Road transportation networks are a segment of society's critical infrastructure particularly susceptible to service disruptions. Traffic incidents disrupt road networks by producing blockages and increasing travel times, creating significant impacts during emergency events such as evacuations. For this reason, it is extremely important to incorporate traffic incidents in evacuation planning models. Emergency managers and decision makers need tools that enable rapid assessment of multiple, varied scenarios. Many evacuation simulations require high-fidelity data input making them impractical for rapid deployment by practitioners. Since there is such variation in evacuation types and the method of disruption, evacuation models do not require the …

Locality-Aware Dynamic Task Graph Scheduling, Jordyn Maglalang, Sriram Krishnamoorthy, Kunal Agrawal
All Computer Science and Engineering Research
Dynamic task graph schedulers automatically balance work across processor cores by scheduling tasks among available threads while preserving dependences. In this paper, we design NabbitC, a provably efficient dynamic task graph scheduler that accounts for data locality on NUMA systems. NabbitC allows users to assign a color to each task representing the location (e.g., a processor core) that has the most efficient access to data needed during that node’s execution. NabbitC then automatically adjusts the scheduling so as to preferentially execute each node at the location that matches its color—leading to better locality because the node is likely to make …

Sparse Encoding Of Binocular Images For Depth Inference, Sheng Y. Lundquist, Dylan M. Paiton, Peter F. Schultz, Garrett T. Kenyon
Computer Science Faculty Publications and Presentations
Sparse coding models have been widely used to decompose monocular images into linear combinations of small numbers of basis vectors drawn from an overcomplete set. However, little work has examined sparse coding in the context of stereopsis. In this paper, we demonstrate that sparse coding facilitates better depth inference with sparse activations than comparable feed-forward networks of the same size. This is likely due to the noise and redundancy of feed-forward activations, whereas sparse coding utilizes lateral competition to selectively encode image features within a narrow band of depths.

This project tested various wired and wireless topologies and benchmarked download speeds and quality for various types of media. For music, topology had a negligible impact. High quality video streams were impacted by latency introduced in the wireless topologies. Likewise, video game streaming, especially games of high graphical fidelity, were negatively impacted when streamed over a wireless network. For all types of media, a fully wired topology is recommended.

Data generalization (anonymization) is a widely misunderstood technique for preserving individual privacy in non-interactive data publishing. Easily avoidable anonymization failures are still occurring 14 years after the discovery of basic techniques to protect against them. Identities of individuals in anonymized datasets are at risk of being disclosed by cyber attackers who exploit these failures. To demonstrate the importance of proper data anonymization we present three perspectives on data anonymization. First, we examine several de-anonymization attacks to formalize the anatomy used to conduct attacks on anonymous data. Second, we examine the vulnerabilities of an anonymous nursing workforce survey to convey how …

The rise of Big Data Analytics has shown the utility of analyzing all aspects of a problem by bringing together disparate data sets. Efficient and accurate private record linkage algorithms are necessary to achieve this. However, records are often linked based on personally identifiable information, and protecting the privacy of individuals is critical. This work contributes to this field by studying an important component of the private record linkage problem: linking based on names while keeping those names encrypted, both on disk and in memory. We explore the applicability, accuracy, speed and security of three different primary approaches to this …

Dynamic Level-2 Cache Memory Locking By Utilizing Multiple Miss Tables, Andrew Louis Mocniak
Browse all Theses and Dissertations
Cache memory plays a vital role in a system's performance by acting as a buffer to quickly supply requested instruction/data blocks from the main memory to the central processing unit (CPU). Cache management techniques may increase or decrease a system's performance. The results vary from process to process, depending on how well optimized the cache management technique is for a particular process. The inclusion of level-2 (L2) cache locking has been shown in previous studies to be beneficial in increasing a system's performance. This is further improved upon through the inclusion of a miss table (MT), which keeps track of …

Wikimatcher: Leveraging Wikipedia For Ontology Alignment, Helena Brooke Mccurdy
Browse all Theses and Dissertations
As the Semantic Web grows, so does the number of ontologies used to structure the data within it. Aligning these ontologies is critical to fully realizing the potential of the web. Previous work in ontology alignment has shown that even alignment systems utilizing basic string similarity metrics can produce useful matches. Researchers speculate that including semantic as well as syntactic information inherent in entity labels can further improve alignment results. This paper examines that hypothesis by exploring the utility of using Wikipedia as a source of semantic information. Various elements of Wikipedia are considered, including article content, page terms, and …

Online social systems have emerged as a popular medium for people in society to communicate with each other. Among the most important reasons why people communicate is to share emotional problems, but most online social systems are uncomfortable or unsafe spaces for this purpose. This has led to the rise of online emotional support systems, where users needing to speak to someone can anonymously connect to a crowd of trained listeners for a one-on-one conversation. To better understand who, how and when users utilize these systems, and to evaluate their safety, this thesis offers a comprehensive examination of the characteristics …
