to perform their function of transmitting and/or transforming motion and force. From an overall perspective that considers performance, manufacturability, economy of material, scalability to micro and Nano sizes, adaptability to smart actuations and embedded sensors, resistance to wear, etc., compliant mechanisms are preferable over rigid body mechanisms.
Large number of compliant mechanisms are constructed of rigid links that are interconnected by Flexure Hinges design to undergo relatively low levels of rotation that traditional Revolute Pair Joints. A relatively less number of compliant mechanisms have compliant links in addition to the Flexure Hinges designed to undergo large deformation.
Currently available design techniques for compliant mechanisms can be grouped broadly into the following three categories based on the methods used as well as the type of mechanisms created using them.
- Flexural pivot-based compliant mechanisms.
- Flexible beam-based compliant mechanisms.
- Fully compliant, elastic continua.
Flexural pivot-based compliant mechanism
Flexural pivot-based designs use narrow sections connecting relatively rigid segments. Thus, compliance is lumped to a few portions of the mechanism. They are usually of monolithic construction. They can be systematically designed either by starting from an available rigid-body linkage or an intuitively conceived linkage. So in this type mainly the joints are flexible which connects rigid links with each other. The biggest problem faced in this type is the force and momentum transfer is very limited. Compliant mechanisms of this type are often restricted to a small range of motion. Their applications are in precision instrumentation and many consumer products.
Flexible beam-based compliant mechanisms
Flexible beam-based compliant designs extend the range of motion because the slender beam-like segments are designed to undergo large deformations. These are not always of monolithic construction, as they may have some rigid segments and kinematic joints. Thus, they are sometimes partially compliant. Unlike in flexural pivotbased designs, the compliance is distributed in flexible beam-based designs.
Design of Compliant Mechanisms
The first step in the design of a compliant mechanism is to establish a kinematicaly functional design that generates the desired output motion when subjected to prescribed input forces. This is called topological synthesis. Although the size and shape of individual elements can be optimized to a certain extent in this stage, local constraints such as stress and buckling constraints cannot be imposed while the topology is being determined. Once a feasible topology is established, performance constraints can be imposed during the following stage in which size and shape optimization are performed.
Topology synthesis—which involves generation of a functional design in the form of a feasible topology starting from input/output force/motion specifications,
Size and shape optimization—to meet performance requirements such as maximum stress, motion amplification or force amplification etc.
General Design procedure involves Systematic methods of design of compliant mechanisms starting from functional specifications. First is deriving the topology of a compliant mechanism given the desired input forces and output displacements. Next, is optimizing the size and shape of various elements of a compliant mechanism in order to satisfy prescribed mechanical or geometric advantage, stress constraints, size constraints etc.
Advantages of Compliant Mechanisms
There are a number of reasons why a compliant mechanism may be considered for use in a particular application.
One advantage of compliant mechanisms is the potential for a dramatic reduction in the total number of parts required to accomplish a specified task.
Some mechanisms may be manufactured from an injection-moldable material and constructed of one piece. For example, consider the fully compliant crimping mechanism shown in the figure below, along with its pseudorigid-body model. Due to symmetry, only half the mechanism is shown. The number of components required for the compliant mechanism are considerably less than for the rigid mechanism. The reduction in part count may simplify manufacturing and reduce manufacturing and assembly time and cost.
It is possible to realize a significant reduction in weight by using a compliant mechanism over their rigidbody counterparts. This may be a significant factor in aerospace and other applications. Compliant mechanisms have also benefited companies by reducing the weight and shipping costs of consumer products.
The reduction in the total number of parts and joints offered by compliant mechanisms is a significant advantage in the fabrication of micro mechanisms. Compliant micro mechanisms may be fabricated using technology and materials similar to those used in the fabrication of integrated circuits.
Disadvantages of Compliant Mechanism
Perhaps the largest challenge is the relative difficulty in analyzing and designing compliant mechanisms. Knowledge of mechanism analysis methods and the deflection of flexible members is required. The combination of the two bodies of knowledge in compliant mechanisms requires not only an understanding of both, but also an understanding of the interactions of the two in a complex system. Since many of the flexible members undergo large deflections, linearized beam equations are no longer valid. Nonlinear equations must be used that account for the geometric nonlinearities caused by large deflections.
I believe the field of Complaint Mechanisms is still in its nascent stage and lots of research and quality work needs to be done regarding the fabrication of proper materials and design of flexible linkages. On the brighter side some of the greatest and brightest minds of the country are working on this field to expand its applications.
Dr. G K Ananthasuresh from IISc Bangalore and Dr. Anupam Saxena from IIT Kanpur are among those few who have contributed quite a lot towards this field. I consider myself lucky to have got the opportunity to meet both of them personally here in NITK when they visited our college last semester for a 2 Day workshop on Kinematics and Mechanism conducted by Dr. Somasekhar Rao sir.

