Digitalt textiltryck ger mig möjlighet att skapa textilier av hög kvalitet i små upplagor utan begränsningar vad gäller rapportstorlek och färgantal. Jag kan producera hållbara och praktiska textilier med en handgjord känsla. Dessa egenskaper ger tekniken intressanta möjligheter som en överbryggare mellan design och textil konst/konsthantverk. Det ger också stora möjligheter att anpassa formgivningen efter en specifik möbel eller miljö. Detta vill jag utnyttja i mitt arbete.
CFD simulering av en fyrtakts Otto motorcykel motor
This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.
Lamellrandsröta i hästhoven :
SAMMANFATTNING
Jag har skrivit om en hovsjukdom som drabbar hästar, den engelska benämningen är White
line disease. Det finns inget korrekt namn på svenska, men vi kallar det för lamellrandsröta.
Den engelska benämningen är den mest använda.
Sjukdomen kom in i Sverige i slutet av 1980-talet, man tror att det var via importerade
travhästar från USA. När den i slutet av 1990-talet fick fart i Sverige började den också att bli
ett problem.
Ambitionen är att få en inblick i vad lamellrandsröta är och vad den samlade kunskapen är
idag bland fackfolk och praktiker. Godtyckligt har jag valt ut och ringt runt och intervjuat ett
antal personer som har stött på detta problem, hovslagare, veterinärer och hästägare. All fakta
som inhämtats har jag sammanställt, men det finns fortfarande många frågetecken att reda ut.
Ett bekymmer är att expertisen har så varierande kunskap och syn på sjukdomen.
Idag vet man att det är anaeroba (syreskyende) organismer som orsakar rötan.
Komfortsanalys med hänsyn till vibrationer orsakade av människoaktiviteter. : Ett modernt dimensioneringsproblem för huskonstruktörer
Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.
Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå
Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.
Ger man sig in i leken, får man leken tåla- eller? : En kvalitativ intervjustudie med poliser om våld och hot i arbetslivet
Våld i arbetslivet har de senaste tio-femton åren uppmärksammats inom den kriminologiska forskningen. Tidigare sågs ämnesområdet som tämligen ointressant ur forskningssynpunkt, främst eftersom våld i arbetslivet skiljer sig från det traditionella ?gatuvåldet?. I tidigare studier har man intervjuat vårdpersonal och restaurangpersonal där resultaten tyder på att personalen blir utsatt för våld, men att våldet ses som en del av arbetet.Denna studie består av kvalitativa intervjuer med fem poliser om deras upplevelser av våld och hot i arbetslivet. Studiens syfte är att undersöka vad poliserna själva upplever som våld och hot samt om de anser att de måste tåla en viss typ av våld eller hot i tjänsten.
Östersjöledningen : En studie i åsikter och människors trygghetsupplevelse belyst av media
The Nord Stream natural gas pipeline has been a controversial project. The debate was primarily escalated by Poland's strong negative reaction to the project in the spring of 2006 over safety and security and then alternated back and forth in Europe until the approval by the nations most concerned in the Baltic region during the autumn of 2009.In the case study an approach is used that primarily maps out the media image of the various viewpoints that deal with the pipeline and how these viewpoints position themselves, primarily through political and environmental dimensions. Simultaneously there?s an attempt to map out the spatial spread of the media image views as to the proximity and distance to the pipeline in Sweden, Poland and Germany. A key question is whether distance or proximity to a large facility can affect people's attitudes.A parallel focus of the study is to explore the role of the Nord Stream natural gas pipeline in the cross-border hinterland region of Szczecin-?winouj?cie.
Hållbar och framgångsrik? : samband mellan hållbarhetsprestanda och finansiella aspekter i börsföretag
Many companies have historically forced their interests through without any thoughts about the future needs of the humans and the society. In the last few years voices have been raised for a change, companies need to take their responsibility regarding sustainable development.The purpose of the report is to describe and explain possible relations between sustainabil-ity performance of companies and profitability, valuation, industry and size respectively.To be able to judge the sustainability performance of the companies Folksam (2006a) have been used. This is a solid investigation of the companies listed on the A- and O-lists of the Stockholm Stock Exchange by the end of 2005. The sustainability marks have been com-pared with the chosen key values for each hypothesis respectively. With this quantitative data as foundation, a quantitative approach and a deductive method have been used.In the first area of the investigation, profitability, the authors found correlation for the main hypothesis between sustainability performance and ?Return on Total Assets? through a statistical test.
