Memory effects in superfluid vortex dynamics
(Springer/Plenum Publishers, 2004-11)
The dissipative dynamics of a vortex line in a superfluid is investigated within the frame of a non-Markovian quantal Brownian motion model. Our starting point is a recently proposed interaction Hamiltonian between the ...

Self-lubricating Cu-MWCNT coatings deposited from an ecofriendly glutamate-based electrolyte
(Elsevier Science SA, 2020-04)
Self-lubricating coatings have been studied for a long time due to their convenience compared to systems which need periodic lubrication. For this reason, Cu-CNT composite coatings with high wear resistance and low coefficient ...
Bayesian inference of constitutive parameters from video data of the impact dynamics of a ball
(Springer, 2020-04-01)
The trajectory of a ball impacting with an angle on a rigid boundary is recorded with a high-speed camera and the dynamics is reconstructed in a computer. Several experiments are carried out in order to obtain statistical ...
Stress reduction in the residual limb of a transfemoral amputee varying the coefficient of friction

Dynamic Coefficients of Finite Length Journal Bearing. Evaluation Using a Regular Perturbation Method
(Pergamon-Elsevier Science Ltd, 2019-02)
A set of simple expressions is deduced for static and dynamic parameters associated to hydrodynamic journal bearings (JB). The behavior of this system is governed by two dimensionless numbers, the aspect ratio, L/D, and ...
Characterization and frictional behavior of nanostructured Ni-W-MoS2 composite coatings
(Elsevier Science Sa, 2009-09)
Ni-W-MoS2 composite coatings were obtained by pulse plating from a Ni-W electrolyte containing suspended MoS2 particles. The coating composition, morphology, crystalline structure, microhardness and frictional behavior ...
Assessment of gas-particle flow models for pseudo-2D fluidized bed applications
(Taylor & Francis, 2018-04)
The aim of this work is to provide more insight into the general modeling criteria for simulating pseudo-2D bubbling fluidized beds. For this purpose, two experimental-based problems are studied. First, a fluidized bed ...
