This paper describes the development of a novel multi-wheel stair-climbing wheelchair. The necessity for mobility aid technology for elderly and handicapped people that has “minimal invasiveness for use in an historical environment” is described. With this goal in mind, a prototype of a novel wheelchair having a stair-climbing function resulting from transformable wheeled four-bar linkages is proposed...
Since barrier synchronization is a simple means to guarantee the order of data producing and data consuming, it is often used in parallel programs. However, barrier synchronization causes the processors' idle time to increase. To reduce the overhead of barrier synchronization, we have proposed an algorithm which eliminates barrier synchronizations and evaluated its validity experimentally. In this...
We have developed a system that allows teachers to monitor the classroom learning of students (novice programmers) in real time and provide support to groups of students experiencing common problems. This system has a program animation function which keeps a historical record of the students' operations as they go through a program while trying to understand it. By analyzing this record, the system...
We have developed a system that informs lecturers regarding real-time learning situations in the classroom and helps them provide support for students (novice programmers) experiencing common problems. This system has two functions. The first is a program animation function which keeps a historical record of the students' operations, and analyses this record to provide the information about difficulty...
The pretreatment effects using UV light illumination and DMF soaking on bulk and track etching rates of PET films were investigated. The wavelength of illuminated UV light plays an important role in sensitizing track etching. Illumination with the light at wavelengths longer than 320 nm showed strong enhancement in the track etching rates without influence on the bulk etching rates, whereas light...
