...Ayer Keroh, 76100 Melaka, Malaysia ___________________________________________________________________________ Abstract This report discussed the effect of workstation design, assembly design, jig design and working posture on the assembly of plugs. Two different designs of jig (vertical and rectangular) and two sets of assembly line design (one and two operators) and two set of workstations design (sitting and standing) were studied to observe their effects to productivity. Design of Experiments 23 with two levels of each factor is used to conduct an experiment for obtaining the most productive jig and assembly line design. Two groups of workers were employed to assemble the plug in 8 different ways. Number of replication is 32 for each setting and total of electric plugs produced by each group is 256 units. The results shows that jig design have the most significant effect to the assembly time. Furthermore, the other factors: assembly design and workstation design are also show significant factors to assembly time. However, interaction combinations of two or three factors were not significant to assembly time. The most productive assembly line design which achieved the lowest assembly time is the combination of one operator, with rectangular jig and work station design sitting. Meanwhile the working posture of workstation design that provides the lowest RULA score was sitting position, it provided score 2 which is safe. © 2011 Jordan Journal of Mechanical and Industrial...

...Two-Career Family Versus One-Career Family My paper will focus on the differences and the similarities between the two career families and one career families, and will give ideas regarding which of the two is better in the development of the individual career. There are various studies that focus on the career development of the individual and how the work is connected with the non-work lives of people. There are divergent studies that show the strong relationship of family and work. It shows that the developmental needs of the family will produce incomplete understanding regarding the career dynamics (Arthur & Hall 1989, p. 159). One of the main differences between the two career family and the one career family is the focus on the roles and the responsibilities of the parents, concerning the many needs of the family. The one career family is what we call the traditional setup, where the male’s major task is to be the financial provider and have great influence over them. Men primarily handles the decision-making process, while the women assumes the responsibility of taking care of the home, caring and raising the kids, managing household chores, cooking, and handling day-to-day errands. Some of the one career families focus on the fact that some men place a lot of heart and attention on their own career, whereas, family time is considered a secondary responsibility. On the other hand, the two career family is considered the product of evolution, and the development...

...paper was prepared by me specifically for this course. Student's Signature: ______________________________ ***************************************************************** Instructor's Grade on Assignment: Instructor's Comments: Executive Summary ZZ Airlines is currently deciding whether or not to hire an additional Call Service Representative. The airline does not want the wait time in the call center, between midnight and 6 A.M, to be more than 3 to 4 minutes, in order to provide good customer service. Additionally, the airline is planning to do an advertising campaign which is expected to increase the number of callers, based on similar past campaigns. Based on the statistical simulations, and its subsequent results, an analysis will determine whether an additional Call Service Representative is needed. Background Recently ZZ Airlines opened its doors as a commuter service, with its headquarters and hub located in a regional center. A product of airline deregulation, it joined a number of short-haul, point-to-point airlines, that have been successful. ZZ was started and managed by two pilots. It acquired a fleet of twelve used propjet planes and airport gates vacated by Sprint...

...order to induce an electromotive force. The EMF was measured as the magnet fell. The integral of EMF versus time gives the magnetic flux according to Faraday’s Law of induction. Faraday’s law of induction essential states that EMF is equal to the rate of change of magnetic flux. Some aspects of Lenz’s law were also investigated. Lenz’s law states that the direction of the current in a coil moves in the direction that causes a magnetic field that opposes the change in the magnetic field of the magnet. Procedure and Materials: The computer was set up by connecting the Voltage Sensor and the interface. A new activity was opened in Data Studio with a graph of Voltage versus Time. Automatic recording was set to begin recording once 0.05 volts was reached and stop at 0.4 seconds of elapsed time. The alligator clips were connected to the circuit board springs next to the induction coil. Data was recorded for three variations of the experiment. First, a single bar magnet was dropped through the coil starting with the south end approximately 2 cm above the coil. Then two magnets were dropped with their south ended taped together. Finally, two magnets were dropped with the south end of one magnet taped to the north end of the other. The integral of each peak on the graph was recorded in Table 1. Results: Voltage versus Time Figure 1. This graph shows voltage versus time of the three separate runs. The box in the top right gives the color coding for each line. The integral of each...

...It was clear that during run number 1, many problems existed. Changes made to the simulation for run number two of the paper airplane factory were implemented as a means of combatting the chaotic atmosphere that were present during run number one. These changes are listed as follows. Workstations one through four were relocated to one table. Signal cards were placed on the table after each workstation. The foreman was no longer part of the simulation, and the paper stock inventory was relocated to a position right beside workstation one on the table. Batch sizes were reduced to just one unit. The same work instruction was used for each operation just as in run number one. The material handler was in charge of moving one batch from the inventory...

...Memorandum To: Cynthia Crowninsheild From: Date: 2/22/2014 Re: Production Analysis SHUZWORLD A. Distribution Pattern Shuzworld has three plants that ship units to three central warehouses. The company would like to know the lowest transportation cost monthly along with the best shipping plan to achieve the lowest cost. To analyze the cost we are using the transportation modeling tool. The optimal cost is $13,400 which would be the lowest monthly transportation costs which is shown below. Transportation modeling is the best tool to use as it finds the lowest optimal costs when shipping products from several plants to several different destinations. Our model shows three different plants of Shanghai, Shuzworld H, and Shuzworld F with three different warehouses. The individual unit costs to ship from each plant to each warehouse is entered in order to calculate the optimal cost. Also shown below is a shipping list whish details the exact amounts that should be shipped from each plant to each warehouse in order to achieve the optimal costs shown. This would be the best distribution pattern to use in order to achieve the optimal costs. The patterns show any demand constraints and also meets availability while minimizing total shipping costs. Looking at the shipping list chart the increased production from 1300 to 2800 units caused the supply to exceed the demand which is shown in the Dummy row ( dummy destination at no cost) that way the cost figures...

