Implementering av höghastighetsgränssnitt i 0,15 µm halvledarprocess
This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.
Design av PID-regulator baserad på kommersiell processormodul
The idea to develop a platform for a PID-controller came from the need to control the temperature in an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.
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.
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.
Fascia Panel Redesign
The purpose of this project has been to cut production costs for the fascia panels ofGetinge?s largest autoclaves. The cost for the stainless steel plates currently used is veryhigh. An alternative material solution could cut costs significantly.In addition, improvements have been made to the instrument tower which is a central partof the fascia panel. As a result of the new modular design in a new material theinstrument tower has been improved in several aspects..

Intensive family therapy (IFT) was developed during the 1970s with the purpose of helping families. The theoretical mainlines upon which the IFT ? model is based is the, structural-, strategic- and systemic perspective.
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..
Konstruktion av värmespridare med grafit för flygelektronik
This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalconductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.
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..
