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 ...
Automation of Plasma Diagnostics at Polytechnic University of Puerto Rico
(Polytechnic University of Puerto Rico, 2008)
This work presents an ongoing effort to develop an automatic measurement system for plasma diagnostics at the Plasma Engineering Laboratory of Polytechnic University of Puerto Rico, along with an example of its operation. ...
High Density Plasma Nitriding on Stainless Steel Alloys at PUPR-MC Plasma Machine
(Polytechnic University of Puerto Rico, 2008)
A novel method of nitriding at high current levels at Polytechnic University of Puerto Rico Mirror Cusp plasma machine (PUPR-MC) has been performed. Nitrogen ions implantation or plasma nitriding increases the hardness at ...
Mass Spectrometric Study of Various Coated Targets Utilizing PUPR-MC Plasma Machine for NASA Solar Probe Space Mission
(Polytechnic University of Puerto Rico, 2008)
The NASA Solar Probe Space Mission will be a historic operation, flying for the first time into one of the last unexplored regions of the solar system, the Sun's atmosphere or corona; hopefully revolutionizing our knowlege ...
