A business is always dependent on its customers. It is therefore important to ensurethat customers are satisfied with the product and the warranty included.The study was conducted in cooperation with the building contacting companySkanska Sweden. The aim is to use interviews to collect and process experiences in order to answer the question: How should the recovery process in the construction industry be performed to ensure a professional handling of warranty? The results have shaped my conclusions and I have turned them into a proposal that companies in the industry can benefit from. The study indicates that the industry is not geared for a five year warranty, which was introduced in 2004 and 2006.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

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.

Bakgrund: ERAS (Enhanced Recovery After Surgery) är ett standardiserat multimodalt vårdprogram vid elektiv kolorektalkirurgi, som syftar till snabbare återhämtning och kortare vårdtider genom ett tvärprofessionellt samarbete.  En vecka innan planerad operation träffar sjuksköterskan patienten för ett samtal om vårdförloppet. Syfte: Att identifiera och beskriva patientens upplevelse av sjuksköterskans ERAS- samtal och dess betydelse för patientens delaktighet i sin vård.   Metod: Datainsamlingen skedde genom kvalitativa intervjuer. Tolv patienter, nio män och tre kvinnor har intervjuats. De ljudinspelade samtalen har transkriberats ordagrant och analyserats med hjälp av tolkande fenomenologisk analys (Interpretative Phenomenological Analysis). Resultat: Analysarbetet resulterade i fem olika teman; bli sedd, trygghet, tillit, ansvar samt delaktighet. Alla teman relaterar till varandra och illustrerar en positiv och en negativ sida av den upplevda erfarenheten. Tillsammans bildar en helhet av upplevelsen; ERAS- samtalet och dess betydelse för patientens delaktighet. Konklusion: Resultatet visar att patienterna känner sig sedda under informationssamtalet.

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..

Emerson Network Power Energy Systems är ett globalt företag som skapar system för avbrottsfri strömförsörjning för tele- och IT-kommunikation. Till följd av uppköp av företag har Emerson utveckling i flera länder. De olika länderna använder dessutom olika CADsystem. Detta är ett hinder för samarbetet mellan utvecklingsavdelningarna. Den svenska avdelningen av företaget har lagt mycket tid på att utveckla ett PDM-system och anpassa det till det CAD-system som används i Sverige (NX).

Linjäriseringar av olinjära system är mycket relevanta eftersom det finns en i förhållandevis enkel och omfattande matematisk teori kring linjära system, till skillnad från allmänna olinjära system.För vissa olinjära system är det svårt eller inte ens möjligt att genomföra en analytisk linjärisering.Orsakerna till detta kan vara hög komplexitet av systemet eller avsaknaden av ett analytiskt uttryck.Numerisk analys kan vara en lösning på detta problem.I detta examensarbete används framåtdifferens och centraldifferens för att genomföra de derivata-approximationersom behövs för att genomföra en numerisk linjärisering av ett olinjärt system.Rapporten behandlar även vad som sker då det är dålig upplösning på den indata som används när man genomför enlinjärisering, vad som händer med heltal och binära signaler om de ingår i ett system som linjäriseras ocheffekten av att ha olika samplingstider för olika delmoduler i ett system som linjäriseras.Slutligen undersöks numerisk bilinjärisering av ett system på bilinjär form och en jämförelse mellan analytisk linjärisering och bilinjärisering görs..
