To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

This thesis deals with an iterative user-centered IT-development project in a bank setting. The aim is to present a solution for deployment of future Internet banking for small businesses. The project features a design of IT-related concepts and ideas with a strong emphasis on scenario-based design and the usage of patterns as a documentation tool.The project plan featured an iterative framework and was carried out by a group of designers in collaboration with a reference group representing the future users of the system. This group consisted of company managers and bank employees, all from the small town of Åtvidaberg in Sweden.The method used in the development process was Scrum. A total of three sprints were completed with user meetings at the end of every sprint.

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.

Det här arbetet består av en djupgående fallstudie av FN:s roll i Kambodjas demokratiseringsprocess, där fokus ligger på den stora interventionen som skedde i början av 1990-talet. Arbetet är till stor del av deskriptiv karaktär där vi försöker reda ut händelseförloppen i Kambodja efter Röda Khmerernas fall. Vår utvärdering av FN:s insats är att den har haft en stor påverkan på landet, men att man inte till fullo lyckades uppnå den långsiktiga demokratin som var FN:s intention. En förklaring till varför man inte lyckades skapa demokrati i ett längre perspektiv, kan förklaras utifrån de organisatoriska brister som fanns, men även FN:s rädsla att bedriva det ledarskap man ålagts genom fredsavtalen. Vi kommer att utgå från ett koncept om ?peace-maintenance?, som innebär ett helhetsperspektiv, där vi konstaterar att FN hade kunnat förbättra vissa punkter för att åstadkomma ett bättre resultat..

Abstract The purpose of this study is to identify how Swedish clothing companies strategically communicate CSR ? the issue being that CSR communication is frequently scrutinized and criticized. This is examined using semi-structured interviews with six company representatives. The result is presented thematically, dealing with (1) conditions for CSR and CSR communication, (2) how to manage the issue with criticism and (3) which communication strategies companies use. Following conclusions are drawn: the companies can be divided into Mirvis and Googins phases integrated or engaged/innovative, with conditions characterizing these phases.

AbstractIn my study I have investigated how a constructed outdoor green environment can beused, managed and how it works. The study also investigates the concept of socialsustainability, where, for example, civil dialogue is a method to promote this. Thisinvestigation mainly gives account for the inhabitants viewpoint but also a gardenersperspective. The study focuses on the planning process of the study object, what theoutcome has been and how the users of the green environment, think about the result. Inthe process there has been a strong concern of involving the residents and others usingthe area.

Integration is a concept that is very topical in today's multicultural-cultural society. Integration means that everyone should have the same rights, opportunities and obligations to society, regardless of extraction. What counteract integration is segregation, which implies a distinction between different groups and where there exist an inequality between them. Segregation is widespread in Sweden today and the exclusion that it creates needs to be broken. The aim of this paper is to examine if it is possible to promote integra-tion through physical planning.

This thesis focuses on the testing activities at the stages of development and change regardingintegration brokers. The study aimed to examine the overall challenges that exist regarding thetesting activities within this context, and the thoughts towards the development method testdrivendevelopment (TDD). TDD emphasizes high level of test coverage and where the testprocess is well integrated with the development process. To seek answers to our question weapplied qualitative interviews with companies and respondents to try to understand the globalchallenges that are related to this work and processes. The main conclusions presented in thisstudy is that the overall challenges are involving and educating project participants in the testingprocess activities and the contributory effect test have on the end product.

Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..

Övervikt och fetma anses vara ett globalt folkhälsoproblem, vars omfattning tycks ha ökat de senaste årtiondena. Förklaringen till det anses ofta vara en västerländsk livsstil bestående av kaloririk kost och bristande fysisk aktivitet. Att lyckas med en livsstilsförändring tycks därmed viktigt, men svårt. Syftet med studien var att identifiera framgångsfaktorer som bidragit till initierande och vidmakthållande av en livsstilsförändring. Enskilda intervjuer, med tre kvinnor och tre män, genomfördes därför med individer som vidmakthållit en livsstilsförändring i minst två år.

The foundation of our study is five strategically selected printed advertisements which all contains signs that refer to digital medias. Through a quality content analysis, we are studying how advertisers may use a room with extended communication too enlarge the space given in a printed advertisement. The potential in these rooms are proposing a social connection and a flexible interaction by providing content that is not possible to create in a printed advertisement. The form of communication is changing and there is a two-way communication created in an obvious way. The different kinds of roles in the communication process are here partially integrated with each other.

Informationsteknologins och revisionens utveckling bidrog till att det under 1980- och 1990-talen växte fram ett behov av att fastställa vad intern kontroll innebär. Internal Control ? Integrated Framework, lanserat år 1992 av The Committee of Sponsoring Organizations of the Treadway Commission, är det internationellt mest erkända ramverket för utformning av intern kontroll. Syftet med ramverket var att säkerställa en förbättrad bolagsstyrning efter de företagsskandaler och förtroendekriser som skakat företagsvärlden under de senaste decennierna. Svensk kod för bolagsstyrning kom i slutet av år 2004 och hade som syfte att ytterligare förbättra styrningen för svenska företag.

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.
