Optimization of a SDOF Cantilever Beam Piezoelectric Energy Harvester with a Lump Mass at the End Tip
(Polytechnic University of Puerto Rico, 2016)
With the development of low power
electronics and energy harvesting technology, selfpowered systems have become a research hotspot
over the last decade. The main advantage of selfpowered systems is that they require ...
3D Vibration Isolation Systems Modeling for Air Handling Units
(Polytechnic University of Puerto Rico, 2014)
Spring isolators systems are commonly
used in a variety of ways in today’s construction
industry. They are an essential part of the design of
many mechanical systems that are in need of

Surface Response Modeling for Rotor-Dynamics Systems
(Polytechnic University of Puerto Rico, 2014)
This paper presents the way to
generate an equation that does not exist, to analyze
different rotor-dynamics system. With the analysis
and design software, the results desired were
obtained in order to be able to create ...
Stirling Engine Mechanism Analysis as a Function of Internal Pressure Variation
(Polytechnic University of Puerto Rico, 2014)
The Stirling heat engine was conceived
in the in the early 1800's as an alternative to the
steam engine. It is a regenerative close-cycle
engine which utilizes the expansion and contraction
of a working fluid at different ...
Parallel Plates Internal Heat Transfer Analysis for Electronic Cooling
(Polytechnic University of Puerto Rico, 2013)
Two-dimensional heat transfer analysis
using the Integral Equation Method between a
series of parallel plates with uniform surface
heating to determine the Temperature Distribution
as a Thermal Model for a Supercomputer ...
Development of an Open Source Tool for the Preliminary Structural Design of a Small Wind Turbine Based on National and International Standards
(Polytechnic University of Puerto Rico, 2013)
Wind energy have proven to be a viable
option in the production of electricity. The benefits
from wind energy sources include reductions in
greenhouse gas emissions, water conservation and
the diversification of the ...
