On computer-aided prognosis of septic shock from vital signs
(2019)Sepsis is a life-threatening condition due to the reaction to an infection. With certain changes in circulatory system, sepsis may progress to septic shock if it is left untreated. Therefore, early prognosis of septic shock ... -
A New Motion Model Selection Approach for Multi-Model Particle Filters
(2019)One of the important factors in real-time tracking of the moving radar targets is the speed of the algorithm. In the multi-model particle filters (WPFs) which is frequently preferred tracking of such targets, the numbers ... -
Occupational health and safety performance evaluation of countries based on MAIRCA
(2019)Purpose The purpose of this paper is to develop an approach to compare occupational health and safety (OHS) performances of countries. Additionally, another aim is to debate the impacts of using recorded data and ratios ... -
An electrochemically and optically stable electrochromic polymer film based on EDOT and 1,2,3,4-tetrahydrophenazine
(2019)In this work, 3,4-ethylenedioxythiophene (EDOT) and 1,2,3,4-tetrahydrophenazine based donor-acceptor-donor type monomer (EBE) was synthesized, electropolymerized and the resulting polymer film (P(EBE)) was investigated in ... -
Evaluation of Flexibility Capacity in Pediatric Overweight
(2019)Childhood is a severe threat to human health. There is a suggested relationship between overweight and physical fitness. The aim of the present study is to determine the association between overweight and flexibility in ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ...
