The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

Denna uppsats är en studie av två delar i konstnären Sara Jordenös dokumentärinstallation Personaprojektet. De båda delarna bär titeln ADR respektive The Set House (Hedvig). I undersökningen genomförs en kritisk diskursanalys vars fokus ligger vid frågor rörande konstruktioner av verkligheter och hur språket påverkar och påverkas av normer för klass, genus och sexualitet. Frågeställningarna innefattar funderingar rörande hur kategorisering av människor sker, hur individer formar sig själva som subjekt och hur dessa aspekter belyses i det utvalda materialet. Analysen undersöker även upplevelsen av verket, och hur val av medium bidrar till denna..

The purpose of this thesis was to examine relevance of the proposition made by new insitutionalists about institutional and technical environment. This proposition originaly made by Meyer & Rowan (1977) has two core assumptions: The first is that all organizations are controlled by combinations of types of demands; technical demands for efficient production and institutional demands to adept to cultural and normative expectations. The second assumption is that there exists a few organizations dominated almost entirely by one typy of demand. Organizations dominated by institutional demands are said to live in an institutional environment, while technical organizations is said operate in a technical environment. This thesis has examined if these assumptions are still applicable in describing organizational interaction with the environment.

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

I have been studied Microsoft SharePoint on behalf of Prevas in Karlstad.The purpose of my work was to see if Microsoft SharePoint was what Prevas wanted as a replacement for the existing intranet, which they are not satisfied with today.My work was a kind of foundation for Prevas so they could make a decision in this matter.The work began with installing SharePoint at one single server at Prevas. We used a virtual technology (VMware) at the installation, which can be described as that we created two ?miniservers? in a bigger server, one for SharePoint and the other for storing the information. This kind of technology is strongly advancing. The main work consisted of setting up the structure for the navigation and designing both the portal and the local homepage for Prevas Karlstad.

Abstract This study is an evaluation of a development project, seeking to work for entrepreneurial learning, starting from John Hattie's findings on the significant factors for visible learning. The study is based on action research a method together with a questionnaire, focused interviews and observation, by the issue of How do students perceive entrepreneurial learning? The results show that the methodology contributes to a more active learning and greater work satisfaction among students. The results also reinforce the thesis of the formative assessment and the importance of reflection for increased metacognition. The work identifies the project's educational shortcomings and strengths, and lays the foundation for further development towards full implementation of entrepreneurial learning in a secondary activity that works to prepare students with special needs for the labor market..

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems.

Syftet med vårt examensarbete är att undersöka hur passivhus eller så kallade nollenergihus skiljer sig i funktion samt uppbyggnad från konventionella hus.I vår undersökning tar vi upp hur utformning, orientering, material samt ett väl fungerande klimatskal påverkar energiförbrukningen.Vi har tittat närmare på faktorer som sparar energi samt hur ett typiskt passivhus är uppbyggt. För att se hur teorin fungerar i praktiken har vi tittat närmare på befintliga passivhus, nämligen de på Oxtorget i Värnamo.Vi har kommit fram till att passivhus fungerar och vi anser det som väldigt viktigt att man fortsätter driva fram arbetet och informera om dess betydelse för miljön.Passivhus blir mer och mer uppmärksammat. De är något dyrare att bygga, men man tjänar in det i längden. Lönsamheten är dock inte det viktigaste utan känslan av att man gör något bra för miljön..

The main objective of this paper has been to construct a way to measure the level of social capital in a society. Based on a theory which describes the ideal society have I herein tried to find out to what extent the Swedish and Danish communities correspond to this model. The theoretical foundation consist of several different levels of analysis, and I have indeed found there to be consideral differences between the two nations on these different levels. The paper however conclude that these differences even out to add up to a Social Capital Index that is remarkably similar. A result which is to be interpreted as one nation being about as close to the ideal situation from a social capital point-of-view as the other..

In several scientific and technical educations today we meet mathematical studies in differential- and integral calculus. The classic mechanics is a foundation for the physics and it has made it possible for today's technical developments that we in our everyday life meet and make use of. The intention for this essay is to give a picture of the person behind this discoveries that changed the science and the world. Besides the purpose to bring the reader on a journey through Isaac Newton's life the main intention is to give an understanding of the way he discovered the binomial theorem, the differential- and integral calculus, the numerical methods Newton-Raphson's and Newton's interpolation-polynomial, Newtons identities and his classification of third-degree curves and elliptic curves. A derivation of Kepler's first law is also included..

The foundation for a museum is the collection. To collect, preserve and display is what constitutes a museum. But the process of deciding which object´s should be saved, and which objects should not, are based on values. It is also values that make people inclined to donate objects to museums. How and why we value a museum determine if and why we donate.Objects themselves could be said to have a biography just like people.

SammanfattningMuseer har till uppgift att dokumentera, forska och samla in människans och naturens lämningar för att berika kulturarvet och bidra med ny kunskap. Frågan är vad det är för kunskap som förmedlas och vad det är som väljs att ta med i kulturarvet. Denna uppsats syftar till att lyfta fram diskussionen kring huruvida kulturarvet och kunskapsförmedlingen är könsneutral och hur den dolda genuskonstruktionen speglas i utställningarna samt att studera hur ett genusperspektiv används och integreras på Tekniska Museet i Stockholm och Malmö Museer. Som empiriskt underlag ligger kvalitativa intervjuer med sammanlagt 8 representanter från båda museerna. Den teoretiska basen består av teorier kring kultur, kulturarv och genus.

Denna rapport beskriver och undersöker olika sätt att använda online 3D i webbpresentationer. 3D ställs emot vad som ibland brukar kallas 2,5D (Man fotograferar en produkt ur olika vinklar för att få en serie med bilder som kan ge en fiktiv 3D upplevelse).

Målgruppen är programmerare och webbutvecklare som tar fram material för små och medelstora företag..

Urbanization and the flight of the creative class drains the countryside when it comes to creativity and talent. Especially the young leave sleepy societies. Richard Florida claims that the city attracts the creative class and enables for economic growth to flourish. Robert Putnam adds to the picture by saying social capital might be equally effective as nourishment for growth. In Uddebo, a rural village in the south of Sweden one combines the two creating a vivid society where creativity flies high and ideas fertilize each other?s.

No matter what subject or which grade you are active in, the teachers in Sweden have incommon that they are provided with governing documents that states the guidelines and goalsregarding each subject. Along with these governing documents every teacher has to findmaterial that will be used as the foundation of the teaching. This thesis is a study of howSwedish history teachers define what material they are going to use in their teaching, andwhich the factors are that is affecting these choices. The question whether a child?s ethnicaland cultural background is a factor that affects this choice of material is concerned, as well aswhat is current in Sweden and the world.
