Age-based vs. stock level control policies for a perishable inventory system
(2001)In this study, we investigate the impact of modified lotsize-reorder control policy for perishables which bases replenishment decisions on both the inventory level and the remaining lifetimes of items in stock. We derive ... -
Anisotropy sensitivity of an acoustic lens with slit aperture
(IEEE, 1993)A conventional spherical acoustic lens is modified by restricting its aperture in the form of a slit to provide directional sensitivity. The spacing between the two parallel absorbing sheets forming the slit is adjustable ... -
Bi-angular lens for material characterization
(IEEE, 1994)In this paper a new lens design is proposed for characterization of layered materials. Lamb wave lens employs Lamb waves for this purpose since these waves propagate along interfaces. However, below cut-off angle, the ... -
Bounds on the opportunity cost of neglecting reoptimization in mathematical programming
(INFORMS, 2000)Postoptimality or sensitivity analysis are well-developed subjects in almost all branches of mathematical programming. In this note, we propose a simple formula which can be used to get preliminary bounds on the value of ... -
Concept of T-wave morphology dispersion
(IEEE, 1999)The detection of ventricular repolarization abnormalities is widely being done using the QT interval measurements. However, there are both technical and theoretical problems with QT measurements. We propose two robust ... -
Cytotoxic activity of resveratrol in different cell lines evaluated by MTT and NRU assays
(Turkish Pharmacists Association, 2016)Oxidative stress is the state of imbalance between the level of antioxidant defence system and production of reactive oxygen species (ROS) and is involded in the progression of several diseases such as inflammation, cancer, ... -
The effect of continuous price change in the EOQ
(Pergamon Press, 1992)The sensitivity of the basic economic order quantity (EOQ) model to continuous purchase price changes is explored. The phenomenon of continuous price changes exists in several countries and it is not likely to improve. The ... -
Experimental results for 2D magnetic resonance electrical impedance tomography (MR-EIT) using magnetic flux density in one direction
(Institute of Physics Publishing, 2003)Magnetic resonance electrical impedance tomography (MR-EIT) is an emerging imaging technique that reconstructs conductivity images using magnetic flux density measurements acquired employing MRI together with conventional ... -
A gPC-based approach to uncertain transonic aerodynamics
(2010)The present paper focus on the stochastic response of a two-dimensional transonic airfoil to parametric uncertainties. Both the freestream Mach number and the angle of attack are considered as random parameters and the ... -
A Hamiltonian-based solution to the mixed sensitivity optimization problem for stable pseudorational plants
(Elsevier, 2005-11)This paper considers the mixed sensitivity optimization problem for a class of infinite-dimensional stable plants. This problem is reducible to a two- or one-block H∞ control problem with structured weighting functions. ... -
A highly sensitive atomic force microscope for linear measurements of molecular forces in liquids
(American Institute of Physics, 2005)We describe a highly improved atomic force microscope for quantitative nanomechanical measurements in liquids. The main feature of this microscope is a modified fiber interferometer mounted on a five axis inertial slider ... -
Highly sensitive determination of 2, 4, 6-trinitrotoluene and related byproducts using a diol functionalized column for high performance liquid chromatography
(Public Library of Science, 2014)In this work, a new detection method for complete separation of 2,4,6-trinitrotoluene (TNT); 2,4-dinitrotoluene (2,4-DNT); 2,6-dinitrotoluene (2,6-DNT); 2-aminodinitrotoluene (2-ADNT) and 4-aminodinitrotoluene (4-ADNT) ... -
The impact of democracy and media freedom on under-5 mortality, 1961–2011
(Elsevier Ltd, 2017)Do democracies produce better health outcomes for children than autocracies? We argue that (1) democratic governments have an incentive to reduce child mortality among low-income families and (2) that media freedom enhances ... -
Influence function based Gaussianity tests for detection of microcalcifications in mammogram images
(IEEE, 1999-10)In this paper, computer-aided diagnosis of microcalcifications in mammogram images is considered. Microcalcification clusters are an early sign of breast cancer. Microcalcifications appear as single bright spots in mammogram ... -
Integrated micro ring resonator displacement sensor for scanning probe microscopies
(Institute of Physics Publishing, 2004)We describe a novel displacement sensor for scanning probe microscopies using an integrated optical micro ring resonator. This device operates by means of monitoring the changes in the transmission spectrum of a high finesse ... -
Investigation and comparison of the preprocessing algorithms for microarray analysis for robust gene expression calculation and performance analysis of technical replicates
(IEEE, 2006)Preprocessing of microarray data involves the necessary steps of background correction, normalization and summarization of the raw intensity data obtained from cDNA or oligo-arrays before statistical analysis. Several ... -
Investigation on sources of growth for Turkey
(Routledge, 2006)This paper evaluates the correlations between growth and selected macroeconomic indicators in, Turkey under the dynamic macroeconomic adjustments as a globalizing developing economy during 1968-1998. In this context, a ... -
Locating temporary shelter areas after an earthquake: a case for Turkey
(Elsevier, 2015)In this study, we propose a mixed integer linear programming based methodology for selecting the location of temporary shelter sites. The mathematical model maximizes the minimum weight of open shelter areas while deciding ... -
Location and curvature estimation of spherical targets using multiple sonar time-of-flight measurements
(Institute of Electrical and Electronics Engineers, 1999-12)A novel, flexible, three-dimensional multisensor sonar system is described to localize the center of a generalized spherical target and estimate its radius of curvature. Point, line, and planar targets are included as ... -
A maintanence policy for a system with multi-state components: an approximate solution
(Elsevier, 2002)For maintenance and quality assessment purposes, various performance levels for both systems and components are identified, usually as a function of the deterioration. In this study, we consider a multicomponent system ...
