A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

The BSC is a widely used management tool that is turning the vision and strategy into operational goals. However, after analyzing the criticism received by the BSC, it seems as if its internal focus, rigidity, static-ism and mechanical mindset limits the company?s ability to create a strategy that takes important external factors into account. As we see it, the BSC?s limitations can create a risk for strategic inertia.

This study is based on the development of a new software, which is used as a recommendationtool for selecting the best product. As part of the software development has an external partnerbeen asked to assist. The report will process the expectations that different people have on anew project but also how information is communicated to an external partner.The results from this study show that a software's function is closely linked to its usability.Therefore shall usability been taken into account when a new resource is created. The study alsoshows the importance of being able to share information, on how the program will beconstituted, to someone outside the organization..

The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.

The goal of this project was to implement and compare Invere Discrete Cosine Transform using three methods i.e. by bit parallel, digit serial and bit serial. This application describes a one dimensional Discrete Cosine Transform by bit prallel method and has been implemented by 0.35 ìm technology. When implementing a design, there are several considerations like word length etc. were taken into account.

Aim - To investigate the prevalence of allergies among students at The Swedish School of Sport and Health Sciences (GIH) in Stockholm and relate it to factors that previous research in this area found to influence the risk of developing allergic diseases.- Can Hygiene Hypothesis or more specifically the relationships of family structure, socioeconomic status and the degree of overcrowding explain the existence of allergies among students at GIH?- Can the prevalence of allergies among students at GIH be explained by any of the known relationship for the prevalence of allergic diseases this study has taken into account?Method - Quantitative survey of students at GIH in the fall of 2013.Results - 214 students from The Swedish School of Sport and Health Science participated in the study, with representation from the first - and last - year students of all educational programs. More than twice the proportion of those diagnosed respondents said that their mother smoked during pregnancy or while they were breast-fed compared with the same group of respondents with no allergic diagnosis. The correlation is not statistically significant (p -value: 0.054). The majority of respondents with an allergic diagnosis indicated that their home mopped once a week or more for most of their childhood, while the majority of respondents with no allergic diagnosis stated that their home mopped less often.

Empress Livia ? Murderer or wrongfully accused?An overview of the ancient sources on the empress Livia and what that suggests that shemurdered her husband Emperor Augustus and his adoptive children to make way for herown son Tiberius as the emperor of Rome.This work will analyze the ancient roman sources by the great historians from that time;Tacitus, Suetonius and Cassius Dio, and their works discussing the murder conspiracy of theempress of Rome; Livia.Here I examine what these ancient sources tell about the possible involvement of Livia, on thedeath of Augustus himself and his adoptive sons. Each author to these ancient sources will beexamined and contextualized according to their contemporary time, but also their political andideological views of women in high position and Ceasarism itself. Their characteristics andstyles of their written account will also be examined.The following issues will be dealt with in this work:? What does the ancient sources of; Tacitus, Suetonius and Cassius Dio say about theconspiracy theory in which empress Livia is central.? What is known about the authors of these ancient sources and to what extant mighttheir political and ideological view affect their written account?? Can the allegations directed at Livia be the result of the fact that she was a highlyinfluential woman at her time, something which the ancient authors by romanstandards saw as unfit for a woman, and therefore is mistreated in the written sources?? If so, were all women with power under the same time and circumstances criticized inthe same way in which Livia is portrayed?? Are there any other aspects that have not been treated equally in the past by authorsand researchers, in which new questionable guidelines can be made?As is very important to point out, this work and essentially all others alike will not evenassume to solve the final question if empress Livias was guilty or not of murdering herhusband, Emperor Augustus and/or his adoptive sons.

This paper studies the philosopher Ludwig Wittgenstein during his years (1920?26) as an elementary school teacher in remote Niederösterreich, Austria. The paper gives a survey of his life, and also a brief account of three of his main works: Tractatus Logico-Philosophicus, Philosophical Investigations and Remarks on the Foundations of Mathematics. Attention is given to his alphabetical word list, Wörterbuch für Volksschulen, published for educational use in elementary schools. The study is focused on Wittgenstein?s educational practise, and establishes a connection between his experience as a teacher and his late philosophy..

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.

The purpose of this thesis is to investigate the fatigue life of two components in different hydraulic quick couplings. The crack which initiates the fatigue failure usually occurs in the bottom of one of the threads. Thus, the threads in the coupling are carefully investigated. A few different approaches for determining the fatigue life are studied for each component. CAD (Computer Aided Design) models for both components are created and analyzed with FEM (Finite Element Method).

The aim of our study was to increase understanding of older people?s views on social media?s and identity by asking the question: How do seniors perceive identity on Facebook? Based on a qualitative approach with written interviews conducted by e-mail, we contacted respondents who had and used a Facebook account. In our study we used categories, such as seniors, identity, Facebook and networking to be able to answer our research question. The result of this study is shown as a description of nine respondent?s testimony regarding identity on Facebook.

When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.

The starting point of this study is that the news media in general strongly influence which topics determine the public agenda by their choice of what is considered newsworthy. The study is based on articles from two major Swedish daily newspapers, Svenska Dagbladet and Dagens Nyheter. The aim of our thesis is to establish how the environmental public debate as portrayed in the newspaper corresponds to the environmental discussion within the scientific (subject matter expert) field, that is taught by the academic institutions, or if the two materially differ. The environmental communication discourse at the academic institutions advocates ?episodic? formation as the driving force behind transformation of attitudes and behavioral preconceptions. This episodic formation is aimed at incentivizing change by creating intimacy to the incident by linking cause and consequence to the individual citizen instead of to society as a whole.

This report addresses the growing need to adapt the medical healthcare to the new possibilities that can be accomplished by incorporating a web aspect to the personal treatment plans of patients. It describes what implementations that need to be considered in order to successfully convert to a partially web-based treatment.The report also reflects the potential economical gain that can be made by keeping the communication between the patient and the doctor frequent. It also takes into account the personal gain to the patient by increased feedback and easier ways to communicate with their attending physician and thereby increasing the quality of their healthcare and service.The construction of a prototype of the system required is also included in the report as a description of construction and functionality of the prototype along with results and estimated outcome..
