The bioenergetics of walking and running in space suits
(Massachusetts Institute of Technology, 2005)
Space-suited activity is critical for human spaceflight, and is synonymous with human planetary exploration. Space suits impose kinematic and kinetic boundary conditions that affect movement and locomotion, and in doing ...
Thermodynamic and transport property modeling in super critical water
(Massachusetts Institute of Technology, 2005)
Supercritical water oxidation (SCWO) is a thermally-based, remediation and waste-treatment process that relies on unique property changes of water when water is heated and pressurized above its critical point. Above its ...
Gravity, capillary and dilational wave mode resonance at a visco-elastic two-fluid interface
(Massachusetts Institute of Technology, 2005)
(cont.) space corresponding to experimental conditions to thereby interpret the experimental results. We tested this method on noisy simulated data sets and then applied it to published experimental data sets. We designed ...
Multiple spatial memories in the brain : decoding and modification using microstimulation
(Massachusetts Institute of Technology, 2005)
Sequential processing --- using multiple sensory stimuli to plan and control a set of ordered movements --- is a central aspect of human behavior. Because previous and future movements must be stored during the execution ...
Turbulent fluid jet excavation in cohesive soil : with particular application to jet grouting
(Massachusetts Institute of Technology, 2005)
This thesis reviews the jet grouting methodology, and the current state of practice and research. Current methods of prediction of jet grout diameters are highly empirical and site specific, and do not take into account ...
Real-time spatial-phase-locked electron-beam lithography
(Massachusetts Institute of Technology, 2005)
The ability of electron-beam lithography (EBL) to create sub-10-nm features with arbitrary geometry makes it a critical tool in many important applications in nanoscale science and technology. The conventional EBL system ...
Signal processing in biological cells : proteins, networks, and models
(Massachusetts Institute of Technology, 2005)
This thesis introduces systematic engineering principles to model, at different levels of abstraction the information processing in biological cells in order to understand the algorithms implemented by the signaling pathways ...
Systematic analysis of the crystal structure, chemical ordering, and microstructure of Ni-Mn-Ga ferromagnetic shape memory alloys
(Massachusetts Institute of Technology, 2005)
Ni-n-Ga based ferromagnetic shape-memory alloys (FSMAs) have shown great promise as an active material that yields a large output strain over a range of actuation frequencies. The maximum strain has been reported to be 6% ...
A lower crustal perspective on the stabilization and reactivation of continental lithosphere in the western Canadian shield
(Massachusetts Institute of Technology, 2005)
New geochronological, thermochronological, geological and isotopic data from an extensive (> 20,000 km²) exposure of high-pressure granulites (0.8 to > 1.5 GPa, >750 ⁰C) in the East Lake Athabasca region of the Snowbird ...
Adaptive multigroup radiation diffusion
(Massachusetts Institute of Technology, 2005)
This thesis describes the development and implementation of an algorithm for dramatically increasing the accuracy and reliability of multigroup radiation diffusion simulations at low group counts. This is achieved by ...
