Users may ask a service robot to accomplish various tasks so that the designer of the robot cannot program each of the tasks beforehand. As more and more open-source knowledge resources become available, it is worthwhile trying to make use of open-source knowledge resources for service robots. The challenge lies in the autonomous identification, acquisition and utilization of missing knowledge ...
The objective of this study was to examine the effect of bottle and can openers, operating postures on flexion angles of the hand; muscles activities and subjective rating when opened bottle caps and cans. Twenty participants performed two-bottle uncapping and two can opening tasks with five bottles and can openers on two operating postures (i.e. standing and sitting postures). In addition, the...
BACKGROUND AND OBJECTIVES Handedness, or the inherent dominance of one hand's dexterity over the other's, is a factor in open surgery but has an unknown importance in robot-assisted surgery. We sought to examine whether the robotic surgery platform could eliminate the effect of inherent hand preference.

From a machine learning standpoint, the PAN 2012 Lab contest had one major challenge. In all authorship attribution tasks, the number of training documents was extremely low. We extended our previous work, in which compression distances to randomly selected prototype documents from the training corpus were used as feature representation. A supervised multi-class classifier was learned in the re...
Abstract The important role of student agency in collaborative problem-solving has been acknowledged previous mathematics education research. However, what remains unknown are the processes open-ended tasks that draw on real-life contexts and demand argumentation beyond “mathematical”. In this study, we analyse a video recording two groups (each consisting four students) taking part problem-sol...
