Off the grid x-band radar node development for weather applications
(2010)The Student Led Test Bed (STB) is part of the NSF Engineering Research Center CASA and is currently focused on developing low infrastructure radar networks to fill lower atmosphere gaps not covered by current technology. ... -
Oil accumulation via Chlorella species using carbon sources from waste
(2009-12)One of the global issues acquiring significant attention these days is related to energy supply and demand. The irreversible decrease of fossil fuels left to supply energy and the greenhouse gases increase in the atmosphere ... -
On applications of rough sets theory to knowledge discovery
(2007)Knowledge Discovery in Databases (KDD) is the nontrivial extraction of implicit, previously unknown and potentially useful information from data. Data preprocessing is a step of the KDD process that reduces the complexity ... -
On chip solar energy harvesting system using substrate diode pv cell and fractional open circuit age implementation
(2018)The technological community is highly focused in the area of solar energy harvesting. Specifically, these efforts can be observed in the design of more efficient power management systems which can extract the maximum ... -
On implementing time-frequency representations on hardware/software computational structures for sar applications
(2006)Synthetic Aperture Radar (SAR) applications require that imaging systems be able to gather and process appropriate environmental information to aid in the process of effective decision making. This is the one major reason ... -
On improving the performance of wood-zinc roof systems
(2006)From hurricane Hugo to hurricane Georges, the majority of storm related losses in Puerto Rico were attributed to wood-zinc houses and auxiliary structures. Efforts to improve the performance of such systems is therefore ... -
On some algorithms for reverse engineering certain finite dynamical systems
(2005)There are two general problems related to finite dynamical systems (FDS): the analysis and the synthesis (also known as the reverse engineering) problems. In the former, we are interested in uncovering the sequential ... -
On the formalism of quantum mechanics constructed with the dispersion relation of deformed special relativity
(2011)Over the last ten years there has been a significant effort to develop Deformed Special Relativity (DSR). This theory has two observer invariant scales: the speed of light,(c), and the Planck energy,(Ep). It is argued by ... -
On the number of τ(n)-factor
(2016)In 2006, Anderson and Frazier defined the theory of τ-factorization as a generalization of the theory of comaximal factorizations given by McAdam and Swan. The theory of τ-factorization was built on integral domains. The ... -
On the properties and construction of Boolean bent and near-bent functions, and their applications to error-correcting codes for NASA deep-space
(2022-05-16)In this investigation, we research the properties of highly nonlinear vectorial Boolean functions in m variables and their connections to good error-correcting codes. We focus on "bent" and "near-bent” ... -
On the security of smart grid communications: vulnerabilities and countermeasures
(2015)Smart grid is an advanced power grid which has been developed to improve the efficiency and reliability of the electricity network. However, because of the complexity of the smart grid, it introduces many security issues. ... -
On the selection of commercially available Sn-Ag-Cu Pb-free balls components over re-balling the components with Sn37Pb balls to comply with the restriction of hazardous substances directive in the aerospace industry
(2009)A modeling approach based on physics of failure is presented that quantifies the interactions between different thermal cycles applied to Ball Grid Arrays (BGA). The approach is formulated at the microscale, incorporating ... -
On the three-dimensional structure of Caribbean mesoscale eddies
(2005)The three-dimensional structure of three Caribbean mesoscale features: a cyclone, an anticyclone and an eddy pair, was studied using a combination of in situ and satellite data. The formation and development, hydrography ... -
On the use of embedded devices for heterogeneous cloud infrastructure
(2016)Regardless of the type of user, be it a computer professional or smart-phone user, working in a small bank or at a high tech IT company, everyone is (knowingly or not) using cloud-computing. In fact, the cloud-computing ... -
On time-frequency analysis for structural damage detection
(2008)An integrated study that explores the capability of Time-Frequency Analysis combined with another technique of signal analysis and system identification for damage detection purposes using only output signals is presented ... -
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 ... -
On-line opinions and the role of “value” in the tourism industry in the Caribbean: A fuzzy data envelopment analysis approach to model island competitiveness
(2010)Tourist arrivals to the Caribbean have grown on average 3.2% per year in the last decade; however the percentage of repeated customers is uneven across islands. A conceptual model to guide value investment for the Caribbean ... -
On-line performance parameter estimation of SR-30 turbojet engine
(2010-12)Accurate estimation of jet engines performance parameters is the key to develop reliable diagnostics systems. The development of a reliable and accurate nonlinear model of the SR-30 turbojet engine is proposed. To comply ... -
Ontogenetic migration and growth of french grunt (Teleostei: Haemulon flavolineatum) as determined by coded wire tags
(2005-12)The early life history of grunts was studied using mark-recapture techniques. Juvenile fish (Haemulon flavolineatum) were tagged with coded wires and the effects of tagging were investigated in controlled tank experiments. ...
