Comparison of SVM and ANFIS for Snore Related Sounds Classification by Using the Largest Lyapunov Exponent and Entropy
(Computational and Mathematical Methods in Medicine, 2013)Snoring, which may be decisive for many diseases, is an important indicator especially for sleep disorders. In recent years, many studies have been performed on the snore related sounds (SRSs) due to producing useful results ... -
A Comparative Holistic Fuzzy Approach for Evaluation of the Chain Performance of Suppliers
(2014)The competition between the companies in the dynamic market conditions has made the Supply Chain Management (SCM) a more important issue. The companies which have organized their supply chain effectively have obtained more ... -
Anterior Kolon Kırığının İlioingunial Yaklaşım Tedavi Tekniği İle Medial Stoppa Tedavi Tekniğinin Biyomekanik Dayanımı Açısından Karşılaştırılması
(2014)Anterior kolon kırığı tedavisinde ilioinguinal yaklaşım altın standard olarak kullanılmaktadır. Medial stoppa tekniği ise pelvise ve asetabulumun medyal duvarına ulaşarak asetabulum kırıklarının tedavisinde kullanılan yeni ... -
Ölçeklenebilir Düzlemsel İletken Yapıların Karakteristik Açılım Fonksiyonu Yöntemi İle Geniş Bantta Analizi
(2014)Bu tez çalı¸smasında düzlemsel iletken cisimlerden geni¸s bir frekans bandında saçılma ve yayılma problemlerinin çözüm süresini kısaltacak bir yöntem geli¸stirilmi¸stir. Yöntemde bilinen karakteristik açılım fonksiyonları ... -
MCF-7 Kanser Hücrelerinin Antikor Tabanlı Mikrokanallar İçerisinde Yakalanması ve İncelenmesi
(2014)Kanser Dünya’da olduğu gibi Türkiye’de de ölümlerin başlıca sebebidir. Dünyadaki nüfus artışına ve nüfustaki yaşlanmaya bağlı olarak kanser artış hızı yükselmiştir. Uluslararası Kanser Ajansı özellikle meme kanserindeki ... -
A Self-Adaptive Heuristic Algorithm for Combinatorial Optimization Problems
(2014)This paper introduces a new self-tuning mechanism to the local search heuristic for solving of combinatorial optimization problems. Parameter tuning of heuristics makes them difficult to apply, as parameter tuning itself ... -
From static to rotating to conformal static solutions: rotating imperfect fluid wormholes with(out) electric or magnetic field
(2014)We derive a shortcut stationary metric formula for generating imperfect fluid rotating solutions, in Boyer-Lindquist coordinates, from spherically symmetric static ones. We explore the properties of the curvature scalar ... -
Regular and conformal regular cores for static and rotating solutions
(2014)Using a new metric for generating rotating solutions, we derive in a general fashion the solution of an imperfect fluid and that of its conformal homolog. We discuss the conditions that the stress-energy tensors and invariant ... -
Silhouette Extraction from Street View Images
(2014)This study addresses the issue of silhouette extraction of a street, and proposes two novel approaches to overcome this problem. The first, namely hybrid stitching considers the silhouette extraction as an image stitching ... -
An integrated simulation model for analysing electricity and gas systems
(2014)This paper aims at analysing the impacts of interdependencies between electricity and natural gas systems in terms of security of energy supply. When analysing both systems several interdependencies can be observed, however, ... -
Geometrothermodynamics: comments, criticisms, and support
(2014)We write explicitly the Euler identity and the Gibbs-Duhem relation for thermodynamic potentials that are not homogeneous first-order functions of their natural extensive variables. We apply the rules to the theory of ... -
Formulations for Minimizing Tour Duration of the Traveling Salesman Problem with Time Windows
(2015)Traveling Salesman Problem with Time Windows (TSPTW) serves as one of the most important variants of the Traveling Salesman Problem (TSP). The main objective functions expressed in the literature of the TSPTW consist of ... -
Charged de Sitter-like black holes: quintessence-dependent enthalpy and new extreme solutions
(2015)We consider Reissner-Nordstrom black holes surrounded by quintessence where both a non-extremal event horizon and a cosmological horizon exist besides an inner horizon (-1 = omega < - 1/3). We determine new extreme black ... -
Educating Future Energy Engineers for Sustainability: Case Study in Energy Economy
(2015)This paper analyzes the case study of an interdisciplinary course in Energy Economy that was developed at the Energy Engineering Graduate Program at Baskent University. The course integrated several unique pedagogical ... -
Transformation To Dual Physical Problems for The Visualization of Abstract Topics
(2015)The Abstract topics are often very difficult to be visualized for the undergraduate students in mathematics, physics and engineering. Those problems could be represented by four fundamental examples; basic vector algebra, ... -
Humoral immune response and coated or uncoated oxygenators during cardiopulmonary bypass surgery
(2016)Aim: To investigate and compare uncoated and phosphoryl-choline-coated oxygenators in terms of induction of humoral immune response during coronary artery bypass surgery. Methods: A total of 20 consecutive patients who ... -
