För att kontinuerligt bibehålla ett flygplan i ett säkert och luftvärdigt tillstånd så krävs både stora och små ingenjörsmässiga åtgärder, ur drift- och underhållssynpunkt. En av de större åtgärderna är att byta ut motorn på ett flygplan till en starkare motor för att förbättra prestandan, vilket leder till att i synnerhet få en kortare startsträcka. Det här examensarbetet behandlar just en sådan modifiering, nämligen ett motorbyte på en Cessna 172. Flygplanets nuvarande motor är utsatt för korrosion och måste snart bytas. Då skulle det kunna vara lämpligt att byta till en starkare motor för att förbättra startprestandan.

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

This thesis aims to study how teachers develop pupils' motivation to read. Using qualitative interviews, three Swedish middle school teachers describe their experiences regarding pupils' motivation to read. They comment on how they attempt to stimulate motivation and the conditions and circumstances they experience while carrying out their work. As a basis for the teacher interviews, their pupils completed a web based survey about how they value reading as an activity and how they see themselves as readers. An analysis of the interviews raises several issues for discussion: pupils have different needs, good readers are described through their abilities, not through their experiences or reading habits, and teachers feel they can be limited to implement the teaching they think is necessary to promote reading abilities.

This study centres on learning to read and methods for teaching reading skills. The aim is to provide a survey of the concept reading skills and the methods developed on the basis of different theories and the methods preferred when teaching children in primary school and why. The study is based on interviews with eight teachers who are working on a dailybasis teaching Swedish in preschool class or lower primary school. The result of my study is that the majority of teachers do not use a specific method, but rather combine several different methods, thus adapting instruction to each individual pupil. .

AbstractThe aim of this study is to find out how the central content of the compulsory school curriculum (Lgr11) is handled in three teacher?s manuals for instruction in reading and writing for grade 1, and how these consider interaction and variation in learning how to read and write. Through a qualitative analysis with a hermeneutic approach, the three teacher?s manuals in Swedish for grade 1 were subjected to a close reading. The result shows that parts of the central content of the curriculum are considered, but that it is by studying exercises and texts that these become visible.

Developing good reading skills is crucial for all pupils in school, and the reading bookis a tool for achieving that. Pupils are entitled to good reading instruction, regardless ofwhich reading level they are at, and regardless of the level of the reader they have beengiven. The aim of the study is to examine a particular teaching material and describe thedifferences that exist between a simpler and a more difficult variant of the same reader.The study is a textual analysis focused on the two readers for grade 2 from the materialDiamantjakten (The Diamond Hunt). The study shows that the two books display greatdifferences. Reading the simpler book involves a smaller amount of text, fewerdescriptive expressions, and a smaller number of words, but it does make demands onthe reader?s ability to read between the lines.

This is a thesis performed at GEMS PET Systems AB in Uppsala. GEMS PET Systems AB is a company within GE Healthcare. GEMS PET Systems develops and manufactures equipment for manufacturing of radioactive isotopes for PET which is a scanner used in medical applications. The systems includes an accelerator of cyclotron type and other support equipment. One system is shipped in two or three containers depending on order configuration.

This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.

Abstract The aim of this study is to find out how teachers view the importance of reading in the teaching of foreign languages. In relation to this, we wish to gain understanding of what teachers want to achieve with reading, how they choose texts and what difficulties they encounter in getting their students to read. Six teachers from three different upper secondary schools in southern Sweden were interviewed for the study. We also examined the text-materials that they were using for their instruction. The findings show that students read mostly adapted texts from textbooks and, to a limited extent, authentic materials.

Studien syftar till att undersöka lärares uppfattningar om läsförståelseutveckling och om hur läsförståelseundervisning. Det är en kvalitativ studie inspirerad av fenomenografisk metodansats med halvstrukturerade intervjuer som datainamlingsmetod. Resultatet visar att det finns en variation i lärares uppfattningar om vad som utvecklar läsförståelse och hur läsförståelseundervisning ska genomföras. Det som framkommer i intervjuerna med pedagogerna är att de flesta vill och försöker arbeta medvetet med sin läsförståelseundervisning men att det till stor del förekommer mest implicit undervisning. Resultatet påvisar en tendens till att eleverna blir sittande att genomföra uppgifter på egen hand eller i par och pedagogen blir instruktionsgivare och kontrollant istället för undervisare och övervakare av elevernas läsning.

This study investigated the effect different contexts have on personality items when they are framed more neutrally. The study was based on a five-factor personality inventory originating from International Personality Item Pool. The inventory consisted of 50 original and 50 neutral personality items and in addition 28 items measuring social desirability. The sample consisted of 150 students from the Department of Psychology, Lund. The students were divided into three instruction groups differing in context.

The following essay describes a study made in Sweden in the autumn of 2010 at Södertörn University. The main purpose with this study is to find out and describe how people´s own understanding of being multilingual has influenced them. The objective behind this is to create a wider understanding for the phenomena. Therefore, the phenomenological perspective is used to describe the subjective reflection of a phenomena, in this case multilingualism. A qualitative method is being used for data gathering, implying conversational interviews with six multilingual people born in the 1970s and 1980s.The results show that the people interviewed mostly use their mother tongue in conversations with their parents and relatives today.

The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.

The purpose of this thesis was to develop and optimize a method of analysis for combustion of organic chemical products, followed by an ion chromatographic quantitative analysis. This was to be achieved with the decomposition equipment IKA AOD 1. The aim was to receive a precise and repeatable method that would be able to be applied to the process of qualification and technical marking of chemical products at the company, OKG AB in Oskarshamn. A complete instruction for the decomposition equipment and the method of analysis was written. A number of parameters were chosen from the general method of the combustion equipment, which then was tested parallel with a simultaneous development of an appropriate ion chromatographic method.
