There have been a variety of constant on-time (COT) controllers for dc power converter applications reported in recent years <xref ref-type="bibr" rid="ref1 ref2 ref3 ref4">[1]</xref>–<xref ref-type="bibr" rid="ref5">[5] </xref>. In this paper, a novel adaptive quasi-constant on-time current-mode control scheme is proposed and implemented...
For nonlinear problem in target tracking, on the basis of maneuver turn model, the AGIMMCKF-algorithm is proposed, which is a variable multiple model algorithm that combined cubature kalman filter (CKF) with adaptive grid (AG). CKF as a filter, the algorithm using grid center and the adjustment of the minimum distance between grid to change turn model set adaptively so as to effectively track targets,...
This paper is concerned with event clustering for short text streams, which aims to divide constantly arriving short texts into several dynamic event-based clusters. A widely adopted approach is based on the Vector Space Models (VSMs) such as bag of words. However, these models have limitations in that not only the semantic relationships between words are largely ignored, the term weighting may also...
Just in a few decades, the rapidly developed wireless networks and the intelligent information systems popularity had so dramatically changed our daily lives. From the view of the ubiquitous computing, which context and ambient awareness [5]respected omnipresent computing allow users to receive the location corresponded and suitable information at any time in anywhere through portable computing device[6],...
