(2010) Savaş, Ekrem; Taş, Selma; Duru, Adem
Bu çalışmada ilköğretim 6–7–8 sınıflardaki öğrencilerin matematik başarılarını etkileyen faktörler araştırılmıştır. Bu amaçla okul türü, ailenin gelir düzeyi, öğrencinin ders çalışma süresi, matematiğe yönelik tutum ve dershaneye gitme gibi faktörler ile öğrencilerin matematik başarıları arasındaki ilişki araştırılmıştır. Çalışmanın örneklemi Van ilindeki bir özel okuldan (58) ve iki devlet okulundan (217) rastgele seçilen toplam 275 öğrenciden oluşmuştur. Verilerin analizi için SPSS paket programı kullanılarak Ki-Kare analizi yapılmıştır. Araştırmanın bulgularına göre okul türü, ailenin gelir düzeyi, ders çalışma süresi, matematiğe yönelik tutum ve dershaneye gitme ile matematik başarısı arasında bir ilişkinin olduğu görülmüş ve son olarak ta araştırmanın bulguları doğrultusunda bazı önerilerde bulunulmuştur.
λ-statistical convergence in n-normed spaces
(2013) Hazarika, Bipan; Savaş, Ekrem
In this paper, we introduce the concept of ?-statistical convergence in n-normed spaces. Some inclusion relations between the sets of statistically convergent and ?-statistically convergent sequences are established. We find its relations to statistical convergence, (C,1)-summability and strong (V, ?)-summability in n-normed spaces.
On ii>θ -statistical convergence of order α in intuitionistic fuzzy normed spaces
(Editura Acad Romane, 2015) Savaş, Ekrem
In this paper, following a very recent and new approach, we introduce the notions of I -statistical convergence and I-theta -statistical convergence of order alpha, where 0 < alpha <= 1, with respect to the intuitionistic fuzzy norm (mu,nu) and we mainly investigate their relationship, and also make some observations about these classes.

Let S* be the class of starlike functions and let SH be the class of harmonic mappings in the plane. In this paper we investigate harmonic mapping related to the starlike functions.
On I-lacunary statistical convergence of weight g of fuzzy numbers
(Ios Press, 2017) Savaş, Ekrem
In this paper, following a very recent and new approach of [1], we discuss a relation between two kinds of I-convergence of sequences, namely, I-statistical convergence of weight g and I-lacunary statistical convergence of weight g, where g : N -> [0, infinity) is a function satisfying lim(n ->infinity) g (n) = infinity and n/g(n) negated right arrow 0 as n -> infinity for fuzzy numbers. These methods are based on the methods of statistical convergence and lacunary Statistical summability for sequences. Analogs of inclusion and consistency theorems for the sequential methods are established.
On asymptotically lacunary σ-statistical equivalent sequences of fuzzy numbers
(World Scientific Publ Co Pte Ltd, 2009) Savaş, Ekrem
This paper presents the asymptotically lacunary sigma-statistical equivalent which is a natural combination of the definition for asymptotically equivalent, invariant mean and lacunary statistical convergence of fuzzy numbers. In addition, we shall also present asymptotically lacunary sigma-statistical equivalent analogs of Savas and Nuray's theorems in Ref. 8.
Generalized statistical convergence and statistical core of double sequences
(Springer Heidelberg, 2010) Mursaleen, Mohammad; Çakan, Celal; Mohiuddine, Syed Abdul; Savaş, Ekrem
In this paper we extend the notion of lambda-statistical convergence to the (lambda, A mu)statistical convergence for double sequences x = (x (jk) ). We also determine some matrix transformations and establish some core theorems related to our new space of double sequences S (lambda,A mu).

