Detection of nucleic acid biomarker has particular importance for disease diagnosis and environmental safety. Yet the identification of low-abundant nucleic acids with unknown sequence remains extremely challenging. Previously we reported a strategy to identify short cDNA molecules using nicking endonucleases that create sequence-specific topographical labels visible by AFM. As such, the identity...
This paper describes effects of a large amount of artificial patterns to train an on-line handwritten Japanese character recognizer. In general, as more learning patterns employed for training pattern recognition systems, as higher recognition rate is obtained. In reality, however, the existing pattern samples are not enough, especially for languages of a large character set. Therefore, for on-line...
According to the management needs for scientific research projects, this paper propose a framework that combines data warehouse as the basis, OLAP, association rule, and apply it into the projects analysis of Science and Technology Bureau in Handan City. As a practical implementation of the framework, the Handan City Science and Technology Plan Project Implementation Survey System was developed. The...
The COW (copy-on-write) virtual block device supported by many virtual machine monitor (VMM) is very helpful for fast software deployment in large-scale virtualized computing environments. This paper presents an optimized block addressing approach for the COW block device driver in VMM and an on-demand software deployment scheme based on the optimization approach. With our approach, many small-sized...
The statistical & evaluation method in traditional combat simulation has betrayed its deficiencies in many aspects: data collecting, importing data to database, displaying statistical data, etc. The deficiencies have obstructed the further development of statistical & evaluation method in the combat simulation. Under the standard of extensible modeling & simulation framework (XMSF), web...
In this paper an edge detection algorithm base on wavelet transform with Gaussian filter was proposed. In this algorithm original images are firstly converted into gray images and then each pixel was analyzed using wavelet transform to find the local maximum of the gray gradient of each pixel along the phase angle direction and compared with a given threshold value, through which real edge can be...
