An array of four hydrophones arranged in a symmetrical star configuration was used to measure the echolocation signals of the Atlantic spotted dolphin (Stenella frontalis) in the Bahamas. The spacing between the center hydrophone and the other hydrophones was 45.7 cm. A video camera was attached to the array and a video tape recorder was time synchronized with the computer used to digitize the ...

A video system has been developed that displays results of interactions of near-infrared radiation in the 0.78 to 1.1/xm waveband with plant leaves. The system has a video camera, video monitor, cassette player, and cassette recorder. Three examples from the literature that have been shown to affect light reflectance were demonstrated successfully with the video system: leaf water infiltration,...

Trust is the belief or confidence in someone that their recommendations will work for you, i.e. that you will like the TV-programs (or other content) that they recommend. Many systems incorporate some notion of trust. Trust is more than similarity in taste, which makes trust a broader concept than the concept of similarity used in Collaborative Filtering. This paper describes ongoing work on th...

The natural conversations and social environments of 52 undergraduates were tracked across two 2-day periods separated by 4 weeks using a computerized tape recorder (the Electronically Activated Recorder [EAR]). The EAR was programmed to record 30-s snippets of ambient sounds approximately every 12 min during participants' waking hours. Students' social environments and use of language in their...

We present the 3D Video Recorder, a system capable of recording, processing, and playing three-dimensional video from multiple points of view. We first record 2D video streams from several synchronized digital video cameras and store pre-processed images to disk. An off-line processing stage converts these images into a time-varying 3D hierarchical point-based data structure and stores this 3D ...

Recent advances in low-cost high-capacity disk drives, and low-cost high-quality video compression and decompression cards are enabling new types of digital video storage and delivery capabilities. One prominent example of this trend is the emergence of Digital (sometimes called Personal) Video Recorders (DVRs) in the home. DVRs enable the digitization, compression, storage, and time-shifted vi...
