Outline of research activitiesMore than ten thousands people died caused fatal accidents in houses every year in Japan. Among them a number of the aged people died in falling down to flat floor even though without any steps. Floor slipperiness is usually represented as static friction coefficient at the slips in toe-off during last half of gait cycle. However, it is said that slips are also occurred at heel down to floor during first half of gait cycle. In order to evaluate floor slipperiness at heel down, it is necessary to measure the dynamic friction coefficient between footwear and floor under incremental vertical load during the heel down.
The wear of UHMWPE(ultrahigh molecular weight polyethylene) used in artificial joint is investigated more than 5 million cycles using joint simulator. The simulator is reproduced vertical load, flexion/extension, abduction/adduction and internal/external rotaion during gate cycle.

Outline of research activitiesWe are interested in the effects of the artificial environment of imaging systems on humans. We have studied both pros and cons effects. Examples of the good effects are viewers’ sense of power, immersion, and presence, in which the viewers feel as if they are in the space projected by the imaging system. The problem of quantifying these senses is that it is not possible to measure them with a measuring instrument. These characteristics related to human senses and sensitivity can quantified through subjective evaluations and questionnaires. At the same time, biometric measurements are performed to search for measurement items that may serve as biological indices. We are investigating the relationship between subjective evaluations and biological indices.
Conversely, undesirable effects are that a person watching 3D images or a shaky image may experience eye fatigue or a motion sickness. To clarify what can be done to minimize these undesirable effects, we are studying the relationship between the undesirable effects and presented images by subjective evaluations and biometric measurements. In this process, we measure eye movements, autonomic nervous system, and brain activity to quantify the degree of the undesirable effects. Based on these results, we have proposed measures to prevent and mitigate undesirable biological effects.- Desired cooperation

Outline of research activitiesThere are many application fields for the development of rational methods for inferring desired information from observed data. One of the techniques is the alternating least squares method for decomposing a matrix. This method is used in a wide range of fields from analysis of psychological data to image processing. However, the theoretical background of this approach does not seem to be fully clarified. I am conducting research with various interests, centering on research to clarify the theoretical background of the alternating least squares method.

Outline of research activitiesThe reinforcement learning (RL) learns the behavior through trial-and-error interactions with a dynamic environment. Since RL does not need the precise infromation on the desired output or desired action, it is considered to be applicable to many types of control problems. In order to develop the effective learning algorithm, we use the multiple actions as an output, and INGnet to process the sensor inputs. This learning system shows faster learning (left panel).
The signal transduction pathway (STP) is a sytem of intracellular reactions to govern the control of homeostasis. We are developing the computer model of immune system using STP to investigate the molecular mechanism of the emergence of diseases. Recently, we are developing the computer model to mimic the emergence of rheumatoid arthritis (right panel).- Desired cooperation

Outline of research activities(Numerical analysis)In scientific computing most computational time is spent in solving systems of linear equations. It is necessary to study an algorithm for solving the large linear system fast and stably. We have proposed several new iterative algorithms and preconditioning techniques.
Vertical axis is the number of iterations, horizontal axis is the index of residual vector, and we display the magnitude of the residual vector in the color. When this becomes black beyond the red, the error becomes large and when this becomes white beyond the yellow, the error becomes small.
(ICT)Distance learning is a way of learning remotely without being in regular face-to-face contact with a teacher in the classroom. We study the support system for the programming lecture in distance learning.- Desired cooperation

Outline of research activitiesIn recent years, computer CPUs have become more high-performance, and the number of CPU cores has been increasing year by year to 8, 12, 16, and so on.
As the CPU increases the number of cores, the software needs to be parallelized in order to obtain high performance and high throughput
dataflow.
This situation applies not only to high-performance computers but also to low-priced, limited-performance computers such as smartphones,singleboard computers or IoT devices.
In our laboratory, we are conducting research on the topic of that parallelized microservices using OS virtualization technology on computers attached to small sensor devices such as IoT and WoT.
On network devices, the scope of research is further, and the topic is packet and path control corresponding to traffic increase due to parallelization.- Desired cooperation

Outline of research activitiesResearchs are being conducted on care and welfare robot systems using soft pneumatic actuators and embedded controllers that can be used in ordinary homes. One of my research is the upper body support device for caregivers inclouding the part of arm will improve human affinity and do not interfere with caregiving movements. Because of an inexpensive, lightweight, and waterproof embedded controller, the support device can be used in small and humid spaces. The other one of my research is about the the walking training device for visually impaired children that is to reduce the burden on walking trainers, who are facing a shortage of manpower, and to reduce the physical and mental burden on the guardians. In addition, in my lab, we also develop the mattress that uses a flat soft actuator to change the position of contact between the body and the actuator by varying the applied pressure over time. Because when caring for the elderly and severely disabled, changing positions to prevent bedsores for bedridden patients which increases the caregiver’s restraining time and increases the mental burden.
