Material damping for lumped‐parameter models of foundations
Earthquake Engineering & Structural Dynamics, 1994AbstractIn foundation dynamics two mechanisms of energy dissipation exist, wave radiation and material damping. Elastic continuum models of the soil capture only the radiation effect. To incorporate material damping, use is made of the fact that the dynamic‐stiffness relationships of all elastic foundations may be simulated by discrete assemblages of ...

Lumped-parameter model for in vivo cochlear stimulation
IEEE Transactions on Biomedical Engineering, 1993This paper presents a lumped-parameter model that stimulates the in vivo electrical properties of a guinea pig cochlea implanted with a multielectrode stimulating array. A basic model of the low-frequency electroanatomy in a normally functioning guinea pig cochlea is developed by adding critical membrane capacitances to Strelioff's resistive network ...

A lumped-parameter model for infiltration
Journal of Hydrology, 1982Abstract A dynamical lumped-parameter model for vertical infiltration is presented. The model is based on a rough spatial discretization of the partial differential equation of water movement in unsaturated soil. The aim of the model is to describe the infiltration in a catchment under highly variable rainfall rates. The ponding is connected with the

Lumped parameter model of cardiovascular-respiratory interaction
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013The aim of this work was to develop a lumped parameter model of the cardiovascular system and to couple it with a model of respiratory mechanics. In comparison to existing models, modifications and additions have been implemented to include a model of the upper limb vasculature employing the electrical analogy of hemodynamic variables.

LUMPED PARAMETER MODELING OF THE LITHO CELL
IFAC Proceedings Volumes, 2006Abstract Litho cells are the most expensive equipment in a wafer fab. To support decision-making on this equipment, accurate simulation models for throughput and flow time are helpful. The simulation models that are typically developed incorporate various shop floor details.

A Lumped Parameter Mathematical Model of the Splanchnic Circulation
Journal of Biomechanical Engineering, 1992A lumped parameter mathematical model to describe the propulsion of blood in the splanchnic circulation was developed by integrating the principles of mechanics and physiology. A set of governing equations by derived by specifically considering the contractility of the portal vein, hepatic vein, liver sinusoids, and of the draining lymphatics.

A lumped parameter model of the single free-flooded ring transducer.
Journal of the Acoustical Society of America, 2017A free-flooded ring (FFR) transducer can generate low-frequency sound in a small device and has a wide operating frequency bandwidth. Many studies have been performed that can predict the characteristics of an FFR transducer using analytical techniques ...

Use of Lumped Parameter Modeling for Geothermal Engineering
Proceedings of SPE California Regional Meeting, 1983Abstract The theory and algorithm are presented for the implementation of a lumped parameter approach for geothermal reservoir simulation in the early stages of the development of a geothermal field. The model can be applied to all types of geothermal systems: all-liquid, all-steam, or two-phase.
