System 348 - Rekombinator : Analys av reglerproblematik vid O2

In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.

Karlshamn-Wislanda Jernväg : Maktelit och nätverk i Karlshamns stad vid banans tillblivelse 1855-1874

The aim of this essay was to describe the power elite of the Swedish town Karlshamn, and its influences on the local political process before the realization of the narrow-gauge railway Karlshamn-Wislanda-Jernväg. During the mid 19th century, a revolutionary period began in the Swedish pre-industrial epoch. The political and institutional regulatory frameworks were disassembled and restructured, away from protectionism and centrally controlled administration, for the benefit of free trade, local self-government and liberalism. The changes were carried through during times marked by a drastic increasing native population and upcoming demands for adjustments to meet the growth of the industrial-, trade- and labour markets. An essential industrial development factor was the building of the national railway network, which started after some important decisions in the Swedish Riksdag during the 1850´s.

Gentrifieringsprocessen : Omvandlingen av nedgångna till attraktiva stadsdelar

Title: The process of gentrification ?the transformation of declined neighbourhoods into attractive ones Gentrification = ?A social process of change where people with high socioeconomic status move into neighbourhoods which traditionally has been dominated by people from the lower classes or from ethnical minorities.? (Nationalencyklopedin 2010).In many cities around the world, disinvested neighbourhoods become the place to be, where everything happens. This usually occurs when different social groups, such as bohemians, homosexuals and artists, move into a declined and disinvested neighbourhood. After a while, people from the middleclass move in to the area due to its increased attractiveness, and start to renovate their properties. This usually leads to higher rents, which force some of the original inhabitants to leave the neighbourhood.

Boken som aldrig tar slut En undersökning om urval och inköp av kulturtidskrifter på folkbibliotek.

The purpose of this Masters Thesis is to explore the process of selection that librarians face when selecting and acquiring cultural magazines to public libraries. The methods used are qualitative interviews and literary studies. A brief review is given of acquisition policies at public libraries and of cultural magazines and the important role they play in public libraries. Five interviews have been made at five public libraries to find out what factors affect the process of selection when it comes to cultural magazines. Two theories are used as a basis for the analysis of the result of the interviews and literary studies.

Incitament för fastighetsägare att omvandla bruna kontorsfastigheter till gröna - När och varför de väljer att investera

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Test och verifiering av en ny inkapslingsmetod för SiC BJT och MOSFET

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

Optimering av indunstningsprocess

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

Konstbiennalens Marknadskommunikation -Hur tre nordiska samtidskonstevenemang kommunicerar med sina viktigaste målgrupper

Introduction: Mental illness is a public health issue which 20-40 per cent of the inhabitantsin Sweden suffer from. Many factors can lead to mental illness and because of that it isimportant that different organisations and professions collaborate in prevention and healthpromotion work. To develop the collaborative process by noticing difficulties and successes,documenting, follow-up and evaluation is of great importance. Aim: The aim of this literaturereview is to investigate which methods are used for evaluation of health promoting anddisease preventive collaborative projects, which focuses on mental health directly orindirectly, and find out what results these projects has revealed. Method: Literature reviewwith descriptive design.

Verksamhetsstyrning i grundskolan - En väg till goda förutsättningar för inlärning

This study investigates how performance management in primary schools can facilitate learning, relating to theories of efficient schools. This is done through a qualitative study of the performance management systems in two public primary schools in Sweden. The schools selected were similar in all major aspects, except pupil grades, where there was a clear difference between the schools. The analysis revealed differences in how the schools handled the process of management by objectives, the professional development of teachers as well as routines, rules, and policies. We conclude that having a rooted process for management by objectives, professional development of teachers, and clearly formalized values, gives a school a good foundation to support a pupil's learning and development..

Ändringarna i expropriationslagens ersättningsbestämmelser : Har lagändringarna lett till några effekter för Trafikverket?

In December 2005 the government ordered a group to investigate the compensation law of expropriation. The purpose was to change the law so that it would reflect today?s conditions of expropriation.  The result of the investigation was that some changes were made in the law of expropriation. The aim of the changes was to strengthen the ownership of properties. Following changes was made in august 2010; the deduction of tolerance was rescinded as well as the rule of presumption and a new rule was added saying that the market value/decrease in market value should be multiplied with 25 percent when the compensation was calculated. The aim of this thesis is to investigate how Trafikverket has experienced these changes from 2010.

Europa - en plats eller en idé? : En diskursanalys av den europeiska identitetens konstruktion

Today Europe is faced with an identity crisis concerning its borders. Turkey stands at the threshold for an EU-membership while the EU-Commission is trying to formulate what constitutes a European identity. This identity seeking process will determine the future not only for Turkey, but also for immigrants now living in Europe.In this thesis a discourse analysis, underpinned by socialconstructionist theory, is conducted to explore how the European identity has been constructed throughout history up until today. A starting point is that identity always is defined through a dialectical relationship to "otherness". Therefore the analysis is focused not only on what a European identity consists of but also what and who it excludes.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Den dödliga mobiltelefonen

The purpose of this study was to highlight LGBT asylum-seekers experiences of expressing their sexual identity or gender identity in the country of origin and in the asylum process in Sweden. By interviewing people who got permanent residence in Sweden because of gender or sexual orientation in Utlänningslagen (2005:716) we have been able to explore their own experiences from expressing themselves. This study analyse these experiences from a social psychological perspective, from this analysis we aimed to obtain a deeper understanding of how the experiences from the country of origin affects on the experiences in the asylum process. This study shows that LGBT asylum-seekers often is facing negative reactions from the environment in the country of origin, these reactions can limit their possibilities to express their sexual identity or gender identity in the asylum process in Sweden. The negative reactions they experience in the country of origin have contributed to that many LGBT people internalize feelings of fear to express themselves, feelings that often stays when they come to Sweden to seek asylum.
