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..

Denna rapport beskriver framtagning av modellen, verifiering av modellen och vilka framtida användningsområden modellen lämpar sig för.Simuleringsmodellen är uppbyggd av ett antal komponentmodeller. Komponentmodellerna innehåller formler för respektive komponent i hjulaxeln.
Target Costing i produktutvecklingsprocessen : En studie på Volvo Construction Equipment i Braås
Bakgrund: Produktutvecklingsprocessen har på senare tid kommit att ses som en strategisk aktivitet som är avgörande för företagets överlevnad eftersom produktens utförande och kostnader till stor del fastställs innan tillverkning påbörjas. ?Target Costing? har sitt ursprung från Toyota i Japan och är en metod för strategisk kostnadsstyrning som har vuxit fram för att tidigt styra kostnader. Metoden används för att integrera kostnadsstyrning i produktutvecklingsprocessen i samstämmighet med kundkrav och företagets egna vinstkrav.Syfte: Syftet med studien är att beskriva och analysera hur ?Target Costing? används i produktutvecklingsprocessen på Volvo Construction Equipment i Braås för att ge kunskap till nya potentiella användare.
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.
Vidareutveckling och utvärdering av operatörsplatser på svenska stridsfartyg
The ability to handle potentially dangerous and hostile situations on a military vesselrequires that the equipment works effectively with the personnel that use it. It is importantthat this equipment can be used by different people. An operator on a military vesselshall be able to handle information about hostile threats, navigation and the steering ofunmanned vehicles. A operator console should therefore be constructed in such a waythat the operator can handle a large flow of information. And the information given bythe technical system should be displayed correctly to facilitate the operators ability tohandle and interpret the information correctly, in order for the operator to make thecorrect decision at any given moment.
Uppstart av Totalt Produktivt Underhåll på Tour & Andersson AB
In order to continue to be competitive in the current industrial climate, producers must increase efficiency at their plants. Several Swedish companies choose to utilise the principles of Lean production. Tour & Andersson AB (TA) has elected to create their own model using Toyota?s productions system which has been named TAPS (Tour & Andersson Production System). Following two years of working with TAPS the company has decided to introduce Total Productive Maintenance (TPM).
Most of the work carried out in the maintenance department today is in form of repairs to already faulty equipment.
Mikrolitografi för rastrerade Gobos
Beacon AB has been producing Gobos for some time. A Gobo is a small round sheet used in projectors almost like a slide. It is used mostly in the commercial and entertainment business. Today these Gobos are created by using a film (also called mask). A digital exposure machine called LIOS has been developed to make it possible to create Gobos using direct exposure.
Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar
The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.
Induktiv provning av ferritiskt rostfritt stå
The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

Prognostisering av utrustningar på Volvo Wheel Loaders
Volvo in Arvika produces wheel loaders, and the production is based on forecasts. When a machine is ordered, the customer can choose what type of equipment he or she wants, and these equipments are also made forecasts on. This is made by giving each equipment an estimated procentual usage that shows how many of the machines that will use this option. Today two people are working with the forecasts, planer A in Eskilstuna and planer B in Arvika. Planer A makes a forecast based on the historical outcome and planer B then makes adjustments of this based on how many options that are ordered.
Konstruktion av steghållare till brandbilar
High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.
