This study aims at determining the critical seismic intensity at which cracks are expected to develop in a concrete arch dam. This intensity is referred to as crack initiation intensity. The crack initiation intensity measure implies that earthquakes with the intensity measure higher than this value are expected to induce cracks in the arch dam. This quantity is an indicator for seismic evaluat...

The authors have studied the excitation-dependent optical properties of GaN/AlN self-assembled quantum dots QDs grown on Si 111 substrates. Ensembles of QDs were subject to various external stress configurations that resulted from the thermal expansion coefficient mismatch between the GaN/AlN layers and the Si 111 substrate and ranged from in-plane uniaxial stress, primarily along the 11-20 dir...

Lightand strange-baryon spectra are studied in a relativistic potential model of independent quarks taking into account perturbatively the correction due to one-gluon-exchange interaction along with that due to Goldstone boson exchange interaction between the constituent quarks and that due to center-of-mass motion. The baryons are assumed here as an assembly of independent quarks confined in a...

Medical image registration plays an important role in clinical diagnosis and therapy planning. This paper proposes an automatic method to register computed tomography (CT) and magnetic resonance (MR) brain images by using first principal directions of feature images. In this method, principal component analysis (PCA) neural network is used to calculate the first principal directions from featur...
