The 9th Conference on mathematical programming of China has been held in the city of Hangzhou, Zhejiang Province, China, April 21-24, 2012. This is the 9th of the mathematical programming conference series. Prof. Gao Suixiang gave a talk named “Mathematics in wireless communication network optimization”.

 

Nowadays, both the scale of network and the number of users of GSM networks in China have been the largest of the world. As the scale of networks and users expands, the network resources available are becoming less and less, making it the bottleneck of enlarging the GSM networks capacity. The objective of GSM/3G networks optimization is to find out the factors influencing the quality of the networks, adjust the network configuration and maintain the communication networks in steady and effectively states so as to improve the QoS for users. In this talk, Prof. Gao Suixiang studies the optimization of GSM/TD-SCDMA networks in Beijing and Guangzhou. First, he proposes a new adaptive propagation model to obtain a high-precision coverage map of field intensity. Then he builds a traffic matching model by utilization of Neighbor Cell Support (NCS) and Measurement Report (MR) data, obtaining a high-precision traffic map. On the basis of above work, he presents a nonlinear non-smooth multi-objective optimization model for optimization of antenna parameters and QoS of communication networks.

Dr. Yan Ma, the assistant professor of Cornell University, visited our department on the invitation of Professor Sanguo Zhang of the mathematical department on April 20 and gave a lecture on “Recent Developments in Multivariate Meta-analysis and a Robust Approach Based on the Theory of U-statistic”.

 

The lecture was held by Professor Sanguo Zhang. Teachers and students from different departments attended this lecture. In the lecture, Dr. Yan Ma introduced the background, development and current situation of Meta-analysis and his latest research findings in this field with U statistics. At last, he had a discussion with the audience.

 

Dr. Yan Ma received his Ph.D. in Statistics from the University of Rochester in 2008 and now works in the Division of Biostatistics and Epidemiology in the Department of Public Health at Weill Medical College of Cornell University. Dr. Ma’s research interests in statistical methodology center on inference for instrument reliability and rater agreement, nonparametric estimation and inference, observational studies, causal inferences, meta-analysis, complex survey data analysis, longitudinal data analysis, and missing data problems.
