The objectives of this effort are to determine the extent to which Doppler radar techniques can be exploited for both qualitative and quantitative nearshore measurement applications. Of particular interest are estimates of surf zone location, extent, surface currents, and wave parameters. To date, optical (video) techniques have been the primary remote sensing technology for these applications....

This study examines the phenomenon of cyberbullying on Facebook and how it is related to school bullying among secondary school students in Singapore, aged 13–17. We also focus on generic use of Facebook and risky Facebook behaviors as the predictors of cyberbullying and victimization on Facebook. 1676 secondary students, from two secondary schools, participated in a pen and paper survey. The f...

It is at times important to detect human presence automatically in secure environments. This needs a shape recognition algorithm that is robust, fast and has low error rates. The algorithm needs to process camera images quickly to detect any human in the range of vision, and generate alerts, especially if the object under scrutiny is moving in certain directions. We present here a simple, effic...

[1] Absolute and relative diffusivity are measured on a rip-channeled beach using 30 position-tracking drifters released in clusters (4–12 drifters) deployed on 7 days with different wave forcing and tidal elevations at Sand City, Monterey Bay, California. Diffusivity and dispersion were found to be larger on days with rip current flow patterns and larger waves. Rip currents cause material to d...
