Background. Foam rolling has been shown to acutely increase range of motion (ROM) during knee flexion and hip flexion with the experimenter applying an external force, yet no study to date has measured hip extensibility as a result of foam rolling with controlled knee flexion and hip extension moments. The purpose of this study was to investigate the acute effects of foam rolling on hip extensi...

This paper presents our work in developing an autonomous micromanipulation system. The originality of our system is that it takes advantage of adhesion forces to grip micro-objects using an AFM (Atomic Force Microscopy) probe. A theoretical analysis of rolling conditions is carried out in order to achieve precise release of an object picked-up by adhesion. Vision control, based on the specifici...

Due to the inaccuracy of preset rolling force cold rolling, there is a severe thickness defect in strip head after due flying gauge change (FGC), which affects yield strip. This paper establishes model (RFPM) by combining optimization (RFOM) and deviation prediction (RFDPM). The RFOM used genetic algorithm (GA) optimize deformation resistance friction coefficient models. RFDPM constructed using...

Applications of carbon nanotubes (CNTs) in flexible and complementary metal-oxide-semiconductor (CMOS)-based electronic and energy devices are impeded due to typically low CNT areal densities, growth temperatures that are incompatible with device substrates, and challenges in large-area alignment and interconnection. A scalable method for continuous fabrication and transfer printing of dense ho...

It has great significance to research the dynamical reliability probability of rolling mill rolls system for improving its stochastic dynamical reliability and products quality rolled. The fifth-octave vertical vibration stochastic dynamical model of rolls system was established, and the pseudo-excitation method was used to obtain the power spectral density and the variance variation characteri...
