Published in 2017 at "Journal of Advances in Modeling Earth Systems"

DOI: 10.1002/2016ms000796

Abstract: Previous studies using idealized numerical simulations to understand the tropical cyclone (TC) response to time-varying wind shear have applied instantaneous changes in the TC environment. This was typically accomplished by pausing the simulation, constructing a… read more here.

Published in 2017 at "Asian Journal of Control"

DOI: 10.1002/asjc.1409

Abstract: The stability analysis problem is considered for linear discrete-time systems with time-varying delays. A novel summation inequality is proposed, which takes the double summation information of the system state into consideration. The inequality relaxes the… read more here.

Published in 2018 at "Asian Journal of Control"

DOI: 10.1002/asjc.1539

Abstract: This paper investigates the synchronization problem of a class of complex dynamical networks via an adaptive control method. It differs from existing works in considering intrinsic delay and multiple different time-varying coupling delays, and uncertain… read more here.

Published in 2019 at "Asian Journal of Control"

DOI: 10.1002/asjc.2091

Abstract: This paper deals with the simultaneous stabilization problem for a family of discrete time‐varying linear systems in the framework of nest algebra. Under the transmission condition, a necessary and sufficient condition for simultaneous "stabilizability" is… read more here.

Published in 2020 at "Asian Journal of Control"

DOI: 10.1002/asjc.2305

Abstract: This paper investigates adaptive tracking control in task space for robot manipulators with uncertain system dynamics, input saturation, and time‐varying output constraints simultaneously. An auxiliary system is constructed to compensate the effect of the input… read more here.

Published in 2021 at "Asian Journal of Control"

DOI: 10.1002/asjc.2630

Abstract: This work presents a consensus strategy for multiagent networked systems with time‐varying delays. A new control technique is first developed, named observer‐based distributed periodic event‐triggered control. Aiming at leader‐following consensus strategy, the state update of… read more here.

Published in 2020 at "Bioelectromagnetics"

DOI: 10.1002/bem.22292

Abstract: The ability of extremely low, time-varying electromagnetic field (EMF) to improve germination efficacy was studied in Foxtail millet (Setaria italica) seeds using response surface methodology. An optimal factorial central composite design was chosen to optimize… read more here.

Published in 2021 at "Brain and Behavior"

DOI: 10.1002/brb3.2334

Abstract: The extensive development of graph‐theoretic analysis for functional connectivity has revealed the multifaceted characteristics of brain networks. Network centralities identify the principal functional regions, individual differences, and hub structure in brain networks. Neuroimaging studies using… read more here.

Published in 2019 at "Environmetrics"

DOI: 10.1002/env.2596

Abstract: Maximum analysis consists of modeling the maximums of a data set by considering a specific distribution. Extreme value theory (EVT) shows that, for a sufficiently large block size, the maxima distribution is approximated by the… read more here.

Published in 2021 at "Earth Surface Processes and Landforms"

DOI: 10.1002/esp.5107

Abstract: Sandy beaches typically have one or more shore‐parallel bars with superimposed smaller‐scale three‐dimensional (3D) bars. Knowledge of their morphodynamic behaviour under more realistic wave conditions is limited. This study investigates the response of beaches with… read more here.
