A quadratic model for budget planning related to the diet problem
(2014)This research deals with a variation of the notorious diet problem, which seeks to minimize the budget needed for an individual’s diet, subject to nutritional constraints, among others. Here, we address the problem from a ... -
Qualitative identification of fecal coliform bacterial sources
(2006)The main objective of this work is to provide a procedure to identify fecal coliform bacterial contamination sources within specific regions employing Geographical Information Systems (GIS) technology. The work presented ... -
Quantification of the transcriptional activity of genes associated with cyanogenesis in Cassava (Manihot esculenta Crantz)
(2008)Cassava has cyanogenic glycosides in its roots and leaves. These compounds function in plants as protective agents against herbivores as well as the translocable form of reduced nitrogen. The genes involved in the cyanogenic ... -
Queen triggerfish Balistes vetula reproductive biology in US Caribbean waters
(2018-05)Effective fisheries management requires a detailed understanding of the life history strategies of managed species. Queen Triggerfish Balistes vetula supports productive fisheries in the western Atlantic, including in ... -
Quinoa and amaranth: multi-purpose agro-industrial crops
(2019-03-19)Studies were conducted in 2018 with two multi-purpose agro-industrial crops [quinoa (Chenopodium quinoa Willd.) and amaranth (Amaranthus sp.)] to characterize its chemical composition. Limited information is available on ... -
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 ... -

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 ... -
