In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

This report is a result of a bachelor thesis at the school of Architecture and the Built environment (corresponding to 15 HP) and is written during spring 2012 at the Royal Institute of Technology (KTH) in Stockholm. The Bachelor's essay is based on the design and dimensioning of a house which is located at a predetermined site in Malmo, Sweden.The idea is to construct a house that is appropriate to use for an average Swedish family of four family members. The house is designed in a modern way with respect to ease of access and disabled facilities. The installation that have been considered are heating, ventilation, sanitation and electricity. Construction calculations and material selection are also discussed.Furthermore, a study about photovoltaic cells has been done.

Detta examensarbete har utförts på uppdrag av Koenigsegg Automotive AB, som utvecklar, tillverkar och säljer högpresterande sportbilar. Företaget erbjuder fälgar tillverkade helt i kolfiberkomposit, som ger betydande viktbesparingar i jämförelse med traditionella metallfälgar.Efter tillverkningen kräver fälgarna viss bearbetning vid anläggningsytan mellan fälg och däck. Syftet med examensarbetet har varit att undersöka möjligheten att utföra bearbetningen av fälgarna in-house i Ängelholm, och målet har varit att konstruera en maskin för detta ändamål.Projektet inleddes med en litteratursökning, där svårigheter och möjligheter gällande bearbetning av kolfiberkompositer undersöktes. Till följd av de undersökningar som gjordes, valdes bearbetningsmetoden svarvfräsning och ett antal konstuktionskoncept genererades. Genom ett antal utvärderingar utvecklades ett speciellt koncept vidare till ett komplett produktförslag.Produktförslaget är komplett med analyser, beräkningar samt tillverkningsunderlag, som ger uppdragsgivaren bättre insikt i sina möjligheter.

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

This report describes the planning and the accomplishment of the final diploma workat the study program Mechanical Engineering, Department of Engineering Sciences, Uppsala University. Two students carried out the diploma work at GE HealthcareHusbyborg in Uppsala.The aim of the diploma work was to develop and improve existing processequipment for 11C-radiochemistry in PET. The process equipment was to be dividedinto smaller independent modules to make it more flexible. Part of the existingprocess equipment is an oven that is supposed to perform a specific chemicalreaction. One of the main goals was to study and improve this oven.The work could be divided into three main phases: 1.Present concepts for one module, and interface between different modules.

Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global markets. The existing literature is fragmented and solely based on the experience of larger companies. We believe that SMEs are facing new and different challenges, and thus a new generic theoretical frame work is desirable.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

The purpose of this paper is to investigate and analyse the private researchers encounter with the Royal Library, national library of Sweden. The main focus is on answering the two questions: who is the private researcher and what is his/her impression of the Royal Library? These questions are answered from the vantage point of the following theoretical perspectives: library anxiety, Bourdieu, library architecture, gender studies and service management. The methods used are qualitative interviews, and textual analysis using the printout of these taped interviews along with notes and an earlier user study as material. The conclusions are that barriers with staff is the most frequent factor of library anxiety in the private researcher at the Royal Library, and mechanical barriers the least frequent.

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

Syftet med examensarbetet har varit att undersöka möjligheterna att utveckla, producera och lansera en ny universell laddare.

ROT är förkortning till ? Reparation, Ombyggnader och Tillbyggnader ? som ä avseddför skatteavdrag för vidtagna energibesparande åtgärder inom byggnadsektorn. Syftetmed det här examensarbetet är att undersöka olika slags besparingar med hänsyn tilldagens befintliga flerbostadshus omständigheter. Byggnadens energianvändning skullegenerellt kunna minskas genom att förbättra klimatskal som exempelvisbyggnadstekniska åtgärder och utnyttja nya installationstekniska åtgärder bl.a. som FTXventilation system eller värmepumpar.Med hjälp av IDA ICE energisimuleringsprogram ska två flerbostadshusmodeller byggas.Resultatet från energiberäkningen med IDA ska analyseras och jämföras medbostadshusets energistatus idag.

Syftet med studien var att undersöka sambanden mellan Dark Triad (de mörkapersonlighetsdragen Machiavellism, narcissism och psykopati), Sociosexuell orientering(beteende, attityd och lust till att medverka i tillfälliga sexuella relationer) samt Religiositet.En korrelationsanalys utfördes för att undersöka sambanden mellan variablerna och enmodererande multipel regressionsanalys (MMR) utfördes för att undersöka om religiositetmodererade effekten av Dark Triad på sociosexuell orientering. Deltagarna bestod avamerikaner (N =309) som svarade på en webbenkät via Amazon Mechanical Turk (MTurk)vilken innehöll Dark Triad Dirty Dozen (DTDD) och the Revised Sociosexual OrientationInventory (SOI-R), dessutom angav de religionstillhörighet/ingen religionstillhörighet.Dark Triad hade ett positivt samband med sociosexuell orientering, men inget sambandmed religiositet. Sociosexuell orientering hade ett negativt samband med religiositet.Religiositet modererade inte effekten av Dark Triad på sociosexuell orientering. Resultatenbekräftar delvis tidigare forskning. Trots att religiositet inte modererade effekten av DarkTriad på sociosexuell orientering, borde detta förhållande undersökas vidare eftersom ingentidigare forskning gjorts på området..
