Recent review article by S. Samuel ”On the speed of gravity and the Jupiter/Quasar measurement” published in the International Journal of Modern Physics D, 13 (2004) 1753, provides the reader with a misleading ”theory” of the relativistic time delay in general theory of relativity. Furthermore, it misquotes original publications by Kopeikin and Fomalont & Kopeikin related to the measurement of ...
a heyting algebra is a distributive lattice with implication and a dual $bck$-algebra is an algebraic system having as models logical systems equipped with implication. the aim of this paper is to investigate the relation of heyting algebras between dual $bck$-algebras. we define notions of $i$-invariant and $m$-invariant on dual $bck$-semilattices and prove that a heyting semilattice is equiva...
In this paper, real time implementation of PI and PID controllers is Investigated for stabilizing an arbitrary-order plant or system. Simple closed loop feedback ,PI controller can overcome all the problems of uncertainties like time delay in LTI (Linear Time Invariant) system.This paper will give us an implortant alogorithm to be imlemented in MATLAB for achieving the robust stability in LTI p...
Let G=(V,E) be a graph where v(G) and E(G) are vertices and edges of G, respectively. Sum of distance between vertices of graphs is called wiener invariant. In This paper, we present some proved results on the wiener invariant and some new result on the upper bound of wiener invariant of k-connected graphs.
A Heyting algebra is a distributive lattice with implication and a dual $BCK$-algebra is an algebraic system having as models logical systems equipped with implication. The aim of this paper is to investigate the relation of Heyting algebras between dual $BCK$-algebras. We define notions of $i$-invariant and $m$-invariant on dual $BCK$-semilattices and prove that a Heyting semilattice is equiva...
Invariance principles is one of the ways to summarize sample information and by these principles invariance or equivariance decision rules are used. In this paper, first, the methods for finding the maximal invariant function are introduced. As a new method, maximal invariant statistics are constructed using equivariant functions. Then, using several equivariant functions, the maximal invariant...
Lifting modules and their various generalizations as some main concepts in module theory have been studied and investigated extensively in recent decades. Some authors tried to present some homological aspects of lifting modules and -supplemented modules. In this work, we shall present a homological approach to -supplemented modules via fully invariant submodules. Lifting modules and H-suppleme...
We construct a data-driven dynamical system model for macroscopic variable the Reynolds number of high-dimensionally chaotic fluid flow by training its scalar time-series data. use machine-learning approach, reservoir computing construction model, and do not knowledge physical process dynamics in procedure. It is confirmed that an inferred obtained from approximates actual one each various time...
In this paper, the stability robustness is considered for linear time invariant (LTI) fractional order systems with time delay against delay uncertainties. The complexity arises due to the exponential type transcendental terms and fractional order in their characteristic equation. We show that this procedure numerically reveals all possible stability regions exclusively in the space of the dela...
