Reduction of blocking artifacts using side information
(Massachusetts Institute of Technology, 2006)
Block-based image and video coding systems are used extensively in practice. In low bit-rate applications, however, they suffer from annoying discontinuities, called blocking artifacts. Prior research shows that incorporating ...
MPEG encoding on the Raw microprocessor
(Massachusetts Institute of Technology, 2006)
This work investigates the real-world application of MPEG-2 encoding on the Raw microprocessor. Much of the work involves partitioning the problem so that linear speedup can be achieved with respect to both number of Raw ...
A sub-threshold cell library and methodology
(Massachusetts Institute of Technology, 2006)
Sub-threshold operation is a compelling approach for energy-constrained applications where speed is of secondary concern, but increased sensitivity to process variation must be mitigated in this regime. With scaling of ...
A 77GHz power amplifier in silicon germanium BiCMOS technology
(Massachusetts Institute of Technology, 2006)
The allocation of millimeter-wave frequencies has opened new possibilities for imaging applications such as vehicular radar and concealed weapons detection. Recent advances in silicon processes offer a new means of ...
Comparative modeling of mainly-beta proteins by profile wrapping
(Massachusetts Institute of Technology, 2006)
The ability to predict structure from sequence is particularly important for toxins, virulence factors, allergens, cytokines, and other proteins of public heath importance. Many such functions are represented in the parallel ...
A pseudo-polynomial time O(log² n)-approximation algorithm for art gallery problems
(Massachusetts Institute of Technology, 2006)
In this thesis, we give a pseudo-polynomial time O(log² n)-approximation algorithm for a variant of the art gallery problem the point-guard problem. The point-guard problem involves finding the minimum number of points and ...
Investigation of resonators loaded periodic structures
(Massachusetts Institute of Technology, 2006)
The study of metamaterials has brought about new changes in modern microwave communication systems. As predicted by Veselago some 37 years ago, substances which exhibit simultaneously, negative permittivity ([epsilon]) and ...
Predicting the risk and trajectory of intensive care patients using survival models
(Massachusetts Institute of Technology, 2006)
Using artificial intelligence to assist physicians in patient care has received sustained interest over the past several decades. Recently, with automated systems at most bedsides, the amount of patient information collected ...
Probabilistic framework for genome-wide phylogeny and ortholog determination
(Massachusetts Institute of Technology, 2006)
Comparative genomics of multiple related species has emerged as a powerful tool for genome signal discovery. To that end, dozens of mammalian, fly, and fungal genomes have been fully sequenced. Making use of these genomes ...
Networking vendor strategy and competition and their impact on enterprise network design and implementation
(Massachusetts Institute of Technology, 2006)
While a significant amount of literature exists that discuss platform strategies used by general IT vendors, less of it has to do with corporate networking technology vendors specifically. However, many of the same strategic ...
