The purpose of this thesis was to increase the understanding and discuss safety aspects in two stairwells on Nyforsgatan in Eskilstuna, where the buildings were built during the years 1965-1975. I have presented a proposal for improvement through lighting. I have through different methods, such as surveys, interviews, literature studies and observations, come to a conclusion: that there are opportunities for improvement through better lighting that allows orientation in space and creates a nice atmosphere which will remove the feeling of not being safe, e.g. dark corners and shadows. It has been an exciting process to gather enough of facts to rely on and to develop the lighting design for the environments.

Purpose: The purpose of this study is to examine whether hedge funds generate higher risk-adjusted returns than traditional managed funds in Sweden.Methodology: This study was based on quantitative data about the funds historical returns. The funds historical returns were taken from the database Morningstar and the risk-free rate from the Swedish central bank. Random samples of 36 funds have been divided into three portfolios in the form of a hedge fund portfolio, stock portfolio and mix fund portfolio.Result & Conclusion: The study concluded that the stock portfolio has shown the highest average yield for the study period where all portfolios below market index. Hedge fund portfolio has achieved the highest risk-adjusted return calculated by the portfolios Sharpe Ratio. Of all hedge strategies, arbitrage had the highest average return and risk-adjusted returns..

Tile covered bathrooms require a wellexecuted waterproofing in order toprotect the underlying construction frommoisture. Länsforsakringar Uppsala paysannually out millions in insurance fordamages related to poor waterproofedbathrooms. In recent years, SP (SwedishNational Testing and Research Institute)investigated and researchedwaterproofing products, resulting ingreater shortcomings of product defectsthan expected.This report raises the problemsconcerning waterproofing and discusseswhy they occur. By studying productinstructions and insurance cases anddamage reports provided byLänsforsakringar, the most commonproblems concerning bathroomwaterproofing where concluded. Animportant part of the report was tofind out the actual cause to whywaterproofing damages occur.The results of the survey indicate thata common cause of water damage usuallyis related to poor productinstallations.

pelago. There is an old inn that is located on the island that has become a very popular attraction in the last couple of years. The inn has both a well-known restaurant as well as conference facilities that are used by tourists as well as the people of Stockholm over the summer months. The inn was built 1908 and has since remained in the same condition.make islands in the archipelago more environmentally friendly and promote sustainability. One of their project islands is Grinda.

The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Climate change is a global and slow process that affects humans all over the world. Climate adaption within agriculture is important to reduce the risks that agricultures are exposed to because of climate change.  Through climate adaption you can improve the positive effects and take advantage of them optimally. How the climate change affects agricultures varies depending on regions and societies. The purposes of the study are to examine how different actors experience the impacts of climate change on the agriculture in Värmland.

During the past year it has been made possible to buy back a company?s outstanding stock. This is done in order to change the capital structure towards a situation with less equity. A change in capital structure means a change in the cost of capital for a company and by that a change in the value for the stockholder. This Master Thesis studies the relation between capital structure and business risk.

This paper deals with hill-forts located on and directly south of Selaön, in the center of Mälardalen, Södermanland, dated to the late roman period and the migration period. Of special interest is differences and similarities between the forts when it comes to their morphology and the hills where they were built. Furthermore, their landscape has been examined and I have tried to put the hill-forts in relation to any iron age settlements..

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Social media is by many believed to be the core of a new type of Public Relations. This new PR is called PR 2.0. Most larger companies today are to be find using dif- ferent types of social media to interact with their publics. Each year companies invest more money in this type of digital public relations. Social media is a relatively new online phenomenon and still used at a very early stage.

This essay, Jacobsberg ? a Landscape Garden and a Cemetery is a documentation and a historical analyze where I?ve been focusing on the development of the landscape garden in Sweden in relation to a garden called Jacobsberg. The garden was built close to Visby on Gotland in the early 1800s by the assessor Jacob Dubbe, but has since been almost forgotten. My survey aims to depict the circumstances surrounding the creation of Jacobsberg. In what purpose was it built? I?ve also been examine the historical context of the garden?s origins with the intention to define and confirm its architectural style.The essay comprises two major parts, where the first part deals with the history behind Jacob Dubbe and Jacobsberg, and contains an illustration of the assessor?s life and of the garden?s original structure and shape.

Sow shoulder lesions are a common form of decubital ulcers in sows. The wounds are often bilateral and affect both loose housed and restrained sows. In most cases shoulder lesions develop after farrowing and heal after weaning. Sows that once have had decubital ulcera are however more proned to develop new wounds after the next farrowing. The problem is multifactorial and a number of risk factors have been described, including body condition, body size, parity, time spent lying down, flooring, moisture, breed, body temperature and some herd factors. The aim of this study was to investigate whether the height of the tuber spina scapulae is a risk factor for the development of decubital ulcers.

In this essay a proposal of city renewal is made for the new train station area built on highly productive agricultural land in Landskrona. The proposal is based on how the situation for the agricultural land in terms of exploitation looks like today and also on theories of urban governance to find out why the area turned out the way it did..

The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.
