Division of Systems Research

The Division of Systems Research (DS) aims to develop key technologies contributing to sustainable a nd ecological society, such as advanced energy conversion, transmission, and utilization technologies, bioremediation and substance synthesis using microorganisms, energy and environmental impact assessment methods from various points of view. For the effective use of these technologies, the DS also carries out leading- edge researches on wireless communication system and urban traffic management system, etc.

Conversion Systems Section

This section is engaged in research aimed at the creation of high-efficiency, cutting-edge energy conversion systems. This includes the development of power generation and storage systems that utilize minute amounts of hydroelectric power, the improvement of coal-combustion technologies, the conversion of waste-material energy for use as a resource, and the measurement of thermofluid phenomena using pressure- and temperature- sensitive paint.

Network Systems Section

The Network Systems Section is pursuing cutting-edge researches, such as planning and control method of energy system connecting various electricity/heat sources and d emands, future visons of environmentally sustainable urban transportation system and its optimum management, and wireless communications necessary for realizing such infrastructures.
Wireless Systems
We investigate and develop a wide variety of wireless communications that are essential for the realization of an environmentally friendly sustainable human society. Our research covers basic theories to real applications, focusing especially on the total optimization of sensing and control in large-scale systems with wireless communications, which is required in energy/industrial systems, ITS (intelligent transportation systems), and disaster support systems. From the viewpoint of communications media, our scope includes not only radio waves but also optical wireless communications, power line communications, and more.

Transport System
Towards the realization of an environmentally sustainable transportation system considering the widespread use of autonomous vehicles in the near future, we propose that future visions of urban transport systems should explicitly consider the constraints of envir onmental impact and energy consumption, and de - velop and evaluate transportation policy measures based on a rigorous under - standing of individuals’ travel behaviors. Our research topics include the efficiency of the use of electric vehicles, counter - measures to reduce traffic accidents, optimum management of urban road traffic using autonomous vehicles, and fulfillment of the mobility needs of mountainous rural communities.

Circulation Systems Section

The Circulation Systems Section develops various key technologies related to ecological material conver- sions and circulation, and also assesses such technologies when they are deployed in society and develops the necessary assessment methods. Furthermore, the section is pursuing research and development on technologies that reduce environmental impact, recycling technologies, circulation systems of renewal materials, and other technologies that contribute to reducing the consumption of resources.
Environmental and Energy Biosystems
Among the various technological developments toward solving environmental and energy problems, bioremediation and substance synthesis using microorganisms are expected to be used as energy-saving technologies that can be ap - plied on-site. We have found that solid-phase humus (humin) has an external-electron-mediating function for various anaerobic microorganisms, in which humin supplies the external electrons to the microbial cells directly and acti - vates them. We are studying the mechanism of this external-electron transfer and developing a microbial electrochemical system. It is expected that the s tudy wi ll elucidate th e b iological energy network working in the natural environment and lead to the development of new tech - nologies for environmental remediation and material biosynthesis by the activation of microorganisms using a small amount of electricity that can be supplied by solar cells.

Study on renewable energy and environment/ecology system assessment for achieving sustainable society in harmony with nature
We are conducting research to realize a sustainable society by assessing the impact of energy and the environment. Focusing particularly on land use and spatial evaluation of the natural environment, we are working on the comprehensive solution of problems related to renewable energy( biomass, small-scale hydropower, solar power, etc.), ecosystem services, economy, and society. Along with environment assessments ranging from small-scale field surveys to global-scale assessment, we are engaged in research with an interdisciplinary approach combining, for example, spatial analysis such as GIS( Geographical Information System), AI, UAV, and field surveys.

Energy Resources Recycling Engineering
In Japan, the self-sufficiency of energy supply is quite low, and also, the population is expected to decline. An important and demanding task is deciding how to maintain our activity while reducing energy consumption. All materials necessary for our lives are on a cycle: th ey are received from the earth, used in human society, and then returned to the earth. We study waste management, treatment, and disposal in an energy- saving material cycle.
