Information om kundval, en förutsättning för valfriheten? : en studie av hur tre kommuner arbetar med informationsspridning om kundval inom hemtjänsten
This paper studies, from a client perspective, how three Swedish municipalities work with information about a voucher system in homecare. The paper is a qualitative study using structured informant interviews and analysis of documents. The interviewees are responsible of information about the voucher system in the municipalities. The studied documents describe and clarify the voucher system of the municipality. Neo-institutional organization theory is used to analyse the result.
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..

Studie av beslutsprocessen vid anskaffning av ett IT-system
Arbetet ett företag lägger ner för att komma fram till ett beslut om en större investering i till exempel nya maskiner är oftast omfattande och ett resultat av ett strukturerat arbete med klara strategier för att i största möjliga mån uppfylla behovet som orsakade anskaffningen. Däremot har en investering i informationsteknologi av olika anledningar inte setts som vanliga investeringar utan ofta genomförts utan en ordentlig utvärdering. Med denna uppsats ville vi försöka ta reda på om det verkligen förhåller sig så att företag anskaffar IT-system utan att göra någon ordentlig analys av de problem eller behov som förorsakat anskaffningen eller om de följde de metoder och modeller som finns tillgängliga för att komma fram till ett beslut om anskaffning av ett IT-system. Vi utförde vår undersökning vid tre produktionsföretag som hade anskaffat liknande system. Vid vår analys valde vi att applicera förändringsanalysmetoden, FA/SIM och Simons vedertagna beslutsprocessmodell på det empiriska materialet.
Svensk strategisk kultur idag : neutralitet eller solidaritet?
This essay attempts to examine the discourse of the Sweden democrats in relation to thevalue system of the Swedish national school.To analyse the political texts I use discourse analysis and especially the method and approachconducted by Judith Lee Bacchi. Bacchi focuses on the construction of a problem in variouspolitical discourses. When performing this kind of analysis the main question is (accordingto Bacchi): ?What is the problem represented to be??I find that the Sweden democrats construct the ?migration politics? and the ?multiculturalpolitics? that is guiding the society as the cause of most problems in our society. To solvethe ?problems? they promote a nationalistic and a cultural racist discourse especiallypinpointing the ?Muslims? as being a problem.Since the Sweden democrats are striving to implement their discourse in the society andschool, and since their discourse already are reproduced by solar students in the classroom,I find it important to examine the essence of their particular discourse and contrast it withthe current value system of the Swedish schools.I don´t find the nationalistic and racist discourse of the Sweden democrats to correspond tothe value system of the Swedish school, mainly due to their strive to create alienation, andby labeling individuals in a reductive manner, instead of using apparent differences as asource for democratic discussions in the classroom.
Omläggning av skiftgång
The digital printing market is changing faster now than before and the ability to adjust to newsituations has become more importat to a printing company. An efficient internal communicationis essential. At Elanders Digitaltryck a decision was made in august 2002 to look over the shiftworking system for the printer operators. In this paper, an investigation of the possibilities tochange the existing system to a better one was made.The project resultet in four different timetabels. The construction was based on theoretical studiesand an analysis of the current situation at the workplace.
Skönlitteratur på svenska folkbibliotek: En diskursanalys
The view on which kind of fiction that should be mediated to the public through the Swedish public library system has since the late 60´s been dominated by what in this Master?s thesis is called: ´the discourse on quality of literary fiction´. The aim of this thesis is to examine to which extent this discourse still plays an active role in the Swedish public library system or if that discourse has been replaced by a more market-led, demand responsive view, where the features of ´quality´ and ´culture´ have been downplayed and replaced by a ´customer?s service view´ on how and why fiction should be mediated to the public. The methodological and theoretical perspective in this thesis is led by the understanding of the discourse analysis in Michel Foucault?s ´The Archaeology of Knowledge´.
Kontrolltorn : En informationslösning för tredjepartslogistik
The demand for shorter lead-times and increased delivery reliability puts pressure on companies to provide more efficient logistic services. One strategy to deal with this demand is by outsourcing logistics to a third part. The development of logistics information systems enables increased control over business supply chains. This is why Green Cargo aims to create a Logistics Control Tower (LCT) solution to provide it?s customers with better information with higher availability.
Levbart transportsystem i Uppsala
In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.
CAP KC3-12 : Design and finite element analysis
In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.
Ledarskap inom ramen för ett systemutvecklingsprojekt : fokus på en arbetsprocess med stöd i Vattenfallsmodellen
Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.
Analys av nivåproblematik i dränagetank på Ringhals 1
The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.
Business intelligence : Framgångsfaktorer vid användningen av ett BI system
The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.
PPM - Passivt Placerande för Många : En analytisk studie av premiepensionsspararnas avsaknad av strategier för fondval
Introduction: In 1998, the pension system was changed and the so called PPM system was introduced. The PPM system is partly fund-based, partly distribution-based. There are approximately 700 different investment funds to choose between, at a maximum five for each individual. For persons who are not familiar with the financial market, the choice might be difficult. The lions? part of the investors do not seem to have an active strategy.
Teststrategier och användning av testautomation : En studie utförd på företaget Extenda AB
In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.
