in this paper the design of a biped robot actuated with shape memory alloy (sma) springs with minimum degrees of freedom is presented. sma springs are a class of smart materials that are known for their high power to mass and volume ratios. it was shown that utilizing spring type of smas have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

The moment exponential distribution has recently been generalized by a number of authors. two-parameter alpha power-transformed (APTME) is introduced. In terms fit, the APTME outperforms distribution. Exact expressions for ordinary moments, incomplete and conditional generating function, cumulant information measures are obtained some features. To estimate model parameters, six well-known frequ...

Numerical simulation of self-induced pitch oscillations a segmental-conical body at Mach number M = 2.0 is performed using the mathematical model pitching moment, which includes an ordinary linear differential equation first order. The parameters were determined from condition best agreement between calculated and experimental transient processes angle in time. modeling was also carried out tim...

In this paper, we introduce and study a unitary matrix-valued process which is closely related to the Hermitian matrix-Jacobi process. It precisely defined as product of deterministic self-adjoint symmetry randomly-rotated one by Brownian motion. Using stochastic calculus action symmetric group on tensor powers, derive an ordinary differential equation for moments its fixed-time marginals. Next...

A new generalized family of distributions called the type II exponentiated half logistic-Marshall-Olkin-G distribution is developed. Some special cases model are presented. We explore some statistical properties distributions. The studied include expansion density function, hazard rate and quantile functions, moments, moment generating probability weighted stochastic ordering, order statistics ...

though the meaning of time seems to be the same for all people, it becomes a complicated, important and relative concept in mysticism which cannot be grasped easily because each mystic understands and interprets it differently depending on the states he experiences; even the same mystic may have diverse interpretations of it in various states and conditions. this paper aims to investigate the s...

Classical estimation methods (least squares, the method of moments and maximum likelihood) work well in regular cases such as the exponential family, but outliers can have undue in1uence on these methods. We de3ne population trimmed L-moments (TL-moments) and corresponding sample TL-moments as robust generalisations of population and sample L-moments. TL-moments assign zero weight to extreme ob...
