Modeling Method for the Coupling Relations of Microgrid Cyber-Physical Systems Driven by Hybrid Spatiotemporal Events

Xiaoyong Bo, Xiaoyu Chen, Huashun Li, Yunchang Dong, Zhaoyang Qu, Lei Wang
2021 IEEE Access  
It is difficult for these models to accurately describe spatiotemporal deduction processes, such as microgrid CPS attack identification, risk propagation, safety assessment, defense control, and cascading  ...  To address this problem, a modeling method for the coupling relations of microgrid CPS driven by hybrid spatiotemporal events is proposed in the present work.  ...  The spatiotemporal deduction process of the attack data flow is as follows.  ...

Optimizing spatial allocation of COVID‐19 vaccine by agent‐based spatiotemporal simulations

Shuli Zhou, Suhong Zhou, Zhong Zheng, Junwen Lu
2021 GeoHealth  
It simulated spatiotemporal process of COVID-19 transmission in a realistic urban context.  ...  We proposed an integrated spatial model of agent-based model and SEIR (susceptible-exposed-infected-recovered).  ...  Further, since the agent-based simulation is ultimately embodied in the space aspects, it reveals that spatial optimization plays a greater role in vaccine allocation.  ...

Consciousness as Recursive, Spatiotemporal Self-Location

Frederic Peters
2008 Nature Precedings  
Cognition computes action-output in the midst of ongoing movement, and consequently requires a constant self-locating spatiotemporal reference frame as basis for these computations.  ...  structures ongoing spatiotemporal self-location computations as i-here-now.  ...  For purposes of management, that structure is configured in terms of the moment-to-moment spatiotemporal location of the agent in relation to the environment.  ...
