Along with its methodological development, authorship analysis has expanded in scope to new application areas like authorship profiling and computational sociolinguistics as well as conventional ones like authorship attribution. For these new applications, providing a new interpretation of text through the textual characteristics is as important as improving the classification performance betwe...

The electrochemical oxidation behaviors of NaBH4 on Zn, Zn–MH, and MH (metal-hydride) electrodes were investigated, and an intrinsic direct orohydride fuel cell (DBFC)/battery hybrid power source using MH (or Zn–MH) as the anode and MnO2 as the cathode was tested. Borohydride annot be effectively oxidized on Zn electrodes at the Zn oxidation potential because of the poor electrocatalytic abilit...

Abstract: This paper investigates the detection and classification of fighting and pre and post fighting events when viewed from a video camera. Specifically we investigate normal, pre, post and actual fighting sequences and classify them. A hierarchical AdaBoost classifier is described and results using this approach are presented. We show it is possible to classify pre-fighting situations usi...

OBJECTIVE Using nationally representative data, this study examined the prevalence of very frequent physical fighting (≥12 times per year) among youth in 27 countries and cities. Frequent physical fighting has rarely been reported in the previous literature despite the implications for research and practice. METHODS Analyses were based on the Global School-based Student Health Survey (2003-20...
