A Better Technique for Controlling Torque to Preload Relationship in the Accurate Assembly of Tiny Threaded Bolt Joints
Abstract: Our industrial, commercial, and even civil worlds are made possible by threaded fasteners or connections, which include all types of bolts. They offer an easy way to connect a limitless number of small parts to form large and practical objects like printing presses, cars, airplanes, and buildings. This paper describes the ways to determine torque to preload relationship in threaded connection and finalizing the optimum torque to be applied. Explains …

Enhanced Sensitivity Iontronic Pressure Sensor Gauge Using Laser-Created Micro-Pyramid Structures for Wide Linear Range
Abstract: The achievement of high sensitivity, ultrahigh pressure resolution, and great linearity across a wide pressure range under huge pressure preloads remains a challenge despite the substantial development of flexible capacitive pressure sensors. Here we offer an ultrathin ionic layer-integrated microstructure creation process that is configurable. At 1700 kPa, the sensor's linear range sensitivity is 33.7 kPa-1; at 2000 kPa, the pressure resolution is 0.00725%, and the detection limit is 0.36 …

A study on Controlling Artificial Heart
Abstract: The artificial heart has moved from a visionary concept to a clinically viable organreplacement technology, yet its longterm success hinges on the sophistication of its control architecture. This paper presents a comprehensive investigation of closedloop control strategies that enable an artificial heart to mimic the dynamic, beattobeat adaptability of its biological counterpart. We first construct a highfidelity cardiovascular model that integrates ventricular elastance, systemic and pulmonary vascular compliance, and realtime …
