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 :

Human Computer Interaction Project.

Human Computer Interaction Project Evaluation of Olympus C1400l Digital Camera Group Members: Lorna Brodbin 9838635 Jean Cronin 9838856 Gillian O'Sullivan 9840435 . Introduction "Every picture tells a story" An old saying that holds true. A picture can tell us more in an instant than a thousand words ever could. A picture records emotions, expressions, feelings and conveys them easily to the onlooker. Photographs capture hundreds of years of history be it on a world scale or at a personal level. We capture our weddings, births, birthdays and other occasions dear to us on camera because we want to hold on to that moment forever. Every time we look at a photograph we remember that day and relive that moment. The camera never lies. It takes a moment in time and freezes it. We rely on photographs as a tool to help us to understand and to remember the history of the world. Most of the worlds great historical events have been captured on film. A photograph of an innocent victim of war makes the victim real, like someone we knew rather than a name in a paper, and touches us far more deeply than stories in a book. Peoples descriptions of events are often tainted by exaggeration, imperfect memories and personal opinions but there is no denying the evidence of a photograph. The camera has come along way since the days of Niepcei. The first cameras were big and

3SFE504 - Object Oriented Programming - Linear and Independent Hash Table code

School of Informatics DEPARTMENT OF INFORMATION SYSTEMS AND COMPUTING 3SFE504: Object oriented programming COURSEWORK Student Id Student First Name Student Surname 2007053 Kavindya Isuru 2007020 Malshani Nanayakkara CONTENTS Page Introduction 3 Implementation Group Work 5 Student A Implementation 10 Assumption 24 Student B Implementation 25 Testing Student A: Test Plan 44 ScreenShots 45 Student B: Test Plan 50 ScreenShots 51 Self-Evaluation Individual Reports 59 INTRODUCTION This coursework was done in teams' of two group members. Group V was made of up of: N.T. I Kavindya and Malshani Nanayakkara In this project, we were asked to create a dictionary object, which was capable of storing words and its definitions. Each word could contain more than one definition. The dictionary object we created should contain the facilities of viewing the words in the dictionary, adding new words, searching new words and printing it to a file. The words and their definitions would be stored in an external file called 'defs.dat'. So every time, our application is run, the words and their definitions should be read in. We each created a hash table to accommodate these. Student A's part, done by Kavindya, reads in the word and stores them using the linear rehashing technique. Student B's part, done by Malshani, stores the words in the hash table using

This report is to describe the process I went through to create a 3D model of a chosen object and to animate it using 3D Studio Max software.

Contents 2. Introduction and Original Ideas. 4. Chosen idea. 5. First steps of creation. 7. Adding more objects 9. More detail through materials. 1. Lights, camera, animation. 2. Problems during creation. 3. Answers to questions. 5. References. Introduction This report is to describe the process I went through to create a 3D model of a chosen object and to animate it using 3D Studio Max software. During this report I will cover the following aspects: * The first ideas of which I came up with, and how I originally intended to create them using 3D Studio Max. * My chosen idea and how I began to set out my plan to create the object. * The steps I progressed through during creation. This will be the most detailed and significant part of the report. * Problems I had during creation and how those problems were tackled, also a few things I believe could be done better in the future. * Answers to questions provided by tutor as part of my assessment. Original Ideas To start with three ideas were very basically sketched and ideas of how they would be created were thought of. The three electrical objects which were short-listed were: Mobile phone: To create this it would take a simple couple of boxes representing different components of the phone (main unit, battery, sim card), the animation would show all these come together. Laptop computer: The Laptop would be

Test Thrice, Launch Once: Arian 5 disaster.

Test Thrice, Launch Once: Arian 5 disaster The Failure On June 4, 1996 an unmanned satellite-deploying rocket Ariane 5 was launched in Kourou at 1233 GMT. After about 40 seconds into the flight, the self-destruct of the space rocket was triggered. This was done in accordance with safety regulations due to the rupture of the links between the boosters and the main core stage of the rocket, caused by a dramatic change in direction that had taken place roughly 3 seconds earlier. The rocket was carrying four satellites that were going to be sent into orbit to monitor the sun. Ariane 5 was the result of a £5 billion launcher development by the ESA (European Space Agency), and the explosion itself destroyed the rocket and its payload, at a total cost of £500 million. The Cause of the Failure The origin of the failure was narrowed down to the Flight Control System, and more particularly, to the Inertial Reference System (SRI). To investigate the cause of the failure the European Space Agency (ESA) appointed an independent board. The following chain of events was established: * First 36 seconds of the flight were normal. * At H0+36.7 active SRI declared an operand error. The reason was a software exception, caused by the data conversion from a 64-bit floating-point number to 16-bit signed integer. That conversion can only be applied to a number less than 216, but was

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
