Problem Statement
Supermarkets, at the end of the day, print out a long receipt that is a record of all purchases in the day. Normally, the receipts would be rolled up by hand, though this is a long and ineffective process. The receipts need to be rolled up faster and neatly, by way of some kind of mechanism.

Team Members

 * Zblaha2768
 * Nridings2
 * npsweet

Summary
The team started out by coming up with ideas. Zack made a lego mechanism that worked quite well, while both Nate and Nick worked on improvements to the design. The design would roll up the receipt tape using a crank to roll up the receipt. At week 3, Nate came up with a novel new design that worked significantly better than the lego version. The design and prototype construction was finished by the end of week 4.

Story
At the beginning of week 1, the team was unsure on how to proceed. Research on the topic of receipt rolling turned up nearly nothing, but Zack made a lego prototype of a potential design at around the beginning of week 2. Nick and Nate proceeded to come up with improvements to this design while Zack made improvements of his own. Problems in the design included the spool jumping as the crank is turned. To solve this problem, Zack made a "hook" to keep the roll from jumping upward. Nate and Nick created a tensioning device, which was successful in keeping the receipt in tension, but tended to crumple and rip the receipt as it was fed through. To remedy this, Nate took apart a printer and got a pair of rollers that would likely be significantly better than the lego version the mechanism was currently using. Nate, however, had created a successful motorized prototype at the end of week 3, and the team switched gears and began work on this newer, more successful prototype. By the end of week 4, the design was finished. This new design needs to be plugged into a wall socket to function, but is very effective at rolling up receipt tape.

Decision List
-Motor or crank

-Pursue a lego based design or build a prototype from scratch.

-Continue the current lego design or pursue new (promising) motorized design.

Material List
Original Design

-Lego Technic (various parts, from a snowmobile set # 8272, may not exist anymore)

-Receipt Spool

Motorized Design

-Motor

-Plywood (various size and shape).

-Button (on/off switch)

-outlet plug/wire

-Various lego pieces

Software List
Google chrome for research.

Time
16 hours

Tutorials
Make an assembly that allows for the receipt tape to enter straight, such as walls or a tensioner, to keep receipt from crumpling. Motorized mechanism is reconfigured, due to its simplicity. To make the motorized assembly:

solder an on/off switch to a motor and power source (battery or wall plug).

attach rolling assembly to motor.

The mechanism will roll up the tape quite effectively, however, may need some means of keeping the receipt tape straight for rolling.

Next Steps
The current mechanism needs to be miniaturized, and also needs to run on power from batteries rather than a wall socket. Materials should also not include legos.

Little research was done, however, there was plenty of prototype developing done.

Week1 Narrative
Spent some time working with Sweet on dismantling pieces of printer to use as a roller for the device. On my own, I spent some time building a potential prototype for the rolling/taut mechanism, but am missing some parts (rubberbands) so hopefully I can finish it once I get a hold of some rubberbands in class.

Week2 Narrative
I worked throughout the week to add more components to the lego mechanism. After getting general approval from my teammates, I set out to optimize certain parts of the lego assembly, specifically adding a crank and taking the tensioning part built by the other members of my team and attaching it to the mechanism.

Compare actual work done to Task3
Made improvements to design and implemented them accordingly.

Week3 Narrative
Expanded the walls on the tape purge by a couple of inches, to allow for the new mounting system (which involves locking the spool using lego cross nubs fitted into opposite sides of the spool, where there are small holes for them to fit into). Started testing of the rolling mechanism, works well though this is only when the roll is already partially rolled. For attaching the receipt paper to the spool from the start, used double-sided tape to start the rolling process. Unfortunately, due to either uneven receipt attaching or the mechanism acting differently under different stresses, the receipt rolls up unevenly, loosely and crumples along the walls. To remedy this I also added a rubberband loaded "hook" that springs on the roll and, theoretically, should keep the roll ight and maybe more even.

Spent less time on hook design, and more time on perfecting the new motorized system that Sweet made.

Week4 Narrative
Sweet made a new successful motorized design, so all work was diverted to that. I helped Sweet solder and contributed to the construction of the new system. Thursday was spent deciding on how we might advance the final assembly, though due to differing opinions, we moved on to different groups.

User talk:M.Finemore/Can Money Once Again Buy Success in the AFL

Matt, thanks for sending me your link to this essay. I think you have chosen a great topic. The approach you take is yours to choose ... just find the evidence you wish to use to argue your case. I noted recently that the AFL is looking at ways to boost the Football Departments of "unsuccessful" clubs. Do you think the game will have its own checks and balances?

User:EGM6321.F11.TEAM1.Prob R*4.3 Bens

=Problem R*4.3: Find $$\displaystyle m$$ and $$\displaystyle n$$ of the integrating factor $$\displaystyle H(x,y) = x^{m}y^{n} $$ such that the given N2-ODE is exact then solve for $$\displaystyle y(x)$$.=

Given
A function is given by

 * $$\displaystyle x^{m}y^{n} \lbrack \sqrt{x}y''+2xy'+3y \rbrack = 0$$

$$\displaystyle (1) p.21-3 $$

Per Lecture notes: [[media:pea1.f11.mtg21.djvu|Mtg 21 (c)]] where

 * $$\displaystyle h(x,y) = x^{m}y^{n}$$

$$\displaystyle (4.3.1) $$

Find
Part A: Find $$\displaystyle (m,n) $$ such that $$\displaystyle (1) p.21-3 $$ is exact.

Part B: Show that the first integral is a L1-ODE-VC and solve

 * $$\displaystyle \phi(x,y,p) = xp+(2x^{\frac{3}{2}}-1)y = k$$ $$\displaystyle (2)p.21-3

$$

for $$\displaystyle y(x)$$.

Solution

 * {| style="width:100%" border="0"

 * style="width:95%" |
 * style="width:95%" |

Part A:

The first exactness criteria for second order non-liner ODE is
 * $$\displaystyle F(x,y,p) = f(x,y,p)y'' + g(x,y,p) $$

$$\displaystyle (2) p.16-4 $$

where

 * $$\displaystyle p = y'$$

Comparing (1) p.21-3 with the form of (2) p.16-4, the functions $$\displaystyle f $$ and $$\displaystyle g $$ can be defined as

 * $$\displaystyle f(x,y,p)=x^{0.5+m}y^{n}$$$$\displaystyle (4.3.2) $$

 * $$\displaystyle g(x,y,p)=2x^{m+1}y^{n}p+3x^{m}y^{n+1}$$$$\displaystyle (4.3.3) $$

So the form of the 1st exactness condition is met.

