The authors develop an electrical model of a soil moisture sensor using data collected from an automated data acquisition system. The model developed, which is useful in expediting sensor design, is capable of predicting the responses of the sensor at different moisture conditions and at different frequencies. Comparison of the model and experimental data(More)
Two experiments were conducted to test the hypothesis that animated representations of vector fields are more effective than common static representations even for steady flow. We compared four flow visualization methods: animated streamlets, animated orthogonal line segments (where short lines were elongated orthogonal to the flow direction but animated in(More)
We discuss the use of homogenization techniques to derive approximate models with simple geometry for physical models of grids and trusses which have a complex geometry that gives rise to computational diiculties. Our presentation is in the context of inverse or parameter estimation problems for composite material structures with unknown characteristics(More)