It is an ugly cycle. Shampoo removes buildup, sebum, dirt, but leaves the hair difficult to comb and style. Conditioners cure most of the problems, but tend to produce buildup and attract dirt. Most of the problem is related to the mechanism used to condition hair. Traditional hair conditioners rely on the deposition of molecules like proteins and sugars. Cationic modification of these molecules increase substantivity and neutralize static charge. In some cases, hydrophobic materials such as silicone or natural lipids are used to reduce the drag experienced during combing, or to relipidize the hair. None of these products address the root cause.
Hair needs conditioning because it is damaged. Damage can be physical or chemical, but to produce long lasting conditioning effects the damage must be addressed, not covered over. Perhaps the best way to address the problem and to ensure the integrity of the hair is to protect the integrity of the disulfide bonds present in cystine.
Oxidation of sulfhydryl groups present on opposing cysteine molecules causes the formation of cystine, with its characteristic disulfide bridge. Increased cysteine levels, translate to stronger hair.
The disulfide bonds produce hair's strength and elasticity. Degradation of cystine produces labile, easily extractable proteins in damaged hair. The presence of oxidizers like hydrogen peroxide or other bleaching agents converts cystine to cysteic acid, irreversibly breaking the disulfide bridge.
In plants, cysteine beisynthesis is critical for sulfur assimilation. Two enzymes that exist as a bi-enzyme complex govern the biotransformation of serine to cysteine. Serine is converted to O-acetylserine by acetyltransferase in the presence of acetyl-CoA. O-acetylserine is then condensed with sulfide by O-acetylserine thiol lyase to form cysteine.
Serine is converted by the bi-enzyme complex to cysteine. By providing both substrate and enzyme together, we can allow the formation of cysteine in-situ. By directly nourishing the hair with cysteine, we efficiently provide the hair with the building blocks it needs to maintain its integrity and in turn replenish cystine levels as needed.
Cysteine, state of the amino acid prior to being incorporated into keratin, has an S-H bond. Cystine, is formed when two cysteine molecules aligned on different protein chains oxidized, the molecules are joined by a S-S bond (disulfide).
Lycopene is the pigment that gives tomatoes and many other fruits their red color. A carotene similar to beta-carotene, it is a potent anti-oxidant ten times more efficient than Vitiman E at quenching singlet oxygen. With regard to hair, lycopene's most important property is its solubility. Lipophylic by nature, it can readily penetrate deeply into the hair fiber.
Once in the hair fiber, lycopene can protect cystine from excess oxidation. This particular approach is ideal for use in conjunction with peroxidases, where the peroxidase degrades peroxides and the lycopene decouples any lipid peroxidation.
Maintaining the hairs integral structure, FSS Lycopersicum Bioferment PF an effectively create the perception of long-term conditioning without the use of traditional substantive quats.

Measurement of the atmospheric concentration of nitrogen dioxide (NO 2) pollutant was demonstrated by differential optical absorption spectroscopy (DOAS) using a visible acousto-optic tunable filter. In a traditional spectral scanning DOAS system for atmospheric concentration monitoring, a highly stable light source is required. When the light intensity fluctuates during scanning, the concentration retrieval will be inaccurate. In order to reduce the error due to intensity fluctuations, a modified DOAS system has been developed by introducing a broadband light intensity monitoring channel. Using the measured intensity of the broadband channel as the intensity of the light source, the spectrum can be de-biased and the residual intensity variation will primarily result from atmospheric extinction. In addition, by employing the lock-in detection technique, the background light interference is also removed in the modified DOAS system. The atmospheric NO2 concentration measurement was performed at the campus of City University of Hong Kong, and the results were compared with the concentration reported from a nearby monitoring station in Sham Shui Po, operated by the Hong Kong Environmental Protection Department.

Its nice when games have riddles hidden in them. While playing TES:Arena, I came across an unusual logical puzzle: There are 3 cells.
If Cell 3 holds worthless brass, Cell 2 holds the gold key.
If Cell 1 holds the gold key, Cell 3 holds worthless brass.
If Cell 2 holds worthless brass, Cell 1 holds the gold key.
Knowing this brave fool, and knowing that all that is said cannot be true, which cell contains the gold key?
The correct answer is Cell 2 as suggested by the game. I wanted to know how one could logically arrive at the result. Could anyone help me with this?
What I tried: I negated all the above statements. The first implication became Cell 3 holds worthless brass AND Cell 2 does not have gold key. But if this is true, then cell 2 does not have the gold key and the result is incorrect. Hence I had this doubt.
PS: Choosing the wrong door causes man eating spiders to be released.

Does each cell necessarily contain either worthless brass or a gold key? – Sp3000 Dec 20 '12 at 12:55
Although not stated in game, there is only ONE cell with a gold key. The other cells may/may not have brass. – Gautam Shenoy Dec 20 '12 at 12:57

If you label the conditions a-c, and if the gold key exists and is unique, it is enough to show that not in 2 leads to a contradiction. But 'key not in 2' leads to 'key in 2' (so a contradiction), as follows:
By (c), not in 2 implies in 1. By (b) then, not in 3. By (a) then, key is in 2. Contradiction.
To be safe, you can check if the game makers messed up:
As 'key in 1' is a sub chain of the above, it also leads to 'key in 2'. Contradiction.
Similarly, 'key in 3' means by uniqueness that 2 holds brass, which, by (c), implies 1 holds the key. Contradiction.
Finally note that if the key is in 2, it doesn't lead to any contradictions. So game is correct.

