Give instructor top 3 project choice list
Typically the instructor picks teams. Students send the instructor their top 3 choices. The project choices are typically those found at Category:General_Engineering_Projects. The instructor tries to put students in the project of their choice. Put your top three choices here after they are used to assign you to this project. Create a link to the project root and to where your team will be working.

Write problem statement
Look through the existing problem statements. Find something not yet done on the project. Create a problem statement for it. Think of a new subsystem that needs to be built for the project. The goal is something simple, possible, for zero dollars.

Assign Task1
Tasks are typically done over the weekend. They are documented during the week, presented during the week and the next weekends work is negotiated during the week. Week 0 is the week that task 1 is negotiated. Record your individual task here. Plan on working on it during the weekend between week0 and week1.

Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called Patchwolf. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Patchwolf~enwikiversity that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 23:47, 17 March 2015 (UTC)

Renamed
 This account has been renamed as part of single-user login finalisation. If you own this account you can |log in using your previous username and password for more information. If you do not like this account's new name, you can choose your own using this form after logging in: . -- Keegan (WMF) (talk) 06:17, 19 April 2015 (UTC)

User:Ndelaney9295/enes100/poppit

Back to Jupiters team page.

Give instructor top 3 project choice list
As the initial project for this class, all teams were given the same project, Chunk Poppit.

Write problem statement
The goal is to determine a way to play the game Poppit ("the game") in such a way as to, rather than simply beat the game, clear the screen of all balloons every time. I believe that there will be a way to do so by targeting specific colors and locations on the 10x15 grid.

Assign Task1
I am to determine if there is a pattern for how the grid is set up at the beginning of each game. If so, use that pattern to determine an algorithm to eliminate all the balloons. If not, determine an alternate method of accomplishing the goal.

Compare actual work done to Task1
I counted the number of each type of balloon for several initial setups of the game. The initial amounts ranged from 23-34 (30 should be the average, based on the fact that the grid is 10x15 and contains 5 colors of balloons). There did not seem to be any particular pattern for the initial setup. Using the low/high amount of balloons, I tried several games each of eliminating the highest amount first, eliminating the lowest amount first, eliminating the highest amount last, and eliminating the lowest amount last. The best score I obtained using these methods was 11 balloons remaining. I then decided that since the game ends when no balloon on the grid is lined up with any other balloon of the same color, I should focus on eliminated "solitary" balloons first. I tried this starting from the top of the grid, the bottom, the sides, and the middle. The lowest score I obtained (while trying from the top and middle) was 8 balloons remaining.

Week1 Peer Review
Go to each team mates weekly summary wiki page. Read their activities and narrative. Then go the associated discussion page. Say something positive on this page. Try some constructive criticism. Add your name and 1sfoerster 13:32, 28 August 2011 (UTC) to create a time and date stamp. Create a new category if another team mate has already commented here.

HW2| = R2.9 State and proof the full theorem =

Given
Review calculus, and find the minimum degree of differentiability of the function such that (2) p.9-3 is satisfied. State the full theorem and provide a proof. p.9-3 (2): $$ \frac{\partial^2 \phi(x,y)}{\partial x \partial y}=\frac{\partial^2 \phi(x,y)}{\partial y \partial x} $$

Clairaut's theorem
In mathematical analysis, Clairaut's theorem or Schwarz's theorem,[1] named after Alexis Clairaut and Hermann Schwarz, states that if $$f:\mathbb R \rightarrow \mathbb R$$ has continuous second partial derivatives at any given point in $$ \mathbb R^n $$,say $$(a_1,...,a_n)$$, then for $$ 1<i,$$  $$ j<n,$$

$$\frac{\partial^2 f}{\partial x_i \partial x_j}(a_1,...,a_n)=\frac{\partial^2 f}{\partial x_j \partial x_i}(a_1,...,a_n)$$

In words, the partial derivations of this function are commutative at that point. One easy way to establish this theorem (in the case where n = 2, i = 1, and j = 2, which readily entails the result in general) is by applying Green's theorem to the gradient of f.

http://en.wikipedia.org/wiki/Symmetry_of_second_derivatives#Clairaut.27s_theorem

Solution
The minimum degree of differentiability of the function such that (2) p.9-3 is satisfied is 3.

As Clairaut's theorem mentions, functions that satisfy (2) p.9-3 must have continuous second derivative.

For instance,

$$ z=f(x,y)=x^2+y^2 $$

$$\frac{\partial^2 f(x,y)}{\partial x\partial y}=\frac{\partial^2 f(x,y)}{\partial y\partial x}=2$$

The function

$$ z=f(x,y)=x^2+y^2 $$

can only be differentialed by 3 degrees

$$ \frac{\partial^2 f(x,y)}{\partial^2 x}=0 $$

And functions with degree of differentiability less than 3 can not satisfy (2) p. 9-3

For example f(x,y)=x+y

So The minimum degree of differentiability of the function such that (2) p.9-3 is satisfied is 3.

= R*2.14 Solve the general L1-ODE-VC=

Part 1
Solve the general L1-ODE-VC

Given
$$ a_1(x)\,y'+a_0(x)\,y=b(x)$$ $$\displaystyle (Equation\;14.1) $$

where

$$ a_1(x)=1,

a_0(x)=x,

b(x)=2x+3 $$

Solution
Substituting the conditions into 14.1

$$ y'+xy=2x+3$$ $$\displaystyle (Equation\;14.2) $$

Equation 14.2 is of the form

$$ y'+P(x)y=Q(x)$$

The integrating factor for this form is

$$ I(x)=\exp[P(x)dx]$$

For equation 14.2, the integrating factor is

$$ I(x)=\exp[\int xdx]=\exp[\frac{x^2}{2}] $$

Applying the integrating factor for equation 14.2:

$$ \exp[\frac{x^2}{2}]\frac{dy}{dx}+\exp[\frac{x^2}{2}]xy=2x\exp[\frac{x^2}{2}]+3\exp[\frac{x^2}{2}] $$ $$\displaystyle (Equation\;14.3) $$

(Eq.14.3) reduces to

$$ \frac{d}{dx}(y\exp(\frac{x^2}{2}))=2x\exp[\frac{x^2}{2}]+3\exp[\frac{x^2}{2}] $$

Integrating

$$ y\exp(\frac{x^2}{2})=\int 2x\exp[\frac{x^2}{2}]dx+\int3\exp[\frac{x^2}{2}]dx $$

Results in the following equation:

$$ y\exp(\frac{x^2}{2})=2\exp[\frac{x^2}{2}]+\int 3\exp [\frac{x^2}{2}]dx $$

There is no known anti-derivative of the last term, so using mathematical analysis tools the last therm results in the error-function. So that rearranging the equation we get for y(x):

$$ y=2+3\exp[\frac{x^2}{2}][\sqrt{\frac{\pi}{2}}erfi(\frac{x}{\sqrt2})] $$

Part 2
A general solution from the integrating factor method

Given
Assume $$ a(x)\ne0 $$ for all x, rearranging equationg 14.1 gives $$ y'+\frac{a_0(x)}{a_1(x)}y=\frac{b(x)}{a_1(x)} $$ $$\displaystyle (Equation\;14.4) $$

