Research ArticleOpen accessEvery word in the titleTransient Response of a Novel Displacement Transducer for Magnetic Levitation SystemMrunal Deshpande, Badrilal MathurProblem statement: In magnetic levitation system, position sensors are used to obtain a voltage proportional to the position of the suspended object. This is an essential feedback signal for stabilizing the system. These sensors make the system clumsy and prone to failures. To eliminate any physical attachment on the levitated object for the purpose of measuring its displacement, a novel … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 5 Oct 2011 · 7,235 accessesView PDFCite

Rafiqul IslamProblem statement: The design of Capacitance to Voltage Converter (CVC) for capacitive sensor transducer was presented. The proposed design will reduce the size, power consumption and supply voltage of the circuit and can be used in high frequency band transducer. Approach: The design was implemented using the Operational amplifier (Op amp) and capacitive network. The circuit was simulated using the … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 8,436 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTransducer for Tension Force Measuring of Strip MaterialsEmad Said AddasiIn winding-up motor drive systems, such as that used in textile industry, it is very important to get a constant tension force for the winding strip material (thread) and to reduce its oscillations. This study recommends a transducer with a special design to be used in the mentioned motor drive systems. By using a piston damper, spring, levers, slider and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDevelopment and Evaluation of Tractors and Tillage Implements Instrumentation SystemS. A. Al-Suhaibani, A. A. Al-Janobi, Y. N. Al-MajhadiProblem statement: Field machines contribute a major portion of the total cost of crop production. Proper selection and matching of farm machinery is essential in order to reduce the cost of crop production. Performance data for tractors and implements are, therefore, essential for farm machinery operators and manufacturers alike. The aim of this study was to develop and evaluate an … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,304 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Modeling Approach for Collision Avoidance in Robotic SurgeryReza Ramezanifard, Javad Dargahi, Siamak Najarian, Farhad Tabatabai GhomsheWe present a new system that can be used in combination with an array of ultrasonic piezoelectric sensors and has application in surgical navigation procedures. Using the proposed assembly, the maneuverability of the surgical tools can be enhanced and the incidence of potentially damaging contact with non-target tissue can be reduced. The emphasis of our work was based on controlling … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,795 accessesView PDFCite
Review ArticleOpen accessIn the abstractJAK Inhibitors for Rheumatoid Arthritis: Assessing Efficacy and Safety in TreatmentAnastasia V. Poznyak, Varvara A Orekhova, Natalia Vladimirovna Elizova et al.Rheumatoid Arthritis (RA) is a chronic autoimmune disease characterized by synovial inflammation, progressive joint destruction, and systemic complications. Dysregulated cytokine signaling through the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway plays a central role in RA pathogenesis, making JAK inhibitors an important therapeutic option. Tofacitinib, baricitinib, and upadacitinib are oral targeted synthetic disease-modifying antirheumatic drugs that interfere with … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 8 Oct 2026 · 412 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Simulation of the Impact of Temperature on Single Point Load Cell using Trnsys 16.0: Measured, Uncompensated and Error Data for Zaria Kaduna StateAlbright A. Edet, Afolayan M. O., Umar A. UmarA load cell is a piece of machined metal called a transducer or load sensor. As a measuring device, the entire framework is prone to the impact of environmental forces which can produce errors in the load cell output. The most significant force or input modifier is high ambient temperature. Typical meteorological year document demonstrates that in March, April, and … …Journal of Mechatronics and Robotics, Vol. 6, Issue 1 · 7 Jun 2022 · 5,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractReinforcing Effect of Strain Gauges on 3D Printed Polymers: An Experimental InvestigationSalvatore Brischetto, Roberto TorreStrain gauges are ordinary transducers for strain measuring; their operation relies on the electrical resistance, which varies as the underlying substrate is subjected to mechanical deformation. The mechanical strain can be obtained by converting the electrical signal through a gauge factor, provided by the manufacturer. It was demonstrated that its values are not unique; it may be influenced by the … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 7,658 accessesView PDFCite
