Genomgång av Turbomin 100 : Förstudie och föreslagna förbättringar av undervisningsjetmotor Turbomin 100
ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?. The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

Introduction: Sleep is necessary for human survival. Difficulty sleeping occurs in about one in four adult person in Sweden, insomnia in every ten. There are several reasons for difficulty sleeping, where stress is one of the most common. The quality of life and health are affected negatively. Treatment with proven efficacy against insomnia is not only sleep medication, but also cognitive behavioral therapy, CBT.
Välkommen till Kanarieöarna. Våldsam skillnadspolitik i bemötandet av turister och båtflyktingar
This is a qualitative case study about tourists and boat migrants in movement to and in place on the Canary Islands, Spain. The aim is to study how these two groups of guests are treated differently, either as guests or strangers, based on how they move, illegally or legally, where they come from and where they have rights to go. To analyze the case I use theories of how differences in ethnicity, culture and religion etc. are created and recreated in society in interactions among humans and in the politics - the politics of difference. The politics of difference creates and recreates categories of mobility such as tourists and boat migrants.
Vad är Cloud Computing? : En kvalitativ studie ur ett företagsperspektiv
Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.
Vem bestämmer på bortaplan? - En fallstudie av Västra Götalandsregionens internationella engagemang.
The present study examines the demolition of a house on Hammarkulletorget in 1996 and the discourse of Hammarkullen, Gothenburg(Sweden), drawn from the perspective of historicization [?historisering?]. I have examined how the past played role inpresentations of Hammarkullen and how the past affected the decision to demolish a house. By examining which role the neighbourhood?spast time played in the perception of the neighbourhood, the thesis aims at providing a better understanding of howthe past can influence and legitimize major changes in the urban environment.In the early 1980s the image of Hammarkullen as a victim of negative publicity is established and this reputation lives beyond thesimplistic and negative descriptions themselfs.
Beslutsmodell gällande finansieringsform samt intern prissättning av ett företags truckpark
To be competitive in the corporate climate of today it is important to have effective logistic activities. A common resource within the internal logistics is forklift trucks, which are used to lift and transport material. It becomes more and more important to decide whether to buy, lease or rent the forklifts to obtain an optimal economic situation. Many companies have issues with internal pricing. It is difficult to price products and services correctly. It is common to price the overall instead of what it really costs.The purpose of the thesis is to present a model for the acquisition of forklifts for internal logistic operations, regarding financing and internal pricing, to obtain economic effectiveness and an optimal forklift fleet size. The study focused on a specific research question, and for this purpose interviews with experts were held, observations were made and a literature study was done.
Jämförelse mellan en träbro och en betongbro : En LCA-analys med fokus på koldioxidutsläpp samt en LCC-analys
This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.
En ekonomisk hållbar växtodling i sörmländsk mellanbygd :
We have been looking at three different types of agriculture in Södermanland, in the middle
east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is
to get an economic defensible plan for how to run different farm sizes. We also have been
looking at the working hours and how many hours the different types will give.
We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is
located 60 km southwest from Stockholm.
Vad är ?rätt? gjutkvalitet? Hur uppnås det?
Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
Att nyttja marken 30 meter från järnvägen : hur platser, syften och miljö vävs samman
The purpose of this work is to raise ideas and interest for land that is very much forgotten,unused and neglected in terms of maintenance and usability. Railroads are often seen as adirty and loud intrusion in the landscape and therefore cities turn their backs on them. Theland around railroads is not considered useful despite its often central location and scrublandis common in these areas.The starting point of this work is the restrictions and possibilities linked to the land withinthe security distance 30 meters from the railroad center. Within this security distance thereare numerous limitations and regulations due to the nature of railroad use. These limitationsare counted for in the initial chapter and lay the foundation for the rest of the work.