Holmes och Watson ? Ett Queerläsningsäventyr : En undersökning av maskulinitet och sexualitet i Sir Arthur Conan Doyles The Memoirs of Sherlock Holmes
This thesis is a queer masculinity reading of Sir Arthur Conan Doyle?s short story collection The Memoirs of Sherlock Holmes (1894). The analysis focuses on the dissonances, tensions and queerness that reside within the text itself. This has been done from my problem statement: How is Sherlock Holmes and John Watson?s sexuality and masculinity portrayed within the boundary of the text? What is being said, what is hidden, and what is dealt with silently? To reveal these queer parts this analysis has been focused around five themes: the late Victorian male, the Woman, countertypes and decadence, the homosocial sphere and sexuality.
Landskapsideal : hur uppväxtens landskap formar individen
The landscape can be something that you rest your eyes on, something that goes quickly past outside the windscreen or the place for the daily work.
To me, landscape is everything around us ? the city, the field and the forest. But what is landscape for you? What does the idea of the landscape stand for? How does our view of the landscape become influenced of the place where we grow up? And the differences between peoples different views of the landscape ? what does they depend on?
My point of the view for this paper is that the landscape ideals mostly depend on the landscape where you grow up and that it depends less on the differences between the individuals.
As a landscape architect the idea of the landscape is the essential. The more we learn, the more we realize how complex it is, but deep down we always have our own experiences and memories and that shapes our personalities.
Pallhantering på Findus - Flöden , problematik och alternativ
The purpose of my task was to map the pallet flows at Findus and put together as well as analyze the problems. My work has also included finding out what alternatives there are to the present pallet exchange system and suggest measures to reduce the problems.The problems can be divided into poor quality and hygiene issues. The poor quality, for instance poor strength is due to arbitrary judgements and the fact that there are companies that make a system of manufacturing forged pallets of an inferior quality compared to the EUR-pallets. These pallets are marked with stamps more or less similar to the EUR-mark and taken into the exchange system. Of course there are rules how to judge a pallet but these rules are many and sometimes indistinct and there are a lot of marks to keep track of.The most dangerous part is when the pallets lack the prescribed carrying capacity.
Cirkelformen i landskapet : funktionen och användningen av cirkelformen i landskapsplaneringen
The Circle is a strong form that influences the landscape. It also has symbolic value which influences our feelings and experiences. This Thesis project examines the Circles? characteristics and its significance in various connections. The goal of this Thesis is to examine what role the Circle plays in various situations and what motives there are for using it is landscape architecture.
The basis for this Thesis work is a proposal which has been drawn up for development of the rural area between the villages of Hofterup and Löddeköping in the municipality of Kävlinge.
Health added-value food : the Swedish retail market
Diet and lifestyle are closely interrelated and believed to have a significant influence on four major public diseases - cardiovascular disease, cancer, hypertension and obesity, but also affects functional deficiencies like gluten- and lactose intolerance. Health added-value foods are thought to reduce health-related risks or delay the onset of these major diseases. Therefore, interest among scientists, researchers and the public in general has been growing remarkably over the last decade regarding these special foods.
The Swedish market seems to be a good target for health added-values food. However, as there are many risks and cost factors involved for companies to enter the market or invest in R&D, it is important to take a step back and analyze the current market situation.
Utsidan räknas : ?En materialstudie
Judged by appearance. This is the conclusion of research made on shopper behavior that revealed that consumers tend to go by their instinct when evaluating vacuum cleaners in a purchasing situation. Many buy the first vacuum cleaner they interact with and few buy pre-planned brands. Almost none even turn the machine on before taking a purchase decision.Electrolux Floor Care Europe has their factory for vacuum cleaners in Hungary. Increased competition from China makes it harder to "only" produce vacuum cleaners with good performance.
