Acceleration-induced nonlocality: kinetic memory versus dynamic memory [PDF]

, 2001
The characteristics of the memory of accelerated motion in Minkowski spacetime are discussed within the framework of the nonlocal theory of accelerated observers. Two types of memory are distinguished: kinetic and dynamic.

How granular materials deform in quasistatic conditions [PDF]

, 2009
Based on numerical simulations of quasistatic deformation of model granular materials, two rheological regimes are distinguished, according to whether macroscopic strains merely reflect microscopic material strains within the grains in their contact ...

DETERMINATION OF DYNAMIC CHARACTERISTICS OF TECHNOLOGICAL EQUIPMENT ORGANS

Авіаційно-космічна техніка та технологія, 2019
The production of complicated profile parts for aerospace technology is carried out by processing along spatial paths. The nature of the movement of each axis of the equipment is dynamic and unsteady-state.

An Automated Rectification Method for Unmanned Aerial Vehicle LiDAR Point Cloud Data Based on Laser Intensity

Remote Sensing, 2019
Point cloud rectification is an efficient approach to improve the quality of laser point cloud data. Conventional rectification methods mostly relied on ground control points (GCPs), typical artificial ground objects, and raw measurements of the laser ...

Influence of functional rider and horse asymmetries on saddle force distribution during stance and in sitting trot [PDF]

, 2019
Asymmetric forces exerted on the horse's back during riding are assumed to have a negative effect on rider–horse interaction, athletic performance, and health of the horse.

Investigation on energetic optimization problems of stochastic thermodynamics with iterative dynamic programming

, 2009
The energetic optimization problem, e.g., searching for the optimal switch- ing protocol of certain system parameters to minimize the input work, has been extensively studied by stochastic thermodynamics.

A Surrogate Model of Gravitational Waveforms from Numerical Relativity Simulations of Precessing Binary Black Hole Mergers [PDF]

, 2017
We present the first surrogate model for gravitational waveforms from the coalescence of precessing binary black holes. We call this surrogate model NRSur4d2s. Our methodology significantly extends recently introduced reduced-order and surrogate modeling

An optimal stepwise inertial control strategy for wind turbines based on improved fuzzy adaptive control

Zhejiang dianli
Conventional stepwise inertial control （SIC） is decoupled from grid frequency， which limits the real-time frequency perception of wind turbines and may lead to severe secondary frequency drop （SFD）.

Detection of postural sway abnormalities by wireless inertial sensors in minimally disabled patients with multiple sclerosis: a case–control study

Journal of NeuroEngineering and Rehabilitation, 2015
Common clinical neurological exams can be insensitive to balance and mobility impairment at the early stages of multiple sclerosis (MS) and may not correspond with patient reports.

Numerical Study of Drop Motion on a Surface with Wettability Gradient and Contact Angle Hysteresis

, 2013
In this work, the motion of a 2-D drop on a surface with given wettability gradient is studied numerically by a hybrid lattice-Boltzmann finite-difference method using the multiple-relaxation-time collision model.
