objectives: in present study, we studied the effect of teaching three painting methods (free method, subject selection method and complementary method) on creativity of children with learning disabilities. first, among all disabled students, who refer to bizhani center for learning disabilities in arak city, 60 subjects were randomly selected as statistical sample. thus, the 45 children, divide...
there are miscellaneous quality characteristics in healthcare which are interested to be monitored. however, monitoring each characteristic needs a special statistical method. there are some characteristics with very small incidence rates that it’s usually considered not to be necessary to monitoring them, since their incidence rates are so small that p and np charts are not able to monitor the...
the purpose of this study is to implement a new modification of the variational iteration method (h-s-vim), which is a combination of spectral method and variational iteration method for heat transfer problems with high nonlinearity order. the merit of this method is that it does not require the solution of any linear or nonlinear system of equations unlike spectral method. furthermore the prop...
the current paper focuses on some analytical techniques to solve the non-linear duffing oscillator with large nonlinearity. four different methods have been applied for solution of the equation of motion; the variational iteration method, he’s parameter expanding method, parameterized perturbation method, and the homotopy perturbation method. the results reveal that approximation obtained by th...
reduced differental transform method (rdtm), which isone of the useful and effective numerical method, is applied to solve nonlinear time-dependent foam drainage equation (fde) with different initial conditions. we compare our method with the famous adomian decomposition and laplace decomposition methods. the obtained resultsdemonstrated that rdtm is a powerful tool for solving nonlinear par...
in this paper, nonlinear klein-gordon equation with quadratic term is solved by means of an analytic technique, namely the homotopy analysis method (ham).comparisons are made between the adomian decomposition method (adm), the exact solution and homotopy analysis method. the results reveal that the proposed method is very effective and simple.
By interrupting the traditional approach to the distinctiveness of the order of knowledge and the order of nature (which was the procedure of many philosophers like Aristotle, and his scholastic disciples, more especially of Thomas Aquinas and even Descartes and Cartesian), and acquiring a unified science, Spinoza changes the customary order of philosophizing and begins his famous book, Ethics,...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
در میان پدیده های فیزیکی موجود در انتقال حرارت، کوره های صنعتی و محفظه های احتراق با هندسه های گوناگون از اهمیت ویژه ای برخوردار می باشند. انتقال حرارت تشعشعی در این گونه از مسائل سهم قابل توجهی از میزان انتقال حرارت کلی را به خود اختصاص می دهد. یافتن جواب تحلیلی دقیق برای معادله انتگرودیفرانسیلی انتقال حرارت تشعشعی بسیار مشکل می باشد. برای مدل سازی فرآیند انتقال حرارت تشعشعی در یک محیط مشارکتی...
