This paper describes a novel low-cost tire pressure monitoring system (TPMS) for bicycles. The is based on battery-less near field communication (NFC) tag that integrates sensor, which placed between the and inner tube. uses no battery since energy obtained from magnetic induced by reader in order to establish communication. can be read any NFC-enabled such as smartphone. sensor force-sensing r...
Recent advancements in power electronics technology evolves inverter fed electric motors. Speed signals and rotor position are essential for controlling an motor accurately. In this paper, the sensorless speed control of surface-mounted permanent magnet synchronous (SPMSM) has been attempted. SPMSM wants a digital its precise working. Hence, study incorporates fifteen level to SPMSM. A sliding ...
Carbon paste electrode was modified by disodium 2,4-diamino-7-methylbenzo[g] pteridine-5,10-dioxide to fabricate a sensor for potentiometric determination of vanadyl ion (VO2+) in aqueous medium. The new ligand was synthesized in three steps with high yield. The optimal composition of the carbon paste was made of graphite powder (64.5%), ionophore (16.6%), paraffin oil (17.8%), a...
A novel potentiometric ion-selective PVC membrane sensor for analysis of atorvastatin (AT) in pharmaceutical preparations based on atorvastatin-(tetraphenyl borate), (AT-(TPB)2) as sensing element, tetraphenyl borate as additive and tris-2-ethyl-hexyl phosphate (TOP) as plasticizer solvent was prepared. The electrode shows a good Nernestian response over the concentration range of 0.09–5586 µ...
adequate coverage is one of the main problems for distributed wireless sensor networks and the effectiveness of that highly depends on the sensor deployment scheme. given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. in this paper, we apply fuzzy logic system to...
