Ray Tracing Methods for Correcting Chromatic Aberrations in Imaging Systems
International Journal of Optics, 2014 The correction of chromatic aberrations is typically performed using aberration formulas or by using real ray tracing. While the use of aberration formulas might be effective for some simple optical systems, it has limitations for complex and fast ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions
Advanced Functional Materials, EarlyView.This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Selective rendering for efficient ray traced stereoscopic images [PDF]
, 2009 Depth-related visual effects are a key feature of many virtual environments. In stereo-based systems, the depth effect can be produced by delivering frames of disparate image pairs, while in monocular environments, the viewer has to extract this depth ...

Advanced Functional Materials, EarlyView.DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

DS-CDMA microcellular networks with adaptive antennas [PDF]
, 1996 This paper considers the performance of a DS-CDMA system which employs adaptive antenna technology at the basestation site of a microcell. Results for a typical microcellular environment produced with the help of a ray tracing tool highlight the ...

Parallelisation of the ray-tracing algorithm [PDF]
, 1994 The two typical methods for distribution of ray-tracing rendering algorithm are presented in this article. The implementation of a distributed ray-tracer on a network of UNIX workstations is described in details. The first results are discussed from the point of view of memory load, time of computation and cost of communication among processes.

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips
Advanced Functional Materials, EarlyView.This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...
