Experiments and a model of pilot system failure detection during simulated Lunar landing
(Massachusetts Institute of Technology, 2014)
Future complex systems, such as those found in piloted aircraft and spacecraft, will undoubtedly utilize significant automation to enhance pilot capabilities and enable novel mission scenarios. Off-nominal conditions may ...
Development of a high-precision ADS-B based conflict alerting system for operations in the airport environment
(Massachusetts Institute of Technology, 2014)
The introduction of Automatic Dependent Surveillance - Broadcast (ADS-B) as the future source of aircraft surveillance worldwide provides an opportunity to introduce high-precision airborne conflict alerting systems for ...
Airport surface traffic optimization and simulation in the presence of uncertainties
(Massachusetts Institute of Technology, 2014)
Surface traffic congestion causes significant taxi delays and long queues for takeoffs at busy airports, increasing operational and environmental costs. These impacts may be mitigated by optimizing runway and taxiway ...
Structure and function of the Influenza membrane protein M2 by magic angle spinning NMR and dynamic nuclear polarization
(Massachusetts Institute of Technology, 2014)
Determination of the 3D structure of membrane proteins is a frontier that is rapidly being explored due to the importance of membrane proteins in regulating cellular processes and because they are the target of many drugs. ...
High field DNP and cryogenic MAS NMR : novel instrumentation and applications
(Massachusetts Institute of Technology, 2014)
Solid State Nuclear Magnetic Resonance (ssNMR) spectroscopy has blossomed over the last two decades. As ssNMR is progressively applied to more challenging systems, the sensitivity remains one of its major limiting factors. ...
Microstructural manipulation and architecture design of carbon-based electrochemical systems
(Massachusetts Institute of Technology, 2014)
Carbon materials are important in electrochemistry. The often cited advantages of carbonaceous materials for electrochemical applications include wide potential working windows, tunable electrocatalytic activity for a ...
Automated feedback in flow for accelerated reaction screening, optimization, and kinetic parameter estimation
(Massachusetts Institute of Technology, 2015)
With the cost to discover and develop a drug now estimated to exceed $2 billion, the pharmaceutical industry is in search of innovative and cost-effective ways to reduce process footprint, minimize lead times, and accelerate ...
Power and limitations of convex formulations via linear and semidefinite programming lifts
(Massachusetts Institute of Technology, 2016)
Convex relaxation methods play an important role in mathematical optimization to tackle hard nonconvex problems, and have been applied successfully in many areas of science and engineering. At the heart of such methods ...
Essays in political economy
(Massachusetts Institute of Technology, 2018)
This thesis consists of three chapters on political economy. Each chapter explores the effects of a change to the equilibrium of a given market. In the first chapter, Jon Weigel and I study a randomized controlled trial ...
Investigation of spine loading to understand vertebral fractures
(Massachusetts Institute of Technology, 2015)
Vertebral fractures are the most common complication of osteoporosis and are associated with significant pain, height loss, disfigurement, respiratory impairment, depression, and decreased life span. Despite the high ...
