...HYDRAULICS LAB #1 The objective of this lab is to test the fluid flow provided by the power unit at various discharge pressures, and create a power unit characteristic curve. 1. Build on the trainer the hydraulic circuit shown in the figure below, using the components listed here. hydraulic power unit (2) pressure gauges flow control valve (FCV) – simulated load flow-meter Page 1 of 2 2. Initial setup: a. Fully close (CW) the FCV, and fully open (CCW) the pressure relief valve on the power unit. b. Start the power unit, and slowly adjust the pressure relief valve until pressure gauge P1 reaches 50 bar. Let the unit run for a few minutes then check and adjust P1 if necessary. c. Do not touch the pressure relief valve for the remainder of the lab. d. Fully open the FCV. 3. Test: a. Record the pressures P1, P2 and the flow rate under the “Min.” column in the table below. b. Slowly turn the FCV CW, adding a simulated load to the system. When the pressure at P1 increases to 15 bar, stop and record pressure P2 and the flow rate. c. Repeat for all columns listed in the table. The final column, listed as “Max Pres.” should be run with the FCV fully closed. Note the sound of the power unit during this test. You should detect changes in tone as the load (pressure) is increased. P1 Pressure (bar) P2 (bar) Flow Rate (lpm) Min * 15 20 25 30 35 40 45 46 47 48 49 Max.

...MIS 208 SPRING 2015 HOMEWORK 1 (due 13:15 on Monday, 6 April 2015, in class at 101) Reading Assignment: Please read section Duality and Sensitivity Analysis of the text book Winston. You will be responsible on that section in the exam. Question 1: Two different products, P1 and P2 can be manufactured by one or both of two different machines, M1 and M2. The unit processing time of either product on either machine is the same. The daily capacity of machine M1 is 200 units (of either P1 or P2, or a mixture of both) and the daily capacity of machine M2 is 250 units. The shop supervisor wants to balance the production schedule of the two machines such that the total number of units produced on one machine is within 5 units of the number produced on the other. The profit per unit of P1 is $10 and that P2 is $15. Set up the problem as an LP in equation form. Question 2: A company manufactures purses, shaving bags and backpacks. The construction includes leather and synthetics, leather being the scarce raw material. The production process requires two types of skilled labor: sewing and finishing. The following table gives the availability of the resources, their usage by the three products, and the profits per unit. a) Formulate the problem as a linear program and find the optimal solution by using appropriate Simplex Methods that you have seen in the class b) From the optimum solution determine the status of each resource.

...CHAPTER 15 Problem 1 Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. a) What is the mean or expected number of customers that will arrive in a five-minute period? The expected number is of 0.4*5 = 2 customer is a five-minute period. b) Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a five-minute period. The probabilities of the described scenarios are as follows: P0=20e-20! P0=0.135335283 P1=21e-21! P1=0.270670566 P2=22e-22! P2=0.270670566 P3=23e-23! P3=0.180447044 c) Delays are expected if more than three customers arrive during any five-minute period. What is the probability that delays will occur? This probability can be expressed as the probability of more than 3 customers arriving during the five-minute period, which can be computed as following: P(x > 3) = 1 – P(x ≤ 3) P (x > 3) = 1 – 0.85712346 P(x > 3) = 0.14287654 Thus, there is a 14, 29% probability of expected delays in five-minute period.

Know the stages of growth and development throughout the human lifespan 2. Understand the potential effects of life factors and events on the development of the individual 3. Understand the physical and psychological changes of ageing | Context | The study of lifespan development is about understanding the way we change over time. In this unit you will be able to identify some patterns in the course of human development and a range of factors that will influence how your life turns out. You will also need to make up your own mind about some very deep questions. Will you have a fixed life course where you can predict much of what will happen to you? How far is your life fixed for you by your genetics or by the social and economic environment you grow up in? How far can you choose to control your own life and can you try to ensure a happy old age? | Overall Scenario | As part of your work experience you have been asked to produce a fact file to show your understanding of the different life stages. You have been asked to discover as much information as possible about a family member (Parent, Aunt, Uncle, Grandparents) or a high profile person, to describe the stages of their life so far and what might happen in the future. | Task 1 Date issued | 17/11/15 | Task 1 Hand in...

Overhead is charged weekly at the rate of €1838 and 0.75 times direct cost.

Productivity Productivity is a measure of the rate at which outputs of goods and services are produced per unit of input (labor, capital, raw materials, etc.). It is calculated as the ratio of the amount of outputs produced to some measure of the amount of input used. Productivity = Quantity of goods and services produced Amount of resources used As the equation indicates, there are two variables in measuring productivity- the amount of production and amount of resources used. Productivity varies with the amount of production relative to the amount of resources used. Productivity can be increased in several ways, which Are given below here- 1. Increase production using the same or a smaller amount of resources. 2. Reduce the amount of resources used while keeping the same production or increasing it. 3. Allow the amount of resources used to increase c production increases more. 4. Allow production to decrease as long as...

...indifference curve and the budget line; (ii) a kink in an indifference curve; (iii) a “corner” where the consumer specializes in consuming just one good. Here is how you find a point of tangency if we are told the consumer’s utility function, the prices of both goods, and the consumer’s income. The budget line and an indifference curve are tangent at a point (x1 , x2 ) if they have the same slope at that point. Now the slope of an indifference curve at (x1 , x2 ) is the ratio −M U1 (x1 , x2 )/M U2 (x1 , x2 ). (This slope is also known as the marginal rate of substitution.) The slope of the budget line is −p1 /p2 . Therefore an indifference curve is tangent to the budget line at the point (x1 , x2 ) when M U1 (x1 , x2 )/M U2 (x1 , x2 ) = p1 /p2 . This gives us one equation in the two unknowns, x1 and x2 . If we hope to solve for the x’s, we need another equation. That other equation is the budget equation p1 x1 + p2 x2 = m. With these two equations you can solve for (x1 , x2 ).∗ Example: A consumer has the utility...
