    Nowadays, directory-based cache coherence protocols have been the best choice in designing large-scaled CC-NUMA systems. Directory contains the shared information of all memory blocks in system. The number of copies of shared data in system and their distributing characteristics are deeply influenced by the characteristics of application programs. In this paper, a Markov chains model is built for ... View full abstract»

    This paper proposes a novel algorithm for load balancing in the parallel and distributed systems. Firstly, almost all jobs are organized into the standard job combinations, each of which consists of one to four jobs. Then they are assigned to the machines according to the assignment algorithm for job combinations, which is a special integer partition algorithm. The maximum error between the optima...

    The synchronization between audio and video during their transmission and play out has become one of key issues of Internet multimedia applications. In this paper, a new scheme for synchronized coding of audio and video is proposed. In the encoder, audio bits are embedded into transformed coefficients of video as hiding signal, and then the hybrid information is encoded simultaneously. In the deco... View full abstract»

    In the novel system for off-line signature verification, both static and pseudodynamic features are extracted as original signal, which is processed by discrete wavelet transform (DWT) for the purpose of enhancing the difference in time domain between a genuine signature and its forgery. The verification scheme is achieved by combining the proposed fuzzy net output in each sub-band level. In addit... View full abstract»

    Pulse coupled neural network (PCNN) has gained widely research as a new artificial neural network. It derives directly from the studies of the small mammal's visual cortex. The peak-and-valley filter can keep the details of image sufficiently if the density of noise is low enough. But for the image that is badly contaminated with noise, the effect of the peak-and-valley filter is inadequate. To ov... View full abstract»

    Slice is one of the major operations in on-line analysis processing which has played an important role in the application of decision support. Based on data cube, by mining the maximum singular value of the slices, a method was proposed in this paper to extract the inner rules of movement. Algebraic theories proved that it is feasible. And the numerical experiment also demonstrated that it is effi... View full abstract»

    Parzen windows estimation is one of the classical non- parametric methods in the field of machine learning and pattern classification, and usually uses Gaussian density function as the kernel. Although the relation between the kernel density estimation (KDE) and low-pass filtering is well known, it is vary difficult to setting the parameters of the other kinds of density functions.

    A large collection of formal concepts can be a hedge of the application of formal concept analysis and is not directly comprehensible for a user. It is thus an important task to develop methods which help to overcome the problem of large number of extracted formal concepts. This paper proposes concept hierarchies learning for getting more concise concept representation method using fuzzy formal co... View full abstract»

    This paper is concerned with classification for a class of second-order singular equations on time scales. Firstly, we construct a sequence of circles. These circles are nested and converge to a limiting set. By the different cases of the limiting set, we can obtain the number of linearly independent square delta-integrable solutions of the equations. It follows from this number, we divide equatio...
