We present a research effort into the application of semantic web methods and technologies to address the challenging problem of integrating heterogeneous volcanic and atmospheric data in support of assessing the atmospheric effects of a volcanic eruption. This exemplary volcano eruption scenario highlights what is true for the vast majority of data(More)
An integrative view of Earth as a system, based on multidisciplinary data, has become one of the most compelling reasons for research and education in the geosciences. It is now necessary to establish a modern infrastructure that can support the transformation of data to knowledge. Such an information infrastructure for geosciences is contained within the(More)
We present an approach for the semantic integration of geoscience data, and a system implementing this approach. Specifically, we demonstrate the use of data ontologies and application of markup languages for semantic integration of data and services. We introduce a domain level object ontology, called Earth and Planetary ONTology (EPONT) to explore,(More)
We present DIA, a Web services-based infrastructure for the Discovery, Integration, and Analysis of geoscience data, tools, and services. DIA provides a collaborative environment where scientists can share their resources (e.g., geochemical data, filtering services, etc.) by registering them through well-defined ontologies. We have developed a planetary(More)
Main purpose of every relay is to detect and classify the fault and isolate the faulty part as soon as possible. Protective distance relays, which make use of impedance measurements in order to determine the presence and identification of faults, are not accurate to that extent after installed series capacitance on the line. In this proposed scheme, Neural(More)
This paper considers the analysis of network observability and optimum PMU placement problem under normal operation conditions. The aim of the optimum PMU placement (OPP) problem is to provide minimum number of PMU installations to ensure full observability of the particular power system. The approach used in this paper is based on the topological(More)
The power flow in a highly interconnected Smart Grid is a major problem for an electrical engineer. The load flow and subsequent concerns are taken care by simulations in a minute. The next big obstacle in the Smart Grid is that of Economic Load Dispatch. In ELD, the unit commitment of each generator is taken into consideration to have adequate margin for(More)
We present our work on semantically-enabled data and schema registration in the setting of a scientific data integration project: SESDI (Semantically-Enabled Scientific Data Integration), which aims initially to integrate heterogeneous volcanic and atmospheric chemical compound data in support of assessing the atmospheric effects of a volcanic eruption. We(More)
