EditorialOpen accessIn the abstractData Mining in Time Series: Current Study and Future TrendTan Yan, Liudmila Ulanova, Ye Ouyang, Fengyuan XuTime series represent sequences of data points where usually their order is defined by the time when they were recorded. Thus, virtually any sequential recordings can be stored as time series: Stock prices, weather conditions, physical system parameters change, product quality monitoring, etc. This leads to ubiquity of time series in all scientific and practical fields (Esling and Agon, 2012); … …Journal of Computer Science, Vol. 10, Issue 12 · 26 Jan 2015 · 8,756 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
Review ArticleOpen accessIn the abstractAbout Boeing X-32Relly Victoria Virgil PetrescuThe Boeing X-32 is a demonstration jet designed for the Joint Strike Fighter contest. He lost the Lockheed Martin X-35 demonstrator, which was further developed in the Lockheed Martin F-35 Lightning II. Boeing's competitive advantage has been to provide considerably lower costs of production and lifecycle by minimizing variations between different versions of the JSF. Therefore, the X-32 was designed … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 1 Apr 2019 · 9,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Impact Assessment of Quarrying Plants: An IRF Kriging Solution to Noise and Airborne Dust MonitoringDario Lippiello, Guido Alfaro Degan, Mario PinzariA geostatistical approach is tested for the assessment of the environmental impact generated by industrial plants on the surrounding areas. To this end, a case study of a tuff quarry in the Italian region of Lazio is presented. The method utilised is Intrinsic Kriging with external drift which allows spatial maps of different hazardous agents like noise and airborne dust … …American Journal of Environmental Sciences, Vol. 15, Issue 1 · 9 Feb 2019 · 7,885 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Detection of Follicle Stimulating Hormone Receptor Polymorphisms and Luteinizing Hormone Gene Variations in Primary and Secondary Iraqi Infertile WomenNoor Basim Naser, Dr. Ezeddin Atia Albayyar, Dr. Susan Abed ZaidanThe current study aimed to determine the role of hormonal disturbances in infertility, moreover assessing variations at the molecular level that could affect this disease. The study examined 90 blood samples, 30 patients with primary infertility, 30 patients with secondary infertility and 30 healthy women as control. FSH and LH were measured using Electrochemiluminescence assay. DNA was isolated for molecular … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 15 Nov 2018 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Dynamic Threshold Method for Skin Colour Detection Using Multi-Colour SpaceMohd Zamri Osman, Mohd Aizaini Maarof, Mohd Foad RohaniThis paper presents a skin colour detection based on an improved dynamic threshold method to reduce false skin detection. Current fixed threshold skin detection fails in certain situations such as misclassification between non skin-like with similar skin-like colour. Any true skin may falsely be detected as non-skin. Research work introduces high-level skin detection strategy based on online sampling where offline … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 19 Dec 2015 · 7,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation into the Use of Electrochemical Extraction to Draw Gold from Refractory OresBagdaulet Kenzhalyevich Kenzhaliyev, Zamzagul Duisenovna Dosymbaeva, Renata Ramilevna Iskhakova, Essen Nurgalievich SuleimenovThis paper studies the possibility of extracting gold by electrochemical leaching through the use of a sodium thiosulfate solution. In this regard, the requirements for environmentally sound technologies play a huge and vital role. Low extraction ratios and metal losses increase the cost of this process significantly and therefore it is necessary to reduce or prevent these disadvantages. Dissolution of … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 17 Nov 2015 · 6,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractFUSION OF COLOR AND MODIFIED WEBER’S LAW DESCRIPTOR BASED HUMAN SKIN DETECTIONC. Prema, D. ManimegalaiSkin detection in images or videos plays a vital role in a wide range of image processing applications like face detection, face tracking, gesture analysis, human-computer interaction etc. Due to its high processing speed and invariant against rotation, it has received significant interest in pattern recognition and computer vision. The robustness of skin detection using color information depends on real … …Journal of Computer Science, Vol. 10, Issue 9 · 19 Apr 2014 · 6,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractMOLECULAR CHARACTERIZATION OF SARCOCYTIS FUSIFORMIS AND SARCOCYSTIS BUFFALONIS INFECTING WATER BUFFALOES (BUBALUS BUBALIS) FROM EGYPTMahmoud El-Seify, Ahmed El-Morsey, Mosaad Hilali et al.Parasites of the genus Sarcocystis have the ability to infect wide range of animals, birds and reptiles. Water buffaloes are intermediate hosts for four Sarcocystis species; S. fusiformis, S. buffalonis, S. levinei and S. dubeyi. There was no previous molecular identification of Sarcocystis spp. parasitizing water buffaloes from Egypt. The current study was established to screen infection rates and apply … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 2 · 16 Apr 2014 · 7,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPLEMENTATION OF SPACE VECTOR PULSE WIDTH MODULATION TECHNIQUE WITH GENETIC ALGORITHM TO OPTIMIZE UNIFIED POWER QUALITY CONDITIONERM. Shankar, S. Monisha, H. Shesna et al.This study proposes a novel control design of Unified Power Quality Conditioner (UPQC). This design is enabled by a control framework that employs Genetic Algorithm which determines optimum points and angle for filtering and Space Vector Pulse Width Modulation Technique (SVPWM) to offer significant flexibility to optimize waveform. In addition the same framework integrates the major functions of the UPQC … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 14 Dec 2013 · 6,711 accessesView PDFCite
