modeling is one of the most interesting areas in various fields of science. unfortunately data quality, which has an important role in the modeling, is not considered. in fact, most often processes encounter disturbances which results in the collection of abnormal data and may lead to a model different from the real behavior of the process. on the other hand, most of real industrial processes a...

background: relapse is a common problem in drug user’s rehabilitation program and reported in all over the country. an in-depth study on patients’ experiences can be used for exploring the relapse process among drug users. therefore, this study suggests a model for relapse process among iranian drug users. methods: in this qualitative study with grounded theory approach, 22 participants with ri...

mathematical modeling and simulation of microbial polyhydroxybutyrate (phb) production process is beneficial for optimization, design, and control purposes. in this study a batch model developed by mulchandani et al., [1] was used to simulate the process in matlab environment. it was revealed that the kinetic model parameters were estimated off the optimal or at a local optimal point. therefore...

abstract today, competitive strategies have got accepted as one of the most important means of manager to compete in markets. in the strategic management process, development of the strategic quantitative objectives based merely on the experts’ ideas.in this research, after reviewing the bsc,swot, judo strategy model and blue ocean strategy model, the concepts are applied to increase quality of...

the bubble effectiveness in liquid phase cylohexane non-catalytic oxidation process is discussed in this paper. then the bubble effectiveness and a new proposed kinetic model are used in the mathematical model of the industrial reactor for the cyclohexane non-catalytic oxidation process. furthermore, simulation and optimization based on this reactor model are carried out. the results of simulat...
