Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

AbstractDigital media in general and social media in particular are becoming more and more important to businesses across the globe. It is an effective way to reach out to consumers and establish a good relationship with existing customers. Most companies today use digital media in order to market themselves and to establish good public relations. A lot of those companies have also realized the enormous marketing capabilities that social media provides. However, in spite of the plethora of possibilities that comes with social media it can also, in some cases, hinder the companies ? success.

In today's social work there is an ambition to work evidence-based in order to improve quality and competency in business. This study is made in a disability administration which has introduced a common approach towards users for all employees. The approach is called low arousal approach. The purpose of the study is to investigate how a method takes hold and implements within an organization. The empirical data is analyzed by theories of professionalization, idea dissemination and translation.

The process of value creation is rapidly shifting from a product- and firm-centric view to personalized consumer experience today. Informed, networked, empowered and active consumers are increasingly co-creating value with the firm. The interaction between the firm and the consumer as well as the experience factor plays an increasingly important role in determining the success of a company?s offering. In this study, a special type of co-creating experience is investigated - ?omstartspex? - where the audience is interacting with actors during the play.

This thesis investigates the dynamics of the relationship between a leader and the followers within a chosen organization. The research on leadership has generally been focused on the leader, and consequently treating the followers like passive subordinates. We pursue a more multidimensional view of the subject, meaning that leadership descends from an interaction between leaders and followers, which makes it relevant to study the dynamics of the relationship from both perspectives. We chose to do a qualitative case study on a middle- and preschool which has won a price for being an ideal place to work at. This price peaked our interest to investigate why the relationships are highly functional in this particular organization.

The aim of the study is to examine factors influencing students? feelings of pleasure or pain associated with school mathematics. Own experience of students? frustration about mathematics and concern about students not reaching desired goals is the driving force in this study. It contributes with knowledge from the students' perspective.

The international requirement of Swedish healthcare today is high and due to a good reputation and a long history of reliable methods through extended experience. For those Swedish companies within this business, the process of internationalization is often a attractive option.This study aims to describe, analyze and translate how minor Swedish companies within the care keeping section establish their business on the international market.The study is based upon a qualitative approach and is an empirical study carried out through semi-structured interviews.The result presented in the study shows that internationalization of companies within this business does often require a lot of time and money, is based upon establishments through networks and were learning-by-doing often is used as a strategic approach for the companies penetrating a new market.The study also accounts for major entry barriers, which declares for being to some part of political nature, but mostly of cultural nature.Differences in language and culture are shown in the study to be a major entry barrier and host-countries different cultural levels are very conclusive for the success of internationalization. .

?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.

På senare tid har konkurrensen om kunder ökat bland företag vilket gör att behovet av konkurrentanalyser har ökat. Trähusbranschen är en bransch där behovet av konkurrentanalys är extra stort eftersom det finns många företag som konkurrerar på en begränsad och konjunkturkänslig marknad. Konkurrensen inom branschen blir dessutom hårdare eftersom kunderna oftast är privatpersoner med stora krav på produkten men med en begränsad ekonomi. I denna rapport har konkurrensförhållandena inom trähusbranschen undersökts på en geografiskt begränsad marknad. Undersökningen inriktades på att hitta de absolut viktigaste faktorerna som gör en husleverantör framgångsrik.

I chose to study how the Swedish Air force carries out their work with setting goals for their work to improve flight safety and compare this with how the Swedish nuclear power plant Forsmark performs their work with improving nuclear safety. The study showed that both organisations have a lot to improve on in their ways of how to work. Especially when it comes to engaging the employees in the process, both in letting the employees be a part of coming up with areas to work on and in letting the employees evaluate which progress that has been made. It also showed that both organisations need to improve their methods for evaluating the work that has been done. This is especially important for the Air Force which evaluates on many levels and locations and did not have a set standard for how to conduct the evaluation.

In our thesis we investigate how public libraries are working with external marketing via social media. The study aims to found out what the reasons are and how public libraries are using social media to market themselves. Furthermore, how they evaluate the success of these marketing efforts. We limit ourselves to public libraries and its staff. The theory that we have chosen to use to analyze our data is the marketing mix of the 4 P'S (product, place, price and promotion), but we have replaced the ?price? with ?staff? because ?staff? is more relevant for library management.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

The ever-changing modern health care environment places high demands on leadership skills. The purpose of this study was to describe the causes that effect leadership within the health care services carried out in a municipality. Data was collected by interviewing four health care managers, three registered nurses, eight enrolled nurses and one auxiliary nurse. A qualitative approach based on a content analysis method was conducted in the analysis of the interviews. Latent content deals with relationship aspects and interpretation of deeper underlying meaning of text.
