This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database. Although Ruby on Rails was completely new to me, I decided to use this framework instead of PHP, which I already have a good knowledge of, because of the benefits Ruby on Rails provide.

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

This thesis presents the design and implementation of an accounting and status notification system for the LPRng print spooler. A solution using SNMP to query for needed accounting and status data is presented, a design built upon this, and an implementation produced. As the system derives from the requirements specification, it will make no attempt to solve all printer accounting problems or to offer compatibility with all printers, database management systems or print spoolers. However, several solutions for printer accounting are discussed and the best solution derived from the requirements specification will be chosen..

Vid utveckling av elektroniska läromedel är användbarhet en viktig faktor. Vad som är användbart är beroende av användarens behov och förutsättningar och läromedel har ofta en heterogen målgrupp. Målet med den här undersökningen har varit att besvara frågan hur e-läromedel kan användbarhetsanpassas för olika lärstilar. Undersökningen har genomförts med hjälp av litteraturstudier samt intervjuer med läromedelsförlag. Delar av Dunn & Dunns lärstilsmodell, specifikt sinnespreferens och informations­bearbetning, har relaterats till aktuella riktlinjer för användbarhet i e-läromedel.

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.

Most often when developing a new system there is a need get a functioning testtool up and running. Including time, cost and resources the solution isn?t always obvious, developing your own or buy one ?of the shelf?. The purpose of this thesis is to study how a general testtool for executing functional tests should be designed to be reusable, be based on recognized knowledge and be able to fast and simple be customized for different types of systems. Key functions from the litterature is presented and used in the design of a testtool prototype.

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

This Masters thesis in Library and Information Science has the title The New Information Desks at Malmö Public Library . During the rebuilding of the library in Malmö a new information desk was developed. This desk differs to a great extent from conventional information desks used in libraries. The information desk is triangular with rounded edges which allows the librarian and the user of the library to work side by side without any physical barriers. The aim of this thesis is to explore the requirements for the information desks formulated by the library and how they are perceived by the librarians and the users of the library.

This field study examined how elderly and cognitively disabled people used and experienced a social companion robot. The following pages explores the questions: Which are the physical, social and affective qualities during the interaction? The aim was to through observations see how qualities of interaction could activate different forms of behavior. The results show that motion, sound and the eyes together created communicative and emotional changes for users who felt joy and were willing to share the activity with others. The robot stimulated to some extent users to create their own imaginative experiences but often failed to involve user or group for a long time and was also considered too large and heavy to handle..

Immersion is a construct that measures how deeply engrossed a user is with any mediated situation. In the field of game design, immersion is a significant aspect of what makes a game enticing, and as such it is of pivotal importance to create and maintain it to keep the player's mind off the real world while inside the confines of a game framework. According to the GameFlow theory, it is one of seven key tenets of evaluating and implementing a successful game design. Yet, certain multiplayer online games are designed in a fashion that in some cases seem to break immersion, where the player is frequently put out of action, sometimes for minutes on end. In this study, using online questionnaires, we discover that players, despite claims otherwise, seem to be in several ways affected negatively by this breaking of immersion.

Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

When different type of programs are developed one wants to make these adjustable to future changes and requirements. It must be done a good design of the program from the beginning to make it possible to continue development of it without having to redo big parts of it to high costs. In the area of object orientation there are design pattern, which can be used to design systems that can be adjusted to new changes in an easier way. I have in this thesis chosen to take a closer look at how to design a program that sends SMS to cell phones through a system of an operator. One requirement on the program is that it has to be possible to change what operator to send though in an easy way.

This project aims at investigating if the use of UML as a support to small-scale development ofan embedded system is relevant. The investigation is conducted by using UML during the initialphase of the development ofTelfafill, a filling machine by the company ?Telfafill AB?. The aimof the development of Telfafill is to separate the user interface from the control unit. In additionto this main objective, Telfafill AB would like possible changes to, and additions of,functionality of the filling machine to be investigated.Within the boundaries of this project, the development of Telfafill reached a full requirementspecification of the proposed system, and contact was made with potential external developers.No prototype construction had been started when the project ended.

User comments:Availability and Utilization in Online News Affiliated with Local Daily PressAuthor: Susanne AlmgrenSupervisor: Mats EkströmConstituent: Dagspresskollegiet (Annika Bergström/Ingela Wadbring)Course: Term Paper in Media and Communication StudiesTerm: Spring Term 2012Pages/word count: 91 pages / 38 334 wordsObjective: To examine the users availability to the user comment feature and how theusers utilizes the user comment feature in the context of an online news site affiliatedwith local daily press.Method: Mixed methods approach, content analysis and discourse analysisMain result: In this context, three out of four news stories (76.5 percent) has beenallocated with the user comments feature. The highest availability to the user comment feature was found in news themes covering sports and entertainment, followed by financial news. News stories lacking the user comment feature weremainly found in news themes concerning crimes and accidents. The user comment frequencies are not normally distributed along news stories. On the contrary, 62 percent of the news stories did not get any user comments at all.