Cell 2 cannot hold worthless brass, and cell 1 cannot have the gold key.
If a cell can have neither brass nor key, then that is the limit of what you can conclude. For example, your conditions are consistent with cell 3 having the key and there being nothing in the other cells.
But if every cell contains either brass or key, then you know cell 2 has the key. You can prove that by assuming cell 2 did not have the key, and hence had worthless brass. That implies that cell 1 has the key, which implies cell 3 has worthless brass which implies that cell 2 has the key. Contradiction.
However, if that additional condition were part of the problem, then your middle condition would be redundant.

Sorry to be contrary, but I believe you need 2 assumptions for there to be a unique solution. First, that all 3 statements are indeed true. If we allow that one or more of those statements doesn't hold, the whole thing falls apart.
Second, that each cell contains either brass or the key. No empty cells. If you disagree, try looking at these 2 solutions:
Cell 1 = Empty, Cell 2 = Key, Cell 3 = Empty
Cell 1 = Empty, Cell 2 = Empty, Cell 3 = Key
None of the 3 statements apply to either of these, so they're both possible valid solutions and you're left to guess and hope the spiders don't eat your face.
Now, you can brute force your way through by listing all possible solutions and checking which are valid under the given statements. In this case there aren't many possible choices, so that approach is not too bad. However, I'm assuming you're looking for a bit deeper insight, so I'll walk through a technique that can sometimes provide a quicker route to the answer, especially in more complex puzzles.
Since all the implications are one way (they are "if", not "if and only if"), one approach is to start by assuming a condition from the left side of a statement and trace the implications through all the statements to look for inconsistencies.
Just going in order, let's assume first that Cell 3 holds brass. Then by statement 1, Cell 2 holds the key. Since we're assuming key or brass in each and only one key, then Cell 1 would have to be brass. Given that, neither of the last 2 statements apply, so this solution is possible with no contradictions. Let's continue and check the others to be sure we have the only possible valid solution.
Looking at statement 2, let's assume now that Cell 1 holds the key. By statement 2, Cell 3 holds brass. By statement 1, Cell 2 holds the key. Since only 1 cell can hold the key, this is a contradiction. Therefore our original assumption is false, so Cell 1 does not hold the key.
Lastly, look at the third statement. If we assume Cell 2 holds brass, then Cell 1 holds the key. But we already know by our last reasoning that if Cell 1 holds the key we end up with a contradiction. So our assumption here is false, and Cell 2 does not hold brass.
Since Cell 2 cannot hold brass, it must hold the key.

If you take "not all that is said is true" to mean that at least one statement is false, you can go through negating them and see where it leads. If the first statement is false, you have 3 holds brass and 2 does not hold the gold key. Given that there is a gold key, it must be behind door 1. Then the second and third statements would be true, but we still don't know whether cell 2 holds brass.
If the second statement is false, cell 1 has gold and 3 does not have brass (so is empty). The first and third sentences are then true and we again know nothing about cell 2.
If the third statement is false, 2 holds brass and 1 does not have gold, so it must be cell 3 that has gold. The other two are then true and we don't know what 1 holds.
Since we didn't reach a contradiction from any of these, we can't choose between them. I would downvote the puzzle creator. However, if you ignore the "not all that is said is true" and believe them all, gnometorule has shown how to get there.

John V. Murra, a professor of anthropology who culled voluminous Spanish colonial archives for research that reshaped the image of the Incas and their vast South American empire, died on Oct. 16 at his home in Ithaca, N.Y. He was 90.
The death was confirmed by Blaine Friedlander, a spokesman for Cornell University, where Professor Murra taught from 1968 until his retirement in 1982.
"Before he came along, the image of the Incas was one of barbaric splendor," said Frank Salomon, the John V. Murra professor of anthropology at the University of Wisconsin-Madison. But Professor Murra's work "forged a radically new image" of that empire, Professor Salomon said — one based on an intricate and often ceremonial exchange of produce as gifts among tribal kinfolk. They hiked from the edges of the rain forest to meet those living at the heights of the Andes, ensuring each other's survival by trading key lowland crops like maize and potatoes for scarce mountain goods like llama and alpaca wool. That economic system was named "the vertical archipelago" by Professor Murra.
"His 'vertical archipelago' model has been verified through research
that archaeologists have since done in the Andean zone," said Heather
Lechtman, a professor of archaeology and ancient technology at the Massachusetts Institute of Technology.
While some experts debate aspects of the theory, Professor Lechtman
said, "This is certainly the accepted model for the central Andes."

