Bilinear Control for Three-Phase Microgrids: A Proportional-Integral Passivity-Based Design
(Cartagena de IndiasCampus Tecnológico, 2020-07-30)A bilinear PI control based on passivity theory for the adequate integration of distributed energy resources (DERs) in ac microgrids is presented in this paper. DERs are integrated into the grid by voltage source converters ... -
Biocontrol of Phytophthora root and stem rot disease in papaya (Carica papaya) plants by Photorhabdus, the symbiont bacterium of Heterorhabditis amazonensis
(Springer Netherlands, 2019)The effect of two strains of Photorhabdus spp. from Heterorhabditis amazonensis and their metabolites was tested against Phytophthora in laboratory conditions and in planta using papaya plants. The in vitro experiments ... -
Biomechanical Analysis of Common Postures during Mobile Phone Use
(Cartagena de Indias, 2020-12-24)The use of mobile phones for long periods of time has been associated with musculoskeletal and vision symptoms. This work uses simplified biomechanical models of the head, neck, back, and forearms to estimate the forces ... -
Black hole optimizer for the optimal power injection in distribution networks using DG
(Cartagena de Indias, 2021)The optimal sizing of Distributed Generators (DG) in electric power distribution networks is carried out through a metaheuristic optimization strategy. To size DG it is proposed an optimal power flow model is formulated ... -
Black hole-wormhole transition in (2+1)-dimensional Einstein-anti-de Sitter gravity coupled to nonlinear electrodynamics BLACK HOLE-WORMHOLE TRANSITION in (2+1)- ⋯ PEDRO CAÑATE and NORA BRETON
(American Physical Society, 2018)In this paper we present two results in (2+1) gravity coupled to nonlinear electrodynamics. First we determine the general form of the electromagnetic field tensor in (2+1) gravity coupled to nonlinear electrodynamics in ... -
Black-Hole Optimization Applied to the Parametric Estimation in Distribution Transformers Considering Voltage and Current Measures
(Cartagena de Indias, 2021-10-09)The problem of parametric estimation in single-phase transformers is addressed in this research from the point of view of metaheuristic optimization. The parameters of interest are the series resistance and reactance as ... -
Blind restoration of retinal images degraded by space-variant blur with adaptive blur estimation
(2013)Retinal images are often degraded with a blur that varies across the gield view. Because traditional deblurring algorithms assume the blur to be space-invariant they typically fail in the presence of space-variant blur. ... -
Bots and gender profiling on twitter using sociolinguistic features notebook for PAN at CLEF 2019
(CEUR-WS, 2019)Unfortunately, in social networks, software bots or just bots are becoming more and more common because malicious people have seen their usefulness to spread false messages, spread rumors and even manipulate public opinion. ... -
Boundary element analysis of laminated composite shear deformable shallow shells
(Elsevier Ltd, 2018)In this work, a Boundary Element Method formulation for stress analysis of symmetrically laminated composite thick shallow shells is presented. The proposed formulation was obtained by coupling the boundary element formulation ... -
Boundary element analysis of shear deformable shallow shells under harmonic excitation
(Tech Science Press, 2014)In this work, the harmonic analysis of shallow shells using the Boundary Element Method, is presented. The proposed boundary element formulation is based on a direct time-domain integration using the elastostatic fundamental ... -
Bracing alternatives in tapered frames under wind loads
(2009)The level of risk caused by forces of the nature could be reduced with an appropriate intervention of vulnerability, since such threats cannot be reduced. One of the alternatives to reduce the structural vulnerability of ... -
Bridged composite right/left handed unit cell with all-pass and triple band response
(2012)A modified design of the composite right/left handed (CRLH) unit cell showing all-pass and triple band response is proposed. By using an additional inductance which cross-couples the input and output ports of the conventional ... -
C 3 matching for asymptotically flat spacetimes
(Institute of Physics Publishing, 2019)We propose a criterion for finding the minimum distance at which an interior solution of Einstein's equations can be matched with an exterior asymptotically flat solution. The location of the matching hypersurface is thus ... -
