The Location-Routing Problem with Simultaneous Pickup and Delivery: Formulations and A Heuristic Approach
(2012)In this paper, we consider a variant of the Location-Routing Problem (LRP), namely the LRP with simultaneous pickup and delivery (LRPSPD). The LRPSPD seeks to minimize total cost by simultaneously locating the depots and ... -
New Integer Linear Programming Formulation for the Traveling Salesman Problem with Time Windows: Minimizing Tour Duration with Waiting Times
(2013)The travelling salesman problem, being one of the most attractive and well-studied combinatorial optimization problems, has many variants, one of which is called travelling salesman problem with Time Windows (TSPTW)'. In ... -
Driver Performance Appraisal Using GPS Terminal Measurements: A Conceptual Framework
(2013)Objective measurement for performance appraisal is vital but rarely conducted in a methodologically sound manner. In this paper, we provide a thorough assessment of how objective and fair performance appraisals of drivers ... -
Development of A Decision Support System for Robot Selection
(2013)With the availability of more different robot types and models along with their separate specifications, selecting the most appropriate robot is becoming more difficult and complicated for companies. Furthermore, a common ... -
Crew Pairing Optimization Based On Hybrid Approaches
(2013)The crew pairing problem (CPP) deals with generating crew pairings due to law and restrictions and selecting a set of crew pairings with minimal cost that covers all the flight legs. In this study, we present three different ... -
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 ... -
Are Preformed Cooper Pairs The Cause For The Pseudogap in Superconductors?
(2014)A weak-coupling scenario wherein bosonic preformed electron pairs emerge upon cooling from two-electron correlations can explain the pseudogap phase consisting of segments where a Bogoliubov-like energy-momentum relation ... -
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, ... -
An Exergetic Approach to The Age of Universe
(2014)Recent finding by Bond et al. (2013) about the age of the star HD 140283 (14.46 +/- 0.8 Gyr) requires us to reconsider the estimates about the age of the universe, namely 13.817 +/- 0.048 Gyr. Their conflicting result is ... -
Solution of Linear Differential Equations with Fuzzy Boundary Values
(2014)We investigate linear differential equations with boundary values expressed by fuzzy numbers. In contrast to most approaches, which search for a fuzzy-valued function as the solution, we search for a fuzzy set of real ... -
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 ... -
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 ... -
Solution to Al-Jurjani's 1,000 Year Old Signal Processing Problem on The Generation of Harmonics in Music
(2014)Interval (tuning) systems in music reflect history, culture and geography. The classical music of the west is based on the twelve-tone equal temperament (12-TET) interval (tuning) system which became dominant throughout ... -
Feature Extraction For Musıc Signals: Just Tuned, Equal Temperament And Intense Diatonic Systems
(2014)Feature extraction of music signals are often required in applications including; identification and classification of music files over the web or a database. The feature observations for different classes are expected to ... -
Generation of Quasi-Random Numbers with Exact Statistics
(2014)System models are generally developed for predicting the outcome of the system under test due to a preset input. This is true not only for problems in mathematics, physics and engineering but also for problems in economics, ... -
Just-37 Interval System - A Complete Set of Natural Harmonics For Turkish Maqams
(2014)Identification and classification of music signals provide solutions for multi-media applications including categorized data sharing over the web. The mathematical analysis of music requires features for discriminating; ... -
Randomness Tests For The Method Of Unıform Sampling Quasi-Random Number Generator (MUS-QRNG)
(2014)Random number generation is still an important research field in many scientific applications today. Cryptography, Monte Carlo simulations and commertial applications all rely on reference random data. Randomness tests and ...
