# CNXML 0.5 Stress Test

Summary: This module attempts to use all of the CNXML 0.5 tags. It supplies exaples of all the tags. People interested in this module would be those who are learning CNXML and those who need an example for testing, such as stylesheets. (Note that I have not yet added 'glossary' or 'seealso' elements.)

This brief paragraph was put in before a section tag to ensure that it was styled correctly.

## This equation has been thrown in as a child of content for styling purposes.

cos2πft=ei2πft+e(i2πft)2 2 f t 2 f t 2 f t 2
(1)

## General Example with Equation

The complex exponential defines the notion of frequency: It is the only signal that contains only one frequency component. The sinusoid consists of two frequency components: one at the frequency + f 0 + f 0 and the other at f 0 f 0 .

### This is Euler's relation relating things like e's and cosines

cos2πft=ei2πft+e(i2πft)2 2 f t 2 f t 2 f t 2
(2)

### Euler's relation

sin2πft=ei2πfte(i2πft)2i 2 f t 2 f t 2 f t 2
(3)

### Another Euler's relation

ei2πft=cos2πft+isin2πft 2 f t 2 f t 2 f t
(4)
The complex exponential signal can thus be written in terms of its real and imaginary parts using Euler's relation. Thus, sinusoidal signals can be expressed as either the real or the imaginary part of a complex exponential signal (the choice depends on whether cosine or sine phase is needed) or as the sum of two complex exponentials. These two decompositions are mathematically equivalent to each other.

## Section: ICSA

The Rice Sailing Team is part of a sailing coalition called ICSA which stands for Inter-Collegiate Sailing Association. The ICSA is the governing body for collegete sailing programs in the US. Volunteers of ICSA develop the racing rules. They also organize the national regattas. To be a member of ICSA, a college must pay money to a sub-district.

### SEISA

Rice is a member of the SEISA district of ICSA. SEISA stands for South-Eastern Inter-Collegiate Sailing Association. SEISA is the organization that the South-East colleges compete in. The schools gather to compete for all normal regattas. One or two schools from SEISA will qualify for the National competitions hosted by ICSA.

#### RUST: Rice University Sailing Team

RUST is Rice's competitive sailing team. Rice is a member of SEISA. This district is made up of several schools, including UT, A&M, A&M Galveston, UNO, Tulane, Kansas, and UWF. The Rice Sailing Club is open to all members of the student community, including graduate students. Beginner and expert sailors alike are encouraged to practice with the team. RUST is a small and easy-going club. There are no attendance requirements, and everyone who wants to sail can sail. Members pay yearly dues to help cover expenses, but every member not only gets to sail, but gets a sailing club T-shirt too!

For the benefit of Mr. Kite, there will be a show tonight on trampoline. The Hendersons will all be there, late Pablo Fanques Fair - what a scene. Over men and horses, hoops and garters, lastly through a hogshead of real fire! In this way Mr. K. will challenge the world! The celebrated Mr. K. performs his feat on Saturday at Bishopsgate. The Hendersons will dance and sing as Mr. Kite flys through the ring - don't be late. Messrs. K and H. assure the public their production will be second to none. And course Henry The Horse dances the waltz!

## List

Hello and welcome to my list of things to do. The following list is within a paragraph, whereas the subsequent ordered list is preceded by a paragraph.

• This is an item. The length of this item has been extended for quality assurance of its style upon wrapping, assuming it extends for more than the width of the screen, which is why it may appear that I am dragging this sentence out for a long time..
• This is another item with a list nested inside of it.
• The next subitem contains a named equation.
• ### Euler's relation

sin2πft=ei2πfte(i2πft)2i 2 f t 2 f t 2 f t 2

This is not a new paragraph. This is also not a new paragraph.

This is a new paragraph.

### Example Enumerated List

1. This is an enumerated list item not located within paragraph tags.
2. This is another item with a list nested inside of it.
• This is a subitem. But the subitem is not enumerated.
• This is another subitem.
3. Yet another item

• #### Theorem 1: Pythagorean Theorem

On a right triangle, the sum of the squares of the sides equals the square of the hypotenus.

##### Example

Take a right triangle whose sides are of length 3, 4, and 5. In this case the sum of the square of the two shorter sides is 9+16=25. The square of the hypotenus is 25. So the theorem holds.

## Example

### Example 1

As an example of signal complexity, we can express the pulse p Δ t p Δ t as a sum of delayed unit steps.

p Δ t=ututΔ p Δ t u t u t Δ
(8)

Thus, the pulse is a more complex signal than the step. Be that as it may, the pulse is very useful to us.

### Example 2: CNXML can be a pain

This sentence, although it is very unimportant and irrelevant, contains emphasis within the <example> tag. For an example of <cite> within <example>, see Things That Are a Pain to Style in CNXML by Max Starkenburg. For an example of <emphasis> within <cite> within <example>, please see Things That Are a Pain in the Butt to Style in CNXML, also by Max Starkenburg. This sentence contains emphasized codeline within an example. This sentence contains a cnxn within an example. This sentence contains a link. This sentence contains a term. This sentence contains a codeline term.

This paragraph has just been thrown in to ensure that it is styled correctly. It has nothing to say, but is long anwyay, just to make sure that it continues to the next line.

## Exercise

### Exercise 1

Express a square wave having period T T and amplitude A A as a superposition of delayed and amplitude-scaled pulses.

This is an extra paragraph thrown in for styling purposes.

