Implementation of a Data Handling System for a Scientific Magnetometer on a CubeSat
Since their invention in 1999, CubeSats have become a widespread standard for small picosatellite missions. CubeSats allow for quick development of satellite payloads and launch in space without the high costs of a normal satellite. Emphasis during the CubeSat design process is placed on use of commercialoff- the-shelf (COTS) components and reuse of previously-designed units.This report describes the interfacing of a scientific magnetometer, the Small Magnetometer in Low-Mass Experiment (SMILE) to such a CubeSat mission, the Space Weather using Ion spectrometers and Magnetometers (SWIM). Design of a complete platform for use in multiple such missions is presented here.Modularity is one of the key aspects followed in the course of the work. A new board containing the analog pick-up and compensation circuitry for SMILE has been designed to fit inside a CubeSat frame.
HAVS ombord - en studie av hand- och armvibrationssyndrom och dess förebyggande åtgärder
On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.
Södertörns Högskola - en skola för B laget? : En diskursteoretisk analys
Södertörn University was built in the suburb of Stockholm to bring hope for students that aren?t used to study. Ever since the university was built there has been a debate on internet message boards such as Flashback and a discourse has developed in the recent five years. The public discourse has had a negative influence on how the university is perceived by the public. The purpose of this study is to analyze how this discourse has developed the image of the university and how it has evolved.
Styrelsens unika kompetensbehov : En studie av kompetensförändringen i styrelsen
Background: The board of directors is a key player in corporate governance. Their role is to ensure that the corporations are run with the interest of the shareholders as the main focus. In the beginning of the 21st century, a survey was made about the confidence of the Swedish business community and in which criticism was directed to the board of directors. The boards were deemed inadequate in their function and were often solely composed by members with similar experiences and competence, therefore lacking in diversity. In order to improve the competence and work of the board of directors, the Swedish code of corporate governance was introduced and its recommendations comprehend the boards? size and composition.
Vad är meningen med värdegrunden? : Om svårigheten i att förena teori med praktik i värdegrundsarbetet i skolan
The topic of this essay is core value issues, how they are mediated in school and how they are practiced. I am investigating a problem concerning the existential worth of the core values-content for children, or in other words, the difficulty of reconciling the theory of the core values and their practice. This problem is portrayed by two stories. The aim of this work is to investigate how to combine the core values theory with its practice, in other words, make it meaningful. In my essay, I turn to recent research in the field to provide a background to my issue, and hereby further point to my problem.
Valberedningen enligt Svensk Kod för Bolagsstyrning: En studie ur ett institutionellt perspektiv
With the introduction of the Swedish Code for Corporate Governance in December 2004, most companies listed on the major Swedish stock exchanges were required to have a nomination committee responsible for, among other things, evaluating the incumbent board and nominating new candidates. This master thesis aims at analyzing the effects of these nomination committees on institutional investors in their corporate governance, through a qualitative study of 13 interviews. We have found that institutional investors have become more active through their participation in nomination committees and that they have gained more influence over the companies in which they own shares. We believe that in reality nomination committees have more influence over the selection of the board than was intended when the Swedish Code was written..
Hästinventering i Degerfors kommun
Animal welfare in Sweden has gone through major changes during the later years. In 2004, Swedish Animal Welfare Agency took over the central responsibility for the animal welfare from the Swedish Board of Agriculture, and in 2007 the board again became the central authority for animal welfare in Sweden.Even the practical supervision has changed, from the 1 of January 2009 the supervision is to be performed by the county administrative boards, instead of by the individual municipalities.
Since 2006 every horse in the European Union has to have an identification card, in Sweden called a ?horse passport? which describes the color and markings of the horse as well as any veterinary treatments.The ELOF-project, a collaborative project between the Swedish Board of Agriculture and the county administrative boards, intends to make the animal welfare supervision effective, standardised, fair and risk-based. Because of the takeover of the supervision and of the ELOF-project the Örebro County Administrative Board has began to make an inventory of the number of horses and horsefarms in the county. Another Ethology and Animal Welfare-student and I did, in collaboration with the county administrative board created a checklist that in connection with the inventory will lead to a risk-based animal welfare supervision.
Olika generationers kunskapslegitimering. En kvalitativ studie om kunskapsöverföring i ett IT-företag
Companies? ability to differentiate themselves from their competitors becomes increasingly difficult when standardized technical solutions are used, which means that the employees become the most important resource. Many workplaces consist of a mix of employees with different backgrounds and of different ages, which highlight the generational perspective. Previous research has long focused on different generational drivers and of motivation at work, but there has been few studies in which the transfer of knowledge between generations have been examined. With that as a background, a qualitative interview study was conducted at a major IT company to investigate how employees legitimize knowledge and how it affects the transfer of knowledge between generations.

