Abstract: Accurate traffic state estimation is essential for the successful application of intelligent transportation systems (ITS). In the past, traffic state estimation methods based on the macro traffic flow model and data ...

Abstract: The objective of this paper is to minimize fuel consumption needed for geostationary Earth orbit station keeping by Xenon Ion Propulsion System (XIPS) thrusters in failure mode under eclipse constraints. Two diagonal XIPS ...

Abstract: The heteroscedasticity refers to a collection of random variables with a subpopulation that have different dispersions from others. The variable dispersion could be quantified by measures of statistical dispersion such as ...
