In this paper, first we give conditions under which the weighted mean matrix operator is bounded on the weighted Hardy spaces, and we characterize the spectrum of the weighted mean matrix operator acting on some sequence spaces. Then we investigate eigenvectors of weighted mean matrix operator.
This paper investigates the application of multisensor fault feature extraction and fuzzy-logic based clustering for the condition monitoring of bearing. Multiple independent sensors on an electric motor drive system provide valuable early indication of a fault, and can be effectively utilized to perform high reliable and optimal fault detection. Through utilizing common sensors including current...
This paper presents fault detection and its analysis for permanent magnet assisted synchronous reluctance motor (PMa-SynRM). The PMa-SynRM has been increasingly studied for critical service application where high efficiency and reliability is required in industry. However, the research on the fault in a PMa-SynRM has been limitedly studied, and no study on the eccentricity fault diagnosis for multiphase...
In this paper, we propose a channel and queue aware cross-layer algorithm for allocating power and sub-carriers to users in Orthogonal Frequency Division Multiple Access (OFDMA) networks. Our algorithm uses utility to build a bridge between the physical layer and upper layers and also to balance the efficiency and fairness of the radio resource allocation. The objective is to develop a method based...
