In this study, a multi-fidelity shape optimization framework is proposed for the pedestrian-level wind environment (PLWE). framework, low-fidelity computational fluid dynamics (CFD) models based on steady Reynolds-averaged Navier–Stokes equations (RANS) and high-fidelity CFD large-eddy simulation (LES) are efficiently integrated into process to improve reliability while maintaining its speed in...

This study presents a global real-time control (RTC) approach for sustainable and adaptive management of stormwater. A network inter-connected devices are assumed to dynamically generate the required set-points system actuators at remote center where optimization algorithms calculate operational decision-making target values. These values activate local controllers manipulate spatially distribu...

The Gaussian mixture model (GMM) is commonly used to the heavy tail of ground-based augmentation system (GBAS) range error distribution. In practice, over-bounding based on a GMM over-bound ranging errors, but GBAS protection levels (PLs) tend be overestimated. Based idea solution separation and overcoming shortcoming its direct reference GBAS, this paper analyses constraint conditions objectiv...

we consider the effect of changes of scale of measurement on the conclusion that a particular solution to a scheduling problem is optimal. The analysis in this paper was motivated by the problem of finding the optimal transportation schedule when there are penalties for both late and early arrivals, and when different items that need to be transported receive different priorities. We note that ...