For a second order non-liner ODE, the first part of the second exactness condition is
 * $$\displaystyle f_{xx} + 2pf_{xy} + p^2f_{yy} = g_{xp} + pg_{yp} - g_{y} $$$$\displaystyle (1) p.16-5 $$

For a second order non-liner ODE, the second part of the second exactness condition is
 * $$\displaystyle f_{xp} + pf_{yp} + 2f_{y} = g_{pp}$$$$\displaystyle (2) p.16-5 $$

Using the second part of the second exactness condition given above in $$\displaystyle (2) p.16-5 $$ and recognizing the given$$\displaystyle f(x,y,p) $$ from equation $$\displaystyle (4.3.2) $$  is not a function of $$\displaystyle p$$, so the first two terms are zero. Additionally $$\displaystyle g_p$$ is constant wrt. $$\displaystyle p$$ and therefore $$\displaystyle g_{pp}$$ is zero. $$\displaystyle (2) p.16-5 $$ can be simplified as shown below

 * $$\displaystyle 2f_y=g_{pp}=0$$$$\displaystyle (4.3.4)$$

Taking the derivative .wrt $$\displaystyle y $$ of $$\displaystyle f(x,y,p) = f_y $$ in equation $$\displaystyle (4.3.2) $$ and substituting into $$\displaystyle (4.3.4)$$ yields

 * $$\displaystyle 2\left[x^{0.5+m}ny^{n-1}\right]=0$$$$\displaystyle (4.3.5) $$

In order for equation $$\displaystyle (4.3.5) $$ to be true $$\displaystyle m=0$$

 * $$\displaystyle n=0$$$$\displaystyle (4.3.6) $$

For clarity we can now re-write equations $$\displaystyle (4.3.2) $$$$\displaystyle (4.3.3) $$ with $$\displaystyle n=0$$ as shown below:

 * $$\displaystyle f=x^{0.5+m}$$ $$\displaystyle (4.3.7) $$

 * $$\displaystyle g=2x^{m+1}p+3x^{m}y $$ $$\displaystyle (4.3.8) $$

Next, use the first part of the the second exactness condition given in equation $$\displaystyle (1) p.16-5  $$ with the following derivatives of $$\displaystyle f $$ and $$\displaystyle g $$ plugged in.

 * $$\displaystyle {f_{xx} = (m+0.5)(m-0.5)x^{-1.5+n}}$$

 * $$\displaystyle{f_{xy} = 0}$$

 * $$\displaystyle{f_{yy} = 0}$$

 * $$\displaystyle{g_{xp} = 2(m+1)x^{m}}$$

 * $$\displaystyle{g_{yp} = 0}$$

 * $$\displaystyle{g_y=3x^{m}}$$

Which yeilds:
 * $$\displaystyle(m+0.5)(m-0.5)x^{-1.5+m} = 2(m+1)x^{m}-3x^{m}$$ $$\displaystyle (4.3.9) $$

Solving this equation for $$ \displaystyle m $$ yields

 * $$ \displaystyle m = \frac{1}{2}$$ $$\displaystyle (4.3.10)$$

So the integrating factor to make $$\displaystyle (1) p.21-3 $$ exact is

 * $$\displaystyle h(x,y) = x^{0.5} $$
$$\displaystyle (4.3.11) $$

Part B:

So using the integrating factor found above and multiplying through to equation $$\displaystyle (1) p.21-3 $$ to get and exact N2-ODE one can use equation $$\displaystyle (3) p.16-5 $$ to obtain the first integral given in $$\displaystyle (2)p.21-3 $$

Rearranging equation $$\displaystyle (2)p.21-3 $$ and solving for $$\displaystyle y(x)$$ by dividing through by x to put the ODE into the general form:

 * $$ \displaystyle y' + a_0(x)y = b(x) $$
$$\displaystyle (3)p.11-3 $$

Yields:

 * $$ p + (2x^{\frac{1}{2}}-{\frac{1}{x}} )y=k $$

Where:
 * $$ a_o(x)=\frac{(2x^{\frac{3}{2}}-1)}{x}=2x^{\frac{1}{2}}-x^{-1}$$
$$\displaystyle (4.3.12) $$
 * $$ b(x)=\frac{k}{x}$$
$$\displaystyle (4.3.13) $$

The ODE can be solved by finding an integrating factor $$h(x,y)$$ per

 * $$h(x)=exp(\int a_o(x)dx)$$
$$\displaystyle (3)p.11-4 $$

 * $$y(x)= \frac{1}{h(x)}\int h(x)b(x)dx+C_1 $$
$$\displaystyle (1)p.11-5 $$

Substituting in $$h(x)=exp(\int a_o(x)dx)$$ gives:

 * $$y(x)=\frac{\int exp(\int a_0(x)dx)b(x)+C_1}{exp(\int a_0(x)dx)}$$
$$\displaystyle (4.3.14) $$

Integrating $$a_0(x)$$ which is given in $$\displaystyle (4.3.12) $$
 * $$\int a_0(x)dx=\int 2x^{\frac{1}{2}}-x^{-1}=\frac{4}{3}x^{\frac{3}{2}}-ln(x)+C_2$$
$$\displaystyle (4.3.15) $$

Plugging in $$\displaystyle (4.3.15) $$ and $$\displaystyle (4.3.13) $$ into $$\displaystyle (4.3.14) $$ yields:
 * $$y(x)=\frac{\int C_3x^{-1}exp(\frac{4}{3}x^{\frac{3}{2}})\frac{k}{x}+C_1}{ C_3x^{-1}exp(\frac{4}{3}x^{\frac{3}{2}})}$$
$$\displaystyle (4.3.16) $$

where $$C_3 = exp(C_2) $$

Equation $$\displaystyle (4.3.16) $$ is the solution for $$\displaystyle y(x) $$

Hey Alex, Your chapter is looking great and you have alot of helpful information! I also like your pictures. Just in time for Melbourne cup day next week! Jemmasanderson 05:50, 25 October 2011 (UTC)
 * Really informative so far, good job. The frequently used terms section leads nicely into discussed material. Under the heading 'pathological gambling', the middle paragraph is fairly long so maybe you could break it in two for a bit of an easier read? Otherwise, top stuff!AngeM 07:42, 23 October 2011 (UTC)

Looks great so far will you be discussing gender differences? If so did you know that the diagnostic criteria for gambling is also consistent with those with impulsive-compulsive buying disorder (ICBD) (Hartston, & Koran, 2002)? Except that females are more likely to shop and men are more likely to gamble. Miz.mira 05:29, 18 October 2011 (UTC)

Hey there! Interesting topic; it's great to see that you'll be addressing the multi-faceted nature of this issue. I think the section on pathological gambling is interesting, particularly the diagnostic criteria. I look forward to how you approach recreational gambling, and how intrinsic factors tie into pathological gambling disorders. What I found interesting in some of my own reading is that the gamblers often engage in the activity for the "high" or excitement involved, rather than concrete expectations of fiscal gain. It could be worth exploring in more detail the character attributes of people susceptible to this compulsive behaviour. Nice work man! Typify 09:38, 18 October 2011 (UTC)

Hey Alex. There was a great article in InPsych Magazine (Dec 2010) - a special report on the psychology of gambling. Are you able to source a copy? If not, email me at: tabitha.frew@defence.gov.au and I can copy it and send to you. Thanks :-) TabithaJ 09:36, 20 October 2011 (UTC)

