Planeringsprocesser och kunskapsrepresentation - En studie om problemformuleringar och åtgärdsprioriteringar
I dagens planeringsprocesser inkluderas medborgare huvudsakligen genom samrådsprocessen. Detta innebär två huvudsakliga problem: Det första problemet är att medborgares kunskap inkluderas först efter att problemen för en planeringsprocess är fastställda. Det andra problemet är att det endast är de medborgare som närvarar vid samrådet som möjlighet att representera sin kunskap och sina åsikter. Uppsatsens syftar därför till att undersöka om och eventuellt hur olika kunskapsunderlag påverkar hur problem formuleras i stadsplaneringsprocesser. Vidare syftar uppsatsen till att undersöka hur inkluderingen av olika former av kunskap kan påverka vilka åtgärder som prioriteras inom stadsplaneringsprocesser.
Det huvudsakliga metodvalet har varit en fallstudie av Malmabergsgatan i Västerås.
Detektering av sprickor i vägytor med hjälp av Datorseende
This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

The purpose of the study is to investigate and elucidate how low-cost airlines can influence and develop tourism in a region. In order to bring about the purpose the author used two research questions. Have low-cost airlines contributed to regional development? How many additional visitors have low-cost airlines contributed to Stockholm? In order to answer these questions a survey was carried out at Arlanda airport and statistics were collected. The results of the study show that there has been a regional development.
Energikonsumtion hos en diskmaskin
The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.
Några elevers känslor och tankar i ett möte med en skalbagges livscykelstadier / A couple of pupils? emotions and thoughts when meeting a beetle?s life cycle stages.
Avsikten med detta arbete är att undersöka vilka känslor och tankar elever kan ha till djur, samt om de kan ändras när eleverna blir bekanta med djuren. Vi har valt att utföra en kvalitativ undersökning där vi kombinerar metoderna intervju och observation. Undersökningen genomfördes på tio elever i årskurs ett, där alla enskilt fick bekanta sig med en skalbagges alla livcykelstadier under ca 10 minuter. I början och slutet av varje intervju bad vi eleverna att berätta vad de kände och tänkte när de såg djuren, därefter grundade vi vår analys och tolkning av vårt material med hjälp av konstruktivismen.
I vår undersökning såg vi att alla elever hade någon sorts känsla för och tanke om djuren, dock kunde det vara svårt att tyda känslorna eftersom vissa elever verbalt kunde uttrycka en känsla medan kroppsspråket visade en annan.
Sociala rörelser i rörelse - En analys av de jordlösas rörelses verksamhet i civilsamhället
This thesis analyses the rise and fall of social movements. Social movementsfunctions in the civil society, by contentious collective action they form identities,mobilize their forces and use repertoires of contentions to make new or previouslyunaccepted claims. They function in a limited timeframe, sooner or later they getinstitutionalized, marginalised or succumb into violence. The landless movementin Brazil is one of the most profound social movements in the world; their majorgoal is a land reform. Since the leftwing president Lula da Silva won the Brazilianelection in 2002 the president has been unable to live up to the expectations fromthe landless movement about implementing a land reform.

Referenser i informationsåtervinning: utvärdering av en sökstrategi för citationsindex
In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.
Att värdera en hamnutbyggnad : en översikt av ekonomiska verktyg samt en värdering av föroreningar
När en kommersiell hamn byggs ut fordras omfattande muddringsarbete för att säkerställa ett brukligt djup för sjöfart. Då stora delar av muddermassorna ofta är förorenade av tungmetaller och miljögifter krävs särskilt omhändertagande av dessa. Traditionella omhändertagningsalternativ består av att deponera massorna på särskild avsedd plats på land eller tippa till havs, något som inte tillåts för förorenade sediment. En relativt ny metod är stabilisering/solidifiering (S/S) som innebär att muddermassorna behandlas med ett bindemedel för att sedan kunna användas som fyllnadsmaterial i exempelvis kajkonstruktioner. Dessa alternativ behöver noga vägas mot varandra med hänsyn till ekonomiska och miljömässiga aspekter.
Livet efter döden : Svenska tidningar anpassar sig till en digital framtid
The media industry in general and the newspaper in particular is going through major changes ? technological, logistical, economical ? due to the dropping sales and width of the printed daily newspaper. Few organisations have been spared the necessary rationalizations and cut-downs in staff. All of them are expected to produce more and better content, in more and new channels and platforms, with less resources. Some have been preparing for this a long time, others have never entered the digital world of news.
Energikartläggning av ett 1970-tals lägenhetshus på Skarpövägen i Nacka kommun : Simulering av energibesparande åtgärder i ?IDA Indoor Climate and Energy?
This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.
Elproduktion ur låggradig värme : Tillämpningsmöjligheter vid Skellefteå Kraft ABs kraftvärmeverk Skogsbacka i Lycksele
SammanfattningI ett kraftvärmeverk binds en stor del energi i de varma rökgaserna. Genom att installera rökgaskondensering kan energi från röken tillvaratas. På kraftvärmeverket Skogsbacka i Lycksele har man tittat på möjligheterna att installera rökgaskondensering. Detta arbete syftar till att ta reda på om och vid vilka förutsättningar det skulle vara lönsamt för Skogsbacka att också investera i utrustning för elproduktion vid låggradig värme, för att på så sätt använda energin från rökgaskondenseringen. Idag finns flera tillverkare som erbjuder fristående aggregat som kan utvinna el vid låga temperaturer.
Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet
This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.
Prestanda och precision pa? en enkortsdator i ett system med realtidskrav
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.
Historiska återspeglingar : En studie om svensk turismhistoria genom fallstudier på Åre och Mölle
The idea of this thesis emerged from our common interest to explore the life cycle of Swedish tourist destinations. This study has historical features since we tried to identify crucial historical and current push and pull factors, which influenced destinations upturns and downturns. In order to achieve our primary goal and identify those factors, we made two case studies. We chose Åre and Mölle as our cases and these two areas will represent Swedish destinations, and their life cycles, as a whole. The destinations? developing processes and their nowadays profile are not the same as for two hundred years ago which was a reason and motivation that made us start exploring this specific subject.