Murra's papers are at the National Anthropological Archives of the Smithsonian Institution, according to a press release issued in 2005 announcing the availability of a finding aid [.pdf] to the collection. The press release also includes additional biographical information:
The National Anthropological Archives is pleased to announce the availability of a Register to the Papers of John Victor Murra, an anthropologist and ethnohistorian whose research focuses on Andean cultures and the Caribbean. Murra is the author of Survey and Excavations in Southern Ecuador (with Don Collier, 1943); The Economic Organization of the Inca State (1956); Cloth and its Functions in the Inca State (1962); Current Research and Prospects in Andean Ethnohistory (1970); Formaciones económicas y políticas del mundo andino (1975); Historia general de América Latina / 1. Las sociedades originales (with Teresa Rojas Rabiela, 1999); and El mundo andino: población, medio ambiente y economía (2002), and is the editor of American Anthropology, the Early Years (1976) and Anthropological History of Andean Polities (with Nathan Wachtel and Jacques Revel, 1986).
Trained at the University of Chicago, Murra taught at Chicago, Vassar, the University of Puerto Rico, Brooklyn College, Yale and Cornell, and held visiting professorships in Chile, England, France, Peru and Spain. He served as the president of the American Society of Ethnohistory (1970-71), the American Ethnological Society (1972-73), and the Institute of Andean Research (1977-83). Murra's efforts to cultivate educational opportunities for South American graduate students and promote an international dialogue among students produced three well known programs: the Comparative Seminar on the Andes and Mesoamerica (1972), the Lake Titicaca field project (1973) and the Otoño Andino held at Cornell University (1977).
Following his retirement from Cornell, Murra served as a consultant to the Banco Nacional de Bolivia at the Museo Nacional de Etnografía, La Paz. In 1983, he received a Guggenheim Fellowship to pursue archival research in Spain, later teaching at the Universities of Madrid and Seville and at the Institut Catalá d'Antropologi in Barcelonia (1985-86). He was awarded the Grand Cross of the Order of the Sun, Peru, and Doctor Honoris Causa from the Universidad de Barcelona. Murra currently lives in Ithaca, New York.

Internal Wave Generation Boundary
(x max, ymax)
( xorigin, yorigin)
Definition sketch for computational grid
a. The grid axes should be aligned as much as possible with the
predominant wave direction.
b. Points of interest in the computational domain should be kept at least one
c. The water depth should be uniform along the wave generation boundary.
d. The grid spacing should be chosen to resolve the shortest wave period of
interest (Tmin) in the shallowest part of the domain (hmin). This typically
corresponds to having at least eight grid points per wavelength in the
shallow regions and 20 to 30 points per wavelength at the peak wave
period (Tp) in the deep regions (hmax).
e. The maximum water depth has to be less than half the shortest wavelength of interest (hmax ≤ L(Tmin)/2). In regions with relatively deep water
along the offshore boundary, an artificial maximum depth can be
imposed in the numerical model to ensure that the shortest waves of
interest are resolved. For example, if we are interested in modeling a sea
state with Tp =10 s and Tmin = 6 s over an area where the water depth
ranges from 5 m to 100 m, a maximum depth of 28 m can be imposed
corresponding to L(Tmin)/2.
The maximum size of the computational area should be based on the
amount of available computational resources. For typical PC's or workstations with 100 to 200 MB of virtual memory, the grid size should not
exceed 500 x 500 grid points. Larger grids can be used at the cost of
much longer computational times.
Chapter 4 Setting Up and Running BOUSS-2D


