The paper introduce the debug module of ColdFire family MCUs, put emphasis on the BDM debug principle, then give the design method and schematic of BDM. This paper outlines the function of BDM debug system, and the in-depth analysis about the basic debug order is given. [ABSTRACT FROM AUTHOR]

Workpiece placing and removing for punching press operated by hand have low precision, low efficiency and poor security. The workpiece automatic placing and removing of punching press driven by pneunmtic is introduced in this paper. The overall structure and operating principle of manipulator are given. The pneumatic control and PLC program control are advanced to realize stepless speed regulation, overload protection and to complete complex actions easily. The substitute clamping jaw of manipulator is researched. The design shows the advantages such as simple structure, low cost, easy to operate and maintenance, high efficiency and reliability.

Similarity computing in patent information analysis is used widely. The traditional way of text similarity computing based on vector space model have two defects. One is that limitation put on word semantic by context was not considered enough, making it hard to effectively distinguish word semantic in diverse contexts. The other is that its use of dictionaries as foundation of similarity computing carried domain correlation, making it incapable of offering effective semantic comprehension in specific domain. Domain ontology is employed in this paper as the basis for text similarity computing, and sense disambiguation is applied to resolve the influence put on word semantic by context. Besides, maximum match of bipartite graph is used to carry out similarity computing. The experience result showed that the accuracy of this method enjoys improvements compared with the traditional way. [ABSTRACT FROM AUTHOR]

This paper aims at improving the performance of the SLIQ decision tree algorithm (Mehta et. al, 1996) for classification in data mining. An improvement over the SLIQ algorithm has been proposed to reduce the computational complexity. It was observed that the decision tree constructed using the proposed decision tree algorithm gave far better classification accuracy than the classification accuracy obtained using the SLIQ algorithm and the neural network classification technique.