Presentation av taktisk information på bildskärm : Head-Up Display som stöd för tidsstyrd taxning med flygplan
Syfte: Syftet med uppsatsen är att tillämpa aktionsforskningsteorin och metoden appreciative inquiry vid design av en måltidsupplevelse med målsättning att öka medarbetarnas medvetenhet kring stolthet över arbetsplatsen, inspiration till matlagning samt mod och vad som får människor att våga testa nya produkter och arbetssätt. Ett ytterligare syfte var att utveckla ett mätverktyg som utvärderade insatsen och fångade upp medarbetarnas tankar och känslor. Till sist är det även uppsatsens syfte att utvärdera inbjudan till den designade måltidsupplevelsen för att kartlägga vad som väcker intresse och nyfikenhet samt vad som får medarbetare att anmäla sig för att delta på evenemanget.Design/metod: Arbetet är en fallstudie och har utgått från aktionsforskningsteori och -metodik med specifikt fokus på appreciative inquiry. Eftersom arbetet har varit tätt kopplat till utveckling av en målitdsupplevelse har även inspiration och kunskap hämtats från mat- och måltidsbranschen.Resultat: Ett nytt måltidskoncept har utvecklats och presenterats. Eftersom den designade målitdsupplevelsen fusionerar appreciative inquiry och måltidskunskap har det givits namnet appreciative dining.
Bedömning av oralmotorik och talmotorik med VMPAC hos typiskt utvecklade barn, 4-10 år
Syftet med denna studie är att undersöka hur en grupp typiskt utvecklade, svenska barn, i åldrarna fyra till tio år presterar på tre deltest i VMPAC, för att därmed skapa ett underlag för en referens för svenska barn i bedömningen av avvikande utveckling. Studiens frågeställningar är: 1. Hur presterar en grupp typiskt utvecklade, svenska barn, i åldrarna fyra till tio år, på tre deltest i VMPAC (Focal Oromotor Control, Sequencing Maintenance Control och Connected Speech and Language Control)? och 2. Förekommer det några skillnader mellan en grupp typiskt utvecklade, svenska barn, jämfört med den amerikanska normeringen i VMPAC och barn med verbal dyspraxi (CAS) undersökta inom ramen för en magisteruppsats (Björelius-Hort, 2009)? Oral- och talmotorisk förmåga hos 23 svenska barn i åldrarna fyra till tio år, som åldersmatchats mot barn med verbal dyspraxi (Björelius-Hort, 2009), testades med deltest två, tre och fyra ur VMPAC.
Spårvägskonstruktioner : Underlätta valet av spårvägskonstruktion
Stockholms spårvägar växer i allt snabbare fart, och det är allt fler kommuner som är intresserade av den typen av transportmedel. Något som idag är en brist inom spårvägsindustrin i Stockholm är kunskap och erfarenhet om spårvägsämnet. Drift och underhåll har varit minimal eftersom det inte har prioriterats sedan Tvärbanan öppnades. Detta har lett till för tidig reinvestering av gatuspår i mångmiljonbelopp.Då det förekommer olika förutsättningar som måste tas hänsyn till i form av buller, mån om plats och geoteknik finns det många konstruktioner att välja mellan när en spårväg ska byggas. Denna rapport har som syfte att underlätta val av spårvägsinvesteringar i framtiden.
Wilhelm Reichs mottagande i Sverige psykoanalys, marxism, biologi och kosmologi
In this essay I have been writing about the psychoanalyst Wilhelm Reich. It was written at the Library School in Borås as a contribution to the struggle of the maintenance of the free word. In the essay I have been concentrating on how Reich was received in Sweden from the publication of his first book 1927 to the year of 2000. The work started with a biographical chapter and a chapter about Reich's scientific development, which was divided into three phases: one psychoanalytical and Marxist, one physiological and biological and a third phase that makes a synthesis of these in a cosmological form. The analytic material has been books and articles from periodicals and papers.
Dissekering av ett lokalsamhälle : En studie av sociokulturella mönster på småländsk landsbygd 1838-1845
Following essay examines the social and cultural patterns of southern rural Sweden between the years 1838-1845. The study is based on records from trials held by the district court of the district Norra Möre, which provides an insight to the everyday life in rural local community. Emphasis is put on exclusion and inclusion: the basis for community, codes for inclusion and exclusion, meaningful attributes, social and cultural capital etc. Questions concerning gender are raised as well as intents to discover whether modern ideas contrast early-modern, especially considering the process of individualization. Results show that concepts of confidence and trust were extremely valuable and possessed significant meanings. Confidence, which established itself on virtuous and honest life, created the framework for most aspects of social society: for example credibility inside and outside of court, maintenance of friendship and company, capacity of upholding a working life. Forfeit of trust, through extensive dissolute, mischievous and ill-considered way of life meant exclusion from the community and great vulnerability.
