Irradiation of polymers is one of the most effective and economical methods for modifying their properties and for changing their applications. In this study, an extrusion grade polypropylene (PP) was treated by electron beam irradiation to produce a PP suitable for injection molding. Irradiation was carried out at different doses (0-80 kGy) under atmosphere air and at ambient temperature. Melt...

We are currently engaged in advancing research in human-robot cooperation with the goal of realizing service robots in homes and offices. In order to assist humans, robots must correctly identify the tasks that humans intend to perform, and then devise strategies to perform those tasks. To accomplish this, we first define the framework of a task model for assisting a human's work. The robot the...
