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

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 ...
Semisolid Metal Processing
(Universidad Politécnica de Puerto Rico, 1999-12)
Processing of metal alloys in their mushy state
represent a new trend in metal processing. The process produces components with low porosity,
high crack resistance, fine microstructure, and
better mechanical properties ...
