Training on measurements to determine the characteristics of the three-phase electrical system is very useful for a deep knowledge of the theoretical aspects. Laboratory sessions for measurement by using advanced technologies must be performed. Two implemented tools are presented. The first one fulfils some requirements: it uses a virtual instrument, will be used in distance learning sections a...

Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility service companies the opportunity to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. The AMR system consists of thre...

background: in neonatal intensive care units (nicu) different sound intensities and frequencies are produced from different sources, which may exert undesirable physiological effects on the infants. the aim of this study was to determine the noise level and its sources in the nicu and neonatal ward of al-zahra hospital of rasht, iran. methods: in this descriptive cross-sectional study, the inte...

Meter reading is an important part of billing system for residential and commercial buildings. This often does not reflect the exact or true electricity consumption of such buildings, resulting in an inefficient bill mainly due to human errors. Thus, it is essential to have n efficient and effective system for this measurement purposes. This project is about the design and construction of a per...

The assembly precision of the magnetic system an electromechanical meter is important guarantee for measurement accuracy meter. large gap between two poles key point that affects and also difficulty manufacturers face. In this paper, controllable factors affect a are selected by performing orthogonal experiment, process analyzed, noise selected; design achieved using inner outer array used to e...

Background: In Neonatal intensive care units (NICU) different sound intensities and frequencies are produced from different sources, which may exert undesirable physiological effects on the infants. The aim of this study was to determine the noise level and its sources in the NICU and neonatal ward of Al-Zahra Hospital of Rasht, Iran. Methods: In this descriptive cross-sectional study, the inte...

Background and Purpose—This study aimed to assess the effectiveness of gait training using an electromechanical gait trainer with or without functional electrical stimulation for people with subacute stroke. Methods—This was a nonblinded randomized controlled trial with a 6-month follow-up. Fifty-four subjects were recruited within 6 weeks after stroke onset and were randomly assigned to 1 of 3...

Abstract Vibration comfort is an important indicator for evaluating escalator riding experience. The measuring principle of vibration step and armbands was analyzed. calculation methods acceleration extraction, frequency meter weight, root mean square (RMS) vector sum were summarized. A wireless triaxial data acquisition module developed based on micro-electromechanical system (MEMS) sensor, MC...
