Una radio comunitaria para el fomento de la cultura y la educación : Caso Condado de Horry, Carolina del Sur
(2016-05-26)Este proyecto consistió en el diseño de una radio cultural comunitaria, que fue implementada en la comunidad hispana en el Condado de Horry en Carolina del Sur, entre agosto 2015 y marzo 2016. Dotar a esta comunidad de ... -
Understanding language ideologies in Puerto Rico: From colonialism to translanguaging
(2015)This thesis provides an historical analysis of the evolution of the monolingual paradigm in Puerto Rico. It traces the origins of the monolingual paradigm from the rise of the modern European nation-state, through US ... -
Understanding operator preferences towards manufacturing cell task assignments
(2013)Empirical research has shown that the majority of cellular manufacturing (CM) implementations do not consider in their design and operational phases socio-technical factors. However, in practice the performance and success ... -
Understanding the atmospheric turbulence structure parameter, Cn2, in the littoral regime
(2006)Understanding optical propagation through atmospheric turbulence is a highly important step for the efficient implementation of a free space laser communication system and for achieving diffraction limited imaging over ... -
Understanding the effect of spatial resolution on unmixing algorithms for hyperspectral imagery
(2010)This research work presents an experimental study on unmixing of hyperspectral images at different spatial resolutions. The study looks at how the assumptions made in the unmixing procedure affects the results of the ... -
Understory Plant Communities in the Surroundings of the Joyuda Lagoon, Puerto Rico
(2012)Studies focused on the distribution of understory species associated with mangrove forests are very scarce. This research provides a detailed description of the understory community and their environmental requirements at ... -
Unlocking the portals of the political culture : marginalized feminist voices of color and fictional women leaders
(2018-12-10)This dissertation first seek to analyze and evaluate various arguments that have been put forward by Contemporary Feminist thinkers on critical feminist cultural, gender, identity and race theory. These scholarly discussions ... -
Unmanning lessons : emasculation in novels by C.L.R. James, Garth St. Omer, and Orlando Patterson
(2021-01-29)Caribbean men have been affected by racist, classist, and sexist discourses and praxes that privilege “true” masculinity (i.e. heterosexual, usually Anglo-Saxon) at the expense of “lesser” masculinities (non-binary, African, ... -
Unraveling the microbiome of the snail Caracolus marginella using metagenomics
(2018)The increased of Antibiotic Resistance (AR) is currently one of the most important public health threats faced worldwide. Increasing rates on AR has been observed globally. The use and analysis of non-traditional techniques ... -
Unsupervised classification of text documents
(2007)The automatic extraction of knowledge from very large document collections is becoming an important issue in order to exploit the increasing available information stored in text form. A significant aspect of this extraction ... -
Unsupervised unmixing analysis based on multiscale representation
(2013)Unsupervised unmixing analysis aims to extract the basic materials, the so called endmembers, and their abundances from a hyperspectral image. Unmixing is usually performed by pixels-only techniques that do not take into ... -
Unsupervised unmixing of hyperspectral imagery using the constrained positive matrix factorization
(2007)In hyperspectral imaging, hundreds of images are taken at narrow and contiguous spectral bands providing us with high spectral resolution spectral signatures that can be used to discriminate between objects. In many ... -
Untangling the effects of biogeography and host plant associations: phylogenetic and phylogeographic studies in the Exophthalmus genus complex
(2011)Phylogenetic as well as phylogeographic methods were implemented to assess the diversification of Caribbean entimine weevils. (1) A phylogeny of 62 species of entimine weevils (Coleoptera: Curculionidae: Entiminae) in the ... -
Use of ambient vibration measurements to estimate site fundamental periods at Condado and Isla Verde, PR
(2016-12)The knowledge of the natural periods of soil deposits in urban areas can be very valuable for the safe design of structures to avoid resonance conditions. This thesis presents a study aimed to estimate site natural periods ... -
The use of backpropagating neural networks in coordination with logistic spline coefficients to obtain the change-point
(2006)This work presents an algorithm that uses backpropagating neural networks and their ability to find logistic regression coefficients as a useful tool that may outperform other conventional methods for finding the change-point ... -
Use of crosslinked hydrogels for the control of macromolecular crystallization
(2012)Crosslinked hydrogels in protein crystallization is an area of continuous growth. The counterdiffusion technique is a novel method for the crystallization of proteins, which entails the minimization of convection effects, ... -
Use of driving simulator for the operational and safety evaluation of signage and pavement markingss: a case study of P.R. Dynamic Toll LANE
(2018)This research study evaluates alternative overhead signs and in-lane pavement markings in the existing 10.4 km (6.5 mi) PR-22 Dynamic Toll Lane (DTL) facility in Puerto Rico. The DTL is a type of managed lane that combines ... -
Use of passive acoustic recordings to quantify abundance relationship from courtship associated sounds of the Nassau grouper (Epinephelus striatus) at spawning aggregation sites in Puerto Rico and the US Virgin Islands
(2015)The Nassau grouper, Epinephelus striatus, has been overfished to commercial extinction, such that many aggregations have diminished or disappeared throughout the Caribbean. Groupers produce sound, and the objective of this ... -
Use of polydimethyl siloxane microparticles for the sequestering of model pollutants in water
(2009)Polymer micro and nanoparticles are an emerging type of material with promising applications for remediation and degradation of environmental contaminants in water, due to their enhanced surface area and chemical reactivity. ...
