AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

After parturition the energy demand for milk production is greater then the energy provided from the diet. The cow mobilises therefore body tissues to compensate for the energy loss. Live weight and body condition scores decreases as a consequence of the mobilisation. The aim of this study was to analyse the relationship between body condition score, live weight and subcutaneous fat depth measured by ultrasound and the changes during the lactation. Possible differences between Swedish Holstein (SLB) and Swedish Red and White Cattle (SRB) were also investigated.

Uppsala like many other Swedish cities is affected by heavy housing shortage, in terms of too few existing flats and residents within the city limits. Every semester thousands of new students are facing the same problems of finding themselves adequate accommodation. The waiting lists for flats and student-dorms are getting longer for each year, and the situation is just getting worse. Simultaneously, Uppsala?s ambition is to increase its population and expand as a Swedish metropolitan, according to the Swedish governmental environment goals. This paper investigates and analyses the possibilities of expanding a city?s population by building high-rise buildings.

The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures.The suggested system gives opportunities to introduce biofuels in new areas.Main components in the suggested system is a heat radiating combustion chamber intended for pulverized wood, combined with regenerators to extract heat from flue gases and simultaneously preheating the combustion air.The thesis contains a description of the suggested system, theoretical considerations, calculations regarding the combustion, and includes results from tests performed.The results from calculations and tests performed concludes that the system is workable and possible to apply..

In advertising, the target has traditionally been aimed towards the product?s advantages.Today the trend is that the advertisers want to create a restless and unsatisfied consumer. Theconsumer on her part is not trying to achieve a goal with her consumption, but experiences theconsumption itself as a goal. Because of this the consumer demands a fast and variedselection.In order to sell their products the companies must create a non-existent need amongst theconsumers. Therefore it is very common in advertising today to use emotions instead ofinformation to attract the customers.

Purpose: The purpose of this study is to do a brand survey of Metro in Karlstad. The study will originate from the terms ?brand identity? and ?brand associations?, where the brand identity is the organization?s desired view of the brand, and the brand associations define the associations held by the consumers.Issues: What is Metro?s brand identity? What are the brand associsations of Metro in Karlstad? How well do the brand identity and the brand associations correspond?Theoretical framework: The study is done from the perspective of media and communication studies, where the theoretical terms are defined from literature regarding brands.Method: The study is carried out using a qualitative document analysis, interviews, and a quantitative survey. The document analysis was made on Metro?s own documents regarding values and target audience.

There is an old saying, that after Epaminondas nothing was ever the same again. In this thesis I will focus on three questions: "Epaminondas the man." Who was he? "Epaminondas the general." How did he change the technique of warfare that made it possible to beat the Spartans? "Epaminondas, founder of cities and wall-builder." How did he build the walls around the cities he initiated, that made them resist enemy attacks for many years to come?While seeking the answers to yhese questions I will make a contextual analysis to get the historical background to all the phenomina involved..

Purpose: The aim of this thesis is to create a greater understanding of organizational identification and the factors influencing this process. The understanding will be obtained by identifying what individuals identify them selves with and why this identification occurs.Method: The thesis is a case study with an abductive research approach with a focus on organizational identification. Data has been collected with a qualitative focus in interviews and images.Conclusion: The employees at Plain Capital primarily identify themselves with their profession, the company and their co-workers. The reasons why they identify are mostly because of the feeling of pride and participation. We have discovered a link between a strong group identity and a high organizational identification.

This case study examines how individuals involved in the Swedish peace movement have navigated their peace activism due to the intensified security debate which followed Russia?s full-scale invasion of Ukraine in February 2022. By conducting semi-structured interviews with peace activists involved in the Swedish peace organization Svenska freds- och Skiljedomsf?reningen, the study aims to provide insight into how peace activists, and the peace movement as a whole, can be affected when the security debate intensifies. By applying a theoretical framework consisting of Political Process Theory (PPT) and Discursive Opportunity Structure (DOS), as well as previous studies and literature on social movement organizations and peace movements, the study?s objective is also to apply context to the observations made by the peace activists in the study.

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

This thesis contains an empirical study of exhaustivity in the Swedish National Union Catalogue LIBRIS. The purpose of the study is to examine if fewer numbers of indexing terms in general lead to lower exhaustivity. The study contains two parts, the first part examine the mean of indexing terms per monography in the selection, the second examines the grade of exhaustivity within three groups with a low, moderate or high number of indexing terms. The 55 randomly selected titles were graded on a scale that was created from the indexing theories of Wilfrid F. Lancaster.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.
