Bu çalışma, sigortalı biriktirme modellemesi (eritmeli yığma modeli) yöntemine dayalı olarak sade, şık ve kartezyen tipinde üç boyutlu bir yazıcı tasarım ve üretiminin yapılması ile ilgilidir. Yapılan yazıcı modellemesinde, poliaktik asit plastik malzemesi, yü…

Korovkin type approximation theorems have very important role in the approximation theory. Many mathematicians investigate and improve these type of approximation theorems for various operators defined on different spaces via several new convergence methods. T…

Many researchers have been interested in the concept of statistical convergence. Since statistical convergence is stronger than the classical convergence. Then, F. Móricz has introduced the statistical convergence of double sequences (Arch. Math. 81 no.1, 82-8…

Robot algorithms require faster and more efficient computing due to increasing integration of robot arms to automation systems and expanding capabilities of robotic systems. Inverse kinematics calculations used in trajectory generation is one of these algorith…

The Korovkin theory has effective role in approximation theory. This theory is connected with the approximation to continuous functions by means of positive linear operators. Many mathematicians have investigated the Korovkin-type theorems by for a sequence of…

Coupled fixed point results for nonlinear contraction mappings having a mixed monotone property in a partially ordered G-metric space due to Choudhury and Maity are extended and unified. In this paper, some corresponding coupled fixed point theorems are obtain…

Classical approximation theory has started with the proof of Weierstrass approximation theorem and after that Korovkin [Linear operators and approximation theory, Hindustan Publ. Corp, Delhi, 1960] first established the necessary and sufficient conditions for …

It is important to determine the initial level of failures of induction motors used in many industrial applications. The sudden stops of the system can be prevented with the pre-detection of the fault. The experiment mechanism was established to detect mechani…

Uyku bozuklukları toplumda yaygın olarak görülen bir halk sağlığı sorunudur. Uyku; zaman, ışık, beslenme gibi birçok çevresel faktörden etkilenen 24 saatte bir tekrar eden sirkadiyen ritmin önemli bir parçasıdır. Uyku bozuklukları; İnsomnia [kronik uykusuzluk]…

The aim of this study was to investigate how melatonin administration  diabetic elderly female  rats affects the levels of bone tissue SIRT1. The study was performed on female aged rats (16 months old) who were provided by The Experimental Medicine Research an…

In 2008 Suzuki introduced C-condition for mappings which defined  on a subset of a Banach space and presented fixed point theorems. And in 2010 Khan and Suzuki gave a reich type convergence theorem for generalized nonexpansive mappings in uniformly convex Bana…

The devices developed in the field of organic electronics in recent years are on the technological applications and development of organic electronic devices using organic semiconductor films. The main applications of the organic electronic revolution are; Ele…

It is a fact that countries with robust and inclusive health services have a longer life expectancy at birth. Health services aim to improve and maintain health. In order to achieve these objectives, an integrated combination of various activities in which the…

Fotovoltaik (FV) sistemler birkaç W’dan, MW’a kadar ölçeklendirilebilmesi gibi özelliklerinden dolayı en çok yaygınlaşan yenilenebilir enerji kaynağı türüdür. Bu enerji kaynağından en yüksek oranda yararlanılabilmesi maksimum güç noktasını izleyen (MPPT) dönüş…

In this study, chicken and ground beef samples purchased from supermarkets and butchers in Samsun Province were analyzed for presence of Pseudomonas (P.) aeruginosa. In this case, classical culture technique were applied with molecular techniques. Isolation wa…

The aim of this study was to investigate the effects of melatonin administraton on bone tissue damage  in a diabetic elderly female rat model. The study was performed on female aged rats (16 months old) who were provided by The Experimental Medicine Research a…

Türkiye’de tüketim harcamaları içerisinde en fazla payı gıda ve alkolsüz içecek sektörü (%24.45) almaktadır. Bu kapsamda, böylesine önemli bir sektörde tüketici davranışları oldukça önem arz etmektedir.  Bu bağlamda çalışmada, içecek tüketim harcamalarında etk…

Korku, insanın kendi düşüncelerinden kaynaklanan bir duygudur. İnsanoğlunun beklenmedik ve öngörülmeyen bir durum karşısında zihninin yoğunlaşmasını sağlayan bir mekanizmadır. Bu duygunun ortaya çıkmasının nedeni, tehlike düşüncesinin uyandırdığı duygusal reak…

A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…

The study of various mathematical problems (such as elasticity, non-Newtonian fluids and electrorheological fluids) with variable exponent growth condition has been received considerable attention in recent years. These problems are interesting in applications…
