Fundamental Research on Absorbing Energy from Ocean Waves (2nd report)

2nd Annual Report on Strees

Report from the 2nd Workshop on Extremely Large Databases

The complexity and sophistication of large scale analytics in science and industry have advanced dramatically in recent years. Analysts are struggling to use complex techniques such as time series analysis and classification algorithms because their familiar, powerful tools are not scalable and cannot effectively use scalable database systems. The 2 Extremely Large Databases (XLDB) workshop was...

Scientific report “2nd TYC Conference: Charge Transfer for Energy Applications”

Charge transfer underlies the function of many devices ranging from transistors to light-emitting diodes, and from solar to biofuel cells. It is often the limiting factor for the performance of these devices. As such it is absolutely vital to understand the mechanism, thermodynamics and kinetics of this important physical process on a molecular level. Although the time and length scales of the ...

Characterizing Dangerous Waves for Ocean Wave Energy Converter Survivability

Ocean Wave Energy Converters (OWECs) operating on the water surface are subject to storms and other extreme events. In particular, high and steep waves, especially breaking waves, are likely the most dangerous to OWECs. A method for quantifying the breaking severity of waves is presented and applied to wave data from Coastal Data Information Program station 139. The data are wave height and len...

Dynamic radiation force of acoustic waves on absorbing spheres

We present a theoretical study on how dynamic radiation force of acoustic waves actuates on absorbing spheres. We consider the radiation force is generated by the difference-frequency component of a bichromatic plane wave in a lossless fluid. We analyze the spectrum of the dynamic radiation force for polymethymethacrylate (lucite) and polyethylene spheres. Results reveal that absorption cause t...
