Integrating the specifications and tools for IMS-Learning Design (IMS, 2003) into Moodle (Moodle, 2003), an open-source Learning Management System (LMS), is not just a technological question, but also relates to practical, pedagogical, and philosophical issues. This study documents the discussions and experiments of a team of teachers active in the Moodle(More)
Spreadsheets are used by millions of users as a routine all-purpose data management tool. It is now increasingly necessary for external applications and services to consume spreadsheet data. In this paper, we investigate the problem of transforming spreadsheet data to structured formats required by these applications and services. Unlike prior methods, we(More)
A new dynamic model and impedance control algorithm of a haptic feedback device for robotic teleoperation is analyzed in this paper. User forces applied to the haptic device through human hand movements are modeled as disturbances to the control system. Detailed analysis for modeling haptic device and human hand is provided and then a self-tuning Fuzzy PID(More)
