Voltage Regulation in a Power Inverter Using a Quasi-Sliding Control Technique
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-07-01)
This paper shows the behavior of a three-phase power converter with resistive load using a quasi-sliding and a chaos control techniques for output voltage regulation. Controller is designed using Zero Average Dynamic (ZAD) ...
Turbulence in the middle atmosphere: A review
(1980)
The stratosphere is characterized for being highly statically stable. lt takes considerable energy to interchange parcels of air from different altitudes; thus, turbulence is normally inhibited, Wind shears of the order ...
A singular vorticity wave packet within a rapidly rotating vortex: spiralling versus oscillating motions
(2019)
This paper considers a free vorticity wave packet propagating within a rapidly rotating vortex in the quasi-steady regime, a long time after the wave packet strongly and unsteadily interacted with the vortex. We study a ...
A singular vortex Rossby wave packet within a rapidly rotating vortex
(2017)
This paper describes the quasi-steady regime attained by a rapidly rotating vortex after a wave packet has interacted with it. We consider singular, nonlinear, helical, and shear asymmetric modes within a linearly stable, ...
The qT spectrum of the Higgs boson at the LHC in QCD perturbation theory
(Elsevier Science, 2003-07)
We consider the transverse-momentum (qT) distribution of Higgs bosons produced at hadron colliders. We use a formalism that uniformly treats both the small-qT and large-qT regions in QCD perturbation theory. At small qT ...
Sistema de recirculação e rotina de manejo para larvicultura de camarões de água doce Macrobrachium rosenbergii em pequena escala
(Inst Pesca, 2009-01-01)
A recirculating system and a matching management schedule for small-scale freshwater prawn larviculture were described. The system comprised a 140 L larval culture tank in line with a 43 L biofilter filled with 24 L of ...
Variation of the gain through coupling networks of Narrow Band Amplifiers
(2006)
Variable gain microwave amplifiers are widely used today. A new method for the variation of gain is presented for narrow band microwave amplifiers. The technique is based on the variation of inductance and capacitance in ...

Agrupación de genes en ciencia intensiva: Comparación y análisis de tendencia mediante el índice de estabilidad biológica.
(Escuela Superior Politécnica de Chimborazo, 2019-12-23)
This research evaluates the performance of the best known clustering algorithms using the biological stability index (BSI). A comparison was made between the clustering algorithms, to determine which is the optimum according ...
BtoxDB: a comprehensive database of protein structural data on toxin-antitoxin systems
(Elsevier B.V., 2015-03-01)
Purpose: Toxin-antitoxin (TA) systems are diverse and abundant genetic modules in prokaryotic cells that are typically formed by two genes encoding a stable toxin and a labile antitoxin. Because TA systems are able to ...
