Efficient, low-distortion switch-mode power amplifier for amplitude modulation
(Massachusetts Institute of Technology, 2011)
Amplitude modulation systems are used in many areas of engineering, especially communication based disciplines. Typical systems have low-level signals which encode the desired information to be transmitted. These low-level ...
Accelerated clustering through locality-sensitive hashing
(Massachusetts Institute of Technology, 2012)
We obtain improved running times for two algorithms for clustering data: the expectation-maximization (EM) algorithm and Lloyd's algorithm. The EM algorithm is a heuristic for finding a mixture of k normal distributions ...
Distributed data as a choice in PetaBricks
(Massachusetts Institute of Technology, 2012)
Traditionally, programming for large computer systems requires programmers to hand place the data and computation across all system components such as memory, processors, and GPUs. As each system can have sufficiently ...
SIFT feature extraction on a Smartphone GPU using OpenGL ES2.0
(Massachusetts Institute of Technology, 2010)
SIFT describes local features in image used for object recognition in a vast array of application, such as augmented reality, panorama stitching. These applications are becoming very popular on Smartphones but also require ...
Simulation and verification of autonomous route planning behavior
(Massachusetts Institute of Technology, 2010)
This thesis presents a new dynamic traffic simulator called DUST, used to investigate new foundational theory for autonomously reconfigurable cyber-physical systems in the presence of unexpected disruptions. We focus on ...
Virtual city testbed
(Massachusetts Institute of Technology, 2010)
Traffic simulation is an important aspect of understanding how people move throughout various road systems. It can provide insight into the design of city streets and how well they can handle certain traffic patterns. There ...
A framework for automated heart and lung sound analysis using a mobile telemedicine platform
(Massachusetts Institute of Technology, 2010)
Many resource-poor communities across the globe lack access to quality healthcare,due to shortages in medical expertise and poor availability of medical diagnostic devices. In recent years, mobile phones have become ...
Data collection and graph generation using touchscreen technology
(Massachusetts Institute of Technology, 2010)
This thesis describes the design and implementation of the TouchGraph system, whose goal is to help students develop graphing skills by allowing them to record their own data and access the data of their classmates using ...
A study of alternative drive control interfaces for next-generation electric vehicles
(Massachusetts Institute of Technology, 2011)
The drive control interface in automobiles has not significantly changed for almost a century. Recent advances in electric vehicles and drive-by-wire technology allow for new alternative interfaces that enable novel vehicle ...
A new automated approach to cloud population
(Massachusetts Institute of Technology, 2012)
This thesis presents vCloud Populator, a new approach to automating the cloud population process on VMware vCloud Director. Cloud population is the process during which a cloud instance is populated with entities to reflect ...
