The ultrastructure of the body wall cuticle in Acrobeles complexus, Cervidellus alutus, and Zeldia punctata was studied as a step toward understanding biological diversity within Cephalobinae, and to discover new characters for phylogeny-based classification of the suborder. In each species the cuticle consists of cortical, median, and basal layers. The cortical layer includes an external trila...

the aim of this paper is to introduce and study a new concept ofstrong double $(a)_ {delta}$-convergent sequence offuzzy numbers with respect to an orlicz function and also someproperties of the resulting sequence spaces of fuzzy   numbers areexamined. in addition, we define the double$(a,delta)$-statistical convergence of fuzzy  numbers andestablish some connections between the spaces of stron...

The earth pressure coefficient (K) determines the nature of (tendency of) deformation granular mass during flow or deposition. When velocity is increasing, K takes its active state Kact and divergent. decreasing, passive Kpas convergent. mathematical relations presented here their 2-D 3-D plots highlight that coefficients strongly depend on internal angle (δ) basal (ϕ) frictions. relation for d...

<p style='text-indent:20px;'>This paper focuses on two-dimensional continuous subsonic-sonic potential flows in a semi-infinitely long nozzle with straight lower wall and an upper which is convergent at the outlet while far fields. It proved that if variation rate of cross section suitably small, there exists unique such sonic curve intersects fixed point velocity flow along normal direct...

In a previous study, the vertical glottal duct length was examined for its influence on intraglottal pressures and other aerodynamic parameters in uniform glottis [J Voice 32, 8–22 (2018)]. This study extends that work convergent angles, shape of during opening phase vocal fold vibration. The computational fluid dynamics code ANSYS Fluent 6.3 used to obtain pressure distributions laminar, incom...

An inverse scattering problem (ISP) for synthetic aperture radar (SAR) data in application to through-the-wall imaging is addressed. In contrast with the conventional algorithms of SAR imaging, which work linearized mathematical model based on Born approximation, fully nonlinear case considered here. To avoid local minima problem, so-called “convexification” globally convergent inversion scheme...

This study simulated the characteristics of fluid flow that passes through Darrieus turbine before installation and testing were carried out. The purpose knowing can determine profile position maximum speed so design placement be improved. research method was out using dynamic computational simulations in three-dimensional form with steady state conditions, discretization second-order, converge...

In [8] and [9] J. Jarník and J.Kurzweil introduced an integration process (called PU-integral) for real valued functions on an interval of n with the use of suitably regularC-partitions of unity, instead of the usual partitions. The PU-integral is nonabsolutely convergent and in dimension one falls properly in between the Lebesgue and the Kurzweil-Henstock integrals. In [4], without assuming an...
