    Density-Aware Outage in Clustered Ad Hoc Networks
    (Ieee, 2018) Eroglu, Alperen; Onur, Ertan; Turan, Mehmet
    Density of ad hoc networks may vary in time and space because of mobile stations, sleep scheduling or failure of nodes. Resources such as spectrum will be wasted if the network is not density-aware and -adaptive. Towards this aim, distributed and robust network density estimators are required. In this paper, we propose a novel cluster density estimator in random ad hoc networks by employing distance matrix. Monte-Carlo simulation results validate the proposed estimator. The accuracy of the estimator is impressive even under a high amount of distance measurement errors. We also propose a network outage model and a transmit power adaption technique that are density-aware. The results indicate the necessity of the density-aware solutions for making network performance better from capacity, coverage and energy conservation viewpoints.

    Bifurcation in a 3d Hybrid System
    (2010) Akhmet,M.U.; Turan,M.
    In this paper, we study a 3 dimensional Hybrid system which involves a switching mechanism such that at the moment of switching the differential equation that governs the mode] is changing. We first show that there is a center manifold and based on the results in [2] we show that the system under investigation has a Hopf bifurcation. An appropriate example is constructed to illustrate the theory. © Dynamic Publishers, Inc.

    Q-bernstein Polinomlarının Özellikleri Üzerine
    (2017) Almesbahı, Manal Mastafa; Turan, Mehmet; Ostrovska, Sofıya
    Bu tezin amacı Bernstein polinomları teorisini ve son genişletmesi olan q-kalkülüsü çalışmaktır. Bu çalışmanın temel odak noktası 20 yıl önce ortaya çıkan ve kısa sürede birçok araştırmacının dikkatini çeken q-Bernstein polinomlarıdır. Bu tez Bernstein polinomlarına dair bilinen bazı sonuçların derlemesinden, q-Bernstein polinomları teorisine kısa bir giriş ve bazı yeni gelişmelerden oluşmaktadır. Yeni gelişmeler kısmında; limit q-Bernstein operatör dizisinin kuvvetli operatör limiti ve q-Bernstein operatörlerinin zayıf Picard operatörler oldukları ifade edilmiştir.

    Fedja’s Proof of Deepti’s Inequality
    (Tubitak Scientific & Technological Research Council Turkey, 2018) Ostrovska, Sofiya; Turan, Mehmet
    The paper aims to present, in a systematic way, an elegant proof of Deepti’s inequality. Both the inequalityand various ideas concerning the issue were discussed on the Mathoverflow website by a number of users, but none haveappeared in the literature thus far. In this work, suggestions pertaining to users ‘Deepti’ and ‘fedja’ are traced, whencethe title. The results or the paper are new, and the proof is divided into a series of statements, many of which are ofinterest in themselves.

    On the Powers of the Kummer Distribution
    (Academic Publication Council, 2017) Ostrovska, Sofiya; Turan, Mehmet; Mathematics
    The Kummer distribution is a probability distribution, whose density is given by f (x) = cx (alpha-1)(1 + delta x)(-gamma) e(-beta x), X > 0, where alpha, beta, delta > 0, gamma is an element of R and C is a normalizing constant. In this paper, the distributions of random variable X-P, p > 0, where X has the Kummer distribution, are considered with the conditions being IFR/DFR, some properties of moments depending on the parameters and the moment-(in) determinacy. In the case of moment-indeterminacy, exemplary Stieltjes classes are constructed.

    İkinci Mertebeden Lineer Olmayan Bir Fark Denkleminin Dinamikleri Üzerine
    (2014) Aksoy, Aycan; Turan, Mehmet
    Bu tezde iki keyfi parametre içeren ikinci dereceden özel bir rasyonel fark denklemi ele alınmıştır. Bu denklem bazı dinamik yapıları incelenmiştir: pozitif çözümlerin kararlılık ve yarı döngü analizleri; periyodik çözümlerin varlığı; denge noktasının yerel ve global kararlılık analizleri yapılmıştır. Bu tez dört bölümden oluşmaktadır. İlk bölümde fark denklemleri hakkında tarihsel bilgi, bunların bazı modellemeleri, ve yakın zamanda yapılmış bazı çalışmalar verilmiştir. İkinci bölümde, diziler ve fark denklemleriyle ilgili bilinen tanımlar ve sonuçlar gösterilmiştir. Asıl sonuçlar Bölüm 3'te sunulmuştur. Son bölümde kısa bir sonuç yazılmıştır.

    Merkezi Örüntü Üreteçlerin Optimizasyonu
    (2018) Elborı, Alftah; Turan, Mehmet; Arıkan, Kutluk Bilge
    Günümüzde insanlar gibi dinamik ve sağlam hareket edebilen insan robotunu bulmak en zor görevlerden biridir. İki ayaklı hareketi araştıran birçok araştırma olmasına rağmen, günümüzde insan yetenekleri olan robot bulunmamaktadır. Bu tezde robotlarda iki ayaklı hareket için Merkezi Örüntü Üreteçlerin (CPG) optimizasyonu ile ilgili olarak, üç matematiksel yapı tartışılmıştır. Ayrıca, bu tezde iki serbestlik dereceli bir bacakta ritmik hareket elde etmek için CPG'lerin, bağlantısız, tek yönlü veya çift yönlü bağlantılı gibi farklı şekillerde eşleşmeleri incelenmiştir. CPG'lerin üç matematiksel yapısı için de kararlılık analizi yapılmıştır. Bu tezde ele alınan farklı yapılardaki farklı eşleştirmeler arasından üçüncü yapıda çift yönlü eşleştirme en iyi sonucu vermiştir. Yapılardaki parametreler kararlılık bölgesinden seçildiği zaman, herhangi bir duyusal geribildirim olmaksızın önemli sonuçların elde edildiği gözlemlenmiştir.

    Qualitative results on the convergence of the q-Bernstein polynomials
    (North Univ Baia Mare, 2015) Ostrovska, Sofiya; Turan, Mehmet
    Despite many common features, the convergence properties of the Bernstein and the q-Bernstein polynomials are not alike. What is more, the cases 0 < q < 1 and q > 1 are not similar to each other in terms of convergence. In this work, new results demonstrating the striking differences which may occur in those convergence properties are presented.

    q-stieltjes Classes for Some Families of q-densities
    (Elsevier Science Bv, 2019) Ostrovska, Sofiya; Turan, Mehmet
    The Stieltjes classes play a significant role in the moment problem allowing to exhibit explicitly infinite families of probability densities with the same sequence of moments. In this paper, the notion of q-moment determinacy/indeterminacy is proposed and some conditions for a distribution to be either q-moment determinate or indeterminate in terms of its q-density have been obtained. Also, a q-analogue of Stieltjes classes is defined for q-distributions and q-Stieltjes classes have been constructed for a family of q-densities of q-moment indeterminate distributions.
