Elicitation of part-worth utilities of quantified gestalt principles for product aesthetics
(2016-06)
This research explores the use of quantified Gestalt principles: symmetry, parallelism, and continuity, as design variables to evaluate the aesthetics of two-dimensional and three-dimensional product representations. To ...
Generation and dynamic control of air microbubbles subjected to a complex 3D acoustic field
(2016)
The purpose of this research is to verify that the translational movement of a microbubble in a complex three-dimensional geometry subjected to a standing acoustic field, can be predicted with the acoustic pressure gradient ...
High temperature die attach by low temperature gold-tin solid-liquid interdiffusion
(2012)
There is a need for electromechanical devices capable of operating in high temperature environments (>200°C) for a wide variety of applications. Today’s widebandgap semiconductor based power electronics have demonstrated ...
An acoustic method for real time air bubble detection in simulated blood vessels
(2012)
Exposure to significant changes in ambient pressure commonly occurs in divers during surfacing. These changes induce the formation of nitrogen bubbles in tissues and the presence of these bubbles can cause symptoms of ...
Design and characterization of a passive wireless DNA sensor
(2014)
In order to predict and avoid disasters due to gene mutation, reliable DNA information
is necessary to be monitored in real time. Existing DNA sensing technologies offer
outstanding performance in terms of the resolution ...
Ocean circulation modeling of the San Juan bay
(2013)
The Regional Ocean Modeling System has been implemented in the San Juan bay estuary, Puerto Rico, to investigate quantitatively the ocean currents at a harbor scale with tidal, wind and river forcing and to develop a ...
Stability of silver colloid by process control of the synthesis using design of experiments
(2013)
Extensive resources have been utilized to develop SiC (silicon carbide) semiconductor devices, there has been relatively little effort into the development of adequate, environmentally benign electronic packaging materials ...
Design and manufacture of a linear fresnel reflector prototype for coffee drying applications in Puerto Rico
(2014)
The need and desire to use renewable, sustainable, and efficient energy have led to increased research
in this field as the long term consequences of not doing so will affect the environment. As an alternative
to drying ...
Probing the hydrodynamics of plunging gravity waves through Lagrangian observations of inertial particle dynamics
(2013-07)
Understanding wave breaking phenomena is a challenging problem that still lacks satisfactory understanding. The present study is concerned with the development of novel instrumentation adapted to obtain Lagrangian field ...
Brownian dynamics simulation of colloidal particles in a Gay-Berne suspension
(2013)
Complex colloidal fluids have become an emerging composite material useful for novel industrial and technological applications. The dispersion of colloids in anisotropic fluids with crystal-like structures, such as nematic ...
