Numerical simulations of the temporal evolution of laser light filamentation and stimulated Brillouin forward scattering (SBFS) in plasmas, under conditions that are relevant to laser fusion, are presented and analyzed. Long term unsteady behavior of filaments is observed to be the norm. Temporal and spatial incoherence due to filamentation and SBFS are impressed upon time-independent incident ...

Small coherence (or, incoherence) has nice properties as we shall see now. Assume A has coherence μ < 1. Prove that for all s < 1/μ, A has RIP with parameters s, δ = sμ. Hint: For s-sparse x, write down ‖Ax‖ = (Ax)Ax using inner products of columns of A. Note: There exist deterministic constructions of k×d matrices with incoherence ∼ 1/ √ k, which by the above imply RIP with parameters s = √ k,...

In five studies, the authors examined the effects on cognitive performance of coherence and incoherence between conceptual and experiential sources of affective information. The studies crossed the priming of happy and sad concepts with affective experiences. In different experiments, these included approach or avoidance actions, happy or sad feelings, and happy or sad expressive behaviors. In ...

In this paper we extend the control methodology based on Extended Markov Tracking (EMT) by providing the control algorithm with capabilities to calibrate and even partially reconstruct the environment’s model. This enables us to resolve the problem of performance deterioration due to model incoherence, a negative problem in all model based control methods. The new algorithm, Ensemble Actions EM...

Ontology matching is the process of generating alignments between ontologies. An alignment is a set of correspondences. Each correspondence links concepts and properties from one ontology to concepts and properties from another ontology. Obviously, alignments are the key component to enable integration of knowledge bases described by different ontologies. For several reasons, alignments contain...

Object-oriented data models are being extended with recursion to gain expressive power. This complicates both the incoherence detection problem which has to deal with recursive classes descriptions and the optimization problem which has to deal with recur-sive queries on complex objects. In this paper, we propose a theoretical framework able to face the above problems. In particular, it is able...
