Studie av vÀrmeflöden i befintligt bostadsbestÄnd : UtvÀrdering av energieffektiva besparingsÄtgÀrder

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

Microstrip Solutions for Innovative Microwave Feed Systems

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.

Motivation in Knowledge Intensive Firms - More art than science

Workers are more demanding than ever and stay a shorter amount of time within the same organization. For this reason we wanted to look further into how organizations work with motivation in order to create success in Knowledge Intensive Firms. The complexity of knowledge workers formed the base for our interest within the subject. The purpose of our thesis is to reflect upon what is written about the motivational effects of recruitment and reward strategies in Knowledge Intensive Firms. Further our essay is based on an abductive advocacy.

Konfliktfyllt? : Sverigedemokraterna, demokrati och skolans va?rdegrund

The aim of this thesis is to illustrate the content of the democratic values tolerance, personal development and political equality, in relation to the Swedish school?s systems fundamental values, and from there problematize the schools approach towards the Sweden Democrats. By using a qualitative text analysis upon the party program of Sweden Democrats, we have been able to fulfill the aim of the thesis. We have motivated and defined our chosen democracy values from the schools fundamental values and from democracy theory. With the use of an analyze schedule we have been able to go through with the interpretation and analyze of the party program of the Sweden Democrats.

SAB-systemet och Àmnet religion en studie av ett klassifikationssystems förmÄga att klassificera en vetenskaplig discipline.

Classification systems express an idea of the world as it was when the systems was made. If the classification system is not revised there is a possibility that the system will become antique and hard to apply to different subjects. The purpose of this study is to see if the SAB-system is a classification system which shows a reflection of the subject Religion that is equivalent with that of Swedish universities. The ideas which are behind the classification of the subject religion in the SAB-system have been analysed, as well as the structuring of the scientific discipline Religion at the universities. The result will show if the SAB-system can classify the subject religion in a satisfying way at university libraries.

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

MilitÀrtekniskt perspektiv pÄ AUV

Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.

Axle Link - en kortslutningsskyddad sÀker DC-överföring

Denna examensrapport redogör för hur man kan fÄ en kortslutningsskyddadoch sÀker inkoppling av en DC-lÀnk mellan tvÄ skiljda elektriska system.Rapporten bygger pÄ hur en lastbil ska kunna fÄ en större sÀkerhet för attbibehÄlla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem bestÄr idag av tvÄ skiljda elektriska system med ett 24volts strömförsörjande batteri vardera.
