In this paper, we compare the computational power of two-way Watson–Crick automata and Quantum finite automata. The language $${\text{L}} = \left\{ {\left. {{\text{xx}}} \right|{\text{x}} \in {{\mathbf{a}},{\mathbf{b}}} \right\}^{*} } \right\}$$ is accepted by but not quantum

We calculated propagation constants of supermodes for two-dimensional two-slab waveguides, with small core gap, using secondorder perturbation expansion from gapless slab waveguide system, and compared our results with the existing works. In the perturbation calculation, we used trapezoidal method to calculate the integral over the transverse direction in space and obtained second-order expansi...

In this thesis we deal with two geometric optimization problems: Minimizing Absolute Gaussian Curvatue Locally in Meshes and the Solution path of the Slab Support Vector Machine. In the first part, we show that given a polygon C in R it is in general algebraically hard to find a point in R3\C at which the absolute Gaussian curvature with respect to C is minimized. By algebraically hard we mean ...

We demonstrate the existence of surface waves in two-dimensional photonic crystal slab edges. In finite-sized air-terminated photonic crystal boundaries, the slab-edge mode turns into a lasing mode under pulsed optical pumping conditions. Analyses of the modal behaviors of the slab-edge modes by means of calculations based on the plane wave expansion method and the finite-difference time-domain...

Subduction of oceanic lithosphere occurs through two modes: subducting plate motion and trench migration. Using a global subduction zone data set and three-dimensional numerical subduction models, we show that slab width (W) controls these modes and the partitioning of subduction between them. Subducting plate velocity scales with W(2/3), whereas trench velocity scales with 1/W. These findings ...
