The engine of JAS 39 Gripen, RM12, has recently been equipped with a new flameholder and a new engine inlet. This change has caused an increased noise level from the engine when the afterburner is in use. The noise level reaches its peak when the afterburner is partially used. The problem is thought to be unstable combustion in the regions around the flameholder. A solution to the problem has been proposed by Volvo Aero.

Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

Tidigare ombesörjde organisationen karriär och karriärutveckling för den anställde och karriärkontraktet byggde på livslånga anställningar. Det nya karriärkontraktet bygger istället på en så kallad proteisk karriär (Hall, 1996), vilket utmärks av att individen ser sig själv som ansvarig för och drivande av sin karriär, att egna värderingar får styra samt att psykologisk utveckling är främsta mål. Studiens frågeställning var att undersöka om personlighetsfaktorer i termer av self-efficacy, självkänsla, locus of control samt neuroticism kan predicera proteiska karriärattityder. I studien användes kvantitativ metod och en enkätundersökning genomfördes på studenter. Korrelationsberäkningar visade att samliga personlighetsfaktorer samt proteiska karriärattityder var korrelerade.

An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.

The aim of this thesis is to create an understanding about how and to what extent a Swedish expatriate manager needs to adapt his/her leadership in accordance with the culture of the host country. Thus shall different managers? perceptions of experienced management overseas be studied. To accomplish our aim, three different problems have been designed. These are as follows: In what way does the manager?s earlier experiences and knowledge about expatriation affect her or his leadership in a new cross-cultural context? How does the culture of the host country affect the expatriate manager?s leadership? How does the expatriate manager handle contradictory demands: that is differences in expectations from subordinates and the higher management? We have chosen to use an abductive approach in order to do a qualitative study and we have therefore conducted eight case studies to create a foundation for distinguishing patterns.The case studies are based on eight Swedish managers with experience from expatriation. The theoretical framework is structured upon three main themes including; knowledge and skills a global leader needs to possess, the relation between the leader and subordinates, and contradictory demands.

Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck.

Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.

In the latest years the Swedish armed forces have gone from an armed force with conscripts to voluntary men and women. When the basic training is voluntarily may the question be if the new men and women have the same approach to Desirable competences and pedagogy that is used by their officers during their training. Desirable competences are a part of the model transformational leadership and are divided into task related competence, management competence, social competence and capacitate to cope with stress.To deal with this problem I have used questionnaires from conscripts and a new questionnaire made on voluntary recruits.I have compared the results in a case study method and it shows a positive progress from the recruits view how the officers use examples from the transformational leadership. The study shows that recruits want officers to make demands, motivate and inspire them. The recruits want to know the goal with the education and they want the officers to make demands on them..

The aim of this master thesis is to investigate the ideas about functions that public libraries have in the local society. We have used the method idea analysis on four municipal library plans, to find out which ideas about library functions that frequented each plan, and what similarities and differences there were between the ideas about functions in each plan. As a theoretic base, we have used a theory about three dynamic spheres in modern society: the state market and civil society, and examined how these three spheres influence and control the library functions. We have extracted six different ideas about library functions: educational, social, economical, entertaining, serving and democratic functions. The most dominating ideas in this study are ideas that the public library should be an educating and formative institution.

The study has adopted an actor perspective and phenomenology as a philosophic and theoretical framework. The method used for data collection and analysis has also been influenced by phenomenology. Data consisted of five semi-structured interviews of a descriptive nature, and the goal of the analysis has been to articulate the general structure of the phenomenon. The results showed that the violence from patients is characterized by a professional commitment which includes always staying ahead and being able to help, protect and express a high level of emotional self-control.

To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.
