Research ArticleOpen accessIn the abstractUltrasonic Study and Physical Properties of Borotellurite GlassesW.M. Daud, H. Zainul, Z.A. Talib et al.A series of glasses (TeO2)x (B2O3)1-x with x = 0.6, 0.63, 0.65, 0.70, 0.73, 0.75, 0.78 and 0.80 were synthesized by rapid quenching. Longitudinal and shear ultrasonic velocity were measured at room temperature and at 5 MHz frequency. Elastic properties, Poisson’s ratio and micro hardness have been calculated from the measured density and ultrasonic velocity at room temperature. Estimated parameters … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,910 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordUse of the Nere Pod (Parkia Biglobosa) for the Improvement of Mechanical Properties of SoilsSinko Banakinao, Sonnou Tiem, Kodjo Attipou et al.Buildings made of unbaked clay have some advantage in terms of production cost. However, they have some inconveniences concerning their mechanical performance, particularly their resistance to weather. The objective of this study is to minimize these disadvantages and to maximize the benefits of such buildings to make them more viable. For this purpose, a method based on a traditional practice … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 16 Feb 2017 · 7,851 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMedical Image Compression with Lossless Region of Interest Using Adaptive Active ContourR. Loganathan, Y. S. KumaraswamyProblem statement: With increasing bandwidth, digital medical image storage and transmission is a boon to patients and health professionals alike. Medical images are available instantly and avoid the need to carry the data physically. Popular imaging techniques extensively used in medicine include X-Ray, Magnetic Resonance Imaging (MRI), Ultrasound and Computed Tomography (CT). The images produced from the above techniques can … …Journal of Computer Science, Vol. 8, Issue 5 · 1 Mar 2012 · 7,723 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComparative Study of the Effect of Lossy and Lossless Block Based Binary Plane Techniques on Medical ImagesNalla Subhash Chandra, Mahaboob Basha Shaik, A. Govardhan, M. BalrajuProblem statement: The general and medical images in specific contain different regions holding information of different significances. To elaborate medical information, the doctor prefers to focus on certain selected region (s) of interest. So for medical images the diagnostically important regions must be preserved at high quality, whereas the rest of the image is required only in a contextual sense. … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,380 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordFractal Images Compressing by Estimating the Closest Neighborhood with Using of Schema TheoryMahdi Jampour, Mahdi Yaghoobi, Maryam AshourzadehProblem statement: One of the methods used for compressing images and especially natural images is by benefiting from fractal features of images. Natural images have properties like Self-Similarity that can be used in image compressing. The basic approach in compressing methods is based on the fractal features and searching the best replacement block for the original image. Approach: In this … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,899 accessesView PDF Cite
