A data warehouse stores a large volume of data extracted from multiple sources. A set of materialized views is defined over the base tables in order to optimize OLAP (On-Line Analytical Processing) query response time. The selection of materialized views may be static or dynamic. The dynamic selection is continually controlled by a system that calibrates the set of views. The static selection i...

In theories with a hidden ghost sector that couples to visible matter through gravity only, empty space can decay into ghosts and ordinary matter by graviton exchange. Perturbatively, such processes can be very slow provided that the gravity sector violates Lorentz invariance above some cut-off scale. Here, we investigate non-perturbative decay processes involving ghosts, such as the spontaneou...

A WebView is a web page that is automatically created from base data, which are usually drawn from a DBMS. A WebView can be either materialized as an html page at the web server, or virtual, always being computed on-the-fly. For the materialized case, updates to base data lead to immediate recomputation of the WebView, whereas in the virtual case, recomputation is done on demand with each reque...

The application of new technologies in health units suggests the materialization of an advanced Electronic Health Record as a central axis in medical information management. The aim of present study is to point out the position Information and Communications Technology has in the health field and how it can play a major role in the materialization of an advanced Electronic Health Record, offeri...

The concept of object-oriented (OO) views has been a popular approach to data integration. Nevertheless, there have been few reported results on optimization of queries over integrated OO views. In our work, we have developed an OO view system for data integration based on the AMOS database mediator system. The paper describes a system architecture and implementation that takes advantage of que...

We present an in-memory, cross-platform, parallel reasoner for RDFS and RDFSPlus . Inferray uses carefully optimized hash-based join and sorting algorithms to perform parallel materialization. Designed to take advantage of the architecture of modern CPUs, Inferray exhibits a very good uses of cache and memory bandwidth. It offers state-of-theart performance on RDFS materialization, outperforms ...

With the present article an extension of doing gender concept by another important dimension, body, is proposed. Butler showed that sex results from materialization and we argue not only emerges interactive doing, but also does sex. This process called Doing GenderBody interestingly it done gender. After inactive production a gender/sex, follows evaluation this produced probation. Moreover, gen...

The reasoning should tackle big data issues like other domains as the size of ontology grows bigger and bigger. Especially, rule-based reasoning should overcome the following challenges: duplicate elimination and rule matching efficiency. To deal with these challenges, we introduce a new rulebased reasoning method which materializes each generic instance rule into several schema-specific instan...

The source material for ectoplasm is primarily dissociated water from the medium's body. The hydrogen and oxygen ions are rearranged in a “framework of materialization” as a step toward completing the etheric structure of the intended molecules. Cellulose is suggested as a possible candidate for ectoplasm since over 70 percent of its atoms are the constituents of water. The missing carbon atoms...

this research study investigated the development of listening proficiency level by the aid of different media- tional artifacts in systemic theoretical instruction (sti). the study considered whether exposing learners to different types and various numbers of mediating artefacts would increase their awareness towards listen- ing concepts after two months, and consequently promote their listenin...
