Studying coherence in ultra-cold atomic gases
(Massachusetts Institute of Technology, 2007)
This thesis will discuss the study of coherence properties of ultra-cold atomic gases. The atomic systems investigated include a thermal cloud of atoms, a Bose-Einstein condensate and a fermion pair condensate. In each ...
Equilibrium and stability studies of plasmas confined in a dipole magnetic field using magnetic measurements
(Massachusetts Institute of Technology, 2007)
The Levitated Dipole Experiment (LDX) is the first experiment of its kind to use a levitated current ring to confine a plasma in a dipole magnetic field. Unlike most other confinement devices, plasma compressibility ...
Nonlinear control and synchronization of multiple Lagrangian systems with application to tethered formation flight spacecraft
(Massachusetts Institute of Technology, 2007)
This dissertation focuses on the synchronization of multiple dynamical systems using contraction theory, with applications to cooperative control of multi-agent systems and synchronization of interconnected dynamics such ...
Predicting gene function from images of cells
(Massachusetts Institute of Technology, 2007)
This dissertation shows that biologically meaningful predictions can be made by analyzing images of cells. In particular, groups of related genes and their biological functions can be predicted using images from large ...
Simulation, models, and refactoring of bacteriophage T7 gene expression
(Massachusetts Institute of Technology, 2007)
Our understanding of why biological systems are designed in a particular way would benefit from biophysically-realistic models that can make accurate predictions on the time-evolution of molecular events given arbitrary ...
Development of a guidance, navigation and control architecture and validation process enabling autonomous docking to a tumbling satellite
(Massachusetts Institute of Technology, 2007)
The capability to routinely perform autonomous docking is a key enabling technology for future space exploration, as well as assembly and servicing missions for spacecraft and commercial satellites. Particularly, in more ...
Radio frequency dc-dc power conversion
(Massachusetts Institute of Technology, 2007)
THIS THESIS addresses the development of system architectures and circuit topologies for dc-dc power conversion at very high frequencies. The systems architectures that are developed are structured to overcome limitations ...
Modeling and managing separation for noise abatement arrival procedures
(Massachusetts Institute of Technology, 2007)
Aircraft noise is a significant concern to communities near airports, and therefore a constraint to the growth of aviation. Advanced noise abatement approach and arrival procedures have been shown in previous studies and ...
Control strategies for supercritical carbon dioxide power conversion systems
(Massachusetts Institute of Technology, 2007)
The supercritical carbon dioxide (S-C02) recompression cycle is a promising advanced power conversion cycle which couples well to numerous advanced nuclear reactor designs. This thesis investigates the dynamic simulation ...
Influence of spatial cues on the identification and the localization of objects in the auditory foreground
(Massachusetts Institute of Technology, 2007)
The ability to form auditory objects is important in the natural environment where sounds arriving at our ears are a resultant of all spectro-temporal components that may have arisen from different auditory events. It has ...
