This thesis investigates the dynamics of the relationship between a leader and the followers within a chosen organization. The research on leadership has generally been focused on the leader, and consequently treating the followers like passive subordinates. We pursue a more multidimensional view of the subject, meaning that leadership descends from an interaction between leaders and followers, which makes it relevant to study the dynamics of the relationship from both perspectives. We chose to do a qualitative case study on a middle- and preschool which has won a price for being an ideal place to work at. This price peaked our interest to investigate why the relationships are highly functional in this particular organization.

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.

To publish research articles by the means of open access is to provide them for free to the reader. An increasing number of universities around the world have begun to institute open access policies regarding their researchers academic output, requiring them to primarily publish in open access journals and / or archive their pre- or post- prints in institutional archives.The aim of this this thesis is to explore how the adoption of the open access policy at the Swedish Universi- ty of Agricultural Sciences in 2008 has affected how their researchers publish and if this has had any effect on how their academic output are cited and distributed online. To reach this goal a combination of bibliometric and altmetric methods were used as well as cross-referencing between Scopus, Altmetric.com, Google Scholar and the SHERPA/RoMEO database.The results points towards a mostly open access positive trend with an increase in articles published in jour- nals that allow archiving of both pre- and post-prints. There also seems to be a correlation between these journals and which kind of articles gets the most mentions in social media..

This phenomenological study explores the mental health problems of asylum- seeking children in Sweden and highlights possible ways of meeting their needs. Open interviews with 13 clinically experienced psychologists were conducted.The results of the analysis suggest that experiences of trauma and separation, the child's developmental level, parental functioning and family dynamics contribute to the mental health problems of asylum- seeking children. When meeting these children the psychologists continuously face ethical dilemmas since the asylum-seeking process seems to aggravate the problems as well as complicate the use of traditional interventions. Promoting structure and activity, normalizing symptoms, educating about trauma and crisis, sharing and accepting anxieties and sometimes thoroughly working through traumatic experiences are treatment strategies found clinically useful. Systematic follow-up studies are needed to decide the effects of these interventions..

The purpose of this Master Thesis was to study the reader in the informal reading group. To fulfil our purpose we have used the following questions: how did the reader become a reader and what does her reading look like, why do people choose to participate in a reading group, how may the group influence the individual member in her reading and interpretation of a book, does the reading group have a therapeutic function, how does the informant find the group dynamics and different roles in the reading group, and finally how does the informant experience the discussion in the reading group. We have used two studies about reading groups, one by Elizabeth Long and one by Jenny Hartley. Our theory is divided into reading and group psychology. We have interviewed seven women belonging to different reading groups.

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Through extensive research it has shown that today?s sail boat owners are very frustrated concerning the limited choice of engine alternatives offered by today?s market. Besides rising fuel-costs, environmental awareness is very important in today?s society. Hence it is vital to find alternative environmental-friendly motors and replace combustion-engines. Zilent Ocean is an extensive project within Development engineering program at Halmstad University.

This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of  crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

The problems caused by the current engine casing in aluminum for Volvo Buses Corp. are the mainfoundation for this degree project. Lack of maintenance combined with a construction poorlyadjusted for assembly has resulted in the fact that the engine casings rarely get reassembled whenthe service is completed.The degree project has mainly been following ?Olssons.
