A novel swarm intelligence optimization approach: sparrow search algorithm

open access: yesSystems Science & Control Engineering, 2020
In this paper, a novel swarm optimization approach, namely sparrow search algorithm (SSA), is proposed inspired by the group wisdom, foraging and anti-predation behaviours of sparrows.

Thinking fast and slow: Optimization decomposition across timescales [PDF]

open access: yesIEEE Conference on Decision and Control, 2017
Many real-world control systems, such as the smart grid and human sensorimotor control systems, have decentralized components that react quickly using local information and centralized components that react slowly using a more global view.

Analysis of Wellhead Uplift in Offshore Thermal Recovery by Using Finite Element Numerical Simulation

open access: yesJournal of Engineering, 2018
Pilot test of complex thermal fluid recovery technology was conducted in NB35-2 heavy oil field. Wellhead uplift was detected among some oil wells, and development of offshore thermal recovery technology could be restricted by the serious safety problems

Constrained ear decompositions in graphs and digraphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
Ear decompositions of graphs are a standard concept related to several major problems in graph theory like the Traveling Salesman Problem. For example, the Hamiltonian Cycle Problem, which is notoriously N P-complete, is equivalent to deciding whether a ...

Rapid and reliable re-design of miniaturized microwave passives by means of concurrent parameter scaling and intermittent local tuning

open access: yesScientific Reports, 2023
Re-design of microwave passive components for the assumed operating frequencies or substrate parameters is an important yet a tedious process. It requires simultaneous tuning of relevant circuit variables, often over broad ranges thereof, to ensure ...
