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 ...
Experimental Design of a High Vacuum System for PUPR-MC Plasma Machine
(Polytechnic University of Puerto Rico, 2008)
In vacuum technology it is customary to divide a large pressure region (as of today, covering 16 orders of magnitude) into single, smaller regions. These divisions are somewhat arbitrary. Thus, the chemists frequently refer ...
Changing Behaviors: Re - Conceptualization of a Tutoring Center
(Polytechnic University of Puerto Rico, 2004)
The following article introduces a novel constructivist tutoring system, its origins, concepts, methods and its impact in the student population. To optimize the performance and strategic planning of the Center, a software ...
