As a solution to solving energy consumption and environment problems, photovoltaics has become one type of the promising devices to convert solar energy into electricity directly. In some special areas like in space, a kind of photovoltaics with lightweight and reliable properties is needed to supply power. Therefore, photovoltaics based on the group III-V semiconductor nanowires has been emerged
Den flerspråkiga texten bör studeras och förstås som en situerad händelse. Det är utgångspunkten i denna artikel, som med Caroline Bergvall och hennes ensembles framförande av Drift i norra Italien i september 2018 – och hennes bok med samma namn från 2014 – som exempel undersöker hur och ifall Roman Jakobsons kommunikationsmodell från 1958 kan bidra till en djupare förståelse av verket. Genom att
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.
