In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

Technological advancements in information and communication technologies (ICT) have resulted ina need to use ICT in schools. Sweden has actively promoted ICT in schools since the early 1980's.In Japan, 1994 saw the government's first step towards active promotion of ICT in education. In thisstudy, we have compared the strategies used to promote the use of ICT in elementary and secondaryschools in Sweden and Japan. Our findings suggest that a similar 3-step approach was used in bothcountries: 1, infrastructure; 2, effective use of ICT; 3, implementation of ICT. A significantdifference was found in the way the two countries planned their strategies.

Abstract I have made a Website called ?Art school? for Liljevalchs art Gallery, Culture administration in Stockholm and Culture school in Stockholm. It is with scholarship from these that this Website has been possible. The work whit the ?Art school? started in the autumn of 2005 and ended in May 2006 on distance from Stockholm towards Blekinge technology school in Karlshamn. The Webb place is for the general public, but most for people who have interest in art and for those how want to learn more painting in different mediums. This Websites I name: oil, watercolour, acrylic, coal, gouache, and graphite. On each one of these mediums you?ll get to know about their history, what technique they have, what sort of material you need, practise and tip.

In this study I will analyze how men who buy sex interact with one another on two different Internet communities: ?Sekreterarakademin? and ?Flashback?. This analysis is carried out in an attempt to challenge the conventional image of the man who pays for sex.The aim is to examine the role of Internet forums for men who buy sexual services related to cross-border, both in terms of standard borders, gender boundaries, boundaries of sexuality and masculinity. I will also attempt to investigate what opportunities that are available to overrun different borders and how these opportunities affect the conditions of the various players. I will evaluate theories such as homosocialtet, hegemonic masculinity and normalization used by KAST (Köpare Av Sexuella Tjänster, the Swedish public support for clients of sexual services) and which are partially consolidated in studies published by KAST concerning issues related to internet based prostitution..

In this work an assessment of the compressed air system in the facilities of Vattenfall Heat Uppsala has been conducted. The facilities constitutes, among others, a combined heat and power plant, and two waste incineration plants. The compressed air is supplied primarily by seven rotary screw compressors and yearly electric energy consumption in these has been determined. Furthermore, the usage of compressed air has been mapped in order to find processes with energy savings potential. Several suggestions how to reduce the usage of compressed air have been presented, resulting in decreased need of electric energy and reduced CO2-emissions.The results show that total need of electric energy in the compressors, during a standard production year, amounts to 5.83 GWh.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

Syfte och frågeställningarSyftet med studien var att undersöka för elitorienterare resultaten vid och korrelationen mellan ett så kallat 5 minuters pyramidtest (5MPT) och ett maximalt test för bestämning av maximalt syreupptag (VO2max) på rullband. Frågorna vi ställde oss var: Vilken korrelation föreligger mellan 5MPT och ett bestämt VO2max på rullband hos elitorienterare? Hur ser en jämförelse ut mellan uppmätt samt beräknat VO2max? Vilken är reliabiliteten för 5MPT? Hur ser ekvationen ut för att beskriva sambandet mellan dessa två olika maxtester?MetodI valideringsstudien deltog 16 elitorienterare (6 kvinnor och 10 män) i åldrarna 17 till 37 år. De två testerna som genomfördes var 5MPT och bestämning av VO2max på rullband. 5MPT är ett skytteltest som är fem minuter långt, där testpersonen (tp) tar sig fram och tillbaka mellan två stolpar (sträcka 5.5 m) där en vertikal trappa (formad likt en pyramid) passeras under varje vända.

The focus of this work is to study whether public libraries should offer their patrons unlimited access to the Internet, or restrict which sites they can visit. The most common tool used to limit Internet access is filtering software. The author has administered four interviews with public librarians working in libraries in Southern Sweden. All four librarians had different opinions about restricting Internet access. The most important question asked was if they had chosen to use filtering, and the reasons for their decision.

Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.

The market-leading wage and PA-.system for the Swedish public sector Palasso is developed in Karlstad. In order to achieve the highest quality of code , the developing team behind Palasso has been conducting extensive testing. Testing is done to ensure that the software does what it should do. However, the testing has been done at a high level. In order to continue to evolve, the group that develops Palasso has started to look at the new development methods that have become popular in the computer industry in recent years.

The purpose of this paper is to standardize and simplify the design work on a few specific types of storage brackets for balconies. The company Balco AB had the wish to simplify the design work in the preparation of attachments to their balcony structures. This would be done by a calculation matrix that could be produced which then in turn could be used for each new project by the company. The design work behind the development of these fittings at each new project is costly both in terms of time devoted by each calculation but also the cost of the time. The purpose of this report is that in a systematic manner, a calculation matrix can be created that then the company instead may follow from each new project.In carrying out the project used HILTI calculation program, which was provided by the company HILTI.
