We propose a sensing system comprising large network of tiny, battery-less, Radio Frequency (RF)-powered sensors that use backscatter communication. The an entirely passive technique to 'sense' the parameters wireless channel between themselves. Since material properties influence RF channels, this fine-grain can uncover multiple both at scale and fine spatial resolution. In paper, we study fea...

In order to scale back the life cycle costs of an establishment from construction maintenance, it is very effective monitor structural health a structure. At present, maintenance and integrity checks on structure require personnel entry into normally inaccessible areas perform necessary non-destructive inspections. This paper discusses implementation budgeted, battery-powered based collision av...

A primary motivation for the development and implementation of structural health monitoring systems, is prospect gaining ability to make informed decisions regarding operation maintenance structures infrastructure. Unfortunately, descriptive labels measured data corresponding health-state information structure interest are seldom available prior a system. This issue limits applicability traditi...

the reference charts for mid upper arm (muac), chest (chc) and head (hc) circumferences of a cohort of 317 healthy infants (153 boys and 164 girls) born in shiraz (southern iran) and monitored from birth for 2 years are presented. centiles for muac and hc lie below the netherlands and us subjects respectively. however, there is no suggestion of ill health for iranian subjects. the use of locall...

Structural health monitoring is a process of evaluating and ensuring the safety and integrity of structural systems by converting sensor data into structural health monitoring information. The first and most important objective of structural health monitoring is to ascertain with confidence if damage is present or not. The idea is to characterize only the normal condition of a structure and the...
