(Lowry et al., 1955). The standard procedure for estimation of level of lipid peroxide in organism tissue by their reaction with thiobarbituric acid developed by Ohkawa et al., 1979 was used. To estimate lipid peroxidation, 1 g of tissues was homogenized in 9 ml of ice cold 0.25 M sucrose. 0.2 ml of animal tissue homog...

After cooling, green color was developed and the absorbance was measured at 583 nm and blank also maintained. The CAT activity was expressed as mM of H 2 O 2 consumed/min/mg of protein. Determi...

NEW HEURISTIC ALGORITHMS FOR ROLLING AIR FRAME AERODYNAMIC PARAMETERS ESTIMATION In this research, based on heuristic optimization algorithms, three new strategies are developed for Aerodynamic Parameters Estimation (APE) of one pair ON-OFF actuator rolling airframe. In the 1st method namely EAM-PSO the aerodynamic par...

Flight test method is the most accurate approach for all flight conditions. Therefore, during last decades, several approaches have been developed for APE based o...

Classic filters are more convenient but they have some limitations: Kalman filter is optimal only for linear systems with Gaussian ...

used in Rezaei (2015) to estimate aerodynamic coefficients of a rolling airframe. Propeller z-force and pitching moment coefficients of a small unmanned aerial vehicle are estimated through a modified PSO in Tieying, Jie, and Kewei (2015), which in, accelerations, deflection angle, and pitch rate are taken as observati...

EBM-PSO algorithm is a two-step strategy: In 1 st step, the aerodynamic forces and moments are estimated, then after passing through a designed smoothing filter, in 2 nd step, aerodynamic parameters are estimated. In EBM-PSO, the aerodynamic parameters are estimated via solving a single optimization algorithm based on ...

airframe is rigid, Vehicle has an axis-symmetric and cruciform shape, so that the moments of inertia I yy (t) and I zz (t) are identical and products of inertia moments can be discarded. Since, vehicle is modeled as symmetric in pitch and yaw planes (Aksu, 2013), the aerodynamic coefficients C y and C n are identical t...

algorithm is developed here. It starts with an initial population of randomly generated particles. For a search problem in a D-dimensional space, a particle represents a potential solution presented by its velocity and position. During a search process, each particle is attracted by its previous best particle (X best )...

this way, each dimension of the search space is normalized to vary between [0, 1] and maximum velocity of particles in each dimension of search space is set to V max = 0.2. Therefore, the velocity vector of the saturated particles is randomized as: The neighborhood structure There are various neighborhood structures li...

According to the quadratic interpolation, the position of the new particle, generated by particle j and two random particles nb1 and nb2, at t-th iteration and j-th dimension of the search space is calculated as: (20) where, x i (t,j), x nb1 (t,j), x nb2 (t,j) and x ne...
