AT-cut Quartz crystal Microbalance (QCM) has been used as a high precision sensor for decades, which could detect the trace mass deposited on the crystal surface. The accuracy of QCM can be achieved ng level. When used as biosensor in liquid, the resonant frequency is not only affected by the mass change, but also by the liquid density and viscosity, which are greatly dependent on the liquid temperature...
for improving the present situation in the quality detection of plate making product line, a simplified homocentric square filter (SHSF) is proposed and implemented based on machine vision. Firstly, a hardware platform including camera, lens, light source, and encoder is designed to acquire high quality images. In order to automatically detect defects from the acquired images, the SHSF is designed...
SOA(Service-Oriented Architecture) can solve data exchanging problem between Heterogeneous Systems. In view of the difficulty of heterogeneous system integration which telecommunication operator faces, the Telecom Order Processing Subsystem Based on SOA is proposed in this paper. The implementation of this system adopts a multi-layer architecture and based on J2EE platform. The function of different...
The job shop scheduling problem (JSSP) is a well known NP-hard problem, and many algorithms have been presented to solve it, but the results are still unsatisfactory. In this paper, a hybrid discrete particle swarm optimization algorithm based on a two layer population structure is proposed to solve the JSSP, meanwhile add an improved simulated annealing algorithm to increase the ability of finding...
This paper mainly analyses two network instructional platforms, the Moodle and Ciwong, as them the typical cases, contrasts the details in the basic features, functions, features, instructional system design. At last, the author summarizes that a well instructional system design and a well platform the general principles of a successful network instructional platform.
This paper introduces an abstract high dependability framework for the implementation of embedded control software with hard real-time constraints. The framework specifies time-triggered sensor readings, atomic component invocations, actuator updates, and pattern switches independent of any implementation platform. In order to leverage model continuity, XML-based description of composite component...
Creditability modeling on real-time interaction specification for embedded systems on the distributed platform is a continuing challenge to developers. This paper presents a creditability modeling strategy that reduces complexity by separating data-related computational parts and time synchronization interaction among components. We introduce a notion of supervisor to discuss how to aggregate individual...
Hybrid control system is heterogeneous and difficult to design and modeling. This paper presents a component-oriented design methodology that reduces complexity by separating computational parts from interaction among components. We introduce a concept of supervisor to discuss how to aggregate individual component's computation into a coarse-grained composite component from a view of interaction semantics...
Complex control system is heterogeneous and imposes great challenges for control system design. This paper presents a component-based hierarchy modeling strategy that reduces complexity by separating data-related computational parts (components) and interaction among components (pattern). Architectures are composed hierarchically to manage heterogeneous models and achieve component and pattern reuse...
