Classical wave-equation is solved using Multiresolution Multiwavelet (MW) basis functions in one- and two-dimensional space. The time progression operator is represented using Cayley formalism in order to avoid instability of the solution. Stable solutions are obtained for different initial conditions.
Physiome and systems biology have been recognized as emerging and important research areas that can integrate quantitatively growing knowledge about biological structure and physiological functions at multiple scales of time and space. For the integration, it is important to build physiologically plausible and sharable mathematical models that can be used for dynamic simulations of functions at multi-scale...
The authors have been developing a simple partial discharge model to analyze phase-resolved partial discharge characteristics such as ! -n characteristics. The simple model is simply based on the Whitehead's three-capacitance equivalent circuit model for partial discharges. The authors proposed an integral equation based on the fluctuation of delay time of each partial discharge inception. They already...
Short signature schemes are useful for systems where signatures are typed in by a human or for systems with low-bandwidth channels and/or low-computation power such as PDAs or cell phones. In this paper, a new short signature scheme is proposed. Our scheme is more efficient than Zhang et al.'s scheme and BLS scheme. Based on the hardness of k-CAA problem, we provide a rigorous proof for our scheme...
Power supply failure will cause major social loss. Therefore, power supply systems have been required to be highly reliable. This research deals with a significant and effective method to decide the investment in a power system damage of the power supply on the society. In CMD2007 Korea, we proposed mean-variance approach to replacing unreliable units in a power system. This paper extends the method...
