Research ArticleOpen accessEvery word in the titleHybrid 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
Research ArticleOpen accessEvery word in the titleq-Deformed Statistics from Position-Dependent Mass Schrödinger EquationaJesus Morales Rivas, Jose Juan Peña Gil, J. García RaveloAn algebraic approach is used to obtain the canonical form of the position-dependent mass Schrödinger equation from where a couple of canonical quantum variables, the q-deformed operators for the position xq, and the hermitian linear momentum operator pq are derived. In this q-deformed coordinate space, the commutator remains invariant namely [xq, pq] = iħ. By taking advantage of these q-deformed … …Journal of Mathematics and Statistics, Vol. 19, Issue 1 · 15 Sep 2023 · 5,191 accessesView PDFCite

Literature ReviewOpen accessEvery word in the titleDevelopment of Azithromycin Resistance in Streptococcus pneumoniae in the Setting of Trachoma Mass Drug Administration: A Systematic ReviewNazia Khan, Barbara Lachana Onen, Robin Hilder, Robin BaileyTrachoma is a blinding eye disease caused by the bacterium Chlamydia trachomatis. The current global elimination of trachoma initiative includes the use of mass drug distribution of azithromycin in areas where the prevalence of follicular trachoma is >10% in children aged 1-9 years. This study aims to investigate the high quality evidence of whether mass drug administration for trachoma causes … …American Journal of Infectious Diseases, Vol. 16, Issue 3 · 24 Jul 2020 · 7,596 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Multiple Tuned Mass Damper for Passive Control of Structures by Cuckoo AlgorithmHamid Jafari Nia, Amir Hossein Heidari, Hamid Reza Babaali, Kaveh Ostad-Ali-AskariAdjustable mass dampers are recently used to reduce seismic vibrations of engineering structures. Function of these types of systems requires a suitable setting of their parameters. In this study, a practical method to design Multiple Tuned Mass Dampers (MTMD) has been proposed to minimize the maximum displacement of roof, acceleration of roof and TMDs displacement to reduce the seismic response … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 16 Jul 2020 · 7,392 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Hypothesis Which Supports the Possibility of the Existence of Dark Matter with Negative MassFlorian Ion Tiberiu PetrescuThe paper presents an algorithm for calculating the negative mass of an atomic electron, a fact that from a physical point of view shows the possibility of the existence of the matter with the negative mass that could constitute the dark matter that separated from the normal matter with the positive mass due to the huge masses of different matter … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 23 Jan 2020 · 7,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMeasurement of Gas-Phase Mass Transfer Coefficients in a Humidification Column through Random PackingMasoud Khorasani, Morteza Zivdar, Farshad Fashchi Tabrizi et al.Packed columns are an important part of the broad selection of mass and heat transfer equipment. Nowadays, the use of packed columns is increasing, which is because of its lower pressure drop, higher capacity and higher mass transfer in comparison to tray columns. The experiential tests and the hypothetical analysis display that the chemical dehumidification of air by hygroscopic salt … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Jul 2019 · 8,028 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDerivation of Potentially Important Masses for Physics and Astrophysics by Dimensional AnalysisDimitar ValevThe Hubble constant has been added in addition to the three fundamental constants (speed of light, gravitational constant and Planck constant) used by Max Planck, for derivation of the Planck mass by dimensional analysis. As a result, a general solution is found for the mass dimension expression m = γp m0, where m0 ≡ mp is the Planck mass, γ … …Physics International, Vol. 8, Issue 1 · 25 Oct 2017 · 9,138 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFast Food Consumption and Body Mass IndexVasanthakumar N. BhatFast food consumption has been considered a major cause of obesity all over the world. The purpose of this paper is to examine the association between the average frequencies of eating a meal from a fast-food restaurant per week and Body Mass Index (BMI). Our analysis based on a nationwide survey of Americans indicates that a meal from a fast … …Journal of Social Sciences, Vol. 12, Issue 3 · 13 Jul 2016 · 8,928 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimations of Neutrino and Graviton Masses by a Phenomenological Mass Relation for Stable ParticlesDimitar T. ValevThe ratio between the proton and electron masses was shown to be close to the ratio between the shortest lifetimes of particles, decaying by the electromagnetic and strong interactions.
