An intelligent conductivity meter based on MSP430F149 microcontroller was proposed in this paper. The intelligent conductive meter was composed by MSP430F149 microcontroller and its peripheral circuits, bipolar pulse excitation circuit and waveform transform circuit. The MSP430F149 was chosen to control the generation of bipolar pulse excitation signal and take temperature compensation. It adop...

Resistance to DSCG in acute asthma is greater therefore, than to salbutamol. However, clinical observation suggests that resistance to beta-2 stimulants does also increase with severity of the attack. It would appear probable that only when severity exceeds the point at which measurements can be made with a peak flow meter does resistance to salbutamol become pronounced. Although placebo effect...

Recent trends in electric meter is based on Global System for Mobile Communication(GSM), Radio Frequency Identification(RFID), Remote wireless energy measurement from meter. But none have turned to solve the problems related to power demand. In this paper, we propose a solution to solve the problems associated with power demand by designing an electric meter that efficiently handles the power c...

This paper focuses on the surface contamination control of slightly contaminated property after the Fukushima nuclear accident. The operational level for the unconditional release of contaminated properties is calculated in counts per minute (cpm) to enable the use of a typical Geiger-Muller (GM) survey meter with a 50-mm bore, on the basis of the surficial clearance level of 10 Bq cm(-2) for (...

Simple Network Management Protocol version 3 is an extension of earlier versions addressing security and administration features of SNMP. SNMPv3 has additional features like different message format and defines new management information bases (MIB) for security, configuration, notification, view-based access control and proxy forwarding. Simulation of SNMPv3 traffic flow meter MIB has been car...

Four-terminal impedance meters based on pseudo-bridges yield unexpected uncertainties when using high-contact-impedance electrodes. Adding a front-end amplifier to the impedance meter and rearranging the connection of the meter terminals overcome the contact impedance problem. However, because the compensation provisions in the instrument are meant to compensate only impedance residuals of test...

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...
