Research ArticleOpen accessIn the abstractA Complex Multi-State System with Vacations in the RepairJuan Eloy Ruiz-CastroA complex multi-state system subject to wear failure and given preventive maintenance is considered. Various internal levels of degradation are assumed. The repair facility is composed of a repairperson, who may take one or more vacations during the period considered. A policy is established for the repairperson’s vacation time. Two types of task may be performed by the repairperson: corrective … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 5 Sep 2019 · 7,293 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamics of Buses - Part IIIRelly Victoria Virgil Petrescu, Raffaella Aversa, Gheorghe Frăţilă et al.Dynamics, or dynamic processes, is the part of mechanics dealing with the study of processes trying to describe as real as possible the movement of a body, element, mechanism, car, etc., also taking into account the action of the forces on the respective system with their influence on the actual movement of system. The present paper aims to present the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 20 Apr 2018 · 8,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Grain Products in TurkeyÖzlem Akay, Gökmen Bozkurt, Güzin YükselMarketing of agricultural products starts with the planning of production on the farm and ends with the sale of food or other goods to manufacturers or consumers. Overall, marketing is a main part of successful agriculture but its significance is usually underestimated, particularly in developing countries. In Turkey, annual variations in grain production are reasonable and result primarily from changes … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 10 Jul 2017 · 7,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Absorbing Agent on Moisture Reserves of Winter Wheat in the Conditions of Semiprovided Dry Farming Land of the South-East of KazakhstanLaila Klimovna Tabynbayeva, Serik Barmenbekovich Kenenbayev, Meiramgul Shagievna Suleimenova et al.In the conditions of dry-land farming, the leading factor of productivity, which is minimal, is moisture. Soil moisture directly influences the growth of plants by means of aeration, transfer of nutrient substances, absorption and transformation. The main crop acreage of the spike cereals in the south-east of Kazakhstan is located in dry farming lands that are characterized as dry and … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 27 May 2017 · 7,407 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing the Empirical and the Theoretical Probability Density of Return in which Variance Obeying Ornstein-Uhlenbeck Process at Indonesian Stock Exchange IDXDwi Satya Palupi, Eduardus Tandelilin, Arief Hermanto, Muhammad Farchani RosyidThe distribution of the probability density of a return index with stochastic volatility has been calculated. Here the stock index is assumed to follow geometric Brownian motion, while the variance is assumed to obey Ornstein-Uhlenbeck process as in Heston model. The distribution of the probability density of the return which is obtained by solving the Fokker-Planck equation of two dimensional … …American Journal of Applied Sciences, Vol. 14, Issue 9 · 17 May 2017 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Process Conditions for the Production of Holocellulase by a Bacillus Species Isolated from Nahoon Beach SedimentsEvelyn N. Fatokun, Uchechukwu U. Nwodo, Ademola O. Olaniran, Anthony I. OkohProduction of holocellulase by a newly isolated marine Bacillus species via submerged fermentation technique at varying cultivation conditions was investigated. Enzyme production was optimized by altering one variable per time. Moreover effect of lignocellulosic saccharides in inducing cellulase and xylanase production was also investigated. The 16S ribosomal Deoxyribonucleic Acid (16S rDNA) gene sequence analysis exhibited 98% sequence similarity of the … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 2 · 8 Apr 2017 · 8,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime Dimension Parameters of the Dual-Porosity Reservoir Determination using Periodic Hydraulic Pulse TestingMarat Ovchinnikov, Kushtanova Galiya GatinishnaThe process of periodic hydraulic pulses propagation in porous fractured media of dual-porosity near a vertical well is considered. Using the calculation data as the base, it is shown that the effect of the time dimension constant on the form of the filtration wave curves is essential. The conclusions on possibility of hydrodynamic model types verification which adequately describe the … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 9 Sep 2016 · 6,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Dynamic Thermal Behavior of Building Envelope in Summer Conditions By Means of in-Field Continuous MonitoringAnna Laura Pisello, Gloria Pignatta, Cristina Piselli et al.The effect of dynamic properties of building opaque envelope in summer conditions is investigated by means of an extensive continuous monitoring of a dedicated experimental field. Two test-buildings, a weather station and two microclimate stations positioned in each test-building represent the experimental field. The prototype buildings have been specifically designed to present the same stationary envelope properties, but different construction … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 25 Apr 2016 · 8,562 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Shocks in Vibrationally Nonequilibrium Diatomic Gases at Various Distances from Critical Cross-Section of NozzleRydalevskaya Maria Alexandrovna, Voroshilova Yulia Nikolaevna, Uskov Vladimir NikolaevichThe high-temperature diatomic gas flows are considered in expanding nozzles under the conditions of a disturbance of the equilibrium distribution over vibrational levels of the molecules. The investigation of such flows is bound up with the problem of the inversion of the vibrational populations in the active mediums of molecular lasers. Under diverse values of the pressure overfall on coming … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 6,655 accessesView PDFCite
Research ArticleOpen accessIn the abstractSIMULATION OF THE PROCESS OF FLOW SEPARATION AT THE ENTRANCE OF SQUARE ASPIRATING PORTOlga A. Averkova, Ilya V. Kryukov, Kirill V. Plotnikov et al.We consider the flow at the inlet to the suction square hole with sharp edges, which is located in an infinite space. The purpose of this study is to construct a mathematical model of flow separation at the entrance to square suction canal with sharp edges, located in infinite space, by using square vortex frameworks. As a part of ideology … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,685 accessesView PDFCite
