The need for higher equipment availability and lower maintenance cost is driving the development and integration of prognostic and health management (PHM) systems. Taking advantage of advances in sensor technologies, PHM systems enable a predictive maintenance strategy through continuously monitoring the health of complex systems. The core of PHM technology is prognostic which is able to estimate...
The recent advances in sensor technologies have made these small, tiny devices much cheaper and convenient to use in many different applications, for example, the weather and environmental monitoring fields, the hospital and factory operation sites, on the traffic road and moving vehicles and so on. Data loss and corruption is inevitable in wireless sensor networks due to the wireless interference,...
Today's large campus and enterprise networks are characterized by their complexity, i.e. containing thousands of hosts, and diversity, i.e. with various applications and usage patterns. To effectively manage and secure such networks, network operators and system administrators are faced with the challenge of characterizing, profiling and tracking activity patterns passing through their networks. Because...
Considering that freeway mainline has not only high speed but also the ability to store large amount of vehicles, this research proposed a new approach for controlling both freeway on-ramp and mainline. Based on local ramp metering strategy ALINEA, this approach controls both on-ramp vehicles and mainline shoulder lane vehicles according to real-time traffic condition of the ramp and mainline so that...
The reaction discussed in this paper is a complicated, multi-phase-catalyzed batch reaction to produce phenyl-pyretic acid by double carbonylation of benzyl chloride. In order to industrialize the production process, a significant engineering problem is to study the operation and control of this batch process. The first stage of study in this paper is to process the experimental data, then to build...
