Life prediction of bearing is the urgent demand in engineering practice, and the effective bearing degradation assessment technique is beneficial to predictive maintenance. This paper presents an application of an important Bayesian machine learning method named Gaussian Process Regression (GPR) for bearing degradation assessment. The Gaussian Process (GP)(More)
Remaining useful life (RUL) prognosis of bearing is an enabling step for efficient implementation of condition based maintenance. Through intelligent tracking of features, status of bearing can be monitored and a rough RUL can be calculated. This paper presents an application of an important Bayesian machine learning method named Gaussian Process Regression(More)
In many scenarios, sensor nodes have to rely on a limited supply of energy (using batteries). To support long lifetime of wireless sensor networks (WSN), an energy-efficient way of operation of the WSN is necessary. In this paper, we propose a new controlled layer deployment (CLD) routing protocol to guarantee coverage and energy efficiency on a sensor(More)
—A novel high-gain, dual-band antenna covering IEEE 802.11a/b/g bands is presented in this letter for wireless local area network (WLAN) applications. The antenna is composed of a fork-like monopole, a rectangular ring, and a miniaturized rectangular patch. The backside radiation of the antenna is effectively reflected back by a rectangular metal, so(More)
Multifunctional Biotin-PEG-b-PLL(Mal)-peptide-DOX polymeric micelles were prepared to selectively eliminate cancer cells. The micelles were able to enhance cancer cell uptake via the receptor-mediated endocytosis and respond to the stimulus of cancer cell excessive secreted protease MMP-2 to release the anticancer drug and induce apoptosis of cancer cells(More)
This letter introduces a novel passive beamformer which uses Bridge function sequence as spreading sequence weights for every antenna element. The set of Bridge function sequences have zero correlation zones (ZCZs) in their cross-correlation functions (CCFs). Due to the ZCZ properties of Bridge function sequences, the introduced passive beamformer features(More)
