CFD simulering av en fyrtakts Otto motorcykel motor

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.

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.

Raymond Hains La France déchirée : En receptionshistorisk undersökning

This essay examines how the critical reception of French nouveaux réaliste-artist Raymond Hains 1961 exhibition La France déchirée has been articulated at two historically separate occasions.In her 2010 book Nouveau Réalisme, 1960?s France and the Neo-avant-garde, art historian Jill Carrick examines the fundamental impact the founder of nouveau réalisme ? French art critic and theorist Pierre Restany ? has had on the movement?s historical reception. According to Carrick Restanys writing established an interpretive framework that remained more or less intact for several decades. In addition to a closer analysis of the movement?s critical reception during the 1960s?, Carrick provides a set of new, alternative readings of a number of nouveaux réaliste artworks, which all originates from a position outside of Restanys interpretive framework.

Förbättringsarbete och avvikelsehantering för ökad tjänstekvalitet hos SCA Skog AB Jämtlands skogsförvaltning :

On a highly competitive market, quality is an important aspect to take into Account, both in terms of goods and services. The Swedish timber market is very competitive and to achieve long-term success focus on the customer, in this case private forest owners, is a prerequisite. SCA Skog AB Jämtlands forest management administration is dependent on the acquisition of timber from private forest owners to fulfil their mission to the supply of SCA's paper and sawmills in Sweden with raw material. To be able to develop the cooperation with private forest owners, the administration investigates their quality management by measuring the customer satisfaction index (CSI). The purpose of the study was to identify a practical and systematic method to handle deviations and suggestions for improvements to achieve a higher customer satisfaction.

Att gestalta en mördare : En studie om mediernas gestaltning av Thomas Quick

Media has a big actuating power over the public opinion. The image of reality that media choose to reproduce will affect the recipient view of reality. The case about Thomas Quick and its associated news coverage has been used as an example to illustrate the problematization regarding media imag-es and media framing attempt. The purpose of this essay was to illuminate how daily and evening newspapers works with various framing methods.The theoretical framework for this essay will discuss the media framing theory and its ramification attribute framing theory. This laid the foundation for the research question.

MOLNU : Att utveckla ett gemensamt gränssnitt

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations Account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

En jämförelse mellan att utföra en värdeflödesanalys av produktion respektive planering : Fallstudie på ABB ROBOTICS Västerås

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

Avgränsning av tillrinningsområden till grundvattenmagasin : vilken information ger berggrundens överyta?

Delineation of recharge areas for aquifers is performed in the groundwater mapping process at the Swedish geological survey, SGU. This work is time consuming and performed manually. It is therefore desirable to develop a more general and repeatable method for defining recharge areas for aquifers.The purpose of this study was to investigate two other possible methods to delineate recharge areas for aquifers. The first method was to examine the possibility of using the topography of the bedrock to define the recharge areas for aquifers. To enable this, a method for generating the topography of the bedrock was developed.

Demokratisk innovation eller ett spel för gallerierna? : En demokratiteoretisk utvärdering av Participatory Budgeting i en svensk kommun

The aim of this thesis is to explore the institutional design of Participatory Budgeting (PB) in Sweden and how the design may contribute to realize central democratic goods. The study records the different PB experiences in Sweden and focuses on one particular case, which is the only case that successfully qualifies as a genuine PB-process according to international standards and definitions. To examine this, the following questions are asked: which municipalities in Sweden have implemented Participatory Budgeting? How can the institutional design of Participatory Budgeting be described and to what extent does it enable the realization of central democratic goods? To what extent does the institutional design enable the realization of the democratic goods inclusion, popular control, considered judgment and transparency? To what extent does the institutional design enable the realization of the institutional goods of efficiency and transferability?The study is based on an institutional theory of democracy. The method used is a mixed method ideal type analysis that combines document analysis, surveys and interviews.

Bättre samarbete? : Interna relationer på ett växande företag

Med denna uppsats har forskaren haft som avsikt att presentera hur det fungerar när ett växande företag bedriver interna relationer, intern marknadsföring och samarbete mellan två utvalda avdelningar. Speciellt då dessa två avdelningar har ett litet beroende till varandra. Hur löser avdelningar emellan exempelvis eventuella problem som uppstår internt samt hur säkerställer man att avdelningarna är servicestödjande, motiverade och hjälpsamma gentemot varandra för att lyckas göra ett bra externt arbete.Det har visat sig att medarbetarna på det växande företaget Projectplace värnar om varandra. De personliga relationerna anses vara goda precis som de arbetsrelaterade relationerna. Flera teorier som forskaren valt ut för denna uppsats har visat sig överens stämma med det empiriska resultatet, vilket ytterligare stärker studiens reliabilitet.
