Design and Performance Analysis of a Compact Series Elastic Actuator for Exoskeletons
(2022-01-01)
In this paper, a compact Series Elastic Actuator is designed and evaluated. The proposed actuator will be used to drive the joints of the modular exoskeleton for lower limbs ExoTAO (Transparent Active Orthosis), available ...
Impact dampers for controlling chaos in systems with limited power supply
(Elsevier B.V., 2005-01-21)
We investigate numerically the dynamical behavior of a non-ideal mechanical system consisting of a vibrating cart containing a particle which can oscillate back and forth colliding with walls carved in the cart. This system ...
Anesthetic Activation of Central Respiratory Chemoreceptor Neurons Involves Inhibition of a THIK-1-Like Background K(+) Current
(SOC NEUROSCIENCE, 2010)
At surgical depths of anesthesia, inhalational anesthetics cause a loss of motor response to painful stimuli (i.e., immobilization) that is characterized by profound inhibition of spinal motor circuits. Yet, although clearly ...
On an energy exchange process and appearance of chaos in a non-ideal portal frame dynamical system
(2013)
In this paper, we consider non-ideal excitation devices such as DC motors with restrictenergy output capacity. When such motors are attached to structures which needexcitation power levels similar to the source power ...
Combining active control and synchrophasing for vibration isolation of a floating raft system: An experimental demonstration
(2020-01-01)
Vibration isolation of a floating raft system typically found in a marine application is of concern in this paper. Housed on the raft are electrical motors each driving two counter rotating shafts with eccentric masses ...
A control and automation system for wave basins
(Oxford, 2013)
This paper presents the new active absorption wave basin, named Hydrodynamic Calibrator (HC), constructed
at the University of São Paulo (USP), in the Laboratory facilities of the Numerical Offshore Tank
(TPN). The square ...
ALS-linked protein disulfide isomerase variants cause motor dysfunction
(CIENCIAS, 2016)
Disturbance of endoplasmic reticulum (ER) proteostasis is a common feature of amyotrophic lateral sclerosis (ALS). Protein disulfide isomerases (PDIs) are ER foldases identified as possible ALS biomarkers, as well as ...
