obtaining a seismic section with high temporal and spatial resolution was always one of the goals of seismic data processors and interpreters. accurate estimation of the thicknesses of thin beds is an important tool in this regard. the basic problem is that the wavelength of the signal must be similar in dimention to that of the bed thinness. if it is much longer than the bed thinness, the dete...

I discuss the relation between the nuclear response and the Green function describing the propagation of a nucleon in the nuclear medium. Within this formalism, the widely used expressions in terms of spectral functions can be derived in a consistent and rigorous fashion. The results of recent applications to the study of the inclusive electron-nucleus cross section in the impulse approximation...

This paper proposes a method for determining maturity levels of durian by using nondestructive vibration. The vibration is transferred directly through durian at a region between prickles located at the middle of durian. The measurement of frequency response from vibration of durian is performed by using laser doppler. The signal is processed for finding velocity of vibration, elastic constants...
