Generalized Hypercube Queueing Models with Overlapping Service Regions
Wenqian Xing, Shixiang Zhu, Yao Xie
Motivated by the operations of the Atlanta Police Department, where heavy workloads and staffing shortages increasingly require units to patrol across overlapping service regions,…
Quantifying Grid Resilience Against Extreme Weather Using Large-Scale Customer Power Outage Data
Shixiang Zhu, Rui Yao, Yao Xie +3
In recent decades, the weather around the world has become more irregular and extreme, often causing large-scale extended power outages. Resilience -- the capability of withstandin…
Non-stationary spatio-temporal point process modeling for high-resolution COVID-19 data
Zheng Dong, Shixiang Zhu, Yao Xie +2
Most COVID-19 studies commonly report figures of the overall infection at a state- or county-level. This aggregation tends to miss out on fine details of virus propagation. In this…
Multi-resolution spatio-temporal prediction with application to wind power generation
Zheng Dong, Hanyu Zhang, Shixiang Zhu +2
Wind energy is becoming an increasingly crucial component of a sustainable grid, but its inherent variability and limited predictability present challenges for grid operators. The…
Signal Processing Challenges and Examples for {\it in-situ} Transmission Electron Microscopy
Josh Kacher, Yao Xie, Sven P. Voigt +4
Transmission Electron Microscopy (TEM) is a powerful tool for imaging material structure and characterizing material chemistry. Recent advances in data collection technology for TE…
Data-Driven Optimization for Atlanta Police Zone Design
Shixiang Zhu, He Wang, Yao Xie
We present a data-driven optimization framework for redesigning police patrol zones in an urban environment. The objectives are to rebalance police workload among geographical area…
Data-Driven Optimization for Police Beat Design in South Fulton, Georgia
Shixiang Zhu, Alexander W. Bukharin, Le Lu +2
We redesign the police patrol beat in South Fulton, Georgia, in collaboration with the South Fulton Police Department (SFPD), using a predictive data-driven optimization approach.…
Spatial-Temporal-Textual Point Processes for Crime Linkage Detection
Shixiang Zhu, Yao Xie
Crimes emerge out of complex interactions of human behaviors and situations. Linkages between crime incidents are highly complex. Detecting crime linkage given a set of incidents i…
Sequential Adaptive Detection for In-Situ Transmission Electron Microscopy (TEM)
Y. Cao, S. Zhu, Y. Xie +4
We develop new efficient online algorithms for detecting transient sparse signals in TEM video sequences, by adopting the recently developed framework for sequential detection join…
