Static Stability Analysis of Planar Grasps by Multiple Fingers with Redundant Joints

open access: yesActuators
This paper deals with static stability in planar grasps of an object by multiple fingers. Differently from previous research, we focus on the case that each finger has redundant links and joints.

Uma definição natural de energia cinética e potencial em termodinâmica

open access: yesRevista Brasileira de Ensino de Física
Na tentativa de tornar a termodinâmica mais familiar e sem violação do seu formalismo, define-se a partir de expressão do diferencial da energia, já incorporando as conseqüências da 2 Lei, o diferencial da energia cinética como associado às variações de ...

The Casimir Energy in a Separable Potential

open access: yes, 1999
The Casimir energy is the first-order-in-\hbar correction to the energy of a time-independent field configuration in a quantum field theory. We study the Casimir energy in a toy model, where the classical field is replaced by a separable potential.

Effect of High Pressure on the Solidification of Al–Ni Alloy

open access: yesCrystals, 2021
The effect of high pressure on the microstructure of hypo-peritectic Al–38wt.%Ni alloy was studied. The results show that Al3Ni and Al3Ni2 phases coexist at ambient pressure. However, it becomes a typical hyper-eutectic microstructure when synthesized at

Verification of a Stiffness-Variable Control System with Feed-Forward Predictive Earthquake Energy Analysis

open access: yesSensors, 2021
Semi-active isolation systems with controllable stiffness have been widely developed in the field of seismic mitigation. Most systems with controllable stiffness perform more robustly and effectively for far-field earthquakes than for near-fault ...

Evaluation of Exchange-Correlation Energy, Potential, and Stress

open access: yes, 2001
We describe a method for calculating the exchange and correlation (XC) contributions to the total energy, effective potential, and stress tensor in the generalized gradient approximation.

Saddles on the potential energy landscape of a Lennard-Jones liquid [PDF]

open access: yes, 2000
By means of molecular dynamics simulations, we study the stationary points of the potential energy in a Lennard-Jones liquid, giving a purely geometric characterization of the energy landscape of the system.
