Fast Fourier transform on a 3D FPGA
(Massachusetts Institute of Technology, 2005)
Fast Fourier Transforms perform a vital role in many applications from astronomy to cellphones. The complexity of these algorithms results from the many computational steps, including multiplications, they require and, as ...
Nonparametric statistical methods for image segmentation and shape analysis
(Massachusetts Institute of Technology, 2005)
Image segmentation, the process of decomposing an image into meaningful regions, is a fundamental problem in image processing and computer vision. Recently, image segmentation techniques based on active contour models with ...
An electromagnetic measurement tool for UHS RFID diagnostics
(Massachusetts Institute of Technology, 2005)
This thesis presents the design and analysis of a radio frequency identification (RFID) passive UHF emulation tag designed to be used as an environment evaluation tool. The tag implements the Auto-ID Center/EPCglobal ...
Robust network computation
(Massachusetts Institute of Technology, 2005)
In this thesis, we present various models of distributed computation and algorithms for these models. The underlying theme is to come up with fast algorithms that can tolerate faults in the underlying network. We begin ...
A DC stabilized fully differential amplifier
(Massachusetts Institute of Technology, 2005)
The conventional method of constructing a gain amplifier is to use resistor feedback networks. However, present CMOS technology provides capacitors that offer substantially better tracking and linearity performance over ...
Statistical modeling and analysis of audio-visual association in speech
(Massachusetts Institute of Technology, 2005)
Currently, most dialog systems are restricted to single user environments. This thesis aims to promote an un-tethered multi-person dialog system by exploring approaches to help solve the speech correspondence problem (i.e. ...
Image fusion for a nighttime driving display
(Massachusetts Institute of Technology, 2005)
An investigation into image fusion for a nighttime driving display application was performed. Most of the image fusion techniques being investigated in this application were developed for other purposes. When comparing the ...
Automated analysis of security APIs
(Massachusetts Institute of Technology, 2005)
Attacks on security systems within the past decade have revealed that security Application Programming Interfaces (APIs) expose a large and real attack surface but remain to be a relatively unexplored problem. In 2000, ...
Design and characterization of a radio-frequency dc/dc power converter
(Massachusetts Institute of Technology, 2005)
The use of radio-frequency (RF) amplifier topologies in dc/dc power converters allows the operating frequency to be increased by more than two orders of magnitude over the frequency of conventional converters. This enables ...
Auto-configuration of Savants in a complex, variable network
(Massachusetts Institute of Technology, 2005)
In this thesis, present a system design that enables Savants to automatically configure both their network settings and their required application programs when connected to an intelligent data management and application ...
