A multi‐pass method for accelerated spectral sampling [PDF]
Computer Graphics Forum, 2021 AbstractSpectral Monte Carlo rendering can simulate advanced light phenomena, such as chromatic dispersion, but typically shows a slow convergence behavior. Properly sampling the spectral domain can be challenging in scenes with many complex spectral distributions. To this end, we propose a multi‐pass approach.

Which Spectral Acceleration are you Using?
Earthquake Spectra, 2006Analysis of the seismic risk to a structure requires assessment of both the rate of occurrence of future earthquake ground motions (hazard) and the effect of these ground motions on the structure (response). These two pieces are often linked using an intensity measure such as spectral acceleration. However, earth scientists typically use the geometric

Estimate of spectral and pseudo-spectral acceleration proximity
Engineering Structures, 2008Abstract This paper deals with the deterministic relationship between spectral and pseudo-spectral acceleration, S A ( ξ , ω 0 ) and PS A ( ξ , ω 0 ) respectively, and gives the reason for their proximity on theoretical basis.

Spectral acceleration of the generalized forward-backward method [PDF]
IEEE Transactions on Antennas and Propagation, 2002 The generalized forward-backward (GFB) method was introduced as an iterative method of moments solution to compute the electromagnetic scattering from targets on ocean-like rough surfaces. In this paper, an existing spectral acceleration algorithm is adapted to the GFB.

Accelerating the convergence of spectral deferred correction methods [PDF]
Journal of Computational Physics, 2006 In the recent paper by Dutt, Greengard and Rokhlin, a variant of deferred or defect correction methods is presented which couples Gaussian quadrature with the Picard integral equation formulation of the initial value ordinary differential equation. The resulting spectral deferred correction (SDC) methods have been shown to possess favorable accuracy ...

Correlation in spectral accelerations for earthquakes in Europe
Earthquake Engineering & Structural Dynamics, 2012ABSTRACTThe shape of a uniform hazard spectrum has been criticized to be unrealistic for a site where the spectral ordinates of the uniform hazard spectrum at different periods are governed by different scenario events and conservative for long‐return‐period earthquake shaking.

Acceleration of spectral domain analysis method for conformal antennas
2010 International Workshop on Antenna Technology (iWAT), 2010This paper presents different approaches for acceleration of the spectral domain analysis of large conformal antennas and arrays. The basic idea is to find suitable simplification of the original problem that can be efficiently analyzed using alternative method like Uniform Theory of Diffraction (UTD).

Design spectra for damping ratios higher than 5% have several important applications in the design of earthquake-resistant structures. These highly damped spectra are usually derived from a 5%-damped reference pseudo-acceleration spectrum by using a damping modification factor.

Influence of Soil Softening and Liquefaction on Spectral Acceleration
Journal of Geotechnical and Geoenvironmental Engineering, 2005To provide design guidance on the influence of soil softening on ground response, we analyzed ground motions recorded at five instrumented liquefaction sites, including the Wildlife Liquefaction Array, Calif.; the Port Island Downhole Array, Japan, the Treasure Island and Alameda Naval Air Station sites, Calif., and the Kawagiahi-cho apartment ...

Estimation of spectral acceleration based on neural networks
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2014This study presents an effective method based on artificial intelligence to predict spectral acceleration from the data of the ‘Next generation attenuation' project. The proposed method uses the learning abilities of artificial neural networks to expand the knowledge of the mapping from earthquake parameters to spectral accelerations, which results in
