In this paper we use pupil diameter as an indicator for measuring cognitive load for six different tasks on common web maps. Two eye tracking data sets were collected for different basemaps (37 participants and 1,328 trials in total). We found significant differences in mean pupil diameter between tasks, indicating low cognitive load for free exploration, medium cognitive load for search, polyg...

In this paper, a novel method based on Hybrid Genetic Algorithm and Particle Swarm Optimization (HGAPSO) technique is proposed for solving Under Voltage Load Shedding (UVLS) problem. Load curtailment as ultimate control action is performed by under voltage load shedding scheme to guarantee power system voltage stability in contingency conditions. In addition, the proposed under voltage load she...

Transient stability plays key role for the loading of Extra High Voltage AC lines under their thermal limits. It is not possible to load these EHV lines near the thermal limits. But, with the proposed scheme in this paper, it is possible to load these lines very close to their thermal limits. Master current controller senses ac current and regulates the dc current orders for converters online s...

This paper describes a new methodology based on peak load consideration for reliability evaluation of a generation system. The methodology has been developed using Simpson’s (1/3) rule for loss of load probability (LOLP) evaluation. Load models are considered as straight line and stepped load duration curve for reliability evaluation. The LOLP evaluation is based on peak load consideration. The...

By using a water transmission line, current wave shaping was demonstrated for a fast capillary Z-pinch discharge recombination soft x-ray laser study. The pulsed power system consists of a water capacitor, a gap switch, a transmission line, and a capillary plasma load. A voltage wave initiated at the water capacitor propagates toward the capillary load through the transmission line. Control of ...

| Interconnect in VLSI circuits is best modeled as a lossy transmission line in high speed integrated circuits. Analytical expressions for the coupling noise between adjacent interconnect are presented to estimate the peak noise voltage on a quiet line based on the assumption that these interconnections are loosely coupled, where the e ect of the coupling noise on the waveform of an active line...

BACKGROUND To guide future need for cheap resistance tests for use in low income settings, we assessed cost-effectiveness of drug resistance testing as part of monitoring of people on first line ART - with switching from first to second line ART being conditional on NNRTI drug resistance mutations being identified. METHODS An individual level simulation model of HIV transmission, progression ...
