Research ArticleOpen accessEvery word in the titlePerformance Comparison of Passive Fault Tolerant Control Strategy with PI and Fuzzy Control of Single-Tank Level Process with Sensor and System FaultHimanshukumar R. Patel, Vipul A. ShahFault-Tolerant Control (FTC) strategy has gain maximum attention in recent years in chemical industries due to economical and safety hazards perspective. Targeting at the decreasing control performance of the single-tank level control process under the constraint of system and sensor faults, this article presents model-based Passive Fault-Tolerant Control (PFTC) strategy which are based on conventional and artificial intelligence control. The … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 24 Jun 2019 · 7,598 accessesView PDFCite
InvestigationOpen accessEvery word in the titleEvaluation of Black Currant Cultivars Resistance to Aphis grossulariae Kalt. and Effectiveness of Water Extracts of Artemisia Absinthium L. and Tanacetum Vulgare L. Against this PestNatalya Gennadievna Andrianova, Tatyana Vladimirovna Likhacheva, Tatyana Olegovna SirotinaThis study consisted in revealing the possibility of using two ecologically safe methods to control gooseberry aphid (Aphis grossulariae Kalt.) in black currant cultivars: selection aphid resistant cultivars and the use of plant water extracts of wormwood (Artemisia absinthium L.) and tansy (Tanacetum vulgare L.) in the arid zone of Central Kazakhstan for protection against aphid. The study of the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 1 · 26 Mar 2018 · 7,391 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Comparison of Thermal Stratification due Natural Convection in Densified LOX, LN2 TanksSeyed Ali Jazayeri, Ehsan Molla Hasanzadeh KhoeiThe growth of natural circulation and thermal stratification inside LOX, LN2 storage tanks due to heat transfer from surroundings is investigated using a non-equilibrium, two-domain, mathematical model. The two-dimensional model is considered for the liquid domain in two cases and a lumped, thermodynamic model is utilized for vapor domain. The vapor is assumed to behave like an ideal gas. The … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,967 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of the Detoxification on the Shrinkage Temperature and pH of Chromium Leather Waste, Another Promising Way for the Tannery PollutionA. Malek, M. HachemiThe leather tannery industry produces a significant amount of solid chromium waste. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. This research describes the possibility of decrease of the shrinkage temperature and to increase the pH value of leather waste by detoxification treatment with use of tartrate … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,114 accessesView PDFCite
