More recently, with the increasing demand of web services on the World Wide Web used in the Internet of Things (IoTs), there has been a growing interest in the study of efficient web service quality evaluation approaches through the use of prediction strategies to obtain accurate quality-of-service (QoS) values. The unpredictable network environment imposes(More)
Wireless sensor networks (WSNs) as one of the key technologies for delivering sensor-related data drive the progress of cyber-physical systems (CPSs) in bridging the gap between the cyber world and the physical world. It is thus desirable to explore how to utilize intelligence properly by developing the effective scheme in WSN to support data sensing and(More)
With the modern industrial development, there has been an increasing demand for selecting qualified web services to construct the personalized Industrial Internet of Things (IIoT) applications with the support of cloud computing technologies. Meanwhile, the task of predicting large-scale quality of service (QoS) values plays an important role in achieving(More)
Wireless sensor network (WSN) is a typical application of Ad hoc network in autonomous system (AS). It has attracted considerable attention in the past. Recent years have witnessed a growing interest in the study of localization algorithm for WSN. Self-localization of nodes is one of the key technologies for application of WSN. The localization accuracy is(More)
Theoretical aspects of the decorrelation property of the discrete wavelet transform when applied to stochastic processes have been studied exclusively from the increasing-domain perspective, in which the distance between neighboring observations stays roughly constant as the number of observations increases. To understand the underlying data-generating(More)
Recently, there has been an ever-increasing interest in the study of data-driven analytics to predict hidden dangers in the cloud service-based coal mine production, with the purpose of the prevention of possible accidents. In this paper, to achieve the above prediction, a machine learning algorithm based on the single-hidden layer feed forward network(More)
Investigation of ohmic contact between iridium (Ir) film and hydrogen-terminated single crystal diamond has been carried out with annealing temperature from 300 to 600 °C in argon (Ar) and hydrogen ambient. Electrodes were deposited on hydrogen-terminated single crystal diamond by electron beam evaporation technique, and specific contact resistivity has(More)
