Turkiet och Europa : En studie i identitetspolitik

The purpose of this Masters-thesis is to examine the impact of identity politics on (a) Turkey's foreign policy towards Europe and the EU, and (b) Europe's/EU's political attitude towards Turkey, and what implications this may have on a possibly future Turkish membership in the EU. It is a more interpreting thesis than it is an explaining one. The examination shows that Turkey has considered Europe as a political model, while Europe has used the muslime Turkey as a threat to determine its own identity. The negotiations between EU and Turkey this autumn will have great impact on the identity of both sites. If the EU accepted Turkey as a member, the union could gain a chance to spread democracy to the islamic world and thereby earn global respect.

Förebyggande Brounderhåll

AbstractThe Swedish Road Administration in the region of Mälardalen has since 2004 worked to in¬crease the efficiency of the maintance of bridges based on limited functional requirements and time demanded action.The maintenance of the bridges is contracted in the county of Uppsala since 2004, and Örebro since 2007. The county of Nyköping and Västerås is contracted by the traditional system. The contractor will perform a regular maintenance on all bridges. The bridges are inspected by the contractor at least once every year.The contractor registers the result of the inspection in a database called BaTMan. BaTMan is a Bridge and Tunnel Management system and is a strictly web solution were the user logs in via the internet.The Swedish Road Administration also inspects the bridges to se that the demands on the bridges are followed.My work is to compare these different inspections and to see any development..

Integrerat brounderhåll

Trafikverket ansvarar för det statliga vägnätet i Sverige. Vägnätet består av cirka15 500 broar som ständigt utsätts för olika former av nedbrytning. Broarnabehöver därför underhållas med jämna mellanrum både för att hålla broarna i ettbra skick och för att motverka att nedbrytningen påskyndas.Under de senare åren har Trafikverket utformat en ny upphandlingsmetod avbrounderhåll. Den går ut på att allt brounderhåll för en region paketeras, i ett s.k.brounderhållspaket, som en entreprenör sköter i en femårig period. Ibrounderhållspaketen ingår förebyggande underhåll, avhjälpande underhåll ochakut underhåll.Syftet med det här arbetet är att följa upp den nya formen att upphandlabrounderhåll i paket.

Prolog, Klimax och Katastrof : en återfallsförbrytares upplevelser och tankar om kriminalitet ur ett tidsperspektiv

The goal of this qualitative essay is to approach the knowledge of people who commit crimes. From a development psychology point of view, questions relating to childhood ang growth are some of the important subjects we choose to discuss. Our purpose is also to reveal the linkage between criminal behavior and different theories of the above mentioned perspective. To bridge the gap between the general and the individual, our survey was based on profound interviews with four inmates in prison.

Konstruktion av pipelinebro i Charagua, Bolivia

Guazuigua is a small village in Bolivia, which has had too small water resources, especially for irrigation. A project started after some studies were made, to create a canal to provide the village with water from a nearby town. To make the canal work it had to cross a dried out river. There have been several attempts to cross these dried out rivers, but with poor results. The purpose of the report is to provide a solution for this problem.

Biblioteket som en väg in i det svenska samhället ? En textanalys av styrdokument på Malmö, Stockholm och Umeå bibliotek

This thesis is about how the library can help immigrants integrate into theswedish society. By studying leading documents of the libraries in Malmö,Stockholm and Umeå in search for how the relate to work consideringimmigrants and integration I have studied the library as a bridge betweenbeing included and excluded in the society. The thought is that the libraryopens the door to new worlds both for immigrants and born swedes toobtain knowledge about a culture different from their own.In my thesis I reached the conclusion that library on a day to day basisworks with the integrationprocess for immigrants. Although the leadingdocuments should evolve since they show gaps and seem somewhatmisguiding in their presentation of the libraries function. The librariesshould work more with analysis of the environment that they are active in sothat they are more individualized for the people around it.

Development and evaluation of environmental enrichment for captive Humboldt penguins

Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

Underhållsfria material i broöverbyggnader : Fördelar ur kostnads- och miljösynpunkt vid användning av rostfritt stål och direktgjuten betong

En stor del av Trafikverkets budget går till att reparera och underhålla våra broar. Underhållsåtgärder orsakar också trafikproblem med stora miljöutsläpp och samhällskonsekvenser som följd. Eftersom broar vanligtvis dimensioneras för en lång livslängd på 120 år är det viktigt att planera för långsiktiga lösningar och förutse konsekvenserna av kommande underhållsåtgärder. Genom att använda mer underhållsfria material finns möjligheten att minska kostnaderna och koldioxidsläppen.Målet med examensarbetet är att ta reda på hur stora besparingarna är genom att svara på frågan: ?Vilka fördelar erhålls av att använda mer underhållsfria material i broöverbyggnader ur kostnads- och miljösynpunkt??.

Konstruktion av PID-reglerad motorstyrning

Denna högskoleavhandling beskriver konstruktionen av ett system vars funktion är att PID-reglera ett linjärställdon kopplad till venturi. Syftet har varit att få fram en reglering på venturin så att förutsättningarna förblir desamma vid mätning av olika temperaturer och lufttryck i en testrigg. Denna testrigg används för att utveckla produkten Varivent som används för att uppfylla högre miljökrav på förbränningsmotorer.I arbetet beskriver jag de olika krav som funnits för att bygga det nya systemet, dessa var ingångar, utgångar, mikroprocessor, reglering,kommunikation samt övriga krav. Jag diskuterar de svårigheter och möjligheter som är förknippade med kraven och tar även upp de komponenter jag använt samt deras egenskaper. Det svåraste momentet har varit PID-regulatorn som både varit en viktig och en svårlöslig del i konstruktionen av systemet.

Mätsystem för effektförluster i en högfrekvenstransformator

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

AIS i havets och tankens strömmar : En etnografisk studie av nautikers användning av transpondersystemet AIS

An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.