Gapet mellan teori och praktik i pappersprototypande : en studie i diskrepans mellan det ideala arbetssättet akademin förespråkar och hur praktikern faktiskt arbetar
This study presents an alternate viewpoint to the strive to overcome the gap between research and practitioners within paper prototyping in interaction design. Earlier research identifies three aspects of this gap, which is:Practitioners being unaware of interaction design methods and theoriesPractitioners being aware, but choosing not to apply these methods and theories, due to time, budget and constraints of labourPractitioners and research having different perspective on similar design issuesOur study was done by carrying out qualitative interviews with interaction designers based on two digital design bureaus. One of the bureaus has an expressed link to research: the other has not. Our hypothesis is that the gap would manifest as a difference in work practice between the two bureaus.Our study shows that the two bureaus have similarities in work practice and that this work practice is based on scientific methods and theories, but is adapted to fit the client and/or the project. We conclude that the overcoming of the gap might not be necessary.
En symbol går i graven - en studie av förslaget om Utlänningsnämndens nedläggning och införandet av en ny instans- och processordning i utlänningsärenden
Motives and reasons behind a decision to change the asylum process in Sweden are the central concern for this thesis. A symbolic political perspective will be applied in order to elucidate the symbolic factors that have influenced the decision process.The Aliens Appeal Board in Sweden will close down at the end of March 2006 and all pending and future cases will henceforth be decided by three administrative courts. This will be done in order to enhance the principles of legal certainty by making the process more transparent and oral. It is an extensive reform, but since very few amendments are made to the applicable substantive law it raises questions about the actual motives behind the change.One reason that seems to have had a major impact on the decision to close down the Aliens Appeal Board is the fact that the board is perceived as a symbol for an inhuman asylum policy. Transferring the process to the courts might ease the attempt to increase the legitimacy of the asylum process.
"Som om barnet heter Kalle" : - En studie av mottagandet av ensamkommande, asylsökande barn i Sverige 2008
The 1st of July 2006 Sweden made a change of authorities in the system concerning the reception of separated asylum seeking children. Prior to the change, the Swedish Board of Migration was held completely responsible for the reception of these children, who arrives in Sweden without their parents or any other relatives to care for them. Since the alteration of the law (1994:137) the responsibility for the housing of these children now lies within the Swedish municipalities, while the Board of Migration still handles their legal commissions. The change was intended to fundamentally improve the conditions under which these children were taken care of. However the implementation took a severe wrong turn when the municipalities weren't prepared for their new responsibilities and the immediate result was alarming. This qualitative study is based upon interviews with the people responsible for the reception of the separated asylum seeking children in the municipalities of Kronobergs County, as well as one of the two people in charge of the new system at the Swedish Board of Migration.
Metadon - drog eller medicin: en diskursanalys av Socialstyrelsens föreskrifter för läkemedelsassisterad behandling vid opiatberoende.
This thesis discusses the attitudes versus methadone assisted rehabilitation ad modum Dole Nyswander in Sweden during the period 1972-2004. This is done by means of a Foucault inspired discourse analysis applied on the directions issued by the Board of Health and Social Affairs. The context in which these directions were created is also described, in which scientific achievements on methadone treatments during the period, and the main actors struggling to establish and define the discourse on narcotics and narcomania, are juxtaposed to the effects of the work of the Board. It is stated that the directions were largely affected not by scientific results and knowledge on methadone, but by the symbolic connotations of narcotics in Sweden established in the discourse already in the mid 1960´s. Also during the end of the studied period, after the occurence of AIDS had begun making methadone more broadly accepted, the findings of this thesis showed that the legacy of the 1970´s symtomtheory and its severe antagonism against methadone, was still present, in effect, in the discourse around methadone and subutex assisted rehabilitation, and so in the directions issued by the Board of Health and Social Affairs..
Globaliseringens och professionaliseringens effekter på styrelsesammansättningen i svenska börsbolag: En social nätverksanalys baserad på delade styrelseledamöter under perioden 1990 till 2010
The purpose of this thesis is to examine the networks of interlocking directors in the 50 largestSwedish companies on the Stockholm Stock Exchange during the years 1990, 1995, 2000, 2005and 2010 and seek explanations for the observed developments.Our findings indicate that the density and concentration of the network has decreased during thefirst ten-year period and stayed constant during the second period. The development of theoverall network is not consistent throughout all corporate groups. Most notablyHandelsbankssfären seems to experience increased density and connectivity whileWallenbergsfären is experiencing the reverse.The changes during the first ten-year period is deemed to come mainly from changes inregulations pertaining to both the opening for international capital investments as well as looserrestrictions on domestic capital investments. These changes have caused decreased concentrationof ownership, as well as the emergence of new owners, which is reflected in the board ofdirectors.During the second ten-year period the changes are more pertaining to the individual boards andboard members, without flowing through into the overall network. Our findings indicate thatthese changes are caused by the increased professionalization of boards and board work, whichhas gained momentum through the creation of the Swedish Corporate Governance Code..
