El control de la inmigración existente en aquellos años coincidentes con la contienda civil y los que siguieron a la misma se regía por unas disposiciones que, a pesar de hundir sus raíces en etapas anteriores y habe...

Artificial assumptions are needed to set the generalized stress paths in hollow cylinder apparatus (HCA). The resulting limitations to imitate the generalized stress paths in HCA are analyzed. According to the function t...

Regenerative bicycle trainers support more sustainable indoor cycling by converting a rider’s kinetic energy into electrical energy while producing a controllable resistive load. For a realistic riding feel, the relati...

Abstract Thermal stress in electric two-wheeler hub motors is a major bottleneck affecting drivetrain reliability, safety, and efficiency—especially under varied terrain, aggressive riding profiles, and sensor reliabil...

Abstract This paper proposes an integrated and optimally tuned photovoltaic water pumping system (PVWPS) with high performance and operational stability under variable climatic conditions. The pumping process starts with...

Abstract The lower limb exoskeletons are used to assist wearers in various scenarios such as medical and industrial settings. Complex modeling errors of the exoskeleton in different application scenarios pose challenges ...

Introduction. Stator flow-oriented control is currently the most widely used system in industry or in previous research for improving the quality of mechanical power generated by permanent magnet synchronous motors (PMSM...

Introduction. In recent days, electric vehicles, robotics and in many control system applications, permanent magnet synchronous motors (PMSMs) are widely utilized. Problem. Due to non-linear behavior of system, external ...

Emergency evasive maneuvers unfold in short near-limit windows in which combined-slip saturation, load transfer, and rapidly varying friction make onset-computation budget and model mismatch critical to collision-avoidan...

Abstract This study investigated the effect of severe‐intensity exercise on neuromuscular fatigue (NMF) and torque complexity in two muscle groups of different sizes. The NMF of 11 healthy males was assessed through ma...

Wheel-legged robots offer high mobility on flat terrain and adaptability in complex environments, yet achieving stable motion under uncertain ground conditions and during height variations poses significant control chall...

Abstract Two-dimensional ferromagnetic materials hold great promise for advancing low-power, high-integrated spintronic devices due to their atomic flat surfaces and versatile interfacial modulation. However, achieving a...

Abstract The teleoperation of a 6 degrees-of-freedom (DOF) manipulator is one of the basic methods to extend people’s capabilities in the wide variety of applications. The master interface based on the force/torque (FT...

A proof is presented of how a hexagon-shaped hexacopter can be designed to keep the ability to reject disturbance torques in all directions while counteracting the effect of a failure in any of its motors. The method pro...

Abstract The primary characteristics of an electric drive include the ability to utilize the maximum torque throughout the speed range, minimal reliance on parameters, and, if feasible, the highest efficiency. This paper...

When fish turn using their caudal fins, they face a tradeoff. To turn rapidly, they must produce high torque or reduce their rotational moment of inertia or both, but these two things may pose opposite constraints. The m...

Light–matter interactions generally involve momentum exchange between incident photons and the target object giving rise to optical forces and torques. While typically weak, they become significant at the nanoscale, dr...

Abstract This study presents an integrated numerical and experimental investigation of the aerodynamic performance of the Archimedes Spiral Wind Turbine (ASWT) under wind speeds ranging from 5 to 10 m/s. The analyses wer...

"Several works have addressed the issue of fault tolerance in multirotors in case of a rotor total failure, particularly their ability to keep full independent control of attitude and altitude. It has been proven that to...

ABSTRACT Background Physical exercise is recommended for sarcopenia prevention and treatment. Patients with frailty often show poor tolerance. To achieve universal availability, electrical stimulation of skeletal muscles...

En este trabajo de tesis se proponen nuevas soluciones a dos problemáticas de control de máquinas de corriente alterna con imanes permanentes: la minimización del ripple de par y la eliminación de sensores mecánicos...
