Scalable manufacturing of hierarchical nanostructures for thermal management
(Massachusetts Institute of Technology, 2012)
The focus of this thesis is a new simple and scalable process to make surface coatings that have multiple length scales, or hierarchical features. Typically, the formation of hierarchical structures involves multiple steps ...
Experiments in fluid spreading in the partial wetting regime
(Massachusetts Institute of Technology, 2014)
The spread of a fluid on a flat surface has been the subject of intense research for a number of decades, having importance in surface treatment technologies, porous media flow, and common naturally ocurring phenomena. In ...
Prediction of velocity distribution from the statistics of pore structure in 3D porous media via high-fidelity pore-scale simulation
(Massachusetts Institute of Technology, 2017)
Fluid flow and particle transport through porous media are determined by the geometry of the host medium itself. Despite the fundamental importance of the velocity distribution in controlling early-time and late-time ...
AdaptDB : adaptive partitioning for distributed joins
(Massachusetts Institute of Technology, 2017)
Big data analytics often involves complex join queries over two or more tables. Such join processing is expensive in a distributed setting both because large amounts of data must be read from disk, and because of data ...
Design and analysis of penetrator probes for planetary science applications
(Massachusetts Institute of Technology, 2017)
Penetrator probes emplace by impact into a solid medium, carrying scientific instrumentation to fulfil specified post-impact mission objectives. They have been used successfully for multiple terrestrial applications, but ...
Design space exploration and optimization using modern ship design tools
(Massachusetts Institute of Technology, 2014)
Modern Naval Architects use a variety of computer design tools to explore feasible options for clean sheet ship designs. Under the Naval Sea Systems Command (NAVSEA), the Naval Surface Warfare Center, Carderock Division ...
Optimizing flow rate and bacterial removal performance of ceramic pot filters in Tamale, Ghana
(Massachusetts Institute of Technology, 2015)
Pure Home Water (PHW) is an organization that seeks to improve the drinking water quality for those who do not have access to clean water in Northern Ghana. This study focuses on the further optimization of ceramic pot ...
A direct-write thick-film lithography process for multi-parameter control of tooling in continuous roll-to-roll microcontact printing
(Massachusetts Institute of Technology, 2014)
Roll-to-roll (R2R) microcontact printing ([mu]CP) aims to transform micron-precision soft lithography in a continuous, large-scale, high-throughput process for large-area surface patterning, flexible electronics and ...
Building compressed sensing systems : sensors and analog-to-information converters
(Massachusetts Institute of Technology, 2012)
Compressed sensing (CS) is a promising method for recovering sparse signals from fewer measurements than ordinarily used in the Shannon's sampling theorem [14]. Introducing the CS theory has sparked interest in designing ...
Automated synthesis of low-rank stochastic dynamical systems using the tensor-train decomposition
(Massachusetts Institute of Technology, 2016)
Cyber-physical systems are increasingly becoming integrated in various fields such as medicine, finance, robotics, and energy. In these systems and their applications, safety and correctness of operation is of primary ...
