This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

A constantly increasing number of magazines are using the Internet as a business channel. One of these is Allt om Mat (All about Food). Together with expressen.se, Allt om Mat developed a food website, alltommat.se, which was introduced at the beginning of 2008. In this essay we investigate how alltommat.se developed its service concept. Further, we look at how this development has influenced and been influenced by relations among the three actors and the users.

A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.

Abstrakt  Tv-branschen är en jätteindustri som styrs av ett fåtal stora sändningsnätverk. I Sverige är den största distributören Sveriges Television (SVT) och på grund av detta så är sannolikheten att personer som arbetar inom ljud i Sverige någon gång kommer att arbeta på projekt för dem väldigt hög.I min uppsats har jag utfört en Actor Network-analys av empiriska studier jag utfört på postproduktionsbolaget Europa Sound and Vision. Med hjälp av analysen vill jag undersöka vad begreppet ?god hörbarhet? består av och därmed kunna definiera uttrycket tydligare.Jag jämför sedan SVTs syn på hörbarhet med den jag fått fram genom dessa studier för att till slut ändra på den nuvarande synen och på det regelverk SVT har..

Companys usually have intern communication platforms where employees can gather information and communicate with eachother. These networks are not public which leads to less resources spent on development. If this network is also used as a work tool may inadequate usability decrease work effeciency. Thats why we, by using known design principles, evaluated an already existing network of this kind along with interviews and think out loud tasks for users. Four users had to do some tasks while they explained how they went through step by step to solve those. This report culminates into a couple of guidelines which can be used to create a user friendly network. The problems that prevented users to feel in control when working resulted in the following guidelines: Create shortcuts of frequently used functions.

This project consists of an adaptation, trial and evaluation of a model for practicing. Based on prior research I created a model aiming mainly to raise a musician?s self- awareness around the different parameters a performance consists of. An additional wish was for it to simultaneously assist the musician in monitoring his or her progress. With video recording and self-evaluation as the two main parts I tried the model by using it over a period of three months.

In this report a model was constructed in order to determine how a number of covariates influence the gross domestic product, GDP. The covariates were chosen depending on their expected influence on GDP, for example education and life expectancy. The data used in this report are collected from the World Bank. The model to describe GDP has been calculated using multiple line arregression. In order to reach a reliable final model the number of covariates has been gradually decreased to eliminate insignificant covariates.

Author Cocitation Analysis (ACA), multidimensional scaling (MDS) and Social Network Analysis (SNA), has been used to analyze and visualize the invisible college of the journal European Union Politics. The concept invisible college was first introduced in the fifteenth century, through the creation of the ?the Royal Society of London?, and it was reintroduced in the 1960:ies and the 1970:ies by scholars such as Price and Crane. It is said to have been interpreted in as many ways as there are authors who have used it. Here it has been used synonymously with the term citation network.

The aim in the study is to search for a deeper understanding of how parents experience a neurological diagnose of the child and how this affects the parenthood. Parenthood was seen in a systemtheoretical perspective as a social construction. The narrative method was used in two lifestory parentinterviews. The analysis was made from parenthood. The result formed stories about parenthood with children having neuropsyciatric functional disability who even came to be a woman?s struggle.

Purpose:mental illness and the effect it has on individuals social network and relationships, and vice versa.The purpose of this study is to shed light on the rarely mentioned subject of severe Method:analysis was performed on a total of 15 interviews, which consists of three individuals with severe mental illness. The focus of the study was the subjects? description of the social network, excluding clinicians and other professionals.This study is inspired and conducted in a Grounded Theory manner. A secondaryFindings:may it be with specific individuals or groups. They describe the importance of surrounding themselves with people who do not judge them and it is through them they get validated.Places have been emphasised as having special meaning for the social interaction and overall wellbeing for the subjects.There is active actions for social interactions/relationships taken by the subjects,Conclusion:their social network.

Network RTK is a real-time technique for accurate positioning with Global Navigation Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be transferred seamlessly to the user in real time. Commonly the corrections are transferred via mobile phones. The Swedish National Land Survey operates a nationwide Network RTK service, where users can receive correction data via GSM or mobile Internet (GPRS).

This is a bachelor thesis, written at the business studies institute, Uppsala Unviersity, exploring how digitalization has affected the Swedish book industry. This is done by studying how the introduction of the e-book has changed the way the publishers work and what problems and opportunities arise with the new way to publish and consume books. The technology optimists, that existed around the turn of the millennium, when the e-book came, made predictions along the lines of the physical book having ceased to exist within five to ten years. But the physical paper books do very much still exist, so haven?t the change happened as predicted? The purpose of this thesis is as follows: How has introduction of the e-book affected the relationship between the Swedish publishers and the book as a whole? This means that we consider the book as a concept, as a resource or product, and study how a change in this product affect publishers.The theoretical framework used is basically classical network theory.

Many studies have been conducted of different types of business networks in recent years. Despite this, there is a lack of research concerning industry-transcending formal networks which are limited to a specific region. We have conducted a case study of Örebro Promotion, which is an industry-transcending network including over 500 members. Örebro is a medium-sized city in the middle of Sweden. The purpose with our study is to create an understanding of why enterprises choose to be a part of the network and what they feel is the gain of their membership.
