This paper proposes a new multicast transport protocol, called the Enhanced Communications Transport Protocol (ECTP). The proposed protocol is currently being standardized in the ITU-T SG7 and ISO/IEC JTC 1/SC 6. The ECTP is designed to support tightly controlled multicast connections. The sender is at the heart of one-to-many multicast group communications. The sender is responsible for overal...

Several antimalarials can cause significant prolongation of the electrocardiograph QT interval, which can be associated with an increased risk of potentially lethal ventricular arrhythmias. High doses of artemether and artemotil have been associated with QT prolongation in dogs, raising the possibility of a class effect with the artemisinin derivatives. Serial electrocardiograms were recorded, ...

This paper will focus on improving the performance of orthogonal frequency division multiplexing (OFDM) in Rayleigh fading environments. The proposed technique will use a previously published method that has been shown to improve OFDM performance in independent fading, based on ordered sub-carrier selection. Then, a simple non-iterative method for finding the optimal bit-loading allocation was ...

Radio frequency identification (RFID) has received much attention both in industry and academia in recent years. To this extent, the international standards group, ISO/IEC JTC 1/SC 31, is in the midst of standardization activity to define the security extension to the EPCglobal Generation 2 (Gen2) ultra high frequency (UHF) air interface protocols for secure RFID communications. In this paper, ...

The Dual Nonlinear Correlation (DNC) model implemented by an optoelectronic joint transform correlator (JTC) (Millán et al., Dual Nonlinear Correlation in Optical Pattern Recognition I, Óptica Pura y Aplicada 38, núm. 2, 75-83, 2005) provides a pattern recognition system with adjustable discrimination capability (DC). By varying the values of two real parameters (L and M) in the DNC we obtain e...

We investigated the effects of prolonged repolarization induced by slowed inactivation of Na+ channel on adrenaline-induced arrhythmias in halothane anesthetized, closed-chest dogs. We used sea anemone toxins (ATX-II and Anthopleurin-A) to prolong ventricular repolarization and examined their effects on adrenaline arrhythmias. Sea anemone toxins prolonged the QTc- and JTc-intervals (P<0.01), bu...

In this paper, we propose a new technique for rotation invariant recognition and tracking of the face of a target person in a given scene. We propose an optimized method for face tracking based on the Fringe-adjusted JTC architecture. To validate our approach, we used the PHPID data base containing faces with various in-plane rotations. To enhance the robustness of the proposed method, we used ...

This study analyzes a series of crimes committed by sexual offenders and a series committed by non-sexual offenders. Subjects chosen for the study were seven sexual offenders (Test Group) and twelve offenders with non-sexual crimes (Control Group). Test data were selected from the Minnesota Predatory Offender Registry. Control group data were randomly selected from data provided with the crime ...

Biometric Identity Assurance Services, or BIAS, is a cooperative standards project between the International Organization for Standardization / International Electrotechnical Commission Joint Technical Committee 1 Subcommittee SC 37 (ISO [8]/IEC JTC 1 SC 37) and the Organization for the Advancement of Structured Information Standards (OASIS) BIAS Technical Committee (TC). BIAS originated as a c...
