Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

Popular Abstract in Swedish Värmestrålning är högst relevant i förbränningsmiljöer. I dessa miljöer är förbränningsgaser och partiklar den huvudsakliga källan till värmestrålning. Förbränningsmiljön är komplex att beskriva. Analys av turbulenta flöden, kemiska reaktioner och transport av energi måste göras för att fullständigt beskriva miljön. Att kunna beskriva dessa fenomen är en viktig del i föThermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. This thesis has focused on studying thermal radiative property models of the participating media, gases and particles. Two specific combustion

Design as a linguistic activity

Design starts with a cognitive model and ends with a solution worked out in a way that fits into the human context of meaning which is socially decided. The bridge between the cognitive model and the final system, or thing, is a proper description that has to be possible to socially communicate. The necessary description part leads to the understanding that design, like sciences, is a kind of lear

A Case Study on Benefits and Side-Effects of Agile Practices in Large-Scale Requirements Engineering

In the software industry, there is a strong shift from traditional phase-based development towards agile methods and practices. This paper reports on a case study aimed at investigating if, and how, agile Requirements Engineering (RE) can remedy the challenges of traditional RE, and what new challenges agile RE may pose. The results from an initial case study with 9 practitioners from a large soft

Soot sensors for efficient combustion and low emissions - SootSensII

Nanosized soot particles are a serious health hazard in urban air. Upon inhalation they can penetrate deep into the lungs and their fat solubility makes possible their accumulation in other organs such as the brain. For this reason legislation has continuously reduced the allowable emission levels and raised requirements for reporting the status of the exhaust system (OBD, on board diagnostics) in

No title

This paper presents the 1936 Spanish general elections as they were seen at the time by the Swedish Envoyé in Madrid and by the Swedish press. While there is plenty of Swedish historical research on Sweden’s role in the Spanish civil war, there are very few studies on the relationships between Sweden and the Spanish Republic before July 1936. Therefore, this study relies almost entirely on two gro

Effects of created habitats on farmland biodiversity

Popular Abstract in Swedish Stora förändringar har skett i jordbrukslandskapet under det senaste drygt halva århundradet. Ett allt intensivare jordbruk med krav på större skördar för att möta en allt större efterfrågan på livsmedel har satt sina spår. För att klara de högre kraven, men också som en följd av den teknologiska utvecklingen, så har jordbruket rationaliserats. Landskapet har strukturerAgricultural intensification has caused severe declines among biodiversity in European farmland over the last half century. The transformation of the agricultural landscape has led to reduced availability of key resources such as food, nesting habitat and shelter. In this thesis I have investigated a way of ameliorating the negative effects of agricultural intensification, through the creation of

Why Trading with Dictators May Nevertheless Help the People: On the Interplay between Trade, Political Regimes and Economic Institutions

Recent empirical studies confirm a positive relationship between trade liberalization or trade openness and the quality of domestic economic institutions. An isolated analysis of trade openness per se, however, may grossly simplify the mechanisms at work, as the linkage between open trade and quality of economic institutions is likely to vary for different political regimes. This study examines th

The Role of F0 and Duration in Perception of Female and Male Speaker Age

Single word stimuli from twelve female and twelve male natural speakers of various ages and from two synthetic voices were acoustically analyzed for duration and F0. Listening experiments were carried out to test if spectral features or F0 and duration provide the more dominant age cues and to test if listeners are equally good at estimating the age of female and male speakers. Results of the list

Higher Education for Girls in North American College Fiction 1886-1912

Popular Abstract in Swedish Från 1865 och framåt öppnades i nordöstra U.S.A ett antal college där unga kvinnor kunde avlägga en icke yrkesinriktad akademisk examen. Efter några decennier använde några som utexaminerats från dessa institutioner sina erfarenheter i populära berättelser om studenter på college. Avhandlingen visar hur denna utbildning presenteras i skönlitterär form. Fokus ligger på Twenty years after Vassar College welcomed the first American female undergraduates in 1865, the experiences of women college students began to be fictionalized in so-called college stories. This thesis shows how higher education is presented in the novels, collections of short stories, and serialized stories for female readers published before the United States was involved in the First World Wa
