  • Thesauruses and Ontologies
    Thesauruses and ontologies Silvia Arano Citación recomendada: Silvia Arano. Thesauruses and ontologies [en linea]. "Hipertext.net", num. 3, 2005. <http://www.hipertext.net> [Consulted: 12 feb. 2007]. 1. Introduction During the past few years, the information representation and retrieval sector in the area of Documentation and Biblioteconomy has had to assume the important repercussions of the Internet and its associated technologies, and in particular, the World Wide Web (WWW). Technological modifications arising from these important changes are leading to the gradual digitalisation of the information representation and retrieval sector, affecting information artefacts, representation and retrieval tools and user requirements. In the light of this growing context of digitalisation, diverse information representation and retrieval tools exist, which must be studied in addition to diverse fields of knowledge in which these tools have originated: Linguistics, Artificial Intelligence, Documentation, Linguistic Engineering... Hence, in specialised literature, analyses are performed on information representation and retrieval tools, taxonomies, classification systems, computational lexicons, lexical databases, thesauruses, titles lists, knowledge bases, conceptual maps, ontologies, synonym rings and semantic networks, among others. Among this wide spectrum of information representation and retrieval tools are thesauruses and ontologies, which are most often linked in bibliography, even though they come from completely different disciplinary areas. However, the conceptualisation applied by authors to the terms "thesaurus" and "ontology" is quite diverse, and sometimes authors confuse, oppose, complement or overlap both these concepts. The overall objective of the present article [ 1] is to establish the relationship between the concepts of thesaurus and ontology in the Documentation and Biblioteconomy field. Two specific objectives have been established for this purpose.

  • Phenomena of Perturbation in Electrical Systems
    Chapter 1 Phenomena of Perturbation in Electrical Systems 1.1. Electromagnetic perturbations in energy systems 1.1.1. Introduction Power electronic systems are increasingly being used in every field; initially, they were used in the industrial sector and then used increasingly in transportation, services and housing sectors. The flexibility in the control of electrical energy explains this evolution well. For the purposes of illustration, we estimate that the electrification of service or control functions in an aircraft offers the following gains1: – 10% on the mass; – 9% onCOPYRIGHTEDfuel consumption; MATERIAL – 13% on thrust from the engines; – 15% on maintenance costs; – 10% on the buying price. 1 According to SAFRAN company, symposium SPEC 2007. 2 Electromagnetic Compatibility in Power Electronics The field of automobiles is also subject to this evolution: the development of hybrid vehicles over the last 10 years and, more recently, the re-emergence of the fully electric car (while waiting for fuel cells vehicles) are evidence of this. Already, a large number of services have been electrified in thermal engine automobiles because of the flexibility of controls (speed variation) and high yield of the electrical systems: power steering, anti-blocking system (ABS), various pumps, window winders, air conditioning (to come). The introduction of this technology, as a consequence, must take into consideration its implementation constraints; electromagnetic compatibility (EMC) in particular. Indeed, static converters based on power electronics are important sources of electromagnetic perturbations that can occasionally cause malfunctions in their local or distant electronic environment: avionics, navigation systems, reception antennae, etc. Thus, it is important to understand the origin of these phenomena, their mode of propagation and the effects on their potential “victims” in order to optimize the essential reduction or protection devices necessary to conform to the standards of EMC.

B. Brodey and Todd Ramón Ochoa) This dissertation is a critical analysis and annotated translation, from Spanish into English, of the book Reglas de Congo: Palo Monte Mayombe, by the Cuban anthropologist, artist, and writer Lydia Cabrera (1899-1991). Cabrera’s text is a hybrid ethnographic book of religion, slave narratives (oral history), and folklore (songs, poetry) that she devoted to a group of Afro-Cubans known as “los Congos de Cuba,” descendants of the Africans who were brought to the Caribbean island of Cuba during the trans-Atlantic Ocean African slave trade from the former Kongo Kingdom, which occupied the present-day southwestern part of Congo-Kinshasa, Congo-Brazzaville, Cabinda, and northern Angola. The Kongo Kingdom had formal contact with Christianity through the Kingdom of Portugal as early as the 1490s.

The evidence collected is presented in the reports listed below, all of which have been reviewed by the HSE. The summary reports (the Precis and the Safety Assessment Conclusions Report) bring together all the findings of the work and should be looked to for context by all readers. The technical reports should be read in conjunction with the summary reports. While the summary reports are made as accessible as possible for general readers, the technical reports may be most accessible for readers with a degree of technical subject matter understanding.

  • Request for Input on Use of Transformer Dissolved Gas Analysis Data
    Request for Input on Use of Transformer Dissolved Gas Analysis Data CIMug Asset Health Focus Community August 2013 The CIM Users Group, in conjunction with the IEC TC57 Working Groups responsible for the CIM (Common Information Model), has established an Asset Health Focus Community, whose purpose is to develop CIM standards support for asset health. The intent is to develop use cases and requirements for a CIM standards framework to support best-of-breed practices that might include integration of data from various data sources, including operations, maintenance, and condition monitoring sources; application of analytics to this multi-faceted data set; and launching notifications and work orders. Utility input into the work of the Focus Community is crucial to the development of a high quality model, useful for solving real-world integration problems. Dissolved gas analysis (DGA) has been chosen as the first area of data model development and your assistance in providing insight into both the sources and uses of DGA data at your utility would be very much appreciated. Oil sampling for DGA 1. How frequently are DGA oil samples taken from transformers for DGA testing? (if frequency varies by type or current health of transformer, please explain) GSU’s > 10MVA: 3months GSU’s < 10MVA: 6 months Transmission Autotransformers: Yearly All other Transmission & Distribution transformers <230kV High Side: Yearly 2. What lab(s) do you utilize for DGA analysis of oil samples? Alabama Power Company has its own in-house laboratory for testing DGA samples. The data is automatically trended by the lab and notification given of out-of –limit conditions.
