Neither the effects of repetitive swells on metal-oxide varistors, nor the natural occurrence of swells had been documented in the literature. The paper briefly described a laboratory system capable of generating arbitrary swells and applying them to test varistors. A statistical experiment on five lots of varistors was performed and preliminary results reported. Effects of amplitude, duration,...

Swelling soil leads to many types of constructional damages, deformations, and failures in the constructions’ roads, shoulders, foundations. Depending on amount swell, they can be insignificant, moderate, or massive. This paper presents a method for swelling stabilization by adding rice husk powder (RHP) variable percentages 0, 5, 10, 15, 20, 25 weight dry soil. The properties were investigated...

An overview is given of current operational methods for retrieving two-dimensional ocean wave spectra from near real-time ERS-1 SAR wave mode (SWM) imagette spectra. The SWM data quality and performance of the WASAR algorithm are assessed. Sensitivity analyses and validation studies are performed using two-dimensional NOAA buoy data as well as TOPEX and ERS-1 altimeter-derived signiicant wave h...

This paper elucidates the methodology of applying artificial neural network model (ANNM) to predict the percent swell of calcitic soil in sulphuric acid solutions, a complex phenomenon involving many parameters. Swell data required for modelling is experimentally obtained using conventional oedometer tests under nominal surcharge. The phases in ANN include optimal design of architecture, operat...

Thin polydimethylsiloxane (PDMS) films are frequently used in "lab on a chip" devices as flexible membranes. The common solvent used to dilute the PDMS for thin films is hexane, but hexane can swell the underlying PDMS substrate. A better solvent would be one that dissolves uncured PDMS but doesn't swell the underlying substrate. Here, we present protocols and spin curves for two alternatives t...
