In the real world, uncertain data exist exoterically, as in many area of application, it is impossible to express data with uncertainty of one hundred percents. The uncertainty is inherent in these systems due to measurement and sampling errors, and resource limitations. The flexibility of XML data model allows a more natural representation of uncertain data compared with the relational model. The...
Ergonomic evaluation of manually controlled devices is an important means of testing a man - machine interface matching in manned space medicine and engineering research. It's one of the comprehensive evaluation method based on Delphi, AHP and Grey systems. This study proposed a mathematical model combining subjective weights and objective weights, evaluated manually controlled devices quantitatively,...
Data hiding is a type of information hiding technology. A data hiding method based on H.264 encoded video sequences is presented in this paper. The proposed method uses the parity of the coefficients after transformation and quantization to hide the desirable data. The digital data hidden by this approach can be recovered correctly by data recovering process and extracted directly from the encoded...
This paper presents a study on joint coding of video plus depth utilizing the correlation between video and depth. The Rate Distortion Optimization (RDO) technique has been employed in H.264 for intra prediction mode selection to achieve better coding efficiency. The proposed method considers the color video and depth video to compress jointly, which is based on the RDO mode decision algorithm and...
Binary Differential Evolution algorithm was proposed for discrete optimization problem. Firstly, a new operator, boundary-handling operator, was added to the original Differential Evolution to ensure each population generated by the mutation and crossover operator comply with the boundary constraints. Then a new hybrid coding Differential Evolution algorithm with mapping method was put forward to...
In this paper, an online layout algorithm for the one-dimensional cutting stock problems (ODCSP) has been proposed. The whole algorithm has been divided into two parts. The outer is the online controlled loop, and can continually transfer the given parameters to the inner loop; Partheno-genetic algorithm (PGA) has been applied to realize the layout optimization in the inner loop. In PGA, several strategies...
