Technical Achievements 

Development and Application of State Assessment System for Urban Power Network based on the Big Data analysis 

According to the power grid, equipment and environmental information, this project is aiming at the research on dynamic evaluation of urban power grid transmission capacity, state evaluation, failure prediction, operation risk assessment, aid decision-making and related key technologies with the basis of big data analysis. At the meantime, this research is applied in the construction of the state evaluation system for the large urban power grid equipment, to improve the safety operation level of the power grid and equipment.  

Large-scale meteorological data processing and weather nowcast system: 

We have provided real-time meteorological data assimilation, severe weather nowcast, and customized service for Shenzhen Meteorology Bureau (SZMB). The research work of quantitative wind and rainfall estimation due to tropical cyclones has been incorporated into the Tropical Cyclones Integrated Operational Platform of SZMB, and has been frequently used in the meteorological information bulletin and weather consultation during typhoon season.  

3D video technology, Virtual Reality 

3D video processing and compression research has been conducted based on high-performance computing platform and optimization theory, with the goal to solve processing, storage, transmission, video quality assessment and other 3D video related issues. Video coding and visual perception are combined to extract human visual redundancy effectively, thus having improved the efficiency of video compression and enhanced the compression efficiency by 30%. In terms of application, An ultra-high-definition 3D live video and on-demand system have been developed.  And until now we have cooperated with enterprises in video, such as Skyworth, Phoenix Media and TEMOBI. 

Highly efficient analysis of genomic data at TB - PB scale  

A highly scalable genome assembly algorithm SWAP-Assembler was developed based on an asynchronous graph computing framework. Compared with the state-of-the-art tools such as Abyss, the analysis speed of is the fastest. The software is open sourced and has been downloaded about 500 times worldwide. 

Spatial-temporal Analysis Based On Large-scale Data  

Based on the spatiotemporal data collected by increasingly emerging sensors such as mobile phones, social media, and Internet of things as well as the high-performance computing technology, we focus on analyzing human spatiotemporal activity patterns in the information age, modeling spatiotemporal phenomena, and simulating spatiotemporal processes. Our research can help breakthrough the limitation of lacking large-scale human activity data sources for decades, and can offer critical methods and technologies for various application areas such as smart transportation, urban planning, public health, mobile Internet service, and big data service in a more general word.
