12 چکیده تفاوت های فردی، به عنوان خصوصیات روانشناختی غالب، باید در سطوح مختلف تدریس و یادگیری زبان کاملاً مورد ملاحظه قرار گیرند. از میان تاثیرگذارترین سازه های روانشناختی که منجر به تفاوت های فردی می شوند، می توان ازهوش چندگانه و منبع کنترل نام برد. هوش چندگانه با جنبه های متفاوتی از هوش سر و کار دارد که ممکن است هر شخص از آن برخوردار باشد. منبع کنترل، به عنوان مفهوم روانشناختی دیگر، به استن...
The controller of the hybrid electric vehicle determines the combustion engine start-stop time, the operation points, and regenerative brake energy. The Controlling approach of hybrid electric vehicles controls the amount of needed fuel in every driving situation. In the present study, the thermostat strategy is implemented along with fuzzy logic control and compared to the classic thermostat s...
Ahatract-We investigate the existence and uniqueness of robust time-optimal control solutions of flexible structures for rest-torest motion. We show that several robust time-optimal control designs for flexible systems are equivalent to traditional nonrobust time-optimal controls for difirent systems. This equivalence implies that the robust time-optimal controllers must then have all the prope...
Boolean networks (BNs) are discrete-time dynamical systems with Boolean state-variables. BNs are recently attracting considerable interest as computational models for biological systems and, in particular, as models of gene regulating networks. Boolean control networks (BCNs) are Boolean networks with Boolean inputs. We consider the problem of steering a BCN from a given state to a desired stat...
The Acrobot, a two-link arm that is unactuated at the first joint, is challenging to control because it is an under actuated, nonlinear, continuous system. We describe a direct search algorithm for finding swingup trajectories for the Acrobot. The algorithm uses a Iookahead search that maximizes the Acrobot’s totaf energy in an N-step window. Because the controls are extremal and the number of ...
Fundamental limitations in decentralized control of systems with multivariable zeros are considered. It is shown that arbitrary bandwidth can be obtained with a stable block-diagonal controller, if certain subsystems of the open-loop system fail to have zeros in the right half-plane and a high-frequency condition holds. Implications on control structure design and sequential loop-closuring meth...
This paper introduces a method to minimize norms on nonlinear trajectory sensitivities during open-loop trajectory optimization. Specifically, we derive new parametric sensitivity terms that measure the variation in nonlinear (continuous-time) trajectories due to variations in model parameters, and hybrid sensitivities, which account for variations in trajectory caused by sudden transitions fro...
the present study aimed at investigating the relationship between iranian efl teachers’ classroom management orientations and their teaching styles. additionally, the difference between male and female teachers’ teaching styles and classroom management orientations and their relationship with experience and age were explored. three hundred efl teachers filled in attitudes and beliefs on classro...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
