Water Quantity and Quality Issues in El Paso Del Norte Region
(Polytechnic University of Puerto Rico, 2005)
The El Paso del Norte Region faces challenges in the administration of its water resources in the way water is managed due to conflicts with different political jurisdictions and existing laws governing water management ...
Power Electronics Research Experience for Undergraduates
(Polytechnic University of Puerto Rico, 2004)
On the first half of the 20th century many of the electronic devices and machinery used were very expensive, inefficient, unreliable, and robust. With revolutionary advances in semiconductor technology much of these barriers ...
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 ...
