ESS Subsocieties and Technical Groups

Welcome to the Institute of Electronics, Information and Communication Engineers (IEICE), Engineering Sciences Society group web site for international students and overseas members.

Each subsociety and technical group in ESS is conducting active research, conferences, and workshops that are held periodically. You can find more information about each Technical Group such as its research field, its research objectives, etc.

System and Signal Processing

Circuits and Systems
As a long-established technical group in the institute, our mission is to continue fundamental research on theories on circuits and systems, and to analyze and develop new applications in this field in order to meet changing times and needs.

The technical group provides researchers with opportunities to make profound studies on basic and applied researches on theories on circuits and systems. Special themes are set for promotion of revitalization of technical groups in cooperation with VLSI Design Technologies, Digital Signal Processing, and Concurrent System Technology that belong to the same subsociety, as well as related technical groups such as Nonlinear Problems and Communication Systems.

Major research fields to be covered are as follows:　

Circuit theories (Linear and nonlinear, passive and active, time variant and time invariant, and lumped constant and distributed constant）　
Modeling and simulation

Concurrent System Technology
Our mission is to integrate and establish approaches listed below as Concurrent System Technology for important engineering issues for the future, such as cooperative and flexible system integration through intellectual autonomy and intercommunication focused on decentralized management, which will be realized by systematically studying concurrent modeling of distributed cooperative systems, autonomous decentralized systems, nonprocedural human-mechanical system such as groupwares, parallel/asynchronous/cooperative motion analysis, performance evaluation and methods for their realization, and by seeking concurrent control mechanism that enables effective, open and strategic operation of distributed asynchronous system including humans.

ITS (Intelligent Transportation Systems) Technology
It is desired to integrate information flows (communication networks) and automotive flows (traffic networks) to realize a better society by solving multiple problems in the social life, such as environmental, urban, disaster-prevention, welfare, and aging problems. Intelligent Transportation Systems (ITS) is an integrated system of information communication networks and transportation networks that helps reduce congestion, improve transport efficiency, increase safety, and preserve the environment, by integrating people, roads and vehicles into a single system using the cutting-edge information and communications technology. However, presentations and discussions on various technologies necessary for realization of the ITS, such as information and communications, navigation electronics, positioning and ranging, network control, information security, and image processing, have been somewhat limited by those studies being based on existing fields. Therefore, the present situation is that the organic integration and systemization of all these technologies are still incomplete and the academic improvements are desired.

The ITS Technology Technical Group works to put together presentations and discussions in various fields and provide opportunities for promoting organic collaboration of researchers and technologists from different fields. Through this, we would like to promote information exchange and interaction among researchers from various fields, and contribute to advance of the ITS technology.

Engineering Acoustics
Sound is indispensable to humans as a media for communication among humans and natural world, and for cultural activities such as music.

Also, with advancement of multimedia technology, opportunities for simultaneously using sound and video are increasing, leading to increasing importance of technology to handle sound. Recently, sound is used for various measurements and devices, not just having an aspect of being audible. Thus, acoustic science and acoustic engineering have a broad array of their applied areas with increasing importance.

The Engineering Acoustics Group would like to promote information exchange and interaction among researchers from various fields listed below, and contribute to advance of the engineering acoustics technology.

Systems for audible signal, acoustic wave and machinery vibration, and technologies related to these elements.　
Technologies for acoustic reception, acoustic transmission, signal transmission, processing, recording, and reproduction equipment.　
Technologies for devices, components and materials.　
Human-machine interface technology.　
Technologies for acoustic field and acoustic environment.　
Technologies related to musical acoustics and instrument.　
Technologies for audible signal analysis, processing and software related.　
Technologies for acoustic measurement and instrumentation.　
Basic theories of acoustics and newly applied technologies.

Safety
Safety is a desire for all humans. But the fact is that many damages are caused by accidents, which cannot be completely eliminated.

In the Institute of Electronics, Information and Communication Engineers (IEICE), a technical group specializes in safety related issues has been formed as a second-class technical group since May 1987. It has become a first class technical group in April 1998, and since then it has been conducting research and surveys on various kinds of safety issues, which has been classified into "Safety and Reliability", "Safety and Economics", "Transportation related Safety", "Industrial Machinery Safety", "Environmental Health related Safety", etc.

However, car accidents are still happening every day, and also approximately 2,500 people die of industrial accidents each year. Even deadly aircraft accidents sometimes make news, as well as unforgettable fire and other deaths. Not only similar accidents as ever are still happening, but also environmental health issues that may be a threat to lives become a topic of conversation lately. Internationally, functional safety has been taken up as ISO standards to increase the safety by improving electrical function in practice, though it is not stipulated.

For the above reasons, the IEICE has established "Safety Technical Group" within the Engineering Sciences Society group to play an active role in increasing the safety.
