Technical ReportOpen accessEvery word in the titleMagnetic Fusion Plasma DriveFlorian NeukartIn the evolving realm of space exploration, efficient propulsion methods are paramount to achieve interplanetary and possibly interstellar voyages. Traditional propulsion systems, although proven, offer limited capabilities when considering longer-duration missions beyond our immediate cosmic vicinity. This study introduces and thoroughly investigates the Magnetic Fusion Plasma Drive (MFPD) propulsion system, a novel fusion-powered propulsion mechanism. Through rigorous theoretical underpinnings and … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 4 Mar 2024 · 7,180 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Evaluation of Adaptive Step-Size Based FxLMS Approach for Active Noise Control in Magnetic Resonance Imaging SystemsI. Juvanna, Uppu Ramachandraiah, G. Muthukumaran et al.Magnetic Resonance Imaging (MRI) scanners emit up to 135 decibels of acoustic noise, which is a major source of discomfort for patients and personnel evaluating them during routine medical scans, necessitating the development of a method to reduce the acoustic noise generated during MRI testing. The goal of this study is to propose a frequency-domain Active Noise Control (ANC) method … …Journal of Computer Science, Vol. 18, Issue 12 · 24 Nov 2022 · 5,503 accessesView PDFCite
Technical ReportOpen accessEvery word in the titleAnalysis of Magnetic Wheel Adhesion Force for Climbing RobotHaydn Welch, Shyamal MondalThis paper describes the aim of designing, building and testing magnetic wheel based an autonomous climbing robot, for use in conjunction with Non-Destructive Testing (NDT) inspection on vertical towers. Through extensive review of previous generations of climbing robot, a hybrid wheel and permanent magnetic adhesion system has been designed and discussed in this paper. Using mathematical modelling and Finite Element … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 31 Aug 2019 · 8,283 accessesView PDFCite
Review ArticleOpen accessEvery word in the titlePermanent Magnetic FluidsNicolae Petrescu, Florian Ion Tiberiu PetrescuA team of researchers at the University of Massachusetts Amherst has accidentally obtained the first magnetized permanent liquid in the world, the droplets of this liquid moving in unison and able to associate in different forms while being manipulated exterior by means of a magnet, according to a new study published in the latest issue of the journal Science, reports … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 22 Aug 2019 · 8,842 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpherical and Improved Helmholtz Coil with High B1 Homogeneity for Magnetic Resonance ImagingSidi M. Ahmed Ghaly, Khalid A. Al-Snaie, Obaidullah Khan MohammadSeveral types of volume RF coils such as Helmholtz pair have been used for Magnetic Resonance Imaging. However, the field uniformity of a coil has always been suffering from a critical issue in imaging accuracy. The presented work is a study and design of spherical and improved radiofrequency Helmholtz coil which produces a high B1 magnetic field homogeneity. This coil … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 22 Dec 2016 · 8,159 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMuon Anomalous Magnetic Moment in a SU(4) ⊗ U(1)N Model Without Exotic Electric ChargesDiego CogolloWe study an electroweak gauge extension of the standard model, so called 3-4-1 model, which does not contain exotic electric charges and it is anomaly free. We discuss phenomenological constraints of the model and compute all the corrections to the muon magnetic moment. Mainly, we discuss different mass regimes and their impact on this correction, deriving for the first time … …Physics International, Vol. 6, Issue 1 · 13 Sep 2015 · 7,687 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSTRINGENT LIMITS FOR THE MAGNETIC FIELD FROM EARLY UNIVERSE DYNAMOS IN RF2 COSMOLOGY WITH TORSIONL. C. Garcia de AndradeBamba et al. (2012) have obtained cosmological magnetic fields in teleparallel torsion theories of gravity that are not compatible with galactic dynamos. This result agrees with previous ones obtained by the author which shows Garcia de Andrade (1999) that anti-dynamo generalised theorem to torsion theories forbides such kind of dynamos to explain galactic magnetic fields of the order of µG. … …Physics International, Vol. 5, Issue 1 · 27 Mar 2014 · 7,854 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleAn Edge Detection Model Based on Virtual Magnetic Field: Application to Digital Color ImagesB. Nsiri, B. BoudaIn computer vision, the edge detection is an essential and difficult problem to study. For this reason, many detectors were developed for gray-level and color images. However, these edge detectors may miss some parts of the edges. In the aim, to deal with this problem, a new approach is proposed. It is based on Virtual Magnetic Field (VMF) in conjunction … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 25 Mar 2013 · 6,435 accessesView PDFCite
