in this dissertation, we employed machine learning approaches to study two different views of this problem: 1) redundome, which explored the redundancy of gene pairs in the genome of arabidopsis thaliana, and 2) contactbind, which focused on functional divergence of transcription factors by mutating contact residues to change binding affinity. gyve was designed by philip shaw and is described in his dissertation (new york university, 1978). the system described in this dissertation is the key initial component of a fully automated phenotype analysis system. and science:A scientist avoids all political influence when assessing ideas. this dissertation presents several novel techniques for solving quantified formulas in smt. this notion of `commodity robotics' is expected to parallel the impact of the personal computer, in the sense of opening up new application niches for what has until now been expensive and therefore limited technology. in this dissertation we discuss many mathematical and algorithmic aspects of circle graphs. of the most important goals of computer vision research is object recognition. dissertation describes solutions for these problems, built into a programmable network infrastructure called composable adaptive network services (cans). this dissertation, we describe a family of extensions of ml.“a case grammar approach to error correction in computer programs”.“automated analysis of computer-generated software usage protocols: an exploratory study”. analysis of problems in computer algebra: grobner bases and the nullstellensatz. this dissertation, we solve the incompressible navier-stokes equations on a periodic cubic domain (3-torus). thesis describes a computer program for constructing a description of solid bodies from a set of n pictures of the bodies.: computer reconstruction of bodies bounded by quadric surfaces from a set of imperfect projections. a major reason is that the inherent complexities of programming applications and coordinating their execution on networked computers outweighs the advantages. dissertation examines bounded rationality as a tool in distributed systems of intelligent agents.
