Research ArticleOpen accessPhrase in the titleFractal Dimension for Lung Sound Classification in Multiscale SchemeAchmad Rizal, Risanuri Hidayat, Hanung Adi NugrohoLung sound is a biological signal with the information of respiratory system health. Health lung sound can be differentiated from other pathological sounds by auscultation. This difference can be objectively analyzed by a number of digital signal processing techniques. One method in analyzing the lung sound is signal complexity analysis using fractal dimension. To improve the accuracy of lung sound … …Journal of Computer Science, Vol. 14, Issue 8 · 24 Aug 2018 · 9,279 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleFractal Dimension for the Characterization of Asphalt Mixture PropertiesGiovanni LeonardiIn the design of asphalt mixtures for paved roads, the shape of solid elements has a great importance. In asphalt concrete, the shape of aggregate particles influences the resistance, durability, stiffness, fatigue response and the required binder content of the mixture. Fractal geometry is more suitable to describe the irregularity of the shape of aggregate particles. This paper describes the … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 13 Jul 2016 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTrends and Multifractal Analyses of Precipitation Data from Shandong Peninsula, ChinaMeng Gao, Xiyong HouProblem statement: Water shortage is a very serious problem in Shandong Peninsula, which is one of the most rapidly developed zone in China. As the major source of water supply is in this area, precipitation is crucial to sustainable development in Shandong Peninsula. The purpose of the present study is to investigate the trend and characteristics of precipitation during the … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 23 May 2012 · 7,160 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKoch Curves: Rewriting System, Geometry and ApplicationMamta Rani, Riaz Ul Haq, Norrozila SulaimanProblem statement: Recently, new Koch curves have been generated by dividing the initiator into three unequal parts. There is no formal rewriting system to generate such kind of curves. Approach: It is required to measure the new changed geometrical properties. Generalized rewriting systems for the new Koch curves have been developed. Results: New formulas have been given to measure their … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,065 accessesView PDFCite
Research ArticleOpen accessIn the abstractProcess Physics: Emergent Unified Dynamical 3-Space, Quantum and Gravity: A ReviewReginald Thomas CahillExperiments have repeatedly revealed the existence of a dynamical structured fractal 3-space, with a speed relative to the Earth of some 500 km sec-1 from a southerly direction. Experiments have ranged from optical light speed anisotropy interferometers to zener diode quantum detectors. This dynamical space has been missing from theories from the beginning of physics. This dynamical space generates a … …Physics International, Vol. 6, Issue 2 · 4 Aug 2015 · 8,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractContent Based Image Retrieval of Ultrasound Liver Diseases Based on Hybrid ApproachR. Suganya, S. RajaramProblem statement: In the past few years, immense improvement was obtained in the field of Content-Based Image Retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted from … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 24 Mar 2012 · 7,643 accessesView PDFCite
