The paper utilizes a novel battery model based on the electrical features of LiFePO4 battery, because Kalman filter algorithm(KF) is largely dependent on system model. Measurements of battery state are easily disturbed by colored noise which is high relevance in working condition, and the paper studies that the system noise satisfy one-order AR model. The paper proposes an adaptive extended Kalman...
Online social media networks play important roles for people to share opinions, communicate with others. One of important features behind these activities is trust. This paper investigates the trust model in Online social media networks. Considering the interaction between two users and the reputation in the social networks, this trust model gives a definition about the trust value between two users...
As the symbol of the partition clustering method, K-Means is well known and widely used in many fields for the easily implemented and high efficiency. However, the initial center problem may affect the final cluster result, sometimes the final cluster result might contain some empty clusters. In this paper, a new K-Mean initialization method is proposed which combines the statistical information and...
This paper describes a current sharing technique for digitally controlled multiphase buck DC-DC converters. The effective duty cycle mismatches and resistance mismatches are digitally compensated to achieve equal current sharing without sensing currents. Effects of various non-idealities on the current sharing performance are discussed. Experimental results are shown for a four-phase synchronous buck...
Independent component analysis (ICA) has proven useful for the analysis of functional magnetic resonance imaging (fMRI) data. In this paper, we compare the performance of three ICA algorithms and show the importance of taking sample correlation information into account. The three ICA algorithms are Infomax, the most widely used algorithm for fMRI analysis, entropy bound minimization (EBM) that adapts...
Target signal is measured by acoustic sensor with the character of time-delay and bearing-only. The problem of target locating and time-delay registration can be solved by composing sensor network. A passive acoustic sensor network time-delay probabilistic localization algorithm is presented in this paper. Firstly, two sensor measures can be chosen that intersection angle is closed to 90?? to get...
