Avalanches in fine, cohesive powders
(American Physical Society, 2000)
We have investigated the onset of avalanches in fine, cohesive granular materials. In our experiments shear stress is generated by tilting an initialized bed of powder and increasing the angle of tilt until the powder ...

Fast full-wave analysis of multistrip transmission lines based on MPIE and complex image theory
(Institute of Electrical and Electronics Engineers, 2000)
The mixed-potential electric-field integral equation is used in conjunction with the Galerkin's method and complex image theory for analyzing a transmission line with multiple strips embedded in different layers of a ...

An automated apparatus for measuring the tensile strength and compressibility of fine cohesive powders
(American Institute of Physics, 2000)
This paper describes an apparatus based on a novel use of a powder bed, whereby the relationship between consolidation stress, tensile strength, and free volume of fine powder is measured. The powder to be tested is first ...

Dynamics of EHD Laminar Plumes: scaling analysis and integral model
(AIP Publishing, 2000)
In this paper electrohydrodynamic (EHD) plumes are examined in the region far from the injecting electrode and the collector plate, for both two-dimensional and axisymmetric geometries. The relative importance of the ...

CMOS design of a current-mode multiplier/divider circuit with applications to fuzzy controllers
(Springer, 2000)
Multiplier and divider circuits are usually required in the fields of analog signal processing and parallel-computing neural or fuzzy systems. In particular, this paper focuses on the hardware implementation of fuzzy ...
