Motivation
 The proposed joint research item is wide research, including
ubiquitous computing as well as manufacturing. Therefore, for the
study, various domain knowledge might be needed.
 To carry out the joint research item, studying during short term and
exchanging e-mail is not enough.
 For the joint research like joint workshops and seminars, long
cooperation between laboratories is required.

Goal
 Carrying out a long term or short term joint research by PhD
candidates
 Publishing the result in an international journal
 Implementing the result as a prototype system

Student Exchange Program

Types of programs
 Short term exchange program : During the vacation (2 month),
sending PhD candidate to the other laboratory for a joint research
 Long tern exchange program : During the semester (6 month),
sending PhD candidate to the other laboratory for a joint research

Methods
 Short term program : Each of PhD candidates introduces research
areas of the each laboratory. After that, they draw a common
subject and carry out preliminary research on the topic.
 Long term program : Joint research team choose one subject
among joint research items and carry out the studies of the topic.
Based on the result, the team publish a paper in an international
journal or implement a prototype system.

Deliverables
 Short term program : Preliminary report of joint research
 Long term program : Paper (International Journal) or prototype
system
