The cavity expansion theory is most widely used to predict the depth of penetration of concrete targets. The main purpose of this work is to clarify the differences between the spherical and cylindrical cavity expansion models and their scope of application in predicting the penetration depths of concrete targets. The factors that influence the dynamic cavity expansion process of concrete mater...

Polarization gating has been widely used to selectively probe the structure of superficial biological tissue. However, the penetration depth selectivity of polarization gating has not been well understood. Using polarized light Monte Carlo simulations, we investigated how the optical properties of a scattering medium and light collection geometry affect the penetration depth of polarization gat...

The need for the control of the depth of weld penetration has been and remains of a long term interest in the automated welding process. In this study, the relationship between the depth of weld penetration and the acoustic signal acquired during the laser welding process of high strength steels is investigated. The acoustic signals are first preprocessed by the spectral subtraction noise reduc...

We have investigated the effect of Airy illumination on the image quality and depth penetration of digitally scanned light-sheet microscopy in turbid neural tissue. We used Fourier analysis of images acquired using Gaussian and Airy light-sheets to assess their respective image quality versus penetration into the tissue. We observed a three-fold average improvement in image quality at 50 μm dep...

In this paper, we highlight our past experiences on fast penetration depth computation and its applications in different areas such as physically-based animation, 6DOF haptic rendering and robot motion planning.

The results of first-principles calculations of the electronic structure and the electron-phonon interaction in MgB2 are used to study theoretically the temperature dependence and anisotropy of the magnetic-field penetration depth. The effects of impurity scattering are essential for a proper description of the experimental results. We compare our results with experimental data and we argue tha...

Given two objectsA andB, we denote their configuration space as C-space and each configuration or point in C-space corresponds to relative configuration (i.e., position and orientation) of A w.r.t B. In the rest of the paper, we assume that A is movable and B is fixed. For 2D objects, C-space has 2 degrees of freedom (DOF) if A can only undergo translation motion, and 3-DOF if we take into acco...

Conventionally, the quality of the weld is ascertained only after the welding has been completed through the use of NDT techniques. A lot of time, material and manpower is wasted before one comes to know about the soundness of the weld. These limitations can be overcome if the weld is continuously monitored in real time for the assessment of defects using appropriate NDE sensors. This paper hig...

– A phenomenological theory is suggested to explain the experimentally discovered “paramagnetic peculiarity” and the unconventional change of the energetic state of a layers of high Tc of Y-Ba-Cu-O in the vicinity of the phase transition. The physical conditions are found under which these peculiarities are revealed. It is shown that the suggested theory qualitatively describes the experimental...