Find
Find an expression for $$ y(x) $$ in terms of $$ a_0, a_1 $$ and b

Solution
Define $$P(x)=\frac{a_0(x)}{a_1(x)}$$ and $$Q(x)=\frac{b(x)}{a_1(x)}$$

Equation 14.4 is then in the form

$$y'+P(x)y=Q(x)$$

The integrating factor for this form is

$$I(x)=\exp[\int{P(x)}dx]$$

Introducing a dummy factor t and substituting in for P(x)

$$\exp[\int^x{\frac{a_0(t)}{a_1(t)}}dt]\frac{dy}{dx}+\exp[\int^x{\frac{a_0(t)}{a_1(t)}}dt]\frac{a_0(x)}{a_1(x)}y=\frac{b(x)}{a_1(x)}\exp[\int^x{\frac{a_0(t)}{a_1(t)}}dt] $$

Reducing

$$\frac{d}{dx}[\exp[\int^x\frac{a_0(t)}{a_1(t)}]y]=\frac{b(x)}{a_1(x)}\exp[\int^x\frac{a_0(t)}{a_1(t)}dt]$$

Integrating

$$y=A\exp[-\int\frac{a_0(t)}{a_1(t)}dt]+\exp[-\int^x\frac{a_0(t)}{a_1(t)}dt]\int^x\frac{b(s)}{a_1(s)}ds\exp[-\int^s\frac{a_0(t)}{a_1(t)}dt]ds$$

Part 3
Solution to linear, first order, ordinary differential equation with varying coefficients using Euler integrating factor method.

Solution
Given an equation in the form of 14.1, where

$$a_1(x)=x^2+1, a_0(x)=x,$$ and $$b(x)=2x,$$

Equation 14.1 becomes

$$(x^2+1)y'+xy=2x$$

Rearranging

$$y'+\frac{x}{x^2+1}y=\frac{2x}{x^2+1}$$$$\displaystyle (Equation\;14.5) $$

Equation 14.5 is in the form

$$y'+P(x)y=Q(x)$$|| $$\displaystyle (Equation\;14.6) $$

The integrating for this form is

$$I(x)=\exp[\int{\frac{x}{x^2+1}}dx]=\exp[\frac{1}{2}\ln(x^2+1)]=\sqrt {x^2+1} $$ $$\displaystyle (Equation\;14.7) $$

Multiply 14.6 by 14.7 and simplify

$$\frac{d}{dx}(y\sqrt {x^2+1})=\frac{2y}{\sqrt {x^2+1}}$$ $$\displaystyle (Equation\;14.8) $$

Integrating

$$\int^x\frac{d}{dx}(y\sqrt {x^2+1})=\int^x \frac{2y}{\sqrt {x^2+1}}dy$$$$\displaystyle (Equation\;14.9) $$

Gives

$$Y=2$$

=R*2.15 Show the necessity of constant k1 and k2=

Given
Since (2)-(3) p.11-3 is an L1-ODE-VC, there should be only one integration constant, not two.

k1 is contained in (3) p11.4

$$ h(x)= \exp[ \int a_0(s)ds +k_1]$$

k2 is contained in (1) p11.5

$$y(x)=\frac{1}{h(x)}[\int^xh(x)b(s)ds+k_2]$$

Find
Show that the integration constant k1 in (3 ) p.11-4 is not necessary, i.e, only k2 in (1) p.11-5 is necessary.

Solution
To show this we will use (6)p10.3 and show that k1 cancels out of the equation, but we must find the contants k1 and k2 from equations(eq8.1) and (eq8.2)

$$y(x)=\frac{1}{h(x)}\int^xh(s)b(s)ds$$

When we perform the integration in the RHS of (eq8.1) it becomes

$$\exp[\int^x a_0(s)ds]=\exp[\int a_0(x)dx+k]$$

Using the properties for exponential functions

$$\exp[a+b]=\exp[a]exp[b]$$

Now (eq8.3) becomes

$$\exp[\int a_0(x)dx]\underbrace{\exp[k]}_{=:k_1}$$

Plugging this back into (eq8.1) gives us

$$h(x)= k_1\exp[\int a_0(x)dx]$$

To find k2 we will evaluate the integral in (eq8.2)

$$\int^x h(s)b(s)ds=\int h(x)b(x)dx+k_2$$

Finally plug equations (eq8.5) and (eq8.6) into (6) p.10-3

$$y(x)=\frac{1}{\cancelto{}{k_1}\exp[\int a_0(x)dx]}[\int \cancelto{}{k_1}\exp[\int a_0(x)dx]b(x)dx+k_2]$$

This shows k1 is not necessary

$$y(x)=\frac{1}{\exp[\int a_0(x)dx]}[\int \exp[\int a_0(x)dx]b(x)dx+k_2]$$

= R3.1 =

Given
Show that the N1-ODE (1) p.13-2

$$ \underbrace{\bar b(x,y) c(y)}_{\displaystyle\color{blue}{N(x,y)}} \, y' + \underbrace{a(x) \bar c(x,y)}_{\displaystyle \color{blue}{M(x,y)}}=0 $$

satisfies the condition (2) p,11-2 :

$$\frac{h_x}{h}=-\frac{1}{N}(N_x-M_y) \, =: \color{blue}{n(x)}$$

that an integrating factor h(x) can be found to render it exact, only if $$k_1(y)=d_1$$

Show that (1) p.13-2 includes (1) p.12-4

$$ M+Ny'=[a(x)\, y+k_2(x)] + \bar b(x) \,y'=0 $$

as a particular case.

Solution
=*R3.3 =

Given
$$ a(x)=sinx^3 $$

$$ b(x)=cosx $$

$$ c(y)= \exp(2y) $$

1.Find an N1-ODE of the form (1) p.13-2

$$ \underbrace{\bar b(x,y) c(y)}_{\displaystyle\color{blue}{N(x,y)}} \, y' + \underbrace{a(x) \bar c(x,y)}_{\displaystyle \color{blue}{M(x,y)}}=0 $$

$$\,(Eq.3.1)$$

that is either exact or can be made exact by IFM. (See R3.1)

2.Find the first integral

$$\phi(x,y)=k $$

Solution
Part 1

$$\bar b(x)= \int\limits^x b(s)ds= \int\limits^x cos(s)ds= sin(x) $$

$$\bar c(y)= \int\limits^y c(s)ds= \int\limits^y \exp^{2s}ds= \frac{1}{2}\exp^{2y}$$

Now Eq 3.1 becomes:

$$sin(x)e^{2y}y'+\frac{1}{2}sin(x^3)e^{2y}=0$$ $$\,(Eq.3.2)$$

Eq 3.2 is the form of

$$M(x,y)+N(x,y)\,y'=0$$ and the first condition of Exactness is satisfied. $$\,(Eq.3.3)$$

The condition below is not only necessary but also sufficient for Eq 3.2 to be an exact differencial equation.

$$\frac{\partial M}{\partial y}=\frac{\partial N}{\partial x}$$

$$\frac{\partial M}{\partial y}=\frac{\partial(\frac{1}{2}sin(x^3)\exp^2y)}{\partial y}=sin(x^3)\exp^2y$$ $$\,(Eq.3.4)$$

$$\frac{\partial N}{\partial x}=\frac{\partial(sin(x)\exp^2y)}{\partial x}=cos(x)\exp^2y$$ $$\,(Eq.3.5)$$

Eq 3.4 and Eq 3.5 reveals that

$$\frac{\partial M}{\partial y} \neq \frac{\partial N}{\partial x}$$

Hence the Eq.3.2 is not exact.

