Research ArticleOpen accessIn the abstractAutomated 3D Particle Field Extraction and Tracking System Using Digital in-line HolographyHesham EldeebDigital holography for 3D particle field extraction and tracking is an active research topic. It has a great application in realizing characterization of micro-scale structures in microelectromechanical systems (MEMS) with high resolution and accuracy. In-line configuration is studied in this study as the fundamental structure of a digital holography system. Digital holographic approach, not only eliminates wet chemical processing and … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 6,539 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHybrid Adaptive Filters for Dynamic Mass Measurement of Moving Objects on Flexible PlatformsSergio Bimbi Junior, Flavio Celso Trigo, Agenor de Toledo FleuryDynamic mass measurement of moving objects on flexible platforms remains a significant challenge due to mechanical vibrations, structural flexibility, and the inherently low Signal-to-Noise Ratio (SNR) of strain gauge sensors. Traditional analog filtering approaches, such as Tow– Thomas active filters, exhibit limitations since gain stages propagate and may even amplify intrinsic noise, compromising metrological accuracy. This work proposes a hybrid … …American Journal of Engineering and Applied Sciences, Vol. 19, Issue 1 · 22 Apr 2026 · 2,669 accessesView PDFCite

DevarajanProblem statement: Machine vision system is based on digital image processing and is found to be the best sensor detection as its operation is similar to the human eye. The purpose of machine vision is the desire to provide real time machines with visual abilities. Approach: A real time system is developed and is interfaced with the mechanical structure to … …Journal of Computer Science, Vol. 8, Issue 4 · 2 Feb 2012 · 7,081 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCyclic Instability of Shape-Memory Alloys in Seismic Isolation SystemsFilipe Amarante dos Santos, Corneliu Cismasiu, Francisco Braz FernandesShape-memory alloys are being progressively introduced as kernel components in seismic retrofitting devices for civil engineering structures. In order to control the instability associated with the first mechanical cycles, a training procedure is usually implemented, which stabilizes the superelastic behavior of the alloy. This paper addresses the characterization of the cyclic behavior of an austenitic NiTi alloy with emphasis on … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 7 Jan 2018 · 6,856 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordThe Yield of the Thermal EnginesNicolae Petrescu, Florian Ion Tiberiu PetrescuThis paper presents an algorithm for determining the dynamic parameters of the main classic mechanism of internal combustion engines. It shows the distribution of forces (on the main engine mechanism) to internal combustion engines. With these forces and together with the kinematic coupling speeds, the efficiency of the thermal engine is determined. The method applies separately for two distinct situations: … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 14 May 2019 · 6,194 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDynamics at Classical DistributionRelly Victoria Virgil PetrescuClassical distribution is the most used in rigid memory mechanisms adapted to four-stroke internal combustion engines such as Otto or diesel, as it was designed by Otto more than 150 years ago, without essential changes from its conception and up today. Since it was not yet possible to introduce the electric car to the industrial scale and today we have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 26 Apr 2019 · 6,400 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordMechanisms With Rigid MemoryRelly Victoria Virgil PetrescuAlong with gears, distribution mechanisms are the most widely used mechanical transmissions used over the past 300 years and will continue to be the most widespread in all industrial fields but also in other technical areas. For this reason, it was considered necessary this work, which tries to add a brick to the permanent construction of rigid memory mechanisms used … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 19 Jul 2019 · 6,167 accessesView PDFCite
