The Rainfall-Response Aquifer and Watershed Flow Model (RRAWFLOW) is a lumped-parameter model that simulates streamflow, spring flow, groundwater level, or solute transport for a measurement point in response to a system input of precipitation, recharge, or solute injection. I introduce the first version of RRAWFLOW available for download and public use and describe additional options. The open...

Widely used approaches to modeling random effects and extracting random parameters in matching-critical circuits are based upon models derived under the widely accepted premise that distributed parameter devices can be modeled with lumped parameter models. In this paper, a new stochastic approach based upon a distributed parameter model is presented that offers improvement in predicting the eff...

Macroscopic, microscopic, and mesoscopic lumped-parameter models of shape memory alloy wires subjected to axial loads and new flutter prediction methods of a steady and a non-steady aeroelastic system will be presented with some comparison to previous studies.

In the paper design of control processes for class of distributed parameter systems is presented. Controlled system is interpreted as lumped-input/distributed-output systems with dynamics modelled by finite element method. Schemes of distributed parameter control loops are arranged in software environment Distributed Parameter Systems Blockset for MATLAB & Simulink, which is third-party MathWor...

To address the issue of computational efficiency related to modelling blood flow in complex networks, we derive a family nonlinear lumped-parameter models for compliant vessels departing from well-established one-dimensional model. These 0D must preserve important properties original 1D model: nonlinearity pressure-area relation and pressure-dependent parameters characterizing models, resistanc...
