A method for approximating and controlling the distributed parameter model of a MIMO chemical diffusion system
… via diffusion. More specifically, we use, as a model system, a microfluidic, in vitro assay in which a cell scaffold is bounded between two microchannels. The scaffold is taken to be a porous region through which diffusion occurs, in one dimension, from one channel to the other. In this system, …

Modeling of Nonlinear Unsteady Aerodynamics, Dynamics and Fluid Structure Interactions
We model different nonlinear systems, analyze their nonlinear aspects and discuss their applications. First, we present a semi-analytical, geometrically-exact, unsteady potential flow model is developed for airfoils undergoing large amplitude maneuvers. Towards this objective, the classical …

Micropolar Continuum Modeling of Large Space Structures with Flexible Joints and Thermal Effects: Theory and Experiment
… a geometrically reduced order (homogenized) model for a large antenna space structure with flexible joints. An energy equivalence concept is employed to find the continuum model for the system. The kinetic and strain energy expressions of the fundamental elements are found based on the …

A Whole-Farm Planning Decision Support System for Preventive Integrated Pest Management and Nonpoint Source Pollution Control
… CLIGEN (Nicks et al. 1995), and an NPS distributed-parameter model, ANSWERS (Bouraoui, 1994), databases, a database engine and utility programs. The performance of the system was analyzed and performance enhancing features were added to increase the planner's ability to find near-optimal …

ESTIMATING LOCATIONS OF SHUNT FAULTS ON DISTRIBUTION LINES
… of the line are taken into account. Distributed parameter model of the line and voltage dependent load models are used. The loads up to the fault are considered independently and the loads beyond the fault are assumed consolidated at the remote end. The load constants, describing the …

Utilization of the Distributed-Hydrology-Soil-Vegetation-Model (DHSVM) To Quantify Streamflow Changes and Slope Failure Probability Following the Snow-Talon Fire Near Lincoln Montana, USA
<p>Models are commonly used to attempt to simulate complex interactions on the landscape. Many factors such as vegetation, soils, topography, weather and disturbances can influence the hydrology of a watershed. Understanding what is influencing changes in streamflow following fire can be difficult …

Bi-layered viscoelastic model for a step change in velocity and a constant acceleration stimulus for the human otolith organs
The otolith organs are commonly modeled as a system consisting of three distinct elements, a viscous endolymph fluid in contact with a rigid otoconial layer that is attached to the skull by a viscoelastic gel layer. However, in this model the gel layer is considered as a bi-layered viscoelastic …

Mathematical modelling and optimal multivariable control of chemical processes
… work reports the developnent of a mathenatical model and distributed, multi variable computer-control for a pilot plant double-effect climbing-film evaporator. A distributed-parameter model of the plant has been developed and the time-domain model transformed into the Laplace domain. The model …

Nonlinear Dynamics of Tapping Mode Atomic Force Microscopy
A mathematical model is developed to investigate the grazing dynamics of tapping mode atomic force microscopes (AFM) subjected to a base harmonic excitation. The nonlinear dynamics of the AFM microcantilever are studied in both of the monostable and bistable phases with the microcantilever tip …

Multi-defect localization and evaluation techniques for distribution cables based on time-domain reflectometry
… comprehensive research solutions covering modeling, defect localization, severity assessment, and system implementation. To address the limitation that current cable defect reflection signal modeling mainly focuses on single-defect modeling, a general multiple-defect cable reflection signal …
