BACKGROUND Community health workers (CHWs) are recommended to screen for acute malnutrition in the community by assessing mid-upper arm circumference (MUAC) on children between 6 and 59 months of age. MUAC is a simple screening tool that has been shown to be a better predictor of mortality in acutely malnourished children than other practicable anthropometric indicators. This study compared, un...

Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...

Face detection is one of the important issues which nowadays many communities deal with it and beside, faces recognition is one of the most important areas of research in most of the industrial and research centers. Three main pillars has been considered in face detection which are: classified as the skin and non-skin color, design templates for face, and feature extraction from face images ena...

purpose: to report a relatively rare case of familial exudative vitreoretinopathy (fevr). patient and findings: a 13-year-old boy referred with decreased visual acuity of both eyes, specially right eye from 6 years ago. he had several ophthalmologist and optometrist visits and spectacle prescription without any improvement of vision. best corrected visual acuity (bcva) was 25 cm of count finger...

Background: Circoviruses are small, non-enveloped, single stranded DNA viruses. There is scarce information about these agents in non-psittacine birds. Aims: It is attempted to detect and characterize circoviruses in non-psittacine birds. Methods: Forty-five samples were collected from different non-psittacine species belonging to seven avian o...

Intrusion Detection in Mobile Ad Hoc Networks. (May 2004) Bo Sun, B.S., Nanjing University of Posts & Telecommunications; M.S., Beijing University of Posts & Telecommunications Chair of Advisory Committee: Dr. Udo W. Pooch Most existent protocols, applications and services for Mobile Ad Hoc NETworks (MANETs) assume a cooperative and friendly network environment and do not accommodate security. ...

This paper presents a new BIST(Built-in Selftest) method for A/D converters. The method characterizes the static parameters of A/D converter like offset, gain, INL(Integral Non-linearity) and DNL(Differential Non-linearity). It uses a ramp signal as a test stimulus and consists of three detectors – a transition detector, an INL detector and a DNL detector. The transition detector checks the cod...

We show explicitly that massive, Abelian, vector – just like (properly defined) massive tensor – fields limit smoothly to their massless, gauge, versions: they emit only maximal helicity radiation and mediate Coulomb/“special relativistic Newtonian”, forces between their (conserved) sources. Our main motivation, though, is to show that LIGO’s gravitational wave detection probably cannot directl...

Canada's third-generation HFSWR forms the foundation of a maritime domain awareness system that provides enforcement agencies with real-time persistent surveillance out to and beyond the 200 nautical mile exclusive economic zone (EEZ). Cognitive sense-and-adapt technology and dynamic spectrum management ensures robust and resilient operation in the highly congested High Frequency (HF) band. Dyn...
