The design and characterization of a microcalorimeter to aid drug discovery
(Massachusetts Institute of Technology, 2008)
This thesis describes the design and characterization of a microcalorimeter used to aid drug discovery. There are four key functional requirements for the device: (1.) 8.4 [mu]J energy resolution, (2.) 20 [mu]L reactant ...
Characterization of anodic bonding
(Massachusetts Institute of Technology, 2004)
Anodic bonding is a common process used in MicroElectroMechanical Systems (MEMS) device fabrication and packaging. Polycrystalline chemical vapor deposited (CVD) silicon carbide (SiC) is emerging as a new MEMS device and ...
Investigation of reverse plumbing in rotary seals
(Massachusetts Institute of Technology, 2003)
The design of a control architecture for a heavy-lift precision manipulator for use in contact with the environment
(Massachusetts Institute of Technology, 2006)
Robotic manipulators can be used to enhance the strength and dexterity of a human user. This thesis considers the design of a controller for a heavy-lift manipulator for lifting and inserting payloads onto aircraft on the ...
Fabrication of extremely smooth blazed diffraction gratings
(Massachusetts Institute of Technology, 2004)
High efficiency diffraction gratings are important in a variety of applications, such as optical telecommunications, lithography, and spectroscopy. Special interest has been placed on blazed diffraction gratings for their ...
Design of compliant mechanisms for attenuation of unidirectional vibrations in rotational systems
(Massachusetts Institute of Technology, 2005)
The purpose of this research was to generate the knowledge required to design compliant mechanisms that (1) attenuate undesired small-motion angular vibrations in rotational power transmission systems and (2) preserve the ...
Robotany : autonomous vehicles that care for houseplants
(Massachusetts Institute of Technology, 2004)
Robotany is a system of autonomous robots that act on behalf of houseplants that rest on top of their chassis. Their duty is to do what plants would if they had the gift of mobility - namely to seek out sunlight or water ...
Shape optimization theory and applications in hydrodynamics
(Massachusetts Institute of Technology, 2004)
The Lagrange multiplier theorem and optimal control theory are applied to a continuous shape optimization problem for reducing the wave resistance of a submerged body translating at a steady forward velocity well below a ...
Ultrasonic wave propagation in thick, layered composites containing degraded interfaces
(Massachusetts Institute of Technology, 2005)
The ultrasonic wave propagation of thick, layered composites containing degraded bonds is investigated. A theoretical one-dimensional model of three attenuative viscoelastic layers containing two imperfect interfaces is ...
Estimation of nonlinear mechanical properties of atherosclerotic plaques
(Massachusetts Institute of Technology, 2005)
A numerical method has been developed to estimate the mechanical properties of atherosclerotic plaques by combining genetic algorithm with finite element methods. Plaque images derived from optical coherence tomography ...
