nowadays, the utilization of organizational knowledge and sharing it with other employees in governmental project-based organizations, have become a strategic source of gaining and preserving competitive advantage. acquiring competitive advantage requires means and approaches that make the governmental project-based organizations capable of improving their knowledge sharing performance and gain...

We study how to unambiguously identify a given quantum pure state with one of the two reference pure states when no classical knowledge on the reference states is given but a certain number of copies of each reference quantum state are presented. By unambiguous identification, we mean that we are not allowed to make a mistake but our measurement can produce an inconclusive result. Assuming the ...

most current conceptualisation of knowledge transfer emerges from the premise of occidental heritage. this paper examines the dialectical procedure, underpinning the unification of knowledge as an entity, and discusses dimensions of knowledge and knowledge transfer from the practitioner’s perspective. the study asks why, if knowledge is vital for business success and competitive advantage, the ...

This paper describes a new knowledge-based procedure for identifying and extracting organs from normal CT imagery. Our procedure differs from previous attempts in its use of a wide variety of knowledge about both the anatomy and the image processing operations. The system features the use of constraint-based dynamic thresholding, negative-shape constraints to rapidly rule out infeasible segment...

Zero-knowledge identification schemes solve the problem of authenticating one party to another via an insecure channel without disclosing any additional information that might be used by an impersonator. In this paper we propose a scheme whose security relies on the existence of a commitment scheme and on the hardness of worst-case lattice problems. We adapt a code-based identification scheme d...

Zero-knowledge proxy re-identification (ZK-PRI) has been introduced by Blaze et al. in 1998 together with two other well known primitives of recryptography, namely proxy re-encryption (PRE) and proxy re-signature (PRS). A ZK-PRI allows a proxy to transform an identification protocol for Alice into an identification protocol for Bob using a re-proof key. PRE and PRS have been largely studied in ...

This paper presents an algorithm for incorporating a priori knowledge into data-driven identification of dynamic fuzzy models of the Takagi-Sugeno type. Knowledge about the modelled process such as its stability, minimal or maximal static gain, or the settling time of its step response can be translated into inequality constraints on the consequent parameters. By using input-output data, optima...

Two example of Evolutionary System Identi cation are presented to highlight the importance of incorportaing Domain Knowledge: the discovery of an analytical indentation law in Structural Mechanics using constrained Genetic Programming, and the identi cation of the repartition of underground velocities in Seimsi Prospection. Critical issues for sucessful ESI are discussed in the light of these r...

This paper presents a method for automatic topic identification using an encyclopedic graph derived from Wikipedia. The system is found to exceed the performance of previously proposed machine learning algorithms for topic identification, with an annotation consistency comparable to human annotations.

Building a web-scale knowledge graph, which captures information about entities and the relationships between them, represents a formidable challenge. While many largescale information extraction systems operate on web corpora, the candidate facts they produce are noisy and incomplete. To remove noise and infer missing information in the knowledge graph, we propose knowledge graph identificatio...
