Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Det (o)synliga k?net i ledarskap - En intervjustudie om medarbetares uppfattningar om mellanchefers ledarskap inom finanssektorn

The purpose of this study is to investigate how employees in the financial sector perceive the leadership behaviors of middle managers, and if these perceptions differ depending on the manager's gender and if so, in what way. The study is based on a social constructivist perspective and theories of gendered organizational structures. It is based on 15 semi-structured interviews with employees who have either female or male middle managers from different companies in the Swedish financial sector. The results show that gender often acts as a framework for how leadership is evaluated and understood. Female middle managers are frequently associated with relationship-oriented qualities.

Förbättring av hanteringen vid utrikesfrakter på ITAB Shop Concept AB Jönköping

Our purpose with this report is to create a structural basis over how to improve handling with international freight at ITAB Shop Concept (further mentioned as ITAB). We have through interviews with employees at ITAB and observations identified problems that have caused difficulties at handling with international freight, from the time when an order is placed to when it?s delivered to the customer. We have also interviewed shipping companies.We have in the theory chapter written about shipping conditions for international freight and a main part of our theory is about NSAB 2000, which describes the obligations and rights shippers and consignee has.In order to improve the efficiency ITAB has to be aware of the problems in the company and try to solve them.The problems we have identified are described in the result chapter. One of the problems is that employees at the warehouse don?t know when gods is supposed to be shipped.

Simulation driven design : An iterative approach for mechanical engineerswith focus on mesh, quality and convergence

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

Hur eller Varför? : Kunskap i sociokulturellt eller existentialistiskt perspektiv? En kritisk betraktelse

This essay set out to propose a problematic interpretation of the socio-cultural perspective on learning. Its purpose is to show how the socio-cultural perspective on learning defines the concept of knowledge in an incomplete way. The aim becomes then that of giving a more comprehensive description of this concept, and, to this end, to construct a new, broader pedagogic discourse. The investigation starts with a deconstructive analysis of Roger Säljö?s socio-cultural text in order to point out the incompleteness of the concept of knowledge.

Den kommunala folkhälsosamordnaren söker sin arbetsroll

Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.

"Majoriteten av de psykiskt sjuka tar ju inte livet av sig" : Den sociala integrationens betydelse för självmord

Varje år begår ungefär 1100 personer självmord i Sverige, fortfarande finns det många obesvarade frågor om hur självmord kan förhindras. Syftet med denna studie är att undersöka om graden av social integration i ett samhälle kan förklara de skillnader i självmordstal som råder mellan Sveriges kommuner. Èmile Durkheims teori om egoistiska självmord har använts som teoretisk utgångspunkt och i tolkningen av studiens resultat. Studien bygger på data från statistikansvariga myndigheter samt data över självuppskattad hälsa från den nationella folkhälsoenkäten. För att analysera datan har vi använt oss av korrelationsanalyser och regressionsanalyser som vi gjort i statistikprogrammet SPSS.

Funktionshinderpolitiskt program : fallstudie om kommuns implementering av en FN-konvention

Author: Gabriella Agné and Helena LarssonTitle: Disability policy program ? a case study of a municipals implementation of UNs Convention on the Rights of Persons with Disabilities.Supervisor: Marianne Westring-NordhAssessor: Ulf DruggeThis study aims to examine how a small municipal in southern Sweden works with the implementation of the UN Convention on the Rights of Persons with Disabilities and examine the assistant officers knowledge about this work and user organizations inclusion and user involvement.The study operates from a qualitative approach based on the results of nine semi-structured interviews with local politicians, assistance officers and representatives from three different user organizations.The results show that the municipal has chosen to work with the implementation of the convention by creating policy programs for their departments through dialogue with user organizations, and by mapping the accessibility to public places. The results also show that the assistant officers have been given no information regarding the convention or the policy programs from their employers and instead operate from national legislations and prepositions. The user organizations feel that they were initially included in the process, but that their impact has later been removed due to structural reorganization..

Lantbruksföretagets utveckling av ny verksamhet : en studie av fem lantbruksföretag

The structural rationalization of rural firms in Sweden has led to many new creative ways of developing companies. The agriculture sector is characterized by the need of capital in form of buildings, labor and inventory. The rationalization process has led to free capacity in rural firms when new technology make buildings and inventory not longer necessary for the production process. To get a better cost coverage this free capacity can be used to start-up new business areas that help the rural firm to growth.The study aims to identify factors that motives entrepreneurs in rural firms to develop new business areas. The purpose is also to analyze driving forces that lies behind development of rural firms and the forces that support or not support development in rural firms.The study is built upon five cases that all can be categorized as firms with different size and orientation.

Territoriell stigmatisering. En litteraturbaserad studie om möjligheten att använda begreppet ?territoriell stigmatisering? i förklaringsmodeller bakom ojämlikhet i hälsa.

Introduction: Public health is based on the determinants of health. They mutually influence each other. Structural factors and life conditions contribute to health inequality both within and between countries. Health inequality can be seen between different social groups, which can be the cause of differences in living conditions, health behavior and disease vulnerability. One of the consequences of this is segregation which means that certain groups live apart, where this distribution can be connected to economic resources and/or ethnicity.

Kvinnoföreningar - rörelser för kulturöverskridande möten och social inkludering

This is an interview based qualitative case study on two Women's Migrant Associations in Malmoe, which I interpret as being part of a women's movement, with characteristics of a new social movement. The aim of this study is to get a deeper understanding on how the collective identity is being constructed, in this women's movement where the membership is not based on an exclusive ethnic identity.I make a two dimensional analysis that departs from a social constructivist underpinning, including the theories Transversial Politics, Postcolonial feminism and New Social Movement Theory.First I analyze the construction of collective identity from the external social and cultural context, and get confirmed that the collective identity of the movement is based on a common experience of social exclusion and a plurality of actions that aims to fight the structural injustices based on gender and ethnic discrimination. Secondly I analyze how the collective identity is being constructed and maintained from the interactions between the members of the movement, from an understanding of Transversial Politics. My findings show that the members of the movement interact in a participatory democratic way which generally corresponds to Transversial Politics. According to Transversial Politics this can lead to a construction of an empowered inclusive collective identity for the members and as my empirical study confirms it also means possibilities for deconstruction of boundaries between social groups..

Evaluation of Capital Structure Arbitrage in the Equity-Credit Markets

Purpose: The purpose of this thesis is to test for the existence of Capital Structure Arbitrage oppertunities in the equity-credit markets. Methodology: The mispricing of Credit Default Swap contracts are calculated and used as input in an Equity-Credit market trading strategy. The returns are then evaluated with a modified Value-at-Risk simulation. Theoretical perspectives: A Merton-based structural model, CreditGrades, is used for credit pricing and a mispricing-convergence trading-strategy between the credit and equity markets is implemented. Empirical foundation: Daily quotes for the Credit Default Swap spread of 37 European firms were collected for a period of two years, as well as equity-prices for the same period and the previous two years, used for model calibration.
