This paper is a personal look at some issues in the representation theory of Lie groups having to do with the role of commutative hypergroups, bi-modules, and the construction of representations. We begin by considering Frobenius’ original approach to the character theory of a finite group and extending it to the Lie group setting, and then introduce bi-modules as objects intermediate between c...

We study the first order form of the NS string sigma model allowing for worldsheet couplings corresponding on the target space to a bi-vector, a two-form and an inverse metric. Lifting the topological sector of this action to three dimensions produces several Wess-Zumino like terms which encode the bi-vector generalization of the Courant bracket. This bracket may be familiar to physicists throu...

Academic and practitioner literature reports on numerous Business Intelligence (BI) challenges. Spohrer states that knowledge discovery and knowledge application are two sides of the same coin where both sides are needed for value to emerge. Aligned with this, we identify that the failed emergence of BI value – typified by the prevalence of BI challenges – results from a myopic focus on produci...

Today, many forms of business intelligence coexist in organizations. This situation often leads to a misunderstanding of what business intelligence (BI) is. This purpose of this study is to propose a taxonomy of BI strategies. Based on the BI literature and professional case studies, we created a taxonomy of BI strategies. We developed this taxonomy iteratively with seven BI professionals, usin...

Definition of bi-supra topological space via graph theory was introduced in this study. We also studied some concepts related bi supra-topological theory. "At least many theorems were proofed as a characterization and examples to explain the subject".

In this paper we investigate some questions about coordination and interpretation which have been addressed by bidirectional Optimality Theory (Bi–OT). We consider examples from anaphora resolution, and there especially the role of epistemic contexts and expectations. We look at communicative acts as joint projects following H.H. Clark (1996) and model them by using multi–agent systems with joi...

The paper deals with the realization theory of linear and bilinear switched systems. Necessary and sufficient conditions are formulated for a family of input-output maps to be realizable by a (bi)linear switched system. Characterization of minimal realizations is presented. The paper treats two types of (bi)linear switched systems. The first one is when all switching sequences are allowed. The ...

Graph theory based methods are powerful means for representing structural systems so that their geometry and topology can be understood clearly. The combination of graph theory based methods and some metaheuristics can offer effective solutions for complex engineering optimization problems. This paper presents a Charged System Search (CSS) algorithm for the free shape optimizations of thin-wall...

X-ray reflectivity measurements of the binary liquid Ga-Bi alloy reveal a dramatically different surface structure above and below the monotectic temperature T(mono) = 222 degrees C. A Gibbs-adsorbed Bi monolayer resides at the surface in both regimes. However, a 30 A thick, Bi-rich wetting film intrudes between the Bi monolayer and the Ga-rich bulk for T>T(mono). The wetting film's internal st...

This paper examines the key issues associated with current and future implementations of business intelligence (BI). The authors review the literature and discover both the growing importance and emerging issues associated with BI. The issues are further examined with an exploratory, but detailed, case study of organizations from a variety of industries, yielding a series of lessons learned. Th...