#### Solution

This is a paragraph that begins a solution. The equation is nested in the paragraph.

t=n=1nA p T / 2 tnT2 t n 1 n A p T / 2 t n T 2
(9)

This is an extra paragraph thrown in for styling purposes.

### Exercise 2

#### This equation has been thrown in as a child of problem for styling purposes

cos2πft=ei2πft+e(i2πft)2 2 f t 2 f t 2 f t 2
(10)

#### Solution

The solution is to use Mozilla, and not IE, nor Netscape. The latter two browsers have serious CSS bugs. For an equation inside a solution, see the above exercise.

## Codeline and Codeblock

Try running this in MATLAB.


for n=1:1000
y(n) = sum(a.*y(n-1:-1:n-p)) + sum(b.*x(n:-1:n-q));
end


The for command repeats its contents while incrementing a counter.

<!-- some codeline and codeblock are emphasized more than others -->

<!-- codeline can be linked and cnxn'ed too -->


codeblock
can be
cnxn'ed
as well


## Definition, Term, Meaning, and Example

Definition 3: note
1. A short letter.

### Example

2. A different meaning for the term.

A first example.

### Example

A second example.

I can also define a new term in the middle of a sentence. A term is a new word that is being defined for the first time.

The following definition will be the child of a <para> tag to ensure that it is styled well.

Definition 4: #!/usr/local/bin/perl/
The first line of every Perl program

### Example

This program will produce a 2-column listing of a file.


#!/usr/local/bin/perl/
while( $1 = >STDIN> ) { chop($1 );
if( $1 =~ s/^Desig:\s+// ) {$desig = $1; next; } if($1 =~ s/^Area:\s+// ) {
$area =$1;
printf( "%-12s %\n", $desig,$area );
}
}


This sentence contains a term which is half regular half codeline.

Feast your eyes on this: #!/usr/local/bin/perl/ is a term smack dab in the middle of a sentence! Amazing! This example, #!/usr/local/bin/perl/ , is a codeline term with emphasis on /local/. The next example is a codeline term with a link and cnxn.

Definition 5: equation

## Rule

### Theorem 3: Pythagorean Theorem

On a right triangle, the sum of the squares of the sides equals the square of the hypotenus.

#### Proof: This proof was thrown into to have a child of equation for styling purposes

cos2πft=ei2πft+e(i2πft)2 2 f t 2 f t 2 f t 2
(12)

#### Example

Take a right triangle whose sides are of length 3, 4, and 5. In this case the sum of the square of the two shorter sides is 9+16=25. The square of the hypotenus is 25. So the theorem holds.

### property 1

If st s t is real, c k = c k * c k c k *

This result follows from the integral that calculates the c k c k from the signal. Furthermore, this result means that Re c k =Re c k Re c k Re c k : The real part of the Fourier coefficients for real-valued signals is even. Similarly, Im c k =Im c k Im c k Im c k : The imaginary parts of the Fourier coefficients have odd symmetry. Consequently, if you are given the Fourier coefficients for positive indices and zero and are told the signal is real-valued, you can find the negative-indexed coefficients, hence the entire spectrum. This kind of symmetry, c k = c k * c k c k * , is known as conjugate symmetry. We can phrase the property concisely by saying:

#### property 2

Real-valued periodic signals have a conjugate-symmetric spectrum.

The Fourier series obeys:

### Theorem 4: Parseval's Theorem

Power calculated in the time domain equals the power calculated in the frequency domain.

1T0T s 2 tdt=k=| c k |2 1 T t 0 T s 2 t k c k 2
(13)
This result is a (simpler) re-expression of how to calculate a signal's power than with the real-valued Fourier series expression for power .

## Quotes and Foreign Terms

Two new elements added in CNXML 0.5 are quote and foreign. A quote of type "block" might look like this:

I define the real as that which holds its characters on such a tenure that it makes not the slightest difference what any man or men may have thought them to be, or ever will have thought them to be, here using thought to include, imagining, opining, and willing (as long as forcible means are not used); but the real thing's characters will remain absolutely untouched. --C.S. Peirce, Collected Papers 6.495.
Anyone involved in interface design and usability should consider Einstein's axiom (shown here in a quote of type 'inline'): Everything should be made as simple as possible, but not one bit simpler.

In order to appear urbane and literate, we should liberally sprinkle our discourse with foreign terms and phrases, such as Fahrvergnügen and sang-froid.

### irrelevant:

It is possible to include a block quote inside a note, with foreign elements interspersed:
"Freundschaftsbezeigungen" seems to be "Friendship demonstrations," which is only a foolish and clumsy way of saying "demonstrations of friendship." "Unabhängigkeitserklärungen" seems to be "Independencedeclarations," which is no improvement upon "Declarations of Independence," so far as I can see. "Generalstaatsverordnetenversammlungen" seems to be "General-statesrepresentativesmeetings," as nearly as I can get at it -- a mere rhythmical, gushy euphuism for "meetings of the legislature," I judge. --Mark Twain, "The Awful German Language"

## Conclusion

For more information on all of the CNXML used in this module, please refer to the CNXML Spec.

## Footnotes

1. Sulfuric and Hydrochloric Acid are very dangerous. Please handle with caution.
2. This note was added to test styling.
3. Sulfuric and Hydrochloric Acid are very dangerous. Please handle with caution. Also handle this note with caution, because it contains the attribute type="FOOTNOTE", not type="footnote", and will thus be styled differently.