...Research 1. What are two alternate recipes for Senate Bean Soup? Senate bean soup is a standard item on the Senate restaurant’s daily menu. Although the origins of this culinary decree has been lost in antiquity, It is said that Senate bean soup has become a tradition based on a request of Senator Fred Dubois of Idaho who served in the Senate from 1901 to 1907 and sat as chairman of the committee that supervised the Senate Restaurant. The traditional recipe includes mashed potatoes, while later versions had replaced the mashed potatoes for braised onions the more recent versions does not include either. Listed below are two alternate more recent versions of Senate Bean Soup. Ingredients for the first recipe include: Six ounces of dried navy beans Forty fluid ounces of chicken stock One-half smoked ham hock Vegetable oil as needed Two ounces of diced onion Two ounces of diced carrots Two ounces of diced celery One-half ounce of minced garlic One standard sachet d’epices Tabasco sauce to taste Salt and pepper to taste One tablespoon of clarified butter to garnish Two ounces of medium diced bread First, soak the beans overnight in enough cold water to cover. Second, drain and rinse the beans. Third, heat oil and add carrots, onion, and celery. Sweat onion until they are translucent, usually four to five minutes. Fourth, combine beans, stock, and ham hock with the sweated vegetables. Simmer, skimming, and stirring from time to time, for two hours or until the...

...Hazarika INDIAN INSTITUTE OF MANAGEMENT, KOZHIKODE COMPUTATIONAL COMPLEXITY Computational Complexity is a measure of the computational time taken by a particular algorithm. In a scenario where there are multiple algorithms available for a particular problem, the effectiveness of any particular algorithm is gauged on the basis of the time constraint. This is done by breaking the algorithm into its basic steps and then taking a count of each of them. Hence greater is the number of steps, greater is the complexity. Now for example, if we take two 5 bit binary numbers and XOR them, the number of steps taken is 5 and if the same process is repeated for a 100 bit binary number, the number of steps goes up to 100. The algorithm employed in either case is the same; the complexity is given by the size of the numbers. When we say size of a number n, it is defined as the number of binary bits which are required to denote ‘n’ in base 2. For example, 5 in base 10 when expressed in binary takes the form 101, thereby giving n = 3. Similarly 20 is given by 101002 which makes n = 5. Now if we XOR any two numbers each of size n=b, the number of steps taken will be ‘b’. Hence we can say that XORing those numbers has computational complexity of order ‘b’ which is denoted by O(b). This can be applied to even simpler applications like addition wherein if we are to add two n digit numbers, the minimum number of steps taken (ignoring any carry over from the previous step) will be equal to n as we approach...

...our society today our family dynamic has changed very much, and has come a long way. As of right now in 2012 we have the most diverse families such as ; two Moms, two Dads, One mother , one Father, father and mother, and interracial couples as well. In the article Gay donor, Gay Dad? It related a lot to what we were taught in class about aspects of families and the sociology of the family. Sociology of the family is the systematic study of a family, how they live? Who does the parenting? Who does household chores, occupations, and much more. In this article it talks about two same sex parents who are seeking a gay male to donate his sperm so they can raise a family. It relates a lot to what we were taught in class because we discussed in class about same sex marriages and relationships, and would it be difficult for the kid to be raised with two mommies or two daddies. In the article it also discusses who does the diaper changing and takes care of the kids most of the time. In class we spoke about parenting and sometimes there are women who are just single mothers and do all of the work, and vice versa with fathers. In our society today there are so many different aspects to what one may call a “family”, and by that I mean that one child who does have two mommies or two daddies, or just one may love it and be fine with the life we live. In our society today I think that we are slowly adapting to other ideas of a family besides the “nuclear...

...The board is a three by twelve rectangle, with numbers increasing left to right from one to thirty-six. For example, row one, column one is a one. Row one, column two is a two. Row two, column one is a four and so on. The odd numbers are red and the even numbers are black. Above the rectangle with all the numbers are two squares with a zero and a double zero. There is a formula for calculating the odds and payouts if a player places a chip on a number or across multiple numbers. To calculate these payouts, you divide thirty-six, the number of squares not including the two zeroes, by the amount of squares your chip is laying on. That number gives you the odds that the roulette ball will land in your square. Then you subtract one and you have the payout for the player. One is...

...Chapter 1 Return Calculations In this Chapter we cover asset return calculations with an emphasis on equity returns. Section 1.1 covers basic time value of money calculations. Section 1.2 covers asset return calculations, including both simple and continuously compounded returns. Section 1.3 illustrates asset return calculations using R. Updated: June 23, 2011 1.1 The Time Value of Money This section reviews basic time value of money calculations. The concepts of future value, present value and the compounding of interest are dened and discussed. 1.1.1 Future value, present value and simple interest. Consider an amount $ invested for years at a simple interest rate of per annum (where is expressed as a decimal). If compounding takes place only at the end of the year the future value after years is: = $ (1 + ) × · · · × (1 + ) = $ · (1 + ) (1.1) Over the rst year, $ grows to $ (1+ ) = $ +$ × which represents the initial principle $ plus the payment of simple interest $ × for the year. Over the second year, the new principle $ (1+ ) grows to $ (1+ )(1+ ) = $ (1 + )2 and so on. 1 2 CHAPTER 1 RETURN CALCULATIONS Example 1 Future value with simple interest. Consider putting $1000 in an interest checking account that pays a simple annual percentage rate of 3% The future value after = 1 5 and 10 years is, respectively, 1 5 10 = $1000 · (1 03)1 = $1030 = $1000 · (1 03)5 = $1159 27 = $1000 · (1 03)10 = $1343 92 Over the rst year, $30 in interest...
