BACKGROUND Recent trends in global vaccination coverage have shown increases with most countries reaching 90% DTP3 coverage in 2008, although pockets of undervaccination continue to persist in parts of sub-Saharan Africa particularly in the urban slums. The objectives of this study were to determine the vaccination status of children aged between 12-23 months living in two slums of Nairobi and ...

Abstract In this work, we present a new algorithm for human action recognition on raw depth maps. At the beginning, each class train separate one-against-all convolutional neural network (CNN) to extract class-specific features representing person shape. Each class-specific, multivariate time-series is processed by Siamese multichannel 1D CNN or determine actions. Afterwards, nonzero pixels sha...

Evaluating whole-body motion is challenging because of the articulated nature skeleton structure. Each joint moves in an unpredictable way with uncountable possibilities movements direction under influence one or many its parent joints. This paper presents a method for human quantification via three-dimensional (3-D) body joints coordinates. We calculate set metrics that movement considering wi...

The focus of this work is to determine at which threshold can the results for both plane and spherical wave incidence assumptions either converge or deviate when performing multiple diffraction attenuation calculations. analysis has been carried out—for various millimeter-wave frequencies, inter-obstacle spacings, angles incidence—by employing a pair two-dimensional (2D) hybrid formulations bas...

In this paper we present a semantic architecture that was employed for processing two different SemEval 2007 tasks: Task 4 (Classification of Semantic Relations between Nominals) and Task 8 (Metonymy Resolution). The architecture uses multiple forms of syntactic, lexical, and semantic information to inform a classification-based approach that generates a different model for each machine learnin...

Ultra-wideband (UWB) technology has developed rapidly over the past several years. This technology is especially attractive in high-data-rate and short-range wireless communications. These applications make UWB technology suitable for indoor mobile communication applications, such as wireless personal-area networks (WPAN). This interest has motivated the study of the propagation of the UWB sign...
