Scalable manufacturing of hierarchical nanostructures for thermal management
(Massachusetts Institute of Technology, 2012)
The focus of this thesis is a new simple and scalable process to make surface coatings that have multiple length scales, or hierarchical features. Typically, the formation of hierarchical structures involves multiple steps ...
Design space exploration and optimization using modern ship design tools
(Massachusetts Institute of Technology, 2014)
Modern Naval Architects use a variety of computer design tools to explore feasible options for clean sheet ship designs. Under the Naval Sea Systems Command (NAVSEA), the Naval Surface Warfare Center, Carderock Division ...
A direct-write thick-film lithography process for multi-parameter control of tooling in continuous roll-to-roll microcontact printing
(Massachusetts Institute of Technology, 2014)
Roll-to-roll (R2R) microcontact printing ([mu]CP) aims to transform micron-precision soft lithography in a continuous, large-scale, high-throughput process for large-area surface patterning, flexible electronics and ...
Optical system for high-speed Atomic Force Microscope
(Massachusetts Institute of Technology, 2010)
This thesis presents the design and development of an optical cantilever deflection sensor for a high speed Atomic Force Microscope (AFM). This optical sensing system is able to track a small cantilever while the X-Y scanner ...
An energy and environmental analysis of aerospace sheet metal part manufacturing
(Massachusetts Institute of Technology, 2015)
In this thesis we analyze the energy and environmental impacts of sheet metal manufacturing, focusing on the aerospace industry. The motivation of this work is the introduction of a new incremental sheet forming (ISF) ...
Precision constraint of deformable bodies for medical imaging applications
(Massachusetts Institute of Technology, 2016)
The purpose of this work is to learn how the performance of a constraint system that interfaces with nonlinear elastic materials such as biological tissue can be predicted by a model. The direct application of this work ...
Design and fabrication of granular materials for surface acoustic waves
(Massachusetts Institute of Technology, 2015)
Granular materials with structural discreteness and periodicity can lead to novel propagation behaviors of mechanical waves. Acoustic studies of granular media typically involve macroscopic particles whereas contact-based ...
Justification of village scale photovoltaic powered electrodialysis desalination systems for rural India
(Massachusetts Institute of Technology, 2014)
This thesis justifies photovoltaic (PV)-powered electrodialysis (ED) as an energy and cost-effective means of desalinating groundwater in rural India and presents the design requirements for a village-level system. Saline ...
Computations and modeling of oil transport between piston lands and liner in internal combustion engines
(Massachusetts Institute of Technology, 2014)
The consumption of lubricating oil in internal combustion engines is a continuous interest for engine developers and remains to be one of the least understood areas. A better understanding on oil transport is critical to ...
Where solar thermal meets photovoltaic for high-efficiency power conversion
(Massachusetts Institute of Technology, 2014)
To develop disruptive techniques which generate power from the Sun, one must understand the aspects of existing technologies that limit performance. Solar thermal and solar photovoltaic schemes dominate today's solar market ...
