Essays in different text genres have different ideas and writing method. Prediction the text genres firstly will help get a better accuracy when predicting the success of literary or finding the beautiful words and sentences in the essay. And it will help set a different standard for different text genres when scoring the writing by computer. Words and structure can be effective in discriminating...
General purpose GPU's (GPGPU) appearance made it possible that heterogeneous computing can be used by human beings. And it's also produce a reform for GPU's general purpose computing and parallel computing. Heterogeneous Systems has been adopted by large-scale of high-performance computers. Nowadays, fault tolerance technique is necessary among these large-scale kinds of scientific computing, but...
Heterogeneous parallel systems have become popular in general purpose computing and even high performance computing fields. There are many studies focused on harnessing heterogeneous parallel processing for better performance. However the energy optimization for heterogeneous system has not been well studied. Owing to the differences in performance and energy consumption, the energy optimization technique...
Dose calculation plays an important role in radiation treatment planning system. In this paper, collapsed cone convolution method for photon dose calculation was investigated. Based on coordinate transformation and fast ray tracing technology, dose was calculated according to the collapsed cone convolution algorithm on Visual C++ 6.0 platform, and compared with that calculated by DOSXYZnrc Monte Carlo...
This paper presents a robust watermarking algorithm based on regression of SVM. The host image is divided into two parts firstly. The first one is to train SVM using features including four relationships between the neighbor pixels, and the other part is to embed watermarks. The center pixels of image blocks are compared with the predicted pixels of trained SVM, and then modified to embed watermarks...
