A Fuzzy Expert System Architecture for Intelligent Tutoring Systems:A Cognitive Mapping Approach

引用

Journal of Intelligent Learning Systems and Applications 2012年第1期4卷 29-40页

An Intelligent Tutoring System (ITS) is a computer based instruction tool that attempts to provide individualized instructions based on learner’s educational status. Advances in development of these systems have rose and fell since their emergence. Perhaps the main reason for this is the absence of appropriate framework for ITS development. This paper proposes a framework for designing two main parts of ITSs. Besides development framework, the second main reason for lack of significant advances in ITS development is its development cost. In general, this cost for instructional material is quite high and it becomes more in ITS development. The proposed method can significantly reduce the development cost. The cost reduction mainly is because of characteristics of applied mapping techniques. These maps are human readable and easily understandable by people who are not aware of knowledge representation techniques. The proposed framework is implemented for a graduate course at a technical university in Asia. This experiment provides an individualized instruction which is the main designing purpose of the ITSs.

Chinese Journal of Traumatology 2018年第1期21卷 54-57页

作者： Mehrdad Mahdian Mojtaba Sehat mohammad Reza fazel Hossein Akbari Habibollah Rahimi Mahdi mohammadzadeh Trauma Research Center. Kashan University of Medical Sciences Kashan Iran Department of Biostatistics and Epidemiology School of Health Kashan University of Medical Sciences Kashan Iran

Purpose： The aim of this study was to analyze the trend of road traffic fatalities in Kashan Region, lran, in a period of eight years. Methods： Through a cross-sectional study, all road traffic deaths classified under the VO1-V99 codes according to ICD-10 in Kashan region, central Iran, from March 2006 to March 2013 and population data were collected from the registration system of Kashan University of Medical Sciences. Years of lost life （YLL） and mortality rates were calculated regarding age, gender and year of the accident. Generalized linear model （GLM） with Poisson log-linear link was used to evaluate the effects of the mentioned variables on mortality rate. Results： During the period of the study （8 years）, 928 people （767 men） died due to road traffic injuries （RTIs）. The total YLL was 20,818. The mortality rate due to RTIs has been declined constantly from 43.1 in March 2006 to 21.1 per 100,000 in March 2013. The highest mortality rate was found in the age group of over 60 years old and the lowest in the age group of 0-14 years old. Both mortality rate and YLL was greater in men than in women. Poisson regression showed that age, gender and year of the accidents had a significant effect on mortality rate （p 〈 0.001 ）. Conclusion： Although there has been a constant decline of mortality rate in Kashan area within the study period, the value remains higher than the mean level of Eastern Mediterranean region and the global average, which is a notable fact for policymakers and authorities.

Purpose： Ocular trauma is the third leading cause of hospitalization in ophthalmology patients, imposing direct and indirect physical and psychological costs on society. This study aims to investigate the status of ocular trauma in hospitalized patients in the industrialized city of Kashan in 2011. Methods： This cross-sectional descriptive applied study was conducted in 2012 on patients hospitalized for ocular trauma. Data, including age, gender, occupation, education, timing of admission following accident, location of accident, type of injury, damaging instrument, and type of trauma, were collected using a questionnaire designed by a trained nurse, and analyzed using SPSS-lfi software by means of means _＋ standard deviation, frequency, and percentage for descriptive data and t-test, one-way analysis of variance, Chi-square and Fisher exact test for analysis at significance level ofp 〈 0.05. Results： In total, 82 patients were hospitalized due to ocular traumas. The majority of patients were male （65 patients, 79.3%）. Their mean age was （25.4 ± 21.4） years, with an age range of 20-40 years （30 patients, 36.6%）. Hyphema was the most common injury （26 patients, 25.5%）, home was the most frequent incident location （32 patients, 39%）, and knife or other cutting tools were mostly responsible for injuries （18 patients, 21.9%）. Patients were hospitalized for 1-6 days, and the average length of stay in hospital was 2.63 days. Frequency distribution of injuries based on whether or not ruptures differed significantly among different age groups. Conclusion： The majority of ocular trauma occurred in young males. Knife was the principle culprit for eye injuries, followed by vehicles. To reduce such incidents, it is recommended that people be trained to avoid high-risk behaviors when using knives and to better heed driving rules and regulations.

A three dimensional CFD simulation and optimization of direct DME synthesis in a fixed bed reactor

引用

Petroleum Science 2014年第2期11卷 323-330页

作者： fazel Moradi mohammad Kazemeini Moslem Fattahi Department of Chemical and Petroleum Engineering Sharif University of Technology Department of Chemical Engineering Abadan Faculty of Petroleum Engineering Petroleum University of Technology

In this study, a comprehensive three-dimensional dynamic model was developed for simulating the flow behavior and catalytic coupling reactions for direct synthesis of dimethyl ether （DME） from syngas including CO2 in a fixed bed reactor at commercial scale under both adiabatic and isothermal conditions. For this purpose, a computational fluid dynamic （CFD） simulation was carried out through which the standard κ-ε model with 10% turbulence tolerations was implemented. At first, an adiabatic fixed bed reactor was simulated and the obtained results were compared with those of an equivalent commercial slurry reactor. Then the concentration and temperature profiles along the reactor were predicted. Consequently, the optimum temperature, pressure, hydrogen to carbon monoxide ratio in the feedstock and the reactor height under different operation conditions were determined. Finally, the results obtained from this three-dimensional dynamic model under appropriate industrial boundary conditions were compared with those of others available in literature to verify the model. Next, through changing the boundary conditions, the simulation was performed for an isothermal fixed bed reactor. Furthermore, it was revealed that, under isothermal conditions, the performed equilibrium simulations were done for a single phase system. Considering the simultaneous effects of temperature and pressure, the optimum operation conditions for the isothermal and adiabatic fixed bed reactors were investigated. The results of the H2＋CO conversions indicated that, under isothermal condition, higher conversion could be achieved, in compared with that under adiabatic conditions. Then, the effects of various operating parameters, including the pressure and temperature, of the reactor on the DME production were examined. Ultimately, the CFD modeling results generated in the present work showed reasonable agreement with previously obtained data available in the literature.

·AIM:To identify various risk factors that may play a significant role in the development of congenital nasolacrimal duct obstruction(CNLDO).·METHODS:This observational case-control study included a case group of 122 children less than two years of age with CNLDO who underwent probing and irrigation treatment at the ophthalmology department of Imam Khomeini Hospital in Ahvaz,Iran,from June 2022 to June2024.A control group of 122 age-matched children without CNLDO was also included for *** was collected from the children's medical records.·RESULTS:The study found a significant correlation between the occurrence of CNLDO and several maternal factors,such as preeclampsia,the use of levothyroxine,hypothyroidism,having more than three pregnancies(gravidity>3),natural pregnancy,and gestational diabetes ***,in children,factors,such as oxygen therapy,anemia,reflux,jaundice,and a family history of CNLDO in first-degree relatives were associated with CNLDO,and maternal preeclampsia and hypothyroidism were found to significantly increase the risk of developing CNLDO in children.·CONCLUSION:Given that CNLDO affects both premature and full-term children,the present findings may potentially facilitate the early identification of children and infants at risk of nasolacrimal duct obstruction,thereby preventing the onset of chronic dacryocystitis.
