the objective of this paper is to determine the drift demand hazard curves of steel moment-resisting frames with different number of stories in territory of tehran this is done through the combination of the results obtained from probabilistic seismic hazard analysis and the demand estimated through the best probabilistic seismic demand models. to select the best demand model, in this paper, a ...

Multi-dimensional particle-in-cell simulations are used to study the generation of electrostatic shocks in plasma and the reflection of background ions to produce high-quality and high-energy ion beams. Electrostatic shocks are driven by the interaction of two plasmas with different density and/or relative drift velocity. The energy and number of ions reflected by the shock increase with increa...

Please cite this article in press as: Hwang E et a logic applications. Solid State Electron (2011), d In this paper, the scalability of In0.7Ga0.3As QWFET is investigated using two-dimensional numerical drift–diffusion simulation. Numerical drift–diffusion simulations were calibrated using experimental results on short-channel In0.7Ga0.3As QWFETs [7] to include the effects of velocity overshoot...

This paper presents the key design points of buckling-restrained braced frames (BRBFs) by using the performance-based plastic design (PBPD) methodology. This method is based on energy-work balance concept and uses pre-selected target drift and yield mechanism as design criteria. Based on multi-mode pushover and time-history analyses, a simple equation is developed for computing yield drift rati...

This paper examines the stock market reactions to US biotech firms’ innovation news announcements during 1983-1993. Besides the positive abnormal returns observed during the announcement period, the paper identifies a medium-horizon negative drift in the stock price subsequent to firms’ innovative events. The observed negative drift is robust to the benchmarks and procedures used in calculating...

We show that the continuous cholesteric fingers, which form in homeotropic samples at the unwinding temperature of the cholesteric phase, drift and spiral when they are subjected to a temperature gradient. This phenomenon is attributed to the appearance of a Lehmann thermomechanical torque. Measurements of the finger drift velocity on both sides of the compensation temperature of a cholesteric ...

Recent observations, reported by Warner and Woudt, of Dwarf Nova Oscillations (DNOs) exhibiting frequency drift, period doubling, and 1:2:3 harmonic structure, can be understood as disc oscillations that are excited by perturbations at the spin frequency of the white dwarf or of its equatorial layers. Similar quasi-periodic disc oscillations in black hole low-mass X-ray binary (LMXB) transients...

A new approach to signal processing of analytical time-domain data is presented. It consists in identifying the types of noise, characterizing them, and subsequently subtracting them from the otherwise unprocessed data set. The algorithms have been successfully applied to three classes of noise commonly found in analytical signals: spikes, ripples, and baseline drift. Traditional filters have b...

Using Langevin dynamics simulations, conformational, mechanical and dynamical properties of charged polymers threading through a nanopore are investigated. The shape descriptors display different variation behaviors for the cisand trans-side sub-chains, which reflects a strong cis-trans dynamical asymmetry, especially when the driving field is strong. The calculation of bond stretching shows ho...
