Research ArticleOpen accessIn the abstractMulti-Phase Support Vector Regression Soft Sensor for Online Product Quality Prediction in Glutamate Fermentation ProcessRongjian Zheng, Feng PanGlutamate fermentation is inherently nonlinear, multi-phase and an aerobic fermentation process. As long measurement delays and expensive apparatus cost, on-line measurement of the product concentration is not necessarily available. The present fermentation process monitoring and quality prediction involve manual interpretation of highly informative, however, the concentrations of substrates, biomass and products are only low frequency off-line measurements. In this paper, … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 2 · 6 Jun 2017 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining Causes of Gully Erosion and Associated Rates of Change in South-East Nigeria, using a Remote Sensing and GIS MethodologySylvanus IroThe study of gully development on a regional scale is currently threatened by the intrinsic costs associated with steady field tracking and monitoring and the lack of historic measurements to perform time series analysis. The research objective is to develop a low-cost GIS and Remote Sensing methodology for monitoring and quantifying gully erosion and development over time, identifying the impact … …American Journal of Environmental Sciences, Vol. 16, Issue 5 · 22 Oct 2020 · 7,431 accessesView PDFCite
Review ArticleOpen accessIn the abstractAdopting Intelligent Modelling to Trace Fault in Underground Optical Network: A Comprehensive SurveyOwusu Nyarko-Boateng, Adebayo F. Adekoya, Benjamin A. WeyoriAiming at building new global optical network infrastructure optimized with fault tracing capabilities, light transmission monitoring, packets re-routing and reconfigurations require an intelligent optical transmission system. An intelligent approach to solve the increasingly complex problems, to enhance fault tracing in the underground optical network infrastructure need to be adopted. For over forty decades now, Optical Time Domain Reflectometry (OTDR) technology … …Journal of Computer Science, Vol. 16, Issue 10 · 13 Oct 2020 · 6,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand-Cover Removal and Gully Development in Southeast Nigeria: A 30-Year Analysis with Pixel and OBIA Approaches in JuxtapositionSylvanus IroIn this study a study of gully erosion in southeast Nigeria is presented. The study of gully development on a regional scale is currently undermined by the inherent costs associated with consistent field monitoring and the lack of historic measurements to perform time series analysis. As a result, there are very few studies which implement long term analyses of gullies … …American Journal of Environmental Sciences, Vol. 16, Issue 2 · 9 Jun 2020 · 7,383 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsymptotic Stability of Unicycle-Like Robots: The Bessel’s ControllerAndrés G. GarcíaAsymptotic stability of unicycle-like robots proved to be involved due to Brockett's condition. By using a smooth, time-invariant controller constructed out of Bessel’s functions, in this paper unicycle-like robots are uniformly-exponentially stabilized to the origin. The pure feedback controller obtained provides closed-form trajectories with the possibility of a simple and feasible (hardware) non-linear observer construction from posture angle measurements solely. … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 17 Jan 2020 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractNeurophysiological Mechanisms of Rapidity Quality Development in Female Students Going in for Basketball and Volleyball at Sports ClubsAngelina Shakhanova, Aida Cheuzheva, Ekaterina Kalnaya, Tatiana PetrovaUsing the “NS-Pshykho Test” certified software package (Ivanovo, Russia), we studied the measurements of Simple Hand-Eye Response time (SHER), tapping test frequency, time of Reaction To Moving Object (RMO), Critical Flicker Fusion Frequency (CFFF) in female students going and not going in for sports (volleyball, basketball) at sports clubs. The basis of neuromotor state is formed by variants of classical … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 17 May 2016 · 7,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractPathologies of Acute Interstitial Pneumonia in Feedlot CattleJose A. Valles, Michael D. Apley, Chris D. Reinhardt et al.Acute Interstitial Pneumonia (AIP) is a costly issue that affects feedlot cattle. Research has yet to elucidate the etiology of AIP; therefore a case-control study was conducted to evaluate possible management and physiological factors that contribute to AIP in feedlot cattle. The experiment was conducted during the summer of 2011 in a commercial feedyard in Kansas. Animals exhibiting clinical signs … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 30 Mar 2016 · 7,896 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Cement Dust on the Physiological Activities of Arabidopsis thalianaSaeid Abu-Romman, Jarrah AlzubiAir pollution exerts detrimental effects on plant ecosystems and restricts agricultural productivity. Cement dust is considered to be one of the most harmful air pollutants of industrial origin and is a limiting factor for plant growth and productivity. This study aims to uncover the impacts of cement dust on photosynthetic pigments, protein content, hydrogen peroxide (H2O2) accumulation, lipid per oxidation … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 17 Nov 2015 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonomers Release from Dental Composites: Effect of Immersion Media and Photoactivation Light SourceRaquel A.B. da Silva, Talita P. Prates, Driely Barreiros et al.The present study aimed to evaluate qualitatively and quantitatively the products released by composites with different light sources when immersed in distilled water or artificial saliva. Thirty-six samples were obtained from the composites using a silicone matrix. Specimens were divided into 12 groups according to: Composite (Charisma®, FiltekTMSilorane or GC Kalore®), device used for the materials photoactivation (halogen light or … …Current Research in Dentistry, Vol. 5, Issue 1 · 14 Jan 2015 · 7,188 accessesView PDFCite
