Design of an Environmental Monitoring Program for a New Biotechnology Facility
(Polytechnic University of Puerto Rico, 2010)
A new biotechnology facility in Puerto Rico is in need of an Environmental Program to ensure the stability of room conditions for the manufacturing of their products. This environmental baseline study provided documented ...
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 ...
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 ...

Aprendizaje mediante la colaboración grupal (Cooperative Learning)
(Universidad Politécnica de Puerto Rico, 1998-12)
This work illustrates the needs of exposing the
students to learning experiences that develop and enhance their capabilities for analytical critical thinking in the solution of problems. The work in small groups with ...
Aplicación de sistemas de información geográfica en el análisis de la isla de calor urbana
(Universidad Politécnica de Puerto Rico, 1998-12)
An urban heat island has been described as the
difference in temperature between the city and its peripheral rural area. It is caused mainly by the growth of the city not taking into consideration the conditions previous ...
El impacto del paradigma constructivista en la enseñanza de matemáticas
(Universidad Politécnica de Puerto Rico, 1999-12)
The constructivist paradigm offers important
implications to educators about the teaching and
learning of mathematics. The curricular reforms in the mathematics classroom, in its majority, emerge from constructivist ...
Tools for Predicting Uncertainty and confidence Intervals in Radiometric Data Products
(Universidad Politécnica de Puerto Rico, 1999-12)
Spaced-based observations of atmospheric
energetics, such as those provided by NASA’s
Clouds and the Earth’s Radiant Energy System
(CERES), produce data products intended to be
shared with the larger scientific community ...
Simulation of the Antenna Pattern of Arbitrarily Oriented Very Large Phase/Time-Delay Scanned Antenna Arrays with Systematic and Random Errors
(Universidad Politécnica de Puerto Rico, 1999-12)
A computer simulation to determine the field
pattern of arbitrarily oriented, very large phase/time delay scanned antennas was developed. The simulation takes into account errors present in antenna arrays. These are ...
