Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

This paper describes the development of direct and indirect service at the former Gothen­burg city library. This was during this period of time not the public library of the town, but a scientific library mostly serving the college, although also open to the public. Furthermore the services offered in Gothenburg are compared with those of the two old Swedish university libraries in Uppsala and Lund. The investigated direct serviceforms are "making material available", "guidance", and "localities". The indirect service areas are "the catalogue" and "the personnel and their competence".The conclusion is that the differences weren't that big and that Gothenburg city library was a modern library providing about the same services as you could find in Uppsala and Lund.

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

In the current situation in the housing market and in particular the inner city much attention is directed towards achieved prices per square meter in sales. The indicator is as a principle an appropriate measure of the housing market?s health and development, and can to some extent be used to make approximations of the general economic health status of municipalities and counties. It occurs occasionally that questions about whether prices are based on fundamentals at all times.The thesis questions that very issue, not from a macro accompanying financial perspective but rather from a microeconomic perspective, where each tenant ownership in the study is a micro-object. Are the observed prices per square meter rational relative to housing cooperative?s assets or is there a lack in the observed prices anchoring the respective association's finances.

Today, buildings utilize 40 % of the total energy consumption. New energyrestrictions and directives have entered the construction industry. Photovoltaic is asustainable, clean and quiet solution that integrates well in the urban environment buthave not yet reached a breakthrough on the Swedish market. The conditions for solarenergy production are often set in the early planning stages where they rarely arebeing prioritized.This master of engineering project focuses on identifying problems regardingimplementation of photovoltaic in city development projects and giving suggestions topossible improvements in the planning- and construction process. It also givesrecommendations on how the conditions for energy production can be optimized inthe early zoning stage.By conducting simulations with PVsystV5.21, on three ongoing city developmentprojects in Umeå, Malmö and Stockholm and by carry out and analyzing interviewswith city planners, constructors and architects, some conclusions have been made.Several improvements, both politically, with changes in the subsidization systemand/or instatement of a new law with feed-in tariffs, and within the solar- andconstruction industry itself, with better communication between different parts of theprocess as well as better use of experience, can be made.

The purpose of this study was to find out what different groups of visitors do when they are at Borås City Library. Three issues were formulated from the purpose and they were: What do users do when they visit the City Library in Borås? What occupations do those who visit the library have? What similarities and differences are there in the use of the library depending on the visitors? occupations? To answer these questions a questionnaire was handed out among the visitors at Borås City Library. The theory that was used when the material was analyzed comes from the book?Gør biblioteket en forskel?? and the book is written by Henrik Jochumsen and Casper Hveneegaard Rasmussen.

This essays overarching aim is to contribute to the theoretical discussion of transformation processes that are shaping the urban landscapes and further to problematize contemporary planning discourses in Sweden. Drawing on the concept of Foucault?s heterotopia and actor-network theory for spatial analysis, the paper seeks to analyze the complex urban landscape transformation process as an emergent property of human and non-human actor-networks seeking to transform and order space. With the district of Rosenlund in Gothenburg as a starting point, this thesis intends to examine how the cultural infrastructure - used by the residents and visitors of the city - are related to the city's planning and development processes. The case study is based on a boat (Rio Rio) in Rosenlund canal that is defined as a cultural infrastructure.

The aim of this study was to describe how adolescents experiences their quality of life, and tocompare if there are any differences in how they experiences their QOL depending on wherethey live, big town or smaller town. The aim was also to examine how adolescentsexperienced their schooling. The study is empirically, quantitative with a descriptive andcomparative design. To measure quality of life a tried and tested instrument ? LifeSatisfaction Questionnaire (LSQ) was used.

How do we perceive literature? In our times computer games and Internet have made us grow more comfortable to the usage of non linear storylines. But how does this apply to printed literature?In this essay, called ?From a to b through d h and o. Non linear storytelling in our time? I have focused on nonlinear literature from different time periods and I have studied novels such as James Joyce?s Ulysses as well as works by William S.

In the urban planning debate of today, two strategies for city development stand out as each other's opposites, urban sprawl and smart growth. This thesis concerns a development project of the latter kind and aims to give an alternative proposal to new buildings and a park in a Swedish city block. The term sprawl is used for new developments on virgin soil on the outskirts of cities leading to a city spreading, while smart growth stand for increased city density through development on re-used land within the city boundaries. The latter are often seen as more sustainable in many levels and are also shown to have positive effects on a number of city functions. At the same time smart growth has negative consequences on other aspects of the city such as public open spaces.

Climate changing is a growing problem for many countries and communities over the world. The cities has a huge work to deal with in their reforcements of their cities to be resilient ones. This thesis makes an effort to investigate and illuminate some of the problem the cities has to solve related to flooding, hazards, erosions, rising sea levels and crotches. This thesis will help to find solutions that international and national efforts has produced and handed out to each other. A lot of communities are charing their excellent tools that works for them.

The management at the City of Stockholm?s Sports Department have problems. During recent years several IT-projects have been launched but results are worse than could have been hoped for. The projects are generally perceived as being too expensive, too time consuming and not to have delivered the expected results. This thesis aims at giving the City of Stockholm?s Sports Department theoretically based advice on how to improve their management of IT-projects.

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

This project includes a small study of Västerås city's housing needs, and a proposal on theuse of the property 1:207, Lantmännens silo in the Eastern Harbour, Västerås.The project intends to produce a basic study of the useful systems for this rebuilding projectwith regards to sustainable development and energy saving light buildings.The end result, which consists of a detailed visualization of the proposal, intends to becomean iconic natural focus for the Eastern port of Västerås and an example of the use andadaptation of existing structures.The property must also link the eastern parts of Västerås with the center through anextension of Mälarleden.The work has been performed through literature studies, site visits, contacts with the City ofVästerås and by calculations.The proposal consists of architectural proposals drawings and visualizations.Furthermore, a suggestion is given of how the property can be used and fitted into theoverall plan for urban density development currently underway in the city of Västerås.Computer programs used have been Microsoft Office Excel, AutoCAD and ArchiCAD..
