Adaptiv temperaturreglering av bostadshus
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.
Jämförelse mellan hundskolans och Svenska Brukshundklubbens kursdeltagare i Skaraborg :
The aim with the present study was to investigate whether there is a difference between the course participants who find their way to the dog-school respective the Swedish Working Dog Association. The study have focused on four issues; why the course participants have chosen the dog-school respectively the Swedish Working Dog Association, why the participants bought their dog, if the participants are satisfied with their dogs and if it is more likely that they turn to the dog-school?s than to the Swedish Working Dog Association with their first dog?
Course participants from two dog-schools and from two of the local clubs belonging to the Swedish Working Dog Association in Skaraborg, Sweden, answered a questionnaire. In total 85 answers were collected, including 60 from the course participants from Swedish Working Dog Associations and 25 from the dog school?s course.
Konkursprognostisering : Tillämpning av en konkursprognosisteringsmodell på små svenska aktiebolag
Bankruptcy is a problem for the society in form of high costs for including suppliers, customers, employees, investors, banks, insurance companies etc. The purpose of this study is to confirm or dismiss a bankruptcy prediction model that has been developed in a previous Swedish study, in order to predict bankruptcy with help of specific key figures. The model has only been tested in a larger perspective where the population consisted of all small firms in Sweden, in this study the model´s reliability is tested by that it instead been applied to a minor perspective, where the population only includes Stockholm. With a quantitative approach of 12 different key figures from a total of 60 Swedish smaller registered companies in Stockholm between the years 2005-2007, has been studied. The companies are divided into two groups, companies with good financial health and companies that have ended up in bankruptcy.The results shows that the model is applicable in a smaller population, but some of the key figures do not generate essential or any type of information about bankruptcy, but the majority of the key figures in the model did.
Prediktion av bostadsrättspriser i Stockholms innerstad.
A frequently asked question in real estate marketing is at what time of the year it is optimal to invest or sell. The aim of the project was to answer this question and to generate a prediction model over real estate located in the centre of Stockholm that takes seasons into account. With acquired sales statistics in Stockholm between 2010 and 2013 it was possible to perform a linear least square regression, also known as Ordinary Least Square (OLS), with describing qualities and season of sale as parameters. Statistical problems such as Multicollinearity and Heteroskedasticity have been taken into account when deriving the model. The result was a highly accurate prediction model indicating the profitability of investing in real estate during the summer and selling during the autumn..
En klimatanpassad järnväg : Långsiktig planering av infrastruktur i ett föränderligt klimat
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.
Informationsanskaffningsbeteenden hos oetablerade arkeologer
The purpose of this study is to examine the information seeking behaviour among unestablished archaeologists. Special attention has been directed to the areas of informal communication and the development of personal networks. As a former archaeology student I have been able to apply my previously acquired knowledge when writing this thesis. The empirical study is based on nine interviews with archaeologists each with more than one and less than four years of professional experience. They all have various experience of working as a fieldarchaeologist and five have simultaneously worked as university researchers.
Integration av simuleringsmodeller för bränslesystemet i JAS 39 Gripen
In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.
Är BIM lönsamt vid projektering av ett småhus?
This report brings up the question - ?Is BIM profitable when planning a single-family home??.The methodology for finding the answer to this question is firstly to state the definitions of BIMand the company that is projecting by using the BIM-model. The answer is then obtained byanalyses of the factors of profitability with respect to: time, opportunity of revision, problemvisualization, preference adjustments and energy. A BIM-model has been made simultaneously asthe writing has proceeded to get a perception of how a BIM-model really matters for the analysis.The analysis shows that the answer for the question depends on further factors. The factors thatare mostly discussed are the company?s intentions and the complexity of the house.
Arbetsvillkorens samband med sjukfrånvaro och sjuknärvaro : En studie av hemtjänstpersonal
Sickness absence is a measure of health and is therefore an important issue. To get a complete picture it´s important to also include in the discussion sickness presenteeism, working while ill, and voluntary absence, staying at home without illness. Working conditions have been proven to play a role for the three aspects which is why this study aims to further investigate the connections between them. The method used was secondary processing on interview data collected from two home care teams, one having a low and the other a high sickness absence. The results showed that there were big differences concerning working conditions, where the group with the high sickness absence perceived more stress, less control and less support from colleagues and superiors.

Beräkning av ASME-flänsar enligt EN-standard
In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.
Misslyckandedekonstruktion - en metod att analysera tidigt entreprenöriellt misslyckande
Entrepreneurial failure is probably a subject that is not well understood. This might have to do with the methodological difficulties of screening out failed entrepreneurs. In this thesis a tool is developed for analyzing supposed entrepreneurial failure. In this model entrepreneurs are surrounded by different stake holders. By using the failure deconstruction model to analyze my own entrepreneurial effort I find that it has neither been a successful project nor a disastrous one.
Styrning mot förändring: En fallstudie rörande organisatorisk förändring i offentlig sektor
This paper examines and analyzes effects of the introduction of a new management control system tool within a Swedish public health organization, the Södra Älvsborg hospital, and its possible effect on organizational change. The new management control system tool, known as the SÄS-model, has been widely criticized for being too costly and with too small positive effects to be shown. Our approach has with that as a background been to examine whether the implementation of the SÄS-model and its balanced scorecard has been able to result in effects regarding organizational change. We have through a case study aimed to analyze how a management control system, much alike one that is typically used within foremost private organizations, can promote organizational change. Our results suggest that the implementation of the SÄS-model and the balanced scorecard has given the organization clearer visions and goals.
