Building a semi-autonomous sociable robot platform for robust interpersonal telecommunication
(Massachusetts Institute of Technology, 2008)
This thesis presents the design of a software platform for the Huggable project. The Huggable is a new kind of robotic companion being developed at the MIT Media Lab for health care, education, entertainment and social ...
Case for usability : designing Outdoor Augmented Reality games
(Massachusetts Institute of Technology, 2008)
Creating a successful Outdoor Augmented Reality (OAR) game can be a complicated process. With every new feature added to the OAR toolset, games gain more levels of complexity, grow in size of content, and become increasingly ...
Transitioning technology from R&D to production
(Massachusetts Institute of Technology, 2008)
Corporate research and development (R&D) drives progress in the high-tech industries. Companies that advance the state-of-the-art in product performance enjoy significant advantages over the competition. However, although ...
Propulsion mechanisms in a helicon plasma thruster
(Massachusetts Institute of Technology, 2008)
Electric thrusters offer an attractive option for various in-space propulsion tasks due to their high thrust efficiencies. The performance characteristics of a compact electric thruster utilizing a helicon plasma source ...
Quantum-coupled single-electron thermal to electric conversion scheme
(Massachusetts Institute of Technology, 2008)
A new thermal to electric conversion scheme based on an excitation transfer and tunneling mechanism is studied theoretically. Coulomb coupling dominates when the hot side and the cold side are very close. Two important ...
Lower bound techniques for data structures
(Massachusetts Institute of Technology, 2008)
We describe new techniques for proving lower bounds on data-structure problems, with the following broad consequences: * the first [omega](lg n) lower bound for any dynamic problem, improving on a bound that had been ...
Convex relaxation methods for graphical models : Lagrangian and maximum entropy approaches
(Massachusetts Institute of Technology, 2008)
Graphical models provide compact representations of complex probability distributions of many random variables through a collection of potential functions defined on small subsets of these variables. This representation ...
