muscle fatigue assessment has been the basis of numerous studies, specifically, in neuromuscular rehabilitation and the applications of fessystems. various emgbased techniques, in time and frequency domains, have been investigatedover years for the detection and evaluationof this phenomenon. the main objective of this study has beento evaluate the efficiency of applying a number of techniques w...

We use $\Delta$SYM-H to capture the variation in SYM-H index during main phase of a geomagnetic storm. define great storms as those with $\le$ -200 nT. After analyzing data that were not obscured by solar winds, we determined 11 such occurred cycle 23. calculated time integrals for southward interplanetary magnetic field component I(B$_s$), wind electric I(E$_y$), and combination E$_y$ dynamic ...

Structural behaviour of PbMn$_{7}$O$_{12}$ has been studied by high resolution synchrotron X-ray powder diffraction. This material belongs to a family quadruple perovskite manganites that exhibit an incommensurate structural modulation associated with orbital density wave. It found the in onsets at 294 K propagation vector $\mathbf{k}_s=(0,0,\sim2.08)$. At 110 another transition takes place whe...

Let $$S= \{ p_1, \ldots, p_s\}$$ be a finite, non-empty set of distinct prime numbers and $$(U_{n})_{n \geq 0}$$ linear recurrence sequence integers order at least 2. For any positive integer k, $$w = (w_k, w_1)\in\mathbb{Z}^k, w_1, w_k\neq 0$$ we define $$(U_j^{(k, w)})_{j\geq 1}$$ an increasing composed the form $$|w_kU_{n_k} +\cdots + w_1U_{n_1}|$$ , $$ n_k>\cdots >n_1$$ . Under certain assu...

In this note, we consider weighted PLB-spaces of ultradifferentiable functions defined via a weight function and system, as introduced in our previous work (2022). We provide complete characterization when these spaces are ultrabornological barrelled terms the defining thereby improving main result above mentioned work. particular, obtain that multiplier space Gelfand--Shilov $\Sigma^r\_s(\math...

Various aspects of linguistic experience influence the way we segment, represent, and process speech signals. The Japanese phonetic and orthographic systems represent geminate consonants (double consonants, e.g., /ss/, /kk/) in a unique way compared to other languages: one abstract representation is used to characterize the first part of geminate consonants despite the acoustic difference betwe...

Abstract Given a graph G and subset of vertices $$D\subseteq V(G)$$ D ⊆ V ( G ) , the external neighbourhood D is defined as $$N_e(D)=\{u\in V(G){\setminus } D:\, N(u)\cap D\ne \varnothing \}$$ <mml:msu...

jachymski [ proc. amer. math. soc., 136 (2008), 1359-1373] gave modified version of a banach fixed point theorem on a metric space endowed with a graph. in the present paper, (g, φ)-graphic contractions have been de ned by using a comparison function and studied the existence of fixed points. also, hardy-rogers g-contraction have been introduced and some fixed point theorems have been proved. s...
