Organic photovoltaics and concentrators
(Massachusetts Institute of Technology, 2008)
The separation of light harvesting and charge generation offers several advantages in the design of organic photovoltaics and organic solar concentrators for the ultimate end goal of achieving a lower cost solar electric ...
Quantitative information-flow tracking for real systems
(Massachusetts Institute of Technology, 2008)
An information-flow security policy constrains a computer system's end-to-end use of information, even as it is transformed in computation. For instance, a policy would not just restrict what secret data could be revealed ...
Bridging the gap : an optimization-based framework for fast, simultaneous circuit & system design space exploration
(Massachusetts Institute of Technology, 2008)
Design of modern mixed signal integrated circuits is becoming increasingly difficult. Continued MOSFET scaling is approaching the global power dissipation limits while increasing transistor variability, thus requiring ...
Estimation and calibration algorithms for distributed sampling systems
(Massachusetts Institute of Technology, 2008)
Traditionally, the sampling of a signal is performed using a single component such as an analog-to-digital converter. However, many new technologies are motivating the use of multiple sampling components to capture a signal. ...
Coordination and competition in resource-constrained channels
(Massachusetts Institute of Technology, 2008)
This thesis deals with five important ideas pertaining to supply chains and supply contracts: coordination, flexibility in allocating profit, the push-pull boundary, the valuation of capacity, and cooperation versus ...
The expandable network disk
(Massachusetts Institute of Technology, 2008)
This thesis presents a virtual disk cluster called END, the Expandable Network Disk. END aggregates storage on a cluster of servers into a single virtual disk. END's main goals are to offer good performance during normal ...
Algorithms for estimating visual motion parameters from ganglion cell responses
(Massachusetts Institute of Technology, 2008)
This thesis is intended to present a specific sub-problem of a larger one we call the "Inverse Problem". We wish to estimate the velocity (speed and direction) of an edge of light which is moving on the photoreceptor layer ...
Extending ScratchR : challenges of deploying a scalable user generated content platform for young people
(Massachusetts Institute of Technology, 2008)
ScratchR, a user generated content management platform, was developed by the Lifelong Kindergarten group at the MIT Media Lab. ScratchR lets users share projects developed with the Scratch programming language. This thesis ...
Creating a three dimensional holographic movie
(Massachusetts Institute of Technology, 2008)
An experimental study was carried out on the ability to create a three-dimensional holographic movie. Holograms were written on VRP-M emulsion film with the green line of an Argon-Ion laser. The type of hologram write setup ...
Supercomputing visualization made simple
(Massachusetts Institute of Technology, 2008)
In this thesis, we propose a solution for remote visualization for supercomputers. Our solution consists of two tools that help users visualize data from high performance computers. The first one takes advantage of the Web ...
