The traditional industrial factory automation, the so-called SCADA (Supervisory control and data acquisition), based on OPC (OLE for Process Control) technology. In recent years, under the impact of information technology, OPC technology is now actively updated to the new standard OPC UA (Unified Architecture). SCADA and the Internet of things, in...
Conference Paper
This article argues that aesthetic preference judgment might not depend on aesthetic prototypes, but on object’s affective qualities. That is, when an object is presented, one perceives not only its feature organization, but also the perceived affective quality where it presents in some specific situations. Therefore, this study tries to find out t...

Traditional supervisory control uses special hardware, like PLC, and special software, like IEC 61131-3. This research uses software in popular language to integrate hardware generally available in the market to form a low-cost easy-to-upgrade supervisory control system. The proposed web-based multiple stations supervisory control framework include...
Article
Musty and earthy odor is present in the source water of Feng-Shen Waterworks (FSW) and Cheng-Chin Lake Waterworks in southern Taiwan year round. In this study, oxidation processes, particularly the three common oxidants, chlorine, potassium permanganate and ozone, have been demonstrated to reduce the musty odor in a semi-batch reactor. Ozone was ap...
Article
In this paper, the finite element and abductive network methods were used to obtain a runner-system design to reach minimum warppage on an injection moulded parts with free-form geometry. This study uses the diameter and length of the runner-system as the major control parameters. In the model creation stage, FEM simulation data were used to deriva...
