Research Experiences:
(1). 2011-2013, I chaired the project funded by “National Nature Science Foundation of China: Concurrent Tasks Oriented QoS-Aware Geospatial Information Services Optimization Composition Method”. In this project, I was responsible for analyzing completion and cooperation behavior of tasks under concurrent situation and design a novel optimization composition method for geospatial information services.
(2). 2011-2014, I co-chaired the project funded by “National Nature Science Foundation of China: Video-Based Traffic Incident Automatic Detection Method under Complex Situation”. I was responsible for 3D rebuilding from sequences image and automatically extracting information from complexity traffic accident. Future, we are ready to integrate this system with other highway information systems by services-oriented architecture and Sensor Web Enablement to implement the sensors, data, processing services (Software as a service) being seamless linked.
(3). 2006-2009, I took part in the project funded by “The High Technology Research and Development Program of China: Task-Oriented Sensor Resource Organize Mechanism and Geospatial Information Services Methods”, as core researcher. The research including:
1) Sensor resources description model and plan method.
2) Hierarchical semantic constraint model for focused geospatial information
A hierarchical uniform semantics description model with four levels which includes user semantic constraints, data semantic constraints, processing service function semantic constraints and process service quality semantic constraints;
The base of semantic reasoning in service discovery, selection and composition.
3) Adapt to user requirement
Choose a most similar service chain by user requirements relatedness analysis;
Fast reconfiguring services chain by local revising based on reuse knowledge about similarity, already solved problems successfully.
4) Robust optimization in dynamic environment
Analyze the influence of QoS perturbation including QoS preference, QoS constraints, and services QoS on service chain;
Set up a robust optimization model to keep service composition optimal solution more stable.
5) Concurrent tasks optimization
A non-cooperative game based mathematics model is proposed to analysis competition relationship between concurrent tasks;
Set up an iteration algorithm converging to Nash equilibrium, which maximizing all task’s utilization under multi-task conflict condition.
(4). In 2009-2010, I took part in the project funded by “The High Technology Research and Development Program of China: the Foundation theory of approach-and-landing visual navigation in complexity environment”, as a researcher. In this project, I was responsible for the 3D modeling and visual theory and method for the complexity environment including terrain environment, atmosphere environment and electromagnetism environment.
(5). 2009-2010, I take part in the project funded by “The National High Technology Research and Development Program of China – “Three Dimension Modeling and Analysis in Geospatial Information, Theory and Applications”, as a main researcher. My duty is listed as following:
TIN and CTIN generation and dynamic modification from a huge number of data
View-depend continuous LOD algorithm
Highway line type based dynamic subsection and large-scale scenes management and schedule
(6). 2007-2008, I took part in the project funded by “The National High Technology Research and Development Progr
