PPC is a new combustion concept that combines high efficiency with low emissions. This thesis is based on experiments conducted with a heavy duty PPC engine that was ran on neat methanol. A fuel that might be a candidate for future engine propulsion in large scale. By varying the inlet pressure, the corresponding inlet temperatures were found for premixed combustion, i.e. combustion in HCCI mode.
This thesis investigates a possible extension to the Standard Model: the Chirally Symmetric Technicolor Model. The motivation is to explain the origin of the electroweak interaction scale by introducing a new interaction. The thesis is based on the two-flavour Technicolor model presented in ”Chiral-Symmetric Technicolor with Standard Model Higgs boson” by Pasechnik et. al. [1], and extends it to t

Companies selling industrial machines are seeing a shift where profits are moving from new sales, towards retrieving revenue throughout the whole customer life cycle. Instead of selling new machines, the companies in the industry need to look towards what is referred to as “the aftermarket”. The aftermarket is the part of the market where spare-parts and maintenance services are sold to existing c
Uppsatsen tar avstamp i SOM-insitutets mätning från 2014 som visade att en majoritet av de tillfrågade ansåg att svenska medier inte berättar sanningen om samhällsproblem kopplade till frågor som rör migration- och flyktingpolitik. Samtidigt som med misstroendet mot medierna breder ut sig fortsätter digitaliseringen av medielandskapet vilket leder till en allt mer diversifierad nyhetskonsumtion. DThis essay builds on a public opinion poll from 2014 indicating that a majority of the Swedish citizens believe that mainstream media are hiding “the truth” about social problems related to issues of migration and refugee policy. The outspread distrust of mainstream media takes place during a time of continuing digitalization of the media landscape, which has led to increasingly diversified news c
Pålitliga simuleringar av komponenters hållfasthet kräver att materialets egenskaper studeras ordentligt. Gummi med fyllmedel uppvisar olika egenskaper beroende på tillämpning. I denna studie undersöks möjligheten att använda förenklingar vid simulering av materialets egenskaper.The aim of this study was to examine if simplified linear analysis can be used to capture the complex and non-elastic behaviour that filled rubber exhibits. Linear analysis includes both linear elastic material models and a linear solving technique. The studied part in this thesis was a hose, connecting the air-inlet and turbo in a Scania truck engine. The studied material was a filled EPDM-rubber
Hur renoverar vi en 70-talsvilla så att dagens krav på energianvändning nås? Vad finns det för tänkbara åtgärder med detta i åtanke och med hänsyn till eventuella fuktproblem? Vad är våra rekommendationer efter denna studie för referenshuset samt för hus av liknande typ från 70-talet? Målet med studien är att ta fram förslag på en bättre konstruktion dels för referenshuset och dels för 70-talshus
Promoters of improved cook stove technologies (ICS) argue that the use of these technologies offers several benefits such as improved health, fuel saving, reduction in green house gases emissions among others. Many of the studies exploring the use of improved cook stoves reveal a strong pro-diffusion bias towards these benefits, and few studies have investigated the adoption and use of ICS from th
Israel, Jordan and the Palestinian Authority share scarce-water basins on which they rely. Official water agreements in the area have been seen to be insufficient and protection of the common waters is vital to ensure sustainable water use. Water gives a chance and challenge for cooperation, particularly as the geopolitical situation constitutes an obstacle. The aim of this study is to examine the
The purpose of this thesis is to investigate and analyze power relations between Muslim female and male employees, active in working together with gender issues in two Indonesian non governmental organizations in Java. The study analyzes power relations and gendered work among female and male employees in the daily work and aims to give a picture on both female and male experiences from working to
Samer är Sveriges ursprungsbefolkning och har därför vissa rättigheter knutna till detta, bland annat har de rätt till land och vatten för att kunna upprätthålla och utveckla sina traditioner och sin kultur, en del av detta är renskötseln, som kan innebära säsongsbundna flyttningar med renar ner till kustlandet. Rättigheterna grundas i att renskötsel bedrivits över lång tid och även om det int
The aim of this essay is to explore the discourse of institutional cultural policies on the promotion of reading, through a series of questions centring on power relations and ideology. The theory and method chosen for this investigation are that of Critical Discourse Analysis, mainly as developed by Norman Fairclough. As the ability to read and understand written texts is imperative to democracy
The purpose of this thesis has been to illustrate the performative aspects of the expressions created by the Swedish reception of Valerie Solanas’ Scum Manifesto, by focusing on Malin Arnell’s performance piece I didn’t do it for nothing. Arnell’s performance works as a connecting point on which Judith Butler's account of performativity and Louis Althusser's theory of interpellation has be
As one of the world’s largest donors, Sweden’s development cooperation has a vision to make a change that will lead to a better world. But how do we know that our aid assistance affects the world for the better? Measuring aid is a very well discussed subject and this paper aims to examine how much the Swedish aid politics focuses on measuring results, and if there are any positive or negative aspe
The primary aim of this thesis is to understand the structure of fashion week in contemporary Stockholm. Does it have a hierarchical or democratic structure? Which participants does the fashion week in Stockholm aim itself to and for what reasons? This encourages further questions concerning the institution of a fashion week and what impact it has for the individuals working in the field. To sum u
Den internationella militära insatsen i Afghanistan har sedan inledningen varit mycket debatterad världen över. Inte minst i Sverige då regeringen redan under det inledande året beslutade att ställa svensk militär personal till förfogande. Denna studie fokuseras till en svensk kontext och till språket i tre propositioner vilka uttrycker regeringens ståndpunkt gällande ett svenskt militärt bidrag t
