Redesigning the Structure and Access Paths of Databases for Effective and Efficient Query Processing

Creator:: Ghadakchi, Vahid
Abstract:: Many database users are not familiar with formal query languages, the concept of schema, or the exact content of their database. Thus, it is challenging for these users to formulate their information needs over semi-structured and structured databases. To address this problem, researchers have proposed usable query interfaces over which...

Design for Clean Technology Adoption: Application of Discrete Choice Analysis and the Theory of Planned Behavior for Development Engineering

Creator:: Pakravan, Mohammad H.
Abstract:: Clean technologies can address multiple challenges associated with climate change, environmental protection, and human health. However, the impact desired by introduction of such technologies is achievable only if new options effectively replace inefficient, conventional practices. This ‘design for adoption’ requires understanding of user motivations, associated beliefs, context of use, and...

Learning to Estimate Multi-Relation Aggregation Functions

Creator:: Jadhav, Rashmi Suresh
Abstract:: Multi-relation aggregation queries process the join operator before computing the aggregation function. This join is arguably the most costly operation since traditional join algorithms spend majority of their time trying to join the parts of the relations that do not generate any output tuples. This causes slow response times with...

Digital Solutions for Analog Shortcomings in Delta-Sigma Analog-to-Digital Converters

Creator:: Mirzaie, Hossein
Abstract:: Portable, high power efficiency communication devices is a growing market in the semiconductor industry. Analog-to-digital converters (ADC) are key interface that are used to digitize the sensed information. Recently, digital techniques have been proposed to improve analog building block power efficiency in sub-micron technologies. This research focuses on mixed signal...

Development and Trial of a Usability Testing Protocol for Biomass Cookstoves : An Interdisciplinary Approach

Creator:: Moses, Nicholas D.
Abstract:: Improved cookstoves have been designed and disseminated for several decades in an effort to address the human health and environmental issues caused by the inefficient, traditional biomass cooking and heating methods used by 40% of the world’s people. Engineers and designers working on these improved stoves have tended to focus...

Decentralized Multiagent Coordination for Connected and Autonomous Vehicle Routing in Congested Networks

Creator:: Mostafizi, Alireza
Abstract:: In 2017, the cost of congestion in the United States was around 305 billion dollars, and city-dwellers, on average, lost 1400 dollars while sitting 42 hours in traffic jams. Aiming for better mobility and more efficient utilization of the transportation network, emerging connected and autonomous vehicle (CAV) technologies and their...

Seismic assessment of unreinforced and retrofitted masonry buildings using Applied Element Method (AEM)

Creator:: Soti, Rajendra
Abstract:: A significant number of Unreinforced Masonry (URM) buildings exist in the Pacific Northwest region of the United States of America that is a region of high seismicity, which could be subjected to both crustal and subduction zone earthquakes. The catastrophic and brittle failures associated with URM buildings in the past...

Effective Bonding Parameters for Hybrid Cross-Laminated Timber (CLT)

Creator:: Larkin, Blake
Abstract:: Cross-laminated timber (CLT) is a massive engineered wood product made of orthogonally bonded layers of solid-sawn lumber, and is intended for roof, floor, or wall applications. Although it was developed in Europe in the early 90s, CLT is relatively new to North America. CLT products must be certified for structural...

Network Coding, Random Matrices, and Their Applications to Communication Systems

Creator:: Nguyen-Huu, Duong
Abstract:: In this work, we study network coding technique, its relation to random matrices, and their applications to communication systems. The dissertation consists of three main contributions. First, we propose efficient algorithms for data synchronization via a broadcast channel using random network coding. Second, we study the resiliency of network coding...

Location Privacy-Preserving Strategies for Secondary Spectrum Use

Creator:: Grissa, Mohamed
Abstract:: The scarcity of wireless spectrum resources and the overwhelming demand for wireless broadband resources have prompted industry, government agencies and academia within the wireless communities to develop and come up with effective solutions that can make additional spectrum available for broadband data. As part of these ongoing efforts, cognitive radio...