Many thanks for your comments on my page Alex. Its a bit rough at the moment. I normally go through later and do a proof. Just concentrating on dumping stuff down. You might be interested in an interesting paper on EI and gambling Kaur, I., Schutte, N.S., & Thorsteinsson, E.B. (2006). Gambling control self-efficacy as a mediator of the effects of low emotional intelligence on problem gambling. Journal of Gambling Studies, 22, 405-411. Cheers,Ray U112052 00:03, 21 October 2011 (UTC)

Hey Alex. I've added in a text box for you. As far as changing the size, wait until you put some text in first and then see if the size needs changing. You'll see in edit mode, that I've annotated "insert text here" meaning you just need to type in that space, save it, and it should appear in the text box. If you would like to change the size of the box, you go into edit and find the formating for the box. Embedded in the formatting, you'll find a command which says says width (40%). You can change this to 50%, 60% etc, then save and preview. Keep increasing the number until it gets to the size that you want. Also, I was wondering with your glossary if you would be better to not have the actual terms as headings in the TOC? Rather, keep Glossary as a heading and then bold the key terms within that heading? Let me know if you'd like me to show you what I mean. It would just make the key terms stand out a bit more as a glossary. Thanks, TabithaJ 22:41, 22 October 2011 (UTC)

Hey Alex. Although I dropped the text box in for you, I took a guess in thinking you may not want them both to be bright yellow! I've changed one to blue, and the other one to silver. Please let me know if you would like different colours, or I can change it back. Alternatively, here is the link to Wikiversity colours: http://en.wikiversity.org/wiki/Help:Colors. Thanks, TabithaJ 03:22, 23 October 2011 (UTC)

Hi Alex, thanks very much for commenting on my page, that article is really helpful! Your page is looking great - good on you for making so much progress well in advance of the due date. I particularly like the idea of a glossary. To stay in line with the 'scientific self-help' theme, maybe you could include something at the end directing readers to services, or offering advice as to what they might be able to do to help themselves or those around them overcome a gambling problem. I think something along those lines would really be a great conclusion. Shauna ShaunaB 10:11, 25 October 2011 (UTC)

Hi there, I have a whole swag of journal articles on the subject of on-line gambling amongst 'college' (aka university aged) students. I'm not sure if you want to add anything new at this stage, but the on-line angle is topical in terms of the nature of this BC via Wikiversity. Anyway, on-line gambling among students is motivated by peer influences, to escape negative mood states, even 'fun' initially and of course instant positive reinforcements. If you are interested I can send you some more info. Crazydaisy 10:17, 26 October 2011 (UTC)Crazydaisy

Hi Alex, It looks great and the content hits the mark. Thankyou for the inspiration, I now know I need to put in more work

Hi Alex, your chapter is really interesting and looks great. I noticed you have mentioned gambling in older adults, research has shown there is a distinct subgroup of late start older adults. Noticed also you have recommend Eudaimonic book chapter, no doubt environmental mastery would apply to gambling. (Susann 20:21, 1 November 2011 (UTC))

Thanks Alex for your comment. Well done on your chapter, Im still needing more words not less. Regards, (Susann 23:31, 1 November 2011 (UTC))

Your chapter is looking great. It makes my uploaded content so far look bad. The layout is nice and simple, which I like and makes it easy to read. Not overloaded with pictures or extra materials that tend to take away from the content. I'm glad I finally got around to looking at your chapter. Michelle.n 12:38, 3 November 2011 (UTC)

Very nice! I very much like the way you included the diagnostic criteria for pathological gambling. Well done! Jackson997 04:37, 6 November 2011 (UTC)

Draft feedback
Well done on getting a full draft together. Some suggestions - take, leave, or follow-up on any of them as you see fit: Sincerely, James -- Jtneill - Talk - c 00:10, 26 October 2011 (UTC)
 * 1) Glossary: Move the glossary into a subpage Motivation and emotion/Book/Gambling/Glossary since it doesn't really help to engage the reader or answer the problem question. You might also wish to combine/acknowledge the previous gambling chapter's glossary where appropriate: Motivation_and_emotion/Textbook/Motivation/Gambling
 * 2) Introduction: Engaging and interesting. Maybe work more on setting up the problem to be solved - e.g., how to healthily engage with risk-taking through gambling whilst avoiding its potential pitfalls?
 * 3) Social Implications of Gambling: Long paragraph - consider splitting it. Explain how this section relates back to the practical life problem/challenge being investigated. I only skim-read this paragraph, but based on the conclusion, I'm concerned that it looks like a bit of a rant.
 * 4) Recreational Gambling (RG) - What is RG? (explain). Long para - consider splitting it. Ideally, express one idea per paragraph in three to five sentences. Sentence 1 links to the previous para and explains the idea. Middle sentences expand on the idea. Last sentence concluded the idea and sets up a link to the next para.
 * 5) Pathological Gambling (PG) - Source of testimonial (if its yourself, I think this should be explained)? I guess I'd be looking in this section for clear identification of signs and symptoms of PG, the risk factors (who is vulnerable) and what can be done at a psychosocial level to help mitigate the potential for PG. This is a long section, but on quick skim-read appears to fulfill these functions.
 * 6) Gambling in older adults + Gambling in adolescents - Maybe these two short sections could be brought together under a heading e.g., Gambling through the lifespan - or integrated into the previous section
 * 7) Risk - My sense is that risk-taking / sensation seeking / BIS/BAS etc. could be brought up into the Intro or a section immediately after in which the underlying psychological need to engage in novel, challenging, risky situations is explained. Then gambling can be considered as one of the ways in which we seek optimal arousal/stimulation. At the moment, I think the main theoretical proposition is based on intrinsic-extrinsic motivation. This could work too (although I am not familiar with this literature on I-E motivation and gambling), but I think it needs at the very least to be considered in relation to risk-taking. Basically, explain up front to the reader the problem/opportunity of gambling, a theoretical explanation of the risk-taking (gambling) instinct), and then look at examples of healthy gambling (RG?) and problematic gambling - when things don't have limits and get out of control.
 * 8) Summary - This hits the kind of mark, the book is looking for I think.
 * 9) Cross-word - if you want to do this it probably wouldn't take up wordcount - e.g., it can go on a sub-page. It is good if you're trying to each a glossary of terms. But there might be other activities which more actively engage the reader in the chapter's key goals/points.

Hi Alex You have done a great job. The reference list is fantastic. I have a bit of work ahead of me to be up toyour standard. u990911

Hi Alex, Great choice and integration of images throughout the text. I particularly like the Melbourne cup racing scene (which would be especially relatable at the moment!) and The Gambler, which is quite an emotive portrayal of gambling.

It must be a relief to have more words available now that you have moved your glossary. I am happy it is still available to refer to and reflect upon terms while reading through the chapter content. However, I'm not sure what the red circle is about next to extrinsic motivation in 'Extrinsic Motivation, Intrinsic Motivation and What's the Difference?'

