The purpose of this thesis is to examine and present the oportunities of solvingcontrol problems using Modelica. This is done by creating some Demonstrationexamples with exercises. These examples should cover as many types of controlproblems as possible. The exercises are aimed for people with basic knowledgein modeling and automatic control engineering but with little or no knowledgein Modelica. There are different types of Modelica implementations and the onesused in this thesis are OpenModelica and MathModelica..

Aim: Auditors objectivity is an obvious part of auditing, but there is doubts and hesitation in society today because of the corporate scandals that have occurred in recent years. Several researchers suggest that auditors actions and behaviors is connected to the ethical climate within the organization. A relationship that also affects auditors objectivity and independence. This thesis aims to investigate how the ethical climate influence auditors choice of relationship to their clients, by choosing a relational and close relationship or a transactional and distanced relationship. And if the client approach have an effect on the auditors objectivity.Method: A survey was conducted among 232 certified accountants in Sweden.

The following paper is a study about how three Swedish workingclass news papers, Arbetet, Norrskensflamman and Ny Dag, describe and stigmatized the common strike braker in may 1931. I chose in particulary this month because of the tradgic events in Ådalen 14th of may 1931, where five citizens got killed by the Swedish military during a friendly Demonstration and the strike braker was a part the unrest that was embossed among the organized workers in Sweden..

This thesis is about the effect of political efficacy on societal participation among youths aged 15 to 29. It takes a starting point in the gloomy view of the decline of political participation among citizens in the western world, especially pointing out youths as a threat to democracy. This is a broad subject to take on so my aim becomes a bit more specific. The aim of the thesis is therefore to investigate if belief in ones own capacity and in the responsiveness of the political system affects the actual participation among youths in Europe, independent of a set of alternative predictors. Moreover the thesis is divided into two sub-investigations, one qualitative and one quantitative.

Vårt examensarbete går ut på att utforska processen kring att producera en artist och sedan presentera denne för skivbolag. Till grund för detta arbete ligger vår förra studie, ?Hur ser musikproducentens roll ut inom svensk populärmusik? och resultatet av den studien har vi i detta arbete omsatt i praktiken. Vi har nu arbetat med ett case, vilket bestod i att producera en sångerska och sammanföra hennes låtar till en homogen produktion för att slutligen presentera denna för två svenska majorskivbolag. Vid presentationen förde vi en diskussion med respektive A & R angående både vår presentation och artistpresentationer i allmänhet.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for Demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

This thesis describes the process of developing a reservation system for common resources through a TV-interface. The system is developed in cooperation with the company Dreampark and is built to work in their platform for TV, Dreamgallery. The main goal was to develop a reservation system and to make it work with Dreamgallery, to develop a Demonstration version of the system. The thesis describes the approach for developing an easy-to-use and customisable program and interface for making reservations. How this is inserted into an existing program in a suitable way.

Detta examensarbete har genomförts på uppdrag av Totalförsvarets Forskningsinstitut. Examensarbetet är ett av fyra delprojekt i projektet Telekommunikationer för strid i urban miljö. Projektet syftar till att ge förslag på metoder och utrustning som kan underlätta för soldaten på taktiskt nivå, i Försvarsmaktens insatsförband, genom att förbättra informationsinhämtning och -överföring.Syftet med examensarbetet är att i en praktisk Demonstration visa nyttan med MIMOsystem antingen genom ökad kapacitet eller genom ökad tillgänglighet.Examensarbetet är uppdelat i tre olika delar: förstudie, utveckling av teknikdemonstrator i hårdvara samt Demonstrationer och presentationer. Demonstratorn är byggd medGNU Radio mjukvara, som körs på två Linux-maskiner, med Universal Software Radio Peripheral som RF hårdvara. För att visa fördelarna med MIMO har spatiell diversitet implementerats i en mottagare.Implementationen visar att bitfelshalten reduceras till en tredjedel jämfört med en SISOmottagare..

