Case of Doubled screen Maths Investigation
This is a portion of the main project taken from between. Case of Doubled screen(diagram only) First max. First Max. GENERALIZATION FOR N - SCREENS. First of all let us consider a simple case in which we find the fringe width on nth screen of first maxima. The diagram may be S1 S2 S3 S4 N => odd ? ................... ................... .................... .................. .................... ..................... D D D D Again if n is odd then we would obtain the fringe width d/2 & thus the separation between two maximas = d. Therefore, if n is odd then fringe width of first maxima = d /2. And if n is even, then we would get fringe width greater then that when n is odd and it would be ?D/d. Note: Here we are considering diagram type A, ie n=>odd suppose we considered B, then also we would get same result. THIS IS A VERY GENERAL CASE IN WHICH WE CAN CALCULATE " FRINGE WIDTH" FOR ANY SCREEN NUMBER .THE MAIN PART OF THIS IS THAT WE HAVE CONSIDERED THIS FOR FIRST MAXIMA. A MORE GENERAL CASE IS DISSUSED BELOW: .................................. .................................. d/2 X1 X3 X5 X7 X9 Xn-1 d/2 X2 X4 X6 X8 X10 Xn ............................... ............................... The size of First two slits is "d/2" & distance between the slits is "D'. Now a monochromatic source of light is
Printing a menu and delivering it.
Coursework: Printing a menu and delivering it. Friends of the family, Mr and Mrs Koh have decided to open up a Chinese take-away, before the opening of their take-way they need to set up a menu and have it printed. As well as setting up a menu and having it printed the couple have many other tasks, which they need to complete before the opening of their take-away and therefore will not be able to focus all of their attention on the menu. There are four possible workers (not including printing staff at Printers), as the menus will need to be printed by professional printers and we can therefore not control the time that they take, or how many staff will be used to do this. Only two workers will be needed to do each of the tasks. The Kohs want at least 200 menus to be folded and delivered and at least 800 others to have been folded before the opening of their take-away. However, they do not mind when the other 2,000 are folded I have decided to help Mr and Mrs Koh with this problem, by finding and showing them the best possible ways in which they can deal with the printing of their menu. I will do this by using Critical Path Analysis, this will show: * All of the tasks involved * The duration of the tasks * What are the longest and shortest possible times that the tasks may take * Which tasks are priority tasks * How tasks can be moved or shortened by altering the
Critical Path Analysis
Maths Coursework - Decision & Discrete Critical Path Analysis - Building An Extended Bedroom My parents have decided to build an extension over our garage to add a fourth bedroom to the house as currently my two brothers are sharing a room and it has been decided that they are getting too old to share a room and need their own privacy. They want to know the minimum time to build and decorate the new bedroom and the minimum amount of people needed to complete the job. I am going to use critical path analysis to find these requirements out. Hopefully, my work will allow my parents to find out if how long this small extension will take to build and how many workers will need to be paid in order for the task to be completed successfully. The results that I will hopefully get will tell my parents how long the project will take and how many people will be needed to get the job done in the most efficient time. First, I need to transform the problem into a mathematical model that I can solve to provide me with the information. I need to make a list of all the activities that need doing to complete the task and construct a precedence table to show the order in which the activities need to be completed. The activities to complete the job are * Collect the building materials * Prepare the garage roof for building upon * Build the bedroom walls * Fit the bedroom window * Add the
Critical Path Analysis: Redecorating a room.
nohmaanali Critical Path Analysis:Redecorating a room Redecorating rooms is a project thousands of families undertake every year and mine in particular like to redecorate every room of the house once a year. The process is carried out without any real planning or thought into the process. I feel that by carrying out a Critical Path Analysis coursework project on redecorating a typical room (for this project I will use my own room) I will be able to make the process far more efficient and save as much time and money as possible. A solution would be of great value not only in my home but such solutions would be of great benefit to many people who take the task of redecoration upon themselves. Before I can begin the investigation there are certain factors that I must assume in order to undertake the many activities involved in this investigation, the assumptions include:- * All resources are unlimited and at our disposal at any time during the project, i.e. all workers/tools/materials are present and no time is needed to collect them * Once an activity has started there will be no breaks or pauses until it is completed * The room will be received in a state where it is unfurnished and only minimal changes need to be made before work can begin such as removal of wallpaper or floorboards, items such as mirrors/hooks are not present * All resources are unlimited * All
Critical Path Analysis.
CRITICAL PATH ANALYSIS Introduction In projects made up of various activities where 'time is of the essence', the duration of each activity needs to be managed. Certain activities run simultaneously and some must precede others. If all activities are listed with their duration and preceding activities these can be networked visually. Earliest and latest times for each event (starting and finishing times for activities) can be established till the last activity. This saves time making the project as efficient as possible. Certain activities when delayed will increase the time of the entire project. These form a path known as the 'critical path' and show those 'critical activities' that have no spare time. All these steps make up the Critical Path Analysis. After analysis of the network a cascade chart can be formed with a corresponding resource histogram showing the number of workers throughout the project. The floats can be re-arranged to produce a levelled histogram where the number of workers are levelled out throughout the project. These are helpful in mall projects like cooking where they may only be two cooks to carry out the whole project ranging to large-scale projects like constructing a shopping centre. I am required to cook a meal consisting of 21 activities. This includes the preparing and clearing away of the meal. I am deciding to allocate 'get

QUANTITATIVE TECHNIQUES FOR BUSINESS DECISIONS PROJECT ON To Study an Impact on India’s Top B-Schools’ Performance by Section-wise Placement Submitted By: Batch : 2011-2013 Section-E, Group No.: 4 Group Members Sr. No. Name Roll No. 1 Mohit Arvind Singh 2011194 2 Viral Upadhyay 2011209 3 Varun Luthra 2011221 4 Vishal Jalani 2011233 Introduction Among all service sectors, the education sector, particularly the higher education system, has direct bearing on society for society’s growth and socio-economic development. Despite the strong growth in enrolments and the number of students graduating in management and business studies, business schools “are currently valued much more for their managerial expertise, cash-generation abilities and financial strength than their intellectual strength and scholarship (Thomas and Thomas, 2011). Major trends driving change in business school programs and curricula include the globalization of markets, accelerating pace of innovation, placement, advancing information and communication technologies, entrepreneurial activity, new venture creation, and rising interest in socially responsible and sustainable enterprise. However, with the increasing competition in the business school environment recently, there has been a parallel and quite critical discussion about the nature, value and relevance of business
