Redesigning the memory hierarchy to exploit static and dynamic application information
(Massachusetts Institute of Technology, 2019)
Memory hierarchies are crucial to performance and energy efficiency, but current systems adopt rigid, hardware-managed cache hierarchies that cause needless data movement. The root cause for the inefficiencies of cache ...
Sensing lights : transforming street lights into a networked urban knowledge platform
(Massachusetts Institute of Technology, 2020)
This work is subdivided into three academic papers that together form a coherent exploration of the phenomena of intelligent street lights and their potential applications as a new type of digital urban infrastructure. In ...
Essays on workplace practices in different institutional settings
(Massachusetts Institute of Technology, 2020)
This dissertation consists of three essays investigating how organizational policies operate within different institutional contexts and in the face of migration, demographic shifts, and globalization. The first essay ...
Design tools and mechanisms for progressive cavity pumps
(Massachusetts Institute of Technology, 2019)
This thesis presents tools to design progressive cavity pumps (PCPs), with an emphasis on low-viscosity fluids. These models indicate that high speed operation can increase sealing performance, decrease pump size, and ...
A new approach to predicting departure from Nucleate Boiling (DNB) from direct representation of boiling heat transfer physics
(Massachusetts Institute of Technology, 2020)
Accurate prediction of the Departure from Nucleate Boiling (DNB) type of boiling crisis is essential for the design of Pressurized Water Reactors (PWR) and their fuel. Recent advances in the instrumentation of boiling ...
Topological quantum optics in two-dimensional atomic lattices
(Massachusetts Institute of Technology, 2019)
A key goal in quantum science is to build quantum systems that are robust to disorder and experimental imperfections. The application of topology to quantum physics is one of the most promising avenues towards achieving ...
Atomic engineering on 2D materials using electron irradiation and chemical protection
(Massachusetts Institute of Technology, 2020)
Controlling the exact atomic structure is an ultimate form of engineering. Atomic manipulation and atom-by-atom assembly can create functional structures that are hard to synthesize chemically. Defects with one- or ...
Learning from clinical health data for real-time decision support in emergency department care of sepsis
(Massachusetts Institute of Technology, 2019)
The emergency department (ED) is the first point of contact with clinicians for most patients with acute illnesses. Early identification along with appropriate interventions (including procedures, medications, and triaging ...
A systems analysis of scheduled air transportation networks
(Massachusetts Institute of Technology, 1979)
Molecular beam study of van der Waals molecules: spin-rotation interaction in potassium-argon.
(Massachusetts Institute of Technology, 1974)
