In process...
… As a student of architecture, time and time again I am inpressed by its powerful imagines. The more I study and learn, however, the more I question. What is the truth beyond those fantastic imagines? What is the nuture of Architecture? Is there any basic way or process to approach the work of …

Human Problem Solving in Process Control
A review of literature from the domain of process control is provided, in which the complexity of the process control task is illustrated. It is argued that the role of the human operator is evolving to be primarily that of a problem solver. Following a brief review of literature related to problem …

A CNC machine guiderail wear in-process monitoring system
This research investigates and establishes a system for monitoring the guiderail wear on medium size CNC machines. The system possesses the function of measuring the wear state on guiderails in an in-process way, which is more functional and efficient than the traditional method. In this research, …
