Landfill Gas to the Energy Potential of Turkey: A Scenario-based Multi-period Simulation
(Taylor & Francis Inc, 2013)Turkey is a developing country with increasing power demands and limited energy sources. Municipal solid waste processing landfilling and utilization of the gas to generate electric power and lower emissions has been used ... -
Large Eddy Simulation of Wind Flow over A Realistic Urban Area
(MDPI, 2020)A high-resolution large eddy simulation (LES) of wind flow over the Oklahoma City downtown area was performed to explain the effect of the building height on wind flow over the city. Wind flow over cities is vital for ... -
'Level grading' a new graded algebra structure on differential polynomials: application to the classification of scalar evolution equations
(IOP Publishing Ltd, 2013)We define a new grading which we call the 'level grading' on the algebra of polynomials generated by the derivatives u(k+i) over the ring K-(k) of C-infinity functions of x t u u(1) ... u(k) where . This grading has the ... -
Managing Fuel Coal Supply Chains With Multiple Objectives and Multimode Transportation
(AMER SOC ENGINEERING MANAGEMENT, 2013)Power companies require sophisticated tools to manage fuel-coal supply chains which include multiple suppliers coal contracts and multimode transportation routes. In this article a multi-objective model which is integrated ... -
Managing natural gas demand for free consumers under uncertainty and limited storage capacity
(Elsevier, 2020)Demand for energy sources depends on several factors such as population growth, urbanization, industrialization, and climate. Among fundamental energy sources, natural gas is characterized by storage limitations and ... -
Markov-modulated analysis of a spare parts system with random lead times and disruption risks
(Elsevier Science Bv, 2018)Spare parts supply chains are highly dependent on the dynamics of their installed bases. A decreasing number of capital products in use increases the nonstationary supply-side risk especially towards the end-of-life of ... -
Master problem approximations in Dantzig-Wolfe decomposition of variational inequality problems with applications to two energy market models
(Pergamon-Elsevier Science Ltd, 2013)In this paper a modification to Dantzig-Wolfe (DW) decomposition algorithm for variational inequality (VI) problems is considered to alleviate the computational burden and to facilitate model management and maintenance. ... -
A mathematical characterization of the gel point in sol-gel transition
(IOP Publishing Ltd, 2015)We model the sol-gel transition in terms of Susceptible-Infected-Removed (SIR) and Susceptible-Exposed-Infected-Removed (SEIR) models and compare with experimental results. We show, numerically, that the "gel point" described ... -
Mathematical Characterization of Thermo-reversible Phase Transitions of Agarose Gels
(Taylor & Francis Inc, 2018)The thermal phase transition temperatures of high (HMP) and low melting point (LMP) agarose gels were investigated by using UV-vis spectroscopy techniques. Transmitted light intensities from the gel samples with different ... -
A MATHEMATICAL DESCRIPTION OF THE CRITICAL POINT IN PHASE TRANSITIONS
(World Scientific Publ Co Pte Ltd, 2013)Let y(x) be a smooth sigmoidal curve, y((n)) be its nth derivative and {x(m,i)} and {x(a,i)}, i = 1, 2, ... , be the set of points where respectively the derivatives of odd and even order reach their extreme values. We ... -
Maximal linear subspaces of strong self-dual 2-forms and the Bonan 4-form
(Elsevier Science Inc, 2011)The notion of self-duality of 2-forms in 4-dimensions plays an eminent role in many areas of mathematics and physics, but although the 2-forms have a genuine meaning related to curvature and gauge-field-strength in higher ... -
A memetic random-key genetic algorithm for a symmetric multi-objective traveling salesman problem
(Pergamon-Elsevier Science Ltd, 2008)This paper proposes a methodology to find weakly Pareto optimal solutions to a symmetric multi-objective traveling salesman problem using a memetic random-key genetic algorithm that has been augmented by a 2-opt local ... -
Metalization of polymer beads via polymer-supported hydrazines as reducing agents
(John Wiley & Sons Inc, 2002)A new method for depositing metal onto a polymer surface has been developed in which the metal coating of polymer beads is performed with hydrazine functions as reducing agents on the surface of the polymer itself. In this ... -
Minimization of rest mismatches in round robin tournaments
(Pergamon-Elsevier Science Ltd, 2018)In sports tournaments an occurrence of a difference in the rest periods of opponent teams in a game which we refer to as a rest mismatch will disadvantage the less rested team. Thus it is only fair to expect opposing teams ... -
Modeling of Wind Effects on Stratified Flows in Open Channels: A Model for the Istanbul Strait (Bosphorus)
(2016)Stratified flows in open channels arise as a result of density or surface level differences. If the channel is connected to a basin at one or both ends, strong winds originating from the basin cause the "wind setup" effect ... -
Models for relief routing: equity efficiency and efficacy
(Pergamon-Elsevier Science Ltd, 2012)In humanitarian relief operations vehicle routing and supply allocation decisions are critically important. Similar routing and allocation decisions are studied for commercial settings where efficiency in terms of minimizing ... -
Multi-objective Fuel Supply for Coal-fired Power Plants Under Emission Transportation and Operational Constraints
(Taylor & Francis Inc, 2013)Coal-fired power plants need to decrease their generation cost in deregulated power markets so as to be selected dispatched and compete with other cheaper resources. On the other hand coal prices have risen significantly ... -
A multi-objective mathematical model for the industrial hazardous waste location-routing problem
(Elsevier Science Bv, 2013)Industrial hazardous waste management involves the collection transportation treatment recycling and disposal of industrial hazardous materials that pose risk to their surroundings. In this paper a new multiobjective ... -
