Let u be a function of several real variables (t, x 1, x 2, …, x n ): $$ \begin{gathered} u:\mathbb{R}^ + \times \mathbb{R}^n \quad \,\, \to \mathbb{R} \hfill \\ \left( {t,x_1 ,x_2 , \ldots ,x_n } \right) \mapsto u\left( {t,x_1 ,x_2 , \ldots ,x_n }

Fall recovery after falling over is a critical feature for biped robots that work in the real world. We propose a method by considering robot joint angle trajectory as a multivariable function of time and orientation of robot root links. Compared wit

A method for constructing a Chebyshev approximation of the multivariable functions by exponential, logarithmic and power expressions is proposed. It consists in reducing the problem of the Chebyshev approximation by a nonlinear expression to the cons

We propose two algorithms for solving global optimization problems on a hyperrectangle with an objective function satisfying the Vanderbei condition (this function is also called an $\varepsilon$-Lipschitz continuous function). The algorithms belong

A method for constructing the Chebyshev approximation of multivariable functions by an exponential expression with a relative error is proposed. It generates an intermediate Chebyshev approximation of the values of the logarithm of a function by a po

Mechanical processes occurring in paper production are modeled. In a papermaking machine, paper moves in the form of a thin sheet. The characteristic thickness of a sheet varies from 0.1 mm (office paper) to 1 mm (cardboard). Every papermaking machin

A pair of the complex-valued sequences is called a $Z$ -complementary pair (ZCP) if it has zero aperiodic auto-correlation sum (AACS) for all time-shifts within a certain region, commonly known as zero correlation zone (ZCZ). Type-II ZCPs have the ZC
