Bit-plane probability of data is a useful characteristic for many applications, such as entropy coding. Its value may vary according to the distribution of the data. In this paper, the bit-plane probability of data with generalized Gaussian distribution is analyzed. By studying the statistical characteristics of the sources and the bit-plane probability for Laplacian distribution, an approximated...
A High-frequency and micro-positioning mechanism for the middle-convex and varying ellipse piston machining is developed in this paper. To satisfy the complex profile and high accuracy requirement in piston machining, it uses rolling guide and elastic block to support the linear motor. This mechanism has high rigidity, small damping and high dynamic accuracy. Considering the characteristic of high-frequency...
Often, two music pieces may be rhythmically similar, despite being composed of different instrument sets. These instrument sets though acoustically different, play similar rhythmic roles and hence project similar rhythmic feel. Also, the accompaniment music, besides the dominant drums or brass, may influence one's perception of the similarity/dissimilarity of two music pieces. These motivate our study...
The paper addresses an information embedding audio coder based on the MPEG-4 scalable lossless coding system. By replacing the last part of the bitstream in each frame with a fixed amount of embedded information, the proposed truncator is able to truncate the bitstream without affecting the embedded information. Evaluation results show that the bitstream with the proposed technique is able to carry...
For the low recognition degree of essential protein based on topological parameter, the correlation between the essentiality of proteins and their main topological parameters is analyzed and the nature of the essentiality-judgment ability of the parameters is explored firstly. Then, the mutual information of essential node these parameters contain is brought out in virtue of their correlation, based...
