Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator
In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..
Finns det risk för att Sverige gÄr in i en ny fastighets- och bankkris?
The purpose of this thesis is to investigate if there is a risk that Sweden will go in to crises at the house market and in the bank sector. The Swedish house prices have in the last years growth very high and quickly and are now over the development in the beginning of 1990. The method I use to investigate this is a multiple regression model. I follow a regression that both OECD and the Swedish Riksbank use. The difference between my analyse and theirs is that we use different periods..
HÀlsoresan : Patienter och patientperspektiv pÄ hÀlsohemmet FöllingegÄrden 1976?1990
In the 1970s and 1980s, Sweden held about 15-20 certified health resorts that wanted to improve peoples? health with vegetarian food and alternative medicine.

En generell processkartlÀggning av leveransplanering för biobrÀnsle i Sverige
The contribution of biofuels to the total consumption of energy in Sweden must increase to 49 % in order to meet the goals for the year 2020 set by the European Union. In order to do so, improved information systems are needed to support the business processes within delivery scheduling between customers and suppliers.Enterprise Architecture (EA) is a concept to enable the alignment of Business processes and Information Systems. EA is the framework for the architectures of business, information and applications. With a comprehensive view of the architectures, an Information System aligned with the Business processes can be enabled. The first step in the development of an Information System is documenting the business processes.The goal of this study is to clarify a generic sequence of activities performed within the delivery scheduling process and the information needed to perform the activities.Data for the study was collected through qualitative interviews, first through a meeting with the respondent and after that a following telephone interview with in total 5 suppliers and 6 customers of biofuels.
Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige abÂ
ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.
BAKTERIER SYNS INTE Sjuksk?terskors upplevelse av att v?rda patienter b?rande av multiresistenta bakterier. En kvalitativ intervjustudie
Bakgrund: Multiresistenta bakterier (MRB) ?r bakterier som har skapat resistens mot
antibiotika. Antibiotikaresistens har blivit ett globalt problem som leder till att vissa infektioner
blir allt sv?rare att behandla. Problemet har ocks? blivit alltmer omtalat, och det arbetas aktivt
f?r att f?rhindra fortskridande utveckling.
Universell stolkonstruktion: Till HĂ€gglunds fordon
NÀr man pÄ BAE Systems HÀgglunds AB konstruerar en ny stol till ett fordon sÄ har man tidigare individanpassat stolarna utefter dess position. MÄlet med detta examensarbete var, istÀllet för att individanpassa en stol, konstruera en stol som gÄr att anvÀnda pÄ flera positioner i flera fordon. Ursprungstanken var att konstruera en stol som skulle fungera att anvÀndas i tre stycken HÀgglundsfordon, Armadillo, Bvs10 och Cv90, dÀr stolen skulle fungera pÄ förarplats i Cv90 och Bvs10 samt som chef- och skyttestol i Armadillo och Cv90. Eftersom HÀgglunds tillverkar fordon med inriktning mot försvarsindustrin medför det att stolarna sitter i fordon som idag anvÀnds i krigsdrabbade omrÄden vÀrlden över. Detta bidrar i sin tur att kraven pÄ stolarna blir mycket höga.

Att utveckla medicintekniska informationssystem pÄ rÀtt sÀtt : En studie om regulatoriska aspekters pÄverkan pÄ systemutveckling och IT-innovation inom hÀlso- och sjukvÄrd
IT is often seen as a solution to many problems concerning effectiveness in organizations. Information systems within the healthcare sector is often viewed as medical devices rather than just systems or services. These medical devices are thoroughly regulated by laws, standards and certifications. In this study I participated in an innovative project that aimed to bring new life and use to the old fashioned patient journal by giving it a visual representation through the use of an avatar. I aimed to study the effects of regulators connected with the patient journal as a source of information for the innovative project.

AnvÀndarvÀnlighet i blötutfodring : enkÀtstudie för smÄgrisproducenter
It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.
