The use of wireless sensor networks has enabled the process industry to collect a vast amount of hitherto unknown data by making physical monitoring of the underlying processes and equipment practically and economically possible. Wireless communication has led to new applications in the field of wireless process automation which in the past were subjected to economical, physical and technological...
Tire sidewall marking are the information for customer usage, safety, regulatory of national and manufacture internal trace ability. The consequence is high severity when marking are not correct. Hence, the marking verification is very important, because tire sidewall marking is arc-distribution, it is difficult to extract the feature vector. To solve this problem, a moment-based method is presented...
In industrial processes, fault detection and diagnosis is traditionally applied separately to process and equipment without relating the information on both systems. This paper shows the interaction during fault propagation between the process and its auxiliary systems, i.e. mechanical, electrical and utility systems. Evidence is given with an industrial case study. The relevance of this finding is...
As friction is the main nonlinear resistance in the flight simulator servo system which can lead to overall flight simulator performance degradation. The mathematical model of flight simulator servo system was created based on a three-axis servo system and the LuGre friction model was analyzed. Exponential approach law was introduced into variable structure control and the robust controller was realized...
According to the deficiency of real-time and interaction in current visual simulation of automobile engine, a visual simulation of automobile engine was proposed based on Virtual Reality (VR). Firstly, focusing on four-stroke and reciprocating-piston automobile engine, the mathematical model of crank-connecting rod was established, and then that of valve train was obtained by the result data of ADAMS...
In this paper, on the basis of AHP and the comparative pricing in the current market value method, a software pricing evaluation model is introduced reference the existing software price evaluation method. Based on this model, we analyze the existing open-source software profit model and give the evaluation criteria for value evaluation and finally introduce the evaluation of open-source software...
Data stream has attracted many researchers from various communities (network, database and data mining). There are a variety of techniques for solving the similarity matching in time series datasets. However, subsequence matching over data stream, finding those subsequences which are similar to a query sequence in a progressive and real-time fashion, is a challenging and novel problem due to the high...
