Research ArticleOpen accessIn the keywordsPlasma Beams Free Vibration Ivestigation using the Boubaker Polynomials Expansion SchemeK. BoubakerProblem statement: In the present study, plasma beams free vibration frequencies alteration has been investigated through an original protocol. Approach: The Boubaker Polynomials Expansion scheme BPES has been performed for deducing and ranging the dimensionless frequencies of the beam vibrations. Results: Natural frequencies of the plasma beam have been estimated for given parameters values. Conclusion: Yielded results have been compared … …Physics International, Vol. 2, Issue 2 · 25 Jan 2012 · 7,986 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid 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 · 2,655 accessesView PDFCite
EditorialOpen accessIn the abstractVolume 1: First Steps for SGAMRChiara Bedon, Mario D’Aniello, Flavio StochinoSummer 2017 is approaching when the International Journal of Structural Glass and Advanced Materials Research starts to walk and the “Volume 1” contains its first outcomes (Bedon et al., 2017). It is worth of interest that the attention of the contributors is on glass…. but not only,… and this represents a promising step for the journal growth and evolution. In … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 28 Aug 2020 · 6,331 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamics 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 · 6,394 accessesView PDFCite
Review ArticleOpen accessIn the abstractRomanian Engineering "On the Wings of the Wind"Relly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThe presented study proposes a commemoration of the main artisans of the Romanian and world aviation, from its beginnings to the day. Very briefly are brought to the forefront, the main inventors of flying machines and equipment that have lived here in the Romanian territory and have contributed substantially to the development of any type of flight. We will talk … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 9,408 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeorge (Gogu) ConstantinescuRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.George (Gogu) Constantinescu (October 4, 1891 - December 11, 1965) was a Romanian scientist and engineer, often considered to be one of the most important Romanian engineers. He was responsible for creating a new field of mechanics, called "sonicity," which describes the transmission of energy through vibrations in fluid or solid bodies. He applied the new theory to numerous inventions: … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 5 Dec 2017 · 8,571 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability and Ergonomic Design Features of Tractor Mounted Hydraulic Elevator for Coconut HarvestingKishor Purushottamrao Kolhe, Ashok G. Powar, Amit D. Dhakane, Sham H. MankarProblem statement: The most important design criterion of mechanized device was safety; safety comprises both the safety of operator and safety of maintenance personnel. Failures and safety of harvesting platform of Tractor Mounted Hydraulic Elevator (TMHE) powered by tractor PTO was tested by finite element method for the mechanical harvesting of coconut orchards using digital ergonomic hart rate meter.

Research ArticleOpen accessIn the abstractTesting and Performance Evaluation of Tractor Mounted Hydraulic Elevator for Mango OrchardKishor P. Kolhe, Bhaskhar B. JadhavProblem statement: The harvesting and pruning of horticultural crops is quite difficult due to their tallness. There are small hand tools available for harvesting and pruning. But these tools of harvesting and pruning are restricted due tree height, unavailability of trained labours for climbing and cost of operation etc. The mechanized machines are available; these are heavy and costly and … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 26 Mar 2011 · 8,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Vibrations in Switched Reluctance Motor DrivesS. Balamurugan, R. ArumugamThis study discusses a simple algorithm for estimation and reduction of Vibrations in a Switched Reluctance Motor (SRM) using magnetic circuit simulation in MATLAB/SIMULINK Environment. A Non-linear model is developed using magnetic circuit equations, wherein non-linearity is added using a inductance profile with back EMF. Dynamic characteristic of the SRM is simulated and the same is being verified experimentally. In … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,826 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordContributions to the Synthesis of Fixed Axle Gears by Avoiding the Interference PhenomenonRelly Victoria Virgil PetrescuIt can be seen that the minimum number of teeth required to avoid interference for the standard pressure angle, normally on the alpha0 = 20° decomposition circle, is 13, corresponding to a transmission ratio i = 1 and increases with the transmission ratio i reaching to the maximum value of 18 teeth for i>100. For normal transmission ratios, values ranging … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 21 May 2019 · 6,488 accessesView PDFCite