But it can be made exact by using Integrating factor method.Refer to Eq(2), page 11-2 of the lecture notes, and let's multyply Eq 3.2 by h(x) in order to have an exact differential equation.

$$h(x)=exp[\int^x(-\frac{1}{N}(N_x-M_y))dx]$$

We can rewrite Eq 3.2 by cancelling $$e^{2y}$$from both term as:

$$\underbrace{sin(x)}_{N(x,y)}{y'}+ \underbrace{\frac{1}{2}sin(x^3)}_{M(x,y)}=0 $$

Now:

$$ h(x)=exp[\int^x(-\frac{1}{sin(x)}(cos(x)-0))dx]=exp[\int^x(-\frac{cos(x)}{sin(x)})dx]=exp[-ln(sin(x))]=\frac{1}{sin(x)}$$

$$\,(Eq.3.6)$$

Now Exact differential equation is given by

$$h(x)[sin(x)e^{2y}y'+\frac{1}{2}sin(x^3)\frac{1}{sin(x)}=0]$$

That is

$$sin(x)\frac{1}{sin(x)}y'+\frac{1}{2}sin(x^3)\frac{1}{sin(x)}=0$$

$$y'+\frac{1}{2}{sin(x^3)}{sin(x)}=0$$ $$\,(Eq.3.7)$$

Part 2 We know that

$$M(x,y)=\phi_x(x,y)$$
$$\,(Eq.3.8)$$

$$N(x,y)=\phi_y(x,y)$$
$$\,(Eq.3.9)$$

Also,

$$\phi_x(x,y)=\frac{\partial\phi(x,y)}{\partial x}$$
$$\,(Eq.3.10)$$

$$\phi_y(x,y)=\frac{\partial\phi(x,y)}{\partial y}$$
$$\,(Eq.3.11)$$

By integrating Eq.3.10 and 3.11 with respect to x, y, respectively, we can have equations as given below.

$$\int \phi_x(x,y)dx=\phi(x,y)=\int M(x,y)dx +k(y)$$
$$\,(Eq.3.12)$$

$$\int \phi_y(x,y)dy=\phi(x,y)=\int N(x,y)dy +k(x)$$
$$\,(Eq.3.13)$$

Now we can calculate $$k(y)$$ by differentiating Eq 3.12 with respect to y and equating to Eq 3.9=>

$$k'(y)=N(x,y)=1$$

Now integrate the above equation =>

$$k(y)=y+k1$$

Then$$\phi(x,y) $$ is obtained by substituting

$$k(y)$$ in Eq 3.12

$$\phi(x,y)=\int M(x,y)dx+y+k1$$

That is

$$\phi(x,y)=\frac{1}{2}\int \frac{sin(x^3)}{sinx}dx +y=k$$

=*R3.11 SC_L1_ODE_CC=

Given
Use (2)-(3) p.15-4 together with (1) p.14-4 to show (3) p.15-3. (2) p.15-4

 * $$\displaystyle \frac{d}{dt} \mathbf{\Phi}(t,t_0)= \mathbf{A} \, \mathbf{\Phi}(t,t_0)$$

$$\,(Eq.11.1)$$

(3) p.15-4

 * $$\mathbf \Phi (t_0,t_0)= \mathbf I$$

$$\,(Eq.11.2)$$

(1) p.14-4

 * $$\mathbf{\dot{x}}(t)= \mathbf{A}(t) \, \mathbf{x}(t) + \mathbf{B}(t) \, \mathbf{u}(t)$$

$$\,(Eq.11.3)$$

(3)p.15-3

 * $$ \mathbf{x}(t)=\mathbf{\Phi}(t,t_0) \mathbf{x}(t_0) + \int^t_{t_0} \mathbf{\Phi}(t, \tau) \, \mathbf{B}(\tau) \, \mathbf{u}{\tau} \, d\tau $$

$$\,(Eq.11.4)$$

Solution
Substituting$$\mathbf{x}(t)$$ in Eq11.1 by $$\mathbf{\phi}(t,t_0)$$
$$\,(Eq.11.5)$$

to obtain the differential equation of the state transition matrix, we get:

 * $$ \dot\phi (t,t_0)=A \mathbf{\phi}(t,t_0) + B u(t)$$

Re-arranging equation 11.5 in the following form:

 * $$\underbrace{1}_{N}\dot\phi - \underbrace{A \phi(t,t_0)}_{M}=Bu(t)$$

$$\,(Eq.11.6)$$

It is clear that this equation complies with the first condition of exactness.

So to make this equation exact we will apply the Euler Integrating Factor Method.

It has been previously shown that in order to meet the second condition of exactness we can multiply equation 11.6 by a function h to obtain the following:

 * $$\underbrace{h1}_{N}\dot\phi - \underbrace{hA \phi}_{M}=hBu$$

Now the second condition of exactness may be applied, where x is the dependent variable and t is the independent variable.

 * $$\underbrace{(h \frac{\partial M}{\partial{\phi}}+M \frac{\partial h}{\partial{\phi}})}_{\frac{\partial M}{\partial{\phi}}}=\underbrace{(h \frac{\partial N}{\partial{t}}+N \frac{\partial h}{\partial{t}})}_{\frac{\partial N}{\partial{t}}}$$

Now for the special case where $$h_x$$ equals zero we obtain the following:

 * $$hM_\phi=hN_t+Nh_t$$

Which may be rearranged to obtain:

 * $$hN_t+Nh_t-hM_\phi=0$$

We can now solve for h as a function of t.

 * $$h(t)=e^{-\int^t_{t_0}\frac{1}{N}(N_t-M_\phi)dt}$$

Where:
 * $$N=1$$

 * $$N_t=\frac{\partial 1}{\partial t}=0$$

 * $$M=-A \phi$$

 * $$M_\phi=-A$$

 * $$h(t)=e^{\int^t-Ads}=e^{-At}$$

$$\,(Eq.11.7)$$

Substituting 11.7 in the equation 11.6 we get

 * $$\underbrace{e^{-At} \dot\phi(t,t_0)}_{f'(x)\cdot g(x)}-\underbrace{e^{-At} \dot\phi(t,t_0)}_{f(x)\cdot g'(x)}=e^{-At} Bu(t)

$$
$$\,(Eq.11.8)$$

We should recognize equation 11.8 as the derivative of $$ (h\phi)$$ , by using the relation given in equation 11.2:

 * $$\frac{d(h\phi)}{dt}=hBu$$

Therefore, to find the solution we integrate both sides in the interval
 * $$t_0 \le \tau \le t$$

