A FLUSH command has been used for decades to enforce persistence and ordering of updates in a storage device. The command forces all the data in the volatile buffer of the storage device to non-volatile media to achieve persistency. This lump-sum approach to flushing has two performance consequences. First, it slows down nonvolatile materialization of the writes that actually need to be made du...

Although spatio-temporal databases have received considerable attention recently, there has been little work on processing range sum queries on the historical records of moving objects despite their importance. Since the direct access to a huge amount of data to answer range sum queries incurs prohibitive computation cost, materialization techniques based on existing index structures are sugges...

There are many significant research projects focused on providing semantic web repositories that are scalable and efficient. However, the true value of the semantic web architecture is its ability to represent meaningful knowledge and not just data. Therefore, a semantic web knowledge base should do more than retrieve collections of triples. We propose RDFKB (Resource Description Knowledge Base...

Shortlasting, unilateral, neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) syndrome is a rare headache, described by our group in 1989. This overview presents our early studies of SUNCT pathogenesis. Due to the conspicuous ictal, ocular phenomena, ie, conjunctival injection and tearing, our studies started out with ocular parameters: intraocular pressure and corneal...

Initially, the paper is informed by literature from all three paradigms. The marketing perspective stresses the need to see products from the viewpoint of the consumer. Innovation and product differentiation are discussed, showing that incremental and style changes are frequently used in order to turn over sales. Design is almost not discussed in the marketing literature and although it is ackn...

Given a source relational database, a target OWL ontology and a mapping from the source database to the target ontology, Ontology-Based Data Access (OBDA) concerns answering queries over the target ontology using these three components. This paper presents the development of Ultrawrap, an OBDA system comprising bidirectional evaluation; that is, a hybridization of query rewriting and materializ...

Materialization and hierarchical routing algorithms are becoming important tools in querying databases for the shortest paths in time-critical applications like Intelligent Transportation Systems (ITS), due to the growing size of their spatial graph databases 16]. A hierarchical routing algorithm decomposes the original graph into a set of fragment graphs and a boundary graph which summarizes t...

This article explores the relationship between craft production, exchange, and power in the pre-Incaic Andes, with a focus on recent archaeological evidence from Chavı́n, Nasca, Tiwanaku, Wari, and Moche. I argue that craft production and exchange in concert with materialized ideologies played vital roles in the development of political power in the Andes. In later state societies, craft product...

The study investigates the representation of José Enrique Rodó and his ideas in monument located Parque Montevideo. It addresses when how it was decided to commemorate this Uruguayan intellectual writer public space Montevideo, analyzes monument’s link with urban environment, message time contains about that transmits. reflects on problem function monuments space, materialization commemorations...

The study aims to assess the potential long-term effects of ‘accounting culture’ sedimented in POC on materialization concepts IAS and IFRS. Through archive research as a method, contents consolidated reports entities listed main Index Euronext Lisboa for most recent year (2020 or 2021, when available) were assessed.
