In recent years some multi-mode pushover procedures taking into account higher mode effects, have been proposed. The responses of considered modes are combined by the quadratic combination rules, while using the elastic modal combination rules in the inelastic phases is not valid. Here, an optimum weighted mode combination method for nonlinear static analysis is presented. Genetic algorithm is ...

A novel method was developed to separate the 238 U fission contribution measured in quasi-differential time-of-flight scattering experiments order isolate elastic and inelastic events. Pulse height distributions from in-beam measurements were used generate response functions, which reconstruct prompt neutron spectra. This validated by reconstructing 252 Cf spontaneous pulse distribution. Monte ...

  Abstract : The main objective of this study is estimating the strong motion for the Bam region using the stochastically based seismological models. The two widely used synthetic techniques namely point-source and finite-fault were utilized incorporating the source-path and site parameters into simple function. The decay factor kappa was estimated based on the data obtained from recorded stron...

In this report we address the problem of skin fluorescence in feature extraction from Raman spectra of skin lesions. We apply a highly automated neural network method for suppressing skin fluorescence from Raman spectrum of skin lesions before dimension reduction with principal components analysis. By applying the background suppression, the effect of outlier spectrum in the principal component...

We present recent results on elastic and inelastic low/medium energy electron interaction with tetrahydrofuran, C4H8O, tetrahydrofurfuryl alcohol, C5H10O2 and 3hydroxytetrahydrofuran, C4H8O2 molecules in gaseous phase. A comparative study of both absolute differential cross sections for elastic electron scattering and electron energy loss spectra, in a wide incident electron energy range from 5...

fiber metal laminates are hybrid laminates consisting of thin alternating bonded layers of aluminum and fiber/epoxy. arall (aramid aluminum laminate) and galare (glass fiber reinforced aluminum laminate) are specific kinds of fiber metal laminates that consist of thin aluminum sheets along with kevlar/epoxy and glass/epoxy composite layers, respectively. in this study, nonlinear tensile behavio...

Dynamics of the singlet-triplet crystalline electric field (CEF) system at finite temperatures is discussed by use of the non-crossing approximation. Even though the Kondo temperature is smaller than excitation energy to the CEF triplet, the Kondo effect appears at temperatures higher than the CEF splitting, and accordingly only quasi-elastic peak is found in the magnetic spectra. On the other ...

Several studies have been oriented to develop methodologies for estimating inelastic response of structures; however, the estimation of inelastic seismic response spectra requires complex analyses, in such a way that traditional methods can hardly get an acceptable error. In this paper, an Artificial Neural Network ANN model is presented as an alternative to estimate inelastic response spectra ...

We examine theoretically the effects of the bonding geometries at the gold-thiol interfaces on the inelastic tunneling spectra of propanedithiolate (PDT) molecules bridging gold electrodes and show that inelastic tunneling spectroscopy combined with theory can be used to determine these bonding geometries experimentally. With the help of density functional theory, we calculate the relaxed geome...
