Hyperspectral Coastal Image Analysis Toolbox (HyCIAT) enhancement: Subsurface linear unmixing and object detection by means of regularization
(2017)
This work presents an enhancement to the Hyperspectral Coastal Image Analysis Toolbox (HyCIAT). HyCIAT is a graphic interface developed in MATLAB, for the estimation of water optical properties, bathymetry and bottom ...
Semi-supervised document classification using ontologies
(2011)
Many modern applications of automatic document classification require learning accurately with little training data. Addressing the need to reduce the manual labeling process, the semi-supervised classification technique ...
Design of a compressed sensing system for hyper spectral imaging
(2014)
The advent of single pixel imaging brings the promise of lower sensor costs and higher efficiency by implementing spatial compression at the same time the image is sensed. This is achieved with the use compressed sensing ...
Algoritmos de Estimación e Interpolación de Parámetros Geofísicos
(2004)
Este trabajo de tesis está encaminado a encontrar modelos para estimar e interpolar espacialmente algunos parámetros de la superficie de suelo, específicamente para la región de Puerto Rico, tales como temperatura, índice ...
On-chip power management unit for multi-band ambient RF energy harvesting oriented to IOT and WSN applications
(2021-05-10)
Several attempts have been made to reduce or eliminate the use of batteries in remote electronic applications such as IoT and WSN nodes. However, most designs are constrained to operate under very specific conditions, and ...
Agrowebpr - a web-based application for connecting Puerto Rico’s food supply chain
(2014)
This work presents distributed three-tier architecture based web application, named AgroWebPR, providing ubiquitous and secured access to the distribution and purchasing of agricultural products. In this era of technology ...
Cost effectiveness of a residential cooling system through a solar thermal collectors design
(2010)
In this project I study the energy savings effect, environmental pollutants of carbon dioxide (CO2) and system cost feasibility in a residential air conditioning system with the implementation of a solar absorbing cooling ...
Estimation of vessel wall compliance using acoustic reflectometry
(2006)
This thesis focuses on the estimation of rubber tube wall compliance using a pulse echo-acoustic reflectometry technique. Five rubber latex tubes of different thicknesses were studied using a transient acoustic pulse, ...
A design and implementation of an electronic physician orders entry system
(2005)
The main objective of this project is to design and implement a physician order entry application for an electronic patient record system applying usability concepts. This application can improve the quality of care for ...
A novel fft pruning algorithm: improving efficiency for a nc-ofdm cognitive radio
(2012)
Cognitive Radio (CR) is a promising candidate to deploy future wireless networks because CR can enable an efficient use of the resources involved in wireless communications networks, specifically the Electromagnetic (EM) ...
