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 stockout situation. We construct a model to track the remaining raw materials in stock at the end of the first ... 
An application of soft set and fuzzy soft set theories to stock management
Taş, Nihal; Özgür, Nihal Yılmaz; Demir, Pelin (2017)Bu çalı¸smada stok durumlarının etkili bir ¸sekilde yönetimi probleminin çözümünde,esnek ve bulanık esnek kümelerin kullanılmasına ili¸skin bir uygulama verilmi¸stir. ?Ilk hafta(veya ilk ay) sonunda, esnek küme teorisinin ... 
Bilateraltype solutions to the fixedcircle problem with rectified linear units application
Taş, Nihal (Scientific Technical Research Council TurkeyTubitak, 2020)In this paper, we prove new fixedcircle (resp. fixeddisc) results using the bilateral type contractions on a metric space. To do this, we modify some known contractive conditions called the Jaggitype 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 complexvalued smetric 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, complexvalued Smetric spaces have been introduced and studied for this purpose. In this paper, we ... 
Common fixed points of continuous mappings on smetric 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 Smetric space. For this purpose, we prove new generalized common fixed point theorems using the notions of weak commutation, compatibility, and ... 
Contra galpha and gbetapreirresolute functions on GTS's
Açıkgöz, Ahu; Taş, Nihal; Sarsak, Mohammad S. (Springer Heidelberg, 2015)In this present paper, we define galphapreirresolute, gbetapreirresolute, contra galphapreirresolute and contra gbetapreirresolute 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 fixedcircle ... 
Fixeddiscs in rectangular metric spaces
Aydi, Hassen; Taş, Nihal; Özgür, Nihal Yılmaz; Mlaiki, Nabil (MDPI, 2019)In this manuscript, we present some results related to fixeddiscs of selfmappings in rectangular metric spaces. To do this, we give new techniques modifying some classical notions such as Banach contraction principle, ... 
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 Qmatrices. This method is based on the blocked message matrices. The main advantage of our model is the encryption of each message matrix ... 
New complexvalued activation functions
Özgür, Nihal; Taş, Nihal (Balikesir University, 2020)We present a new type of activation functions for a complexvalued neural network (CVNN). A proposed activation function is constructed such that it fixes a given ellipse. We obtain an application to a complexvalued ... 
New contractive conditions of integral type on complete Smetric spaces
Özgür, Nihal Yılmaz; Taş, Nihal (Springer Heidelberg, 2017)An Smetric space is a threedimensional generalization of a metric space. In this paper our aim is to examine some fixedpoint theorems using new contractive conditions of integral type on a complete Smetric space. We ...
