Unlike rasterization, where one can rely on pixel quad partial derivatives, an alternative approach must be taken for filtered texturing during ray tracing. We describe two methods for computing texture level of detail for ray tracing. The first approach uses ray differentials, which is a general solution that gives high-quality results. It is rather expensive in terms of computations and ray stor
We describe simple methods for how to filter environment maps using ray cones and ray differentials in a ray tracing engine.
In this thesis, we investigate and develop new methods for efficient and functional use of resources in edge networks. Setting this work aside from previous work, we study User Generated Content (UGC) such as social media information and data generated in the new emerging Internet of Things systems. We present efficient solutions for placing such content and managing which network resources should
Male-only parental care, while rare in most animals, is a widespread strategy within teleost fish. The costs and benefits to males of acting as sole carer are highly variable among fish species making it challenging to determine the selective pressures driving the evolution of male-only care to such a high prevalence. We conducted a phylogenetic meta-analysis to examine the costs and benefits of p
Syfte: Syftet är att undersöka sambandet mellan CDS spreaden och bond spreaden, samt att jämföra dessa över tid. Detta genomförs genom att testa för ett kointegrationssamband samt Granger-kausalitet mellan CDS spreaden och bond spreaden för varje enhet som ingår i urvalet, och för olika perioder. Också deskriptiv statistik används. Metod: Kvantitativ metod: Augmented Dickey-Fuller test, KPSS, Engl
Problematisering: E-handeln är en av globaliseringens och informationsteknologins frukter. Denna konstant utvecklandes affärsområde innebär många fördelar för dess aktörer. Trots detta existerar det svårigheter kring dess kundserviceaspekt. Det är denna faktor som utgör uppsatsens centrala studieämne. Syfte: Uppsatsens ändamål är att förstärka våra kunskaper av e-handeln, sett ur en service manage
Many modern psychological theories still assume that humans know about themselves to a wide and accurate extent, in line with the early classical cognitive frameworks. Other competing frameworks, such as dynamic cognition, propose that intelligent behavior can arise from an interaction between the brain, body, and environment, without the need of manipulating explicitly represented knowledge-state
The danger that mass surveillance poses to concepts of ‘freedom’ and ‘democracy’ have long been a topic of fiction as well as of hard academic study. George Orwell’s Nineteen Eighty-Four is a work that some might disregard as mere post-apocalyptic whimsy but its arguably accurate recreation and prediction of the methods utilized by the totalitarian government to maintain absolute control over a po
This master’s thesis analyses the extent to which EU member states and EU bodies have responded coherently towards China’s Belt and Road Initiative. The master’s thesis uses a mixed method approach: it begins with a comparative study of the Dutch, German, Czech and Hungarian policy responses towards the BRI. These are: an analysis of the national policy stance, the foreign policy stance and an ana
Recently, major infrastructure projects have been started in Denmark and this research tries to answer how social aspects are investigated in planning and analysis work before the big projects are constructed. The research has interviewed representative from the Copenhagen Metro Company and Danish Road Directory to uncover the analysis work and how social aspects are included in their work. The re
Denna uppsats undersöker företags moraliska ansvar att respektera de mänskliga rättigheterna, skisserade i UNGP, som i praktiken genomförs genom en human rights due diligence-process. Den analyserar hur moderbolaget ska genomföra en sådan process i förhållande till sina dotterbolag. Uppsatsen beskriver sedan vilket juridiskt ansvar, enligt engelsk skadeståndsrätt och dess duty of care-begrepp, ett
This study explored the effect of cognitive workload on shooting performance and quiet eye duration (QED) using a Stroop based handgun-shooting task (Stroop shooting). Furthermore, the difference between the reverse Stroop effect and the traditional Stroop effect when shooting based on the Attentional Control Theory was assessed. The methods used were partially based on previously published resear
This thesis discusses areas related to problems of private international law that can arise from an online cross-border violation of personality rights. The thesis can be divided into two parts. One part deals with jurisdictional issues and specifically a discussion regarding Art. 7(2) of the Brussels I bis Regulation and the CJEU’s case law on the topic. The second part deals with choice of law i
In the middle ages the Albanian northern tribes had their own customary law that regulated their everyday life. This customary law is called the Kanun of Lekë Dukagjini. The Kanun of Lekë Dukagjini has been passed on by the old generation orally to new generations and used by highland clans in northern Albania, Kosovo and from Albanian tribes in Macedonia and Montenegro. This oral law regulates cr
Syftet med denna studien är att bidra med kunskap om hur medarbetarna ser på sin användning av LinkedIn i förhållande till sin organisation. För att uppnå detta krävs en djupare förståelse för medarbetares användning och upplevelse av LinkedIn. Tidigare studier som undersöker LinkedIn har främst fokuserat på hur rekryterare kan använda plattformen och inte hur enskilda medarbetare använder plattfoThe purpose of this study is to contribute with knowledge about how employees perceive their LinkedIn usage in relation to their organization. To increase the awareness of how organizations can work strategically with LinkedIn the link between organizations and employees has been studied. Other studies examining LinkedIn have mostly had a recruiter perspective or have not considered users as emplo
In the past ten years, Greece has been hit by two “crises”. The first, an economic crisis in 2009, which consisted of a series of bailouts from the European Commission, European Central Bank, and the International Monetary Fund, leading to a trend of anti-Greek sentiment within the EU. The second, the Syrian refugee “crisis”, beginning in the fall of 2015. At the start, Greece was simply a transit
The legal paradox. Which factors are decisive in honour-related cases for compulsory care of young persons? Previous studies have shown that honour-related violence and oppression has grown to become a major problem in Sweden. The municipal social service is obliged to help and support all people who become victims of violence. Yet, several municipalities in Sweden have been criticized for their
Plastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. Synthetic hormones are widely used in contraceptives and medications and one of the most common synthetic hormones used is 17-alpha-ethinylestradiol (EE2)
This study revives a heavily debated relationship between government debt accumulation and economic growth. Although indebtedness levels stay high, current economic growth forecasts seem optimistic not only in the euro area but in other advanced countries, as well. 24 advanced OECD economies are investigated to understand if financial outcomes are detrimental to the real economic variables in the
