There are several methods one can use to implement a business system. The two methods are parallel and cut-over. The implementation stage for Riordan Manufacturing project is a display of the crucial moments that make a project an achievement or a failure. The implementation stage tells all the details of modifications made operational. The beginning started after the system had been tested and accepted by the user. This is like a packing slip for the code files in your implementation. Make note if you have added/removed/renamed/etc. any classes/methods/member variables/functions/etc. state the language (or languages) in which you will implement your project, (1) list the names of the source and header code files that will contain your implementation, (2) list the classes and functions that will appear in those files, saying whether each class or function is declared or defined in that file, and (3) list the associations (for example, inheritance, ownership, reference counting, etc.), between the classes and describes how each association will be declared. An information system is an integrated collection of software components. Components can be tested individually or in groups, or the entire system can be tested as a whole. Testing components individually ensuring that a final product is closer to completion.. Integration and system testing is a must.. Operation of

#### Setting up Microsoft Excel spreadsheet to simulate projectile motion.

Access Physics Simulating Projectile Motion Using Microsoft Excel V.J. Clarke Setting up Microsoft Excel spreadsheet to simulate projectile motion. The study of the motion of a projectile, called ballistics can be simulated mathematically by use of a spreadsheet, i.e. Microsoft Excel. To create a simulation, a few assumptions have to be made about the projectile, its launch device, and the forces acting on it in a perfect situation. The mass of the projectile is irrelevant because the acceleration due to gravity is roughly the same wherever you are on Earth, and what ever the mass of the object. I assumed that acceleration due to gravity was a constant 9.8 meters/s/s, that air resistance was negligible, and that the projectile itself was suitably streamlined to reduce drag. In fact, for calculations concerning short-range projectile motion, air resistance can be totally disregarded, but calculations concerning real life long-range artillery would need to include a compensation factor to make up for this loss of momentum. The only force acting on the projectile during its flight is the constant downward vertical force caused by gravity of 9.8 N. Formulas used. U = Muzzle Velocity (velocity that projectile leaves the gun, measured in meters per second [m/s], in this case Muzzle Velocity is always 400m/s ) a = Acceleration due to gravity, rounded to a constant 9.8

Lab Experiment 2: Database Table creation, Maintenance & Views 2.3: Preparation (1) The primary key of a table is a column (or combination of columns in a table) that are used to uniquely identify rows in a table. This means that two different rows in a table may never have the same value in their primary key, and for every row in the table the primary key must have a value. Therefore, if the primary key column(s) are declared NULL, two or more rows in the primary key can have identical values and thus they will NOT be unique. Also the definition of the primary key states that a primary key must have a value and by declaring it NULL, the user has an option of leaving it empty, which is violating the primary key's rules. The primary key column(s) must be declared NOT NULL, to maintain the integrity of data which is entered in the primary key column. A NULL values is treated by mathematically operators, such as average, like any numeric value. These functions operate on the NULL without any problem, but produce an answer which has a value NULL. (4) The following are the entities that will be tested for normalisation, using the 1NF, 2NF and 3NF: SUPPLIER (CODE, NAME, CONTACT, ADDRESS 1, ADDRESS 2, POST CODE, TOWN, PHONE, FAX). INVENTORY (ITEM_CODE, STORE_LOCATION, QUANTITY). st Normalisation Form (1NF) basically states that the entity is in the 1NF if it consists of

#### 3SFE518 Computer System Organisation - Piping

Coursework for: Computer System Organisation 3SFE518 Malshani Nanayakkara 2007020 CONTENTS Introduction - About the Piping 3 Program Listing 4 Screenshots 7 ABOUT THE PIPING In order to be able to communicate between two terminals, pipes have been used. As pipes are FIFO structure (First In First Out), it is well suited to be used for such an application. Two pipes are created, one used to define a communication channel from the server terminal to the client and the other to define a communication channel from the client terminal to the server terminal. Lets call these two pipes, np1 and np2, where np1 is the connection from the client to the server. In the program running on the server terminal, the pipe np1 is opened in the read only mode. Thereby, allowing it to read the information being sent by the client terminal. In the program running on the client terminal, the pipe np2 is opened in the read only mode so the information being written by the server can be read by the client. Whenever the information from the pipe is being read, it is temporarily stored in a buffer before being printed out on the screen. PROGRAM LISTING fullduplex.h //Reference: http://developers.sun.com/solaris/articles/named_pipes.html #define NP1 "/tmp/np1" #define NP2 "/tmp/np2" #define MAX_BUF_SIZE 255 server.c //Reference :

#### Operations in a shuttle loom

Operations in a shuttle loom The first operation in a shuttle loom is called shedding. This is where a gap is created in the warp so that the weft can go straight in through the gap. A hield frame is used to shed the warp, which only contains one yarn. So what happens is all the odd number warps would rise above the even number warps so that weft insertion could take place. The gap between the odd and even warps is known as the shed. There are three frames for odd warps and three frames for even warps. The second operation is known as picking which is basically weft insertion. This is where the weft goes through the shed. A shuttle is used for picking which keeps going from one side to the other side of the fabric through the shed. The edge of the fabric is known as the selvedge, which is very strong, which is important so the fabric does not become frayed. There is a bristle inside of the shuttle, which stops the yarn becoming loose. This is important as if the yarn becomes loose it can lead to knots which would slow down the process. The area between the yarn and the fabric is known as cloth fell which is the point of fabric formation. Beat up is the process where the weft gets pushed into the cloth fell. To do this a reed is needed. There are three to four ends in each dent, which are the gaps in each reed. Then what basically happens is that the ends get beat up into
