Model for electrodes' filaments of hot cathode fluorescent lamps, during preheating with constant rms current
(Institute of Electrical and Electronics Engineers (IEEE), 2007-05-01)
This paper presents a new model for the representation of electrodes' filaments of hot-cathode fluorescent lamps, during preheating processes based on the injection of currents with constant root mean square (rms) values. ...

Stability Analysis of Single-Phase Low-Voltage AC Microgrids With Constant Power Terminals
(Institute of Electrical and Electronics Engineers, 2019-07)
This express brief presents the stability analysis of single-phase microgrids (SP-MG) operating under master-slave connection with constant power terminals. The SP-MG is composed of linear elements, nonlinear loads and ...
Optimal Location of DGs in DC Power Grids Using a MINLP Model Implemented in GAMS
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper addresses the problem of optimal location and sizing of distributed generators (DGs) in direct-current (dc) power grids by using a mixed-integer nonlinear programming (MINLP) formulation. The reduction of the ...
Limits in late time conversion of cold dark matter into dark radiation
(Iop Publishing LtdBristolInglaterra, 2013)
Exercise tolerance can be enhanced through a change in work rate within the severe intensity domain: work above critical power is not constant
(Public Library Science, 2015)
The characterization of the hyperbolic power-time (P-tlim) relationship using a two-parameter model implies that exercise tolerance above the asymptote (Critical Power; CP), i.e. within the severe intensity domain, is ...
