This paper discusses the problem of optimal motion planning for a rigid underactuated spacecraft. Firstly, we derive the dynamic and kinematic equations of the spacecraft, and for given initial and terminal states, the performance index to be optimized is selected as minimizing the total fuel consumption. Moreover, the control input saturation restriction is transformed into an inequality constraint...
Scalable to lossless (SLS) audio coding is a state-of-art audio coding technique that has been adopted as MPEG scalable audio coding tool. To realize bit-plane refinement, this technique employs bit-plane arithmetic coding for lossless entropy coding, and Laplacian distribution is used to model the input data to realize high compression efficiency. In this paper, bit-plane probability is analyzed...
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...
