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.
Frihetens bakgård en litteratursociologisk studie om självets identitetsvåndor i det senmoderna samhället
This Masters thesis is analysing four Swedish novels written by first time authors published between 1993-2002. The purpose is to make the fictitious main characters illustrate what conditions and obstacles there can be for the individual of today to create a self-identity. Anthony Giddens ideas about the self in the late modern society are used as a theoretical framework. In the core of Giddens theory is the concept of reflexitivity which means that the self must be constructed in a continuous fashion because the overall conditions in society are subject to constant change. The questions posed in this study are dependable on Giddens in general and the concept of reflexivity in particular.
Genus och vetenskaplig kommunikation: en bibliometrisk studie av amerikansk biblioteksforskning
The purpose of this paper is to examine how the relationship between the socially constructed genders is manifested in American library science. To visualize gender, bibliometric analyses of peer reviewed articles published in three core journals of library science between 1980 and 2000 inclusive, are performed. The three journals are: College and Research Libraries, Journal of Academic Librarianship and Library Quarterly. Questions: 1. Does gender affect the publishing process regarding the distribution of female and male authors? 2.
Social ekonomi: Staten och det civila samhällets betydelse utifrån ett rättighetsperspektiv
The increasing significance of social economy as a concept is linked to general global processes such as the crisis of the welfare state, neoliberal globalization, anti-bureaucracy tendencies and decentralization, but also to a growing political interest in human rights and social development. In Sweden the idea of the social economy generates wide support within civil society as well as within the government and across party political boundaries. Furthermore, what is problematic in this context is the fact that the discussions on the subject tend to be relatively uncritical and often it seems as if though the expansion itself is the main objective. The emphasis on cooperation and the third sector in terms of welfare production implies a set of risks in relation to state responsibility, democracy and the autonomy of civil society. This paper aims to explore those risks and how they can be dealt with within the Swedish context..
Övervakningssystem för båtelektronik
Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
Mediadatabas med webbgränssnitt för hembygdsförening
Throughout the years the Swedish local history societies have collected a large quantity of material, consisting of photos, documents and items, among others. As the society has become more computerized, the need has increased for these collections to become digitalized. This is a way to make their media more easily accessible to the general public, but also to easily be able to archive and preserve for example photos and videos electronically.This thesis concerns itself with the work we have done for the local history society of Nyed in Molkom. The task set before us consisted of creating both a website for the society, and a reliable database from witch the website draws its information. This project allows anyone with administrator privileges to upload new files and any additional information.
Hur företag och organisationer kan attrahera innovationsmöjligheter : Ett uppdrag från Munktell Science Park
Syftet med detta examensarbete var att ta fram en modell för att attrahera innovationsmöjligheter till Munktell Science Park i Eskilstuna. Detta gjorde författarna genom att från befintliga teorier deducera fram en hypotetisk modell. Modellen används inte för att skapa innovationer utan för att hitta komplexa problem. Det är lösningarna på de komplexa problemen som i sin tur kan vara innovationerna. Därför har vi kallat de komplexa problemen för innovationsmöjligheter. .
Spelet mellan Trollhättan och Rüsselsheim. En fallstudie om globaliseringens påverkan på fackföreningar.
AbstractGlobalisation has lead to changes on many levels of our society; -industrial, technological, and corporate to name a few. This is an ongoing process which affects the society we live in today. The process is affecting the working-conditions for everyone through the changes of the relations on the working market. The unions have enjoyed a very special role in Sweden for a long time, but that role is now affected by these changes. The relationship between state and unions is changing, and the unions? influence in politics is decreasing.
Folkbibliotekens webbplatsers grafiska användargränssnitt Kvalitativa intervjuer med webbansvariga
The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.
Minimizing acts of violence through telephone-linked care: an
automated telephone system for outpatients in forensic
psychiatric care
Achievements within the fields of computer- and telecommunication technology have led to a revolution when it comes to managing information. These achievements have made it possible to offer new services in healthcare, especially in telemedicine. New technology has become a complement to traditional care, thus partly compensating for insufficient time and resources. Telephone Linked Care (TLC) is a telecommunication technology that enables automated dialog counselling and monitoring of patients in their homes. During the last two decades numerous randomized controlled studies with TLC have demonstrated improvement among outpatients with chronic and health behaviour disorders.
Chinese Remainder Theorem
Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.
Privacy Policy - Att skapa förtroende för en uppkopplad värld
Förtroende har sitt ursprung i trygghet och säkerhet. För att lämna ifrån sig
personlig information krävs att man känner förtroende och således även trygghet
och säkerhet. Tillgång till personlig information är en viktig konkurrensfördel
för ett företag. Samtidigt utgör den personliga informationen ett problem
eftersom många kunder känner en oro att lämna ifrån sig denna. Oron beror på
osäkerhet om vad som kan hända med den information man lämnar, denna oro kan i
sin tur leda till brist på förtroende.
Trender inom Business Intelligence
Business Intelligence har under de senaste åren vuxit starkare fram och
innefattar nu en hel yrkesroll i gränslandet mellan teknik och företagsekonomi.
Detta syns framförallt inom det företagsekonomiska området och särskilt inom
ekonomistyrningen. Denna uppsats försöker besvara frågorna ?Hur har utveckling
upp till idag av Business Intelligence sett ut?? och ?Vilka trender finns idag
inom Business Intelligence ur ett företagsekonomiskt perspektiv??. Uppsatsen
behandlar inte något specifikt verktyg eller systemleverantör utan har som
utgångspunkt att undersöka trender inom floran av systemverktyg utan att för
den sakens skull gå in på någon specifik lösning.
Business Intelligence historia summeras upp utifrån 60-talet fram till idag och
ett antal trender presenteras i punktform.

Background One of the main demands on Swedish and global health care in general is to meet the patient?s need for safety. By general health care law this also comprises district nurses? field of responsibility. Although there are numerous studies describing the concept of safety and its different shapes, no research could be found exploring how safety is, or supposed to be, mediated by district nurses? in a Swedish context.
Resor i 1800-talets Japan : En analys av två svenska reseskildringar i Japan under Meijieran
This thesis deals with the characterization of Japan and Japanese people by Swedish travelers during the Meiji period. It seeks to answer what aspects of Japanese people two Swedish travelers chose to highlight, and how these aspects were presented in their travelogues. This thesis also has a second aim. By applying Edward Said?s theory of orientalism, it wants to answer if Swedish travelogues were influenced by western 19th century ideas of colonialism and imperialism.