 * $$\int^t_{t_0} \frac{d(e^{-A\tau}\phi)}{d\tau}d\tau=\int^t_{t_0} e^{-A\tau}Bu(\tau)d\tau

$$
$$\,(Eq.11.9)$$

Equation 11.9 yields:

 * $$e^{-A(t-t_0)}\phi(t,t_0)-e^{-A(t_0-t_0)}\phi(t_0,t_0)+\int^t_{t_0}e^{-A\tau}Bu(\tau)d\tau$$

$$\,(Eq.11.10)$$

Re-arranging terms in equation 11.10 we obtain:

 * $$\phi(t,t_0)=e^{A(t-t_0)} \phi(t_0,t_0)+\int^t_{t_0} e^{A(t-\tau)} Bu(\tau)d\tau$$

$$\,(Eq.11.11)$$

Substituting $$\phi(t,t_0)$$ in the equation 11.11 by $$x(t)$$ we obtain the differential equation in the form of equation 11.4:

 * $$x(t)=e^{A(t-t_0)}x(t_0)+\int^t_{t_0}e^{A(t-\tau)}bu(\tau)d\tau$$

Solar

Idea
Solar energy projects start with being able to aim solar light at a target and cook something like a frozen pizza. Then they branch out into hot water systems. After that the goal is to begin working with small solar cells. Working with lasers to power them and developing robots that can be powered by lasers. Typically these are robots climbing a rope and compete in a space elevator competition. The other expensive option is to design how adding solar cells to a university building.

Static electricity

Problem
Electricity was confined to static demonstrations before the 1800's when Faraday began to experiment with moving energy through wires and creating magnetic fields. But magnetic fields are fragile, so studying fields in general starts with studying static electricity. The goal of these projects is to develop static demonstrations.

Concept
Create demonstrations after completing a variety of projects in the static electricity areas including:
 * /Fly stick/
 * /Static electricity safety/
 * /Lightning/
 * /Measuring high voltages/
 * /Creating high voltages/
 * /Dancing balls/
 * /Static motors/

Design
After the Demonstrations project has created a format for demonstrations, then need to package each of the above projects into a demonstration.

Static electricity demos are so [http://www.youtube.com/watch?v=vCBsqZXVU-s&feature=player_embedded#! interesting] because little modern technology uses static electricity. The secret is a source of electrons. Once this is made, then a tremendous number of demonstrations is possible. The goal of the project is to build the parts and develop a script for doing the demos.

Given
The Legendre differential equation:

When $$\displaystyle n=1 $$, it becomes:

The two homogeneous solutions for equation (1.2) are:

Find
Verify that when $$\displaystyle n=1 $$,

is true.

Solution
Substituting $$\displaystyle y $$ for $$\displaystyle x $$ in equation (1.2):

Substituting $$\displaystyle y $$ for $$\displaystyle \frac{x}{2}ln(\frac{1+x}{1-x}) $$ in equation (1.2):

Derive $$\displaystyle y^2_H = \frac{x}{2}ln(\frac{1+x}{1-x}) $$ to get its first and second order derivitives:

Substituting in equation (1.7):

So equation (1.5)is true.

=Problem 2.2 - Verify the Solution of an Equation=

Given
A differential equation:

Find
is the solution to equation (2.1).

Solution
Substituting $$\displaystyle p' $$ for (2.3) in equation (2.1):

End of proof.

=Problem 2.6-Show Linearly Independence=

Given
The two homogeneous solutions for equation (1.2) in problem 1.

Find
Show that the two solutions a linearly independent, and plot them.

Plotting
To make sense $$\displaystyle x $$ must be defined on the interval $$\displaystyle (-1,1) $$.

Plot $$\displaystyle y_{H}^{1} $$ and $$\displaystyle y_{H}^{2} $$. Matlab Code:

Proof of Linearly Independence
To prove linearly independence of $$\displaystyle y_{H}^{1} $$ and $$\displaystyle y_{H}^{2} $$ is to show that $$\displaystyle \forall \alpha \in \mathbb R, y_{H}^{1} \ne \alpha y_{H}^{2}$$.

That is $$\displaystyle \exists \hat x $$ such that $$\displaystyle y_{H}^{1}(\hat x) \ne \alpha y_{H}^{2}(\hat x) $$.

Take $$\displaystyle \alpha = 0 $$ for example.When $$\displaystyle \alpha = 0 $$, $$\displaystyle y_{H}^{1} = \alpha y_{H}^{2} $$ yields $$\displaystyle x=0 $$.

But when $$\displaystyle x=\frac{1}{2} $$, $$\displaystyle y_{H}^{1} \ne \alpha y_{H}^{2} $$.

So $$\displaystyle \forall \alpha \in \mathbb R, y_{H}^{1} \ne \alpha y_{H}^{2}$$.

User:Baminnick/enes100/poppit/cluster

Definition
A cluster can be defined as a group of balloons that follow these characteristics: 1. The balloons are directly next to each other (excluding diagonally) 2. The balloons have the same color

Significance
Ultimately, only a group of balloons or a cluster can be popped. Single balloons cannot be popped. Without popping balloons the game cannot be won.

Behavior
A cluster's classification can vary among any of the five colors. But by popping balloons, a cluster can be ruined because a part of the cluster will translate either vertically or horizontally. The movement of a cluster depends on the length of a row or column, and the likelihood of balloons in that row or column being popped.

Wikiversity talk:Candidates for Custodianship/Abd (full custodian)

Monitoring non-user votes
"Non-users" means users who come here just to vote on this CC, users who are not participating in Wikiversity. Since nobody is required to participate here, to consider someone a "non-user" isn't an accusation of anything, but this CC has been noticed, apparently, on Wikipedia and on Wikipedia Review, so users who are not paying attention to Wikiversity, but who have opinions from the past, may decide to come here to vote. Those votes will likely be based on "ancient history," not on my actual record as a probationary custodian. I'm seeing certain Oppose votes, but, strange thing, no actual opposition to any custodian action of mine appeared during the period, and, still, there is a deficiency of specific complaints. In some cases the origin and nature of those votes is quite easy to determine.

Users who are actually participating in Wikiversity have a different kind of interest. Non-users include users who believe that Wikiversity is hopeless, that it's useless to work here, and they have shown that through their non-participation. I urge them to reconsider, and to look more carefully at what has actually been happening on Wikiversity.

I need to look at this for my own information, because how I respond, personally, to this CC, will depend on whether or not I consider that it reflects the real Wikiversity community, or just those who are carrying grudges from the past. If there are errors here, please point them out. --Abd 02:14, 15 September 2011 (UTC)

Criterion for success at CC
I'd been thinking, based on a previous CC I had in mind, that I'd need to get some specific percentage of votes. That's not policy, the policy is different. Custodianship: Five days after the request has been listed, a bureaucrat will make the final decision based on the arguments provided in the discussion.

So if users are concerned about my possible permanent custodianship, they should provide arguments as to why this would be harmful. Evidence would help.

