Circuit breakers are important equipment to control the energy distribution and fault isolation in power grid. With the development of the power grid in China, the evaluation of health status of circuit breaker in operation becomes an important part of the operation management. A number of studies have been made on the evaluation of circuit breaker health status, but are mostly limited to interpretation...
some urban corridors see serious congestion during rush hours, but travel time is still predictable; while others may not suffer from heavy congestion but exhibit high travel time unreliability. The latter case usually makes motorists more frustrated. Moreover, empirical studies show that the level of unreliability varies over time of day. Using the collected travel time and travel speed data, this...
Peripheral arterial disease and atherosclerosis are common complications in patients with type 2 diabetes or with both diabetes and end-stage renal disease. Lower-limb peripheral arterial disease and hemodialysis (HD) vascular access stenosis are highly prevalent in HD patients; in particular, progressively narrowed vascular access and suboptimal dialysis blood flows are the major issues. In this...
This paper proposes a novel method for peripheral vascular occlusive disease (PVOD) estimation in diabetic foot using a fractional-order chaotic system (FOCS). Photo-plethysmography (PPG) is a non-invasive technique for detecting blood volume changes in peripheral arteries. Bilateral PPG signals gradually become asymmetry on the right-site or left-site transit time and pulse shape with PVOD severity...
As generalization ability of neural network was restricted by overfitting problem in the network’s training. Early stopping algorithm based on fuzzy clustering was put forward to solve this problem in this paper. Subtractive clustering and Fuzzy C-Means clustering (FCM) were combined to realize optimal division of training set, validation set and test set. How to realize this algorithm in backpropagation...
