District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

This thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures. The main objective of this part is to clarify the contrasts between Iranian and Swedish cultural, social, linguistic and family structures, and also the characteristics of the crisis that most immigrants go through on their arrival in the new country. The qualitative method also involves structured telephone interviews with eight highly educated Iranians.This method was supplemented by a quantitative study through questionnaires of the attitudes· of lranian immigrants to libraries and reading. Iranians in Sweden turned out to be frequent Iibrary users.

I takt med att inköp har fått en allt mer betydande roll inom företag krävs det också att strategier för inköp utformas på ett sätt som möjliggör att de kan efterlevas och följas upp, framförallt när det rör sig om koncernövergripande strategier som kräver samordning. I dagsläget är det inköpsrådet på Saab som styr över och samordnar projekt och initiativ som sker inom inköp. Inköpsrådet ansvarar även för framtagandet av inköpsstrategier och arbetet utifrån dessa för hela koncernen. En första klassificering av Saabs leverantörer utefter Kraljics matris genomfördes år 2010 och i samband med detta har ett ökat intresse påvisats för att på ett differentierat sätt mäta och följa upp leverantörer. Syftet med studien är därmed att se vilka Key Performance Indicators (KPI:er) som är tillämpliga i en indelning av leverantörer enligt Kraljics matris, det vill säga om olika KPI:er är fördelaktiga för att genomföra mätning och uppföljning av olika typer av leverantörer enligt Kraljics matris.En betydande slutsats med indelning av KPI:er enligt Kraljics matris är att studien ska påvisa vilka mätetal som är mest väsentliga att ha vid uppföljning av leverantörer kopplade till respektive kvadrant i Kraljics matris.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

The research objective of this thesis was to conduct a holistic evaluation of an operational information system. By holistic evaluation we mean that an equal focus was placed on both the system system perspective and its users user perspective, in the actual environment where the system and its users function contextuality. In addition, the methodological objective of the study was to test a new research approach in a real life setting. The participants of the study were twenty newspaper journalists employed at Göteborgs-Posten GP. The information system NewsLink is a manually indexed full-text database containing all articles published in GP since 1994.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

This thesis processes the work of developing CPU code and GPU code for Thomas Kaijsers algorithm for calculating the kantorovich distance and the performance between the two is compared. Initially there is a rundown of the algorithm which calculates the kantorovich distance between two images. Thereafter we go through the CPU implementation followed by GPGPU written in CUDA. Then the results are presented. Lastly, an analysis about the results and a discussion with possible improvements is presented for possible future applications..

In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures. Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.