Aside from evidence, I would agree that there would be a harm from a distrusted custodian, but if the distrust is only coming from users who don't participate anyway, it would be of less significance. "I don't trust the user" coming from a user who is active building the project, who needs access to custodial support or fears custodial interference, would mean something. Coming from someone with non-project concerns, on the level of "I don't like him," or "He criticized me a year ago," it means something else. I've only been a probationary custodian for a bit over a month now, and so my use of custodial tools could not have been the reason why certain users were staying away. It's true that I've been active, very active, long term, even without being a custodian, but if that's a problem, it will not be resolved by my not being a custodian. I don't personally need the tools. It is merely a chance to serve.

I submit that I should be judged based on how I used the tools. I was not restrained, there were no actions that occurred to me that I did not take because I'd be facing an approval process. WYSIWYG. --Abd 22:46, 13 September 2011 (UTC)
 * Some of these so-called 'non-users' are currently not contributing for one reason only: your presence. Your habitual disqualification of other users is one of the main reasons why you should never be granted any kind of authority. You are a community destroyer. Guido den Broeder 23:24, 13 September 2011 (UTC)
 * Summary: "Some" is one, Guido den Broeder. He's telling the truth about himself. --Abd 14:25, 14 September 2011 (UTC)

 * How many is "some"? This could not be said about S Larctia and SalmonofDoubt. With respect to Ottava, "disqualification" of users would be completely unrelated to his decision to stop participating; at the time he went on sabbatical, he ascribed this to completing his dissertation. So that leaves Guido. He "retired" here, 15 August 2011. He withdrew his "offer" to be a custodian, the same day. He has 324 total edits here, most involved with contention in WV process, often contention with what he called my "silliness." (What I had stated was effectively policy, users are blocked for incivility. Look at my own block log! Right or wrong, I was blocked for incivility and I filed no complaint about the custodian who blocked. He erred as to specifics. So? Easily fixed. I have no trouble working with that custodian. No conflicts. Cooperation.)

 * Guido had only one edit after March 5, until placing that retirement notice. He likewise "retired" on meta, after casting a !vote to keep a user blocked. None of my activity here, nor the activity of anyone else, was preventing Guido from creating educational resources. Nothing on meta was preventing him from using meta for its purpose, to coordinate the projects. Reviewing his contributions globally, his position is clear. It's personal. He's likely telling the truth about himself. This issue of Wikiversity participation and how it relates to polls has been raised before. To understand the political situation read this discussion. Guido had the last word there, and the result was ... nothing. After seeing this happen a few times, after his custodianship bid went nowhere, he took his marbles home. That's his choice. He wasn't harassed, and he wasn't blocked or threatened with a block, he wasn't even close to something that would result in a block. On meta, it was different, but he still wasn't close to anything blockable this time.

 * As to "community destroyer," Wikiversity was seriously damaged in 2008, and again at the beginning of 2010, due to "meta intervention," in both cases by Jimbo (and that didn't work out well for Jimbo, either, he ended up resigning his most intrusive Founder tools after an RfC on meta started by a WV sysop over the 2010 incident.) What I've seen on WV, since I began working and helping here, and especially recently, reviewing Recent Changes, which I do daily, is a resurgence of educational resource activity. This is now obviously being considered a safe place to develop educational resources. The idea of closing Wikiversity has again been raised on my candidacy page. It's preposterous. I follow site closure decisions on meta. Wikiversity isn't close. We have been called the "Island of Banned Users." That's a good thing, not a bad one. Some of these users simply wanted to do things that could not legitimately be done on, say, Wikipedia, but which are actually useful here. Some encountered abuse elsewhere, but that's simply not our business. Some, it's true, will be disruptive anywhere, but this is a small minority. I'm a community builder, and it's the larger WMF community I'm building, by making and improving a place for educational activity here, which can help prevent disruption elsewhere. What JWSchmidt has called "Wikipedia disease" (which, translated into a more cogent criticism, just means the mentality involved in building an encyclopedia) sometimes leads Wikipedia users to think that what isn't proper on Wikipedia is "bad." And so they try to stop it from being expressed here. There were one or two sysops here who used their tools to support this exclusion. They are gone.

 * What continues to be enforced is the prevention of disruption by users attacking, here, users on other wikis. Or, often in the other direction, users from other wikis attacking users here based on behavior elsewhere. Often, these are personal grudges being brought and acted out here. It's not allowed, ultimately, and if local custodians don't handle it, stewards eventually will. So we do handle it. At least I do, and so do some other custodians, when they can. --Abd 14:25, 14 September 2011 (UTC)

 * A vote of oppose is not a personal attack. Guido den Broeder 08:30, 20 September 2011 (UTC)
 * That's correct, opposition is not attack. However, some expressions of oppositions include personal attacks. No specific accusation is made or implied. --Abd 18:07, 20 September 2011 (UTC)

Inactive or active
The classifying of users as inactive or active is improper for several reasons. First, one can have an interest and a stake in WV, but have to take off long periods when one is not participating a great deal. I, for example, am very busy with other issues but I also feel that real effort on WV might be wasting my time due to the way it is going. The presence of lots of editors who were banned on our prime site, wikipedia, does not encourage me. Second, no project run by the WMF should be seen in isolation. I have realized this by working hard for several years on my country's chapter, It is perfectly proper for people on other projects to come here. I did not come here just for this. I regularly check my watchlist here and comment if there seems a need. The attempt to divide the comments into those by "active" users which are OK and those by "inactive" users which are in a sense improper, is just one reason why Abd should not be a custodian. --Bduke 03:19, 20 September 2011 (UTC)
 * This is a classic wiki issue. If it were true that I was arousing opposition from a significant percentage of the active users, I'd really want to know that. To know, I must classify those commenting into active or inactive. Above is a rather arbitrary classification, and it is primarily for my own use. It's easy to check, that's why the contributions were listed.

 * The kind of data analysis represented by the above is actually an academic approach. The research question here is "Does position on Abd's custodianship correlate with Wikiversity activity?" Many other similar questions could be asked, and would be if I had time. There is data above, and this could be done much more rigorously. (I.e, with a clear, set-in-advance standard, or the data could be analyzed with many different standards.)

 * Yes, it is perfectly proper for users from other projects, or other inactive users, to come here and comment. What's a bit distressing to me is that Bduke seems to be claiming that I was opposed to such comments, or was impeaching them. Notice that among those I classify as "inactive" are users who supported me. In any case, this is probably all moot. The Wikiversity community knows how to seek and find broad consensus, and I'm proud to be a part of that. --Abd 18:18, 20 September 2011 (UTC)

