OpenEnergySim: A Virtual World to Assess CO2 Emission


Intelligent Transport System (ITS) strategies can significantly reduce CO2 emissions of vehicles.
However, there is currently no low-cost yet effective method to investigate the impact of enegry-saving ITS measures on driving behavior. Further, there is no convenient collaboration platform to compare the results of such "green" ITS strategies at an international level.
Therefore, we implement OpenEnergySim, an online multi-user three-dimensional (3D) simulation space, which can serve three functions in one single consistent environment:
1. Visualization of microscopic traffic and CO2 emissions
2. Immersive driving of users in a simulated traffic network, where ITS measures can be applied and tested interactively
3. A shared real-time collaboration space aimed at international partners for studying and comparing the effects of green ITS strategies on CO2 emission reduction
OpenEnergySim can provide a unique platform for green ITS which fosters international collaboration and facilitates harmonization of models in the transport domain.

Optimizing everything / Optimal Society


Aiming at developing practical quantum optimization technology known as quantum annealing, we are working on exploring basic technologies that can overcome the limitations and applications in collaboration with multiple companies. The advantage of the method is that it can be used simply by formulating a cost function that draws the goal to be optimized once, but we are not limited to the original method. We extend it by considering a much easier problem, sequential optimization by learning, black box optimization, etc.. In particular, it is being applied to automated driving, logistics in factories, and evacuation guidance during disasters.

2)Targeted Applications / Industry
Applications to route search problems such as automatic driving of various vehicles, evacuation route guidance at the time of disaster, process scheduling and a large number of combination problems. We can provide a solution to combinatorial optimization in each industry. (Transportation / distribution, manufacturing, materials, drug discovery, etc.)

Oral Biofilm Functional Analysis: from “What Are They?" to “What Are They Doing?"


A large number of microorganisms inhabit the oral cavity, such as the teeth, gingiva and tongue, in the form of oral biofilm. The oral cavity forms an ecosystem where the host (humans) and parasites (microorganisms) coexist. Disruption of the balance of this oral ecosystem leads to dental caries, periodontal diseases and oral malodor, and even deterioration of dental materials.

Using leading-edge techniques of anaerobic experimental systems including original and unique devices, as well as the notion of "omics" such as metagenomics and metabolomics, we conduct research on oral biofilm functions. Knowledge of oral biofilms, from "what are they?" to "what are they doing?", enables us to address their control, that is, prevention of and therapy for oral biofilm-associated diseases.

Targeted Application(s)/Industry
Risk assessment of oral biofilm-associated diseases, such as dental caries, periodontal disease, oral malodor and aspiration pneumonia
Effects of medicine and food ingredients on oral biofilm function
Evaluation of biofilm-mediated material deterioration

Oxide Electronics

Our research group investigates creation of functional oxides and their functionalities. We synthesize thin films by pulsed laser deposition and sputtering methods and bulk specimens, and develop their novel synthetic routes. Recently, we are studying electrically conducting rare earth oxides, transparent room temperature ferromagnetic semiconductors, and layered superconductors with monatomic Bi layer. We will develop our materials design by extending materials range and performing oxide heteroepitaxy.

Targeted Application(s)
Collaborative research in fields of oxide electronics with novel electric conducting oxides and oxide spintronics with ferromagnetic semiconductors and novel ferromagnetic oxides.