16.1 Introduction
Diskfun is a part of Chebfun for computing with 2D scalar and vector-valued functions on the unit disk. Conceptually, it is an extension of Chebfun2 to the polar setting, designed to accurately and efficiently perform over 100 operations. These include differentiation, integration, vector calculus, and rootfinding, among many other things. Diskfun was developed in tandem with Spherefun, and the two are algorithmically closely related. For complete details on the algorithms of both of these classes, see [Townsend, Wilber & Wright, 2016], [Wilber, Townsend & Wright, 2016]. Later, Ballfun was also created, for computing with functions in a spherical ball, as described in chapter 20.
To get started, we simply call the Diskfun constructor. In this example, we consider a Gaussian function.
LW = 'Linewidth'; MS = 'Markersize'; FS = 'Fontsize';
g = diskfun(@(x,y) exp(-10*((x-.3).^2+y.^2)));
plot(g), view(3)
When working with functions on the disk, it is sometimes convenient to express them in terms of polar coordinates. Given a function $f(x,y)$ expressed in Cartesian coordinates, we apply the following transformation of variables: \begin{equation} x = \rho\cos\theta, \qquad y=\rho\sin\theta, \qquad (\theta, \rho) \in [-\pi, \pi] \times [0, 1]. \end{equation} This gives $f(\theta, \rho)$, where $\theta$ is the angular variable and $\rho$ is the radial variable.
To construct g using polar coordinates, we include the flag 'polar'. The result using either coordinate system is the same up to machine precision:
f = diskfun(@(t, r) exp(-10*((r.*cos(t)-.3).^2+(r.*sin(t)).^2)), 'polar');
ans =
The object we have constructed is called a diskfun, with a lower case 'd'. We can find out more about a diskfun by printing it to the command line.
f =
 diskfun object
 domain rank vertical scale
 unit disk 19 1
The output describes the numerical rank of $f$, as well an approximation of the maximum absolute value of $f$ (the vertical scale).
To evaluate a diskfun, we can use either Cartesian (the default) or polar coordinates (with the 'polar' flag):
[ f(sqrt(2)/4, sqrt(2)/4) f(pi/4,1/2, 'polar') ]
ans =
 0.278404647671088 0.278404647671088
We can also evaluate a univariate slice of $f$, in either the radial or angular coordinate. The result is returned as a chebfun, either as a nonperiodic or periodic function, respectively. Here, we plot three angular slices at the fixed radii $\rho = 1/4$, $1/3$, and $1/2$.
c = f( :, [1/4 1/3 1/2], 'polar');
plot(c(:,1), 'r', c(:,2), 'k', c(:,3), 'b')
title( 'Three angular slices of a diskfun' )
Whenever possible, we interpret commands with respect to the function in Cartesian coordinates. So, for example, the command diag returns the radial slice $f(x,x)$ as a nonperiodic chebfun, and trace is the integral of $f(x,x)$ over its domain, $[-1, 1]$. (These are admittedly rather artificial operations.)
d = diag( f );
plot( d )
title( 'The diagonal slice of f' )
trace_f = trace( f )
int_d = sum( d )
trace_f =
int_d =
Like the rest of Chebfun, Diskfun is designed to perform operations at close to machine precision, and using Diskfun requires no special knowledge about the underlying algorithms or discretization procedures.
16.2 Basic operations
A suite of commands are available in Diskfun, and here we describe only a few. A complete listing can be found by typing methods diskfun in the MATLAB command line.
We start by adding, subtracting, and multiplying diskfuns together:
g = diskfun(@(th, r) -40*(cos(((sin(pi*r).*cos(th)...
 + sin(2*pi*r).*sin(th)))/4))+39.5, 'polar');
f = diskfun( @(x,y) cos(15*((x-.2).^2+(y-.2).^2))...
plot( g )
title( 'g' ), axis off, snapnow
plot( f )
title( 'f' ), axis off, snapnow
h = g + f;
title( 'g + f' ), axis off, snapnow
h = g - f;
plot( h )
title( 'g - f' ), axis off, snapnow
h = g.*f;
plot( h )
title( 'g x f' ), axis off
In addition to algebraic operations, we can also solve unconstrained global optimization problems. In this example, we use the command max2 to plot $f$ along with its maximum value.
[val, loc] = max2( f )
plot( f ), hold on, axis off, colorbar
plot3(loc(1), loc(2), val, 'k.', MS, 20), hold off
val =
loc =
 0.200000005872459 0.200000000131672
There are many ways to visualize a function on the disk. For example, here is a contour plot of $g$, with the zero contours displayed in black:
contour(g, 'Linewidth', 1.2), hold on, axis off
contour(g, [0 0], '-k', 'Linewidth', 2), hold off
The roots of a function (1D contours) can also be found explicitly. Following the pattern of Chebfun2, the contours are stored as complex-valued chebfuns.
r = roots(g);
plot(g), colorbar, hold on
plot(r,'k',LW,2), axis off, hold off
One can also perform calculus on diskfuns. For instance, the integral of the function $g(x,y) = -x^2 - 3xy-(y-1)^2$ over the unit disk can be computed using the sum2 command. We know that the exact answer is $-3\pi/2$.
f = diskfun(@(x,y) -x.^2 - 3*x.*y-(y-1).^2);
intf = sum2(f)
tru = -3*pi/2
intf =
tru =
Differentiation on the disk with respect to the radial variable $\rho$ can lead to singularities, even for smooth functions. For example, the function $f( \theta, \rho) = \rho \sin(\theta)$ is smooth on the disk, but $\partial f/ \partial \rho = \sin(\theta)$ has a singularity at $\rho = 0$. For this reason, differentiation in Diskfun is only done with respect to the Cartesian coordinates, $x$ and $y$.
Here, we examine a pair of harmonic conjugate functions, $u$ and $v$. We can use Diskfun to check that they satisfy the Cauchy-Riemann equations, and that $\nabla^2u = \nabla^2v = 0$. Geometrically, this implies that the contour lines of $u$ and $v$ intersect at right angles.
u = diskfun(@(t,r) r.^3.*cos(3*t), 'polar');
v = diskfun(@(t,r) r.^3.*sin(3*t), 'polar');
norm(diffy(u) + diffx(v)) % Check u_y =- v_x
norm(diffx(u) - diffy(v)) % Check u_x = v_y
ans =
ans =
ans =
ans =
contour(u, 20, 'b'), hold on
contour(v, 20,'m'), axis off, hold off
title( 'Contour lines for u and v' )
For the next example, we consider the eigenfunctions of the Laplace operator in polar coordinates. As the analogue of the the spherical harmonics, they are a natural basis for functions on the disk.
They can be accessed in Diskfun with the diskfun.harmonic command.
Here, we examine the derivatives of the cylindrical harmonic function $u = a J_4(\omega_{41}\rho) \cos(4 \theta)$. The function $J_4$ is a Bessel function with parameter 4, $\omega_{41}$ is the first positive root of $J_4$, and $a$ is a normalization constant (see Ch. 9, [Churchill & Brown, 1978]). We construct $u$ in Diskfun as follows:
u = diskfun.harmonic(4, 1);

Mannerism is the term often given to a style of Renaissance art and architecture that began in the courts of Italy in about 1520, then spread throughout Europe and lasted until about 1610. The name comes from maniera, Italian for style. The style is characterised by surprising effects and visual trickery. Decoration is often complex, figures are elongated and given exaggerated poses.