You have taken an interesting approach to the chapter by focusing on the intrinsic/extrinsic distinction for gambling motivation. Within this approach, you could discuss how people might adjust their own problem gambling behaviour through influencing exposure to extrinsic motivators, cues etc. (how people might overcome impulses to gamble by managing incentives and consequences might be relevant?) A lot of the content seems to be descriptive and it might be worth including more prescriptive advice or self-help alongside this detail.

Being a statistician, I am quite excited to see that you have included prevalence rates!

Try to avoid one-sentence paragraphs, as in Pathological Gambling, 'Research on differences...'

In Pathological Gambling, 'women are more likely to gamble on EGM'? What's EGM? electronic gambling machines? You may like to acronym this when you first refer to it in full at the start of your chapter.

I like your inclusion of the diagnostic criteria for pathological gambling in a separate feature box and how you draw attention to this in the text as a means of self-assessment and awareness of problem gambling behaviours. Drawing attention to awareness as the first step, then providing readers with a means of seeking help through CBT, Gamblers Ananymous and helplines is great and consistent with the self-help objective for the book. I also think the way you link to resouces at the end is a fantastic way for interested people to seek help!

I appreciate your discussion of risk, which could potentially be expanded to include more on risk-taking. Here, you might like to discuss the individual differences that predispose people to gambling. For example, people with a low level of arousal may seek out activities like gambling in order to achieve a level of stimulation and arousal that inactivity does not provide, as research suggests that excitement/arousal motivates gambling more than financial incentive (Reeve, 2009, p. 380). This could draw in a conversation around sensation seeking and acceptable, less risky alternatives that these people could substitute to achieve a similar level of arousal. However, given your comments on the SS scale in the tutorial, I can understand if you are aversive to including this content! Also, I appreciate that you have already mentioned and worked these concepts throughout the chapter - you have clearly included quite a breadth of applicable research!

I enjoyed your learning quiz at the end of the chapter, although when I first glanced at it I wasn't sure if it was a quiz for determining risk-taking predisposition or assessing learning. Perhaps include a descriptive title: Quiz - Assess your learning, understanding, Learning Quiz, or something similar.

Please take or leave any of my comments as you see fit. You have developed a unique chapter and it is clear you have effortfully engaged with the topic. Congratulations on progressing to this stage so early and good luck with the final touches! I look forward to seeing you again and hearing your ideas at the last topic on growth psychology.

= R*5.1 2nd Exactness Condition For n=2 Case of Nn-ODE (Method 2) =

Given
Equivalent form of 2nd Exactness Condition for N2-ODEs :

 * {| style="width:100%" border="0" align="left"

$$
 * $$g_0-\frac{dg_1}{dx}+\frac{d^2g_2}{dx^2}=0$$
 * $$\displaystyle (Equation\;4.7.1)
 * $$\displaystyle (Equation\;4.7.1)
 * }
 * }

Coefficient equalities, located in previous reference above.

 * $$\displaystyle g_0=f_yq+g_y$$

 * $$\displaystyle g_1=f_pq+g_p$$

 * $$\displaystyle g_2=f$$

Note also that $$\displaystyle p(x):=y'(x)$$ and $$\displaystyle q(x):=y''(x).$$

== Find ==

Show the following equality is true:

 * $$\displaystyle f_{xx}+2pf_{xy}+p^2f_{yy}-g_{xp}-pg_{yp}+g_y+\left( f_{xp}+pf_{yp}+2f_y-g_{pp}\right)q=0$$

Solution
Applying the chain rule to $$\frac{dg_1}{dx}$$ yields the following:

$$\frac{dg_1}{dx}=\frac{\partial g_1}{\partial x}+\frac{\partial g_1}{\partial y}\frac{dy}{dx}+\frac{\partial g_1}{\partial y^{(1)}}\frac{dy^{(1)}}{dx}$$

We know what $$\displaystyle g_1$$ is defined to be, we can substitute in $$\displaystyle p(x):=y'(x)$$ and $$\displaystyle q(x):=y''(x)$$ and carry out the derivatives:

$$\frac{dg_1}{dx}=\frac{\partial g_1}{\partial x}+\frac{\partial g_1}{\partial y}p+\frac{\partial g_1}{\partial p}q$$

$$\frac{dg_1}{dx}=\left(f_{xp}q+g_{xp}\right)+\left(f_{yp}q+g_{yp}\right)p+\left(f_{pp}+g_{pp}\right)q$$

We can apply the same approach to $$\frac{d^2g_2}{dx^2}$$ :

$$\frac{d^2g_2}{dx^2}=\frac{\partial^2 g_2}{\partial x^2}+\frac{\partial^2 g_2}{\partial y\partial x}\frac{dy}{dx}+\frac{\partial^2 g_2}{\partial x\partial y}\frac{dy}{dx}+\frac{\partial^2 g_2}{\partial x\partial y^{(1)}}\frac{dy^{(1)}}{dx}+\frac{\partial^2 g_2}{\partial y^{(1)}\partial x}\frac{dy^{(1)}}{dx}+\frac{\partial^2 g_2}{\partial^2 y}\frac{dy^2}{dx^2}$$

$$\frac{d^2g_2}{dx^2}=f_{xx}+f_{yx}p+f_{xy}p+f_{xp}q+f_{px}q+f_{yy}p^2$$

Adding $$\displaystyle g_0 $$, $$\displaystyle \frac{dg_1}{dx}$$ , and $$\displaystyle \frac{d^2g_2}{dx^2}$$ according to Equation 4.7.1 yields our final solution:

$$ g_0-\frac{dg_1}{dx}+\frac{d^2g_2}{dx^2}=\left(f_yq+g_y\right)-\left(f_{xp}q+g_{xp}+f_{yp}pq+g_{yp}p+g_{pp}q\right)+\left(f_{xx}+f_{yy}p^2+2f_{xy}p+2f_{xp}q\right)=0$$

Talk:Motivation and emotion/Book/2011/Growth through adversity

Comments
Jude, I think your chapter looks and reads fantastically! To tie in with our 'self-help' theme, my only suggestion at this point would be to include something on how people turn trauma into an opportunity for growth - what motivates them? what makes one person more likely to use trauma for personal growth than the next? You could possibly include some examples e.g. someone experices sexual abuse and through the recovery process is able to rebuild a lost connection with family members. I look forward to reading the finished product! ShaunaB 04:25, 19 October 2011 (UTC)

Hi Jude. Thanks for your kind comments on my page :-) Yours looks beautiful! I really love the Tree of Life picture, and the quote. It gives your page a feeling of emotional depth. I was wondering about the concept of rumination. It was really interesting to read that rumination can be positive, as I'd always associated it with a negative. Specifically, I remember reading a few articles about how women in particular are prone to negative rumination. This could be something to consider for your page; i.e. when to know if the rumination is becoming negative and harmful? Anyway, just a thought. Keep going - your page looks amazing! TabithaJ 22:49, 22 October 2011 (UTC)

