In contrast with the linear case, the corresponding interval of energy is finite instead of infinitesimal. Within such an interval, motion is necessarily periodic in nature, since the particle is caught inside a sink of potential. The period is given by the definite integral: [5.50]T=2M∫q...
aIf an oscillatory motion was superimposed on steady shearing,the maximum torque on the top plate during the combined motion was scarcely more then that in the steady shearing along;the minimum as considerably less.The average torque was much less in the combined motion and it is possible that ...
Generation of periodic and chaotic bursting in an excitable cell model There are interesting oscillatory phenomena associated with excitable cells that require theoretical insight. Some of these phenomena are: the threshold lo... YS Fan,TR Chay - 《Biological Cybernetics》 被引量: 162发表: 1994年 ...
14.1 Simple Harmonic Motion Oscillatory Motion Periodic motion is regular, and repeats with a characteristic time. The motions of a jump rope, a clock pendulum, and an orbiting planet are all periodic. An oscillation, or vibration, is a special type of periodic motion in which the system moves...
The force is proportional to with the proportionality constant depending on the parameters of the dumbbell-like model. The propulsion force induces a periodic oscillation of the bubble position zB (2) The bubble position zB(t) in Eq. (2) exhibits no net displacement but a periodic motion in...
In this paper is applied the impulsive force in the oscillatory motion to obtain the mathematical expression for the resultant force in the point where the tangent is unde￠ned.The impulsive forces are widely encountered in Physics, for example when a ball is struck suddenly by a bat, in the...
Breast tissue hardness can be indicative of malignancy since the stiffness or Young’s modulus of cancerous tumors is higher than that of normal tissue22,23,24. However, soft and hard tumors do not necessarily appear with different echogenicity on conventional B-mode US. Ultrasound elasticity imag...
Contactless magnetic actuation augments lobe motion into energy-efficient resonance-like oscillatory motion. The use of environmentally driven actuator materials has allowed autonomous motion generation via changes in environmental conditions. Measurement of the energy required for the differently actuated ...
In this study, an integrated 2D numerical model is developed to simulate the fluid-structure seabed interaction, which is composed of two sub-models: the flow model and seabed model. The flow model is responsible for simulating the wave motion including the wave pressure and current velocity, wh...
A fundamental aspect in the ability of this periodic eddy field to generate mean currents is the persistence of this field over a tidal cycle. The longevity of coherent eddies is, in turn, determined by the dissipation due to bottom and surface stresses, turbulence, and internal wave generation...
