This paper addresses design space exploration for streaming applications (such as MPEG) running on multi-processor platforms with guaranteed service interconnects. In particular, we solve mapping, path selection and router configuration problems. Given the complexity of these problems, state of the art approaches in this area largely rely on greedy heuristics, which do not guarantee optimality. Ou
Traditional efforts in standardizing video coding used to involve a lengthy process that resulted in large monolithic standards and reference codes. This approach has become increasingly ill-suited to the dynamics and the fast changing needs of the video coding community. Most importantly, there used to be no principled approach to leveraging the significant commonalities between the different cod
A major challenge when designing general purpose graphics hardware is to allow efficient access to texture data. Although different rendering paradigms vary with respect to their data access patterns, there is no flexibility when it comes to data caching provided by the graphics architecture. In this paper we focus on volume ray-casting, and show the benefits of algorithm-aware data caching. Our M
Partially premixed combustion (PPC) is a combustion concept with similarities to both Diesel and Homogeneous Charge Compression Ignition (HCCI) combustion. It provides a combustion mode with better controllability than HCCI without increasing the emissions of nitrogen oxides and soot to the level of traditional Diesel engines. The model described in this paper aims to describe the main features of
The European Union has initiated a number of initiatives to improve resource efficiency in Europe. The Ecodesign Directive is one of the policy instruments that could aid the transition towards a more resource efficient economy. So far, the Directive has mainly been applied to set requirements related to energy efficiency, but there is potential for setting legal standards that increase product du
Popular Abstract in Swedish Avhandlingen syftar till att bidra till förståelsen av hur det kan komma sig att kristendomen i början av det andra århundradet utvecklas till en icke-judisk religion. Att de judendom och kristendom idag uppfattas som två olika religioner är inte så märkligt. Dock, om man betänker att kristendomen ursprungligen var en del av det första århundradets judendom så är det egThis book attempts to answer the question of how it is possible that Christianity in the beginning of the second century C.E. had developed into a non-Jewish, Gentile religion. Since Christianity was originally one of many Jewish factions within the diversified Judaism of the period, and one that even primarily seems to have directed its attention to the people of Israel, the problem of its separa
Light maps have long been a popular technique for visually rich real-time rendering in games. They typically contain smooth color gradients which current low bit rate texture compression techniques, such as DXT1 and ETC2, do not handle well. The application writer must therefore choose between doubling the bit rate by choosing a codec such as BC7, or accept the compression artifacts, neither of wh
A critical comparison of two mid 19th century versions of the story of As’ad al-Shidyâq, a young Maronite who became the first Protestant sympathiser in Lebanon; the first version written by an American missionary (Isaac Bird), the second by a Lebanese intellectual (Butrus al-Bustani) who became a Protestant. The comparison reveals differences between expatriate and indigenous perceptions of Prote
In this paper we address the problem of generating efficient software implementations for a large class of dataflow programs that is characterized by highly data-dependent behavior and which is therefore in general not amenable to compile-time scheduling. Previous work on implementing dataflow programs has emphasized classes of stream processing algorithms that exhibit sufficiently regular behavio

In this paper, we derive compact representations of the depth function for a triangle undergoing motion or defocus blur. Unlike a static primitive, where the depth function is planar, the depth function is a rational function in time and the lens parameters. Furthermore, we show how these compact depth functions can be used to design an efficient depth buffer compressor/decompressor, which signifi
In this paper, we present a meshing scheme for the implementation of an adaptive tessellation of triangular meshes on the graphics processing unit (GPU). Tessellation is performed according to a local test to generate primitives dynamically. The refinement procedure does not require the pre-computation of any refinement pattern. The resulting adaptive procedure is efficient and simple, and generat
Although Moral Foundations Theory claims that the foundations of morality are universal, there are still few studies addressing it through non-English measures. In the current research, 540 persons filled out a Swedish translation of the Moral Foundations Questionnaire, and 332 of them filled out political attitude measures. Confirmatory factor analyses suggested that the fit of the five-factor mo
We present user-controllable and plausible defocus blur for a stochastic rasterizer. We modify circle of confusion coefficients per vertex to express more general defocus blur, and show how the method can be applied to limit the foreground blur, extend the in-focus range, simulate tilt-shift photography, and specify per-object defocus blur. Furthermore, with two simplifying assumptions, we show th