(Pergamon-Elsevier Science Ltd, 2013) Polat, Recep; İçelli, Orhan; Yalçın, Zeynel; Pesen, Erhan; Orak, Salim
59.5 keV gamma rays scattered by an aluminum foil have been used as a radiation source to measure the absorption jump factor and jump ratios for absorbers Ce, Pr, Nd, Sm, Eu and Tb. The theoretical and experimental values are compared with the corresponding ones in the literature.
(A)Δ - double sequence spaces of Fuzzy numbers via orlicz function
(Univ Sistan & Baluchestan, 2011) Savaş, Ekrem
The aim of this paper is to introduce and study a new concept of strong double (A)(Delta)-convergent sequence of fuzzy numbers with respect to an Orlicz function and also some properties of the resulting sequence spaces of fuzzy numbers are examined. In addition, we define the double (A, Delta)-statistical convergence of fuzzy numbers and establish some connections between the spaces of strong double (A)(Delta)-convergent sequence and double (A, Delta)-statistical convergent sequence.
Asymptotic equivalence of double sequences
(2012) Patterson, Richard F.; Savaş, Ekrem
The goal of this paper is to present a four-dimensional matrix characterization of asymptotic equivalence of double sequences. This will be accomplished with the following notion of asymptotic equivalence of double sequences. Two double sequences are asymptotic equivalent if and only if P − limk,l xk,l yk,l = 1, where x and y are selected judicially. Using this notion necessary and sufficient conditions on the entries of a four-dimensional matrix are given to ensure that the transformation will preserve asymptotic equivalence.
Remark on double lacunary statistical convergence of fuzzy numbers
(Eudoxus Press, LLC., 2009) Savaş, Ekrem
Y. Altin proved the inclusion relations between the sets of the double statistically convergent and double lacunary statistically convergent sequences of fuzzy numbers. In this paper we show that Altin's condition is suffcient as well as necessary.

Developing computational fluency with the help of science: A Turkish middle and high school grades study
(Turkish Online Journal Educational Tech-Tojet, 2011) Çorlu, Mehmet Sencer; Capraro, Robert M.; Çorlu, Mehmet Ali
Students need to achieve automaticity in learning mathematics without sacrificing conceptual understanding of the algorithms that are essential in being successful in algebra and problem solving, as well as in science. This research investigated the relationship between science-contextualized problems and computational fluency by testing an instructional method that was implemented as a non-traditional drill exercise. The study employed a quantitative analysis of pre- and post-test scores of Turkish middle and high school students after two interventions. The questions addressed were: Do the science-contextualized drill practices (SCP) improve students' computational fluency better than traditional drill practices (TP)? Is there any statistical significance between middle and high school students in terms of their benefit from SCP? This study showed that sciencecontextualized drill exercises produced higher gains for both middle and high school students' computational fluencies than the traditional context-free drill exercises.
Neutrosophic metric spaces
(Springer, 2020) Kirişçi, Murat; Şimşek, Necip
Neutrosophy consists of neutrosophic logic, probability, and sets. Actually, the neutrosophic set is a generalisation of classical sets, fuzzy set, intuitionistic fuzzy set, etc. A neutrosophic set is a mathematical notion serving issues containing inconsistent, indeterminate, and imprecise data. The notion of intuitionistic fuzzy metric space is useful in modelling some phenomena where it is necessary to study the relationship between two probability functions. In this paper, the definition of new metric space with neutrosophic numbers is given. Neutrosophic metric space uses the idea of continuous triangular norms and continuous triangular conorms in intuitionistic fuzzy metric space. Triangular norms are used to generalize with the probability distribution of triangle inequality in metric space conditions. Triangular conorms are known as dual operations of triangular norms. Triangular norms and triangular conorm are very significant for fuzzy operations. Neutrosophic metric space was defined with continuous triangular norms and continuous triangular conorms. Several topological and structural properties neutrosophic metric space have been investigated. The analogues of Baire Category Theorem and Uniform Convergence Theorem are given for Neutrosophic metric spaces.

(Springer, 2007) Savaş, Ekrem
We obtain sufficient conditions on a nonnegative lower triangular matrix A and a sequence lambda(n) for the series Sigma a(n)lambda(n)/na(nn) to be absolutely summable of order k >= 1 by A. Copyright (c) 2007 E. Savas, and B. E. Rhoades.
On general summability factor theorems
(Springer International Publishing AG, 2007) Savaş, Ekrem
The goal of this paper is to obtain sufficient and (different) necessary conditions for a series Sigma a(n), which is absolutely summable of order k by a triangular matrix method A, 1 < k <= s < infinity, to be such that Sigma a(n)lambda(n) is absolutely summable of order s by a triangular matrix method B. As corollaries, we obtain two inclusion theorems.

On the cesaro summability of double series
(Springer International Publishing AG, 2008) Savaş, Ekrem; Şevli, Hamdullah; Rhoades, B. E.
In a recent paper by Savas, and Sevli (2007), it was shown that each Cesaro matrix of order alpha, for alpha > -1, is absolutely kth power conservative for k >= 1. In this paper we extend this result to double Cesaro matrices. Copyright (C) 2008.
