This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Fashion creates reactions. It is a type of art form that constantly needs to be updated. This is the thrilling part about fashion, but it is also the part that can create unintentional reactions.In this essay I will examine two garments that have achieved a great amount of media coverage, both in Sweden and abroad. One of them is a jumpsuit from H&M that was criticized because of the resemblance to the uniform worn by the Peshmerga-soldiers in Kurdistan. The other garment is a children?s sweater launched by Zara.

Research on the power of customer involvement, and in particular recommendation is very resourceful. Many studies have mapped the reasons for why customers are willing to recommend, however they often ignore potential differences among brands and how that may affect these reasons. This study is built on a quantitative survey investigating how consumers interact with brands, depending on category affiliation. The categories used were Bhat and Reddy's symbolic and functional, consisting of three brands respectively where each brand represented a different product type.The evolvement of social media has also transformed the platform of recommendation from physical to virtual and changed the way people connect. Thus, taking the investigation further, potential differences between symbolic and functional brands was tested in different social media platforms.

News value is an essential part of which event media chooses to report about. Political events consider to bee news with potentional large value. Media has an enormous power and possibility to create news and construct there own reality and where the readers is given a false expression of what really happened. Today the media must show profit and that indirect affects how the media choose to describe political events. In the Kenya case is it therefore possible to draw the conclusion that the two news paper has different construction of the political event in Kenya.

Common wisdom dictates that because payment of dividends decreases funds available for investment, a high payout ratio is to be associated with low earnings growth. This notion has been challenged in recent years by empirical research that has found a positive relationship between payout ratio and future earnings growth, both on the aggregated market level and the company level in different countries. This study investigated the aforementioned relationship on the Swedish market by statistically analyzing future earnings growth as a function of payout ratio on a large sample of publicly listed companies over the period 1980 to 2011. The results are in line with those found in previous research and indicate that companies with high dividend payout ratio tend to experience strong future earnings growth. The results are robust to the presence of mean reversion, the use of an alternative accounting measure of earnings, non-symmetrical earnings growth cycles and alternative practices for dealing with outliers..

When I got the opportunity to write this examination did I want to write about something that I both was interest in and also can use in the future. I think it?s going to be difficult to carry on the milk production with only 28 cows. I wanted to investigate the possibility to increase the herd of cows. I also wanted to compare this cost with a new cow house the cows where milked with a robot.

The aim of this Master's thesis is to explore how the localisation and the design affect the conditions for a school-media centre. A school-media centre is in this study a place where the students seek, find and evaluate information, discuss and exchange ideas. An active place for generating knowledge. The method applied in this study is "Space Syntax Analysis", a quantitative method with visual representation of the results. In the theoretical framework, space is the voids between walls, doors and ceiling, between furniture and bookshelves.

The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.

For the last ten years Internet has become more popular and is now used by most Swedes every day.  Internet has made it possible for many people to access a great deal of information about news all day long. Internet has also made it possible for people to create their own news and comment on happenings as they are taking place. One way to do this is to start your own blog, which is a kind of diary where you can publish your own thoughts about politics and news.In Sweden the media is often referred to as the third governmental power since the media is examining the government and people in power positions and bringing the people as consumers of news closer to the government. There is a theory called agenda setting that says that the media is an actor that shapes the political issues discussed by the people and politicians.In this essay I have used the agenda setting theory and linked it together with the Medias references to blogs in their news. This I have done to see if the media might be influenced by blogs.

This paper is about our collective fascination for the social medium Instagram, and our lively discussions about why certain images may be more so-called "Liked" than others and why some individuals becomes more successfull on Instagram than others. Thanks to our own daily use of Instagram, the idea was born to study and look at how some individuals build their brand through this social medium. With social media new ways to construct and communicate images have appeared. Artists, celebrities and companies use media as a channel for communication and marketing. In our study, we focus on the use of Instagram for marketing purposes by Rachel Brathen, one of the worlds most well-known yogainstructors.

My choice fell on this method because I believe it to be the most suitable for obtaining the data needed.

The weather has been extremely rainy the last summers in Sweden. Because of the rain, a lot of harvested straw has been lost since it was too wet to store. When the pig producers couldn?t get enough straw to use as bedding, an alternative was requested. Silage is a realistic alternative to straw but since silage often contains clover, it may not be suitable to use in pig production since clover is rich in phytoestrogens.

Problem: Companies are becoming more active in social media. They usechannels such as Facebook, to communicate and interact with theirenvironment. In connection with this, companies must also be prepared todeal with crises in social media. Previous research shows no clear guidelineson how companies can work in social media to prevent crises.Purpose: The purpose of this qualitative study is to examine how companiesin the communications industry can work with Facebook to prevent crises.We hope that our study can provide new perspectives and guidance on howcompanies can work with emergency communication for prevention.Methodology: We used a qualitative research to arrive at our results. Thismeant we got an insight into the complex world that companies are workingin.

The main purpose of this essay is to investigate the legal position for employers concerning protection against what employees can express about one?s employer in social media.It may regard dissatisfaction concerning employment, tort or so-called whistleblowing. The spread through social media may be comprehensive and thus cause more damage to the employer.Employees within the public sector as well as in the private are protected by the liberty of speech, which is constitutional, even the protection of sources or the right to criticize can offer some protection. This gives the employees the possibility to widely express themselves in private social media as long as it can?t be classified as a violation, which per se is very rare.However, certain differences between the both sectors will be pointed out.There are still no constitutional rights regarding social media, but a grey area has emerged concerning the legal position.

This study investigates a farm in Dalarna which includes 16 ha of farmland and 1, 7 ha of pasture. The purpose is to find out if it is possible to start an animal production in Dalarna. The study is set only to compare spring lamb production with nurse cow production. There are two buildings on the farm that can be used for this purpose. One is an old cowshed, and the other is an unused silo for silage with a roof on top. Both of the buildings are compared to every alternative in the calculations.
