According to the teaching problem of “Fundamentals of Information Technology” course, a strategy of Classified teaching based on computational thinking is brought forward. At the same time, it gives the design of Classified teaching task and the actual teaching cases.
Sea-ice has become a new kind of natural disasters, using remote sensing technology to achieve the sea-ice has been very mature monitoring technology, but for different satellite data have different monitoring method, this paper based on the Sea-ice spectral characteristic curve, and using HJ 5 temporal data during January 2010 to February 2010 in BoHai nearby Tianjin area, monitor the sea-ice development...
Because the changing frequency of extreme climate events generally has profound impacts on our living environment, research of the related topic has received much attention in social sciences. Based on the daily data collected from 753 meteorological stations in China during 1961-2005, the present work studies the relationship among some extreme climate indices, that is, FEP(frequency of extreme precipitation),...
The analysis literature about the series resonant converter for Induction heating based on quasi-sliding mode variable structure control, The mathematic model of series resonant converter for Induction heating are established, including the discrete-time integrator switch surface and the control law of sliding mode which is design in the paper not only hold the high robustness, but also highly reduce...
This paper studies the current personalized information recommendation services, content-based filtering and collaborative filtering as the two basic methods for information filtering is widely used. Since there are two kinds of filtering are limited, design and implementation of these limitations, a new information filtering system. The information filtering system used is based on the combination...
Objective: To investigate the effect of bcr-abl fusion gene on CML cell apoptosis. Methods: Apoptosis of ex-vivo cultured K562 cells were observed after exposure to synthetic 18 mer antisense oligodeoxynucleotide complementary to the bcr-abl junction (b3a2). Results: Apoptosis of K562 cells was significantly increased associated with inhibition of bcr-abl expression. Conclusion: bcr-abl fusion gene...
