Large scale data process has emerged as an important issue for concerned researchers. By reusing calculation results, the efficiency of large scale data process can be improved greatly. This paper proposes an efficient data reusing strategy based on the data warehouse tool-Hive, which works on MapReduce framework. Since the intermediate calculation results have been stored in DFS by different jobs...
The quenched high-gain mode of semi-insulation photoconductive semiconductor switch (PCSS) is a new operating mode. It has many advantages over the traditional modes, such as ultrafast rise time (mainly determined by the laser), high power, short pulsewidth, ultrafast fall time (mainly determined by the carrier lifetime), and so on, making it possible to generate high-power ultrashort pulses. To approximate...
The medical image is widely used in medicine diagnosis for the science-sound qualitative and quantitative analysis. To achieve a clear image, the technology of the image segmentation is the key point. Therefore, this paper proposes a new image segmentation approach using the proportion of foreground to background method. Based on the traditional grayscale image segmentation and the edge detecting...
From functions and special characteristics of music education in the common institutions, the article discuss the mental health educational role of music education in the university, institutional strengthening of the art of music education measures and procedures.
Based on the finite connected graph, consider the dynamic game in which the players' strategies are related with their previous actions, i.e. the choice of the next state depends on all the states he or she has experienced other than the last state only. We show the theorem that there is always existing absolute equilibrium on the connected graph (with play payoff), and state the algorithm of absolute...
The influence of different time and different intensity on magnetic field treatment on delayed luminescence(DL) from mung beans leaves has been investigated by BPCL. The results indicate that on strength 225mT and 450mT for 10sand 20s the magnetic field can stimulate the body to stimulate the ultra-weak luminescence, the inhibition of the magnetic field is obviously and decaying in the exponential...
