A review of residual stress analysis using thermoelastic techniques [PDF]

, 2009
Thermoelastic Stress Analysis (TSA) is a full-field technique for experimental stress analysis that is based on infra-red thermography. The technique has proved to be extremely effective for studying elastic stress fields and is now well established.

Current Stress Minimization Based on Particle Swarm Optimization for Dual Active Bridge DC–DC Converter

Actuators
Under extended-phase-shift (ESP) control, the current stress of the dual active bridge converter (DAB) is relatively high, which reduces the efficiency of the converter.

Embodied stress: The physiological resonance of psychosocial stress [PDF]

, 2018
Psychosocial stress is a ubiquitous phenomenon in our society. While acute stress responses are necessary and adaptive, excessive activation of neurobiological stress systems can predispose an individual to far-reaching adverse health outcomes. Living in

Investigation on Degradation of SiC MOSFET Under Surge Current Stress of Body Diode

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020
Eliminating antiparallel silicon carbide Schottky barrier diode (SiC SBD) and making use of the intrinsic body diode of SiC metal–oxide–semiconductor-field-effect transistor (SiC MOSFET) offer a cost-effectiveness solution without obviously sacrificing ...

Time dependent dielectric breakdown and stress induced leakage current characteristics of 8Å EOT HfO2 N-MOSFETS [PDF]

, 2010
In this work we present the time dependent dielectric breakdown (TDDB) characteristics of LaO capped HfO2 layers with an equivalent oxide thickness of 8Å. The layers show maximum operating voltages in excess of 1V. Such high reliability can be attributed

Current Methods to Detect Stressed Staphylococci

Journal of Food Protection, 1979
Many of the operations employed in food processing can sublethally damage staphylococci, temporarily rendering the cells incapable of growth on selective media commonly employed for their enumeration. Stressed staphylococci are, under the proper conditions, capable of recovery and subsequently normal growth, including enterotoxin production by some ...
