In this paper, finite‐time synchronization for a class of complex‐valued neural networks with time delays and discontinuous activations is concerned under the framework of Filippov solutions. Both state feedback and adaptive controllers are designed to overcome the difficulties in dealing with the time delay and the uncertainties of Filippov solutions. Based on the concept of Filippov solutions, differential...
In this paper, global synchronization in arrays of coupled networks with two time-varying delay coupling is investigated. Based on Lyapunov functional, we derive two synchronization conditions of these new complex network models by using linear matrix inequality(LMI). Due to two time vary delay, it can seen clearly from our results that the synchronization states change. Finally, a numerical example...
An endoscopic time-of-flight PET detector combined with an ultrasound probe will be designed and built to develop new biomarkers for pancreas and prostate tumors. The detector will consist of a PET head mounted on an ultrasound endoscope and an external PET detector plate with small crystals individually read out via silicon photomultipliers (SiPM). A 200 ps coincidence time resolution for background...
After introduced the C-C method of embedding window in state space reconstruction, this paper mainly calculates and analysis different time series samples of the Lorenz systems and Rossler systems with the method. The conclusion tells us the choice of reconstruction parameters with the C-C method is uncertain. So the embedding window theory is doubtful, and the independent choice of the state space...