Comments on the closure of the second vote

 * ❌ There is clearly not a consensus to promote Abd to full custodian. --SB_Johnny talk 10:06, 22 November 2011 (UTC)
 * Objection to closure by clearly involved bureaucrat, he should know better. Consensus is not clear in either direction, and discussion may be continued in such cases. In the prior voting, there was, among active Wikiversitans, a consensus for promotion, but such a close would have required considering activity, see my analysis on the Talk page. I would not object to a closure (whatever it is) by an uninvolved 'crat, or by Jtneill. Note that policy does allow me to continue as a probationary custodian, if there is a mentor. The prior compromise remains available; it was a unilateral withdrawal by SB Johnny that disrupted that compromise, and his misrepresentation at meta of the situation here that resulted in immediate desysopping. There was no emergency. I will pursue routine process for that problem. --Abd 16:05, 22 November 2011 (UTC)
 * There was clearly not a consensus to promote, which was the topic under discussion. If it were a close call, I would have hesitated to close it, but it wasn't a close call (no matter how you counted it). --SB_Johnny talk 16:37, 22 November 2011 (UTC)
 * May be true, but it's not your call to make, SBJ. You created the necessity for this vote by your out-of-process desysop, you're heavily involved, as review will show. As demonstrated before, "success" or "failure" are not the only possible closes. Sometimes extended voting time can be allowed, to get a broader sense of the community. My objection stands, and I request a neutral close, if any. --Abd 16:52, 22 November 2011 (UTC)
 * Yes, it's true, and it was my call to make (that's part of my "job", as they say). Sometimes extended voting is good, but only when it's a close call (this was more like a "snowball").
 * The vote is closed. --SB_Johnny talk 20:00, 22 November 2011 (UTC)

 * Comment on comment of Xijky. You may vote here and it is up to a closer whether or not to deprecate the vote. I have been a stand for the right of users banned or sanctioned elsewhere to make positive contributions here. Such users have included Ottava Rima and S Larctia ("Simone"), who opposed my candidacy. It's not surprising that some such users support my candidacy, because I opposed attempts to harass them here, this would include Marshallsumter and Poetlister, both of whom have extensive positive contributions as a result of my intervention. Perhaps the same personal characteristics that led to bans elsewhere lead some to oppose my work here, but I'll avoid applying this to individuals. It would involve judging their work elsewhere, which is precisely what I've been saying we should not do. Xijky, given that the facts don't support the thesis you assumed, did you preferentially check those who had supported me and not those who opposed? In any case, being banned on Wikipedia is correlated with being an expert in a field, happens all the time. Experts, amazingly, tend to "push their Point of View," and Administrator Randy from Boise doesn't like it, nor do his friends, if the POV happens to be unpopular and the expert unskillful or excessively persistent in the arcane world of Wikipedia governance. --Abd 16:33, 22 November 2011 (UTC)
 * Is there really any hard evidence to suggest such a correlation, anecdotally the vast majority of experts I have met editing wikimedia have not ever been blocked/banned. On the other hand the majority of people I have known to be blocked/banned I would not qualify as experts, this tends to make me doubt there is any real statistical correlation. Thenub314 18:33, 22 November 2011 (UTC)
 * I was going to say (partly) the same thing this morning: there are "WP Banned" people on both sides of the issue. --SB_Johnny talk 16:37, 22 November 2011 (UTC)
 * I just find it odd how Abd claims to have taken a stand for me when he was the one who actively sought to have me desysopped here and canvassed WR for support. I was also an admin here long before I received a 1 year ban at Wikipedia for non-academic/content related issues. I am also the only banned "expert" from Wikipedia to use Wikiversity. I never pushed my point of view at Wikipedia. Ottava Rima (talk) 18:38, 22 November 2011 (UTC)

 * It is a pity I did know about the voting. May be 6 days is too little period for closure? Fedosin 17:19, 22 November 2011 (UTC)
 * I've proposed that the minimum period be changed to 7 days, it's currently in policy as 5. Be that as it may, voting has lasted for much longer sometimes. See Candidates for Custodianship/AFriedman, which was opened Feb 5, 2010, until Mu301 closed with extended probationary status, commenting it is important that the community doesn't feel that the process is too rushed or that the candidates are not getting enough guidance in learning. My feeling is that it should be no big deal to extend a mentorship to give all wikiversity contributors an opportunity to get comfortable with the candidate and to allow plenty of time for the candidate to get a feel for when to use the tools in real world circumstances. The probationary period is extended for 4 weeks. Voting opened again March 28, and was not closed until June 9. The closure was by Jtneill, who was also the mentor.
 * What is largely invisible here is that at all times I've been subject to guidance from my mentor, who is that same Jtneill, a bureaucrat (originally my mentor was Draicone, but Draicone is on wikibreak), and also I've been subject to the Standard stop agreement, which allowed any custodian to order me to stop use of tools. I never violated that agreement, but was still "emergency" desysopped. There are a few users active and visible on this page who have interests in mind other than the welfare of Wikiversity, it is clear from their contributions, and there are others who don't take the time to research issues. Until and unless the community wakes up and addresses these issues, Wikiversity will continue to run on one cylinder.
 * Meanwhile, policy provides for continued probationary custodianship if a mentor consents. There is no consensus against this, which is what may allow Wikiversity to move beyond the dedicated opposition of what may be a minority faction, when it comes to those who are here to build the place. The 'crat SB Johnny refused to follow policy with my third probationary period, from the beginning, delaying it greatly, and he simply continued that opposition. --Abd 18:56, 22 November 2011 (UTC)
 * You mean 7, and that is standard. Also, there were very few supports from those who are active in this community. One was added after the user was banned by Abd himself. Even with another 10 votes in support from regular contributors he would have barely passed. Ottava Rima (talk) 18:30, 22 November 2011 (UTC)

Odd
Anyone else confused by Abd saying that it was a problem for SB Johnny to close yet it wouldn't be for Jtneill to do so? Jtneill was the first support, the first vote, the one who wanted Abd to become an admin against the wishes of every other regular, and has consistently been the lone voice in support of Abd. I think it is statements like that which is why Abd was so heavily opposed by the regulars here. Ottava Rima (talk) 20:16, 22 November 2011 (UTC)
 * I didn't say it wouldn't be a problem for Jtneill to close. I only said that I wouldn't oppose it, whichever way he closed. Someone else might oppose, and depending on the close, legitimately so. Generally, one may close, even if one has expressed an opinion, contrary to one's opinion. Not in favor of it, not normally, anyway. (There can be exceptions, but an exception that creates lasting controversy or divides the community, no, Bad Idea). I do wish that words would not be put in my mouth.
 * "Lone voice"? perhaps Ottava should actually read the discussion, and the one that preceded it. --Abd 20:38, 22 November 2011 (UTC)
 * Ottava's comment assumes that some particular vote is required. From the custodianship policy:
 * Five days after the request has been listed, a bureaucrat will make the final decision based on the arguments provided in the discussion. If you are approved, you will be a permanent custodian. If you are not approved, you are free to request another mentorship or withdraw your request.
 * The decision is, by policy, made by arguments, which would presumably include evidence. However, I've seen discussions closed on votes, disregarding policy, and it's a problem. Example: Candidates for Custodianship/Diego Grez was closed as failure by SBJ based on votes (66% he reported). There was at least one canvassed vote, from Abigor, with arguments that should have been irrelevant here. Another of the negatives was from a user who has opposed everyone, for a long time. I could show more examples of involved closes, as I recall, also from SBJ. Anyone can assess raw votes, but it takes discretion to consider arguments, and that's precisely why an involved close should not be allowed, not with the level of support shown for me on the candidacy page, in the two polls, and many issues (in both directions) of users without substantial contributions voting. --Abd 21:21, 22 November 2011 (UTC)

Email interview transcript
I emailed the Australian Profession Rodeo Association and Greyhound Racing Australia in regards to animal cruelty allegations affecting their organisations

My questioin
From: rhiannon stephens [mailto:rhiannonstephens1@hotmail.com] Sent: Thursday, 22 September 2011 3:12 PM To: admin Subject: Animal Cruelty Allegations

Hi

My name is Rhiannon Stephens and i am a student at the university of canberra studying sports management.

