The aim of this thesis was to develop a model for flame propagation, to implement in a zero-dimensional engine simulation tool (DARS 0d-SRM) which previously only used fitted Wiebe-functions to describe the flame propagation. The idea was to create a model which could replace or complement the Wiebe function, but with predictive capabilities, avoiding the need to perform curve-fitting when certain

Tandhälsobeteende styrs till viss del av attityder. Därför undersöktes attityder genom en enkätundersökning med 218 medverkande (studenter n=159, seniorer n 58) med ett bekvämlighetsurval. Svarsfrekvens 76,6%. Arbetet kartlägger existerande attityder till tandsjukdomar och tandhälsa, samt behandlar hur viktig tandhälsa uppfattas, jämfört med hur viktig allmänhälsa. Tandhälsa och allmänhälsa ansågs

The main aim of this study was to investigate whether Cognitive Behaviour Therapy (CBT) methods could be used to change implicit attitudes towards bullying.

Background: With todays’ requirement of shorter product life cycles and faster time-to-market, producing companies experience an increased demand for faster transports in the supply chain. This puts pressure on freight forwarders to offer their customers a timely and reliable transport service at a reasonable price. Another challenge for the freight forwarders in Sweden is to provide such services

Product development in the automotive industry is characterized by a high demand on short lead times and efficient use of resources. This is no different for Volvo Bus Corporation, the second largest manufacturer of buses and bus chassis in the world, whose global product development organization is under pressure to find new ways to meet an increased amount of projects along with requirements on

The aim of this explorative study is to gain knowledge about the question of identities formations in different socio-cultural contexts. This is done by looking at the specific case of the Oromo people living in a larger community (Minneapolis, USA) as compared to living in a smaller group (Stockholm, Sweden). The case of the Oromo people is investigated in light of past historical, political, soc

This paper first measures the energy efficiency of 28 provinces from 2001-2009 with DEA model. Different from previous studies that include labor, capital and energy consumption as input indicators, GDP as the only desirable output, this paper also models the undesirable output by introducing environmental pollution index. The result shows that eastern area has highest energy efficiency while the

Using a sample of all German CDAX stocks between 1995 and 2011, this article compares returns of a momentum strategy based on Jegadeesh and Titman (1993) with a strategy that is based on a stock’s closeness to its 52 week high. The paper finds an outperformance of the 52 week high strategy in favor of the momentum strategy on the level of raw and risk adjusted returns. As in some cases abnormal re

I den här uppsatsen analyseras hur översättaren av Patti Smiths bok Just kids har översatt bildspråket i textens tre mest framträdande bildspråksdomäner som har en stark koppling till textens tematik. Bildspråksdomänerna är: krig, natur och religion. I uppsatsen undersöks även om kompensation har använts för att undvika att eventuella bildspråksförluster försvinner helt i översättningen. I uppsats

This thesis offers a study on how well the standard GARCH(1,1) model, the GJR-GARCH(1,1) model and the QGARCH(1,1) model, were able to model (in-sample) and forecast (out-of-sample) the volatility of copper spot price returns in four equally large subsamples within the period July 21, 1993 to 22 Mars, 2012. The results shows that the GARCH models' ability to model the conditional variance (in-

The aim of this study was to examine how a budget-led practice affects middle managers with budget responsibility in the Swedish public social services to do their jobs.

Social Work Education today places great importance to convey values such as respect in the relation between social worker and client, and to embrace a user perspective in the professional practice. Yet, many clients find themselves mistreated and ignored and experience social service work as arbitrary and inaccessible. The purpose of this study is to examine what takes place in the encounter betw

Populärvetenskaplig sammanfattning Spektroskopi handlar om teoretiska modeller och experiment där man observerar ljus som har växelverkat med materia. Spektroskopiska metoder används inom många olika ämnesområden som exempelvis kemi, fysik och biologi. Ett jordnära exempel på tillämpad spektroskopi är människans öga. Reflekterat ljus från olika föremål samlas in av linsen i ögat, avbildas på näthiIn this thesis a novel spectroscopic method consisting of a combination of frequency domain photon migration (FPDM) and gas in scattering media absorption spectroscopy (GASMAS) is developed, for assessment of the mean optical path length and gas absorption in porous media. The system stability is experimentally investigated and measurements are performed on balsa and pine wood to evaluate the rela

Thomas Quick erkände under 1990-talet ett 30-tal mord som han påstod att han begått i Sverige, Norge, Danmark, och Finland under åren 1964-1993. Han dömdes för åtta av dem. 18 år senare, i december 2008, tar han tillbaka alla sina erkännanden av mord och begär resning för samtliga fällande domar. Detta har hittills resulterat i tre frikännande domar samt två positiva resningsbeslut. Pelle Svensson1990 Thomas Quick confessed to around 30 murders that he claimed to have committed in Sweden, Norway, Denmark and Finland around the years 1964-1993. He was convicted for eight of them. 18 years later he takes back his confessions of murder and applies for remedy for all his convictions. This has so far resulted in three acquittals and five granted trials of remedy. Pelle Svensson, lawyer and auth

To establish what a woman’s traditional place is this thesis compares Coventry Patmore’s poem “The Angel in the House” to Virginia Woolf’s speech “Professions for Women.” It then goes on to analyze the main women characters of five literary works that demonstrate and counter this
