No full textRelative flattening between velvet and matte 3D shapes: Evidence for similar shape-from-shading computations
No full textAmong other cues, the visual system uses shading to infer the 3D shape of objects. The shading pattern depends on the illumination and reflectance properties (BRDF). In this study, we compared 3D shape perception between identical shapes with different BRDFs. The stimuli were photographed 3D printed random smooth shapes that were either painted matte gray or had a gray velvet layer. We used the gauge figure task (J. J. Koenderink, A. J. van Doorn, & A. M. L. Kappers, 1992) to quantify 3D shape perception. We found that the shape of velvet objects was systematically perceived to be flatter than the matte objects. Furthermore, observers' judgments were more similar for matte shapes than for velvet shapes. Lastly, we compared subjective with veridical reliefs and found large systematic differences: Both matte and velvet shapes were perceived more flat than the actual shape. The isophote pattern of a flattened Lambertian shape resembles the isophote pattern of an unflattened velvet shape. We argue that the visual system uses a similar shape-from-shading computation for matte and velvet objects that partly discounts material propertiesIndustrial Design Engineerin
Support for teaching graphics in matte -painting
No full textTITLE: Support for teaching graphics in matte-painting AUTHOR: Tomáš Vachuda DEPARTMENT: Department of Information Technology and Education SUPERVISOR: Mgr. Stanislav Lustig ABSTRACT: This thesis serves not only as a handbook for those who are interested in Matte painting, but also as a universal instruction manual on realistic photomanipulations. The thesis is divided into the theoretical and practical part. In theoretical part it describes the content and the very essence of this subject. It tells the history of matte painting and describes traditional tools, which were used for this technique in past and digital tools, which are being used nowadays. It explains basic rules, which - when followed - provides photorealistic results. Practical part is based on the theoretical part and demonstrates specific and detailed method, which results in professional photomanipulation. The main goal of the thesis is to give the public the insight into this technique. To ordinary people, this term is often unknown, even although we come across the visual form of this technique in most of the movies or in commercials. Practical part of this thesis is in form of tutorial and serves as a educational material, which will teach the reader not only the technique of Matte painting, but also the advanced manipulation with the..

Novel fluxing strategy of copper matte smelting and trace metals in E-Waste recycling
No full textFunding Information: This study was partly financially supported by Aalto University, School of Chemical Engineering. Min Chen acknowledges the financial support from the China Scholarship Council [number #201806370217]. RAMI (Raw Materials Infrastructure) by Academy of Finland hosted by Aalto University, VTT and GTK at Otaniemi Campus was used in this investigation. Publisher Copyright: © 2022 The Author(s)The distribution behavior of trace metals between copper matte and spinel-saturated iron silicate slags was investigated at 1250 °C and pSO2 of 0.25 atm at low silica concentrations. The experiments were conducted in magnetite (Fe3O4) spinel crucibles in controlled CO-CO2-SO2-Ar gas mixtures using a high-temperature equilibration-quenching technique. The concentrations of trace elements in matte, spinel, and slag were quantified by electron probe X-ray microanalysis and laser ablation-inductively coupled plasma-mass spectrometry. The trace metals (Ag, Ni, Co, and Sn) in all phases and their distribution coefficients were calculated as a function of matte grade. Results show that silver and nickel can be effectively recovered into matte, whereas cobalt and tin are predominantly deported into slag and gas phases, respectively. These results augment the fundamental thermodynamic data of trace metal distributions in copper smelting processes at low-silica fluxing practices.Peer reviewe
Industrial Deportment of Minor and Trace Elements in Direct Nickel Matte Smelting
No full textPublisher Copyright: © The Author(s) 2024.A sampling campaign was carried out at an industrial nickel flash smelter with the aim of evaluating the trace element distributions along the smelting line from raw materials to high-grade nickel matte and discard slag. The industrial technology was direct-to-nickel matte smelting without conventional Peirce–Smith converters, thus having two different nickel mattes as smelting products and feeds in the refinery: the sulfidic low-iron nickel matte from smelting furnace and the low-sulfur electric furnace matte from slag cleaning. Major and trace element concentrations were obtained from the solidified samples by electron probe microanalysis and laser ablation–inductively coupled plasma–mass spectrometry. Due to the industrial sampling environment, i.e., the slow cooling rate of the samples, not all the trace element concentrations were able to be measured at the lowest detection limits of the techniques used in some of the phases formed after cooling. However, the obtained results and element distribution coefficients were in good agreement with equilibrium values published in the literature.Peer reviewe
Transient supramolecular hydrogels formed by catalytic control over molecular self-assembly
No full textThe present work shows how transient supramolecular hydrogels can be formed by catalytically controlled molecular self-assembly. Catalysis formation of molecular gelators leads the self-assembly along a kinetically favored pathway, resulting in transient hydrogels. This work demonstrates an effective approach towards pathway-dependent supramolecular materials.Accepted Author ManuscriptChemE/Advanced Soft Matte
