TL;DR: In this article , an ensemble learning algorithm is proposed for automatic atrial fibrillation (AF) detection from single lead ECG recordings collected by wearable devices, which includes two modules: denoised 1-D time series (ECG), time-frequency spectrum and Poincare plot.

TL;DR: When the data of panorama and whole life cycle is big enough and the system component structure and the static data and dynamic data of each individual are recorded, the big data can integrally depict the complicated system and the emerging phenomena.

TL;DR: In this paper , a DEA model of transportation infrastructure efficiency evaluation under Digital Twins technology is established, and the traffic flow data of a certain road section in Zhenjiang City (J11 City) is simulated and predicted by using the Long Short-term Memory (LSTM) traffic flow prediction model.

TL;DR: It is analyzed quantitatively that adjusting the adjustable nozzle ring can keep the output power stable, widen the flight envelope, and improve the stability of the environmental control system.

TL;DR: In this article , the authors proposed an authentication protocol for the MEC environment, which stipulates secure and efficient communication for all of the intended entities, while during its execution user anonymity remains intact. And the security properties of the protocol that it offers resistance against impersonation, session key computation and forward and backward secrecy attacks.
