Abstract Unsteady aerodynamic force refers to the that magnitude and direction of load borne by aircraft will change with time during flight. Usually, simulation unsteady is completed wind tunnel test. This paper introduces a new method based on electromagnetic field Ampere force. Compared traditional test method, greatly reduce cost make it possible repeat multiple tests. In order verify wheth...
Introduction and aim: Attention-Deficit / Hyperactivity Disorder is one of the most common psychiatric disorders in children. Finding treatments to improve these people is scientifically important. This study aimed to evaluate the effectiveness of motor games based on Montessori theory on external forces on the body in children with attention-deficit /hyperactivity disorder while walking. Meth...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
we have calculated the phonon frequencies of kc1 along symmetry directions using an approach which is a combination of the frozen phonon and force constants methods. we also calculated griineisen parameters for all modes at x and l points in the brillouin zone. finally, the slope of acoustic dispersion curves around zone center were used to calculate the three independent elastic coefficients c...
A novel nonlinear fractional order sliding mode controller is proposed to control the chaotic atomic force microscope system in presence of uncertainties and disturbances. In the design of the suggested fractional order controller, conformable fractional order derivative is applied. The stability of the scheme is proved by means of the Lyapunov theory based on conformable fractional order deriv...
