In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...

The problem of finding the minimum-energy configuration of particles on a lattice, subject to a generic short-ranged repulsive interaction, is studied analytically. The study is relevant to charge ordered states of interacting fermions, as described by the spinless Falicov–Kimball model. For a range of particle density including the half-filled case, it is shown that the minimum-energy states c...

Knowledge about the vertebrae is a valuable source of information for several annotation tasks. In recent years, the research community spent a considerable effort for detecting, segmenting and analyzing the vertebrae and the spine in various image modalities like CT or MR. Most of these methods rely on prior knowledge like the location of the vertebrae or other initial information like the man...

Figure-ground organization refers to the visual perception that a contour separating two regions belongs to one of the regions. Recent studies have found neural correlates of figure-ground assignment in V2 as early as 10-25 ms after response onset, providing strong support for the role of local bottom-up processing. How much information about figure-ground assignment is available from locally c...

The incident angle of ground motion is one of the sources of uncertainty in the seismic response of buildings. Moreover, understanding the structural response to the impose ground motion may cause significant changes in the maximum response of buildings. In order to investigate the effect of the spatial distribution of orthogonal components of earthquake strong motion on the structural response...

A formalism is presented for a novel fifth-order spectroscopy designed to measure the spectrum of nuclear modes coupled to photoinduced processes. In this description of polarizability response spectroscopy, a two-level system first interacts (twice) with an electronically resonant laser pulse to create ground and excited state wavepackets that evolve until the polarizability spectrum is probed...

A theorem for the invertibility of arbitrary response functions is presented under the following conditions: the time dependence of the potentials should be Laplace transformable and the initial state should be a ground state, though it might be degenerate. This theorem provides a rigorous foundation for all density-functional-like theories in the time-dependent linear response regime. Especial...

The Earthquake of January 26, 2001 of magnitude 7.6 on Richter scale has resulted in more than 25,000 fatalities and wide spread damage in India and SouthEast lower part of Sindh, Pakistan. The Intensity of this earthquake was felt from severe to minor near the epicenter and areas within 400 km radius. It has been reported that severe damage has occurred to mid to high-rise buildings in the cit...
