Aircraft Structural Safety : Effects of Explicit and Implicit Safety and Measures Uncertainty Reduction Mechanisms
(University of Florida, 2006)Aircraft structural safety is achieved by using different safety measures such as safety and knockdown factors, tests and redundancy. Safety factors or knockdown factors can be either explicit (e.g., load safety factor of ... -
Comparison of Bayesian Estimation and Neural Network Model in Stock Market Trading
(ASME Press, 2008)In this study, a decision support system for stock market prediction is proposed. This model uses the historical data of 180K data points obtained from the 215 highest volume ETFs that are open for trade in NYSE. The data ... -
Hardgrove Grindability Index Estimation Using Neural Networks
(2008)In a previous study, different techniques for the estimation of coal HGI values were investigated (Özbayoğlu et.al, 2008). As continuation of that research, in this study a revised neural network methodology is used for ... -
The frictional contact problem of sliding rigid parabolic stamps on graded materials
(2008-02)This study presents an analytical procedure to determine the contact stress distribution at the surface of an FGM coating perfectly bonded to a homogeneous substrate. The coating is assumed to be loaded by a rigid stamp ... -
Stock Market Technical Indicator Optimization by Genetic Algorithms
(ASME Press, 2010)Technical indicators are widely used in stock market forecasting, mostly to trigger the buy/sell rules in the technical analysis. Through some statistical analysis some key values for several indicator parameters are ... -
Mesoscopic nonequilibrium thermodynamics treatment of the grain boundary thermal grooving induced by the anisotropic surface drift diffusion
(Springer, 2011-09)A systematic study based on the self-consistent dynamical simulations is presented for the grain boundary thermal grooving problem by strictly following the irreversible thermodynamic theory of surfaces and interfaces with ... -
Grain boundary grooving in bi-crystal thin films induced by surface drift-diffusion driven by capillary forces and applied uniaxial tensile stresses
(Taylor & Francis Ltd, 2012)Grain boundary (GB) grooving, induced by surface drift-diffusion and driven by the combined actions of capillary forces and applied uniaxial tensile stresses, is investigated in bi-crystal thin films using self-consistent ... -
Peptides to bridge biological-platinum materials interface
(Ice Publishing, 2012)Peptides with inorganic materials recognition already started to impact a wide range of surface- related technologies ranging from biomonitoring to biomedical areas. Combinatorial biology- based libraries are the initial ... -
Dynamic server allocation for unstable queueing networks with flexible servers
(Springer, 2012-01)This paper is concerned with the dynamic assignment of servers to tasks in queueing networks where demand may exceed the capacity for service. The objective is to maximize the system throughput. We use fluid limit analysis ... -
A criterion for the onset of void coalescence under combined tension and shear
(Pergamon-Elsevier Science Ltd, 2012-07)Depending on the relative positions of voids and on the loading conditions, shear loading components can play an important role in the void coalescence process leading to ductile fracture. Yet, most void coalescence criteria ... -
Comparison of Gross Calorific Value Estimation of Turkish Coals using Regression and Neural Networks Techniques
(Metso,Vale,Tata Steel,ESSAR STEEL,TATA CONSULTANCY SERVICE, 2012-09)Gross calorific value (GCV) of coals was estimated using artificial neural networks, linear and non- linear regression techniques. Proximate and ultimate analysis results were collected for 187 different coal samples. ... -
Modification of Quartz Crystal Microbalance Surfaces via Electrospun Nanofibers Intended for Biosensor Applications
(American Scientific Publishers, 2013-04)The major aim of this study is to increase the performance of mass sensitive biosensor surfaces by making modifications on quartz crystal microbalance (QCM) surfaces via electrospinning and plasma polymerization techniques. ... -
Effects of the correlation model, the trend model, and the number of training points on the accuracy of Kriging metamodels
(Wiley-Blackwell, 2013-11)This paper explores the effects of the correlation model, the trend model, and the number of training points on the accuracy of Kriging metamodels. Gaussian correlation models are found to be superior to exponential and ... -
Ceruloplasmin and catalase activites in pseudoexfoliation syndrome and pseudoexfoliation glaucoma
(Türkiye Klinikleri, 2013-11)Objective: Pseudoexfoliation syndrome (PEX) is an age-related systemic disorder primarily with ocular manifestations. PEX is considered as the most common identifiable cause of glaucoma (pseudoexfoliation glaucoma, PEG) ... -
Plasma Modified Membrane for Daily Recovery of Oil from Repeated Frying Operation with Frequent Oil Replenishment
(Springer, 2013-11)Sunflower oil was used for deep frying of potatoes at 170 +/- A 5 A degrees C and for 8 h per day for 5 days in a fryer with an automatic oil filtration system. Three different frying operations were performed: operation ... -
Reliability prediction through guided tail modeling using support vector machines
(Sage Publications Ltd, 2013-12)Reliability prediction of highly safe mechanical systems can be performed using classical tail modeling. Classical tail modeling is based on performing a relatively small number of limit-state evaluations through a sampling ... -

(Springer, 2013-12)This study focuses on the utilization of glow discharge technique for the reduction of microorganisms on food contacting surfaces to determine whether non-thermal, low-pressure plasma could provide an effective alternative ... -
The Impact of Random Power Assignment in Handshaking on Wireless Sensor Network Lifetime
(IEEE, 2014)Optimization of data and acknowledgement (ACK) packets' transmission power levels is necessary to prolong the lifetime of wireless sensor networks (WSNs). Utilizing the maximum power level available results in the minimum ... -
Spectrum Sharing in Radar and Wireless Communication Systems: A Review
(IEEE, 2014)The idea of spectrum sharing between radar and wireless communication systems arise because of the need for extra bandwidth for wireless communication systems. Due to strong and ever growing economic, political, social, ...
