We define a ray, show how to use ray intervals, and demonstrate how to specify a ray using DirectX Raytracing (DXR).

The traditional quadratic formula is often presented as the way to compute the intersection of a ray with a sphere. While mathematically correct, this factorization can be numerically unstable when using floating-point arithmetic. We give two little-known reformulations and show how each can improve precision.

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.

Background. Chaos Engineering is proposed as a practice to verify a system’s resilience under real, operational conditions. It employs fault injection, is originally developed at Netflix, and supported by several tools from there and other sources. Aims. We aim to intro- duce Chaos Engineering at ICA Gruppen AB, a group of companies whose core business is grocery retail, to improve their systems’

Presupposition is surely one of the most debated notions in the linguistic and philosophical literature. Historically, there are two main theoretical approaches to presuppositions. According to the first one, the semantic view, presuppositions are semantic implications, that is, truth-conditional relations between propositions and statements. In this sense, presuppositions are considered propertie

The aim of this study is to investigate whether native speakers of Gallipolino, bilectals who have acquired Gallipolino as L1 (together with standard Italian) in their childhood, who have left Gallipoli after puberty and currently use standard Italian as their primary language, display effects of attrition with respect to subordinate clauses embedded under the complementizers ku and ka. Our hypoth

This thesis is a collection of three empirical papers that tests hypotheses within the context of two related and intersecting theoretical frameworks: rational expectations and efficient markets. The aim is to empirically explore to what extent households form their inflation expectations in a rational manner, and to explain why households’ perceptions may deviate from the measured official rate.

We present a novel texture compression scheme, called iPACKMAN, targeted for hardware implementation. Interms of image quality, it outperforms the previous de facto standard texture compression algorithms in the majority of all cases that we have tested. Our new algorithm is an extension of the PACKMAN texture compressionsystem, and while it is a bit more complex than PACKMAN, it is still very low
