The Construction of a Decentralized Energy Production System Using Small Methane Fermentation Systems That Utilize Exhaust Heat or Hot Springs and a Local Circulation System

NEXT
PREV
Features

In this project, we reduce the costs of energy production via anaerobic digestion by utilizing exhaust heat from a factory, which resulted in a positive energy balance, although the methane fermentation system tested was on a small scale.
Using small-scale methane fermentation with a positive energy balance, the initial investment is small, enabling a company to invest in, and install, such a system. This would decentralize energy production within an area. Moreover, this system not only produces energy, but is a basis for resource recycling.

Development of Recycling Technology for High-Water Content Sludge by Using Fiber Materials

NEXT
PREV
Features

The recycling rate of construction muds and sludge is very low because the water content of these muds is very high and direct reuse of them is very difficult. Therefore, a new recycling technology for high-water content sludge has been developed in this laboratory. This technology is called "Fiber-Cement-Stabilized Soil Method", and it uses fiber materials and cement. The main feature of this method is to mix the fiber materials with the sludge, and the fiber materials included in the soil produce several geotechnical merits.

Targeted Application(s)/Industry

The modified soils produced by this method can be used as ground materials for reinforced embankment of the river bank and soil structures because they have several features such as high failure strength, high failure strain high durability for drying and wetting and high dynamic strength.

Application of Nuroimaging Technique to Interface Evaluation

NEXT
PREV
Features

Nuclear power plants, chemical plants, ironworks and smelters, aircrafts and others that involve large-scale and complex systems yield many benefits to society and daily life, but a serious accident in such systems may result in dire consequences and significant damage. As long as there is human intervention of any kind, it is difficult to completely avoid human error. In light of this, it is crucial to have the mindset of "to err is human, (to forgive divine)." Takahashi Laboratory advocates the improvement of safety based on the harmonization of humans, machines and the environment. The object of our research is the human. Incorporating neuroscience approach and knowledge, we probe into human cognitive and behavioral traits and reflect our findings back into our research with the cooperation of this university's Institute of Development, Aging and Cancer as well as practicing specialists and technical experts. Through our broad vision, flexible mindset and creativity, we pioneer interfaces between humans and systems where safety is ingrained.

Visualization of Electron Motion in Matter by Means of Electron Compton Scattering

NEXT
PREV
Features

Properties of matter, such as reactivity and functionality, are determined by the motion of the constituent electrons. For this reason we aim at developing new spectroscopic methods, by using electron Compton scattering, that would visualize the electron motion for stable species and most importantly the change of electron motion in transient species, which is the driving force behind any chemical reactions;
(1) development of molecular frame electron momentum spectroscopy for momentum-space imaging of molecular orbitals in the three-dimensional form,
(2) developments of multiparameter coincidence techniques for studies on stereo-dynamics in electron-molecule collisions,
(3) development of time-resolved electron momentum spectroscopy for visualization of the change of electron motion in transient species.
We hope to conduct collaborative research with a willing company for a practical application of this technology in industry, and we are also prepared to provide academic consultations to companies interested in our research.

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

NEXT
PREV
Features

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.

Features

As modern supercomputers are getting larger and more complicated, it is not so easy to exploit their potential performance. It is necessary to develop a simulation code with considering various factors for both hardware and software reasons, and hence expert knowledge and experiences about supercomputing are often needed to achieve high actual performance. Our research interests focus on shaping future supercomputing systems and their applications, especially system software technologies for effectively using the future supercomputers. Also we are always exploring how to make good use of the state-of-the-art hardware and software technologies in order to enable unprecedented-scale and more advanced simulations.

From beginning (apply for use of our supercomputer) to end (get a solution), we can consistently support developing large-scale practical simulation, which is feasible only by using the supercomputer. As a supercomputing center, we have a long history of parallelizing and accelerating a lot of practical simulation programs.

Study on Tactile/Touch Feeling Sensor

NEXT
PREV
Features

Tactile sense and the sense of touch are multiple combinations of fundamental sensations, such as smooth and rough, soft and hard, dry and wet, and hot and cold sensations. These sensations are described with the information on force, distortion, temperature, stickiness and oscillation.
A tactile sensor corresponding to several types of human skin sensory receptors and an active tactile sensor system that is an integrated sensor structure imitating human haptic motions have been developed. These sensor systems allowed measurement of "Kansei" words that are extremely vague tactile feelings, and roughness, softness and temperature sensations. However, tactile sense or the sense of touch also includes other sensations and combinations of them. Therefore, to develop a sensor, it is important to define how the sensations and physical information relating to the sensations are obtained and what relationships exist between them.
In this research, the relationships between sensations, including fundamental sensations that have already been obtained and other sensations, and the relevant physical information are being investigated. Additionally, on the basis of the knowledge through the investigation, an advanced sensor system that allows obtaining haptic information is being developed.

Targeted Application(s)/Industry

The research is beneficial not only to life science but also to manufacturing fields.
