Utveckling av en Multi-Zonsmodell för NOx Bildning i Diesel Motorer

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Att skapa en digital samling: En kvalitativ studie kring de socialpolitiska faktorerna som rör KB:s val att inte använda DIGSAM i sin digitala verksamhet

This thesis purpose is to investigate the sociopolitical factors and causes that led to why KB chose not to use the criteria and guidelines for their digitization activities are described in DIGSAM. To do this I focused on three research questions;- What factors (internal / external) led to the decision not to use the criteria guidelines for digitization, which is described in the policy document DIGSAM and what arguments and opinions formed the basis for the decision.- What is the Library's digitization activities, the factors, criteria and guidelines governing activity in the current situation? - Will KB's choice not to use DIGSAM as a whole in their digitization activities affect national library's role as a beacon for the Swedish libraries digital work? In what way and why? In order to answer these questions I interviewed three of KB:s librarians who had extensive knowledge of digitization and DIGSAM. I chose to also use a pilotstudy that was conducted at KB in the of spring 2010. The idea was to use this material as a basis to build on.As a theoretical framework, I chose to use a socio-political theory of Ingrid Mason.

Visualisering av FRAM

The Functional Resonance Accident Model is a method developed to analyze complex systems for the purpose of accident prevention. In FRAM-analysis a visualization of the complex system is created as an aid for identifying points of interaction in the system where the risk of accidents is high, and to determine where preventive measures are to be placed. FRAM Visualizer is a computer program developed as a tool for creating such visualizations.Many usability problems have been identified in FRAM visualizations created both manually according to established method and by using the FRAM Visualizer software. The purpose of this paper is to give a basis for how FRAM visualizations can be improved in accordance with usability criteria for use in future qualitative studies.The author suggests alterations to the FRAM visualization to resolve usability issues identified in previous articles and to achieve usability goals derived from visual communication theory. The design process is guided by established design principles.

Läsförståelse med stöd av Läsfixarna och Leselos : En jämförelse mellan en svensk och norsk arbetsmodell för ökad läsförståelse

The purpose of this study is to understand how the school manages to question norms, and in doing so might prevent its students from being subjected to discrimination and other degrading treatment. This has been done with a focus on how gender related norms are represented, reproduced and questioned in children?s fictional literature.

The survey was conducted on primary school teachers with the intent to collect information related to their thoughts when choosing books to use in their classrooms, and also to source commonly used fiction.

Finansiella analytikers användning av redovisningsrapporter : En studie av möjliga konsekvenser med ett utökat informationsinnehåll

The accounting of today results in reports that are valued according to one kind of value.There are advocates who recommend that the accounting should be expanded by one orseveral columns, which would enable that other methods of valuation could be used. In thisessay we examine how the ?multi column reporting? can alter the outcome of a financialanalysts? valuation procedure.In this essay we used existing theories about the financial analysts? usage of information toreach the lack of information we found and which we aim to erase whit this essay. To do thiswe studied decision theories and theories regarding information processing, and by interviewswith three financial analysts. After we collected the information needed for the analyses, wethen also compared the results of the interviews with related theories.The theories about decision in this essay concern whether a decision is based on rationality,bounded rationality or irrationality.

Urval vid digitalisering av affischer på Kungl. biblioteket

This thesis presents a study aiming to identify the selection criteria for the digitization of posters at the National Library of Sweden (Kungl. biblioteket). The theory is that cultural heritage institutions are empowered to decide how our cultural heritage is presented as they select what items (or, as in this study, posters) will be digitized. The poster is studied as it is an interesting media form which historically was an important means of communication. The poster can represent and reflect historical events and opinions in society.

Smarta Hus : Nya behov och lösningar med participativ design

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems.

Sociala företag en av flera aktörer i det sociala välfärdsarbetets tjänst

Social enterprises make up one of the groups of participants that provide welfare services financed by public funding. The object of this study is to describe and analyze from a theoretical point of view which conditions, in what fields, by which division of responsibility and finally through what decisions these social enterprises are allocated a place in the market for social welfare services. The company that has been the object of study offers services in the field of social welfare and in employment. In the study a triangulation of qualitative methods has been used: studies of literature on the subject, recurrent interviews and observations and also reviews of documents. The results have been analyzed from theories on the space available on the market for social services, on social economy and on social capital in the form of strong, weak and bridging bonds.

Nationalistiska och främlingsfientliga? -En diskursanalys av högerpopulistiska partier i Skandinavien

The focus of this study is the ways in which the discourses of the three largest right-wing populist parties in Scandinavia ?
