[00415] Finite time horizon mixed control of vibrational systems

  • Session Date & Time : 5D (Aug.25, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : We consider a vibrational system control problem over a finite time horizon. The performance measure of the system is taken to be $p$-mixed $H_2$ norm which generalizes the standard $H_2$ norm. Our novel procedure efficiently takes into account the structure of the vibrational system. An objective function is represented in terms of integrals which are solved using adaptive quadrature rules. We illustrate our approach by numerical examples concerning an $n$-mass oscillator with one damper.

[01164] Infection spreading in tissue as a delayed reaction diffusion wave

  • Session Date & Time : 5D (Aug.25, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : In this work, we have discussed the stationary solution of a delayed reaction diffusion system for the concentrations of uninfected cells, infected cells, and virus cells. We have also discussed the existence of waves for the corresponding monotone system and found the minimal wave speed of the system. We have observed that when the death rates of uninfected and infected cells were the same, the virus propagation gradually decreases, but when the death rates are different, the wave propagation initially increases and then decreases. It is also observed that as the time delay increases the initial oscillations also increases. Next, we convert the system into a single diffusion equation using a quasi-stationary approximation, study the existence of the wave, and find the analytical expression for the minimal wave speed. We have also performed comprehensive simulations to compare and validate the results for both cases.

[01888] UAV Tracking and Targeting using YOLO with Enhanced Prior

  • Session Date & Time : 5D (Aug.25, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : Unmanned Aerial Vehicles defense becomes a hot topic due to the ongoing Ukraine-Russia War and China’s constant threats to Taiwan. Drones tracking and countermeasures inevitably play a crucial role in future warfare. Here, we propose a feature-enhanced Yolo network to improve the accuracy of detection and tracking for small moving objects. Multi-cores, multi-threads and field programming logic array combined with Kalman filtering are used to speed up our algorithm on edge devices such as cellphones.

[02288] An optimal design problem for materiales and shapes

  • Session Date & Time : 5D (Aug.25, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : A very important problem for industry consists of designing certain materials or objects which optimize some given properties. In this talk we present a recent advance in optimal material design problems in the sense that we introduce a double optimization factor, (controls), corresponding to the design of the material, (the \, microstructure,) and the domain, (the \, shape), of the object. We present some theoretical results through the homogenization theory and some numerical examples.

[00485] Adaptive event-trigger based disturbance rejection technique for nonlinear systems

  • Session Date & Time : 5D (Aug.25, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : In this work, the stabilization and disturbance rejection problem for a nonlinear system is discussed. In order to reduce the communication burden, adaptive event-triggered based control is proposed. Further, an improved equivalent-input disturbance estimate technique is incorporated to suppress the effects of external disturbances. A set of essential conditions are developed by applying Lyapunov stability theory to ensure the system is stable. Numerical examples with engineering significance are demonstrated to emphasize the effectiveness.