Hey Jude. I've added some of your suggestions to my "relationships and happiness" page - I've added a text box with a story (about Michelle) and also in my intro I've tried to make my languaging a little more "self-help-ish". Just wondering if you would mind having a quick look when you get a chance to tell me if you think it's ok? Thanks :-) TabithaJ 05:47, 23 October 2011 (UTC)

Hi, your chapter is amazing well done-  I know that you already have an example but I found another example Stephen Hawking on wiki. He is very inspirational. Good luck with your chapter in progress Miz.mira 09:11, 25 October 2011 (UTC)

Hi, I love your chapter. I have just been reading an book chapter on Optimism and the content of your page ties in beautifully with that theme. Well doneCrazydaisy 05:57, 2 November 2011 (UTC)

And... just noticed your referencing in your first para (Triplett et al., 2011) - should the first ref be all authors' names in full, then et al for following in txt refs? Also, Triplett spelling is incorrect at end of first para + no et al (you can tell I'm grasping at straws for something to comment on!!)Crazydaisy 06:04, 2 November 2011 (UTC)

I'm really impressed by your book chapter, very intersting and fantastic pictures. (Susann 12:15, 2 November 2011 (UTC))

Draft comments
I've had a quick look - here's some comments: Sincerely, James -- Jtneill - Talk - c 07:33, 2 November 2011 (UTC)
 * Overall - Great job, these is coming together really well - the structure, depth, tone, content is all looking solid, so these suggestions are relatively minor
 * Check APA style for citation formatting e.g.,, et al. -> et al.
 * Frankl: A key point from Man's Search for Meaning is that Frankl wondered why some survived and some didn't in the concentration camps - he observed and came to understand that those for whom the experience had meaning and purpose were more likely to find the will to survive (and therefore more likely to survive).
 * Sense of Coherence - Antovosky - this is a closely related concept from a contemporary (or a little later) of Frankl's - and warrants consideration
 * PTGI - Revise this to more clearly address: What does it measure? (e.g., The extent to which personal growth occurred following a traumatic experience?) How many factors are there? What are they? (e.g., Maybe a summary table of factors and definitions). Which items relate to which factors? Or are these 10 items measuring one overall factor?
 * Nick Vujicic - Could provide a link to youtube video of Nick
 * Move the meaning making section with Armstrong quote to the Summary or Conclusion section. Move the quote so that you finish the chapter in your own words.

Multimedia
Jude - your multimedia is great! It's so well spoken - you have such a friendly voice! Well done!!! ShaunaB 06:10, 13 November 2011 (UTC)

Talk:Motivation and emotion/Book/2011/Toxic workplace

Comments
Hello Magnolia, I am writing the page on Emotional Intlligence, but I have also had more than a passing interest in psychopaths in the workplace and done some research which might be useful for your page. Two papers spring to mind- Managing Psychoipathic Employees by Mitchell Langbert and Corporate Psychop[aths and Organisational type by Clive Boddy. Both are recently (2010) and both are available through the Ucan Search function on the library page. Hope this helps. Regards Ray 58.169.42.158 06:24, 19 October 2011 (UTC) By the way, the above post suggesting a couple of papers to help your web page was me, Ray. I forgot to log in so here is my proper sgnatureU112052 06:38, 19 October 2011 (UTC)

Headings
Note that in the document you sent me, the headings were not created using styles (Heading 1, Heading 2, etc.) so these have not come through as wiki headings. You would need to edit these in yourself as per Help:Headings. -- Jtneill - Talk - c 22:37, 3 November 2011 (UTC)

Subtitle and focus questions
I recommend developing a specific subtitle and introducing some focus questions in the Introduction which clearly identify the goals of the chapter. These goals should clearly relate back to motivation and emotion self-help book theme. -- Jtneill - Talk - c 22:44, 3 November 2011 (UTC)

Emphasis
The second half of the current draft seems to drift into bullet-point lists and legal information. In redrafting, I'd recommending reducing this emphasis and instead emphasising relevant psychological theory and research about the emotional impact of bullying and what can be done about it from a psychosocial point of view, with pointers towards how further support can be obtained. -- Jtneill - Talk - c 22:50, 3 November 2011 (UTC)

Talk:Motivation and emotion/Book/2011/Self-regulation of overeating

Comments
Hi there, looking like a practical and useful guide so far. Possible further areas to include if you need them:

 * - How overexposure to food in the media influences overeating, along with social factors (eating alone or with company)
 * - I also remember how James mentioned in a lecture that dieting increases ghrelin levels (hunger messengers) and can induce binge eating.

All the best & looking forward to reading it! - Jaybay 06:27, 19 October 2011 (UTC)

Hey there. I really like your topic and your page so far. It looks like you've made sure to cover off on the "how to stop overeating" stuff which is great. I was wondering if you plan to include something about fad diets and why they don't work? Good work on your page :-) TabithaJ 09:33, 20 October 2011 (UTC)

Looking really good. Also I've seen some stuff on boredom and overeating and I remember reading somewhere that behaviors such as watching tv or eating while at your desk condition your mind to feel hungry when doing those things. So every time I eat at my desk, the next time I sit down I am conditioning myself to get hungry. EamesA 02:05, 26 October 2011 (UTC)

HI Clair, I am very passionaite about healthy eating and promoting the cause ;).A possible concept you could bring up when talking about tips on food control is in relation to leptin and high satiety foods. for example, fats and protien digest slower than carbohydrates. therefore this contributes to longer periods of satiety, influencing leptin, which decreases food seeking behaviour. one could argue that a diet high in the two macro nutrients could promote negative feed back signals, decreasing evereating due to longer periods of satiety.Lucas K 23:41, 26 October 2011 (UTC)

Hey Claremw I was just wondering if you were happy for me to put your page in the topic as apart of my "See Also" section? I am discussing eating from an emotional perspective rather than motivational. Thanks, your chapter is looking great so far!! Ashleetronerud 27 October 2011 (UTC)

Hi Clair, Thanks for the reply. Yes, as you suggested, fat does slow gastric emptying, and its incompatibility with water restrains its digestion more so than carbs. Fats are KJ dense therefore half the portion of food is needed for the same energy output. nevertheless, promoting fats for dietary benifit could SCARE the public LOL! Lucas K1 10:29, 27 October 2011 (UTC)

Hey, good job so far! I agree with JayBay, in that i'd like to read about the influence of social factors on eating. I guess for a lot of people eating is a big part of the social world, and it would be good to know what effect this has on eating habits. You could maybe even talk about how people eat differently with different social groups, i.e. when i'm with my family I eat whatever I want, but when with people I don't know so well, I tend to not eat so much. Might be getting a bit too in depth, haha, but just a suggestion! Tashc 10:04, 3 November 2011 (UTC)

Hi there! Just a little thing which you probably already know. Please correct me if I'm wrong but there should be a comma after the name and before the year in the 'bracketed' citations. E.g. (Smith, 2011), (Smith & Jones, 2011) etc. Your work is coming along really well though! HarryMMM 23:13, 3 November 2011 (UTC) - Hey HarryMMM thanks for your comment. I am hoping to put all my references in as foot notes anyway so those in text references are really just place holders. i appreciate the in put tho- Keep it coming lol Claremw 23:47, 3 November 2011 (UTC)

Hi there, looks like you page is right on track it looks great :). I really enjoyed your final section on conflicting standards.Trinand 11:26, 4 November 2011 (UTC)

hey there I really like the pictures you have on your page, they do look apetising, would it be interesting to find out how overeating can be related to obesity? Shanti 11:35, 4 November 2011 (UTC)

Hi Clair, so sorry for the late reply, but thanks so much for your comments on my topic. Yes sure, I would be more than happy to link our chapters -- make sure I do it right, otherwise feel free to edit it in, as I am not exactly a Wikiversity expert .;) good luck with the final editing!!!

