In this paper the flow behaviour over a number of car bodies is studied. For this purpose the unsteady 2-D incompressible Navier-Stokes equations have been applied. After averaging and nondimensionalizing the equations, the system of equations has been transformed from the Cartesian (x-y) coordinates to a body fitted generalized (-) coordinate. As the flow is incompressible, the density in the ...

This paper presents synchronization of coupled chaotic circuits as an array topology when coupling strength has different value depending on distance between the chaotic circuits. By using computer simulations, we observe interesting synchronization phenomena. Namely, several types of synchronization are observed by depending on arrangement method of chaotic circuits.

Recent results from lattice QCD calculations relevant to particle physics phenomenology are reviewed. They include the calculations of strong coupling constant, quark masses, kaon matrix elements, and D and B meson matrix elements. Special emphasis is on the recent progress in the simulations including dynamical quarks.

A novel angle detector for laser beams is designed in this paper. It takes advantage of grating coupling to couple the incident light into a slab waveguide; and, the incident light’s angle can be determined by reading the outputs of light detectors within the waveguide. This device offers fast-responding on-chip detection of laser beam’s angle. Compared to techniques based on quadrant photodiod...

A new CCII-based circuit for the simulation of mutually coupled circuits is presented. The circuit uses six commercially available plus-type secondgeneration current conveyors (CCIIþs), six resistors and two grounded capacitors. The primary self-inductance, the secondary self-inductance and the mutual inductance can be independently controlled using three different resistors. SPICE simulation r...

We address the problem of distributing a parallel simulator based on the Local Time Warp approach across loosely coupled domains, like the Internet. We propose a mechanism to cope with problems which may arise because of unpredictable delays in communication between clusters which compose the simulator. The proposed scheme is completely distributed and is able to globally tune the entire simula...
