[00809] Mathematical Aspects of Metaheuristics in Medical Imaging and Pattern Recognition

Session Time & Room : 2D (Aug.22, 15:30-17:10) @A201
Type : Contributed Talk
Abstract : Medical imaging and pattern recognition have very important applications in the health and other industrial sectors. In this talk, we will be focusing on the mathematical model that deals with high-order graph matching using a metaheuristic technique. This model has been tested real-life images including identifying white blood cells in human blood. The models work on the idea of artificial intelligence and have a high level of efficiency with good results. The role of AI is in terms of AI-based metaheuristics which are used as search and optimization techniques to address aforementioned problems.

[00078] A higher order numerical scheme to a nonlinear McKendrick-Von Foerster equation with singular mortality

Session Time & Room : 2D (Aug.22, 15:30-17:10) @A201
Type : Contributed Talk
Abstract : In this paper, higher-order numerical schemes to the McKendrick-Von Foerster equation are presented when the death rate has singularity at the maximum age. The third, fourth-order schemes that are proposed are based on the characteristics, which are non-intersecting lines in this case, and are multi-step methods with appropriate corrections at each step. In fact, the convergence analysis of the schemes is discussed in detail. Moreover, numerical experiments are provided to validate the orders of convergence of the proposed third-order and fourth-order schemes.

[00655] Finite-time fault-tolerant robust control design for parabolic partial differential equations

Session Time & Room : 2D (Aug.22, 15:30-17:10) @A201
Type : Contributed Talk
Abstract : In this paper, a finite-time fault-tolerant robust control design for parabolic partial differential equations in the presence of uncertainties, actuator faults and external disturbances is discussed. The main aim is to design a non-fragile fault-tolerant control to ensure the robust stabilization of the considered PDEs. By employing Lyapunov method, a novel set of conditions is obtained to ensure the required result. Finally, simulations are provided to demonstrate the effectiveness of the developed control design.

[01059] EVENT-TRIGGERED CONTROL FOR PARABOLIC PARTIAL DIFFERENTIAL EQUATIONS WITH CYBER-ATTACKS

Session Time & Room : 2D (Aug.22, 15:30-17:10) @A201
Type : Contributed Talk
Abstract : An event-triggered control for parabolic-type partial differential equations subject to disturbances and cyber-attacks is addressed in this talk. To attenuate the disturbances an H∞ performance is considered. By designing an appropriate Lyapunov-Krasovskii functional the stabilization conditions for the considered parabolic type partial differential equations are obtained in the form of linear matrix inequalities. Finally, a numerical example is provided to verify the efficiency of the derived theoretical results.

[01008] EID estimator-based Control Design for Singular Polynomial Fuzzy Systems

Session Time & Room : 2D (Aug.22, 15:30-17:10) @A201
Type : Contributed Talk
Abstract : This paper studied the disturbance rejection problem for singular polynomial fuzzy system based on equivalent-input-disturbance-estimator-based control approach. The proposed approach is used to compensate the influences of unknown lumped disturbance. To cope the robust stability problems, the augmented closed-loop system is constructed that includes dynamics of the system, observer, and low-pass filter. Lyapunov stability theory is used to develop stability conditions for the resulting system. Finally, numerical examples are provided to validate the theoretical result.

[01964] Competitions between stage-structured species in a patchy environment

Session Time & Room : 2E (Aug.22, 17:40-19:20) @A201
Type : Contributed Talk
Abstract : In this study, an ecological model with two life stages, immature and mature, and incorporating both intra- and inter-competitions between two species is explored to study invasion of species in a two-patch environment. It can be applied to exploring evolution of insects like Drosophila and beetles, which experience larva and adult (immature and mature life stages). The monotone dynamics in such a model provides us a property to explore its local and global dynamics. The model can also admit complex dynamics with multiple positive equilibria and limit point bifurcation when both species persist.

[01854] Dynamic Roughness in the Term Structure of Oil Markets Volatility

Session Time & Room : 2E (Aug.22, 17:40-19:20) @A201
Type : Contributed Talk
Abstract : This paper analyses the attributes and the significance of the roughness of oil market volatil- ity. We employ unspanned stochastic volatility models driven by rough Brownian motions that yield semi-analytic prices for futures options entailing efficient calibration applications. We calibrate option prices written on oil futures and provide empirical evidence of the dy- namic nature of the roughness in oil volatility. The calibrated option-implied Hurst param- eter varies over time, but rough stochastic volatility models provide a better fit to the term structure of implied oil volatility compared to classical stochastic volatility. Furthermore, including the Hurst parameter into the set of implied parameters benefits the stability of the calibrated parameters and improves pricing performance.

[00205] `Period doubling' induced by optimal control in a behavioral SIR epidemic model.

Session Time & Room : 2E (Aug.22, 17:40-19:20) @A201
Type : Contributed Talk
Abstract : We consider a behavioral SIR epidemic model to describe the action of the public health system aimed at enhancing the social distancing during an epidemic outbreak. An optimal control problem is proposed where the control acts in a specific way on the contact rate. We show that the optimal control of social distancing is able to generate a period doubling–like phenomenon. Namely, the ‘period’ of the prevalence is double the ‘period’ of the control, and an alternation of small and large peaks of disease prevalence can be observed.
