Developing automated tools to analyze synaptic calcium events
(Massachusetts Institute of Technology, 2020)
Synapses are the fundamental building blocks of the nervous system. Neuroscientists use electrophysiological approaches to measure synaptic release, which lack spatial resolution to measure synaptic transmission at the ...
Nonlinear analysis of topology-optimized scissor-like elements during deployment and structural performance analysis
(Massachusetts Institute of Technology, 2020)
Deployable structures, known for their flexibility and adaptability, have gained popularity in applications such as emergency shelters, aerospace structures, and sports facility roofs. One of many commonly used deployable ...
Accurate characterization of nanophotonic grating structures
(Massachusetts Institute of Technology, 2020)
Augmented reality waveguides are designed to have grating regions to in-couple, out-couple, and propagate light from a light engine to the user. This thesis develops two reliable systems to qualify manufactured waveguides. ...
Designing structures with tree forks : mechanical characterization and generalized computational design approach
(Massachusetts Institute of Technology, 2020)
Timber structures have seen a resurgence in structural design in recent years due to a desire to reduce embodied carbon in the built environment. While many of these structures use standardized or regular elements, the ...
Evaluation of the design space for reinforced concrete building components subject to blast loading
(Massachusetts Institute of Technology, 2020)
As the built environment becomes more complex, designers must consider extreme loading when it is necessary to anticipate structural response to rare hazards in addition to the expected loading conditions associated with ...
Spider web geometry inspires long span roof trusses
(Massachusetts Institute of Technology, 2020)
This research explores the methods and results used to learn from spider web geometries and implement them into a practical long span roof truss structure. Specifically, utilizing data and properties of spider webs found ...
Analysis and reproduction of geopolymer concrete
(Massachusetts Institute of Technology, 2020)
Geopolymers are inorganic polymers based on aluminosilicates that are produced from synthesizing pozzolanic compounds or aluminosilicate source materials with highly alkaline solutions. Geopolymer concrete is a stronger, ...
Learning about media Users from movie rating data
(Massachusetts Institute of Technology, 2020)
In this thesis, we study techniques of machine learning for media users who submitted movie ratings to the MovieLens dataset --- a project inspired by Sky UK's own business problems I encountered during my internship there. ...
A technical analysis of photogrammetry with reality capture
(Massachusetts Institute of Technology, 2020)
Photogrammetry is a useful process to quickly and accurately create 3D assets. Although the aesthetic quality of a reconstructed 3D model is ultimately the most important factor, other factors like total reconstruction ...
Using intelligent load adjustment to find feasible power flows in emergency situations
(Massachusetts Institute of Technology, 2020)
Economic forces guide power generation and distribution in power grids. In natural disasters and other emergency scenarios transmission lines can become overloaded and fail or power companies may preemptively blackout ...
