The Incremental Model Reference Adaptive Polynomial Controllers Network (IMRAPCN) is a self-organising non linear controller. This algorithm consists of a Polynomial Controllers Network (PCN) and an Incremental Network Construction (INC). The PCN is a network of polynomial controllers each one being valid for a diierent operating region of the system. The use of polynomial controllers reduces s...
A 30 W LDMOS is modeled using a 5th order polynomial model. The polynomial model is compared to the largesignal MET model using harmonic balance, and as the results agreed very well, the polynomial model was imported to a numerical Volterra simulator to find out the dominant cause of distortion for a class A biased amplifier. The characterization technique is briefly discussed.
This paper is concerned with the automated complexity analysis of term rewrite systems (TRSs for short) and the ramification of these in implicit computational complexity theory (ICC for short). We introduce a novel path order with multiset status, the polynomial path order >pop∗. Essentially relying on the principle of predicative recursion as proposed by Bellantoni and Cook, its distinct feat...
This paper describes a parser for German, which treats major phenomena of word order including scrambling, (partial) VP fronting and extraposition. The outputs of the parser are dependency trees and topological phrase structures. We use the CKY parsing algorithm, which is polynomial with some bounds on the number of emancipations (that is, constituents that are positioned outside of the domain ...
Introduction: This study analyses the risk factors that affect glycosylated hemoglobin index in type 2 diabetes mellitus. The purpose of this study was to determine the relative importance of each factor and design a polynomial model for predicting blood glucose levels according to the factors influencing it. Methods: In this study, risk factors including weight, systolic and diastolic blood p...
In this paper we consider two type of mathematical models for the novel coronavirus (2019-nCov), which are in the form of a nonlinear differential equations system. In the first model the contact rate, , and transition rate of symptomatic infected indeviduals to the quarantined infected class, , are constant. And in the second model these quantities are time dependent. These models are the...
abstract: aqueous enzymatic extraction of oil from pistacia khinjuk was performed using cellulase. the central composite design was used to optimize the parameters that are significant to the process. the influence of three regressors on the percentage of oil recovery from seed was evaluated using second-order polynomial multiple regression model. analysis of variance showed a high coefficient ...
For every $1leq s< n$, the $s^{th}$ derivative of a polynomial $P(z)$ of degree $n$ is a polynomial $P^{(s)}(z)$ whose degree is $(n-s)$. This paper presents a result which gives generalizations of some inequalities regarding the $s^{th}$ derivative of a polynomial having zeros outside a circle. Besides, our result gives interesting refinements of some well-known results.
