Design and Simulation of a High Frequency Exactly Solvable Chaotic Oscillator
(2012-07-27)
It has been shown that the performance of communication systems based on low dimensional chaotic systems with exact analytic solutions containing a single fixed basis function may exhibit performance comparable to that of ...
Design and Simulation of Cryogenic Test Circuits
(2016-07-27)
New technologies are being introduced in anticipation of the end of Moore’s Law, such as quantum computing, in hopes that the speed gains from the different topologies will offset the increase in size of the devices. Fast ...
Design and Synthesis of 3-Deazaaristeromycin Derivatives
(2010-12-07)
Analogs of naturally occurring nucleosides have served as structural models for the design of antitumor, antiviral, and antibacterial agents. The carbocyclic nucleosides aristeromycin and neplanocin A are two examples that ...
Design and Synthesis of AdoHcy Hydrolase Inhibitors as a Source of Antiviral Agents
(2008-05-15)
The significant antiviral properties of the carbocyclic nucleosides aristeromycin and neplanocin A have been attributed to inhibition of AdoHcy hydrolase, which in turn affects viral mRNA capping methylation. However, their ...
Design and Testing of a Gas Distribution Method for Pulsed Inductive Thrusters
(2008-12-15)
A gas distribution manifold for use in a Pulsed Inductive Thruster has been designed and tested. The Argon test gas is distributed radially outward over a flat disc from an enclosed manifold area. The manifold was designed ...
