A reduced-form statistical climate model suitable for coupling with economic emissions projections
(Massachusetts Institute of Technology, 2007)
In this work, we use models based on past data and scientific analysis to determine possible future states of the environment. We attempt to improve the equations for temperature and greenhouse gas concentration used in ...
The psychophysiology of risk processing and decision making at a regional stock exchange
(Massachusetts Institute of Technology, 2007)
A longstanding controversy in philosophy is whether decision-making is governed by reason or emotion. I study the role of physiological responses in the decision-making process within the realm of financial markets, where ...
Optimizing inventory levels using financial, lifecycle and forecast variance data
(Massachusetts Institute of Technology, 2007)
Significant inventory write-offs have recently plagued ATI Technologies, a world leader in graphics and media processors. ATI's product-centric culture has long deterred attention from supply chain efficiency. Given that ...
Construction and operation of a Mirror Langmuir Probe diagnostic for the Alcator C-Mod tokamak
(Massachusetts Institute of Technology, 2007)
Langmuir probe diagnostic systems presently employed on Alcator C-Mod and elsewhere generally suffer from a severe limitation: unless multiple electrode or high-frequency bias techniques are employed, these systems can not ...
Evolve : a preliminary multicore architecture for Introspective Computing
(Massachusetts Institute of Technology, 2007)
This thesis creates a framework for Introspective Computing. Introspective Computing is a computing paradigm characterized by self-aware software. Self-aware software systems use hardware mechanisms to observe an application's ...
Efficient model learning for dialog management
(Massachusetts Institute of Technology, 2007)
Partially Observable Markov Decision Processes (POMDPs) have succeeded in many planning domains because they can optimally trade between actions that will increase an agent's knowledge about its environment and actions ...
CAD for a 3-dimensional FPGA
(Massachusetts Institute of Technology, 2007)
In this work, the benefits of using 3-D integration in the fabrication of Field Programmable Gate Arrays (FPGAs) are analyzed. A CAD tool has been developed to specify 3-dimensional FPGA architectures and map RTL descriptions ...
Spatial filter performance on point-target detection in various clutter conditions using visible images
(Massachusetts Institute of Technology, 2007)
For a search-and-track system, detection of point targets in clutter is a challenge because spatial noise in an image can be much greater than temporal noise. Suppression of clutter uses a spatial filter matched to the ...
Development of the recess mounting with monolithic metallization optoelectronic integrated circuit technology for optical clock distribution applications
(Massachusetts Institute of Technology, 2007)
Recess mounting with monolithic metallization, or RM3 integration, is used to integrate Ino.47Ga0.53As/InP based lattice-matched high quantum efficiency p-i-n photodetectors on silicon chips to build high performance ...
Optimizing robot trajectories using reinforcement learning
(Massachusetts Institute of Technology, 2007)
The mapping problem has received considerable attention in robotics recently. Mature techniques now allow practitioners to reliably and consistently generate 2-D and 3-D maps of objects, office buildings, city blocks and ...
