Quantitative Framework to Design Services with Intrusion Tolerant QoS

Nguyen, Quyen Luong (2014-05)

Large software systems can be designed as a set of loosely coupled services interacting with each other; simple services can be composed to form more complex services. But, for services to be usable in production, they ...
Query Consolidation: Interpreting Queries Sent to Independent Heterogenous Databases

Acar, Aybar C. (2008-08-14)

This dissertation introduces the problem of query consolidation, which seeks to interpret a set of disparate queries submitted to independent databases with a single “global” query. The problem has multiple applications, ...
Randomization Tests for Regression Models in Clinical Trials

Parhat, Parwen (2013)

In this dissertation, we apply randomization tests in the context of regression models to detect treatment effects for clinical trial data. This application allows us to compute randomization tests for a wide variety of ...
A Rate-based Congestion Control Overlay System

Cao, Lianjie (2011-08-22)

Traditional TCP/IP networks provide a best effort delivery service which places the complexity of congestion control in the end hosts, leaving the network relatively simple. It is well-known that the performance of the TCP ...
Realizing Cyber Resilience with Hybrid Intrusion Tolerance Architectures

Nagarajan, Ajay (2017)

The current approach to security is based on perimeter defense and relies on firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS). These systems require a priori information about attack ...
Receiver Design for Massive MIMO Wireless Systems

Xu, Ping

Massive multiple-input multiple-output (MIMO) systems that employ a large number of antennas at both receivers and transmitters have been widely considered for adoption in next generation (5G) wireless networks. The ...
Recommending Service Repairs

Church, Joshua (2014)

An increasing amount of data is provided by information services: Programs
Recommending Temporally Relevant News Content Using Implicit Feedback Data: A Tag-Based Approach

Muralidhar, Nikhil

News has in this day and age, transformed primarily into a digital format with leading newspapers and news agencies having a significant online presence. The speed at which news reaches the reader notwithstanding, the ...
Reconstructing Neuronal Network Dynamics Using Data Assimilation

Hamilton, Franz William (2015)

Understanding the dynamics of the in vivo brain under normal and diseased states is one of the great challenges of modern scientific study. The overall complexity and dimension of the brain though can make this problem ...
Recursive Parameter Estimation for Continuous-time Bivariate Markov Chains

Li, Zhuxuan (2014-10-21)

A continuous-time bivariate Markov chain comprises a pair of continuous-time random processes which are jointly Markov. One of the two processes is an underlying process while the other is assumed observable. An important ...
Regression Models for Predicting Rail Transit Ridership at the Station Level

Hartig, Daniel

Methods for predicting ridership for future urban rail systems or extensions often have poor accuracy. One study shows that predicted ridership is overestimated by about 50%, on average, for a broad sample of urban rail ...
Regularized Learning in Multiple Tasks with Relationship

Charuvaka, Anveshi (2015)

Supervised classification is a sub-task of machine learning where the goal is to infer a classification function using labeled data. A vast amount of research has been conducted in this area addressing various classification ...
Reliability Management Techniques for Energy-Aware Multiprocessor Real-Time Systems

Haque, Mohammad Atiqul (2016)

Energy conservation and reliability management are important design objectives for real-time embedded systems. The existing solutions that simultaneously consider energy and reliability dimensions are mostly developed for ...
Reliable Bulk Data Dissemination in Sensor Networks

Huang, Leijun (2007-12-18)

A wireless sensor network consists of a large number of resource-constrained sensor nodes that are self-organized into a multi-hop network and cooperate on a single task. In many situations, sensor networks need to run ...
Rendered 3D Graphical Exploration of Multivariate Data Based on Truncated Octahedron Binning, Gray-Level Image Processing and Cognostics

Zhang, Zijing (2017)

This dissertation develops 3D visualization methods for exploratory analysis of
Representing and Visualizing Articulated Movement

Revelle, Matthew (2009-07-25)

This thesis develops a representation and system of operations for articulated limb movement which can be used to describe both specific and general movements. A movement primitive in the representation can be described ...
Resisting Reliability Degradation through Proactive Reconfiguration

Cooray, Deshan (2010-11-02)

Situated software systems are an emerging class of systems that are predominantly pervasive, embedded, and mobile. They are marked with a high degree of unpredictability and dynamism in the execution context. At the same ...
Revealed Path Choice Behavior and Network Pruning for Efficient Path Finding

Zhou, Xi (2014-05)

This dissertation addresses two separate problems related to transportation networks. In the first part, route choice behavior revealed from real world trips is studied. In part two, efficient pruning of large transportation ...
Robust and Reusable Methods for Shepherding and Visibility-Based Pursuit

Vo, Christopher Alexander (2014)

Algorithms for the control and monitoring of swarms of moving agents are important in a wide variety of real and virtual applications such as crowd control, livestock herding, and decentralized robot control architecture. ...
Robust Bias Mitigation for Localization in Wireless Networks

Bhagwat, Nikhil (2010-05-20)

Localization of a wireless device or a sensor node has been a problem of great importance in recent years. Location services are becoming an essential part of the traditional wireless networks as well as the wireless ...
