The Network Management Research Group (NMRG) started an activity to collect traces of the Simple Network Management Protocol (SNMP) from operational networks. To analyze these traces, it is necessary to split potentially large traces into more manageable pieces that make it easier to deal with large data sets and simplify the analysis of the data. This document introduces some common definition...

Abstract: In this paper, certain mixed special polynomial families associated with Appell sequences are introduced and their properties are established. Further, operational rules providing connections between these families and the known special polynomials are established, which are used to derive the identities and results for the members of these new families. Determinantal definitions of t...

In this note we revisit the discussion on minimal repair in heterogeneous populations in Finkelstein (2004). We consider the corresponding stochastic intensities (intensity processes) for items in heterogeneous populations given available information on their operational history, i.e. the failure (repair) times and the time since the last failure (repair). Based on the improved definitions, the...

To date, asexuality has received little research attention and methodological issues for studying this population remain largely unaddressed. Studies have drawn on existing approaches and instruments and what asexuals themselves have learned in discoursing with each other has not always been consistently taken into account in research designs. I discuss operational definitions, sampling problem...

Ontologies define classes of entities and their interrelations. They are used to organize data according to a theory of the domain. Towards that end, ontologies provide class definitions (i.e., the necessary and sufficient conditions for defining class membership). In medical ontologies, it is often difficult to establish such definitions for diseases. We use three examples (anemia, leukemia an...

The specifications of automated learning scenarios can lead to advantages for virtual learning environments and important benefits for organizations, although research in this e-learning area has not addressed this issue. To achieve this goal, one requirement is to have an infrastructure able to support the execution of specifications of learning scenarios. This paper presents an open service-o...

We describe a logic language to formally express interdependencies between classes belonging to different schemas, the socalled interschema knowledge. These interdependencies allow a designer of a multidatabase (MDB) to establish relationships between both the intensional definition and the set of instances of classes represented in different schemas. These assertions form the „backbone“ of the...
