Performance trade-off analysis in bidirectional network beamforming.
(2011-10-01)This research examines a two-way relay network consisting of two transceivers and multiple parallel relays, which are equipped with single antennas and operate in a halfduplex mode. In this system, the two transceivers ... -
Perpetually playing physics
(2019-08-01)Here we discuss ideas of reinforcement learning and the importance of various aspects of it. We show how reinforcement learning methods based on genetic algorithms can be used to reproduce thermodynamic cycles without prior ... -
Petri net modeling of fault analysis for probabilistic risk assessment
(2013-04-01)Fault trees and event trees have been widely accepted as the modeling strategy to perform Probabilistic Risk Assessment (PRA). However, there are several limitations associated with fault tree/event tree modeling. These ... -
The Pharmacological Characterization of Hco-UNC-49, a GABA-gated Chloride Channel from the Parasitic Nematode Haemonchus contortus
(2010-08-01)Compared to mammals, nematodes appear to exhibit a unique GABAergic nervous system. Haemonchus controtus is a parasitic nematode that infects ruminants worldwide. Hco-UNC-49 is a H. contortus GABA-gated chloride channel ... -