It is certainly a cross sometimes to stand up for our beliefs in the court of public opinion. As you observe the Stations of the Cross this Lent, encourage your students to pray for the citizens of the United States as we struggle to vote our consciences in this election year.
Create a Stations of the Cross with your students leading them to use each station as motivation to stand up for what is right in our classrooms, in our communities, in our country.
Make a large cross from poster board. Divide the stations among the class, having groups create each of the fourteen stations small enough to fit together on the large cross. Attach each station to the large cross and put this prayer in the center:
Dear Jesus, standing up for what is right is not easy. By praying the Stations of the Cross, may I receive Your grace and strength to always do what is right and be a good example to others. May our leaders also have the grace and strength to do what is right. Amen.
For older students, challenge them to write prayers for each station.

The prices of goods and services in America change constantly. While some brands raise their prices, others offer discounts to try to keep up with the economy. For many years now prices have been rising, which causes inflation. In times of inflation, the value of the dollar decreases meaning the dollar doesn't stretch as far as it used to. While inflation can have a negative impact on consumers and even professionals across many industries, multifamily property owners can actually benefit from it.
The KataLYST Team has been studying and keeping up with commercial real estate trends in Des Moines and surrounding communities. We also specialize in multifamily properties and are committed to helping Iowans get the most out of their investments. Read on to hear our top tips for multifamily property investors in times of inflation.
What is the impact of inflation for investors?
For many investors and property owners, inflation will negatively affect their large investments because, as we mentioned, the value of the dollar gets you less than it used to. This means that commercial property owners with long leases or contracts could potentially lose out on profits if their rates don't account for inflated costs of maintenance, construction, etc. These types of leases typically exist for commercial properties like offices or retail buildings.
But, inflation presents different opportunities for multifamily property owners. In fact, it gives them a very unique opportunity to capitalize on inflating costs. Since leases at apartments and multifamily properties typically run around 6 months to a year in duration, multifamily property owners can continually renew contracts and even raise rents each year to keep up with continually rising costs. As inflation forces rent increases for tenants, your main revenue stream as a multifamily property owner also increases.
Inflation in the Multifamily Industry
With a better understanding of inflation and how it impacts commercial property investors, we can predict what commercial real estate trends will follow. We know multifamily property owners will have a much faster turnover and can therefore keep up with inflation rates. We can then predict that they will hold on to their property investments during a time where inflation is rising since they're likely to make a better profit.
Unfortunately for other investors, this can make buying new properties difficult. If current owners are reluctant to let go of their investments, then there won't be many multifamily properties up for sale. Any available property will increase in demand, and likely price as well, creating a more competitive landscape for multifamily property investors.

It's possible to trace the earliest indigo pea cultivation–like the cultivation of Buddhist wisdom– back to India. But the word "indigo" is derived from the Greek word bapto, meaning "to immerse." Through mindfulness practice, we intentionally immerse ourselves in the reality of the present moment in order to be clear-sited and know better how to respond to daily life challenges.
The indigo dyeing process is one of transformation. To start, a garment absorbs "white indigo" (a clear liquid). Then, the indigo oxidizes in the air. The garment turns green-to-blue as it dries. This transformation takes some time, not unlike personal transformation through mindfulness study and practice.
Indigo production is a source of both beauty and suffering. The first European cash crop in Charleston was indigo peas. However, plantation profits soared because landowners enslaved laborers. Indigo production was marked by violence and revolt. What's more, synthetic and natural dyeing processes produce environmental toxins. Proper handling requires mindfulness and care.
By choosing indigo as our namesake, we acknowledge the whole of our local heritage–that which is wholesome and unwholesome, beautiful and ugly, joyful and painful. As a spiritual community, we aspire to live in such a way that a peaceful, healing, and happy continuation is possible for the Lowcountry people and land.


text: Art Brokerage: David Schluss Israeli Artist: b. 1943. David Schluss, born in Israel in 1943, began studying art at an early age. He attended school in the ancient city of Jaffa, the historical seaport in central Israel. It was there that the mystical walls of the city and the austere religion of historic churches, temples and monasteries captivated him. It was during these early years in Israel that Schluss sensed his overwhelming desire to paint. Influence from great masters such as Chagall, Miro, and Botero inspired Schluss to create his own individualized style and technique of painting. He began experimenting by painting with his hands, using no paintbrush or spatula. He says, "With the palm of my hands I can get a play of light that I could never achieve with a brush. I start with the abstract, and figures emerge."


