CONCURRENTLY CONTROLLED GRAMMARS

Mavlankulov, Gairatzhan; Othman, Mohamed; Turaev, Sherzod; Hasan Selamat, Mohd; Zhumabayeva, Laula; Zhukabayeva, Tamara (Kybernetika, 2018)

This paper introduces a new variant of Petri net controlled grammars, namely a concurrently controlled grammar, where the control over the application of the productions of a grammar is realized by a Petri net with ...
Creating and Using Mobile Physics and Mathematics Applications in the Learning Process as One of Teaching Methods to Increase the Quality of Student’s Knowledge

On the Feasibility of Interference Alignment in Compounded MIMO Broadcast Channels With Antenna Correlation and Mixed User Classes

Nauryzbayev, Galymzhan; Alsusa, Emad; Abdallah, Mohamed (IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, 2018)

This paper presents a generalized closed-form beamforming technique that can achieve the maximum degrees of freedom in compounded multiple-input multiple-output (MIMO) broadcast channels with mixed classes of multiple-antenna ...
One-Dimensional Schrodinger Operator with a Negative Parameter and Its Applications to the Study of the Approximation Numbers of a Singular Hyperbolic Operator

Muratbekov, M.B.; Muratbekov, M.M. (Faculty of Sciences and Mathematics, 2018)

In this paper we use the one-dimensional Schrodinger operator with a negative parameter to the ¨ study of the approximation numbers of a hyperbolic type singular operator. Estimates for the distribution function of the ...
Hardy-Littlewood, Hausdorff-Young-Paley inequalities, and Lp-Lq Fourier multipliers on compact homogeneous manifolds

Akylzhanov, Rauan; Ruzhansky, Michael; Nursultanov, Erlan (Journal of Mathematical Analysis and Applications, 2019)
About one approach to solving the inverse problem for parabolic equation

Zhabko, A. P.; Nurtazina, K. B.; Provotorov, V. V. (Vestnik of Saint Petersburg University. Applied Mathematics. Computer Science. Control Processes, 2019)

Consider the problem of determining the coefficients in the differential equation of parabolic types and boundary conditions on the known sections of the solutions of the initial-boundary value problem. Used spectral ...
DEVELOPMENT OF THE ALGORITHM OF KEYWORD SEARCH IN THE KAZAKH LANGUAGE TEXT CORPUS

Akanova, А.; Ospanova, N.; Kukharenko, Y.; Abildinova, G. (Eastern-European Journal of Enterprise Technologies, 2019)
Information Security Risk Assessment in Critical Infrastructure: A Hybrid MCDM Approach

TURSKIS, Zenonas; GORANIN, Nikolaj; NURUSHEVA, Assel; BORANBAYEV, Seilkhan (INFORMATICA, 2019)

The risk analysis has always been one of the essential procedures for any areas. The majority of security incidents occur because of ignoring risks or their inaccurate assessment. It is especially dangerous for critical ...
Kernel oper ernel operators and their boundedness fr ors and their boundedness from weighted Sobole om weighted Sobolev space to weighted Lebesgue space

KALYBAY, AIGERIM; OINAROV, RYSKUL (Turkish Journal of Mathematics, 2019)

In this paper, for a wide class of integral operators, we consider the problem of their boundedness from a weighted Sobolev space to a weighted Lebesgue space. The crucial step in the proof of the main result is to use ...
INTEGRAL OPERATORS WITH TWO VARIABLE INTEGRATION LIMITS ON THE CONE OF MONOTONE FUNCTIONS

KALYBAY, AIGERIM; OINAROV, RYSKUL; TEMIRKHANOVA, AINUR (Journal of Mathematical Inequalities, 2019)
ON A KUDRYAVTSEV TYPE FUNCTION SPACE

Kalybay, A.A.; Keulimzhayeva, Zh.A.; Oinarov, R. (EURASIAN MATHEMATICAL JOURNAL, 2019)
Wiener–Beurling spaces and their properties

Nursultanov, Erlan; Tikhonov, Sergey (Bulletin des Sciences Mathématiques, 2020)

In this paper, we introduce the Wiener–Beurling space, which generalize the Wiener space of absolutely convergent Fourier series, the Berling space as well as the Cesàro and Copson spaces. We investigate their main ...
Well-posedness of heat and wave equations generated by Rubin’s q-difference operator in Sobolev spaces

Shaimardan, Serikbol; Persson, Lars-Erik; Tokmagambetov, Niyaz (Faculty of Sciences and Mathematics, 2020)

In this paper, we investigate difference-differential operators of parabolic and hyperbolic types. Namely, we consider non-homogenous heat and wave equations for Rubin’s difference operator. Wellposedness results are ...
Multidimensional inverse Cauchy problems for evolution equations

Karazym, Mukhtar; Ozawa, Tohru; Suragan, Durvudkhan (INVERSE PROBLEMS IN SCIENCE AND ENGINEERING, 2020)

We discuss inverse problems to finding the time-dependent coefficient for the multidimensional Cauchy problems for both strictly hyperbolic equations and polyharmonic heat equations. We also extend our techniques to the ...
CORRECT SINGULAR PERTURBATIONS OF THE LAPLACE OPERATOR

Biyarov, B.N.; Svistunov, D.L.; Abdrasheva, G.K. (EURASIAN MATHEMATICAL JOURNAL, 2020)

The work is devoted to the study of the Laplace operator when the potential is a singular generalized function and plays the role of a singular perturbation of the Laplace operator. Abstract theorem obtained earlier by ...
Development and Analysis of Models for Assessing Predicted Mean Vote Using Intelligent Technologies

Sansyzbay, L. Zh.; Orazbayev, B. B.; Wojcik, W. (International Journal of Fuzzy Logic and Intelligent Systems, 2020)

One of the approaches toward determining the degree of microclimate comfort is measuring its individual components: temperature, air velocity, relative humidity, and air quality. A significant disadvantage of this approach ...
DEVELOPMENT OF A METHOD FOR STUDYING GAS IMBALANCE IN THE SECTION OF THE MAIN GAS PIPELINE OF KAZAKHSTAN
