Basic Plasma Diagnostics: Probes and Analyzers
(Polytechnic University of Puerto Rico, 2008)
What is plasma? Plasma is the fourth state of matter. Plasma are conductive assemblies of charged particles, neutrals and fields that exhibit collective effects. Plasma is profoundly influenced by the electrical interaction ...
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 ...
Reflexión sobre los cambios recientes en el Departamento de Ciencias Geomáticas de Ia Universidad Politécnica de Puerto Rico

El objetivo del presente escrito es presentar una recopilación de los eventos y datos relevantes que impulsaron el cambio de nombre del Departamento de Agrimensura y Cartografía a Departamento de Ciencias Geomáticas y los ...
Bibliografía selecta: Recursos de información en Ciencias Geomáticas
(Polytechnic University of Puerto Rico, 2006)
La diseminación de la información es una de las razones de porqué el conocimiento ha adelantado tanto desde la segunda mitad del siglo XX. En este siglo se multiplicará de tal forma que es imposible sospechar los niveles ...
