Research ArticleOpen accessIn the abstractSpeech Signal Analysis in Phase DomainHusne Ara Chowdhury, Mohammad Shahidur RahmanSpeech signal analysis based on the Phase Spectrum (PS) in the recent years becomes more popular to the researchers due to its attractive properties. Though some problem arises during its processing but appropriate modification gives the useful result. In this study, we proposed a new method of speech signal analysis based on its phase spectral representation. After analyzing the PS … …Journal of Computer Science, Vol. 16, Issue 8 · 10 Aug 2020 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensing the Hydrogeomorphology and Palaeohydrologic Features of Mars Planet with Inference from the Egyptian Desert: An Insight from Satellite ImagesMohamed YousifThe water access in any planet of the universe can be considered a crucial evidence for life existence. The study of Mars has special importance where it has a complex preserved geological record of a time period longer than on Earth. Many regions of Mars planet are subjected to observations through the obtained satellite images in comparison to similar areas … …Space Science International, Vol. 4, Issue 1 · 27 Apr 2020 · 13,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractSSR Analysis of Nuclear DNA of Annual and Perennial Sunflower Species (Helianthus L.)N.V. Markin, A.V. Usatov, A.V. Grinko et al.Genotyping of 29 species of genus Helianthus L., including 5 annual and 24 perennial species from the collection of the N. I. Vavilov All-Russian Institute of Plant Genetic Resources has occurred, for this purpose were selected 52 SSR markers, with localization on all the 17 linkage groups of the sunflower genome. All the studied sunflower samples had unique SSR loci … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 25 Apr 2020 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultipatch-GLCM for Texture Feature Extraction on Classification of the Colon Histopathology Images using Deep Neural Network with GPU AccelerationToto Haryanto, Adib Pratama, Heru Suhartanto et al.Cancer is one of the leading causes of death in the world. It is the main reason why research in this field becomes challenging. Not only for the pathologist but also from the view of a computer scientist. Hematoxylin and Eosin (H&E) images are the most common modalities used by the pathologist for cancer detection. The status of cancer with … …Journal of Computer Science, Vol. 16, Issue 3 · 5 Mar 2020 · 9,215 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroduction to Fundamental Concepts of Spectroscopy Using the Lhires III SpectrographIvan Dario Arellano Ramirez, Angelica Maria Guapacha, Jairo Alberto Aguirre GalvisThis article proposes and analyzes the use of the high-resolution Lhires III spectrograph as a pedagogical tool for teaching-learning concepts of optical spectroscopy. A methodology was developed and it was tested in a population of 20 students from different engineering programs at the Technological University of Pereira, Colombia. The methodology was implemented through a guide, which describes the 3 experiments … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 22 Dec 2017 · 8,227 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of Novel Gated Integrator for the Heavy ion Beam Monitors SystemDjamet Yimga Arnaud, Wembe Tafo Evariste, Essimbi Zobo BernardIn this study, the objective is to realize a Gated Integrator (GI) circuit for silicon strip, Si(Li), CdZnTe and CsI detectors etc. With the development of radioactive ion beam physics, heavy-charged particles like carbon ions have been applied to the treatment of deep-seated inoperable tumors in the therapy terminal of the Heavy ion Research Facility in Lanzhou (HIRFL) located at … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 27 Feb 2017 · 7,174 accessesView PDFCite
Research ArticleOpen accessIn the abstractTechnique for In-Vivo Measurements of Heart Deformation Using Digital Image CorrelationRonald B. Bucinell, Matthew T. Adams, Mcolisi Dlamini, Leo J. FleishmanMany techniques used to measure the deformation of biological tissue are inadequate for measuring deformations of hearts in vivo. Bull Frogs (Rana Catesbeiana) were double-pithed and dissected to expose the amphibian heart for the measurements conducted in this study. White titanium dioxide powder and black charcoal were applied to the surface of the heart to create an artificial surface pattern … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 14 Dec 2016 · 7,947 accessesView PDFCite
Research ArticleOpen accessIn the abstractContribution of Remote Sensing in the Estimation of the Populations Living in Areas with Risk of Gully Erosion in Kinshasa (D.R. Congo). Case of Selembao TownshipKayembe wa Kayembe Matthieu, Ngoy Ndombe Alain, Makanzu Imwangana Fils et al.This paper proposes a methodology combining very high spatial resolution satellite image, GIS and field surveys to estimate the number of people living in areas at (high) risk of landslides or gully erosion in Selembao (Kinshasa). It also gives their socio-economic characteristics. Results show that 185,000 out of the 314,699 inhabitants estimated in Selembao (58.3% of the population) live in … …Current Research in Geoscience, Vol. 6, Issue 1 · 6 Jun 2016 · 8,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Course Resolution Multiple-Receiver Approach for Reception of Slow Fading Signals in Digital Wireless Communication SystemsAshraf Mamdouh Aziz, Senior Member, IEEE et al.Multiple-receiver digital wireless communication systems employ several receivers and a digital central receiver with data fusion to reduce the effect of multipath fading problems. The multiple receiver observations are processed at individual receivers and sent to a digital central receiver. The digital central receiver fuses all the individual receiver data to form global data on which symbol was transmitted. In … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 7 Sep 2015 · 6,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractSUPER RESOLUTION FOR EGYPTSAT-1 IMAGES WITH ERRATIC SHIFTA. H. Nasr, Gh.S. El-Tawel, A. K. HelmyThe key point of the Super-Resolution (SR) process is the accurate registration of the low resolution images, i.e., accurate measuring of the fixed shift between them, to obtain high resolution image. Due to certain malfunction, some Egyptsat-1 images have inconsistent sub-pixel shift. Therefore, in this study we propose a methodology to use this kind of shift for reconstructing a SR … …Journal of Computer Science, Vol. 10, Issue 7 · 17 Jun 2014 · 6,938 accessesView PDFCite
