AbstractThis paper presents a fast surface voxelization technique for the mapping of tessellated triangular surface meshes to uniform and structured grids that provide a basis for CFD simulations with the lattice Boltzmann method (LBM). The core algorithm is optimized for massively parallel execution on graphics processing units (GPUs) and is based on a unique dissection of the inner body shell. This unique definition necessitates a topology based neighbor search as a preprocessing step, but also enables parallel implementation. More specifically, normal vectors of adjacent triangular tessellations are used to construct half-angles that clearly separate the per-triangle regions. For each triangle, the grid nodes inside the axis-aligned bounding box (AABB) are tested for their distance to the triangle in question and for certain well-defined relative angles. The performance of the presented grid generation procedure is superior to the performance of the GPU-accelerated flow field computations per time step which allows efficient fluid-structure interaction simulations, without noticeable performance loss due to the dynamic grid update.

The paper deals with the concept of matter manipulation and its vitality in the Brothers Quay’ works. The matter manipulation is not limited to the actual “matter”. Brothers Quay perceive the acting “matters” as symbols and signs of human activities and relationships. For them, there is no fundamental difference between “matters” and living beings inhabiting their films. Matter manipulation is the process of “machine” production, reproduction, destruction, repair and deconstruction. The creation process acts as a magic spell, in which objects are transformed into something else. The Street of Crocodiles (1986) is an example of deep understanding of lifelessness as a mask, a kind of conspiracy, behind which unknown life forms hide. Brothers Quay’ creative works tell us about autonomous existence of objects beyond their direct utilitarian purpose. The article will be devoted to such problems as synergistic vision of the world in which the material and the spiritual are inseparable. Despite the paradox of visual embodiment, it fits into a philosophical metatheory of the “new materialism”, which transversely crosses streams of matter and mind, body and soul, nature and culture. The legacy of Brothers Quay open to us the world of ordinary, “banal” things, signs of time on their body shell, in contradiction with the dominance of endless consumption of new, intrusive advertising and cult of youth, in which there is no room for “sign of the times”. Santrauka Straipsnio objektas – manipuliavimo materija ir jos vitališkumo koncepcija brolių Quay darbuose. Manipuliavimas materija neapsiriboja tikrąja „materija“. Broliai Quay veikiančiąją „materiją“ supranta kaip žmonių veiklos bei santykių simbolius ir ženklus. Jų manymu, nesama esminio skirtumo tarp „materijos“ ir gyvų būtybių jų filmuose. Manipuliavimas materija – tai „mašininio“ produkavimo, reprodukavimo, destrukcijos, taisymo ir dekonstravimo procesas. Kūrybos procesas – tai tarsi magiškas akimirksnis, kurio metu objektai transformuojami į kažką kita. Krokodilų gatvė – tai negyvybingumo kaip kaukės, tam tikros konspiracijos, anapus kurios glūdi nepažintojo gyvenimo formos, gilaus supratimo pavyzdys. Brolių Quay kūrybos darbai byloja apie autonomišką objektų egzistenciją anapus jų tiesioginių utilitarinių tikslų. Straipsnis skirtas tokioms problemoms, kaip sinergetinis pasaulio, kuriame materija ir dvasia yra neatsiejamos, matymas. Nepaisant vizualiojo įkūnijimo paradokso, jis pritaikomas „naujojo materializmo“ filosofinei metateorijai. „Naujasis materializmas“ skersai išilgai kerta materijos ir sąmonės, kūno ir sielos, gamtos ir kultūros klodus. Brolių Quay palikimas atveria įprastinių, „banalių“ daiktų pasaulį, laiko ženklus jų kūniškumo lentynoje, visa tai priešpastatydamas neišsenkančiam naujosios įkyrios reklamos ir jaunystės kulto vartojimo dominavimui – pastarojo sąlygomis nesama vietos „laiko ženklų“ kambariui.

The main objective of this work was to introduce Reflexive Photoelasticity Technique in qualifying automotive components at Fiat Automoveis S.A in Brazil. Actual stresses were determined in a simple geometry plate and also in nodes of a body shell of a passenger vehicle by using reflexive photoelasticity methodology. Initially, tests were performed in welded steel plates submitted to traction loads. These plates were previously coated with birrefringent plastic material. External loads were applied through hydraulic MTS actuators. Stress and strain distribution in welded points neighboring areas using reflexive polariscope were quantitative determined. Simultaneously, these stress and strains acting on the welded plate were determined using strain gauges. The results from both experimental techniques (photoelasticity and strain gauges) were compared with those obtained from a numerical model using finite element method. The results were correlated and analyzed. Finally, reflexive photoelasticity technique was used to determine the stresses in nodes of a body shell of a passenger vehicle. Through this analysis it was possible to determine critical points in the structure with peak stresses.

1. A new technique for monitoring the deep body temperature is described. The technique depends on creating a zone of zero heat-flow across the body shell; this brings the deep body temperature to the skin surface where it is measured with a simple electronic thermometer. 2. The new device gives a temperature closely comparable with other methods for measuring the deep body temperature in the resting subject, and is simple to use and socially acceptable.
