Distance Fibonacci Polynomials by Graph Methods

In this paper we introduce and study a new generalization of Fibonacci polynomials which generalize Fibonacci, Jacobsthal and Narayana numbers, simultaneously. We give a graph interpretation of these polynomials and we obtain a binomial formula for them. Moreover by modification of Pascal’s triangle, which has a symmetric structure, we obtain matrices generated by coefficients of generalized Fibonacci polynomials. As a consequence, the direct formula for generalized Fibonacci polynomials was given. In addition, we determine matrix generators for generalized Fibonacci polynomials, using the symmetric matrix of initial conditions.

Comparing traditional and constrained disturbance-observer based positional control

This paper compares three different position controllers of electrical drives equipped by binomial [Formula: see text] th order filters, which are offering filtering properties important in a quantization noise attenuation. To demonstrate their impact, a non-filtered P-PI control is considered, as a reference. The comparative framework includes a filtered P-PI control, a filtered linear pole assignment PD controllers with a disturbance observer (DO) based integral action and its constrained modification. In terms of a total variation, depending on noise and process properties, all filtered controllers are capable to bring down the undue controller activity at the plant input from 10 to more than 100 times. Furthermore, thanks to the applied disturbance observer, the constrained control derived for a double integrator is shown to fully exploit the closed loop capabilities without any trajectory generation, taking into account the control constraints. Thus, the simplified controller design may focus on other important aspects.

Аннотация: Биздин заманда билим алууга болгон көз караш өзгөрдү: мурун маалымат алуу абдан маанилүү болсо, азыр маалыматтарды колдонууну билиш керек. Себеби, азыркы турмушта Google сыяктуу маалымат булактары бар. Биз биргелешкен математика курсу синергияны пайда кылып, алгебра менен геометриянын элементтерин өздөштүрүүгө жардам берет деп ишенебиз. Алгебралык, дифференциалдык жана интегралдык теӊдемелердин жакындаштырылган чыгарылыштарын тургузууда жана ошондой эле ар кандай интегралдарды баалоодо параметрдин же көз карандысыз өзгөрүлмөнүн даражасы бар катарлар менен иштөөгө туура келет. Негизинен даражалуу катарга ажыратуу Ньютондун биномунун формуласынын жардамы менен же Тейлордун катарын колдонуу жолу аркылуу тургузулат. Бул илимий макалада ошол тууралуу сөз болот.

Аннотация: В области математики знание точных формулировок определений, теорем и т.п. теперь не столь важно, как умение их использовать для решения задач, связанных с окружающей действительностью. Мы убеждены в том, что курс математики, объединяющий элементы алгебры и геометрии поможет повысить уровень усвоения материала за счет эффекта синергии, возникающего при этом. При построении приближенных решений алгебраических, дифференциальных и интегральных уравнений, а также при оценке различных интегралом нам приходится иметь дело с рядами по степеням параметра или независимой переменной. Такие разложения в степенные ряды строятся обычно либо с помощью формулы бинома Ньютона, либо путем использования рядов Тейлора. О них и пойдет речь ниже. Ключевые слова: Ряд Тейлора, ряд Маклорена, разложения в ряд, Показательная функция, тригонометрические функции, сумма, интервал, на всей действительной оси, сходящийся ряд, формула Коши-Адамара, остаточный член в формуле Лагранжа, биноминальный ряд с показателем , логарифмическая функция, равенства, свойства, значение аргумента, степень, точность, порядок, оценка. Аnnotation: Nowadays, getting general information is easy an ditisim portant to beable to correctly interpretand use existing data. In the field of mathematics, knowledge of exact formulations of definitions, theorems, etc. now it is not so important as the ability to use them for solving problems related to the surround dingreality. We are convinced that the course of mathematics, combining the elements of Algebra and Geometry, will help to in crease the level of mastering matterdueto the synergy effect thatarises. In constructing approximate solutions of algebraic differential, and integral equations, as well as in estimating various integrals, we have to deal with series in powers of a parameter or an independent variable. Such power series expansions are usually constructed either using the Newton binomial formula, or by using the Taylor series. About them find it below.

Research on some new results arising from multiple q-calculus

In this paper, we develop the theory of the multiple q-analogue of the Heine?s binomial formula, chain rule and Leibniz?s rule. We also derive many useful definitions and results involving multiple q-antiderivative and multiple q-Jackson?s integral. Finally, we list here multiple q-analogue of some elementary functions including trigonometric functions and hyperbolic functions. This may be a good consideration in developing the multiple q-calculus in combinatorics, number theory and other fields of mathematics.

On Subnomials

Summary While discussing the sum of consecutive powers as a result of division of two binomials W.W. Sawyer [12] observes “It is a curious fact that most algebra textbooks give our ast result twice. It appears in two different chapters and usually there is no mention in either of these that it also occurs in the other. The first chapter, of course, is that on factors. The second is that on geometrical progressions. Geometrical progressions are involved in nearly all financial questions involving compound interest – mortgages, annuities, etc.” It’s worth noticing that the first issue involves a simple arithmetical division of 99...9 by 9. While the above notion seems not have changed over the last 50 years, it reflects only a special case of a broader class of problems involving two variables. It seems strange, that while binomial formula is discussed and studied widely [7], [8], little research is done on its counterpart with all coefficients equal to one, which we will call here the subnomial. The study focuses on its basic properties and applies it to some simple problems usually proven by induction [6].
