A VIDEO that you create where you teach your peers how to factor

What to do:

1. Create/find your own example (different from the lectures notes and video examples) of each of the different types of factoring below:

   • Factoring by grouping (See the Appendix D Part One Video 2 from 10/13 materials found here (Links to an external site.))

   • Factoring a trinomial with leading coefficient 1 (See the Appendix D Part One Video 3 from 10/13 materials found here (Links to an external site.))

   • Factoring a trinomial using the ac-method (See the Appendix D Part Two Video 1 from 10/14 materials found here (Links to an external site.))

   • Factoring a difference of squares (See the Appendix D Part Three Video from 10/15 materials found here (Links to an external site.))

2. Record a video of yourself explaining the details – step by step – of how to factor each of these 4 different types. You will need to demonstrate/illustrate each step of the work so that your peers can see the work in the video; it can’t just be audio.

3. Conclude by giving reminders of things that you’ve learned along the way (e.g. when should you use each type, “don’t forget to…..”, etc.)

1. Snaps Graph

In class, we saw an example of a snaps graph, for the continuous flow exercise. The graph illustrates the system state over time. The graph allows one to “read off” the answer to pretty much any question that is posed.

1. Produce a snaps graph, that indicates over time the snaps present in each stage of the process. (You can use the graph shown in class as a model, but do not feel you have to reproduce it; there are many useful visuals that one could create.) The graph can be neatly hand-drawn (take a photo) or done in software.

2. Write out the calculations for all “transition points” in the graph. Make them easy to read. Indicate units. The calculations can be handwritten (take a photo) or typed out. Excel is NOT expected here.

3. Process Improvement – Bins

The most snaps in the receiving bins is 175 barrels. So it is obvious that increasing the bin size by 175 (to 400 barrels) will eliminate the waiting of trucks.

Is 400 barrels the smallest receiving bin capacity, such that trucks don’t have to wait? Briefly justify your answer.

3. Process Improvement – Delivery Break

One idea for improvement is this:  Take a “delivery break” during the day to let the plant “catch up”. During the delivery break, trucks will not arrive. After the delivery break, trucks will resume at the same arrival rate as before. The same total quantity of snaps will be delivered.

1. What would be the metrics to evaluate a plan for a delivery break?

2. Propose a good plan for a delivery break.

3. Quantify the performance of your plan.

Use an optimization model to determine the best course of action for your real estate company, using the following assumptions:

You wish to maximize the net present value of profit over the next eight quarters. Assume 6% IRR, compounding quarterly. (so 1.5% per quarter)

In each neighborhood in which they open an office, they will achieve a baseline of 5.5% market penetration, and earn a 5% commission on sales. For every .1% the commission you charge decreases, your market penetration will increase by .15%, (down to a minimum of 4% or a maximum of 5%)

You must pay rent and utilities in each office you open each month. Determine the average cost per gross square foot of commercial real estate in your neighborhood for the last year (in NYC Historical). [When determining this value, you should exclude properties where gross square feet or sale price is unknown.]  Each month you will pay 1.5% of this for rent and utilities for each square foot of office space you rent. You must rent at least 250 square feet of office space, plus 125 for each employee you hire.

You may hire up to 3 employees. Each employee you hire costs a yearly salary $65,000 including benefits, and increases your market penetration by .5%.

Your monthly operating budget is $15,000.

Create a game like a dice game that 2-4 players can join in which a player can do 3 attempts if they do not like their first. after all players done their attempts or picked to stay with their first or second attempt then the player with highest score wins. This can can be played by real players or player vs computer. Or a card game similar to that.
Requirements:

1. Create proposal describing what the program will do. need within a day or two.

2. Create 3 status reports.

4. Draft report.

5. Final report.

2. Using the geometric method determine the amount of excavation required for the basement in below Figure 2. The basement measurements are from the outside of the foundation walls. The average depth of the excavation is 7 feet. The footings extend 1 foot outside of the foundation walls, and a 2-foot space between the footing and the sides of the excavation must be provided to form the footings. The soil is excavated at a 1.5:1 (horizontal:vertical) slope. Express your answer in cubic yards.

