Utveckling av 22 : -en motkolvs HCCI motor

Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

Skiftarbetets potential i byggbranschen

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Hälsa och hälsorelaterat beteende : En undersökning av beteendets betydelse för den självskattade allmänna hälsan

An increasing number of health problems in the population and an uneven distribution of health between different groups in the society, have been identified as a problems and has therefore been put on the political agenda in Sweden. Thus, the purpose of this thesis is to estimate and discuss the significance an individual?s behaviour, in a number of areas, has on his/her level of health.The empirical material for this thesis is taken from a nationwide inquiry conducted in 2004,which was called ?Hälsa på lika villkor?? (Health on equal terms?) The material used consists of the answers and records from individuals living in the administrative district of Kronoberg. 9972 individuals were included in the sample and the answering frequency was 63,2%. To map and analyse the material, which was done mainly through crosstabs, chi-square tests and logistic regressions, the statistics software SPSS 11.5 was used.The parameter used to measure the health level is the individual?s own perception of his or her general health.

Kommunikation och samverkan mellan projektering, inköp och produktion (PIP) i ett byggprojekt. En utredning av en PIP-plan och ett förslag på en arbetsplan.

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

Bränslecellskonvertering av linfärjan Tora

Denna rapport består av information och data som har samlats in i syfte att kunna presentera en genomförbar konvertering av linfärjan Toras framdrivningssystem, som idag utgörs av dieselelektrisk drift, till bränslecellsdrift. Den bränslecell som behandlas i rapporten är PEMFC och är en bränslecellstyp som drivs av ren vätgas. Resultaten tjänar som en informationskälla för en potentiell konvertering och presenteras för Trafikverket, som ett alternativ i linje med Sveriges regerings mål att reducera mängden CO2 utsläpp på en nationell nivå. Informationen i rapporten har insamlats via mail- och telefonkontakt samt ett besök på Tora på plats i Stockholm. Ett genomförande av konverteringen är fullt möjligt men mer kostsamt än dieseldrift i dagsläget med avseende på höga bränsle- och inköpskostnader utav bränsleceller.

Vem attraheras av vad? - En studie vars syfte är att förstå hur olika konsumentgrupper skiljer sig i termer av attityder och preferenser gentemot CSR-kommunikation

Corporate social responsibility (CSR) does not have an explicit definition but instead entail a broad spectrum of various obligations that an organisation is responsible for. CSR has in recent years become a highly relevant and debatable topic as a consequence of the increased exposure of companies to society. Due to an augmented consumption from the general population, CSR is of great importance in companies' aspiration to create and maintain a solid relationship with costumers. Previous researches have described what areas of CSR are most relevant in terms of consumption. However, it can be suggested that these publications have failed to provide an indication of what type of costumers these various areas attract.

This survey investigates the roll of public service in Scandinavia in a new and changing media industry and how they should act to be important for their audience.

Re: Yarning

From a social perspective, I have been working on how to change current consumption patterns through a change in people's behavior and attitude towards their possessions. The concept is based on how we can value, care for, and preserve our belongings by using theories in the empathic design field. I have created a structure that allows people to become an active part of a creative process and create their own products. Through this commitment, an emotional relationship is built between the user and the product, and the product tends to gain a longer life. Based on a method to manufacture your own yarn by reusing old clothes, I want to provide the basic tools for an easy and playful way to build the knowledge needed to produce something useful..

IT-organisationer börjar ta större och större plats i bolags affärsverksamhet, och är idag även en av de största kostnadsposterna. I samband med detta ökar kraven på den IT som levereras där bland annat fler vill ha bättre insyn i vad som levereras och hur mycket leveransen kostar. Detta behov av insyn återfinns både hos IT-leverantören och hos deras kunder. Problem finns emellertid att göra IT mätbart i finansiella termer.  IT Financial Management (ITFM) är ännu i sin linda, men är en arbetsprocess som tar sig an denna problematik; Att kunna ge finansiell data på IT-tjänster. ITFM är en del av det vidare begreppet IT Service Management, vilket syftar till att beskriva hur IT som tjänst levereras på bästa sätt till en kund.

Biogasanvändning vid Käppalaförbundets Reningsverk: ? en värdering av miljöeffekter

This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.
