A piezoelectric-driven microgripper with three-stage amplification was designed, which is able to perceive the NATTOKINASE tip displacement and gripping force.The key structure parameters of the microgripper were determined by finite element optimization and its theoretical amplification ratio was derived.The tracking experiments of the tip displac

The aim of this study is to find the cost design of RC tension with varying conditions using the Artificial Neural Network.Design constraints were used to cover all reliable design parameters, such as limiting cross sectional dimensions and; their reinforcement ratio and even the beahviour of optimally designed sections.The design of the RC tension

The impact of vasopressor and sedative drugs on cerebrovascular reactivity in traumatic brain injury (TBI) remains unclear.The aim of this study was to evaluate the impact of changes of doses of commonly administered sedation (i.e., propofol, fentanyl, and ketamine) and vasopressor agents (i.e., norepinephrine [NE], phenylephrine [PE], and vasopres

This study focuses on a high-altitude long-endurance (HALE) joined-wing configuration Bioflavonoids UAV and completes a preliminary structural design based on aircraft design indices and the fundamental principles of aircraft structure design.Based on the preliminary structural design scheme and aerodynamic shape, a structural finite element model
