The growing size of Resource Description Framework (RDF) dataset requires RDF repository to be excellent scalable and highly efficient. Distributed and parallel processing model meets the urgent needs naturally. In this paper, we propose a scalable RDF store based on HBase, which is a distributed, column-oriented database modeled after Google's Bigtable.(More)
We propose a novel biometric recognition method that identifies the inner knuckle print (IKP). It is robust enough to confront uncontrolled lighting conditions, pose variations and low imaging quality. Such robustness is crucial for its application on portable devices equipped with consumer-level cameras. We achieve this robustness by two means. First, we(More)
This paper proposes an novel approach to extract the Region of interest (ROI) for palm print and inner knuckle print(IKP) from hand images captured from a digital camera. An new algorithm to detect candidate key points on hand region is described. Using the candidate key points a novel approach to locate the ROI of palm print and inner knuckle print is(More)
Inter-individual variability causing elevated signaling of receptor tyrosine kinases (RTK) may have hampered the efficacy of targeted therapies. We developed a molecular signature for clustering adult diffuse gliomas based on the extent of RTK pathway activities. Glioma gene modules co-expressed with NF1 (NF1-M), Sprouty (SPRY-M) and PTEN (PTEN-M) were(More)
We present a fast structure-based ASCII art generation method that accepts arbitrary images (real photograph or hand-drawing) as input. Our method supports not only fixed width fonts, but also the visually more pleasant and computationally more challenging proportional fonts, which allows us to represent challenging images with a variety of structures by(More)
In order to improve the detecting accuracy of the fast-detection device of the UHT(Ultra Heat Treated) box milk quality, the method of wavelet de-noising is applied to the free damped torsional vibration signals produced by the liquid milk box. And by getting the envelope demodulation using the Hilbert transform, the damping ratio of the system is finally(More)