Hey there! A very appetising chapter! Made me hungry! I really enjoyed your chapter and felt I could relate to some of the "take home" messages you were referring to. Being a university student, I agree that socialising makes you gain weight! There is always somewhere new to try out! Good job on your chapter! SKM1501 07:32, 07 November 2011 (UTC)

Hello and welcome to the user page of Will Gladstone!!! I am rather pleased to come in Wikiversity I am eager to communicate with other editors of Wikiversity so that I can get a few tips on editing and creating new articles.

I like electronics,mathematics,engineering and theoretical physics.I am interested in evolution and genetics,too.

Information on electronics
Electronics is the branch of science, engineering and technology that deals with electrical circuits involving active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and is usually applied to information and signal processing. Similarly, the ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a working system.

Electronics is distinct from electrical and electro-mechanical science and technology, which deals with the generation, distribution, switching, storage and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays, transformers, resistors and other passive components. This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers and vacuum tubes.

Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This section focuses on engineering aspects of electronics.

Information on theoretical physics
The advancement of science depends in general on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigor while giving little weight to experiments and observations. For example, while developing special relativity, Albert Einstein was concerned with the Lorentz transformation which left Maxwell's equations invariant, but was apparently uninterested in the Michelson-Morley experiment on Earth's drift through a luminiferous ether. On the other hand, Einstein was awarded the Nobel Prize for explaining the photoelectric effect, previously an experimental result lacking a theoretical formulation.

Problem Statement
How can we build an electric go kart with old car batteries and two forklift motors?

"When you look at the problems associated with batteries, you gain a different perspective on gasoline. Two gallons of gasoline, which weighs 15 pounds, costs $3.00 and takes 30 seconds to pour into the tank, is equivalent to 1,000 pounds of lead-acid batteries that cost $2,000 and take four hours to recharge." How Stuff Works Article

Summary
Put an overall, one paragraph summary here with links to the team weekly reports.

Poster
Put a graphic in wikimedia, include the graphic here or link to it here. The graphic should be suitable for creating a traditional project poster.

Story
Tell a story of the project. Describe how split up, what the obstacles were, what testing was done, what informal decisions were made, what assumptions were made, what the results were. This is a longer version of the summary with links to all the details collected associated with the project. These links could be to software, links to videos, links to project pages with pictures, etc. Think of the story as a summary of the team weekly reports on one long page rather than a short paragraph like the summary.

Decision List
List all formal decisions made with links to their documentation such as a decision tree or decision matrix.

Material List
Figuring out what to purchase, what to build, what everything costs is a huge part of engineering. Typically there is a list of materials in stock, materials that are ordered, materials that should be ordered next time there is money, materials that have not been fully justified. These issues are part of healthy management of the engineering lab but are associated with a particular college. The detail needs to be published in this "Done" form. However in the project root, just a list of materials is necessary.

Software List
Installing and learning different software packages is part of most engineering project just like the materials list.

Time
Time estimates and actual time consumed measurements helps justify salaries (grades). The only way to gain respect for estimated project time and costs is to practice.

Tutorials
Most projects consist of making instructions to jump start the next team, shrink the learning of tools and software to the minimum, advice on where to purchase materials, how to assemble, etc. Tutorials modified or created are described here with links.

Next Steps
If this is not filled out, the next team may have to repeat each of your steps just to figure out what the next step is. It is best to write this immediately at the end of the project while creating the summary, poster, presentation, and story.

Subjective Critera
While reading these sections, practicing engineers are building up the following impressions about the document. So the following categories are more subjective:

Repeatablitly
Is there enough detail to repeat the work?

Integrity
Proving something doesn't exist or doesn't work usually requires exhaustion. Simply saying "it can not be done" is like challenging a pro basketball player (engineer) to one-on-one basketball (find a solution). It does not inspire respect. All the different ways respect is created can be found throughout the wikibook General Engineering Introduction.

User:Egm6321.f11.team1.zheng.zx/personal place/HW4

= R*4.6 Show the equivalence of two forms of 2nd exactness condition of N2-ODE =

Given
$$ \displaystyle g_0 - \frac{d}{dx}g_1+\frac{d^2}{dx^2}g_2=0 $$

$$ \displaystyle g_i:=\frac{\partial G}{\partial y^{(i)}} \, \quad for \ i=0,1,2 $$

Find
It's equal to the 2nd exactness condition in form:

$$ \displaystyle \phi_{xy}=\phi_{yx}\ ,\quad \phi_{px}=\phi_{xp}\ ,\quad \phi_{py}=\phi_{yp} $$

Solution
As defined:

$$ \displaystyle G=\frac{d \phi}{dx} (x,y,p)=0 $$

$$ \displaystyle G=\phi_x+\phi_y \cdot p +\phi_p \cdot q $$

$$ \displaystyle for \quad p=y' \, \ q=y'' $$

$$ \displaystyle g_0 = \frac{\partial G}{\partial y} = \frac{\partial}{\partial y}(\phi_x+\phi_yp+\phi_pq) = \frac{\partial}{\partial y}(\frac{d \phi}{dx}) $$

$$ \displaystyle \frac{d}{dx}g_1 = \frac{d}{dx}(\frac{\partial G}{\partial p}) = \frac{d}{dx}(\phi_{xp}+\phi_{yp}p+\phi_y+\phi_{pp}q) $$

$$ \displaystyle \begin{align} \frac{d^2}{dx^2} g_2& = \frac{d^2}{dx^2}(\frac{\partial G}{\partial q})\\ &=\frac{d^2}{dx^2} [\frac{\partial}{\partial q}(\phi_x + \phi_yp +\phi_pq)] \\ &= \frac{d^2}{dx^2} \phi_p\\ &= \frac{d}{dx}(\phi_{px}+\phi_{py}p+\phi_{pp}q) \end{align} $$

For we have:

$$ \displaystyle g_0-\frac{d}{dx}g_1+\frac{d^2}{dx^2}g_2=0 $$

$$ \displaystyle \frac{\partial}{\partial y}(\frac{d \phi}{dx}) - \frac{d}{dx}(\phi_{xp}+\phi_{yp}p+\phi_y+\phi_{pp}q) + \frac{d}{dx}(\phi_{px}+\phi_{py}p+\phi_{pp}q) = 0 $$

