We study the optical response of eccentric nanoshells (i.e., spherical nanoparticles with an eccentric spherical inclusion) in the near and the far field through finite-difference time-domain simulations. Plasmon hybridization theory is used to explain the obtained results. The eccentricity generates a far-field optical spectrum with various plasmon peaks. The number, position, and width of the...

The prediction of pollutant concentrations in the coastal waters is essential for water quality control. The description of physical processes and their implementation in computer models shows that there is neither a “complete model” including all important spatial and temporal scales of the dominant processes nor a standard procedure for the coupling of models. This is explained by deficiencie...

This paper proposes an adaptive neural network composed of Gaussian radial functions for mapping the behavior of civil structures controlled with magnetorheological dampers. The online adaptation takes into account the limited force output of the semi-active dampers using a sliding mode controller, as their reaction forces are state dependent. The structural response and the actual forces from ...

[1] Regional surface wave observations offer a powerful tool for determining source properties of large earthquakes, especially rupture velocity. Supershear ruptures, being faster than surface wave phase velocities, create far-field surface wave Mach cones along which waves from all sections of the fault arrive simultaneously and, over a sufficiently narrow frequency band, in phase. We present ...

Photonic devices can be developed, and their working principle can be understood only by considering the phenomena taking place at the nanoscale level. Optical properties of plasmonic structures depend on their geometric parameters and are sensitive to them. Recently, many advanced methods for the preparation of nanostructures have been proposed; however still, the geometric parameters are inac...

Tsunami is one of the most severe natural disasters faced by regions around the rim of oceans, usually generated by submarine earthquakes (usually with magnitude larger than 7.0), volcano eruptions and large landslides. Submarine earthquakes are the most common tsunami sources. As we know, the prediction of an earthquake is still not satisfactory with today's technologies, in fact, for most ear...

The finite element model of a new staggered story isolated structure is established. Using the time-history analysis method, dynamic response state at each time step calculated by integrating acceleration data step-by-step. Three different types seismic waves (ordinary wave, near-fault impulse far-field quasi harmonic and long-period wave) are input respectively for history analysis. result ind...
