Research ArticleOpen accessIn the keywordsIntegrity Classification Algorithm of Images obtained from Impact Damaged Composite StructuresMahmoud Z. IskandaraniProblem statement: Many NDT systems used for damage detection in composites are difficult to apply to complex geometric structures, also, they are time-consuming. As a solution to the problems associated with NDT applications, an intelligent analysis system that supports a portable testing environment, which allowed various types of inputs and provided sufficient data regarding level of damage in a tested … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,970 accessesView PDFCite
Research ArticleOpen accessIn the keywordsModified Center Interpolation Net for Classification of Composite Structures Tested Using Low Frequency Electronic TappingMahmoud Z. IskandaraniProblem statement: Most exhaustive NDT techniques require large capital equipment, are difficult to apply to complex geometric structures and, above all, are time-consuming to use and some take a considerable time to complete. As a solution to the problems associated with NDT applications, there is a need to establish an intelligent analysis system that supports a portable testing environment, which … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,108 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCementation Analysis by Eddy Current MethodM. Zergoug, H. Oubouchou, N. AmimeurIncrease the hardness, the endurance and the life time of material can be realised by surface treatments and remetallings, the electromagnetic properties of steels depend on their composition, their microstructures and constraints applied. We can use the electric and magnetic parameters to evaluate their microstructure. The object of this work is the characterization of cementation by the non-destructive methods and … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,565 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfrared Thermography for the Characterization of Painted Vaults of Historic Masonry BuildingsClaudia Casapulla, Alessandra Maione, Luca Umberto ArgientoThe infrared thermography is a type of non-destructive investigation which can find interesting application in acquiring information about the structural features of ancient masonry buildings. In this case, in fact, the needs of preservation of the historical values have to be compound with the needs of achieving a proper level of knowledge of the parameters influencing the structural behaviour in … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 20 Feb 2018 · 7,867 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Approach to Damage Detection in Composite Body Structures Using Time Compensated Hyperspectral Image Analysis TechniqueMahmoud Zaki IskandaraniA novel approach to damage detection in composite car body structures using hyperspectral image index analysis algorithm is presented and discussed. The adapted technique allows the monitoring and analysis of a components structure based on correlation between time spaced thermal images. The technique produces several organized tables resulting from image fusion and frame deviation pixel redistribution calculations, which results in … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 1 Feb 2013 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the author namesUse of Lazy Wavelet and DCT for Vibration Signal CompressionPierre ELE, Auguste Ndtoungou, Jean Pierre Ngantcha, Aimé Joseph Oyobe OkassaIn this study, we compress and decompress the vibration signals from the functioning of a ball bearing. The methodology used to compress the vibration data in this study is to reduce the size of the data by reducing the spectral redundancy of the samples. We have used the DCT, which is recognized for its representational parsimony and bleaching power. To … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 6,863 accessesView PDFCite
Technical ReportOpen accessIn the abstractAnalysis 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
