In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

The capability to know what knowledge there is and where it resides within an organization is becoming increasingly important in the new knowledge-based economy. This paper takes on a practise-based view of knowledge in order to decide on a course of action for how to successfully implement knowledge management within a knowledge-based company. By considering all knowledge as more or less contextual and socially constructed, knowledge is divided into three dimensions depending on the degree to which it is tacit, namely: information, knowledge and skills. The paper then discusses inhibitors and enablers for transferring knowledge via these three dimensions respectively. The empirical findings are based upon a case study of Faveo. It is shown that Faveo, like most organizations, has til now focused on the collection of codified knowledge, i.e.

Aim: By studying the evolution of the market for package holidays over time we hope to get an understanding of the trends that have characterized the market. By doing so, we can get an idea of where the market is moving towards the future. This knowledge is essential for market participants to establish appropriate strategies that follow market trends.Method: We have used qualitative interviews with people involved in the charter industry.Result & Conclusions: The market is characterized by an increase in Internet orientation, where the travel directory and the physical travel agents are becoming less important. The understanding of climate impacts of travel has increased. More people of the third-generation buy package travels and countries in North Africa and Asia are growing in popularity.We believe the market in the coming years will be characterized by lower prices and lower quality.

Due to human influences on the climate an increase in Earth's mean temperature is today an accepted conception. With a rising temperature discussions have started how the climate in an area will change in the future. Equally interesting and important is it also to study the precipitation in an area. Precipitation is the factor, next to temperature, that affects most how a climate in an area looks like and feels. Since precipitation is connected to evaporation the latter parameter is also of interest to study.

Annual reports are by many considered to be companies primary way to inform their world where the CEO's words are read most carefully by shareholders. The purpose of this paper is to examine the design of the CEO's words in annual reports in light of the financial crisis in 2008. The study seeking explanations for change, similarities and differences in the various texts based on three themes which are results, future and confidence. In this qualitative study five CEO's words are explored by means of a discourse analysis, all from large Swedish industrial companies listed on the Stockholm Stock Exchange. Some of the results shown is that the CEO tends to talk about the company's results in a self-serving manner and CEO speaks more aboutm the results before than after the crisis.

The fact that Sweden has changed from a homogeneous to a heterogeneous culture with multiculturalism as key word requires an intercultural approach in the community and school. The purpose of this study was to examine how teachers of maternal languages experience their teaching in school and what resources they have available from their employer and the municipality. What methods do the teachers in maternal languages use in their teaching at school and what resources do they have to their disposal? How do teachers in maternal languages use the perspective of intercultural education in their teaching and how do the teachers look on their future role in the Swedish school. To achieve this I have chosen the method to make depth interviews with 6 teachers of maternal languages and compare and relate the result to the theories about interculturality and the circle model, to official curricula and to existing literature in this subject.Teachers of maternal languages are very spread out, they work in several schools and sometimes even in different municipalities, during the same week.

Children, who grow up in families, where their parents have decided to take care of a foster child on a commission of the social welfare services, are not often given the possibility to tell about their experience of having foster siblings, in research and other studies. The aim of this study was to give biological children, in these families, a chance to tell their narratives of growing up with foster siblings, creating opportunities for families, who might have plans to take care of foster children in the future. They can get a picture of how it could be for the family´s own children. The biological children got the opportunity to tell their narrative stories including the relationships in their families and how they were looking forward into their own future and family life. The used theory takes part in systemic thinking, looking at the family as an organization and how identities are created in relationships and in communication.

Background:Incoming medical alarm is a common routine for emergency nurses. Working in these situations may represent a major burden on the individual nurse. Purpose: To investigate emergency room nurses' experiences in receiving medical alerts focused on education, safety, security, skills and experience, and andherence to guidelines. The purpose was also to investigate whether there were any differences in action between the emergency room nurses who had worked longer or shorter period than two years with this.Method:The design was quantitative, comparative and descriptive. Surveys were distributed to 30 nurses who worked in the emergency room at a Swedish hospital.

This essay started with a describing of Vision2020 that aims to get incoming tourism doubled and to make global travellers choose Sweden as their destination at the first place. Furthermore, we discuss those 12 priority markets that a Swedish leading communications company in the tourism Visit Sweden puts effort and promotes. Poland was not on the list of the selected countries. With our research we aim to show that the Polish market has potential. Compelling factors point to that Sweden and Poland are neighbour countries with good transport connections and, not least, that the countries have long historical relationships with each other.

In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case.

Purpose: The essay was designed to examine what impact an increased media concentration in the provincial press may have on the society in the future. I also had the intention to create a greater understanding of the concept of media concentration and how the media groups relate to the public interest. Method: The work with this study was conducted by using methods from the qualitative methodological arsenal through interviews with, for the study, relevant informants, but also through a case report on the Stampen Group. The selection of informants had a background and a breadth which secured the credibility in this survey. The starting point was taken in previous research via a deductive approach where I tested how existing theories match reality. Conclusion: After completing this study should be noted that all respondents believe we will see a greater concentration of ownership in the Swedish media market in the future, and that it will reduce diversity. However, there are steps to take which I believe can work well in theory but perhaps not always in practice.

In Stockholm there are currently five women, out of a total of 102 employees, working in public sports arenas. In sports arenas men are numerically superior amongst the workers as well as the visitors. These arenas are in many ways male dominated, masculinized environments. In this essay I investigate the reasons behind the uneven distribution, in terms of gender, among sports arena workers. I do this by interviewing seven female sports arena workers (the five current and two former), and by observing their workplaces.

I följande uppsats undersöks attityder hos kunderna på Stockholms cafémarknad i syfte att undersöka möjligheterna för McCafé-konceptet att lanseras på stadens marknad. McCafés största konkurrensfördel identifieras som pris genom att studera hur konceptet utvecklats och ser ut i andra länder. För att få en nyanserad bild av kundperspektivet genomförs en enkätundersökning i centrala Stockholm med 222 svarande. Enkätundersökningens första del bygger på the Theory of Reasoned Action där konsumentens påverkan av olika attribut betraktas genom att låta denne utvärdera situationen på marknaden och sedan värdera vikten av samma attribut. Dessutom tittar teorin på förändringspotentialen för de undersökta attributen.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

The purpose with our study is to investigate in which way a public field of action has succeeded to make the economic management more effective and also find out which factors/activities that have contributed to get the result of the budget in balance. We also want to find out in which degree the balanced scorecard (BSC) has contributed to the positive result of the budget. Method: We had started out from the qualitative method theory which is based on the hermeneutic theory, because we will interpret and understand. With this starting point we have chosen to use a case study with semi-standardised interviews supplemented with information from different documents, and to get the theoretic connection we have studied literature in the subject field. The analyse and even the theoretic connection have then started from, for this study, a special analyse model.
