A smart wearable electrocardiographic (ECG) processor is presented for secure ECG-based biometric authentication and cardiac monitoring, including arrhythmia and anomaly detection. Data-driven Lasso regression and low-precision techniques are developed to compress the neural networks by 24.4X. The prototype chip fabricated in 65 nm LP CMOS consumes 1.06 μW at 0.55 V for real-time ECG authentication...
In recent years, disastrous earthquake assault the human frequently. The evaluation and estimate of the loss and damage in seismic disaster is an important factor for earthquake emergence and post-earthquake reconstruction decision-making. This paper synthetically designs a set of disaster real-time evaluation system based on the seismic networking of things. This paper firstly collects real-time...
Wireless sensor network (WSN) has been considered to be the next generation paradigm of structural health monitoring (SHM) systems due to its low cost, high scalability and flexibility. However, some inherent limitations of WSN such as low-bandwidth wireless communication, limited resources on wireless sensor nodes, must be addressed to meet the generally high requirements of SHM. Distributed in-network...
PCCP is usually used throughout many water and wastewater utilities as critical mains with high flow rates, sudden failures can have significant negative consequences. The world has experienced a number of failures of prestressing concrete cylinder pipe (PCCP) lines and as a result during the past ten years, much attention has been focused on reliably assessing the condition of PCCP mains. In this...
