Idag används BIM, byggnadsinformationsmodellering, i fler och fler nybyggnadsprojekt och det finns mängder med information att inhämta om detta både i tryckta tidskrifter och på internet. En obesvarad fråga är dock hur arbetsgången ser ut när BIM ska användas i ombyggnadsprojekt. Informationen som går att finna om detta är begränsad trots att ombyggnadsprojekt utgör en betydande del av byggverksamheten, såväl i Sverige som internationellt. Målet med denna rapport är därför att undersöka hur ombyggnadsprojekt i dagsläget utförs med BIM som arbetssätt. Processen att arbeta med BIM har undersökts i detalj för att klargöra hur den ser ut idag och för att identifiera den problematik som just ombyggnationer medför.

Global warming is going to affect our society in many ways. One can say that the problem we face has two different sides. One of those sides has received a lot of attention, namely how we can reduce our emissions of greenhouse gases. However, because of the climate system's inertia the climate will continue to evolve over a period, no matter how much we will cut back on emissions. Because of this, we have to start adapting our society to the climate changes that we cannot influence.

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.

Costs of maintenance on agriculture machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture machines, for example STANK and JTI machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Förslag på hur Arkitekturskolan kan ritas och programmeras om för att bli en offentlig byggnad i staden som ger mycket tillbaka till Stockholms invånare. Form och program är utformat att ge alla som befinner sig i och utanför byggnaden en ny syn på staden där inte bara gatuplan är offentligt och takplan är privat. Runt byggnaden slingras sig en offentlig promenad som leder upp till det öppna takplanet med bra utsikt över staden. Byggnaden har delats upp för att skapa torg på plan 2. GA är en offentlig plats likt en galleria 2.0..

The overall purpose of this essay is to study in which degree the democratic model that is called participant democracy works in the Swedish municipalities. To achieve what I set out to do I will focus on a central political area in which the Swedish municipalities has sovereignty versus the state, in other words in an area where they rule themselves. That political area will then represent how well the participant democracy works in the Swedish municipalities. The research questions then becomes:Does the participant democracy at Swedish Municipality level work in a satisfying way?Does the participant democracy in a large Swedish Municipality in a central political area work?Does the participant democracy in a small Swedish Municipality in a central political area work?Are there similarities and differences between the municipalities?If so, how can that be explained?To answer these questions I will study documents regarding the planning and building area.

This master?s thesis investigates in which ways students seek out and access their textbooks and how they use their university?s library in this process. Data is collected through interviews from six students several semesters into their studies at the University of Stockholm. For the interviews two students each were selected from the fields of law, economics and humanities. The empirical findings were analyzed using T.D Wilson?s model of information behavior (1997).

AbstractTitle: When book becomes film... ? a comparative analysis of the book and film Catch me if you can (När bok blir till film?En jämförande analys av boken och filmen Catch me if you can)Number of pages: 46Author: Majlinda JunikuTutor: Amelie HössjerCourse: Media and Communication Studies CPeriod: Autumn term 2007University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: To study what model of dramaturgy belongs to the film Catch me if you can and to see what has been crossed out, altered and added from the book so the narrative will fit this model.Material/Method: The film Catch me if you can and the book with the same name has been used to analyze the differences between them. I have divided the differences into three categories: Crossed out, Altered and Added. In the analysis section these have been presented in each section of the film.Main results: Catch me if you can is definetly a film made with the design of the Anglosaxon model, mostly because of its timestructure and that it portrays an action and not just a condition which is normal in the epic-lyric model.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

 Abstract  Interest in Lean grows and spreads to the public from industrial and service sectors. Lean is currently used in administrative processes and it is called Administration but can administration be Lean? The aim of our study is to develop a useful model for a successful implementation of Lean Administration by using various scientific articles, books and information from the case study.The part of the purpose is to: ? Identify critical success factors that arise? Identify the challenges arising from the implementation of Lean Administration.We have studied a Division within Distribution at GE Healthcare in Uppsala. The model that we have developed provides challenges and success factors for a successful implementation.In order to succeed in implementation, a culture that promotes continuous improvement must exist in the organization. A key success factor is to understand Lean Administrations structure and principles.

In the EU there are EC Directives that Member States of EU should follow. Sweden has undertaken to transpose EC Directives regarding the working environment to Swedish Provisions.  In 4 April 2006, the European Commission had some criticism against the Swedish implementation of the Construction Sites Directive. The Swedish Work Environment Authority has in response to this criticism reworked the Work Environment Act and related provision about building and civil engineering work. The changes came into force 1 January 2009.These changes have resulted in some working methods and even new responsibility subjects must be reviewed. The purpose of this exam project was to investigate if contractors and clients in the construction sector, had have time to update themselves on this front and adapt to these changes.
