Research ArticleOpen accessEvery word in the titleModified 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 · 7,110 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQuantum Hadamard Gate Implementation Using Planar Lightwave Circuit and Photonic Crystal StructuresShamsolah Salemian, Shahram MohammadnejadAn all optical method has been proposed for quantum Hadamard gate implementation. This quantum gate was realized by using Y-junction beam splitter. Normal modes in waveguides have been used as quantum bit. This all optical gate can be used in quantum computation and communication. The proposed Hadamard gate has potential of being more compact and easily realized compared to other … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,928 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTrace Metals Co-Toxicity in Hard Body Structures of Liza klunzingeri (Mugilidae: Perciformes) Mullet FishA.H. Bu-Olayan, B.V. Thomas, S.M.H. Al-HusainiThe possibility of inorganic pollutants causing stress to the marine ecosystem instigated us to conduct eco-toxicological tests on the predominant trace metals (Cu, Zn, Pb and V) in commercial important fish. Among the four metals, V had the lowest observed effect concentration (LOEC: LC15) at 6.3 µg L-1. Toxicity tests (96 h) using Multi factor Probit analysis revealed V (6.3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,515 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMINLP Optimization of Mechanical StructuresS. Šilih, T. Žula, Z. Kravanja, S. KravanjaWe presented optimization of mechanical structures, performed by the Mixed-Integer Nonlinear Programming (MINLP) optimization approach. The MINLP is a combined continuous/discrete optimization technique, where a structural topology and standard/discrete sizes are optimized simultaneously with the continuous variables. Ddiscrete binary 0-1 variables were used to express the discrete decisions. For solution of this non-linear, continuous/discrete and non-convex MINLP class of the … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,129 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMathematical Modeling for Shakedown Analysis of Offshore StructuresMohammad Javad Fadaee, Hamed Saffari, Ramin TabatabaeiThe shakedown analysis process of an offshore structure having elastic-plastic material presented. The finite element model of the structure has been developed first, and then a simple method has been applied for shakedown analysis using matrix tool. Simplifying the relationships together with applying the theory concepts of shakedown analysis is one of the characteristics of the presented method for practical … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,068 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBlockchain-NFV for Smart Digital and Secure Physical Structures in E-Government, Healthcare, and Network SystemsHayder Abdulsattar Nahi, Ebtehal Akeel Hamed, Rusul A. Salman, Akmam Majed MosaThis paper proposed a combined model that melds Blockchain technology with Network Function Virtualization (NFV) to promote many areas, such as smart, secure, and scalable physical and digital infrastructures in E-Government, Healthcare, and Network Systems. The model treats the principal objections in conventional systems, including centralization, slowed service deployment, and restricted safety. By employing decentralized Digital Identity Decentralized identifiers (DIDs), … …Journal of Computer Science, Vol. 22, Issue 4 · 21 Apr 2026 · 1,328 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleNanomodified Adhesive Composition for Aeronautical Structures Based on Polymer Composite MaterialsVladimir Dmitrievich Vermel, Sergei Anatol’evich Titov, Yuriy Vital’evich Kornev et al.Computer simulation of the properties of Nanomodified Adhesive Compositions (NMC) based on ED-20 epoxide resin doped with carbon nanomaterials was carried out. It is shown that open carbon nanotubes are an efficient additive to increase mechanical shearing properties of adhesive compositions based on epoxide matrix. Using the nanoindentation method it was found that introduction of carbon nanotubes into adhesive compositions … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 14 Mar 2016 · 7,297 accessesView PDFCite