Rearranging:
 * {| style="width:100%" border="0" align="left"

\displaystyle [\frac{\partial}{\partial y} (\frac{d\phi}{dx})-\frac{d}{dx}(\frac{\partial \phi}{\partial y})] + \frac{d}{dx} [(\phi_{px}-\phi_{xp})+(\phi_{py}-\phi_{yp})p+(\phi_{pp}-\phi_{pp})q] = 0 $$ $$
 * $$\displaystyle (Equation\;4.6.1 )
 * }
 * }

So, both two parts in the left side of equation 4.6.1 are equal to 0 separately: For first part:

$$ \displaystyle \frac{\partial}{\partial y} (\frac{d\phi}{dx})-\frac{d}{dx}(\frac{\partial \phi}{\partial y})=0 $$

$$ \displaystyle (\phi_{xy}-\phi_{yx})+(\phi_{yy}-\phi_{yy})p+(\phi_{py}-\phi_{yp}q)=0 $$

so:

$$ \displaystyle \phi_{xy}=\phi_{yx} $$

$$ \displaystyle \phi_{py}=\phi_{yp} $$

And, second part:

$$ \displaystyle \frac{d}{dx} [(\phi_{px}-\phi_{xp})+(\phi_{py}-\phi_{yp})p+(\phi_{pp}-\phi_{pp})q] = 0 $$

$$ \displaystyle (\phi_{px}-\phi_{xp})+(\phi_{py}-\phi_{yp})p+(\phi_{pp}-\phi_{pp})q = 0 $$

thus we get:

$$ \displaystyle \phi_{px}=\phi_{xp} $$

Weather station/Wireless

Wireless weather stations can be a real bonus when you wish to understand trending weather patterns. Personally, I've owned one wireless weather station for over two years now.

I've learned many great things with this wonderful device, one being that I can pretty accurately predict the weather just by watching the trending barametric pressure. What will normally happen is that the pressure will drop, then rise within about a 12 hour period.

Once the wireless weather station shows a dropping barometric pressure that dips much lower then before, then I know that we are in for a great storm. Time to lock down the hatches.

This only came through time and experience. I do find this procedure to be more than 90% accurate. There are times when the weather will be tricky but, most of the time, it comes through.

What really helps is a shifting wind pattern, too. Watching wind speed allows me to guess how fast the changing weather pattern is emerging in my area. Winds over 20km/hr will normally indicate a real weather shift.

I personally would recommend purchasing your own wireless weather station if you wish to learn much about how weather operates.

Here's another tidbit for you. Weather will move into an area in waves, much like a tide coming in or out. We especially witness this effect right here in sunny Alberta.

Engineering Projects/Rubberband gun/Howard Community College/fall2011/501 Rubberman

Problem Statement
Our goal here is to create a working gatling gun that fires rubber bands as ammunition. It needs to be fully automatic and very similar to its military counterpart.

Team Members

 * Fahad
 * Charles
 * Mderrick
 * Corey

Summary
We just got the project of making this gun. The biggest issues in the previous teams were that the gun had a problem getting stuck and not actually shooting rubber bands. We made a design that will eliminate those problems and is a very simple yet effective plan to make this gun with as less issues as possible. we had intinally gone with the same design as the previous team, but decided to change the design as we realized soon into the project that it was a bad idea. we decided to go with the idea of a gun like the disintegrator http://www.youtube.com/watch?v=0GAUnuuBkW4

Story
We started out thinking this will be a easy project looking at many designs and going with the one we thought was the best one. we started to construct the project and soon figured out that it is much harder than it looks as we faced many difficulties. We had initially assumed that the design we chose, a cardbord cylinder would be perfect for it. Thinking about its light weight and already round shape we decided to build the gun of the cardboard cylinder. Then later we fell into sea of troubles, From finding the right materials, getting the materials in time. We had to spend a lot of time trying to get the measurements of pegs we need the pcv pipe we need. The barrel would be made out of cardboard. Then ordering the materials was the easy part. Getting the materials 3 weeks into to the project was very disapointing. especially since we only have about 4 weeks to do this project. Then when we got the materials, we started to make holes into the barrel to get the pegs to fit in. Then we ran into a problem of the cardboard becoming very week with every hole we made. We decided to not make so many pegs in the barrel for the support purposes. When we got the pegs we set them on top of the shleves in the work shop and when we returned, we had lost more than half of our pegs. We were only left with 12 of them. We then decided to just go with what we have and continue the project. We then just started putting the support in for the barrel. we used cutters to cut the paint rollers in the middle and attched the barrel onto it and then we found The barrel was not spinning smoothly. So putting that issue aside we started finding a motor for the barrel to spin and unfortunately couldnt find any in time. Not finding the right motor to spin the barrel was hard. The barrel being to fragile to handle all the force of the rubberbands and all the cutting and constructions required. As we approached the end of this project we realized that we werent going to complete it. We are going to continue this project but with a different design.

Decision List

 * 1.We decided to go with the design which uses the string to release the rubber band. we found it more effective and a simpler design.
 * 2. We are going to be using cardboard cylinder to be the barrel
 * 3. We are going to be using paint rollers to be the support for this gun
 * 4. We decided to carry on this idea even though we ran into some trouble
 * 5. We arent going to finish this gun, so are continuing this project

Material List

 * 1. Large cardboard tube
 * 2. Small PVC pipe piece
 * 3. String (any size string would work)
 * 4. Paint rollers x3
 * 5. Small wooden pegs
 * 6. Cordless battery powered drill
 * 7. Rubber bands (as ammo)

Software List
We have used no software for this project, and we see no further application of software in the future of the project.

Time
In class is always there, but most of the time for this project was spent outside of class. The group decided to do indiviual work as it seemed to best fit everyones schedule. All of our team members spent more than 4 hours a week working on this project.

Tutorials

 * BEFORE YOU BEGING TO FOLLOW THIS TUTORIAL. NOTE WE DID NOT SUCCEED IN MAKING THIS GUN.
 * 1. Start out getting a good solid, light cylinder base for the barrel.
 * 2. Start by getting the wodden pegs and cuttin every 4 pegs 3/8" less then the previoius size
 * 3. Start marking holes on the barrel for the pegs
 * 4. Drill the holes in the barrel
 * 5. Start putting in the pegs starting from the tallest one on the first row
 * 6. Used Gorilla glue to glue down the pegs
 * 7. Cut the pain rollers in the middle
 * 8. Bend the paint rollers stokes up at 90 degrees
 * 9. Cut notches to the end of the barrel of where the stokes of the pain roller would fit into.
 * 10. This is as far as we got and faced many problems along the way. follow tutorial with caution.

Next Steps
Try to get a good motor in first before anything. Use a better design. The design we used was full of problems. Get the barrel to be a lot stronger. DO NOT USE A CARDBOARD CYLINDER FOR THE BARREL. Get a better support for the barrel to spin freely. We thing the best way would be to use bearings. Good luck to the next team.

