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...

We examine recent results on measurements of the magnetic penetration depth in cuprate superconductors, with particular emphasis on our results obtained with the microstrip and parallel-plate resonator techniques. The results show that the magnetic penetration depth temperature dependence in YBa2Cu307-a is not consistent with a simple scaled weak-coupled BCS temperature dependence. We present t...

Total internal reflection fluorescence microscopy (TIRF), in both commercial and custom-built configurations, is widely used for high signal-noise ratio imaging. The imaging depth of traditional TIRF is sensitive to the incident angle of the laser, and normally limited to around 100 nm. In our paper, using a high refractive index material and the evanescent waves of various waveguide modes, we ...

We investigate the doping dependence of the penetration depth versus temperature in electron-doped Pr(2-x)Ce(x)CuO(4-delta) using a model which assumes the uniform coexistence of (mean-field) antiferromagnetism and superconductivity. Despite the presence of a d(x2-y2) pairing gap in the underlying spectrum, we find nodeless behavior of the low-T penetration depth in the underdoped case, in acco...

The factors in the drag equation (that is, the coefficient of drag, the density of the medium, and the cross-sectional area and velocity of the projectile) also determine the depth that a projectile will penetrate its target and the velocity of the projectile at a given depth of penetration. Ideally (that is, if a stable, nondeforming projectile passes through a homogeneous, infinite solid), th...
