Detta arbete är ett examensarbete i matematik på kandidatnivå vid Växjö universitet. Det är en studie av kodningsteori i allmänhet med fokusering på cykliska koder och Reed-Solomon-koder i synnerhet. Reed-Solomon-koderna används för att skapa McElieces kryptosystem. En kortfattad analys av McElieces kryptosystems säkerhet görs tillsammans med en genomgång av kända sätt att forcera denna typ av kryptosystem. Här visar det sig att användning av Reed-Solomon-kod försvagar kryptosystemet i förhållande till om den ursprungligt föreslagna Goppa-koden används.

In Montessori pre-schools early reading and writing is an important feature. By tracing sandpaper letters with their fingers and voicing the sound simultaneously the children connect phonemes to graphemes and normally learn to write between the ages of four and five. 24 sixyear old children who attended Montessori pre-school and 26 six-year old children who had not attended Montessori school were assessed with a test assessing their linguistic awareness.The result showed that the Montessori children were more linguistically aware than the children who hadn?t received any literacy training. The scores of the Montessori children were highest on phonological awareness.

The aim of this study was to investigate the individual meaning of experiences of migration and day-to day life experiences before and after migration, of women that had migrated from the Middle-east area to Sweden. This was to be done with a psychological health perspective looking for stressors and salutogenic factors. A phenomenological approach was used. Eleven women where interviewed with three open questions on a trajectory theme. The analysis was supported by software Sphinx Lexica and software MCA-Minerva.

Examensarbetet utfördes på University of Florida vid Department of Mechanical and AerospaceEngineering i deras Energy and Gas Dynamics Systems Laboratory. Laboratoriet forskar på enny gasturbincykel som producerar kraft, värme, kyla och vatten. Cykeln är kallad High PressureRegenerative Turbine Engine (HPRTE) och kombinerat med gasturbincykeln är ettabsorptionskylsystem (VARS). Kylsystemet drivs av spillvärme från avgaser som cirkuleras igasturbinen, den producerade kylan används för att kyla ned högtryckskompressorinloppet.Syftet med det här examensarbetet är att undersöka möjligheten till att kyla ned inloppet tillkompressorn till temperaturer långt under fryspunkten för vattnet i den fuktiga gasen. Om gasenskall kylas till nivåer under fryspunkten måste vattnet föras bort från gasen.

Work Environment problems on construction work sites are very extensive and discussed. The construction industry is one of the most dangerous industries in Sweden. The construction industry occupies about 290 000 employment (2009), and the investment was 250 billion SEK. This report will investigate the issues of the work environment and offer advice on how these can be measured and imporved. The study includes review and analyses of occupational injury statistics, interviews, inspections and audit and review of the literature.

Two haematological instruments intended for small animal clinic use were evaluated at the Department of Clinical Chemistry, Swedish University of Agricultural Sciences (SLU), Uppsala, Sweden. The QBC-V and Vet abc were compared to a reference instrument, the Cell-Dyn 3500. Fresh blood samples were obtained from canine and feline patients from the University Veterinary Hospital, SLU. The QBC-V was used for 111 canine samples and 78 canine blood samples were analysed with Vet abc. From cats, 23 samples were analysed with both instruments.

Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

A QUALITATIVE STUDY ON THE EXPERIENCE OF ESCORT SERVICE UNDER THE ACT (SFS 1993:387) SUPPORT AND SERVICE FOR THE DISABLED The purpose of this study was to examine the experiences of escort service under the Act (SFS 1993:387) concerning Support and Service for the disabled (LSS) for self-determination, participation and equality of living conditions. In the results of this study appears that the escort service fulfills its role in breaking the isolation of persons with disabilities. It gives a picture of the escort service is much more than to break the isolation of people with disabilities. The aspects that emerges is that escort service gives persons with disabilities the opportunity to develop their independence, increase their self-esteem and broaden their frames of reference through increased participation in community life. All users report that they experience autonomy in the choice and order of activities within their grant initiatives.

C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.

The aim of this master thesis is to create an understanding of what it can be like to grow older as a homosexual man in Sweden today. The study has an intersectional and queer theoretical approach and is based on eight in depth interviews with men who are aged between 68 and 82 years old. In the analysis I deal with the problem of how sexuality can be inter- preted with the experience of aging. Central to the analysis is the criticism of norms connected to age, sexuality, social- and family life and gay culture.The results show that the norm-breaking sexual orientation of the men affects their life path in terms of how to organize social life, where friends often replace the traditional family. New ways of forming relationships and living their lives imply other obligations rather than the traditional for significant others, which was shown to influence the expectations and outcome of old age in terms of care and support.

Companies in the apparel industry are becoming increasingly responsible with regards to the social and environmental issues related to textile production. Despite these tendencies, there are great insecurities surrounding the concept of CSR and the effects on consumers of CSR communication. There is currently no model for breaking the concept of CSR down into smaller elements, specific for the apparel industry. In the first part of this thesis, we create such a model, applicable in a consumer communication context. In the second part, we investigate the effects on consumer attitudes and intentions of communicating the different elements of CSR presented in the model.

The First World War had a definite impact on all of Europe, not to say the entire world. The domain of art was no exception. In Zürich, neutral Switzerland, a group of young creative intellectuals who shared a hostile approach towards the structure of the bourgeois society, with its non-democratic rulers and current nationalism which lead up to the war, united under the artistic movement we today call Dadaism. After the war Dadaism sprung up in several cities throughout Europe, among those Berlin. In Berlin Dadaism became a socialist weapon of propaganda, with its norm breaking artistic manifestations, against the camouflaged conservative government of the new Weimar republic.

The purpose of this study was to estimate the removal of biomass in connection with thinning operations in young stands that are dominated by small diameter trees. The economy of such operations depends on the products generated as well as the performance of the harvesting systems. Conversion tables designed to predict the outcome based on harvesting method was another goal of this study. Removal of biomass affects the nutrient composition of the site. Therefore it is a purpose that this study will provide researchers with some variables that can be utilized when studying this aspect. Trees were harvested and divided into bunches based on diameter.