3. The perimeter of the floor system in below Figure 3 sits on a redwood sill. Determine the number of 16-foot-long pieces of redwood that are needed to complete the floor system. Determine the materials needed to construct the joists and joist headers for the floor system. An engineered rim board is used for the joist headers. Determine the number of 4-foot by 8-foot sheets of 23/32 T&G OSB sheathing that are needed to construct the floor system.

4. Using a waste factor of 8 percent, determine the number of cubic yards of concrete needed to pour and the amount of rebar needed for two of the spread footings in below Figure 4. Allow for two inches of cover.

5. Determine the number of modular bricks needed and labour hours for the wall in below Figure 5. Assume that 675 bricks are required for 100 square feet of wall. Add 4 percent for waste.

EGRE 303 Lab 3: PN Junction Lab – Exploring PN Junction Diode

Project Goal:
Your task in this laboratory project to explore and understand operation of PN junction diodes and gain insight
into some limitation associated with a simplified the textbook model. The simulation tool is available at
Nanohub. (nanohub.org).
We have discussed in class the depletion approximation. The depletion approximation is extremely useful, when
it is valid, so it is important to understand its limitations. In this work, you will compare the results of depletion
approximation analyses of PN junctions with the “exact” solution obtained by solving the semiconductor
equations directly by numerical simulation using the computer program.

Part 1: Analytical calculations with the depletion approximation:
1) A Si step junction maintained at room temperature under equilibrium conditions has a
p-side doping density of NA = 2 x 1015 /cm3
and an n-side doping of ND = 1015/cm3.

EGRE 303 Lab 3: PN Junction Lab – Exploring PN Junction Diode

Use the depletion approximation to compute:
(a) Vbi
(b) The depletion layer boundaries, xp, xn, and the depletion width, W
(c) The electric field at the junction.
(d) The electrostatic potential at the junction.
(e) Plot of the charge density, electric field, and electrostatic potential as a function of position, as well as I-V
characteristics.
2) Repeat problem 1), still using the depletion approximation, but set the p-side doping to NA
= 3 x 1017
/cm3
and keep the n-side doping at ND = 1016
/cm3
. Compute the same quantities
as in problem 1) and compare the results to those of problem 1).
Part 2: “Exact” numerical simulations and their comparison with “textbook” result:
Set the doping densities on the P and N sides of the junction to correspond to those in problem 1) above.
Set the length of the P-region to be 1.0 micrometer and for the N-region, 2.0 micrometers. Be sure that you have
selected “Si” as the material and that the temperature is “300K.”
Simulate the parameters of the defined structure .
3a) Use the potential vs. position plot to determine the built-in potential of the PN junction. Compare your
answer to the depletion approximation result. (Remember that potentials always have an arbitrary reference, so
don’t be confused by the fact that the potential is not zero on one side of the junction.)
3b) Use the carrier density vs. position plot to estimate the width of the depletion layers on the P and N sides, xp
and xn. First, plot side-by-side the carrier density vs. position assumed in the depletion approximation and the
numerically generated plot, then determine whether the depletion approximation results are reasonable. Explain

KNH 184: Assignment 6 – Measurement of Motor Learning and Performance

*Before attempting Assignment 6, you should thoroughly review Module 6.2 Measurement of Motor Learning.

Using Excel or another suitable graphing software, create a properly labeled chart including performance curves, retention interval and retention tests for the data presented below, and then answer these two questions.

1) Which group of softball players improved fielding performance the most during the 10-week practice phase?

2) Which group of softball players exhibited superior learning of fielding?

KNH 184: Assignment 6 – Measurement of Motor Learning and Performance

Fielding = to catch or pick up the ball after it has been hit in a game such as baseball or softball

Two groups of softball players practiced fielding for 10 weeks with each group using a different practice technique. At the end of each week, all players’ fielding performance was tested using a 50-trial fielding test. The data below reflects the average number of errors made on the fielding tests by each group. RI = 10-week retention interval; RT = a 50-trial fielding retention rest.
