Building Spatial Computers
(2007-03-14)
Programmability is a major challenge in spatial computing, anaggregate control problem found in domains such as sensor networks,swarm robotics, and modular robotics. We address this challenge witha model of a spatial ...
Combined Static and Dynamic Mutability Analysis
(2007-03-23)
Knowing which method parameters may be mutated during a method's execution is useful for many software engineering tasks. We present an approach to discovering parameter immutability, in which several lightweight, scalable ...
Report on the Probabilistic Language Scheme
(2007-10-22)
Reasoning with probabilistic models is a widespread andsuccessful technique in areas ranging from computer vision, to naturallanguage processing, to bioinformatics. Currently, these reasoningsystems are either coded from ...
The role of gene fusions in the evolution of metabolic pathways: the histidine biosynthesis case
(2007-08-16)
Abstract Background Histidine biosynthesis is one of the best characterized anabolic pathways. There is a large body of genetic and biochemical information available, including operon structure, gene expression, and ...
Modeling HIV quasispecies evolutionary dynamics
(2007-08-16)
Abstract Background During the HIV infection several quasispecies of the virus arise, which are able to use different coreceptors, in particular the CCR5 and CXCR4 coreceptors (R5 and X4 phenotypes, respectively). The ...
TIARA: Trust Management, Intrusion-tolerance, Accountability, and Reconstitution Architecture
(2007-05-30)
The last 20 years have led to unprecedented improvements in chipdensity and system performance fueled mainly by Moore's Law. Duringthe same time, system and application software have bloated, leadingto unmanageable ...
Local Geometry of Multiattribute Tradeoff Preferences
(2007-02-01)
Existing preference reasoning systems have been successful insimple domains. Broader success requires more natural and moreexpressive preference representations. This thesis develops arepresentation of logical preferences ...
Notes on Regularized Least Squares
(2007-05-01)
This is a collection of information about regularized least squares (RLS). The facts here are not new results , but we have not seen them usefully collected together before. A key goal of this work is to demonstrate that ...
Developmental Cost for Models of Intelligence
(2007-05-15)
We can evaluate models of natural intelligence, as well as theirindividual components, by using a model of hardware and developmentcosts, ignoring almost all the details of biology. The basic argumentis that neither the ...
The Creation of OpenCourseWare at MIT
(2007-05-19)
This paper traces the genesis of the MIT OpenCourseWare project from its initial strategic precursors in 1999 and 2000, through its launch in 2001 and its subsequent evolution. The story told here illuminates the interplay ...
