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 ...

Dynamic Analysis of Hula Hoop Motion and Optimized Energy Harvest Circuit
Volume 8: 22nd Reliability, Stress Analysis, and Failure Prevention Conference; 25th Conference on Mechanical Vibration and Noise, 2013The nonlinear dynamics of hula hoop motion is deciphered in this study by nonlinear dynamic modeling techniques to find solution and stability analysis. This is different from the previous study [1], where a homotopy method is employed. The analysis results are capable of transforming linear reciprocating motion into rotational motion.

An energy analysis of the prescribed motion of an oscillator
Journal of Applied Mathematics and Mechanics, 2001Abstract The energy consumption in the problem of the prescribed periodic motion of an oscillator is analysed. Since the solution of this problem by actuators involves extra weight and hence additional energy is required, it is proposed to use springs with linear or non-linear characteristics for local energy storage.
