A sub-sampling pulse-resonance OOK modulated digital ultrasound communication system for biomedical IoT
(Elsevier, 2019-11-01)A pulse-resonance On-Off keying ultrasound communication microsystem is presented. It is a viable alternative to today's widely used RF technologies in order to avoid the associated health risks for a specific group of ... -
Subcooled flow boiling heat transfer of γ-Al2O3/water nanofluids in horizontal microtubes and the effect of surface characteristics and nanoparticle deposition
(Elsevier, 2017)In this study, subcooled flow boiling heat transfer characteristics of nanofluids were investigated at micro scale. For this purpose, the effect of γ-Al2O3 (gamma-alumina) nanoparticles with an average solid diameter of ... -
Subdiffusivity of brownian motion among a poissonian field of moving traps
(Instituto Nacional de Matematica Pura e Aplicada, 2019)Our model consists of a Brownian particle X moving in N, where a Poissonian field of moving traps is present. Each trap is a ball with constant radius, centered at a trap point, and each trap point moves under a Brownian ... -
Subjective bayesian networks and human-in-the-loop situational understanding
(Springer, 2018-03-21)In this paper we present a methodology to exploit human-machine coalitions for situational understanding. Situational understanding refers to the ability to relate relevant information and form logical conclusions, as well ... -
Successive refinement of models for model-based testing to increase system test effectiveness
(IEEE, 2016)Model-based testing is used for automatically generating test cases based on models of the system under test. The effectiveness of tests depends on the contents of these models. Therefore, we introduce a novel three-step ... -
A suite of broadband physics-based ground motion simulations for the Istanbul region
(Wiley, 2023-04)Physics-based earthquake ground motion simulations (GMS) have acquired significant growth over the last two decades, mainly due to the explosive developments of high-performance computing techniques and resources. These ... -
Summary of an effective formulation of the multi-criteria test suite minimization problem
(IEEE, 2022)This is an extended abstract of the article: Okan Orsan Ozener and Hasan Sozer, 'An Effective Formulation of the Multi-Criteria Test Suite Minimization Problem', published in the Journal of Systems and Software, Vol. 168, ... -
Supervising topic models with Gaussian processes
(Elsevier, 2018-05)Topic modeling is a powerful approach for modeling data represented as high-dimensional histograms. While the high dimensionality of such input data is extremely beneficial in unsupervised applications including language ... -
Supplier selection and order allocation in the presence of suppliers with exact annual capacity
(Inderscience Enterprises Ltd., 2021)In this paper, we focus on the supplier selection and order quantity allocation for a single retailer. The retailer orders a product from multiple suppliers with capacities, adds value to the product and fulfils the demand ... -
Supplier selection for framework agreements in humanitarian relief
(Wiley, 2014-06)In this study, we consider the supplier selection problem of a relief organization that wants to establish framework agreements (FAs) with a number of suppliers to ensure quick and cost-effective procurement of relief ... -
Suppression and azimuthal anisotropy of prompt and nonprompt J/psi production in PbPb collisions at root S-NN=2.76 TeV
(Springer International Publishing, 2017-04)The nuclear modification factor R-AA and the azimuthal anisotropy coefficient v(2) ofprompt and nonprompt (i.e. those from decays of b hadrons) J/psi mesons, measured from PbPb and pp collisions at root S-NN = 2.76 rfeV ... -
Suppression of excited Υ states relative to the ground state in Pb-Pb collisions at √sNN =5.02 TeV
(American Physical Society, 2018-04-02)The relative yields of gamma mesons produced in pp and Pb-Pb collisions at root s(NN) = 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are ... -
Suppression of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states in PbPb collisions at √sNN = 2.76 TeV
(Elsevier, 2017)The production yields of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states are measured through their decays into muon pairs in the CMS detector, in PbPb and pp collisions at the centre-of-mass energy per nucleon pair of 2.76 ... -
Surface characterization driven CMP optimization for gallium nitride
(ECS, 2016)Gallium nitride is a hard and chemically inert material demoting high material removal rates in the chemical mechanical planarization (CMP) applications. This paper focuses on the optimization of the process conditions to ... -
Surface characterization of textiles for optimization of functional polymeric nano-capsule attachment
(Carl Hanser Verlag, 2019-09)Surface properties of textiles play an essential role in their functionalization with micro/nanometer-sized polymeric capsules containing active agents that can provide controlled release. The attached capsules provide ... -
Surface waves and atomic force microscope probe-particle near-field coupling: discrete dipole approximation with surface interaction
(Optics InfoBase, 2010-10)Evanescent waves on a surface form due to the collective motion of charges within the medium. They do not carry any energy away from the surface and decay exponentially as a function of the distance. However, if there is ... -
Surfactant mediated slurry formulations for Ge CMP applications
(Cambridge University Press, 2013)In this study, slurry formulations in the presence of self-assembled surfactant structures were investigated for Ge/SiO2 CMP applications in the absence and presence of oxidizers. Both anionic (sodium dodecyl sulfate-SDS) ... -
A survey of adjustable robust optimization
(Elsevier, 2019-09)Static robust optimization (RO) is a methodology to solve mathematical optimization problems with uncertain data. The objective of static RO is to find solutions that are immune to all perturbations of the data in a so-called ...
