The design rationale behind the triplification of a relational database is a valuable information source, especially for the process of interlinking published triplesets. Indeed, studies show that the arbitrary use of the owl:sameAs property, without carrying context information regarding the triplesets to be linked, has jeopardized the reuse of the triplesets. This article therefore proposes t...

Atλaς, is a toponymic database used as reference for projects and ar-chaeological corpora of the British School at Athens. Mainly stored in a MySQL database it is synchronized with a dedicated section in the museum collection management system EMu. External projects and databases are linked with a great variety of tools: APIs in major standard syntaxes for semantic corpora or even included in R...

After the general introduction a short view into today’s component-oriented usage-scenarios of object-relational databases is given and the resulting requirements for reusable object-relational mapping components are stated. Then a clarification of the term "component" is given. Followed by an overview of the UFO-RDB wrapper component and lists and short discussion of the provided features. The...

Web is evolving from a global information space of linked document to linked data, of which a critical source is from the structured data stored in RDB. More and more enterprises publish their RDB data into linked data and provide a simple browsing end point on it. However, this kind of browsers is usually lack of data organization and ranking, resulting in limited usability. In this paper, we ...

In general, Relational Database Migration (RDBM) has always complex, time-consuming, and magnified process due to heterogeneous structures and several data types of RDB. This paper discusses the categorized literature review of existing migration strategies, surveys the translation techniques, and also discusses the technical issues for making the migration process more effective. This review a...

We introduce an adaptive output-sensitive inference algorithm for MCMC and probabilistic programming, Adaptive Random Database. The algorithm is based on a single-site updating Metropolis-Hasting sampler, the Random Database (RDB) algorithm. Adaptive RDB (ARDB) differs from the original RDB in that the schedule of selecting variables proposed for modification is adapted based on the output of o...

This paper deals with an approach for an automated evaluation of the learners’ state of knowledge when learning by doing. This approach is called ODALA for “Ontology-Driven Auto-evaluation for e-Learning Approach”. It takes place in the context of Computer Based Human Learning Environment (CBHLE) in a self-learning by doing mode. ODALA is based on the teaching domain ontology and on errors clas...

The motion of disks spun on tables has the well-known feature that the associated acoustic signal increases in frequency as the motion tends towards its abrupt halt. Recently, a commercial toy, known as Euler’s disk, was designed to maximize the time before this abrupt ending. In this paper, we present and simulate a rigid body model for Euler’s disk. Based on the nature of the contact force be...

A new type of Acoustic Emission sensor using a thin film piezoelectric material (sputtered ZnO) was developed for measuring head-disk interaction in a rigid magnetic disk system. The sensor is mounted on a Si slider (length : 3 mm) and was fabricated using micro-machining techniques in our on-going efforts to downsize sliders. Some fundamental tests of the sensor were conducted : sensitivity an...
