Source localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.Existing analysis Appetite Control of the Cram $acute{ ext{e}}$ r-Rao lower bounds (CRLB) shows that a hybr
One-pot three-component tandem annulation of 4-hydroxycoumarine with aldehyde and aromatic amines using graphene oxide as an efficient catalyst
Abstract A convenient and efficient solvent-free, facile, one-pot three-component graphene oxide catalysed approach has been described for the synthesis of chromeno-[4,3-b]quinolin-6-one derivatives from 4-hydroxycoumarin with aldehydes Hair Care Kits and aromatic amines.Graphene oxide (GO) has proved to be a new class of heterogeneous carbocatalys
Method for Designing Robust and Energy Efficient Railway Schedules
The robustness of the timetable is a sensitive issue in the daily realization of railway operations.As shown in the paper, robustness is a function of time reserves that helps to prevent unscheduled stops resulting from traffic disruptions and causing a higher energy consumption.The correct handling of time reserves while scheduling is a multidimen
