In this paper, we describe and evaluate an activity recognition system using a single 3-axis accelerometer and a barometric sensor worn on a waist of the body. The purpose of this work is to prevent child accidents such as unintentional injuries at home. In order to prevent child accidents in the home and reduce efforts of parents, we present a new safety management system for babies and childr...

This paper investigates the extent and ways in which childhood family and neighborhood quality influence later-life health outcomes. The study analyzes the health trajectories of children born between 1950 and 1970 followed through 2005. Data from the Panel Study of Income Dynamics (PSID) spanning four decades are linked with information on neighborhood attributes and school quality resources t...

BACKGROUND We present a series of simulation studies that explore the relative performance of several phylogenetic network approaches (statistical parsimony, split decomposition, union of maximum parsimony trees, neighbor-net, simulated history recombination upper bound, median-joining, reduced median joining and minimum spanning network) compared to standard tree approaches, (neighbor-joining ...

Richard P. Lippmann Lincoln Laboratory, MIT Room B-349 Lexington, MA 02173-9108 Eight neural net and conventional pattern classifiers (Bayesianunimodal Gaussian, k-nearest neighbor, standard back-propagation, adaptive-stepsize back-propagation, hypersphere, feature-map, learning vector quantizer, and binary decision tree) were implemented on a serial computer and compared using two speech recog...

In this paper, we study the consensus formation over a directed hypergraph, which is an important generalization of standard graph structure by allowing possible neighbor-dependent synergy. The proposed model situated in social dynamics providing key features including observer effect and bounded confidence. Under minimal siphon condition hypergraph (Petri net), show that global can be reached ...

this study highlights the costs and benefits of indigenous beef cattle fattening schemes in shinyanga urban and kishapu districts in tanzania. specifically, in this study the net profit (np) for fatteners between beef cattle fattening schemes has been determined. the schemes were divided into two main categories, scheme 1 in which the animals were fed on cottonseed hulls (cshl) based diets and ...
