In this paper we present a novel clustering analysis method based on the Most Similar Relation Diagram (MSRD). MSRD is a diagram in which each datum of a dataset is linked to its most similar data. By cutting off some links in the diagram a certain number of clusters are formed. A compare of the MSRD method with hierarchical method is implemented. Clustering experiences using MSRD were done and the...
In this paper, a novel structure is derived for digital filter which is robust against the FWL errors. This structure, denoted as SIMP, is actually an improved version of the one reported in the work of Li et al. (2000) in terms of implementation efficiency and reducing quantization errors. The expression of transfer function sensitivity measure is derived for each structure. Two numerical examples...
Automatic citation metadata extraction is an important aspect of digital library development. The previous methods which using hidden Markov models to extract citation metadata mostly need label many training data manually. To save the high cost of labeling training data manually, this paper describes a method for citation metadata extraction using hidden Markov models. This method use unlabeled data...
Vibration signals of running piston compressor ordinarily include cyclical impulsion components. And they have the typical characteristics of super-Gaussian signals. When the compressor has weak local faults, it probably causes energy and phase changes of the vibration signals. However, the classic analytical methods which base on low-order statistics are often difficult to reflect the changes caused...
RSA is one of the most popular and widely used public key cryptosystems. In this paper, an application of low private exponent attack on it is presented. More precisely, let (N, e) be an RSA public key with corresponding private key d, then N can be factored provided that there exists a proper integer k such that ek is relatively small and dk mod phi(N) is small (or large) enough. Experiment shows...
In this paper, the piezoelectric properties of semiconducting nano structures have been investigated. The piezoelectric effect can be characterized via a nano-scale material testing system that utilizing microelectromechanical systems technology. The coefficients were measured by applying a voltage (field) and measuring the induced elongation (strain). It can be readily seen that the piezoelectric...
Using software agents as next generation flexible components and applying reuse technologies to rapidly construct agents and agent systems have great promise to improve application and system construction. Agent-based approach in software engineering is regarded as a promising technique in the development of software. First, a principle and method structured data object based for simplifying the complex...
