The value of boiler drum level is usually obtained by operator visual reading to bicolor water level gauge, but it brings the problems such as inefficiency and bigger subjective error. In order to get value corresponding to the meter in the image, the processing algorithms based on Chow-Kaneko threshold processing and ISEF (Infinite Symmetric Exponential Filter) for image of the gauge are studied,...
The image brightness and contrast changes remain invariant when phase congruency changes. Specifically the monogenic filters, a new image feature detection method is proposed, which is based on phase congruency and the monogenic signal theory in this paper. The performances of Monogenic filters are excelled to that of Log-Gabor filters in theory, hence a greater amount of feature vectors are generated...
Temperature distribution during polymer sheet reheat phase in thermoforming is the focus of the research, which directly affects the quality of the final products. There are 3 ways of heat transfer that affect temperature distribution during the sheet heat process, which are conduction, convection, and radiation. The work aims to find the analogy of electrical and thermal parameters for electro-thermal...
In this paper, we studied the Apriori Algorithm and its performance, which is used to mine association rules. The algorithm for reducing the size of the candidate-itemsets is optimized. Meanwhile, the performance of algorithm is improved to reduce I/O spending by cutting down unnecessary transaction records.
Distributed real-time control system modeling (DRCSM) provides an abstract architecture for the implementation of distributed control systems with hard real-time constraints. In order to leverage model continuity, XML-based description of model informal description is required, which supports the reuse of components and model information interoperability. By separating the platform-independent from...
Because of the request of both function and time, the design of real-time control software become complex. This paper discusses a real-time control software design method based on time and function separating mechanism, which constructs two kind of pseudo-code :"function code" and "scheduling code", accompany with two executing engine - function machine and scheduling machine....
