In this study, an integrated electrospray pyrolysis process was designed to continuously produce a representative nano-catalyst TiO2. A numerical model also developed simulate the flow behaviors and droplet transport inside reactor. The electric field particle tracking were coupled describe process. effects of key parameters, including electrode configurations, applied voltage, charge density, ...

the classical control charts by using precise and specified data divide the production process into two groups: in-control or out of control, while the fuzzy sets with the definition continuous and cohesive membership functions and also using ambiguous and vague fuzzy numbers (triangular and trapezoid), it introduces different levels of decisions for the decision makers. in this paper, using th...

this paper is devoted to the study of determining optimal process mean in system production with the two markets for the sale of goods. in this paper, we developed an absorbing markov chain model in production systems where all items are inspected %100 for conformance with their specification limits. when the value of the quality characteristic of an item falls below a lower limit, the item is ...

The potential bioconversion of synthesis gas (syngas) to fuels and chemicals by microbial cell has attracted considerable attention in past decade. The feasibility of enhancing syngas bioconversion to ethanol and acetate using Clostridium ljungdahlii in a continuous tank bioreactor (CSTBR), kinetics and mass transfer coefficient of carbon monoxide (CO) utilization were evaluated. Two different ...

Quantitative methods seek to explore how a system evolves in the dimensions of space and time. The usual notion of space is a discrete one such as the reachable states of a high-level model, but others are possible, such as fluid models. The usual notion of time is a continuous one such as the average duration of activities, as used in stochastic processes governed by the exponential distributi...
