Seismic analysis of the embedded control tower at Success Dam
(2006)This thesis presents the analyses carried out to compute the Dynamic Soil-Structure Interaction (DSSI) effects of the embedded control tower at Success Dam, California. The particular case of the Success Dam in Sacramento, ... -
Seismic background noise of puerto rico
(2008)In this thesis, the seismic background noise in Puerto Rico was characterized using data from eleven broadband seismic stations for a period of three years from 2005 to 2007. Then the calibration files and data conversion ... -
Seismic performance and fragility curves for reinforced concrete frame and shear wall residential buildings in Puerto Rico
(2007)Puerto Rico is situated in an earthquake prone region. Most of residential buildings in Puerto Rico are reinforced concrete structures. Because of the imminent risk of being affected by a strong earthquake, it is important ... -
Seismic rehabilitation of typical schools in Puerto Rico
(2019-12-10)Puerto Rico is located in an earthquake-prone region. Observations from recent studies of seismic activity in Puerto Rico have proven the expectation of a major earthquake that may occur at any given time. School buildings ... -
Seismic response of inelastic concrete structures using the equivalent linear method
(2016)The equivalent linear method is widely used in Geotechnical Earthquake Engineering to calculate the accelerations at the surface of soil deposits subject to earthquakes of moderate intensity. The method approximately takes ... -
Seismic response of RC frame buildings with non reinforced exterior beam column joints
(2011)Recent earthquakes have demonstrated the risk that reinforced concrete structures constructed before 1970 represent for society since these structures were designed with design codes in which the seismic provisions were ... -
Seismic soil pressures on rigid walls subjected to pulse-like earthquake ground motions
(2021-05-11)Pulse-like earthquakes are believed to impose larger structural demands on structures due to the sudden release of seismic energy. This can cause concern in areas that are near fault due to the possibility of structures ... -
Selección de líneas de frijol (Phaseolus vulgaris L.) que combinan resistencia al gorgojo común (Acanthoscelides obtectus Say) con resistencia a los virus BGYMV, BCMV y BCMNV
(2016)Durante el almacenamiento, la semilla de frijol puede sufrir considerables pérdidas económicas causadas por los gorgojos tales como el gorgojo común del frijol (Acanthoscelides obtectus) Say. Las pérdidas causadas por este ... -
Selective hydrodeoxygenation of biomass-derived oxygenates over heterogeneous Mo-based catalysts
(2021-07)The development of catalytic pathways to produce commodity chemicals from lignocellulosic biomass is promising for substituting non-renewable fossil feedstock use. This dissertation studied the catalytic performance of ... -
Selective nanoporous sorbents for gas based separations: Ion exchanged silicoaluminophosphates and titanosilicates
(2009-05)Two specific sorbents were targeted in this research work: silicoaluminosphosphates (SAPOs) and titanium silicates. For the former, Na+ -SAPO-34 sorbents were ionexchanged with several cations (Ag+, Mg2+, Ca2+, Sr2+, Ti3+, ... -
Self-assembly of Janus Magnetic colloids with radially shifted dipole
(2019-07-11)The self-assembly Janus Magnetic colloids with radially shifted dipole are stud- ied using Brownian dynamics simulations, by is using a quasi-two-dimensional sys- tem. The properties and behavior of the process of ... -
Semantic metadata extraction from open domain texts in natural language
(2013)The information existing on the Web is growing immensely, and has posed a great challenge to users when searching for information and documents about a specific topic. Current search engines, though quite effective, fall ... -
Semántica narrativa y coherencia interna en los relatos de Senel Paz
(2001-05)El apogeo cultural y literario que florece durante la década de los años ochenta en Cuba no debe verse como un acontecimiento aislado, sino como el producto culminado de todo un trabajo literario que propulsa durante décadas ... -
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 ... -
Sensitivity analysis in the minimization of energy cost by combining the PREPA supply with a photovoltaic system
(2011)The manufacturing companies, the major consumers of energy, are constantly seeking alternatives to reduce energy consumption in their operations. Among the alternatives available to address this situation are industrial ... -
Separation, identification, and quantification of explosives using thin layer chromatography coupled to mid-infrared laser spectroscopy
(2019-05-10)The need for rapid instrumentation and methods for detection and identification of chemical and biological threat agents in national defense and homeland security settings has become an ever more important issue in modern ... -
Separational purification of nitrate from inedible biomass leachate by electrodialysis: fouling effect
(2004)The removal of nitrate and potassium from wheat leachate solution was studied using an electrolytic cell in batch recirculation mode for use in advance life support systems (ALSS). The ALSS or CELSS (Controlled Ecological ... -
Sequence diversity and expression of novel bacterial nitrous oxide reductase (Nosz) genes in tropical environments
(2008)Nitrous oxide (N2O) is produced in different microbial processes including denitrification, nitrification and dissimilatory nitrate reduction to ammonia (DNRA) (Kelso et al. 1999). It has been suggested that nitrification ... -
Sequence stratigraphic analysis of the Cotui Limestone, Upper Cretaceous of southwestern Puerto Rico
(2007)Different microfacies techniques were employed to study the sequences of deposition of the Cotui Limestone in southwestern Puerto Rico. These included the correlation between two sections, Cerro Buena Vista section in the ... -
Sequence stratigraphy of upper paleogene to neogene sedimentary rocks exposed from Guánica bay to Guayanilla Puerto Rico
