Predicting Nitrate Concentration in Groundwater Resources using Lumped-Parameter Model: Case Study in Qazvin Plain

open access: greenسلامت و محیط, 2016
Background and Objective: The concentration of nitrate, factors affecting the balance sheet, and the changes in an aquifer is of utmost importance. Because modeling is an efficient method to predict the concentration of ions in water resources, in this ...

A coupled radial-torsional lumped parameter model of rubber bushing for multibody dynamic simulations [PDF]

open access: yesMATEC Web of Conferences, 2023
Many constitutive models’ finite element (FE) models and lumped parameter models included have been presented for rubber bushings. In general, the FE models cannot be directly used in mechanical multibody systems with bushings, and the lumped parameter ...

Estimation of groundwater age distributions from hydrochemistry: comparison of two metamodelling algorithms in the Heretaunga Plains aquifer system, New Zealand [PDF]

open access: yesHydrology and Earth System Sciences, 2023
Groundwater age or residence time is important for identifying flow and contaminant pathways through groundwater systems. Typically, groundwater age and age distributions are inferred via lumped parameter models based on measured age tracer ...

Experimental and Theoretical Study of Surge Behavior in a Boil-Off Gas Centrifugal Compressor on an LNG Carrier

open access: yesEnergies, 2022
In this study, we conducted experiments and numerical analysis on a 270 kW industrial-scale centrifugal compressor used in the fuel supply system of an LNG carrier in order to improve the lumped-parameter surge model by considering the viscosity in the ...

Kelvin-Voigt lumped parameter models for approximation of the Power-law Euler-Bernoulli beams

open access: yesAlexandria Engineering Journal, 2023
The purpose of this research is to initiate an investigation of the nonlinear material strain-rate damping effects on the amplitude and frequencies of some Euler-Bernoulli Beams. It is well known that the dynamic behaviors of most heat-treated metals can

Topological semantics for lumped parameter systems modeling [PDF]

open access: yesAdvanced Engineering Informatics, 2019
Abstract Behaviors of many engineering systems are described by lumped parameter models that encapsulate the spatially distributed nature of the system into networks of lumped elements; the dynamics of such a network is governed by a system of ordinary differential and algebraic equations. Languages and simulation tools for modeling such

Lumped parameter model based surgical planning for CABG

open access: yesMedicine in Novel Technology and Devices, 2019
The current 3D CABG model is time consuming, a lumped parameter CABG model may solve this problem. A coronary lumped parameter model without stenosis and graft was constructed. The stenosis resistance was calculated and graft model was constructed. After
