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.

Inventering och riskklassning av förorenade områden i Öna och Östnor :

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

Att undervisa förskolebarn - förskollärares strategier

This study gives voice to which strategies preschool teacher?s use they teach preschool children in different performance tasks. The overreaching aim of this study was to find out what teacher give expressions to, verbally and in action, and what educating strategy they use when the purpose is that the children are to learn something specific. The theoretical starting-point of the study is a phenomenography research which aims in finding and systematizing of forms of thought in terms of which people interpret significant aspects of reality. The study has a Sociocultural perspective which means that the structuring occurs through choice of which activities children have access to observe and engage in, as well as through in-person shared endeavours, including conversations, recounting of narratives, and engagement in routines and play.

Sociala krav i byggentreprenader : En tillfällig trend eller här för att stanna?

Europe has, since the economic crisis of 2007, gained increasing social segregation. The gap between rich and poor has increased and the large number of hidden statistics regarding people excluded from the labor market is greater than in many years. Social exclusion has thus taken a toll on community groups that already before the crisis had a hard time getting included. Groups such as young, elderly, immigrants and people with mental of physical disabilities. To curb this development, the European Commission have, since the 2004 directives, enabled public sector clients to, through procurement of goods, services and contracts, include measures that promote social consideration.Social consideration is a term that have been a part of Swedish procurement legislation since 2007, and was updated in 2010.

Vidareutveckling av PV/T-receiver för koncentrerat solljus

The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power generating product. The product, Absolicon X10, uses a parabolic trough to concentrate the radiation of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media.

En uppgörelse med unkna ideologiers våld

Hedemyr?s project has been about finding a meaningful position of utterance and a language for her practice. The general theme is performative art in public spaces.This text is a meta-narrative about this development and transformation process. It is also a proposal for choreographic practice as text, and thus a suggestion for what performative text could be.Her master project includes three intertwined parts. The foundation is an ongoing ?doing?.

Starting in September 2004, Enter offers individually based coaching and job guidance to totally 110 young persons with problems entering the labour market. The goal is to provide these people courage to find either full or part time employment or to start study.

Analys av off-design prestanda för ett absorptionskylsystem

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

Att vara partner eller kontrollant. En studie av Sidas uppföljningskrav

External forces have significant impact on organisations. This study analyzes the implications of one type of external forces in aid-focused NGOs through two qualitative case studies where it is investigated if Sida?s reporting requirements have the intended effects: learning and control using a theoretical framework where it is recognised that the requirements may also result in dysfunctional behaviour: decoupling and colonisation. The study shows that when the demands are the result of institutional pressure rather than an ambition to generate learning and control, the demands tend to be unrealistic and the NGOs therefore decouple the formal fulfilment of the demands from the actual activities. It is argued that a partnership, which incorporates trust and dialogue, is a prerequisite, not only for learning, but also control.

Skogsskötsel för att minimera stormfällning över järnväg :

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

Kvalitetsutveckling inom socialtjänsten och införandet av SAS - Socialt ansvarig samordnare :  

This master thesis is based on a general issue of quality in social services. I have chosen to illustrate through an empirical case, namely the position social responsibility coordinator and shortened SAS.This position is fairly new to the Swedish social services and has the overall mandate to monitor, develop and ensure quality.To study this, I have developed two analytic schemes. One is based on the concept of quality value components, the second is based on the concept of quality character components. These analytical schemes are used as the presented material. When I study mycase, I have used two methods, documents and questionnaires.In this study I will try to describe how new solutions to improve the quality of social services can conform and develop.

Cross-language information retrieval : sökfrågestruktur & sökfrågeexpansion

This Master?s thesis examines different retrieval strategies used in cross-language information retrieval (CLIR). The aim was to investigate if there were any differences between baseline queries and translated queries in retrieval effectiveness; how the retrieval effectiveness was affected by query structuring and if the results differed between different languages. The languages used in this study were Swedish, English and Finnish. 30 topics from the TrecUta collection were translated into Swedish and Finnish.

Ett litet ord med stora implikationer : En studie om förståelsen kring ordet Gay i allmänt negativ bemärkelse

Many of us have grown up hearing or using words meant as insults or negative adjectives that were in fact names for social groups. Most of them have gone unquestioned in the mainstream consciousness, but the term Gay in the generally negative meaning has in the past years been given attention as offensive and homophobic, with debates emerging in response over whether or not this is true, particularly on the internet. It is the articles and forum threads from these debates that make out the empirical material for a qualitative study as I ask what these people?s thoughts are about this term and how it is perceived.After a qualitative coding and analysis of these texts, and interpretation of the results based on Erving Goffman?s theory of Phantom acceptance and stigma terms, Judith Butler?s theory of performativity, Ferdinand de Sassure?s theory of signifier and signified and how it connects to the community and Baudrillards theory of simulacra, this is the principal conclusion that I have drawn:For some of the people in this debate, the term Gay and its use is about homophobia and heterosexism, though mostly it?s not overt but a subconscious part of the continued dehumanization and stigmatization of homo- and bisexual people. This is a position I callThe socially focused skepticism.
