R-torsion on (2,n)-torus knots.
(2018-11-02)This thesis study the (2,n)-torus knots, uses the Khovanov Homology and Reidemeister Torsion. We show the study made to the Khovanov Homology Groups H^r, for r = -n, -n+1, -1; 0. These are isomorphics to either Z, Z_2 ... -
The r/evolution of the Victorian femme fatale
(2016)The focus of this thesis is to examine the construction of femme fatale representations of nineteenth century England, particularly in mid- Victorian to fin-de-siècle art and literature, thus tracing radical and significant ... -
Radiation tolerance and signal risetime of the cms pixel detector
(2013)The Compact Muon Solenoid (CMS) is one of the main experiments at the large hadron collider (LHC). This thesis presents the study of two important features of the CMS pixel detector. The first study shows the performance ... -
Rain gauge concept using s-band and w-band for estimation of moderate to heavy precipitation
(2004)In this research, two Doppler radars working at W-band (95GHz) and at S-band (2.8GHz) together with radiosonde observations (RaOb) were used to retrieve physical parameters such as rainfall rate and vertical air motion ... -
Rare earth ( Π = Ce, Er, Pr) substituted Bi (4-X) Π X Ti3O12 thin films: synthesis, structural and ferroelectric properties
(2005)In the present research, rare earths (Π= Ce, Er, Pr)-substituted bismuth titanate Bi(4-x) ΠxTi3O12 thin films were synthesized by a chemical solution deposition (Sol-Gel) technique. Films were deposited by spin coating on ... -
Re-creating the text: Jane Austen’s Pride and Prejudice and its film adaptations
(2009)Film adaptation is a relatively new and popular form of studying texts, which is very important to our society because of the effect that adaptation has on it. The differences between the “original” text and adaptation ... -
Re-engineering a diverse service system: Multi-criteria resource assignment
(2017)Balancing supply and demand in service organizations is a complex problem that should be approached using mathematical modeling. This work developed a resource assignment formulation that deals with the mismatch between ... -
Reading attitudes, habits and performance of third grade ESL students participating in a reading challenge program
(2009)The study examines the reading attitudes, habits, and performance of third graders in an urban elementary school in Mayagüez, Puerto Rico participating in a 20 Book Reading Challenge Program. Five methods were used: ... -
A real-time manufacturing information exchange application between programmable logic controllers over a fault tolerant network
(2004)An increase during the last fifteen years in seeking opportunities in data acquisition, reporting, and integrated control systems in automated factory floor environments has gained high priority for Enterprises Information ... -
A real-time manufacturing information exchange application between programmable logic controllers over a fault tolerant network
(2015)This thesis presents the development of a test method for diagnosing the presence of embedded systems failures caused by physical defects in the printed circuit board and electronic components. Specifically, the proposed ... -
A real-time manufacturing information exchange application between programmable logic controllers over a fault tolerant network
(2014)This thesis presents the development of a test method for diagnosing the presence of embedded systems failures caused by physical defects in the printed circuit board and electronic components. Specifically, the proposed ... -
Recommendations of bridge distribution factors for military vehicles on steel beam bridges
(2007)Analyses were carried out to develop live load distribution factors for the seven most common US Army military vehicles on ninety steel multi-beam bridges. The bridges were analyzed by the finite element method (FEM) to ... -
A reconfiguration algorithm for a dc zonal electric distribution system based on graph-theory methods
(2009)In many applications, self contained Electric Power Distribution Systems (EPDS) require high survivability under fault conditions. A fault produces an immediate change in the system topology resulting in potential loss of ... -
Reconstructing sea surface temperatures in the Caribbean during the early-mid Holocene from a reef exposure in Cañada Honda, Enriquillo Valley, Dominican Republic
(2015)Temperatures during the Holocene are driven by seasonal changes in insolation; however, a better understanding of insolation mechanisms and how it affects tropical climate is still necessary. This study presents annual ... -
Recovery of client query work in the nettraveler middleware system
(2006)This thesis presents NetTraveler, a Database Middleware System for Wide Area Networks that is designed to efficiently run queries over sites that are either mobile clients or enterprise servers. NetTraveler is designed to ... -
Recovery of compressively-sampled reflectance confocal microscopy images of human skin using advanced machine learning techniques
(2019-12-10)Compressive Sensing (CS) has demonstrated a great potential for the improvement of acquisition, manipulation, and storage operations on a variety of different applications with little to no discernible loss in terms of ... -
Red hind Epinephelus guttatus vocal repertoire characterization, temporal patterns and call detection with micro accelerometers
(2019-05-14)Passive acoustic monitoring has been used to study groupers that produce courtship associated sounds (CAS) when they aggregate to spawn. This technique has revealed patterns of sound production during red hind (Epinephelus ... -
Red light running and driver behavior at signalized intersections in western Puerto Rico
(2011)Red Light Running (RLR) is a potentially severe safety issue at signalized intersections. To determine the driver reaction at the end of the green period at signalized intersections, a RLR study was performed using 32 ... -
Redes neuronales artificiales y funciones de transferencia aplicados a la estimación de humedad de suelo y temperatura del aire
(2007)Statistical, mathematical and artificial neural networks techniques were used to estimate the behavior of the following variables: the air temperature (AT) and the soil moisture (SM). The AT plays an important role in ... -
Redesign of a signalized intersection using non-conventional left turn treatments to optimize level of service and delays: Western Plaza case study
(2016)Congestion and safety problems at intersections have been on the rise due to the increased traffic volumes throughout mainline corridors in Puerto Rico, as well as in the United States. As a result, new and innovative ...