I am currently studying business, politics and sport.

As a part of this subject i am writing an essay about the effects that animal cruelty allegations have on sports that involve animals.

I was wondering if you would be able to give me some insight on how these allegations affect have on your organisation and how you deal with these issues?

Thankyou

Rhiannon

APRA
3/10/2011

Hi Rhiannon Unfortunately the sport of Rodeo does attract criticism from animal rights groups and individuals however as most of their comments are unfounded or are based on propaganda we don’t believe it has a major bearing particularly on people attending or participating in Rodeos.

Having said that the APRA is mindful of their presents and realised that the sport had to become more transparent and proactive if it was to survive under today’s expectations.

In the past 15 years rodeo policies and procedures have changed in regard to animal welfare. All our livestock contractors and rodeo judges must complete an animal welfare course and are under constant scrutiny. Statistics on livestock used and injured are recorded and in some states it is a requirement to forward them on to animal welfare regulatory authorities to cross check with their own records.

In 1992 the APRA introduced its own Code of Practice for the care and treatment of Livestock used in Rodeo. This voluntary code has since been adopted in part as standards or regulations in most states throughout Australia. APRA representatives sat on the National Consultative Committee for Animal Welfare (NCCAW) which was a National Government advisory group and now sits on Australian Animal Welfare Strategies (AAWS) (the current advisory group)

I hope this helps however of you require further information please contact me by telephone or email (phone number can be found below) Regards Steve Hilton General Manager

Hi Rhiannon,

Thanks for your enquiry – an interesting topic and one that we’ve been keeping our eyes on also.

Honestly, it hasn’t affected us at all. But that’s not to say it doesn’t have the potential to in the future when we look at what is happening to Greyhound Racing overseas. However, the key difference is that we put Animal Welfare at the heart of what we do. We employ an Animal Welfare Office whose job it is to ensure the welfare of the greyhounds before and during their racing career. We have partnered with both the University of South Australia and TAFE (Technical & Further Education) to ensure the dogs get the best in care and the students the best in vetinary and nursing education.

We also have the Greyhound Adoption Program SA (GAP SA) that places greyhounds in into foster homes so they can learn quickly how to be pets before finding them permanent new homes after their racing careers have finished. The condition for the dogs at our tracks are far better than that for their owners! The kennel blocks are all air-conditioned and each animal is vet checked before, and after the race, if required.

As greyhounds are doing what they love, running, and don’t have jockeys on their backs or hurdles to contend with, here in South Australia at least we’ve been pretty much free from animal cruelty allegations.

However, if allegations were directed towards the industry we’d investigate the claims thoroughly and would then decide next steps based on the outcome.

Does this help?

Cheers Rhiannon. Feel free to give me a call if you’ve any questions or would like further clarification.

Regards, Sam.

Essay Title: /Alcohol and Sport/

User:NHHowell/Alcohol and Sport

Alcohol and Sport have a long history together, dating back to the 16th Century when Britain's local pubs were the home of traditional sports such as bowls, cricket and wrestling matches.

Nowadays, sport has grown more dependent on alcohol, with alcohol companies being the major sponsors for most major sporting events and competitions, for example Victoria Bitter being the major sponsor for the NSW Blues in Rugby League and the Heineken Cup Rugby Union competition in the Northern Hemisphere. Alcohol is now a major source of revenue and business for sport.

However, as athlete issues with alcohol are becoming more prevalent, we are seeing sanctions handed down to them for their misbehaviour, such as Nate Myles’ recent sacking from the Sydney Roosters for breaking a team booze ban.

I will delve into the history of alcohol and sport and the common link that occurs between them now, and discuss the issue of how the majority of sports and clubs have major funding coming in from the sales and advertising of alcohol. I will discuss punishments handed down to athletes found to be abusing and misusing alcohol. I'm asking, how do clubs balance the interests of their sponsors, and the interests of their team and athletes in relation to alcohol?

Introduction
Picture the team or the athlete that your company sponsors winning a championship or individual honour one night, however the next morning all you can read about is their drunken antics of later that evening. Would these be people that you would be willing to have represent your company?

Athletes making the headlines for all the wrong reasons isn't necessarily a new concept, however as the years roll on the incidents seem to be increasing in number. Players struggle with being in the public spotlight as it is, however with alcohol companies' sponsoring more and more sporting teams and competitions, the temptation of alcohol is always in their face. Obviously as the drunken incidents occur, action must be taken by clubs and sponsors. Clubs lose sponsors and clubs cull players but how is a balance reached between placating sponsors and quenching the fan's thirst for success?

History
Britain saw a rise in the popularity of sport in the 16th Century when sport began to be tied into the local pubs. The publicans, in essence, became the worlds first sports promoters. They organised any sporting match, be it cricket, wrestling, bowls or boxing, and acted as a bookmaker so as to increase interest in the event. They even created events involving animals, such as cock fighting.

As time went on, alcohol's involvement in the development of sport only increased with Cricket's first publication in 1755 'New Articles of the Game of Cricket' making mention of the contribution of 'The Star and Garter in Pall Mall', a popular inn of the time.

Collins & Wray made mention in their Institute of Alcohol Studies paper 'Mud, Sweat and Beers: A Cultural History of Sport and Alcohol' of an Anglican vicar in 1893 stating that "Football is a fascination of the devil and a twin sister of the drink system." As such, it was already apparent by the end of the 19th Century that alcohol and sport often came hand in hand.

As time went on, Alcohol became synonymous with athletes. These are epitomised by stories such as the mystery man in the bowler hat, believed to be Johnny Raper, from the rugby league 1967 Kangaroo Tour whereby a player was seen walking the streets of England, drunk and wearing nothing but a bowler hat and bow tie. Another famous story is David Boon consuming 52 beers, confirmed by team mate Geoff Lawson, on the 1989 flight to compete for the Ashes in England.

Alcohol Sponsorship
As time goes on, alcohol sponsorship in sport is becoming increasingly prevalent. Most sporting teams or competitions now have an "official" drink, for example XXXX Bitter being referred to as the "Official beer of the Queensland Maroons" and the official NRL website stating "VB is the official beer of the National Rugby League, NSW Blues and naming rights partner of the VB Kangaroos. VB is also naming rights partner for the annual VB Test," and that's just rugby league!

Rugby Union has just as many, with competitions all over the world emblazoned with alcohol naming rights sponsors. For example, Europe's premier rugby competition is known as the Heineken Cup. The Northern Hemisphere's two other major competitions are also named after alcohol companies with the Magner's League (Ireland, Scotland, Wales) and the Guinness Premiership (England) following suit. The Australian national team, the Wallabies, has an 8 year relationship with Tooheys New, also listed on their website as their "official beer".

