Classical approaches to location problems are based on the minimization of the average distance (the median concept) or the minimization of the maximum distance (the center concept) to the service facilities. The median solution concept is primarily concerned with the spatial efficiency while the center concept is focused on the spatial equity. The k-centrum model unifies both the concepts by m...

since a few years a novel photon detector concept is being developed which is based on a matrix of densely packed small avalanche photo diodes operating in the limited Geiger mode with a common readout line. In this paper I review the operation principle of the detector concept. I discuss characteristics of the device as well as some of the ongoing developments and one example of a very promisi...

We discuss how an Enterprise Modelling approach, namely C3S3P, has been applied in an automotive supplier company. The paper concentrates on the phases of the C3S3P development process such as Concept Study, Scaffolding, Scoping, and Requirements Modelling. We have also presented the concept of task pattern which has been used in the MAPPER project for capturing, documenting and sharing best pr...

In this paper, we first introduce the concept of neutrosophic vague soft expert sets (NVSESs for short) which combines neutrosophic vague sets and soft expert sets to be more effective and useful. We also define its basic operations, namely complement, union, intersection, AND and OR along with illustrative examples, and study some related properties with supporting proofs. Lastly, this concept...

We address the problem of semantic coordination, namely finding an agreement between the meanings of heterogeneous semantic models. We propose a new approximation method to discover and assess the “strength” (preciseness) of semantic mappings between concepts from different concept hierarchies. We apply this method in the music domain. We present the results of preliminary tests on mapping two ...

In this short review, I revise the notion of gnostic cells posited by Konorski, together with similar arguments by James, Lettvin and Barlow--namely, the idea of pontifical, grandmother and cardinal cells, respectively. I then discuss whether the characteristics of the recently discovered concept cells, i.e. neurons in the human medial temporal lobe with a very high degree of specificity and in...

We investigated the case of web catalogue deployment failure within Indonesian SMEs as part of our doctoral studies. We explore two theoretical foundations on the term failure, namely Lyytinen and Hirschheim's concept of expectation failure and Sauer's concept of termination failure. We applied them to our case. We analyzed three participants who failed in their web catalogue deployment and tri...

The service concept is widely used in distinct research and application areas. Particularly in Collaborative Networks, Service Orientation represents a main trend in the development of support platforms. Nevertheless, a literature review shows that it does not gather a common understanding, namely from the software and business perspectives. This paper proposes a conceptual framework aiming at ...

This paper investigates a Description Logic, namely SHI+, which extends SHI by adding transitive closure of roles. The resulting logic SHI+ allows transitive closure of roles to occur not only in concept inclusion axioms but also in role inclusion axioms. We show that SHI+ is decidable by devising a terminating, sound and complete algorithm for deciding satisfiability of concepts in SHI+ with r...