Modellen är ett kraftfullt redskap i designprocessen. Inte bara på grund av dess pedagogiska värde vid en presentation eller Demonstration av något, den är även ett värdefullt verktyg i designprocessens tidiga stadier. Jag har byggt en modell och använt den som ett skissverktyg när jag utformat flera olika förslag på utformning av en trädgård i en norrsluttning. I metoden beskriver jag hur jag konstruerat modellen och hur jag gått till väga när jag använt den i min designprocess. I resultatet redovisas de olika förslagen och idéerna jag kommit fram till med modellen som redskap. Genom att inte bara kunna se utan även känna höjdskillnaderna och formerna i trädgården med mina händer så har modellbyggandet hjälpt mig att förstå platsen på ett bättre sätt och det har hjälpt mig att utforma och presentera sex olika förslag på utformning av trädgården som jag redovisar i det här arbetet..

Alla lärare jag intervjuat anser att laborationerna framförallt ökar förståelsen av abstrakta begrepp inom ämnet. En Demonstration är bra typ av experiment eftersom en sådan kan göra en lektion mer intressant och nyttig för eleverna men det är också viktigt att eleverna laborerar själva och får laborativa färdigheter. Lärarna använder sig mest av slutna laborationer i sitt arbete och det kan förklaras med vanan att genomföra sådana och att öppna laborationer är betydligt mer tidskrävande. Fördelen med slutna laborationer är att de lätt kan belysa hur någonting fungerar i praktiken. Nackdelen är att de inte är så stimulerande för elevernas tänkande och utveckling.

Automationscenter & Bråvalla Elteknik AB is a company that offers the market completed total solutions where the customer can operate and monitor their production from the terminal. In these total solutions they lack standard circuit which are developed by the company and which could manoeuvre/control/monitor controlled process objects. This report defines the work of developing the most common standard circuits.The report is initiated by a short theoretical part about PLC and the PLC system, with a connected terminal, which has been used. Thereafter, the turnout of the demands of specification is reported, after discussing with the supervisor in the course of the project. The report concludes with a disclosure of how the programming, the documentation and the testing have proceeded and a final discussion concerning the project and proposals on continuation.The result is a CD with the documentation of standard circuits and how they are implemented in a new project.

Ungernrevolten 1956 var en kort intensiv revolt som varade i tolv dagar där ungerska frihetskämpar revolterade emot det kommunistiska styret i landet En relativt lugn Demonstration startad av ungerska studenter växte snabbt och ledde snart till en väpnad revolt emot den ungerskkommunistiska regimen. Några dagar av reformer mot ett liberalare ungerskt statsskick avbröts abrupt av de ryska trupperna som efter tolv dagar slog ned revolten och återtog makten i landet igen. Denna studie syftar att genom fem svenska dagstidningar med olika politiska tendens undersöka Ungernrevolten 1956 och hur den behandlades i de olika dagstidningarnas ledarartiklar. Ledarartiklarna analyseras med hjälp av Vedungs (1971) modell som används för att kartlägga politiska debatter. Resultatet visar att det finns klara skillnader mellan de olika tidningarna hur de presenterar revolten, man kan även se vissa samband till deras politiska inriktning..

In the year of 2006 I moved to South Africa for a year, a land that has fascinated me because of its history. During the time of my stay I became very surprised how strongly apartheid permeates the community where the white South Africans today are building walls around themselves. Through media we get surrounded with pictures that media creates and to find information regarding what?s happening in the world this is, most often, the primary source. Therefore I believe it?s interesting to explore how two different local newspapers from the county of Kalmar, with two different ideologies, present pictures of the same event, namely the revolt of Soweto in 1976 and how these two newspapers relates to racial policies.

Scania provides a fleet management system for hauliers who want to control their fleets in anefficient way. The system includes an onboard computer with touch screen called ScaniaInteractor where the driver can access GPS navigation, order support, message service and otherfunctionalities. The purpose of this thesis is to develop a concept for logging the user interactionon the Interactor and analyze the result which enables further development and optimization ofthe interface.A Demonstration application is designed, implemented and tested for the purpose of showing thepossibilities and difficulties with logging of interaction. The result shows that logging is quiteeasy to implement and that the amount of produced data is small and therefore not expensive totransfer via GPRS to a central server where searching and analysis can be done. On the otherhand, the biggest challenge lies in the analysis and interpretation of the logged data and to applyit to the development of the interface.
