Dispatching logic, corridor simulation, and train following algorithms to quantify the benefits of virtual and moving block control systems on North American freight railroad mainlines
… evaluating the effectiveness of virtual and moving block railway control systems on North American freight railroad mainline corridors. Virtual and moving block control systems are one potential strategy for improving mainline operations such that corridors currently operating at capacity can …

Interframe image coding with three-dimensional gradient motion estimation
… either the pixel motion vectors directly on the moving block (pixel motion estimation) or calculate the block motion vector from the pixel motion vectors (block motion estimation). For both methods, the differences between the prediction block and the moving block are vector quantized.

Statistical analysis of networks with community structure and bootstrap methods for big data
… community detection literature. We propose a blockmodel for heterogeneous networks with community structure, and introduce a heterogeneous spectral clustering algorithm for community detection in heterogeneous networks. Theoretical properties of the clustering algorithm under the proposed …

Statistical issues and developments in time series analysis and educational measurement
… dependent time series. It is well known that the moving block bootstrap method produces an inconsistent estimator of the distribution of the normalized sample mean when its limiting distribution is not normal. The subsampling method of Hall, Lahiri and Jing (1998) produces a consistent estimator …

Network Analysis of the Financial Sector: A Comprehensive Perspective with Adaptive Joint LASSO Method
… shocks in financial networks. Integrating a moving-block bootstrap method (MBB) into the framework, I can investigate how the observed shocks transform the financial networks. 3. My conceptual contribution is that I characterize and analyze illiquidity networks. The liquidity concerns are …

Three essays in econometrics
This thesis consists of three essays. The first essay investigates the issue of local misspecification in instrumental variable models. We show that conventional tests often fail to give accurate inferences when the exogeneity conditions of some instruments are mildly violated. The sizes of those …
