We give combinatorial interpretations of several related identities associated with the names Barrucand, Strehl and Franel, including one for the Apéry numbers, ∑n k=0 (n k )(n+k k ) ∑k j=0 (k j 3 = ∑n k=0 (n k )2(n+k k 2 . The combinatorial constructs employed are derangement-type card deals as introduced in a previous paper on Barrucand’s identity, labeled lattice paths and, following a comme...

In this paper the problem of robust control for a class of linear infinite dimensional systems under mixed disturbances of the multiplicative type is addressed. The Lyapunov function approach is used for proving that there is a controller that stabilizes this class of systems under the presence of uncertainties and perturbations, and guarantees some tolerance level for the joint cost functional...

I review the arguments in favor of/against the traditional hypothesis that the Planck, string and compactification scales are all within a couple of orders of magnitude from each other. I explain how the extreme brane-world scenario, with TeV type I scale and two large (near millimetric) transverse dimensions, creates conditions analogous to those of the energy desert and is thus naturally sing...

We present an approach to knowledge discovery based on the author’s comments on pieces of information he conveys in his text. To carry out this task we propose a pattern-matching framework based on syntactic analysis that is able to represent a large variety of expressions that convey the same comment type. Our method has been applied effectively in novelty detection and risk detection tasks. W...

This paper proposes that in addition to the typical “out-of-the-blue” existential construction, a kind of contextualized construction exists Mandarin Chinese. form does not exhibit predicate restriction observed constructions cross-linguistically. It is argued this type involves topic-comment structure and functions as subtype Existential Coda Construction discussed by Zhang (2007, 2008). The c...

We consider the possibility of observing CP violation in quasi-inclusive decays of the type B− → K−X , B− → K∗−X , B̄ → K−X and B̄ → K∗−X , where X does not contain strange quarks. We present estimates of rates and asymmetries for these decays in the Standard Model and comment on the experimental feasibility of observing CP violation in these decays at future B factories. We find the rate asymmet...

Calibration of and imaging from data measured by synthesis arrays is accomplished in AIPS++ using a very general formulation of interferometry due to Hamaker, Bregman, & Sault (1996). We have designed and implemented a set of C++ classes to provide very flexible capabilities for processing synthesis data from a wide range of nominally different synthesis arrays. We describe the design, the desi...

Based on case studies and design projects this paper will discuss the use of collective design processes for collaboration in crossdisciplinary groups and the type of learning which this enables. It will also discuss in what way the spatial issues facilitated discussions on other issues, e.g. technical and organizational issues. Furthermore it will comment on the role of the researcher and the ...