tanner engraving
In the mid C19th the last leather tanner in Hathern, Mr. Richard Smith was declared bankrupt and was forced to sell his property and fixtures.This marked the end of a trade that started hundreds of years before.
The history of tanning in Britain. The work of an ancient tanner was unglamorous to say the least. It started with an arduous preparatory stage that could take several weeks. First, the animals skins were cleaned and softened with water. Once cleaned, the tanners still had to pound the hides to remove excess fat and flesh. Next, to loosen the hair follicles, they would either coat the hides with an alkaline lime mixture, leave the hides out to putrefy for months, or soak them in vats of urine before removal with a dull knife (scudding). In the 'bating' stage, tanners worked animal dung or brains into the skins either by beating with sticks or kneading them in a vat of faeces and water.
The combination of bacterial enzymes found in animal waste and the beating or kneading action fermented the skin and made it supple. Understandably, ancient tanneries were always found on the outskirts of towns. With the malodorous preparatory work complete, the hides were ready for tanning. From ancient times and through the 18th century, tanners used a chemical compound called tannin, derived from tree bark and certain plant leaves. Hides were stretched out on frames and immersed in vats of concentrated amounts of tannin. Tannins bind to the collagen proteins in the hide and coat them, causing them to become less water-soluble, more bacteria-resistant, and more flexible. From

The role of women empowerment and labour dependency on adoption of integrated soil fertility management in Malawi
Impact factor: 1.69 (Year: 2020)

Mponela P, Villamor GB, Snapp S, Tamene L, Le QB, Borgemeister C. The role of women empowerment and labour dependency on adoption of integrated soil fertility management in Malawi. Soil Use Manage. 2020; 00: 1–13. _URL_
This paper explores the role of women empowerment and labour on enabling farmers to cross two hurdles: adopt and intensify soil fertility management (SFM), coming after six decades of SFM research that disseminated several technologies. Despite the assertion that productivity gains cannot be realized unless drivers of soil degradation are addressed, SFM usage is low. We collected data from a systematically drawn random sample of 238 farmers, representing 30% of farming households in five villages in Malawi's Rift Valley escarpments and analysed using a double-hurdle model. Descriptive results show that 90% of the respondents used inorganic fertilizers, 72% planted legumes and 57% applied organic manure. The empirical analysis shows that one percentage point increase in dependency ratio reduces probability to apply organic amendments by 0.4 percentage points and erodes the positive influence of increasing labour on application of inorganic fertilizer. As women become increasingly empowered in decision-making, there are significant trade-offs: a percentage point increase in women empowerment in agriculture index (WEAI) potentially leads to a one-third percentage point increase in the area allocated to legumes but reduces the amount of organic manure applied with higher elasticity of two percentage points. Considering the trade-offs, sustainable intensification could be achieved by harnessing the positive influences while concurrently reducing the negative ones over a decision space. Notably, addressing the negative effect associated with women empowerment on manuring could unlock potentials for integrated SFM as women are already engaged in legume cropping.

Google thinks it has made a breakthrough in "computer vision."
Imagine stumbling upon a picture of a beautiful site in Europe filled with ancient ruins, one you didn't recognize at first glance while searching for vacation destinations online. Google has developed a way to let a person provide Google with the URL for that image and search a database of over 40 million geotagged photos to match that image to verified landmarks, giving you a destination for that next trip.
The project is still very much in the research stage, said Jay Yagnik, Google's head of computer vision research. The company plans to present a paper Monday at the Computer Vision and Pattern Recognition Conference in Miami detailing its work in proving that large, scattered sets of data can be used to make accurate assessments of individual images.
"This is a fundamental advancement in how we look at computer vision," Yagnik said.
To create the "landmark recognition engine," Google took advantage of the 40 million or so images in Picasa and Panoromio that were geotagged with the locations of famous landmarks, like the Eiffel Tower. It also assembled images from travel guide sites such as Wikitravel as a base of landmark photos that had been verified by experts.
With all that data as a backdrop, researchers figured out a way to find the most representative pictures of a landmark using a clustering technique to group images taken from similar perspectives, as well as toss out "noisy" images such as a picture of your family on the street in front of the Eiffel Tower that doesn't really show the landmark.
Then, when given a fresh image to analyze, the system uses pixel-matching techniques to find small patterns within that image and look for similar patterns within verified photos of landmarks. Google said it has been able to return an accurate result 80 percent of the time, not only naming the landmark but allowing it to supply additional information about the place.
Google is by no means certain when, or if, this research will turn into a product. It is excited, however, that it has found a way to use computers to process large sets of data available on the Internet and return accurate information about images; doing this with text, of course, is what has made Google Google.

Simply, A googol to the power of a googol
was named by Robbie in 2006.
A googol is 10^100, or 1 and a hundred zeroes.
A googolplex is (10)^(10^100), this number is impossible to write down because it is bigger then the theorized number of atoms in the universe.
A Googolplexion is a Googol, to the power of a Googol, written in exponential form it's
(10^100)^(10^100), this number is incredibly bigger then a googolplex, and is extremely hard to imagine. (a googol times itself a googol ammount of times)
A googolplexion is (10^100)^(10^100), that's a freakin lot of zeroes.

