Rotation of a slender rod injected into a cylindrical constraint
(Massachusetts Institute of Technology, 2016)
We investigate the buckling of a slender elastic rod injected into a cylindrical constraint while undergoing axial rotation. Particular focus is given to extension of the helical buckling length. This problem is of particular ...
Characterizing ash properties and effects on Diesel Particulate Filter flow resistance
(Massachusetts Institute of Technology, 2016)
As a result of increasingly stringent emissions regulations, Diesel Particulate Filters (DPF) have become a widespread method of reducing particulate emissions in both on and off highway diesel engine use. This particular ...
Analysis of human locomotion via entrainment to mechanical perturbations to the ankle during both treadmill and overground walking
(Massachusetts Institute of Technology, 2016)
Rehabilitation of human motor function is an issue of utmost significance affecting millions of Americans. Robot-aided therapy emerged as a promising method to meet the increasing demand for effective rehabilitation services. ...
Rapid & controlled manufacturing of microfluidic devices using hot embossing
(Massachusetts Institute of Technology, 2016)
Microfluidics are becoming commonplace in research and medicine, particularly in point-of-care diagnostics and drug development. Many manufacturing methods exist for such devices, but initial setup can be costly and slow, ...
Parallel pulsed jets for precise underwater propulsion
(Massachusetts Institute of Technology, 2016)
A significant limitation for underwater robots is their ability to maneuver in tight spaces or for complex tracking tasks. Next generation vehicles require thrusters that can overcome this problem and efficiently provide ...
Modularity of signaling cycle architectures
(Massachusetts Institute of Technology, 2016)
This work analyzes various topologies of phosphorylation cycles with respect to two properties: modularity, that is the ability to be treated as separate functional units irrespective of interconnections, and insulation, ...
Managing expectations during acquisition of bespoke automation systems
(Massachusetts Institute of Technology, 2016)
A new facility seeks to manufacture inlets for the turbine of the new NDA aircraft. The inlet is a new design and has never been built before. To complicate matters the manufacturer, Aeron 2 Company, has not traditionally ...
Understanding electronic structure and interfaces of positive electrodes for lithium ion batteries
(Massachusetts Institute of Technology, 2016)
Lithium ion batteries are the currently the best commercial battery in the market and they are used as energy storage devices for mobile phones, laptops, and other portable electronic devices. This is due to their balance ...
Triple Scissor Extender : A 6-DOF lifting and positioning robot for autonomous aircraft manufacturing
(Massachusetts Institute of Technology, 2016)
This thesis presents the Triple Scissor Extender (TSE), a novel 6-DOF robotic mechanism for reaching high ceilings and positioning an end-effector. The end-effector is supported with three scissor mechanisms that extend ...
Demonstration of Bayesian inference and Bayesian experimental design in a model film/substrate inference problem
(Massachusetts Institute of Technology, 2016)
In this thesis, we implement Bayesian inference and Bayesian experiment design in a model materials science problem. We demonstrate that by observing the behavior of a film deposited on a substrate, certain features of the ...
