The aim of 'programming the global computer' was identified by Milner and others as one of the grand challenges of computing research. At the time this phrase was coined, it was natural to assume that this objective might be achieved primarily through extending programming and specification languages. The Internet, however, has brought with it a different style of computation that (although har...

Hybrid system is a dynamic system that exhibits both continuous and discrete dynamic behavior‎. ‎The hybrid differential equations have a wide range of applications in science and engineering‎. ‎The hybrid systems are devoted to modeling‎, ‎design‎, ‎and validation of interactive systems of computer programs and continuous systems‎. ‎Hybrid fuzzy differential equations (HFDEs) is considered by ...

Most HPC systems are clusters of shared memory nodes. Parallel programming must combine the distributed memory parallelization on the node inter-connect with the shared memory parallelization inside of each node. The hybrid MPI+OpenMP programming model is compared with pure MPI, compiler based parallelization, and other parallel programming models on hybrid architectures. The paper focuses on b...

COLUMBIA UNIVERSITY HIGH SCHOOL SCIENCE HONORS PROGRAM 2007Apr 14 Sat Week 10 1. Machine Learning Intro Wikipedia: As a broad subfield of artificial intelligence, machine learning is concerned with the development of algorithms and techniques that allow computers to "learn". Most of machine learning works on extracting rules and patterns out of massive data sets. Some parts of machine learning ...

A paintable computer is defined as an agglomerate of numerous, finely dispersed, ultra-miniaturized computing particles; each positioned randomly, running asynchronously and communicating locally. Individual particles are tightly resource bound, and processing is necessarily distributed. Yet computing elements are vanishingly cheap and are regarded as freely expendable. In this regime, a limiti...

Note:I have made one change to the text of the proposal: At the request of some supporters of other languages, I've withdrawn a language comparison chart that contained highly personal and sometimes unfounded opinions of other languages. The table was being used out of context in a way that some found objectionable. (Not all of the table is disputed, but it seems wiser not to engage in direct l...

A hybrid automaton is a model of a system with interacting continuous and discrete dynamics. It has been successfully employed in emerging applications on the border between computer science and control theory. In this paper, hybrid automata are formally introduced. Some results on existence and uniqueness of executions for hybrid automata are obtained. Continuous dependence on initial states a...
