In the framework of probabilistic seismic hazard analysis, the preferred approach for obtaining the response spectrum of the vertical component of motion is to scale the horizontal spectrum by vertical-to-horizontal (V/H) spectral ratios. In order to apply these ratios to scenario or conditional mean spectra, the V/H ratios need to be defined as a function of variables such as magnitude, distance, and site classification. A new model for the prediction of V/H ratios for peak ground acceleration and spectral accelerations from 0.02 to 3.0 s is developed from the database of strong-motion accelerograms from Europe and the Middle East. A simple functional form, expressing the V/H ratios as a function of magnitude, style of faulting, distance, and site class, is found to be appropriate, and the associated aleatory variability is found to be at least as low as that obtained in other studies using more complex models. The predicted ratios from the new European model are found to be in broad agreement with recent models derived from predominantly western North America data.

Determination of jet energy calibration and transverse momentum resolution in CMS Chatrchyan, S.; et. al. (IOP Publishing, 2011-11-01) Measurements of the jet energy calibration and transverse momentum resolution in CMS are presented, performed with a data sample collected in proton-proton collisions at a centre-of-mass energy of 7TeV, corresponding to an integrated luminosity of 36p(-1). The transverse momentum balance in dijet and gamma/Z+jets events is used to measure the jet energy response in the CMS detector, as well as the transverse momentum resolution. The results are presented for three different methods to reconstruct jets: a ca...
An embedding technique to determine tau tau backgrounds in proton-proton collision data Sirunyan, A. M.; et. al. (IOP Publishing, 2019-06-01) An embedding technique is presented to estimate standard model ττ backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed μμ events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique...
A composite pulsating controller for achieving high-performance positioning Tufekci, C. S.; Craig, K. C. (SAGE Publications, 2012-02-01) A non-linear robust control algorithm called a composite pulsating controller (CPC), which attains high-performance positioning specifications, is presented. The CPC is designed specifically for real product applications that have certain limitations such as friction, motor sizing, amplifier saturation, computational power and like. The CPC is composed of a bang-bang controller, a nominal proportional-integral-derivative (PID) controller, a high-gain PID controller and a pulsating controller in accomplishin...
A short cut numerical method for determination of periods of free oscillations for basins with irregular geometry and bathymetry Yalçıner, Ahmet Cevdet (Elsevier BV, 2007-04-01) A short cut numerical method for evaluation of the modes of free oscillations of the basins which have irregular geometry and bathymetry is presented in this paper. In the method, a single wave is inputted to the basin as an initial impulse. The respective agitation in the basin is computed by using the numerical method solving the nonlinear form of long wave equations. The time histories of water surface fluctuations at different locations due to propagation of the waves in relation to the initial impulse ...
A Numerical Simulation of non-uniform Magnetic Field Effect on Ferrofluid Flow in a Half-Annulus Enclosure with Sinusoidal Hot Wall Oglakkaya, F. S.; Bozkaya, Canan (2016-09-25) In this study, the problem of two-dimensional, laminar ferrofluid flow in a semi-annulus enclosure with sinusoidal hot wall is investigated numerically by using the dual reciprocity boundary element method. The flow is under the influence of a nodal magnetic source placed below the mid of the sinusoidal inner wall. The equations governing the present problem are obtained under the principles of ferrohydrodynamics and magnetohydrodynamics. The numerical computations are performed for various values of Raylei...
