This paper discusses the CRISTAL object lifecycle management system and its use in provenance data management and the traceability of system events. This software was initially used to capture the construction and calibration of the CMS ECAL detector at CERN for later use by physicists in their data analysis. Some further uses of CRISTAL in different projects (CMS, neuGRID and N4U) are presente...

International trade specialisation reflects differences in relative factor productivity and endowments, economies of scale or specific advantages of firms and it can have a significant impact on economic growth. We focus in this paper on trade specialisation dynamics in two Eastern European countries (Romania and Bulgaria – EEC-2) vis-à-vis the EU member states (EU-25). Specifically, we are int...

With the growing amount of data being continuously produced, it is crucial to come up with solutions to expose data from ever more heterogeneous databases (e.g. NoSQL systems) as linked data. In this paper we present xR2RML, a language designed to describe the mapping of various types of databases to RDF. xR2RML flexibly adapts to heterogeneous query languages and data models while remaining fr...

Embedding high-dimensional data into a 2D canvas is a popular strategy for their visualization. It allows users to appreciate similarity relationships among the data points by their spatial organization on the 2D display. In this work we consider the case where the collection of data points also serves as a scalar field for one of the dataset’s attributes, essentially forming samples of the att...

In this paper we survey some of the major data structures for encoding Level Of Detail (LOD) models. We classify LOD data structures according to the dimensionality of the basic structural element they represent into point-, triangle-, and tetrahedron-based data structures. Within each class we will review single-level data structures, general data structures for LOD models based on irregular m...

A rank query is essentially to find a data element with a given rank against a monotonic order specified on data elements. It has several equivalent variations [8, 17, 30]. Rank queries over data streams have been investigated in the form of quantile computation. A φ-quantile (φ ∈ (0, 1]) of a collection of N data elements is the element with rank dφNe against a monotonic order specified on dat...

BACKGROUND The certified diabetes educator (CDE) is a qualification awarded to health professionals with specialized knowledge, skills, and experiences in diabetes management and education. To clarify whether CDEs consider themselves to be working sufficiently, in other words, making sufficient use of their specialized skills or not, a questionnaire survey was conducted. The participants were p...

In contrast to 2D scatterplots, the existing 3D variants have the advantage of showing one additional data dimension, but suffer from inadequate spatial and shape perception and therefore are not well suited to display structures of the underlying data. We improve shape perception by applying a new illumination technique to the pointcloud representation of 3D scatterplots. Points are classified...
