The data generated by scientific simulation, sensor, monitor or optical telescope has increased with dramatic speed. In order to analyze the raw data fast and space efficiently, data pre-process operation is needed to achieve better performance in data analysis phase. Current research shows an increasing tread of adopting MapReduce framework for large scale data processing. However, the data access...
In recent years, the developing speed of emerging technologies keep accelerating. Correctly understanding the future trend of technologies can help the government and enterprises formulate R&D strategies, and then seize the chance. Therefore, the research in Technology Trend has increasingly becomes a hotspot in technology management. First, the article puts forward four main aspects that technological...
The small-size unmanned helicopters have good application values in many areas. A beyond-visual-range controlled helicopter display system framework is built. By acquisition of signals of angle sensor, magnetoresistive sensor, GPS module, the flying information of pitch, incline, direction, position, etc. in helicopter is gotten in the system. The signals coded by single-chip microcomputer are wirelessly...
