Ubiquitous e-Learning With Multimodal Multimedia Devices

The sharable content object reference model (SCORM) is a set of specifications and guidelines for the representation and operation of asynchronous distance learning. Since it was announced in late 1990s, the reference model has been used by software developers and academics in the development of authoring tools, learning management systems, and repositories for distance learning content. To date, most e-learning systems have been based on multimedia and Web technologies on personal computers. Our project, Hard SCORM, advances the field by implementing an integrated system which allows learners to read SCORM-compliant textbooks using multimodal multimedia devices. Hard SCORM employs a pen-like optical character reader device (called Hyper Pen) as an input mechanism. A computer, a personal digital assistant, or a cellular phone can be used for user behavior supervision using the hard SCORM machine. With an authoring tool, specially designed tags are printed in textbooks and recognized by hyper pen for user navigation control. In this way, users can read hardcopy textbooks in a traditional manner while the process of reading conforms to the SCORM specification. Part of the implemented system (Pocket SCORM on PDA) received the 2005 Brandon Hall Excellence in Learning Awards. The system has also been used by an airline company for online security checking and a high school for online mobile learning

An integrated fire detection and suppression system based on widely available video surveillance

An integrated system based on video surveillance is presented for automatic fire detection and suppression. The system is composed of two modules, including fire detection and fire suppression. The fire detection module makes full use of traditional CCD cameras for fire recognition. Some spatio-temporal features, such as color and motion, are extracted to detect fire in real time by utilizing sequential image processing techniques. Once a fire is detected, the system will control the fire suppression module to extinguish the fire automatically. It mainly consists of control device, mobile device, and water gun. Experiments performed in a large space hall show that the integrated system can detect a fire about a few seconds after ignition and automatically suppress the fire quickly.     

An object-oriented simulation framework for real-time control of automated flexible manufacturing systems

This paper describes an object-oriented simulation approach for the design of a flexible manufacturing system that allows the implementation of control logic during the system design phase. The object-oriented design approach is built around the formal theory of supervisory control based on Finite Automata. The formalism is used to capture inter-object relationships that are difficult to identify in the object-oriented design approach. The system resources are modeled as object classes based on the events that have to be monitored for real-time control. Real-time control issues including deadlock resolution, resource failures in various modes of operation and recovery from failures while sustaining desirable logical system properties are integrated into the logical design for simulating the supervisory controller.     

A knowledge-based approach to safety evaluation for plant start-up

To improve the safety of plant start-up operation, a safety evaluation system has been developed. As a key component in an operational design support system, the evaluation system examines any potential hazards during start-up operation simulation. The evaluation system is integrated into an operational design methodology which designs operable processes by proposing alternatives, examining process safety and operability, and modifying operating procedures or plant structures. Issues for both methodology and implementation of a G2-based expert system are discussed. Finally, the system is applied to an industrial hydrodesulphurization process.

Integration strategy for distributed intelligent systems

In this article, we describe a new framework for designing real-time intelligent control systems. An integrated intelligent system is a large knowledge integration environment that consists of both symbolic reasoning systems (expert systems) and numerical computation packages. These modular software programs are controlled by a meta-system which manages the selection, operation, and communication of these programs. This new architecture can serve as a universal configuration to develop high-performance intelligent systems for many complicated application domains in the real-time manufacturing process. As an example, an intelligent optimal control is utilized to illustrate the integrated intelligent control system.