Motor sport also has its fair share of alcohol companies which sponsor teams. For example, Jack Daniel's, Jim Beam and Crown Royal all have teams within the NASCAR championship and Johnnie Walker has been a sponsor of McLaren since 2006. Johnnie Walker also sponsor golf tournaments, such as the Johnnie Walker Championship at Gleneagles and until 2009, the Johnnie Walker Classic.

Alcohol sponsorship even extends down to a local sporting level, with the premier Sydney rugby union competition known as the Tooheys New Shute Shield until the end of 2010. This required all clubs to have Tooheys New Logos printed on each sleeve of their jersey. Furthermore, the local Newcastle rugby league competition is known as the Tooheys New Cup.

Alcohol Sponsorship Issues
Issues have previously arisen due to competitions and teams being sponsored by alcohol companies. This is due to some countries, such as Ukraine, France and India, banning the use of alcohol advertising. As such, when a Heineken Cup match is played in France, it must be referred to as the "H Cup". The Welsh national rugby union team found the same problem from 2004-2010 when their major naming rights sponsor was Brains Brewery. Whenever they played in France, they had to change their sponsors name to "Brawn" so as to abide by the laws of their host nation.

In 2008, UK's The Telegraph reported "Beer and cider companies which sponsor sports clubs could be responsible for making Britain's binge drinking culture worse." It referred to studies conducted at Manchester University and Australia's University of Newcastle which found 46.7 per cent of alcohol sponsorship deals included deals for very cut price drinks for club insiders, including players and officials, at functions and during post match celebrations. Some of these deals even included free drinks! The study reported that athletes who compete for clubs with alcohol sponsors were more likely to binge drink. Dr Kerry O'Brien, of Manchester's School of Psychological Sciences, said of the study, "Sports people receiving direct alcohol-industry sponsorship of any kind, including payment of competition fees, costs for uniforms and the provision of alcohol beverages, reported more hazardous drinking than those not receiving sponsorship."

Grass Roots sport even has instances of cheap alcoholic beverages in certain situations. I can report that during the 2011 season, as a member of the Western Districts Lions u20s rugby union team in Canberra, I was offered nights out at the Academy Nightclub which included cheap drinks packages, free entry and the ability to skip to the front of the entry line. Is this really the treatment and message clubs, and sport as a whole, wants to send young athletes?

Sport needs alcohol revenue
Besides the fan's perspective of "What would the footy be if you were not able to have a beer while watching," revenue gained from alcohol companies keep many sporting teams afloat. Teams and competitions obtain an income not only from the aforementioned jersey and naming rights sponsorships but also from alcohol sales from within the events themselves.

Whilst there have been arguments against alcohol advertisements during sporting events or depicting athletes, sporting organisations are constantly fighting to justify the use of alcohol companies as sponsors. For example, in Brisbane's Courier Mail in 2009, Cricket Australia came out and said that eliminating alcohol sponsorship would lead to cuts in programs which facilitate active participation.

Triple M reported in 2009, the year the Australian Federal Government attempted to ban alcohol sponsorship in sport, that if alcohol sponsorships were banned, $300 million would be sucked out of the sporting economy. This would lead to clubs spending less on the grass roots level of sport and therefore the parents would have to pick up the cost. As such, registration costs would go through the roof which would ultimately lead to less kids playing sport. Is this really conducive to a healthy Australia or a successful sporting environment for a proud sporting nation like Australia?

Market analysts provided figures, for use in an alcohol sponsorship study conducted by Monash University, Deaking University and University of Western Sydney, that major alcohol companies spend up to 80 per cent of their advertising budgets on sporting events, competitions or teams. For example, in the US, alcohol companies spend $1 billion per year on advertising. Even if Australian companies spend only half of that, can we really afford to knock back $400 million worth of sponsorship?

Sports bosses have banded together in a bid to allow the continuation of alcohol sponsorship. AFL CEO Andrew Demetriou said "It would cripple football," and Cricket Australia spokesman Peter Young said "The danger with a simplistic approach like 'let's ban alcohol sponsorship of sport' is that all you do is significantly damage sport." NRL boss David Gallop concluded with "Our sponsors do a great deal of work promoting positive messages about responsible drinking and anyone who suggests sports could simply replace their support without substantial financial hardship is mistaken."

Player Misbehaviour and the need for success
It is no secret that the more successful your club is, the more sponsorship revenue you will receive. However, a question of how can you appropriately punish a player for an alcohol-related misdemeanor, yet still guarantee on-field success? It is something many clubs struggle with and often receive backlash for their decisions. With alcohol sponsorships and cheap alcohol constantly in front of them, it is near impossible to stop these alcohol related incidents occurring.

The most obvious example of this is Todd Carney. Carney has a detailed and well-known track record when it comes to drinking habits yet clubs continue to sign him. This is because when he concentrates solely on his rugby league, he is one of the best players in the world. This is evidenced by him winning the 2010 Dally M medal as the best player in the NRL for that season. As a recap, Todd has been in the news for:

 * Drink Driving (2006)
 * Drink Driving (2007)
 * Driving with a suspended license (2007)
 * Fleeing the scene (2007)
 * Urinated on a man in a Canberra nightclub (2008)
 * Sacked from the Canberra Raiders for not agreeing to a five point plan for rehabilitation (2008)
 * Vandalism (2009)
 * Fell from balcony (2010)
 * Drink driving (2011)
 * Broke team booze ban and subsequently sacked by Sydney Roosters (2011)

Does this sound like a man who you would want representing your club? The Cronulla Sharks certainly think so after they recently signed him for the 2012 and 2013 seasons. Therein lies the problem, how can he learn from his mistakes if he is not being punished? Here is a man with an obvious alcohol problem, yet he is still being contracted to play for teams on the basis that he is one of the best athletes available. This ties in to the need for success as Cronulla have existed for 44 years and still have not won a premiership. They are also a club on the brink of folding due to a lack of funding. As such, they have looked to Carney, a known alcoholic, for assistance.

Sponsors often don't want to be associated with clubs or athletes who provide bad publicity, for obvious reasons. For example, in 2005 the Transport Accident Commission ended a 16 year relationship with the Richmond football club after a young player, Jay Schulz, was caught drink driving. This resulted in the TAC terminating their major sponsorship and led to the sacking of Schulz. The TAC allowed their slogan "Drink Drive. Bloody Idiot" to be placed on the back of the Richmond jersey despite knowing the Tigers had an agreement with Peter Lehmann of the Barossa, a wine company.

Conclusion
Evidently a balance needs to be reached between sponsorship funds being made available to sporting competitions and teams. Currently, alcohol companies provide much of the income afforded to clubs. If the government is wanting to ban all funding, it must come up with a rich, viable alternative. At this stage, it is not plausible to ban alcohol advertising or sponsorship of sport. There is also no evidence to suggest such sponsorship increases binge drinking. However, all alcohol sponsors still convey a responsible drinking message when associated with sport. Therefore, it can be concluded that the alcohol sponsorship should be able to remain in its current capacity unless governments can replace or provide more funding to keep sport around Australia,and the world, alive.
