Today we live in a world where the demands increase in the aeronautics industry. This creates a situation where no mistakes are allowed about the regulations and for those who are supposed to follow these. Safety comes first, tracking of components, Service Bulletins which are recommendations from the manufactures and Airworthiness Directives which are demands from the authorities, these need to be updated at all time and everything that is done on a aircraft need to be documented.This creates a situation where today maintenance shops need to have full control of all parts of the organization, which creates a need for a working data system.The goal with this exam work is to evaluate the best way to implicate the new bought data system called "System Aircraft Management" on the basis of the needs of Täby Air Maintenance AB. The system are supposed to get started technically and also be implicated to the users of the system. This work will be focused to create a effective working plan to get SAM implicated with no interruption in the daily work.

One problem in today?s indoor air quality lies within insufficient ventilation. Dynamic ventilation can be obtained by implementing a Demand-Controlled ventilation (DCV) system. DCV systems adjust the ventilation in a building by calculating the impact made by its? occupants.

The purpose with this study was to elucidate the pros and the cons with a sale support system. This has been narrowed down into two questions: ?What are the pros and cons for a company that have a sale support system? and what are the pros and cons for a company that does not yet have a system?? Configurator that is a sale support system has been studied. It is a system that presents products by accepting different functions, qualities or parts that are possible to match. It can be used in business-to-business or business-to-consumer situations, through different sale channels, namely direct sale, indirect sale and online sale.

Classification systems express an idea of the world as it was when the systems was made. If the classification system is not revised there is a possibility that the system will become antique and hard to apply to different subjects. The purpose of this study is to see if the SAB-system is a classification system which shows a reflection of the subject Religion that is equivalent with that of Swedish universities. The ideas which are behind the classification of the subject religion in the SAB-system have been analysed, as well as the structuring of the scientific discipline Religion at the universities. The result will show if the SAB-system can classify the subject religion in a satisfying way at university libraries.

This report has explored how to design and develop an ordering system for television and DOOH commercials. Usability theories have been considered and also guidlines for system devoloping, this includes the making of a PACT analysis and a demand specifcation. To ensure that the users of the systems are in focus a pre studie has been performed on location of the company which is the intended user of the system. Finally an interactive prototype of an orderingsystem has been created to illustrate the functions and tools which the fnal product should have..

If P&C Insurance Company faces a challenge when their treasury system needs a new interface to a software as a service application. They need a suggestion for configuration for how the system and the application can work together. The work presented in this report is a suggestion for how you can make business configuration of an IT-based Treasury System in general. The exact configuration for the case received from If is presented as a separate report, found in Appendix A and is called the If-report. The If-report presents the suggested technical set-up of the configuration.

This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g.

Vad många inte tänker på då de har ett relativt avancerat olinjärt system som de linjäriserat till ett tidskontinuerligt styckvis affint system är att det inte är helt självklart och enkelt att hantera detta system. Eftersom vi i de flesta fall vill kunna hantera ett angivet system med datorkraft, och därmed måste sampla systemet, behöver vi kunna beskriva ett samplat tidskontinuerligt styckvis affint system med ett tidsdiskret system. Vid första anblicken av detta problem kan det verka ganska enkelt. Vad många gör är helt enkelt att skapa en tidsdiskret beskrivning för varje mod i det styckvis affina systemet var för sig och behålla de gamla modgränserna. Detta visar sig dock kunna ge ett felaktigt uppförande hos systemet.

A new system of public transportation that can simplify and shorten the trips made throughout the city, anddo that both cheap and environment-friendly. Sounds like good news. This new system, though, require anall new type of infrastructure, differing from what we are used to see in our cities. Podcar, or PRT, as thesystem is called can become a transport revolution, possibly. If that revolution does happen it is crucial that webeforehand have studied the possible effects it can cause on our city environment, from a spatial point of view.This thesis thoroughly describes the function and essence of the PRT system and presents what is availabletoday and in what forms.

Integration av system har varit ett aktuellt område under de senaste åren. Det har då främst handlat om integration av system internt på företag. En av anledningarna till det stora intresset av web services är möjligheterna att integrera olika system, exempelvis stordatorbaserade och Windowesbaserade system med varandra. Web services handlar om att kunna integrera system, både internt på ett företag och externa mellan olika företags olika typer av system. Allt detta görs via Internet och bygger på att man utgår i från standards när man bygger web services.

Uppsatsen undersöker den svenska marknaden för CRM-system utifrån faktorer som företagskategori, kundrelation, befintligt kundrelationsstöd m.m. Vilka funktioner i ett system som företagen uppskattar mest undersöks också samt hur faktorer typiska för mjukvara påverkar situationen.Resultaten visar att det finns ett behov bland små och medelstora företag för CRM, dock inte för alla företag. Många företag använder egenutvecklade system, kanske för att de kommersiella systemen inte motsvarat deras behov. Funktionsmässigt uppskattades grundläggande funktioner mest, och fördelningen mellan CRM-områdena var jämn. Gällande mjukvarukaraktäristik ser företagen funktionaliteten som den primära faktorn i deras val av CRM-system.Det är en klar fördel att kunna erbjuda ett system på det nationella språket..

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.

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..
