Solitary waves in fluid-filled elastic tubes: weakly dispersive case

Demiray, Hilmi (Pergamon-Elsevier Science, 2001-03)

In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and the approximate equations of an incompressible inviscid fluid, the propagation of weakly nonlinear waves, in ...

Some boundary Harnack principles with uniform constants

Barlow, Martin T.; Karlı, Deniz (Springer Science and Business Media B.V., 2022-10)

We prove two versions of a boundary Harnack principle in which the constants do not depend on the domain by using probabilistic methods.

Some inequalities which hold for starlike log-harmonic mappings of order alpha

Özkan Uçar, Hatice Esra; Aydoğan, Seher Melike (Eudoxus Press, LLC., 2014-04)

Let H(D) be the linear space of all analytic functions defined on the open disc D = {z vertical bar vertical bar z vertical bar < 1}. A log-harmonic mappings is a solution of the nonlinear elliptic partial differential ...

Some notes on spectra of cographs

Bıyıkoğlu, Türker; Simic, Slobodan K.; Stanic, Zoran (Charles Babbage Res Ctr, 2011-07)

A cograph is a P-4-free graph. We first give a short proof of the fact that 0 (-1) belongs to the spectrum of a connected cograph (with at least two vertices) if and only if it contains duplicate (resp. coduplicate) vertices. ...

Some properties concerning close-to-convexity of certain analytic functions

Nunokawa, Mamoru; Aydoğan, Seher Melike; Kuroki, Kazuo; Yıldız, İsmet; Owa, Shigeyoshi (Springer International Publishing AG, 2012)

Let f(z) be an analytic function in the open unit disk D normalized with f(0) = 0 and f'(0) = 1. With the help of subordinations, for convex functions f(z) in D, the order of close-to-convexity for f(z) is discussed with ...

Some properties of starlike harmonic mappings

Aydoğan, Seher Melike; Yemişçi, Arzu; Polatoğlu, Yaşar (Springer International Publishing AG, 2012)

A fundamental result of this paper shows that the transformation F=az(h(z+a/1+(a) over barz) + /(h(a) + <(g(a))over bar>(z + a) (1 + (a) over barz) defines a function in S0 HS* whenever f = h( z) + g( z) is S0 HS*, andwewill ...

Some results on a starlike log-harmonic mapping of order alpha

Aydoğan, Seher Melike (Elsevier Science BV, 2014-01-15)

Let H(D) be the linear space of all analytic functions defined on the open unit disc D = z is an element of C : vertical bar z vertical bar < 1. A sense preserving log-harmonic mapping is the solution of the non-linear ...

Some results on a subclass of harmonic mappings of order alpha

Varol, Dürdane; Aydoğan, Seher Melike; Owa, Shigeyoshi (Işık University Press, 2014)

Let SH be the class of harmonic mappings defined by SH = { f = h(z) + g(z)| h(z) = z + ?? n=2 anz?, g(z) = b1z + ?? n=2 bnz?, b1 < 1 } where h(z) and g(z) are analytic. Additionally f(z) ? SH(?) ? | zh? (z) ? zg?(z) h(z) ...

Sorption and slow release kinetics of PAAM gels at various temperatures

Evingür, Gülşen Akın; Pekcan, Mehmet Önder (Freund Publishing House Ltd, 2007-11)

Small molecule sorption and slow release in and out of polyacrylamide (PAAm) gels were studied by using steady state fluorescence (SSF) technique. Pyranine (P-y) dissolved in water used as a probe. Fluorescence emission ...

Sönümlemeli sistemlerin eşlenmesi üzerine

Esen, Oğul; Özcan, Gökhan; Sütlü, Serkan (Afyon Kocatepe Üniversitesi, 2021)

Bu makalede karşılıklı etki tepki içindeki iki sönümlemeli sistemin beraber (kollektif- eşlenmiş) hareketinin analizi üzerine bir yöntem öneriyoruz. Aşikardır ki; eşlenmiş hareketi kontrol eden diferansiyel denklemler iki ...

Space, time, and iconicity in Turkish sign language (tid)

Arık, Engin (Estonian Academy Publishers, 2012)

Much evidence points to the conclusion that temporal concepts are drawn primarily from the conceptualization of space. Sign languages provide a particularly suitable area for observing such a relationship since they employ ...

Space-like surfaces in the Minkowski Space E-1(4) with pointwise 1-type Gauss maps

Dursun, Uğur; Turgay, Nurettin Cenk (Springer, 2019-06)

We first classify space-like surfaces in the Minkowski space E-1(4), de Sitter space S-1(3), and hyperbolic space H-3 with harmonic Gauss maps. Then we characterize and present a classification of the space-like surfaces ...

Dursun, Uğur; Bektaş, Burcu (Springer, 2014-06)

In this paper, we consider a class of spacelike rotational surfaces in Minkowski space E-1(4) with 2-dimensional axis. There are three types of rotational surfaces with 2-dimensional axis, called rotational surfaces of ...

Spatial extent of precipitation events: when big is getting bigger

Matte, Dominic; Christensen, Jens Hesselbjerg; Öztürk, Tuğba (Springer Science and Business Media Deutschland GmbH, 2022-03)

Using a sub-selection of regional climate models at 0.11 degrees (approximate to 12 km) grid resolution from the EURO-CORDEX ensemble, we investigate how the spatial extent of areas associated with the most intensive daily ...
