The main idea of this paper is improving fatigue response of a low-alloyed carbon-manganese steel material manufactured by Direct Energy Deposition-Arc technique using post-heat treatments. Four series of fatigue specimens are machined from a 3D printed wall. The machined samples are austenitized following a direct quenching and tempering processes at two different temperatures. All samples are subjected to rotating bending fatigue loading ...

Monocrystalline silicon is currently one of the most used materials in the semiconductor industry. However, being hard and brittle, a silicon wafer commonly suffers from machining-induced subsurface damage (SSD). Detecting SSD is important for optimizing the machining process in order to improve the surface integrity of a machined wafer. Among the various detection methods, the polarized laser scattering (PLS) method has a huge potential in ...

The appearance of 3D scanners, generating point clouds, has revolutionized anthropometric data collection systems and its applications. Anthropometric data is of paramount importance in several applications, including fashion design, medical diagnosis and virtual character modelling, all of which require an fully-automatic anthropometric measurement extraction method. 3D-based methods for anthropometric measurement extraction become more and ...

A modern day light microscope has evolved from a tool devoted to making primarily empirical observations to what is now a sophisticated , quantitative device that is an integral part of both physical and life science research. Nowadays, microscopes are found in nearly every experimental laboratory. However, despite their prevalent use in capturing and quantifying scientific phenomena, neither a thorough understanding of the principles underlying ...

The discovery of melanopsin and the non-visual impact of light, lead to a new era in lighting design. Using a melanopic action spectrum, the CIE introduced the melanopic efficacy of luminous radiation (MELR), which quantifies the influence of light on melanopsin. A significant amount of research has been conducted on the possible variation of this MELR and other related metrics for various practical lighting settings, but the fundamental ...

Despite advances in intraoperative surgical imaging, reliable discrimination of critical tissue during surgery remains challenging. As a result, decisions with potentially life-changing consequences for patients are still based on the surgeon's subjective visual assessment. Hyperspectral imaging (HSI) provides a promising solution for objective intraoperative tissue characterisation, with the advantages of being non-contact, non-ionising and ...

Electrochemical discharge machining (ECDM) can be applied as a non-traditional processing technology for machining non-conductive materials such as glass and ceramics, based on the phenomena of evoked electrochemical discharges around the tool electrode. The material removal mechanism of ECDM is noticeably complex and difficult to experimentally characterize. In this paper, finite element models were proposed to predict the material removal in ...
