An application of soft Set and fuzzy soft Set theories to stock management
Taş, Nihal; Özgür, Nihal Yılmaz; Demir, Pelin (2017)We give a new application of both notions of a soft set and of a fuzzy soft set to the effective management of stock-out situation. We construct a model to track the remaining raw materials in stock at the end of the first ... -

Bilateral-type solutions to the fixed-circle problem with rectified linear units application
Taş, Nihal (Scientific Technical Research Council Turkey-Tubitak, 2020)In this paper, we prove new fixed-circle (resp. fixed-disc) results using the bilateral type contractions on a metric space. To do this, we modify some known contractive conditions called the Jaggi-type bilateral contraction ... -
Binary soft set theory
Açıkgöz, Ahu; Taş, Nihal (European Journal Pure, 2016)In this paper, we study the concept of soft sets theory which introduced by Molodtsov [9] and the theory of soft sets which studied by Maji et al. [6]. The authors introduce a binary soft set on two initial universal sets ... -
Common fixed point results on complex-valued s-metric spaces
Taş, Nihal; Özgür, Nihal Yılmaz (Univ Maragheh, 2020)Banach's contraction principle has been improved and extensively studied on several generalized metric spaces. Recently, complex-valued S-metric spaces have been introduced and studied for this purpose. In this paper, we ... -
Common fixed points of continuous mappings on s-metric spaces
Taş, Nihal; Özgür, Nihal Yılmaz (Maik Nauka/Interperiodica, 2018)The aim of this paper is to obtain some common fixed point results on an S-metric space. For this purpose, we prove new generalized common fixed point theorems using the notions of weak commutation, compatibility, and ... -
Contra g-alpha- and g-beta-preirresolute functions on GTS's
Açıkgöz, Ahu; Taş, Nihal; Sarsak, Mohammad S. (Springer Heidelberg, 2015)In this present paper, we define g-alpha-preirresolute, g-beta-preirresolute, contra g-alpha-preirresolute and contra g-beta-preirresolute functions on generalized topological spaces. We give some examples of this definitions. ... -
Discontinuity at fixed points with applications
Pant, R. P.; Özgür, Nihal Yılmaz; Taş, Nihal (Belgian Mathematical Soc Triomphe, 2019)In this paper, we study new contractive conditions which are strong enough to generate fixed points but which do not force the map to be continuous at fixed points. In this context, we give new results on the fixed-circle ... -
Fixed discs in quasi-metric spaces
Aydi, Hassen; Taş, Nihal; Özgür, Nihal Yılmaz; Mlaiki, Nabil (House Book Science-Casa Cartii Stiinta, 2021)In this paper, we present some results of fixed disc and common fixed disc in quasi-metric spaces, under some very interesting contractions. Obtained results are supported by illustrative examples. -
Fixed-disc results on metric spaces
Taş, Nihal; Mlaiki, Nabil; Aydi, Hassen; Özgür, Nihal (Univ Nis, 2021)In this paper, we deal with the geometric properties of non-unique fixed points for self-mappings of a metric space (resp. an S-metric space). The fixed-disc (resp. fixed-circle) problem has been investigated in this ... -

A new coding/decoding algorithm using fibonacci numbers
Taş, Nihal; Uçar, Sümeyra; Özgür, Nihal Yılmaz; Kaymak, Öznur Öztunç (World Scientific Publ Co Pte Ltd, 2018)In this paper, we present a new method of coding/decoding algorithms using Fibonacci Q-matrices. This method is based on the blocked message matrices. The main advantage of our model is the encryption of each message matrix ... -
New complex-valued activation functions
Özgür, Nihal; Taş, Nihal (Balikesir University, 2020)We present a new type of activation functions for a complex-valued neural network (CVNN). A proposed activation function is constructed such that it fixes a given ellipse. We obtain an application to a complex-valued ... -
New contractive conditions of integral type on complete S-metric spaces
Özgür, Nihal Yılmaz; Taş, Nihal (Springer Heidelberg, 2017)An S-metric space is a three-dimensional generalization of a metric space. In this paper our aim is to examine some fixed-point theorems using new contractive conditions of integral type on a complete S-metric space. We ... -