1000 Songs/All creatures of our God and King (Francis of Assisi)

All creatures of our God and King (Francis of Assisi)

1000 Songs

Text
Originally from Canticle of the Sun, this is a literal translation of the text directly from the Canticle of the Sun.

Author
The author of this text is Francis of Assisi who lived from 1181-1226. He was born into a wealthy family, but after an illness at the age of 25, he was convicted to give lavishly to the poor and forsake worldly pleasures. One aspect of this was that he lived in solitude for a year in a cave. He had a great deal of respect for nature and animals.

Translations/Challenges
Paraphrased by William H. Draper (1855-1933). Draper set the words to the 17th Century German hymn tune "Lasst Uns Erfreuen", for use at a children's choir festival some time between 1899 and 1919. For text as translated by Draper and a recording set to the "Lasst Uns Erfreuen" tune, click here.

Tune
The first tune this song was put to was "Lasst Uns Erfreuen," but it is also used in several contemporary worship settings today. These are primarily by David Crowder, and by the worship band Third Day, who does a version along with Jennifer Knapp and Nichole Nordeman. This is called Sing Alleluia. It has a lot more momentum, but it lacks the rich harmonies present in the hymn version.

Editor's Choice
I personally prefer the hymn as translated by Draper and the tune that he set it to, but I think that if I were to use this text in a modern worship setting, it would be much more effective to use one of the more contemporary versions.

Cultural setting
This text reflects the mentality of the author and shows that while he values life and creation, he has a full understanding of God's ultimate sovereignty.

Give instructor top 3 project choice list
I decided to stay assigned to the Rubber Band Gun project.

This week we started to develop our own rubber band gun designs while continuing work on our original model.

Write problem statement
I have been assigned the task of building a gatling-gun style rubber band gun. This rubber band gun must fire rubber bands at a high rate from a rotating barrel driven by a motor.

Assign Task0
For week 0 my assignment was to find potential components for the trigger assembly of the gatling style rubber band gun.

Compare actual work done to Task1
This week I found and purchased a 10-count trigger set on www.rubberbandguns.com. They should arrive later this week.

Week1 Narrative
This week I designed a barrel assembly for the chamber, which will contain the trigger and sprocket, as well as the barrel, which will have a notched end to retain the rubberbands for launch. The designs will become more size specific when I receive the rubber bands and triggers.

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 a signature ~ by entering four tildes in a row to create a time and date stamp. Create a new category if another team mate has already commented here.

Assign Task2
For this upcoming week I will determine how much wood I will need and where I will order it from so I may start the construction of the rubber band gun.

Compare actual work done to Task2
I have determined that I will need two sheets of plywood, 8 ft. of 1/4" dowel, and 8 ft. of 3/4" dowel. I will need the plywood to build the frame, the 1/4" dowel to build parts within the trigger assembly, and 3/4" dowel to build the length of the barrel. I will be ordering these parts from TW Perry.

Week2 Narrative
This week I build a preliminary chamber setup using 1/4" dowels, 1/4"x6x2 poplar planks, a sprocket and trigger from trigger set, and a 5/16" dowel. First, I cut the plank into two 5 1/2"x7" planks. Then I drilled three 1/4" holes into one plank at the following locations: 7/16" from the top and 3 5/16" from the right side, 7/8" from the top and 1 29/32" from the right side, and 7/16" from the top and 1 1/4" from the right side. I then drilled mirrored holes on the second plank. I inserted 3 - 1/4" dowels through the holes of one plank. I then inserted the trigger on the middle dowel and the sprocket on the most centered dowel, leaving the far right dowel (closest to the corner) without a trigger piece so it may reflect the trigger back into it's starting position. Then I placed two 1/2" spacers on the front and back of the plank. Once those steps were completed, I sandwiched it all with the second plank by lining it up with the appropriate 1/4" holes. Lastly, I attached a notched 7 3/4" - 5/16" dowel on top of the forward spacer by using a rubber band. Currently, the whole chamber assembly is held together by three rubber bands. Permanent fixture is required for proper operation.

Assign Task3
This week I will build as many more firing chambers as the amount of wood I have will allow. I'm aiming for 10 firing chambers total. Once I have the chambers built I'm going to mount them to 3 wooden discs to complete the barrel and prepare it to mount onto a drill motor.

I used a miter saw and table saw to cut the poplar planks/dowels down to form the firing chambers.

Week3 Narrative
This week I cut the poplar planks down to 6"x2" rectangles and used the drilling template to drill uniform holes through all the planks. I also cut the dowels down to 1" pieces to insert into the drilled holes to hold the trigger assembly in between two planks (chamber walls). I ran into a dangerous problem this week with using the saw. I tried making small 1" spacers using the left over wood from the cut planks with the miter saw. Using the miter saw caused the wood to explode and splinter. So I abandoned trying to use the miter saw and opted for a table saw instead. The table saw caused a very similar explosion of wood pieces when I tried to cut. So I abandoned the table saw as well for a small hand saw although, it was very time consuming. I would recommend using a standup ban saw because the thin blade would cut the small pieces of wood without fear of splintering, splitting or explosion. I successfully built six firing chambers. The next step is to cut three discs of wood and six 5/16" dowels to mount the firing chambers into a barrel.

Week4 Narrative
This week I completed the chamber assembly to the rubber band gun. First, I measured out 3 6-inch hexagons on a piece of 3/8" CDX pine plywood using 120 degree angles that were determined using Pythagorean Theorem. Next, I used a table saw to cut them out. The table saw is the reason I chose the hexagon shape as it is near impossible to cut a well rounded circle using a table saw. A circular shape is very much preferred and I would recommend using a ban saw in place of a table saw. After cutting the hexagons I drilled a hole through the center of all three of them using a hand drill with a 3/8" drill bit.

Once the hexagons were complete, I moved on to glue them to the front and rear ends of the firing chambers I made last week. Unfortunately, the dimensions of the six chambers were all different. This is because it is extremely difficult to cut small wood into precise dimensions using a table saw. Again, for this step, I would recommend using a ban saw for a more uniform fit. So the hexagons did not fit flush against the chambers due to the uneven sizes. To rectify the problem, I attempted evening them out using a hand saw. This was time consuming and not very effective. I opted to not attempt the table saw again due to risk of wood explosion, splintering, and splitting because of the small size of the wood. So I decided it would be best to just move forward with the project as best as I was able. I applied wood glue to the front and rear ends of the firing chambers and attached the hexagons as evenly as possible. The fit was uneven and disproportionate and the assembly needs to be replaced with better cut wood supplies.

Next I used a piece of 3/8" all-threaded rod that I purchased from | Lowe's to thread through the center 3/8" holes drilled earlier. After threading the rod through the center of the chamber assembly I used two nuts on the front and rear of the chamber assembly to hold the rod and chamber in place. The inward pressure of the two nuts also presses the wood together to allow for the wood glue to dry more effectively.
