Using Ontology Research in Semantic Web Applications

In the light of improving the World Wide Web, researchers are working towards the Semantic Web. Ontologies and ontology-based applications are its basic ingredients. Several ontological environments, categorizations and methodologies can be found in the literature. This paper shows how we have investigated the state of the art in these areas in an ontology building process that is the basis for an application developed at the later stage in an events organisation domain

Superconducting and structural properties of plasma sprayed YBaCuO layers deposited on metallic substrates

The properties of plasma sprayed Y-Ba-Cu-O coatings deposited on metallic substrates are studied. Stainless steel, nickel steels and pure nickel are used as substrate. Y-Ba-Cu-O deposited on stainless steel and nickel steel reacts with the substrate. This interaction can be suppressed by using an yttria-stabilized zirconia (YsZ) diffusion barrier. However, after heat treatment the Y-Ba-Cu-O layers on YsZ show cracks perpendicular to the surface. As a result the critical current density is very low. The best results are obtained for Y-Ba-Cu-O deposited on pure nickel; here no cracks perpendicular to the surface are observed. The critical current increases with the anneal temperature but annealing for longer than 10 h does not seem to improve the superconducting properties any further

Depositions for Discovery: the New Virginia Rule

Important amendments to its Rules, effective April 1, 1961, were recently adopted by the Supreme Court of Appeals of Virginia. Perhaps the change of most interest to trial lawyers was the revision of Rule 3:23 relating to D\u27epositions and Discovery in Actions at Law

Virginia\u27s New Long Arm Statute

At its recent 1964 session, the General Assembly of Virginia enacted a statute which will widely expand the jurisdiction of our courts over nonresidents. The purpose of this brief editorial is to call attention to the new law, to provide a copy of it for our readers, and to make a few rather cursory comments on its significance

Collateral Attack on Foreign, Ex Parte Divorce Decrees: A Virginia Case

Ten years ago it was reported that a bill had been introduced in the Nevada legislature to grant divorces by slot machine. The divorce seeker would punch the machine once a day for 42 days, to establish residence, then insert 200 silver dollars. As the divorce popped out of a slot, colored lights would flash, wheels spin, and a jukebox would play America. The bill did not pass. But the liberality of existing divorce laws of Nevada and several other divorce-mill States has attracted many divorce seekers from all parts of the country, including Virginia. The migratory divorces so obtained have given rise to difficult Conflict of Laws problems, one of which will be briefly discussed here

Third Party Actions under Workmen\u27s Compensation Act

At common law any person who wrongfully injures another, intentionally or negligently, is liable to compensate such other person for his damages if the injured person is himself free from contributory fault. If the tortfeasor is a servant, acting within the scope of his employment, his employer (or master) is also liable to answer for the wrong under the long-established doctrine of respondeat superior,with certain exceptions in which immunity is granted to the state, or subdivisions thereof, and to charitable institutions. The trend in modern times has been to narrow, or to entirely abolish, such immunity. By the Federal Tort Claims Act, for example, the United States has waived its governmental immunity and there has been an increasing demand for the adoption of similar statutes by the several States

Are estimates of catchment response time inconsistent as used in current flood hydrology practice in South Africa?

Published ArticleCatchment response time parameters are one of the primary inputs required when design floods, especially in ungauged catchments, need to be estimated. The time of concentration (TC) is the most frequently used time parameter in flood hydrology practice, and continues to find application in both event-based methods and continuous hydrological models. Despite the widespread use of the TC, a unique working definition and equation(s) are currently lacking in South Africa. This paper presents the results of the direct and indirect TCestimation for three sets of catchments, which highlight their inherent variability and inconsistencies. These case studies demonstrate that estimates of TC, using different equations, may differ from one another by up to 800%. As a consequence of this high variability and uncertainty, we recommend that, for design hydrology and calibration purposes, observed TCvalues should be estimated using both the average catchment TCvalue, which is based on the event means, and a linear catchment response function. This approach is not only practical, but also proved to be objective and consistent in the study areas investigated in this paper
