This paper proposes an advanced cut-and-paste editing for three-dimensional models. We introduce a new parameterization technique based on constrained B-spline surface/volume fitting. Our cut-and-paste editing is performed on this parameterization. In our method, a parametric volume is generated so that its isoparametric surface fits to the base surface and(More)
Education of design engineering has started to change in response to the advancement of computer technology. This paper proposes a new design engineering educational framework using an e-learning system called ShareFast, a Semantic Web-based software for document management system with workflow. The software offers a function to keep tracks of learner’s(More)
Design is a central activity to all types of engineering. Each engineer must be equipped with skills in design engineering. Education of design engineering, as a result, has now started to change in response. This paper proposes a design engineering educational framework using ShareFast, an open source, client/server application for document management(More)
On-Demand Bus is a Demand Responsive Transit (DRT) service that passengers will be transported by the vehicles after they reserve a seat. The vehicle won’t move if there is no reservation and the efficiency is expected as a new transportation service. It allows potential passengers to request service via the Internet or mobile phone, with requests(More)
A woman between 50 and 60 years of age was diagnosed with a rectal carcinoid tumor and synchronal multiple liver metastases. We performed a transanal local resection of the rectal tumor, which was 10mm in diameter. During surgery, ultrasonography revealed 8 hypoechoic masses in the liver, and we performed a partial hepatectomy (S5/6, S8) and administered(More)
This paper proposes predicting the operation function (POF) for the workflow-based knowledge management software. POF is a function of the system that can estimate the documents which software users want to see and provides the users not only with proper documents but also unexpected knowledge which another users operation reflected. The system stores the(More)
