| 1 | An artificial neural network approach for prediction of long-term strength properties of steel fiber reinforced concrete containing fly ash显示文摘In this study, an artificial neural network (ANN) model for studying the strength properties of steel fiber reinforced concrete (SFRC) containing fly ash was devised. The mixtures were prepared with 0 wt%, 15 wt%, and 30 wt% of fly ash, at 0 vol.%, 0.5 vol.%, 1.0 vol.% and 1.5 vol.% of fiber, respectively. After being cured under the standard conditions for 7, 28, 90 and 365 d, the specimens of each mixture were tested to determine the corresponding compressive and flexural strengths. The pa- rameters such as the amounts of cement, fly ash replacement, sand, gravel, steel fiber, and the age of samples were selected as input variables, while the compressive and flexural strengths of the concrete were chosen as the output variables. The back propagation learning algorithm with three different variants, namely the Levenberg-Marquardt (LM), scaled conjugate gradient (SCG) and Fletcher-Powell conjugate gradient (CGF) algorithms were used in the network so that the best approach can be found. The results obtained from the model and the experiments were compared, and it was found that the suitable algorithm is the LM algorithm. Furthermore, the analysis of variance (ANOVA) method was used to determine how importantly the experimental parameters affect the strength of these mixtures. | Okan KARAHAN Harun TANYILDIZI Cengiz D.

| 4 | Analytic Hierarchy Process for Evaluating Flipped Classroom Learning显示文摘In reality,the flipped classroom has gained popularity as a modern way of structuring teaching,where lectures move from in-class procedures to digitally-based assignments,freeing up the debate,and practice exercises class time.Therefore,it is essential to implement and analyze a way of teaching that will improve student performance.The paper aims to develop a model of the method of teaching science in Iraqi schools,and to assess whether teaching flipped classroom affects the achievement,motivation,and creative thinking of students by using the methodology of Multi-Criteria Decision Making(MCDM)in the Analytic Hierarchy Process(AHP).The AHP approach includes several steps,including setting assessment criteria and their weights,and by assessing the methodology of the flipped classroom as compared to the conventional cognitive learning process.An experiment was carried out in Iraqi secondary schools to examine the attitude of the students towards the subject of Chemistry.The findings have indicated that the students and teachers favored flipped classroom learning more than conventional cognitive learning.The study took the following parameters compared to the traditional approach:teaching techniques,learning flexibility,teaching aids effectiveness,student participation and working environment.This paper indicates that the teachers in Iraqi schools will be able to improve and do more preparation to shift towards flipped learning in the classroom. | Husam Jasim Mohammed Hajem Ati Daham | 2021 | Computers, Materials & Continua2021，，3： | 2 |
