Research ArticleOpen accessIn the keywordsA New Approach for 3D Range Image Segmentation using Gradient MethodDina A. Hafiz, Walaa M. Sheta, Sahar Bayoumi, Bayumy A.B. YoussefProblem statement: Segmentation of 3D range images is widely used in computer vision as an essential pre-processing step before the methods of high-level vision can be applied. Segmentation aims to study and recognize the features of range image such as 3D edges, connected surfaces and smooth regions. Approach: This study presents new improvements in segmentation of terrestrial 3D range images … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 19,597 accessesView PDFCite

Review ArticleOpen accessIn the keywordsOn Mars there was WaterFlorian Ion Tiberiu PetrescuScientists overseeing Curiosity's mission on Mars confirmed that the shape and size of the pebbles on the dry tracks indicate that they were transported and eroded by the waters. According to them, the rover found the roots of rocks equivalent to the flowing waters on Earth. The planet Mars, the closest to Terra, had life conditions similar to our blue … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 May 2018 · 8,640 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSPECTRAL DOMAIN FEATURES FOR OVARIAN CANCER DATA ANALYSISAhmed Farag Seddik, Riham Amin Hassan, Mahmoud A. FakhreldeinThe early detection of cancer is crucial for successful treatment. Medical researchers have investigated a number of early-diagnosis techniques. Recently, they have discovered that some cancers affect the concentration of certain molecules in the blood, which allows early diagnosis by analyzing the blood mass spectrum. Researchers have developed several techniques for the analysis of the mass-spectrum curve analysis and used … …Journal of Computer Science, Vol. 9, Issue 8 · 9 Jul 2013 · 6,920 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInvestigating the Effect of Powder Type on Improving the Flow in PipelinesHayder A. Abdul Bari, Rosli Bin Mohd Yunus, Tania Suhail HadiProblem statement: In the present investigation, three types of powders are chosen to be investigated as drag reducing agent in aqueous media. The effect of powder type effect will be highlighted in the present study. Approach: Three types of powders were select to be investigating in the present study, which are the sand, aluminum and the coal powders. The reason … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 7,398 accessesView PDFCite

Research ArticleOpen accessIn the abstractAccumulation and Effect of Manganese on Chloroplasts and Antioxidant Responses in Arabidopsis ThalianaJun Xing, Xue Yang, Cailing YuanIn this study, 5-day-old seedlings of Arabidopsis thaliana were exposed to 0, 0.5, and 1.0 mmol/L MnCl₂ for 6 days by using three independent biological replicates. The results indicated that Mn content in roots exhibited a dose-dependent increase with rising external Mn supply. The elevated Mn levels led to significant reductions in the nutrient content of K, Ca, Na, and … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 18 Jul 2026 · 836 accessesView PDFCite
Research ArticleOpen accessIn the abstractInputs of Numerical Simulation into the Development of Shock Adhesion Tests on Advanced MaterialsMichel ArrigoniAdvanced materials- such as assemblies, composites and materials obtained by additive methods - have met a great success in the industry of advanced technologies. They allow combining a variety of different materials and following sophisticated geometries. However, their mechanical behavior, bulk as well as in assembly, remains to be better understood to assess their reliability. For this reason, laser induced … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 10 Jan 2020 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractShift of Zeeman Components of Ionic Spectral Lines Caused by the Angular Doppler EffectEugene OksThe angular Doppler effect was introduced by Garetz. While the usual Doppler effect is caused by the translational motion of the emitter, the angular Doppler effect is caused by the rotational motion of the emitter. It results into the frequency shift of a circularly-polarized light. In the present paper we analyze the angular Doppler effect caused by the rotational motion … …Physics International, Vol. 15, Issue 1 · 16 Jun 2025 · 6,460 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvantage of Classical Approximate Analytical Methods for Studying Rydberg States Over the Quantum CounterpartsEugene OksIn studies of atomic and molecular systems, approximate analytical methods play a significant role. This is because they can be used for benchmarking the results of numerical methods. Besides they offer a physical insight into the phenomena under consideration an insight impossible to achieve by numerical methods. Many approximate analytical methods were developed in such a way that each method … …Physics International, Vol. 14, Issue 1 · 2 Jul 2024 · 8,014 accessesView PDFCite
