Hyperbolic, Ultrastatic Wormhole Solution to the Vacuum Effective Gravity Equations in Randall Sundrum Brane World
(Polytechnic University of Puerto Rico, 2005)
We provide a traversable wormhole solution to the effective vacuum gravity equations in Randall Sundrum brane world scenario. We argue that graviton effects from the bulk spacetime can stabilize the wormhole"s throat against ...
Smart Antenna Performance Simulation in Multipath Propagation Environment
(Polytechnic University of Puerto Rico, 2008)
This paper presents the effect of multipath propagation on the performance of smart antenna. The influence of the correlation between the source multipath components on the uplink beam pattern shape, as well as the resulting ...
Plasma Gas Identification Using the Single Langmuir Probe
(Polytechnic University of Puerto Rico, 2008)
A novel method to identify mass composition of plasmas was discovered at Polytechnic University of Puerto Rico Mirror Cusp (PUPR-MC) plasma machine using a Single Langmuir probe characteristic. This is a comparative method ...
Are you making good decisions?
(Polytechnic University of Puerto Rico, 2004)
Due to the wide array of choices that modern society has at its disposal, decision making has become an integral part of our daily routines. Because of that, most of the time, the potential repercussions associated with ...