The answer lies with wavy jet stream.
by Mike Godsey, mike AT iwindsurf.com
At the Hatchery this 2016 summer season 2 topics beyond the endless chatter about sail sizes are common. Most common are: 1. Why aren't we getting the consistent 4.2 sail size winds typical of summer. It seems the average winds are either weaker than normal or stronger than normal. 1. What happened to the normal progression of warm windy days occasionally punctuated by heat waves then cloudy blasts of cool air. This has led to some calling this the Feast or Famine summer wind wise.
One thing is clear. There are a lot more upper troughs & lows at ≈ 18,000 ft. sliding past the Gorge this summer. And when they pass just a bit to the north their strong WNW to WSW winds aloft create a wind feast. But when the upper troughs & lows come too close to us, like Sunday Aug. 7, they create anything from crazy up and down winds to weak winds to "you had to be there at the right moment winds".


How to make a redstone clock in Minecraft (2024)
This article is over 2 years old and may contain outdated information
Redstone clocks are arguably the most useful contraption you can make for any large-scale redstone machine. Redstone clocks are generally pretty easy to build and implement into any of your contraptions, and are also very easy to scale, so you can make them as big or as small as you want and change the timing to suit your needs. Here are some of the easiest redstone clocks you can make in Minecraft.
Hopper Clock
How to make a redstone clock in Minecraft (1)
Out of all of the clocks on this list, this one is complex and expensive to build. It also grants you the most control over your timings. The main feature of this clock is that it is tileable and gives you a lot of control over your timings. You can place as many of these as you like into your build and set each one to fire at a different time.
The timing of this clock is controlled by the items you place into the hoppers. Each item creates a delay of 0.4 seconds. So if you want your machine to go off every minute, you need to put 150 items into the hoppers.
To build this clock, you will need the following:
 - 2 Comparators
 - 2 Sticky pistons
 - 1 Redstone block
 - 4 Redstone torches
 - 4 Blocks of wool or iron
 - 2 Hoppers
Instructions
 1. Place 2 hoppers facing each other. This way they are constantly passing their items between one another.
 2. Place a redstone block on top of the hoppers, then place the sticky pistons so they will move the block back and forth on top of the hoppers.
 3. Place the comparators next to each hopper, so they are triggered by the items running through the hoppers.
 4. Place a block next behind the comparator and place a redstone torch on the opposite side. Then place a block on top of the torch, and put another torch facing your pistons.
 5. Finally, fill the hoppers with as many items as you need. You can then connect the redstone block or torches to other machines as needed.
Repeater Clock
How to make a redstone clock in Minecraft (2)
This is probably the most well-known and most popular clock used in redstone development. It is also the cheapest of all the clocks on this list, but it can also potentially cause the most lag if you are on a server and continue scaling or tiling it. You can control the timing for this clock, but it is a bit more difficult than using a hopper clock or minecart clock.
To make this clock you will need the following:
 - 4 Redstone dust
 - 2-4 Repeaters
 - 1 Redstone torch
Making this clock is fairly easy. Alternate your repeaters and redstone dust until you have a circuit. The signal will constantly circulate through the circuit until you break it or something causes it to stop.
After you have your circuit created, you will need to place a redstone torch next to one of the pieces of redstone dust. Break the torch as soon as you place it. You just want the signal to start; you do not want it to make it all the way through the circuit. If you are fast enough, the signal will circle around the circuit you have made constantly. You can also increase the size of the circuit and add more repeaters to increase the time it takes to activate.
After you have the clock up and running, you can connect any other machine you like by just adding a line of redstone dust or repeaters that connect to it.
Minecart Clock
How to make a redstone clock in Minecraft (3)
The best and worst feature of this clock is that it is easily scalable. As long as you have the materials to make more rails or minecarts, you can scale it up indefinitely. The downside to this scalability is that this clock takes up a lot more space than any other on this list, but it is fairly easy to use if you are new to redstone.
To build this clock you will need the following:
 - At least 1 activator rail
 - At least 1 minecart
 - Powered rails
 - Redstone torches
 - Redstone dust
 - Normal minecart rails
To make this clock, all you need to do is create a circle of rails for a minecart to travel over. Place an activator rail where you would like the redstone signal to be triggered. You can place multiple activator rails to trigger multiple machines if you like. Place the powered rails with redstone torches next to them to make sure the cart always has plenty of speed.
Observer Clock
How to make a redstone clock in Minecraft (4)
This is probably the easiest redstone clock to make, though it does have some drawbacks. This clock will tick constantly, which can be a bit annoying to your friends or members of your server and can cause a little lag if you use too many. If you need something to be constantly firing, this clock is a quick and easy fix.
All you need to create this clock is a pair of observers.
Place two observers facing each other, and they will start constantly ticking each other. You can connect any redstone device to the back of these observers to trigger it.

text: Critical Archives is a Digital History Seminar that examines archives as sites and sources of history. As sources of history, archives preserve, contextualize, and ensure access to cultural heritage. As sites of history, archives are institutions generated from places of power that frequently replicate the logic of information gathered for the purposes of political, social, and economic control. Attuned to these institutional legacies and their impact on the production of history, activists, scholars, and heritage professionals have developed new methods for creating and interpreting archives. Critical Archives explores these methods through historical scholarship, archival theory, and digital humanities practice.
