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 ...
Tip Optimization for Near-Field Scanning Optical Microscopy by Laser-Heated Pulling
(Polytechnic University of Puerto Rico, 2005)
The ability to manufacture reproducible and low-cost probe tips is critical for the improvement of near-field scanning optical microscopy as both the resolution and efficiency of the apparatus depend on the tip's geometrical ...
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 ...
Design of an Automation and Control System for PUPR-MC Plasma Machine
(Polytechnic University of Puerto Rico, 2008)
The automation of Polytechnic University of Puerto Rico Mirror-Cusp (PUPR-MC) plasma machine is part of the work performed by the Plasma Engineering Laboratory in the experiments of the NASA Solar Probe Mission Thermal ...
Wireless LANs
(Polytechnic University of Puerto Rico, 2000-12)
There are three digital wireless technologies: CDMA (Code Division Multiple Access), TDMA (Time Division Multiple access), and GSM (Global System for Mobile Communication). Ethernet is a standard LAN protocol that operates ...
Cryptography and Steganography: Security in Electronic Transactions
(Polytechnic University of Puerto Rico, 2000-12)
A new use for two ancient arts and sciences; Cryptography and Steganography are now as useful as they were thousands of years ago. The digital communication security rests mainly on the developments of these two methodologies ...
