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.

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

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 ...

Energy analysis of a toroidal magnetohydrodynamic plasma with fluid motion
Il Nuovo Cimento D, 1991The relaxation process in an ideal magnetohydrodynamic (MHD) plasma with fluid velocity and enclosed in a toroidal vessel has been discussed. The expressions for the field parameters and the energy state of the system have been derived. The expression for the minimum energy state of the system has been deduced. An analysis of the conservation of energy

Analysis and Recognition of Facial Expression Based on Point-Wise Motion Energy
2004Automatic estimation of facial expression is an important step in enhancing the capability of human-machine interfaces. In this research, we present a novel method that analyses and recognizes facial expression based on point-wise motion energy. The proposed method is simple because we exploit a few motion energy values, which is acquired by an ...

Modeling and Analysis of a Piezoelectric Energy Scavenger for Rotary Motion Applications
Journal of Vibration and Acoustics, 2010This paper presents modeling and analysis of a piezoelectric mounted rotary flexible beam that can be used as an energy scavenger for rotary motion applications. The energy harvester system consists of a piezoelectric bimorph cantilever beam with a tip mass mounted on a rotating hub. Assuming Euler–Bernoulli beam equations and considering the effect of

Experimental analysis of internal energy transport in the presence of coherent motion
International Journal of Heat and Mass Transfer, 1998Abstract The paper presents the internal energy budget in the initial region of the slightly heated free round jet in the presence of column-mode coherent structures. The budget was obtained by the quantitative evaluation of the shares of particular streams of internal energy transported in the flow-field considered.

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.
