background: about 83% of patients with breast cancer (bc) undergo radiation therapy. these patients show various degrees of mild to acute reactions during and after the completion of treatment.the aim of this study was to compare inherent radiosensitivity of gamma-irradiated g0-lymphocytes between bc patients and normal individuals using cytokinesis blocked micronucleous assay. methods: three t...

We incorporated a simulated military radio into a spoken language interface to a distributed simulation environment for military commander training. The resulting architecture bypassed the inherent problem of acoustic mismatch that arises in integrating radio output with a speech recognition front end, while at the same time preserving the realism of speech synthesis output through a military r...

A software Radio which exploits unused spectrum spaces without causing much interference to licensed spectrum users and thus optimising the use of available radio frequency is, by its virtue of its intelligence, called Cognitive Radio. Spectrum Sensing is the inherent ability of Cognitive Radio to autonomously perform required calculations and detect unused spectrum which can be used for a mult...

This paper analysis performance of energy detection technique for cognitive radio which implies spectrum sensing. Main objective is to reduce interference occur in the cognitive radio systems. Spectrum detection schemes are based on fixed threshold these are sensitive to noise; the energy detection based on dynamic threshold can improve the resistance of noise and get a good performance of dete...

Dynamic radio network level simulations for network optimization and design become more and more important in the wireless industry, because these systems become more exible, dynamic, and adaptive than they ever were before. Many proprietary discrete{event radio network simulators exist in industry and universities. These simulators are either sequential and slow or parallel, but very complex a...

Cognitive radio based networks can resolve the spectrum scarcity issues present in the current emergency communication networks. Establishing quick and secure communication between rescue team members in the disaster field is a significant task and cognitive radio MANETs are the best choice for disaster management and other emergency situations. This paper presents a scalable group key agreemen...

Audio watermarking (AW) technology is considered for stealthy information embedding directly into audio signal. Inherent in analog radiotelephone channel interferences against watermarks are analyzed. Robust encoding/decoding algorithms are presented and appropriate project of AW system named as Automatic Radio Telephone Identification System (ARTIS) is proposed. Experiment...

Cognitive radio (CR) has been an active research topic in wireless communications. In this dissertation, radio behavior and potential security threats in cognitive radio networks are investigated in order to successfully deploy CR networks and realize its benefits. We study complex CR misuse issues during its secondary access processes, including misbehavior, cheating, and attack. Different cou...

We determine the radio and optical luminosity evolutions and the true distribution of the radio-loudness parameter R, defined as the ratio of the radio to optical luminosity, for a set of more than 5000 quasars combining Sloan Digital Sky Survey optical and Faint Images of the Radio Sky at Twenty cm (FIRST) radio data. We apply the method of Efron and Petrosian to access the intrinsic distribut...
