Test och verifiering av en ny inkapslingsmetod för SiC BJT och MOSFET

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

There are many different online dating sites to choose from depending on the users? objective.

Lärande på lika villkor : En intervjustudie om individanpassad undervisning i ämnet svenska

This study is a survey concerning learning on equal terms. The purpose of the survey is to get a look into how teachers of today integrate students to obtain an individually adapt education. A good education is where every single student can evolve from an individual level and how education is adapted to let high-achieving students keep their motivation and thus develop from their own level of knowledge.Data has been collected through a qualitative method using semi-structured interviews. In the result the answers of the interviews are presented and it shows that teachers turn their focus towards low-achieving students. Low-achieving students are more in need of support to reach the required amount of knowledge, but that the high-achieving students must not be forgotten by the teachers. .

In the second part of the study we used qualitative textual analysis to study two companies sustainable reports. The theoretical framework of the study is based on theories of CSR and how to communicate it.

Testning och parprogrammering : Går det att effektivisera testning med hjälp av parprogrammering?

The purpose of this study was to investigate the possibility of streamlining the test process by utilizing pair programming. During the process, pair programming has been practiced as is defined by the Extreme programming (XP) software development methodology, with the other aspects of XP discarded. The focus of the testing itself has been toward unit testing. The methods applied has been with an experimental approach where 93 cases were attempted to be solved by either single programmers or pair programmers. What has been investigated in these experiments was the time needed to complete a case, how many test attempts were needed to solve the case, and how high a percentage of the cases were solved.

Effekten av specialpedagogiskt stöd och senare resultat i grundskolan : en pilotstudie

A pilot-study was used to investigate, types of assistance, assessed needs, outcomes and effects of special-needs assistance given to a subsample of compulsory school pupils in an effort to develop an evaluation strategy for identifying educational impacts of specific special-needs inputs.  Preliminary results indicate a tendency for postive outcomes for most pupils in the pilot group (n = 11) but also that many pupils have residual difficulties.  Pupils with residual difficulties mostly required special education asssitance with Maths, English or Swedish.  More pupils also needed support with behavioral difficulties.  More research and an expanding knowledge base is required in order to effectively evaluate outcomes of teacher support.  Schools need help in devising different methods of assistance and particularly for pupils with behavioral difficulties..

Grovmotoriska färdigheter hos elever i årskurs 6 i Stockholmsområdet : En observationsstudie utifrån NyTidstestet

Syfte och frågeställningStudiens syfte är att, utifrån NyTidstestet, undersöka elevers grovmotoriska grundfärdigheter i årskurs 6 i Stockholmsområdet.Utifrån detta syfte har vi valt att använda oss av följande frågeställning:- Hur ser de grovmotoriska färdigheterna ut för elever i årskurs 6, när de bedöms enligt NyTidstestet?- Vilka skillnader framkommer, hos eleverna, mellan de undersökta stationerna?MetodFrågeställningen har besvarats genom en observationsstudie på sjätteklassare i Stockholmsområdet, sammanlagt 113 elever. Varje elev har observerats utifrån NyTidstestets observationsschema, där eleverna vid sju stationer bedömts enligt fyra kriterier: "mycket tillfredställande", "tillfredställande", "små brister" och "stora brister". Varje station innehåller en eller två grovmotoriska grundformer.ResultatDe undersökta elevernas grovmotoriska färdigheter är bristande. Hela 48 procent av övningarna kunde inte utföras på ett tillfredställande eller mycket tillfredställande sätt.SlutsatsUndersökningen visar att eleverna får en allt sämre grovmotorik och i och med den nya läroplanen (Lgr 11) tror vi inte att elevernas grovmotoriska färdigheter kommer att bli bättre.

EC Legal Regulation of the Insurance Market; Challenges of Integration

Over the last decade, the private insurance market has undergone a stable growth in turnover and growing demand for insurance products in all Member States of the European Union. Therefore, the creation of a single market in insurance will enable consumers to have access to wider choice of insurance products, and insurance companies to gain access to markets in various Member States and compete effectively. The EU legal framework for the insurance industry embraces the Treaty freedoms of services, establishment and capital, the EC Directives and the ECJ case-law. The present thesis identifies numerous factors that hinder the Community insurance market integration and offers possible remedies. The summary of the market obstacles is all-inclusive and reflects the responses to the questionnaires and the Commission surveys.

Varför En Reformerad Gymnasieskola 2011? : En reformanalys utifrån rektorer och lärares uppfattningar ? kopplat till John Deweys teorier.

This empirical work and base has been to analyze the government?s investigation (SOU 2008:27): the future road ? a reformed high school, which led to the high school reform that the Swedish government introduced as proposition (2008/09:199) about: Higher demand and quality within the high school. Skolverket (part of the Swedish government) has worked with the development of this steering document within their own mission Gy2011 in connection with the high schools during the transition. The reform comes into effect 1 of July 2011. This led to the main purpose to ask questions what high school principals and teachers think of the reform and to what extent it effects the high school programs, the examination system, what impact they see on the individual and the demand from society, and to some extent what the respondent´s answers about the government?s definition of what the higher demand and quality in the reform signify.

Solceller som energikälla och solskydd för tält

This degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for command and camp in the new force called Nordic Battlegroup, NBG. The demand on the equipment is firstly that it should have a small weight to be easy to transport and handle and secondly to be easy to bring up fast. Therefore the choice of solar cell technology fell on thin film cells.
