T i t l e：Upper Bounds of the Number of Channels on Multi-hop Wireless Networks and the Estimation with Computer Simulation
Abstract：Multi-hop wireless networks are autonomous systems of mobile nodes connected by wireless links and consist of nodes and wireless links. For multi-hop wireless networks,we assign channels to communication between two terminals. For this problem, modeling using the edge coloring of the graph theory has been proposed. In the modeling, each vertex corresponds to a terminal and each edge corresponds to communication of the terminal pair. In the modeling, all edges of the graph are assigned colors. This situation means that every pair of terminals assigned channels can communicate with each other simultaneously. Therefore,this modeling is not so realistic. In this paper, we assign colors to some edges under a condition, and consider upper bounds of the number of colors with theoretical aspect. Then, we estimate the number of colors with computer simulation.

T i t l e：Numerical Investigations for Stable Calculation of Meshless Time Domain Method: Influence of Node Alignment on Numerical Stability
Abstract：The stabilizing calculation of Meshless Time Domain Method (MTDM) is numerically investigated. In addition, the influence of a node alignment on the numerical stability is also investigated. MTDM does not require finite elements or meshes of a geometrical structure as well as other meshless method. In MTDM, only the necessary information is the location of nodes, and the arrangement of the node structure of electric fields and magnetic fields.
The purpose of the present study is to develop the numerical code for analyzing electromagnetic phenomena, and the influence of the node alignment on stabilized calculation is investigated.

T i t l e：High-performance Method for Analyzing Shielding Current Density in High-temperature Superconducting Film with Cracks
Abstract：A high-performance method is proposed for analyzing a shielding current density in a high-temperature superconducting film containing cracks. After an initial-boundaryvalue problem of the shielding current density is spatially discretized with the finite element method, the resulting ordinary differential system is solved by using the modified constitutive-relation method. By means of the proposed method, applicability of the scanning permanent-magnet method to crack detection is investigated numerically.

T i t l e：Investigation of Meshless Time-Domain Method with Interpolating Moving Least-Squares Based Shape Functions
Abstract：In the meshless time-domain method (MTDM), the radial point interpolation method (RPIM) based shape functions have been employed. This is because RPIM shape functions satisfy the Kronecker delta function property. In this paper, to investigate the performance of MTDM with other kind of shape functions, the interpolating moving leastsquares (IMLS) based shape functions are applied to MTDM. Since IMLS based shape functions also satisfy the Kronecker delta function property, a new scheme for electromagnetic wave propagation simulations using MTDM may be generated.

T i t l e：Simulation of Wideband Chaotic Vibration Energy Harvester Based on Finite Element Method
Abstract：Electromangetic vibration energy harvesters (VEHs) with chaotic motion are are developed for wireless sensors. It is known that the chaotic VEH has wider operation frequency range for power generation. In this work, the reason why the target VEH has such feature is clarified from the view point of the magnetic energy which is computed using the finite element method.

T i t l e：Particle-based Fluid Simulation with Implicitly Defined Deforming Obstacles
Abstract：In this paper, we present a particle-based fluid simulation method with deforming obstacles. In order to define the geometry of deforming boundaries, we employ the implicit function form. Our fluid simulation is based on the Moving Particle Semi-implicit (MPS) method that provides simulation of incompressible flow. Although many of particle-based algorithms require a set of boundary particles representing obstacles, our method works without particle representation of obstacles.

T i t l e：Influence of Network Topology and Stubborn Agent Centrality on Consensus
Abstract：This research investigates the influence of stubborn agents in various network topologies,with agents located at different positions. We consider agents with different centralities as the stubborn role and observe the results in both the overall behavior (convergence/divergence) and the convergence time. We observed that the topology of the network and the position of the stubborn agents make a considerable difference in the convergence speed and the overall behavior.

T i t l e：Simulation Analysis for Magnetization Process of Torus Ring Clusters with Different Radius
Abstract：Monte Carlo simulations were performed for magnetization process of torus ring clusters with different ring radius. Simulation results show not only ordinary hysteresis curves but one include plateau region. As a result, it is clearly seen that plateau region and ordinary curve have closure domain state and head-to-head state, respectively.

Abstract：We proposed a simple and effective method to evaluate the closeness of eyes during an evaluation of a small database of portraits. The experimental results show that closed-eye state can be detected only using a normalized and shifted gray scale histogram of each eye and finally comparing these histograms using the coefficient of correlation.

T i t l e：Optimal H2 Integral Servo Problem
Abstract：A design method of optimal H2 integral servo controller for constant reference input is proposed based on optimal H2 controller framework. The optimal H2 integral controller is to establish a way to find the admissible controller such that the controlled plant is stabilized and guarantee to track a constant reference signal while minimizing the H2 norm of the closed-loop transfer function of the controlled plant from disturbance to the controlled output. Therefor, the controller give a effective scheme for controlling oscillatory system with constant reference and disturbance signal.
