—In this paper, we present a practical and provably secure two-way wireless communication scheme in the presence of a passive eavesdropper. The scheme implements a randomized scheduling and power allocation mechanism, where each legitimate node transmits in random time slots and with random transmit power. Such randomization results in ambiguity at the(More)
2-([1,2,4]Triazolo[4,3-a]quinoxalin-4-ylthio)acetic acid hydrazide (10) was used as a precursor for the syntheses of novel quinoxaline derivatives with potential anticonvulsant properties. The newly synthesized compounds have been characterized by IR, (1)H NMR, and mass spectral data followed by elemental analysis. The anticonvulsant evaluation was carried(More)
Chemical pre-precipitation becomes one of the best options of chemical treatment of sewage. In the present study, chemical pre-precipitation was processed via swirl flow hydraulic clari-flocculators, which were investigated using the steady state analysis versus the simulation using of computational fluid dynamics (CFD) software for the optimal model(More)
