Med anledning av den snabbt växande populariteten för mobila enheter såsom iPad/iPhone, Android och Windows Phone 7 öppnas nya möjligheter för affärsverksamheten. Ett exempel är mobil åtkomst till Microsoft SharePoint, en webbplattform som erbjuder en bred uppsättning verktyg för bland annat dokumenthantering och projektsamarbete. Den här studien har utvärderat ett antal lösningar för att tillgängliggöra SharePoint på mobila enheter. Utvärderingen har fokuserat på de två huvudaspekterna användarvänlighet och säkerhet, eftersom studien utfördes på ett företag med omfattande hantering av sekretessbelagda filer. Lösningarna i studien har delvis testats via mobila enheter och delvis endast undersökts genom dokumentation på grund av brist på möjlighet till driftsättning av de mer avancerade lösningarna.

The purpose of our study is to find out if insiders in Sweden generate abnormal earnings through insider trades. We want to pinpoint the cause for abnormal earnings by dividing transactions after company market value, size of the trade and type of insider. A quantitative approach using the market model have been used. We have conducted an event study over two short term event windows. We conclude that insiders in Sweden generate positive abnormal earnings for sales and negative for purchases in our ?long? event window.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

Purpose: The purpose of this study is to examine the difference in return between Swedish and Russian hedge funds while considering the risk taken.Method: This study is based on quantitative data on funds' historical returns from the electronic database Morningstar.se. Additional data is taken from the funds websites, the Swedish National Bank and Fondbolagens förening.Result and conclusion: All hedge funds, both the Russian and Swedish performed better thanthe index. The Russian hedge funds nevertheless performed better than their Swedishcounterparts in all three evaluation methods..

In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..

Tidigare studier har visat en korrelation mellan muskelgrupper, särskilt gällande styrka mellan olika muskelgrupper i samma extremitet. Syftet med den här studien var att se om maximal isokinetisk muskelstyrka i låret korrelerar med maximal isometrisk handgreppstyrka hos friska individer >60 år. Exklusionskriterier var muskuloskeletala besvär, hjärt? kärlsjukdom, KOL, RA, Gonartros eller pågående infektion. Isokinetisk benstyrka mättes på 25 försökspersoner >60 år i Biodex System 3 och isometrisk handgreppstyrka mättes med Grip-D.

Personer med vissa kognitiva funktionsnedsättningar har ibland svårt att använda en vanlig webbläsare. Detta gör internet mindre tillgängligt för denna grupp. Med hjälp av en anpassad webbläsare med förenklat gränssnitt och funktionalitet finns förhoppning om att användarvänlighetsbarriärer för internetanvändning hos dessa personer skall minska och att användningen skall kunna vara mer självständig.Som teknisk målplattform används Microsoft Windows med Internet Explorer och utvecklingen genomfördes inom .NET med C#. Ett mål med den tekniska implementationen var att till så stor del som möjligt utnyttja redan installerad programvara på målsystemen och därmed minimera behovet av programuppdateringar, vilket skulle göra programmet mer framtidssäkert, samt minimera mängden administration av programmet. Tester genomförda på Västmanlands läns landstings Datatek på Handikappcentrum i Västerås gav positivt resultat.  Användarna kunde fokusera på de webbsidor de besökte och personalen kunde snabbt ställa in programmet för användaren..

Vid bedömning av allmän daglig livsföring (ADL) försöker man analysera hur en människa med fysisk och/eller psykisk funktionsnedsättning kan utföra olika aktiviteter i det dagliga livet, såsom personlig hygien, matlagning och städning. Arbetsterapeuter utför den subjektiva bedömningen med hjälp av standardiserade checklistor. I vissa fall ger inte det en tillräckligt nyanserad bild av en persons förmåga och det finns behov av bättre ett system som kan användas vid ADL-bedömningar av personer med olika typer av funktionsnedsättning.Målet med detta projekt har varit att ta fram ett mobilt system för aktivitetsbedömning anpassat för hemmiljö. Systemet är uppdelat i två delsystem. Delsystem 1 består av en mobiltelefonapplikation anpassad för Android som tillsammans med en rörelsesensor registrerar aktiviteten hos en person.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

Denna rapport inriktar sig till ett mindre företag som vill tillhandahålla en egen fjärrbackuplösning. Backupen ska göras från en server placerad i företagets lokal till en lagringsenhet i någon av ägarnas hem med hjälp av VPN-förbindelse. För detta krävs ett program som har stöd för att göra uppkoppling automatiskt via VPN på en Windows 2008 Server, 64-bit plattform. Utöver det ska kryptering, komprimering och funktion för full och inkrementell backup finnas tillgängligt i programmet. Fyra fjärrbackupprogram har därför utsetts för jämförelse av hur de kan lösa företagets krav.

The aim of this thesis is to examine how thesauri constructed with latent semantic indexing LSI are performing when used for query expansion. There is a well-known problem with synonymy in information retrieval and one solution to this problem is to use a thesaurus. In this thesis thesauri are created automatically to find statistically related words and not only synonyms. LSI is a method that uses singular value decomposition SVD to reduce dimensions in a matrix and find latent relationships between words. We constructed nine thesauri and used them for query expansion in a Swedish database, GP_HDINF.

Can the Danish "Aftalesystemet", a system with the intention to simplify the use of services within health care, be used in Sweden? This project has investigated the possibility by installing and testing the system and explored its functions to detect any eventual problems. Analyses were made of the system's graphical part and the underlying code to see in greater detail how the communication between units occurred, since no actual documentation of it existed. Discussions with the developers took place regarding how the current system works and how further development should continue. In order to test the system, a completely virtual environment was used.
