Research ArticleOpen accessIn the keywordsTHE PROPERTIES OF NUCLEAR MATTERKhaled Hassaneen, Hesham MansourThe microscopic and bulk properties of nuclear matter at zero and finite temperatures are studied in the frame of the Brueckner theory. The results for the symmetry energy are also obtained using different potentials. The calculations are based on realistic nucleon-nucleon interactions which reproduce the nucleon-nucleon phase shifts. These microscopic approaches are supplemented by a density-dependent contact interaction to achieve … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMolecular Dynamics Investigation of Cutting Force in Nanometric Cutting of Monocrystalline SiliconY.H. Chen, F.Z. Fang, X.D. Zhang, X.T. HuProblem statement: Ultra-precision machining of monocrystalline silicon has become tremendously important in microelectronic, micromechanical and optical element manufacturing and the mechanism of nanometric cutting monocrystalline silicon has been a focused research topic. Molecular Dynamics (MD) simulation is developed as an effective way for studying the material removal process at nanometric scale. Approach: Molecular Dynamics (MD) simulation of nanometric cutting is … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 8,408 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegrability and Prolongation Structure of a Generalized Korteweg-de Vries EquationPaul BrackenA closed differential ideal is constructed for a generalized Korteweg-de Vries equation. The ideal can be used to establish integrability for the equation. Some prolongation structures are determined for the equation and some larger prolongation algebras for given instances of the equation are found. The significance of this is that Backlund transformations can be developed based on them. It is … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,414 accessesView PDFCite
Review ArticleOpen accessIn the abstractUnveiling Skin Cancer: A Review of Deep Learning Techniques for DetectionGoutham Lal Shanmughamadom Harilal, Tamilselvi PanneerselvamEarly identification is essential for successful treatment and better patient outcomes since skin cancer is caused by damage to DNA in skin cells, which can result in genetic abnormalities and the possibility of metastasis. The present systematic review scrutinizes the efficacy and obstacles of early detection techniques, which differentiate between benign and malignant lesions by examining lesion attributes such as … …Journal of Computer Science, Vol. 21, Issue 9 · 23 Oct 2025 · 2,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractFace Verification for Person Re-Identification from Surveillance Camera and Drone-based VideosVimala Mathew, K. Ramesh, Tom Toby, Anu Mary ChackoPerson re-identification in surveillance camera videos is attracting widespread interest due to its increasing number of applications. It is being applied in the field of security, healthcare, product manufacturing, product sales and more. Though there are a variety of methods to do person re-identification, face verification-based methods are very much effective. In this study, a deep learning framework to perform … …Journal of Computer Science, Vol. 17, Issue 7 · 28 Jul 2021 · 7,322 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware and Software Components of an Oysters' Gape Measurement SystemAmin Ali, Kamal Ali, Aaugustine Ukpebor et al.In this work, the hardware and software used in developing a bivalve gape measurement system is explored. This system employs the Hall-effect phenomenon to accurately measure and report the gape of a bivalve. The system uses a Hall Effect sensor (Symmetry Electronics’ H2425) and a small magnet in which both are glued to the exterior of the shells of a … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 7 Sep 2019 · 8,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy-Efficient Ant Colony-Based k-Hop Clustering and Transmission Range Assignment Protocol for Connectivity Construction in Dense Wireless Sensor NetworksGokou Hervé Fabrice Diédié, Boko Aka, Michel BabriConnectivity construction is the main phase of a communication-oriented topology control process. It consists of improving the current network physical topology while preserving important properties such as connectivity and symmetry. In this paper, we address the problem of combining two of the techniques commonly used for this purpose in networks composed of a large number of energy constrained wireless sensor-nodes … …Journal of Computer Science, Vol. 14, Issue 3 · 19 Mar 2018 · 7,796 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Clean-Green Synthesis of Platinum Nanoparticles Utilizing a Pernicious Weed Lantana (Lantana Camara)Musthafa O. Mavukkandy, Sudip Chakraborty, Tasneem Abbasi, Shahid A. AbbasiA rapid, reproducible single step method is proposed for synthesizing platinum nanoparticles using an invasive weed lantana (Lantana camara, L). The method involves mixing of platinum (VI) solution, lantana leaf extract and ascorbic acid in appropriate concentrations and keeping the mixture at 95°C for 8 min. The collective action of ascorbic acid and leaf extract reduced the chloroplatinic acid to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 23 Feb 2016 · 10,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Universe in the SU(3)L⊗U—(1)X Electroweak ModelsHoang Ngoc LongWe present status of the 3-3-1 models and their implications to cosmological evolution such as inflation, phase transitions and sphalerons. The models can deal not only with the issues such as neutrino physics, dark matter, etc, but they are also able to provide quite good agreement with the Standard Cosmology: The inflation happens at the GUT scale, while phase transition … …Physics International, Vol. 7, Issue 1 · 13 Nov 2015 · 7,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Brief Review on WIMPs in 331 Electroweak Gauge ModelsP.S. Rodrigues da SilvaIn this study we review the cold dark matter problem in the context of a class of models which are a simple extension of the electroweak standard model, where the gauge symmetry is dictated by the group structure, SU(3)c⊗SU(3)L⊗U(1)X. This model, in different versions, has been able to address many interesting facts not explained by the standard model. It would … …Physics International, Vol. 7, Issue 1 · 27 Oct 2015 · 13,044 accessesView PDFCite
