Detta examensarbete utfördes våren 2007 på industriverkstaden Ducorail i Luleå. Målet med examensarbetet är att få in tre nya arbetsstationer i den nuvarande produktionskedjan, dessa tre stationer är en demontering/monterings station för cylindriska lager, och en liknande station för TBU lager samt att en tvättanläggning ska nyinstalleras. Den befintliga kedjan ska ses över eftersom en del stationer kan hamna i vägen om man låter dem vara kvar. Utan omorganisation skulle det leda till onödigt truckanvändande eftersom hjulen måste lyftas över stationer som ligger felaktigt. Några alternativa lösningar togs fram, efter utvärdering av dessa valdes en idé att arbeta vidare på.

The aim of the study is to investigate the practice of psychoanalysis with infants, and its effect on mother and child. With psychoanalytical thoeries and contemporary research on infants interaction as a basis, five interwievs with psychoanalysts in practice has been done. Also taking part of a clinical meeting with nine psychoanalysts has been done. Two of the interwieved analysts where part of this meeting, therefor the total sum of twelve psychoanalysts who reports their thoughts about the process i infantanalysis. The study also includes three participating observations of infantanalysis.

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are included and significance tests are conducted. The study is based on information regarding CEO compensation, and possible factors affecting the compensation, from 267 companies listed on the Stockholm Stock Exchange A- and O-list in the year 2004. We find that the board structure has no significant effect on the CEO compensation.

The landscape in the interior of Norrland has undergone dramatic changes since the deglaciation as a consequence of faultings, earthquakes and tilting of the landscape westwards. Archaeological investigations along former shorelines by the use of models of isostatic land uplift, have revealed many Mesolitic settlements in northern Sweden. Döudden, in the county of Arjeplog, has been investigated by archaeologists that identified settlements from 5200 BC. The objective of this study was to analyse the history of the vegetation and if the vegetation showed traces of human activity during early Holocene, by pollen analysis. The results indicate that the area had an established vegetation c.

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.

I detta arbete har jag studerat rörelsens betydelse för inlärning, vilket har visat sig vara av stor vikt. Jag har dessutom studerat språk och inlärning och ur detta material framkommer att det finns mycket som spelar in vid språkinlärning, såsom motivation, ålder och härkomst. Dessa två huvudämnen, rörelse och språk, ligger till grund för min avslutande del i examensarbetet, där dessa bildar en kombination för andraspråksinlärning. Jag har funnit en metod för andraspråksinlärning som utgår från rörelseövningar. Denna metod heter TPR (Total Physical Response) och har arbetats fram av den amerikanska professorn James J Asher.

This master thesis in economics discusses the time use of today as well as the observed trends in time use over the last 20 years in Sweden. This is done by analysing time-use and consumption data at the microeconomic level, i.e. by explaining individual behaviour given the economic assumption of a rational behaviour. We reach the conclusion that the value of time is an important explanatory variable concerning the rationality in that time is used differently by different individuals and in the changed use of time. Furthermore, other variables such as social norms and the process benefit of a certain activity, i.e.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The aim of this essay is to examine how gender is described in pictures in textbooks used in swedish upper secondary school. The research question is: How is gender being potrayed in the pictures of new age in the textbook in relation to traditional dichothomy, hierarchy and detraditionalization? The material used in this study consists of five textbooks in religion used for education in upper secondary schools in Sweden. In total, 18 pictures from these books that describe new age, constitutes the subject of analysis. The method used is picture analysis.

Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.

Operationsavdelningen på Hallands sjukhus Varberg har genomfört ett förbättringsprojekt för att se hur flödet med att ge lokalbedövning (blockad) inför operation kan optimeras. Projektets mål var att spara tid på operationssalen genom snabbare byten, förbättra miljön för patienter och personal och samtidigt säkerställa fortsatt god patientsäkerhet och gott bemötande.Jag har valt att göra en fallstudie av projektet för att se hur förbättringsarbetet fungerat och hur gruppens förståelse utvecklats. Jag har gjort en deskriptiv undersökning och utgått från ett kvalitativt angreppssätt. Informationen har samlats in genom deltagande observationer av gruppens arbete och utvärdering av dokumentation.Som lösningsmetod har jag utgått från PDSA-hjulet, (Plan, Do, Study, Act) och tillämpat ett antal olika förbättringsverktyg för att analysera och beskriva verksamheten.I projektplaneringen har jag använt Tonnquists projektmodell. Resultatet har utvärderats genom tidmätningar, en loggbok som förts under testperioden och en enkät för att samla in medarbetarnas synpunkter.

Everyone has to take a greater responsibility in energy issues, both individuals and companies. There have been some major developments in the construction industry but there is still a lot to be done. This diploma work thesis presents different methods of making existing construction shed establishments to use less energy. What is possible to do and how much energy is there to be saved? A shed establishment consisting of 8 shed units were studied in this project and the building simulation tool VIP-Energy was used to simulate different types of material in the sheds. An infrared camera was used to locate thermal bridges. There are several factors that can be improved to make a construction shed establishment to use less energy.

Intelligibility is a central concept in speech-language pathology regarding assessment and treatment of speech. At present, there is no reliable or valid Swedish test for measuring intelligibility. The main purpose of the current study was to conduct a clinical trial of the computer-based intelligibility test ?Swedish test of intelligibility for children? and to investigate the test?s reliability. Another purpose was to investigate the reliability of the rating form ?Intelligibility in context scale?.

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

It might seem obvious that public opinions should be included in the planning process. However, it is not clear to what extent. Statutory forms of public participation attract little interest since many people feel that it is hard to make a difference. The purpose of this study was to engage those that normally do not get to speak their mind in the planning process. In this study, two methods for conducting ?on-street surveys? were investigated.
