The dissemination of information has evolved from word-of-mouth through the printing press to the electronic communications systems of today. Although electronic media make available vast quantities of data, such systems lack the ability to present information in a personalized and useful way. Interactive computer environtments in conjunction with rich information resources are instrumental in ...

We present a new approach to the computation of an electrical field propagating in a dielectric structure. We use the Green's-function technique to compute an exact solution of the wave equation. No paraxial approximation is made, and our method can handle any kind of dielectric medium (air, semiconductor, metal, etc.). An original iterative numerical scheme based on the parallel use of Lippman...

In this thesis, I present and analyze a real-time intermediate node that promotes low latency transmission of information between two endpoints. Traditional relaying via digital decoding and retransmission has inherent time delay due to limitations in processing requirements at the transceiver, however this delay can be minimized by high speed analog amplification and forwarding rather than by ...

A system for the automatic recognition of human speech is described. A commercially available speech recognizer sees its recognition vocabulary increased through the use of virtual memory management techniques. Central to the design are issues concerning the nature of speech, its effectiveness as an isolated mode of communication with computers, and its role as a part of a multi-modal communica...

Although news headlines and research dollars have focused largely on advances made in cancer treatments, prevention researchers are hard at work developing methods to stop cancer early — before it can even be called cancer. Lippman, professor of medicine and cancer prevention and chair of the Department of Clinical Cancer Prevention at the University of Texas M. D. Ander-son Cancer Center in Ho...

Starting immunizations when girls are 9 years old and levels of antibodies are highest is the best way to prevent human papillomavirus and related cancers. About 97% of Canadians 7 to 14 years old are in school. They are already well covered by existing programs; coverage is relatively higher in primary schools than it is in high schools. Women most at risk of cervical cancer are those who drop...

this book presents a well-balanced description of the psychiatric team at work. The author has succeeded in describing the many considerations that are necessary for family diagnosis and treatment which are involved in psychiatric work with children. In a humble, critical manner Dr. Lippman distills his many years of clinical experience into principles and attitudes that are practical lessons f...

In this paper, using Monte Carlo Fortran code, we have obtained the binding energies for three different systems of diquark–antidiquark in distances from 0.01 to 15 nm. In [0.1 - 15] nm interval, we made use of Coulomb potential because in this interval, strong interaction is negligible. We have compared the binding energies of the systems with one another. The results of these comparisons...

UC San Diego Moores Cancer Center, the only NCI-designated Comprehensive Cancer Center in the San Diego region, was established in 1978. It has 13 disease teams and subspecialty cancer care programs that include surgical oncology, medical oncology, gynecologic oncology, radiation oncology, minimally invasive surgery, interventional radiology, molecular cancer imaging, palliative care, integrati...

This thesis presents a Differential Binary Phase Shift Key (DBPSK) source separation system implemented with the GNU Software Defined Radio (SDR) platform and interfaced with the existing MIT community Radio Frequency Identification (RFID) system. Source separation, well studied in the theoretical signal processing setting, presents an opportunity to achieve higher throughput in a practical SDR...
