Digitala tjänstens registreringsprocess ? hur påverkar den helhetsintrycket?
The outset of this thesis is to raise questions on how we design for the mobile context and the capabilities of smartphones. Not only the presentation but also the use of input and interaction between a service and a user.This work evolves around sign up forms and answers the question: How does the sign up process affect the holistic perspective of a digital service regarding usability and user experience?
This thesis consists of a case studies, and design experiments conducted on Twitter, Instagram and Randos sign up processes to explore if and how the usability, and the user experience could be affected and im- proved.This concluded some important aspects to be considered when designing sign up forms for a digital service.The usability, and the user experience is not only affected by user interaction, and the choice of input method but it?s also affected by which data the service is requesting, and more important; if that data is motivated to request by the service..

Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Debatten om Biblioteksdatoriseringen : tendenser i Biblioteksbladet, Bis och DIK-forum 1970-1999
The purpose of this thesis was to trace and discuss tendencies in the debate of the computerization of the libraries, in Swedish library press during the period of 1970-1999. The set-out was the issue of how the library journals, as representatives and mouthpieces of a by tradition humanistic profession, coped with a revolutionary innovation related to a field (data technology) which they hadn't any knowledge or even interest in. The examination included three Swedish library journals: Biblioteksbladet with connection to Sweden?s most established library organization (SAB); Bis which is founded upon a socialistic base and; DIK-forum rooted in the union. The analysis of the debate was partly based on three different sets of values related to data and systems development.
Företagsförvärv : En studie av onoterade små och medelstora företag
Sweden is facing a shift in generation where the people born in the 1940s are starting to retire which results in consequences. Before the year of 2013 more than 180 000 companies will have to change owner. A study indicates that the majority of all Swedes in the age of 18-70 can consider becoming company owners.Only ten percent of the companies for sale will reach the company broker and another 15 percent will be mediated by legal experts and accountants. This means that 75 percent of the companies for sale will not be available for the public market. As a potential buyer this is a problem.
Social fildelning på arbetsplatsen : Traditionell och social fildelning
This paper describes how files and information can be shared in organisations and workplaces. We studied and compared the traditional file sharing in Microsoft Active Directory and the Social file sharing that comes with Microsoft SharePoint Sites. We used qualitative studies based on interviews with system administrators, management and by our own observations to acquire the necessary data. Using independent research, we were able to analyze the data and show the general difference between the traditional and the social file sharing systems. Social file sharing enables the user to easily store and share files in a flexible online environment.
Utvinningsmetoder och användningsområden av data ur datalager inom industribranschen
I datalager samlas information från flera olika system och sparas på ett gemensamt sätt. Informationen i ett datalager ger en holistiskbild över organisation och bör användas som beslutsstöd. För att utvinna information ur datalager finns flera olika metoder och informationen kan sedan användas inom flera olika områden.Syftet med studien är att undersöka vilka metoder som används för att utvinna informationen ur datalager inom industribranschen samt inom vilka användningsområden informationen används.För att besvara frågeställningen genomfördes fem intervjuer med företag i industribranschen. Resultatet visar på att vissa metoder för att utvinna information ur datalager används framför andra och inom datautvinning används inte den förutsägandekategorin alls. Framförallt använde sig företagen av informationen på kundsidan och såg det som ett levande projekt som skall täcka in hela processen i framtiden..
Företagens aktuariella antaganden - vilka faktorer påverkar dem?
The purpose of our essay is to study the institutional-, demographic and accounting theoretical factors that influence an organisations actuarial commitment.The research was performed through a web based survey, with complimentary telephone interviews, directed to companies listed on Stockholm Stock Exchange A- and O-list on the 30 of November, 2003.Our data was analysed with a Median test, Kolomogorov-Smirnov test, T-test and a Mann-Whitney test. The purpose of the Mann-Whitney test was the low number of respondents that took part in the research. The Kolomogorov-Smirnov test was done to determine whether the population variances was equal or not. The data showed that organisations with a majority of female employees assume a lower salary increase, and a higher average age than other companies with a male majority. Only 2 of 11 hypothesis can be accepted as temporary truths but several other visible relations are indicated in our research, but can not be statistically proved.We think that the major problem with our is the time it was performed.

Voxelbaserad rendering med "Marching Cubes"-algoritmen
Det finns flera olika metoder och tekniker för tredimensionell rendering, alla
med olika för- och nackdelar som lämpar sig för olika applikationer.
Voxelbaserad rendering har använts flitigt inom vetenskapliga områden, främst
inom det medicinska för visualisering av volymetrisk data. Tekniken används nu
inom flera olika områden för tredimensionell rendering, t.ex. i datorspel, i
matematiska applikationer och vid geologisk rekonstruktion.
I den här rapporten kommer voxelbaserad rendering med Marching Cubes-algoritmen
undersökas för att se hur den lämpar sig för realtidsapplikationer. Området
behandlas dels teoretiskt, men även praktiskt då en implementering av Marching
Cubes gjordes för att genomföra några tester för att se hur prestandan
påverkades.
Av testerna framkom det tydligt att algoritmen lämpar sig väl för
realtidsapplikationer och dagens grafikkort.
Strategic Evaluation -A study of its purpose in SIDA and SADEV
Background and Problem discussion: Strategic evaluations are important as they providecrucial information regarding Swedish development assistance and recommendations on howto face problems and inadequacies found in the evaluations. Therefore, the follow up ofrecommendations is of great significance as well. Unfortunately, SIDA?s ManagementResponse system for follow-up of strategic evaluations has not been functioning in asatisfying way and needed actions have not been taken. Thus, Swedish developmentassistance has been criticised for the lack of implemented actions and the public has startedto question the work carried through by the organisations.
En obekväm statistik ? en jämförande studie av CO2-utsläpp från transportsektorn
Syfte: Syftet är att undersöka huruvida Sveriges officiella CO2-data från trans-portsektorn är internationellt rimliga åren 1990-2004. Sverige har uppvi-sat en internationellt lyckad reduktion av CO2-utsläpp samtidigt som Väg- och transportforskningsinstitutet visar att Sveriges CO2-utsläpp från vägtrafiken kan vara dubbelt så höga som rapporterat. Metod: Undersökningen sker genom en jämförelse mellan Sverige, Danmark, Norge, Spanien och USA. Ekonomisk tillväxt sätts i relation till CO2-utsläpp och transportsektorns utveckling och ländernas personbilsparker undersöks. Tyder ingenting på missvisande data torde Sveriges lyckade CO2-minskning vara ett resultat av effektiv miljöpolitik.

Swedish SME Financing - Evidence from the Game Industry
The objective of this thesis is to examine the capital structure of Swedish small and medium sized enterprises (SMEs). Accounting data from Swedish game developers, combined with the result from a survey, is used to examine their financial conditions and capital structure decisions. We find that non-debt tax shield, firm size, growth opportunities and age are, to various extents, the determinants of capital structure in the game industry, while effective tax rate and asset structure have marginal effects. Our study also implicates that most of the existing capital structure theories can explain SMEs leverage decisions to some extent; however, some adaptation is needed to fit these theories into the SME context. Additionally, we find the existence of a financial gap in the game industry which might need efforts from both demand side and supply side to eliminate..
