Dispatching rule is an effective method for solving dynamic job shop scheduling problem in practical production. The development, classification and characteristics of dispatching rules were reviewed in this paper, and the research hotspots of dispatching rules including the selection and evaluation methods were summarized. The selection methods of dispatching rules were introduced in detail which...
Due to the inherent limitations of structure and dimensional, it is difficult to measure the surface roughness of micro-heterogeneous surface in deep hole. In this paper, the microscopic image of micro-heterogeneous surface is obtained by the long working distance lenses of digital microscopic camera, firstly. Thereafter, two artificial neural network models, which take microscopic image features...
The design of an efficient one-way hash function with good performance is a hot spot in modern cryptography researches. In this paper, a hash function construction method based on cell neural network (CNN) with hyper-chaos characteristics is proposed. The chaos sequence generated by iterating CNN with Runge-Kutta algorithm, then the sequence iterates with every bit of the plaintext continually. Then...
