Abstract This paper focuses on the scheduling under uncertainty of satellite tracking from a heterogeneous network ground stations taking into account allocated resources. An optimisation-based approach is employed to efficiently select optimal schedule that minimises final estimation uncertainty. Specifically, formulated as variable-size problem, and Structured-Chromosome Genetic Algorithm dev...

This study has been inspired by the paper "An efficient 3D topology optimization code written in MATLAB” written by Liu and Tovar (2014) demonstrating that SIMP-based three-dimensional (3D) topology optimization of continuum structures can be implemented in 169 lines of MATLAB code. Based on the above paper, we show here that, by simple and easy-to-understand modificati...

In this paper we identify the common building blocks that enable some networks to provide better than best-eeort transfer guarantees to the traac they carry. We consider the role signaling plays in such a network and argue in favor of: pinned routes, with a highly eecient pinning process, to improve network stability and to ease the task of maintaining Quality of Service (QoS) guarantees in the...

The planning of urban bus-only lane networks is an important measure to improve bus service and bus priority. To determine the effective arrangement of bus-only lanes, a bi-level programming model for urban bus lane layout is developed in this study that considers accessibility and budget constraints. The goal of the upper-level model is to minimize the total travel time, and the lower-level mo...

In this paper a generalization of the indirect pseudo-spectral method, presented in [17], for numerical solution budget-constrained infinite horizon optimal control problems is presented. Consideration problem statement framework weighted functional spaces allows to arrive at good approximation initial value adjoint variable, which inevitable obtaining solutions. The method illustrated by apply...
