Chemical admixtures are an essential ingredient of modern concrete mix, but many their molecular scale working mechanisms remain poorly described. In this respect, recent advances in computational methods, provide a unique opportunity to gain the needed level insights into mechanism action chemical cementitious systems. Such studies slowly increasing number and paper proposes review on approach...

Abstract This paper investigates the thermal modeling challenges of high-speed motorized spindles up to 40,000 rpm. The expansion and deflection are critical determinants for resulting tool center point displacement achievable machining accuracy machine tools. In order compensate, finite element reduced physical models (digital twins) therefore require an accurate understanding boundary conditi...

Robotics is becoming more and ubiquitous, but the pressure to bring systems market occasionally goes at cost of neglecting security mechanisms during development, deployment or while in production. As a result, contemporary robotic are vulnerable diverse attack patterns, posteriori hardening least challenging, if not impossible all. This book aims stipulate inclusion robotics from earliest desi...
