Co-OrganizerMasami Iwase (Tokyo Denki Univ.)
ObjectivesThe system design and the numerical simulation are important for the system integration in order to save its cost to integrate a large system. The purpose of this session is to share the state-of-the-art design and numerical simulations with analysis and experiments for the system integration.

OS5: Coupled-Simulation and Co-Simulation

OrganizerDaisuke Ishihara (Kyushu Inst. Tech.)
Co-OrganizerTomohiro Sawada (Natl. Inst. of Adv. Indus. Sci. and Tech.)
Tomonori Yamada (The Univ. of Tokyo)
ObjectivesThe different subsystems form a coupled problem when the independent solution of any one subsystem is impossible without simultaneous solution of the others. The coupled-simulation and co-simulation are the computational approach to coupled problems. The objective of this session is to share the state-of-the-art coupled-simulation and co-simulation, where the topic includes the numerical modeling, algorithms, program and software development, and applications in coupled problems.

OS6: Multi Dimensional Communication Networks

OrganizerKenichi Ito (Niigata Inst. of Tech.)
Co-OrganizerHisashi Morishita (National Defense Academy)
ObjectivesWe will discuss the communication about the infrastructure or the application, the communication methods and the high reliability from diversity of communications

OS7: Advanced Numerical Analysis and Software Technology

OrganizerAmane Takei (Univ. of Miyazaki), Hiroshi Kawai (Toyo Univ.)
ObjectivesNumerical simulation frameworks are widely used in industries as package-software those are sold by software benders. On the other hand, open source software: OSS’s numerical simulation frameworks are also researched and developed energetically by research groups centered on Universities. For example, ADVENTURE developed by a research group centered on the University of Tokyo, and UG4 developed by Goethe University Frankfurt, Germany, are good examples. These source codes are released, and these are possible for a researcher to develop a simulator with new functions by adding the code required in his own research. The objective of this symposium, mathematics such as basic equations and linear algebraic solvers, parallelization techniques, the software development methodology: SDM will be discussed.

OS8: Numerical Harmonic Analysis and Signal Processing

OrganizerKensuke Fujinoki (Tokai Univ.)
Co-OrganizerToshio Suzuki (Tokyo Univ. of Sci.)
ObjectivesWith recent technological advances, we are managing large amounts of data, which requires efficient representations and processing. Applied and numerical harmonic analysis, whose purpose is to provide efficient representations of functions or data, has developed not only for harmonic analysis in mathematics but also for the other scientific fields, such as electrical engineering and computer science, especially signal processing. Considering such a situation, we selected the topic for the organized session as “Numerical Harmonic Analysis and Signal Processing.” The aim of this session is to explore an intersection between applied mathematics and its related applications, and discuss recent developments in harmonic analysis and signal processing.

OS9: Complex Networks and Complex Systems

OrganizerAtsushi Tanaka (Yamagata Univ.)
ObjectivesComplex systems have been fascinating subject of self-organization, pattern formation and other nonlinear phenomena. In these days, the study of complex networks has been popular all over the world. It includes not only mathematics and physics but also biology, economics, technology and social science.
Recent developments of computers and simulation techniques have enabled us to analyze and simulate those big-data resources. The aim of this organized session is to provide a forum for exchanging ideas and discussing recent developments in complex systems and complex networks in the various fields of researches.

OS10: Computational Electromagnetics and Its Applications

OrganizerHideki Kawaguchi (Muroran Inst. of Tech.)
Co-organizerHajime Igarashi (Hokkaido Univ.), Kota Watanabe (Muroran Inst. of Tech.), Yoshihisa Fujita (Ritsumeikan Univ.)
ObjectiveNumerical simulations of electromagnetic fields are quite various and wide research area. The electromagnetic fields are classified into electro- and magnetostatic, quasi-static and high-frequency or electromagnetic wave fields. On the other hand, there are several numerical schemes for partial differential equation such as the finite-difference method (FDM), finite-element method (FEM), boundary element method (BEM), and so on. In addition to such the view point of numerical techniques, industry applications of the computational electromagnetics are also important and active research fields, in which inverse problem and optimization technique are closely connected. The aim of this organized session is exchange of new results in computational electromagnetism and its engineering applications.

OS11: Simulation in Nuclear Fusion

OrganizerYoshihide Shibata (NIT, Gifu Coll.)
Co-OrganizerSeiki Saito (Yamagata Univ.)
ObjectivesThe numerical simulation in nuclear fusion has played an important role for the realization of the nuclear fusion reactor. For example, the design of ITER (International Thermonuclear Experimental Reactor) is based on calculation results such as simulations of plasma physics, fusion engineering, and fluid dynamics. Therefore, the development of high-performance numerical techniques in nuclear fusion have contributed to the remarkable development of these fields. The aim of this organized session is to provide a forum for exchanging ideas and discussing recent developments in the numerical simulation in nuclear fusion.
