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...

Using recordings of swell from pitch-and-roll buoys, we have reproduced the classic observations of long-range surface wave propagation originally made by Munk et al. (1963) using a triangular array of bottom pressure measurements. In the modern data, the direction of the incoming swell fluctuates by about ±10 ◦ on a time scale of one hour. But if the incoming direction is averaged over the dur...

Thermally dependent development of soybean aphid (Aphis glycines Matsumura) and common buckthorn (Rhamnus cathartica L.) were examined in growth chambers in spring 2005. Models based on ambient air temperatures for all development events were developed. Adjusted models were developed to account for heat units acquired because of solar radiation. These models were tested at field sites in Guelph...
