Sensor networks for experience and ecology
(Massachusetts Institute of Technology, 2020)
Wetlands are critically important ecosystems, providing numerous benefits to the global environment. As cranberry farms in southeastern Massachusetts come out of production, many are undergoing active restoration with the ...
Embodied mathematics by interactive sketching
(Massachusetts Institute of Technology, 2020)
The language and formalization of mathematics historically evolved as an interplay between abstractions and their grounding in real world objects and events. The embodied mathematics philosophy posits that our mathematical ...
Studies in duality : discovering a dual catalytic amination reaction and investigating the origin of biphilicity in phosphacycles
(Massachusetts Institute of Technology, 2020)
First, the development of a novel C-H amination strategy using both a Cu(II) Lewis acid and an organic hydrogen atom transfer (HAT) catalyst to activate benzylic C-H bonds adjacent to aromatic azaheterocycles is described. ...
Polymers to modulate host-microbe interactions
(Massachusetts Institute of Technology, 2020)
Chemical interactions between microbes and hosts both support and destroy life. Recognition of self- and non-self, destruction of pathogens, and recruitment of symbionts are all largely mediated by multivalent interaction ...
The host heat shock response, viral immune escape and viral replication
(Massachusetts Institute of Technology, 2020)
Viral outbreaks follow human history, as illustrated by past and ongoing pandemics. The continuous nature of viral threats to global health is dictated by viral evolution, which enables the rise of resistance to therapeutic ...
Computational design and fabrication of portable MRI systems
(Massachusetts Institute of Technology, 2020)
In this work, I have developed techniques for designing portable MRI scanners and have applied them to three portable systems for brain imaging. I first describe the procedue for designing a portable, low-field MRI scanner ...
Essays on spillover effects in digital media
(Massachusetts Institute of Technology, 2020)
In this thesis, I address spillover effects in digital media across 3 different essays. In Chapter 1, I focus on estimating social spillovers in the consumption of online news. Exploiting regional rainfall as a natural ...
Advancement of closure relations for annular flow modeling in CFD
(Massachusetts Institute of Technology, 2020)
In Boiling water Reactors (BWRs), the presence of a liquid film in contact with the heated rod surface is crucial to ensure an efficient heat removal and prevent the threatening occurrence of dryout. The accurate prediction ...
Image segmentation for highly variable anatomy : applications to congenital heart disease
(Massachusetts Institute of Technology, 2020)
Automated segmentation of medical images can facilitate clinical tasks in diagnosis, patient monitoring, and surgical planning. However, current methods either rely on explicit correspondence detection, or use machine ...
Sigma shapes : parametric shape estimation for view and interaction planning
(Massachusetts Institute of Technology, 2020)
It is often useful for robots to actively build a model of an unknown 3D scene to enable tasks such as manipulation, mapping and object search. To do so requires choosing a representation to accumulate spatial knowledge, ...
