Adaptive Collision Sensitivity for Efficient and Safe Human–Robot Collaboration

Advanced Intelligent Systems, EarlyView.
An adaptive collision‐sensitivity framework uses each robot link's effective mass to estimate contact forces online and decide when collaborative robots should stop or continue. Tested on simulated and real UR10e and simulated KUKA arms, it maintains conservative force estimates while reducing unnecessary stops and increasing task productivity. What is

Simulation of Logging-while-drilling Tool Response Using Integral Equation Fast Fourier Transform

ITM Web of Conferences, 2017
We rely on the volume integral equation (VIE) method for the simulation of loggingwhile- drilling (LWG) tool response using the integral equation fast Fourier transform (IE-FFT) algorithm to accelerate the computation of the matrix-vector product in the ...

Influence Mechanism of Structural Parameters of a Novel Sleeve‐Shaft Counterrotating Hydrodynamic Cavitation Reactor on Cavitation Characteristics and Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study systematically investigates the cavitation characteristics of a novel sleeve‐shaft counterrotating (SSCR) hydrodynamic cavitation reactor using computational fluid dynamics (CFD). Based on the RANS framework combined with the SST k–ω turbulence model and the Zwart–Gerber–Belamri cavitation model, the temporal–spatial evolution of ...

Optimized difference schemes for multidimensional hyperbolic partial differential equations

Electronic Journal of Differential Equations, 2009
In numerical solutions to hyperbolic partial differential equations in multidimensions, in addition to dispersion and dissipation errors, there is a grid-related error (referred to as isotropy error or numerical anisotropy) that affects the ...

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

The Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...
