Methods and applications for space-time data
Spatial and spatio-temporal data are presented in a variety of forms and require a unique set of techniques to analyze. The goal of such analyses is often to estimate the spatial and/or temporal dependency structures of the underlying random field. This estimation in turn can then be used to make …

Real time data acquisition for load management
Demand for Data Transfer between computers has increased ever since the introduction of Personal Computers (PC). Data Communicating on the Personal Computer is much more productive as it is an intelligent terminal that can connect to various hosts on the same I/O hardware circuit as well as execute …

Nonparametric and semiparametric methods for interval-censored failure time data
Interval-censored failure time data commonly arise in follow-up studies such as clinical trials and epidemiology studies. By interval-censored data, we mean that the failure time of interest is not completely observed. Instead, we only know that it belongs to a certain interval. For the analysis of …

Estimating post-disaster traffic conditions using real-time data streams
… models with a traffic model and traffic sensor data. Using the earthquake characteristics as an input to the traffic model, the traffic conditions are sequentially estimated given traffic sensor measurements using an ensemble Kalman filter. The proposed algorithm is tested through numerical …

Secure Minimum Time Data Collection (SMTDC) protocol for wireless sensor networks
Recent work has shown that a mobile data collector moving along a predefined trajectory can improve the real-time data collection duration and efficiency in wireless sensor networks (WSN). Due to the fixed trajectory and limited communication range, data collection is conducted using a many-to-one …

Machine learning and coresets for automated real-time data segmentation and summarization
In this thesis, we develop a family of real-time data reduction algorithms for large data streams, by computing a compact and meaningful representation of the data called a coreset. This representation can then be used to enable efficient analysis such as segmentation, summarization, …
