Voltage Collapse and ODE Approach to Power Flows: Analysis of a Feeder Line with Static Disorder in Consumption/Production
Voltage Collapse Consumption/Production Feeder Line Static Disorder
2011/9/15
We consider a model of a distribution feeder connecting multiple loads to the sub-station. Voltage is controlled directly at the head of the line (sub-station), however,voltage anywhere further down t...
Control spiral wave dynamics using feedback signals from line detectors
spiral wave dynamics feedback signals line detectors
2010/4/6
We numerically study trajectories of spiral-wave-cores in excitable systems modulated proportionally to the integral of the activity on the straight line, several or dozens of equi-spaced measuring po...
Non-Twist Field Line Mappings for Tokamaks with Reversed Magnetic Shear
Non-Twist Field Line Mappings Tokamaks Reversed Magnetic Shear
2010/10/27
The structure of magnetic field lines in a tokamak with reversed magnetic shear is investigated by means of analytically derived area-preserving non-twist Poincar´e maps. The basic configuration...
Microwave Signal Attenuation in Harmattan Weather Along Calabar-Akampkpa Line-of-Sight Link
Harmattan Radio signal Fog attenuation Statistics of fade Calabar
2010/4/13
Line-of-sight (LOS) attenuation at 6.44GHz was measured at Calabar (4° 58' N, 8° 17' E) for ten months (Aug '93-May '94) using the Nigerian Telecommunications radio signal. The measurement was made wi...
In this study, the strong lines were examined to determine the effect of velocity gradient due to mass loss on the line profiles in the atmosphere of Deneb. The lines are formed in the optical depth r...
