Reinforcement learning methods as a promising technique have achieved superior results in the motion planning of free-floating space robots. However, due to increase dimension and intensification system dynamics coupling, dual-arm robots remains an open challenge. In particular, current study cannot handle task capturing non-cooperative object lack pose constraint end-effectors. To address prob...

the main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of methocel® k15, ethocel® standard 7fp premium, eudragit ® rs100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. risperidone floating tablets were formulated by wet granulati...

  Nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of...

An oral sustained-release floating tablet formulation of metformin HCl was designed and developed. Effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and HPMC-PEO polymer combination, respectively. Tablet composition was optimized by response surface methodology (RSM). Seventeen (17) trial formulations were analyzed according to Box-Behnken desi...

introduction: in order to make a dimensional proportion between human and equipment or environment, anthropometric data bank is essential. anthropometry has an important role in industrial management and ergonomic design. this information is needed to be collected regularly in every society. the purpose of this study was to determine arm length to height ratio according to gender in adults, bet...

a binuclear macrocyclic ligand containing dissimilar n(amine)2o2 and n(imine)2o2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor l1h2 with 1,3-diaminopropane. the ligand includes two propionitrile pendant arms on the amine nitrogen atoms. the homobimetallic complex [znl2zn(oac)]pf6 was synthesized by one step procedure. heterobim...

for prolonging the time that drug remains in stomach, new methods used as floating drug delivery systems, that available in various forms such as floating tablets. these systems enhance drug absorption and decrease plasma concentration fluctuations. iron deficiency and its inadequate absorption in diet are of community health problems. for prolonging the time that drug remains in stomach, new m...

Abstract When free-floating space robots perform tasks, the satellite base attitude is disturbed by dynamic coupling. The disturbance of orientation may affect communication between robot and control center on earth. In this paper, enhanced bidirectional approach proposed to plan manipulator trajectory eliminate final variation. A novel acceleration level state equation for nonholonomic problem...

To address the challenge of precise, dynamic and versatile aerial manipulation, we present an manipulation platform consisting a parallel 3-DOF manipulator mounted to omnidirectional tilt-rotor vehicle. The general modeling on floating base is presented, which motivates optimization detailed design parameters components. Inverse kinematic control coupled pose controller with compensation term, ...

Deploying large numbers of small, low-power cores has been gaining traction recently as a system design strategy in high performance computing (HPC). The ARM platform that dominates the embedded and mobile computing segments is now being considered as an alternative to high-end x86 processors that largely dominate HPC because peak performance per watt may be substantially improved using off-the...
