Depression Severity Is Related to Less Gross Body Movement: A Motion Energy Analysis
Psychopathology, 2021Psychomotor retardation is a well-known clinical phenomenon in depressed patients that can be measured in various ways. This study aimed to investigate objectively measured gross body movement (GBM) during a semi-structured clinical interview in patients with a depressive disorder and its relation with depression severity. A total of 41 patients with a

Energy analysis of wave motions in the lamb problem
Soviet Applied Mechanics, 1981The problem of the motion of an elastic halfspace (Lamb problem) excited at the surface (x-y plane) by a harmonic normal force is studied. Emphasis is layed on analyzing the partition of the energy among the different wave modes (longitudinal, transverse, Rayleigh) thus generated.

Motion-mode energy method for vehicle dynamics analysis and control
Vehicle System Dynamics, 2013Vehicle motion and vibration control is a fundamental motivation for the development of advanced vehicle suspension systems. In a vehicle-fixed coordinate system, the relative motions of the vehicle between body and wheel can be classified into several dynamic stages based on energy intensity, and can be decomposed into sets of uncoupled motion-modes ...

Nonlinear analysis of motion energy calculations in cat visual cortex
Proceedings of the Fifteenth Annual Northeast Bioengineering Conference, 2003The authors have applied a set of one- and two-bar tests to directionally selective (DS) complex cells in the cat's striate cortex, and also to a motion energy model. Both one- and two-bar responses of DS complex-cells match closely the unidirectional output of the motion energy model, which depends on a squaring operation.

Biological Cybernetics, 1991
Energy filters are tuned to space-time frequency orientations. In order to compute velocity it is necessary to use a collection of filters, each tuned to a different space-time frequency. Here we analyze, in a probabilistic framework, the properties of the motion uncertainty.

Human motion energy harvesting: numerical analysis of electromagnetic swing-excited structures
Smart Materials and Structures, 2016Energy harvesting from human motion has constantly attracted scientific interest over recent years. A location where a harvesting device can easily and unobtrusively be integrated is the shoe sole, which also protects the device from exterior influences.

Analysis of induced voltage for ferrohydrodynamic energy harvester using sloshing motion
2015 18th International Conference on Electrical Machines and Systems (ICEMS), 2015Energy Harvester is a very useful device to a low power generation. Here, we investigates the implementation of this device which uses sloshing motion of ferrofluid to generate electromotive force(EMF). Ferrofluid is often used on harvester system as it has magnetic properties such as soft iron. Also, there is liquidity in ferrofluid material.

Feature-Adaptive Motion Energy Analysis for Facial Expression Recognition
2007In this paper, we present a facial expression recognition method using feature-adaptive motion energy analysis. Our method is simplicity-oriented and avoids complicated face model representations or computationally expensive algorithms to estimate facial motions.

Energy Analysis of Flow Induced Harmonic Motion in Blood Vessel Walls
Cardiovascular Engineering, 2005Energy is transferred between the flowing blood and the vessel walls during pulsatile blood flow (a normal pulse cycle) resulting in storage and dissipation of elastic energy. This allows the elastic and muscular arteries to act as an auxiliary pump to propel the blood fluid forward during systole and maintain a basal blood pressure during diastole ...
