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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
Wormhole solutions sourced by fluids, I: Two-fluid charged sources
(2016)We briefly discuss some of the known and new properties of rotating geometries that are relevant to this work. We generalize the analytical method of superposition of fields, known for generating nonrotating solutions, and ... -
Wormhole solutions sourced by fluids, II: three-fluid two-charged sources
(2016)Lack of a consistent metric for generating rotating wormholes motivates us to present a new one endowed with interesting physical and geometrical properties. When combined with the generalized method of superposition of ... -
Engineering long shelf life multilayer biologically active surfaces on microfluidic devices for point of care applications
(2016)Although materials and engineered surfaces are broadly utilized in creating assays and devices with wide applications in diagnostics, preservation of these immuno-functionalized surfaces on microfluidic devices remains a ... -
Hybridizing a fuzzy multi-response Taguchi optimization algorithm with artificial neural networks to solve standard ready-mixed concrete optimization problems
(2016)In this study, a fuzzy multi-response standard ready-mixed concrete (SRMC) optimization problem is addressed. This problem includes two conflicting quality optimization objectives. One of these objectives is to minimize ...
