13. Monitoramento permanente de motores de indução trifasicos / On-line monitoring of three-phase induction motors
A predictive maintenance program must include several techniques of monitoring of the electric motors conditions. Among these techniques, probably the two most classic ones are related to electric current and vibration analysis. Unfortunately, in both cases inherent drawbacks make difficult their use in loco on industry plants. As there is a large range of

14. Curvas típicas de carga para o planejamento operacional do sistema de distribuição. / Typical load curves for operational planning of distribution systems.
This dissertation presents and validate a load characterization framework for the operational planning of electric distribution networks based on characterization of customer typical load curves. The pattern recognition of typical load curves was based on the usage of self organizing maps, a type of neural network, over the huge database of customer field me

15. Uma arquitetura híbrida para descoberta de conhecimento em bases de dados: teoria dos rough sets e redes neurais artificiais mapas auto-organizáveis. / An hybrid architecture for the knowledge discovery in databases: rough sets theory and artificial neural nets self-organizing maps.
Databases of the real world contain a huge amount of data within which several relations are hidden. These relations are difficult to discover by means of traditional methods such as worksheets and operational informative reports. Therefore, the knowledge discovery systems (KDD) appear as a possible solution to extract, from such relations, knowledge to be a

16. Common information Model/eXtensible Markup Language (CIM/XML) to exchange data among Power Utilities Control Centers. / Common Information Model/eXtensible Markup Language (CIM/XML) na troca de informações entre centros de controle de energia elétrica.
This dissertation provides an analysis about the application of a data model based on IEC 61970 (CIM) standard a tool for exchanging operational and equipments information among different Electrical Power Utilities computing systems. The purpose of this standard is to create a mechanism for information exchange using XML, called CIM/XML a format specif

18. Proposta de um sistema integrado de gestão em segurança de tráfego - SIG SET.
This work presents a management tool that can be of great utility to private or governmental organizations, mainly the ones which are really considered to deal with the transit in a new, modern, efficient, efective and, over all, responsible way. For this, it makes use of modern computational techniques, as is the case of Geographic Information System - GIS,

19. Modelagem de dados para planejamento e gestão operacional de transportes. / Data modeling for transportation planning and operations management.
The integration of urban transportation systems management activities, at all levels, pertaining one entity, is highly desirable. Integration across entities is also important when their plans or transportation systems overlap, as usually happens in urban agglomerations. In order to achieve consistent plans among these entities, information must be shared. T

20. Medicare charges and the operational-year coding concept.
The introduction by the Health Care Financing Administration, in 1993, of separate conversion factors for "medical" and "surgical" services to be used in calculating Medicare charges would ordinarily necessitate the use of year-specific software source code. By designing the system to utilize macro-substitution of the year in the names of Current Procedural

21. Data sharing and dissemination strategies for fostering competition in health care.
OBJECTIVES: To introduce the concept of common models for data sharing and dissemination, highlight the current operational, technical, and political issues surrounding existing data sharing and dissemination initiatives in a health care market, and suggest an ideal model for future data initiatives. DATA SOURCES/STUDY SETTING: A literature review and case s

22. Electronic document delivery using the Internet.
The Health Sciences Libraries Consortium (HSLC) was established in 1985 by thirteen founding member institutions in Pennsylvania and Delaware. In 1989, the Interlibrary Loan, Document Delivery, and Union List Task Force, appointed by the HSLC Board of Directors, successfully demonstrated the feasibility of supplying 94% of all interlibrary loan (ILL) photoco

24. Generic data modeling for clinical repositories.
OBJECTIVE: To construct a large-scale clinical repository that accurately captures a detailed understanding of the data vital to the process of health care and that provides highly efficient access to patient information for the users of a clinical information system. DESIGN: Conventional approaches to data modeling encourage the development of a highly spec
