We describe simple methods for how to filter environment maps using ray cones and ray differentials in a ray tracing engine.

Reducing train delays important in many countries, even in those like Japan, where punctuality is already high. There is a clear pattern across the literature that the delays typically occur at stations and are recovered on line sections. Previous work has shown that one explanation for this is that trains interact at stations. When trains have different speeds or stopping patterns, overtakes are Reducing train delays important in many countries, even in those like Japan, where punctuality is already high.

Genetic correlations for a trait across environments are predicted to decrease as environments diverge. However, estimates ofgenetic correlations from natural populations are typically defined across a limited environmental range and prone to very largestandard errors, making it difficult to test this prediction.

Software products are rarely developed from scratch and vulnerabilities in such products might reside in parts that are either open source software or provided by another organization. Hence, the total cybersecurity of a product often depends on cooperation, explicit or implicit, between several organizations.We study the attitudes and practices of companies in software ecosystems towards sharing Software products are rarely developed from scratch and vulnerabilities in such products might reside in parts that are either open source software or provided by another organization.

Interaction of synthetic TiO2 (anatase) nanoparticles in aqueous suspension at pH 5 was investigated as a function of time in the presence of various organic molecules in terms of adsorption and aggregation behaviour. ζ-potential and average particle diameter were determined with electrophoretic and dynamic light scattering, respectively, while batch adsorption experiments were used to quantify th

Växelverkningar mellan små och stora molekyler har konsekvenser för reaktioner som kemister utför i sina provrör, lika mycket som för de livsnödvändiga reaktionerna som sker i vår kropp och våra celler. Förståelsen av dessa växelverkningar är nyckeln till att kunna utnyttja dem till vår fördel, till exempel i industriella processer eller i utveckling av mediciner. För att uppnå detta kan man utförThe influence of small and large, charged molecules on the properties of aqueous interfaces has important implications in chemistry, biology, and medicine. For example, at the surface of marine aerosols, the presence of halide anions and tropospheric gases gives way to multiphase chemical reactions affecting climate and air quality. In this Thesis, we investigate three different systems and phenom

DIY Performance Culture in Folkets Park. Ian Muller This thesis is a qualitative applied cultural analysis of Folkets Park, Malmö: specifically Do It Yourself (DIY) creative theatrical performance as a form of playing. During the summer of 2012, over 1,000 quantitative Social Return on Investment surveys were collected for the city to assess the park’s ‘value’ to visitors compared to the municip

In this essay, I investigate whether Solomonoff’s prior can be used to solve the problem of the priors for Bayesianism. In outline, the idea is to give higher prior probability to hypotheses that are "simpler", where simplicity is given a precise formal definition. I begin with a review of Bayesianism, including a survey of past proposed solutions of the problem of the priors. I then intr

This paper analyses how racial wage gaps amongst women in the Brazilian urban labour market have evolved in response to a strong increase in workers’ skills between 2001 and 2011. For this purpose, Melly (2005, 2006) quantile decomposition frameworks will be applied using PNAD data. In so doing we acknowledges a gap in the literature by focusing on women instead of men, extending wage decompositio

Abstract Through the concept of discourse we understand how the reality in one domain is constructed through linguistic combinations, where each of the signs receives its meaning in relation to one another . In the following essay I analyze, through Laclau and Mouffe’s discourse theory, how the Sweden Democrats is trying to frame and establish their political discourse on immigration in the Swed

Thesis purpose: The purpose of this thesis revolves around investigating which factors a company should consider when attempting to dual brand a wide array of products. Methodology: Our thesis intends to investigate the opinions of dual branding among FMCG companies within the Swedish market. We have conducted a qualitative approach, consisting of interviewing five marketing practitioners, mostly

The aim of this paper is to investigate the performance of hedge funds during the period between December 1999 and March 2012. We consider 8 different investment styles for the European market. As it has been argued in several papers hedge funds differ from traditional funds, since it allows for diversification and lower systematic risk. Previous studies show inconclusive results regarding whether

There is probably millions of photographs in the world that no one knows about because of the difficulty archivists have writing about them. It is exceedingly difficult to classify and describe photographs and very often textual models for written sources are applied uncritically to visual materials. Most libraries, archives and museums are now involved in the process of digitisation to improve ac

Background: Life skills-based approaches are broadly used in HIV prevention programmes world-wide. However, evaluations of such programmes have found mixed evidence for their effects on indicators of safer sexual behaviour. Methods: Questionnaires of 4,381 participants of the Star for Life (SFL) life skills-based prevention programme in South African schools were analysed using binary logistic reg

Problem - Trust has the potential to reduce risk and uncertainty that is inherent within entrepreneurial activities. However, few entrepreneurship studies have examined the role of trust during the venture creation process. Additionally, researchers have called for more studies exploring trusting entrepreneurial behaviour and processes across different contexts. Aim - This study aimed to add to t

The 13th of October 2006, the Swedish parliament approved a change in the Foreign Policy. For the first time the Government choose to use a maritime unit in peace-time operations. This had never been done before. The Swedish navy was trained and ready for this, due to the new overall policy, regarding the Armed Forces of Sweden from 2004. The aim of this study is to analyse the process of agenda s

Uppsatsen behandlar delvis internets betydelse för andrahandsmarknaden av kläder men framförallt vilka motiv konsumenterna har när de handlar begagnade kläder via internet. Teorin som används är Pierre Bourdieus teori om smak, fält, habitus och olika former av kapital. Metod för insamling av data bestod av kvantitativ metod i form av webbaserad enkät. Resultatet analyserades sedan i statistiskanal

As such it is a grammatical system learned by native speakers of Arabic through formal education. Case endings are traditionally regarded as an essential feature of Standard Arabic, but morphological case endings are used only sporadically in extemporaneous speech in formal situations where Standa

In this study we investigated if stereotype conceptions against groups of people can be suppressed by retrieval practice and thereby affect implicit associations. Previous research of retrieval-induced forgetting has shown that interfering memories are inhibited and weakened by retrieval practice. Our hypothesis was that retrieval practice of features incongruent to a stereotype would cause memory

This thesis will look at the profession of Town Planning from an economic perspective utilising New Institutional Economics (NIE) to focus on how different institutions and structures bring about efficiency trade- offs. As planning systems have considerable influence over property rights (the ability to affect one‟s own lands) and over transaction costs by intervening in land markets, planning ins
