Message Transmission without Cellular Coverage, “Relay-by-Smartphone"

 
 
NEXT
PREV
特徴・独自性
  • Our technology provides the necessary method for sending messages even when the physical infrastructure is not available. The technology utilizes common smartphone WiFi functionality to send message in a multi-hop fashion. Thus it is possible to send message to people further away. Our technology has been designed to be based on Delay-Tolerant Networks (DTN), but the technical key idea is the combination of DTN and Mobile Adhoc Network (MANET), which can improve the message delivery in an area with high population density or where mobility are fixed such as evacuation center.
実用化イメージ

This technology can be used to distribute information during emergency situation such as after disaster. In addition, it is possible to provide additional services such as advertisement within shopping areas, distribution of coupons, exchange of information within small group during public events or uses as transceiver during group hiking. There is also possibility of using this technology to provide communications service in developing nations.

特徴・独自性
  • 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.
実用化イメージ

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.)

NEXT
PREV
特徴・独自性
  • In the dental magnetic attachments which retain dentures, superstructures of dental implants, and so on, the non-magnetic stainless steel containing nickel is used in order to reinforce their retentive force by a magnetic circuit. The surface layer of magnetic stainless steel which loses its magnetism by nitrogen-solid solution obtained from heating in nitrogen gas at high temperature, enable to form a magnetic circuit, which does not contain nickel at all, and to reduce its components and manufacturing processes. The method using the nitrogen-solid solution in this study is warrantable to manufacture the nickel-free dental magnetic attachment with high safety.

  • Hybrid materials that show multi-functions of polymer and nanoparticles are expected to be used in future industries, and thus many research and development have been actively conducted. However, since the affinity of polymer and inorganic nanoparticles is very low, in most of the cases, properties of different materials are incompatible in the hybrid materials. To create the hybrid materials with incompatible multi-functions has been considered a difficult task.

Using the neutron scattering technique, we search for macroscopic quantum phenomena in many-body electron systems, such as macroscopic singlet ground states in the quantum frustrated magnets and spin-fluctuation-mediated unconventional superconductors.
