TIME-DOMAIN ANALYSIS OF OPEN RESONATORS. ANALYTICAL GROUNDS.

The Open Source Proving Grounds

Open source software is an attractive target when developing and evaluating software defect detection tools. This position paper discusses some of the benefits and challenges I have encountered as a researcher interacting with the open source community. The Cooperative Bug Isolation Project (CBI) explores ways to identify and fix bugs in widely deployed software. We use a mix of lightweight ins...

Large Scale Experiments Data Analysis for Estimation of Hydrodynamic Force Coefficients Part 1: Time Domain Analysis

This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...

On the Analysis of Resonators Using Finite-Difference Time-Domain Techniques

Because a resonator with perfect electrically conducting (PEC) walls has no complications with absorbing boundary conditions and, for canonical geometries, the resonant frequencies are trivial to find, resonators are often used for analyzing the performance of finite-difference time-domain (FDTD) methods. However, when testing the performance of boundary implementations in an FDTD scheme, one s...

A Probabilistic Three-Phase Time Domain Electric Arc Furnace Model based on analytical method

An electric arc furnace (EAF) is known as nonlinear and time variant load that causes power quality (PQ) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. One of the most important problems to study the EAF behavior is the choice of a suitable model for this load. Hence, in this paper, a probabilistic three-phase model is proposed base...
