Inertial Effects in the Response of Viscous and Viscoelastic Fluids
Physical Review Letters, 2005We consider the effect of inertia on the high frequency response of a general linear viscoelastic material to local deformations. We calculate the displacement response and correlation functions for points separated by a distance r. The effects of inertia and incompressibility lead to anticorrelations in the correlation or response functions, which ...

Altered inertial response of generic degrees of freedom
The Journal of Chemical Physics, 2004A method to alter the inertial response of generic degrees of freedom is presented. A Hamiltonian acts on the inertial response of a set of independent configurational observables by the introduction of a kinetic bias. The method finds its natural application in reducing the spreading of arbitrary modes in a complex system.

Response of a Beam on an Inertial Foundation to a Traveling Load
AIAA Journal, 1977The response of a Bernoulli-Euler beam supported by a Winkler-type elastic foundation with inertia and subjected to a moving load is investigated. Steady-state solutions are determined for an undamped and linearly damped beam-foundation system. The effects on the response of load velocity, foundation mass, and damping are studied.

2016 North American Power Symposium (NAPS), 2016
The frequency regulation capability of a wind power plant plays an important role in enhancing frequency reliability especially in an isolated power system with high wind power penetration levels. A comparison of two types of inertial control methods, namely frequency-based inertial control (FBIC) and stepwise inertial control (SIC), is presented in ...

Deriving inertial response from a non-inertial PV system for frequency regulation
2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012As photovoltaic (PV) penetration is gaining its momentum in the recent past, grid codes will demand contribution by PV systems to frequency regulation. This paper presents an investigation into the frequency regulation aspect of photovoltaic systems. An inertial response from photovoltaic system is derived by making it to work away from MPPT point of ...

Inertial Response of Electrical Power Systems
2020 IEEE Electric Power and Energy Conference (EPEC), 2020Following loss of generation events and during the period prior to the deployment of automatic generation control, the stabilization of system frequency above load shedding levels rests solely on the system inertia, self regulation, and governor response. This paper focuses on system inertia.

Active stiffness of the ankle in response to inertial and elastic loads
Journal of Electromyography and Kinesiology, 2004Effective stiffness of the musculoskeletal system was examined as a function of the characteristics of an external load. Thirteen healthy subjects provided active contraction of the ankle plantarflexion musculature in a neutral ankle posture to support an external load.

The stress of the wind exerted over the sea surface is the prime driving force of circulation in the coastal ocean. Yet, as already pointed out in the previous chapter, wind action only affects directly through internal friction a surface layer usually much thinner than the total water column.

Inertial and frequency response of microgrids with induction motors
2016 IEEE 17th Workshop on Control and Modeling for Power Electronics (COMPEL), 2016This paper presents an operation strategy for microgrids to provide inertial and frequency response using the kinetic energy stored in their induction motor (IM) loads. This is achieved by actively controlling the microgrid electrical frequency in systems that connect to the network through an asynchronous link.
