Strength and failure modes of rock mass models with non-persistent joints
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
Most problems faced by the practicing rock engineer involve the evaluation of rock mass strength and deformability. The theoretical evaluation of the mechanical properties of fractured rock masses has no satisfactory answer ...
Safety, reliability and economics in mining systems
(IEEE, 2006)
Events, incidents, accidents, failures, production losses, life reduction of equipment, casualties, and insurance coverage are all critical topics with respect to safety, reliability, and economics. This paper identifies ...
Improving the Robustness of Distributed Failure Detectors in Adverse Conditions
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
Failure detection is at the core of most fault tolerance strategies, but it often depends on reliable communication. We present new algorithms for failure detectors which are appropriate as components of a fault tolerance ...
Failures by SCC in buried pipelines
(Pergamon-Elsevier Science Ltd, 2002-10)
Until a few years ago there had been no record of stress corrosion cracking (SCC) as a main cause of failures in Argentine pipelines, but as the pipeline system became of a certain age this mechanism started to have an ...
Análise de dados de vida aplicado a instrumentos com função OCR (Optical Character Recognition) instalados em rodovias brasileiras
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia ElétricaUTFPR, 2018-12-04)
This paper presents an investigation on reasons of failure and its frequency in instruments with OCR (Optical Character Recognition) function. For that, the system was considered unrepairable, and it was used the life data ...
Electromechanical Device for Temperature Control of Internal Combustion Engines
(IOP Publishing Ltd, 2019-11-25)
Internal combustion engines are the most commonly used engines in the automotive world. However, these engines lack an overheating prevention system against cooling system failures when they exceed their normal operating ...
Risk analysis in low-voltage distribution systems
(SAGE Publications Ltd, 2019)
© IMechE 2018. Electric power distribution is a complex network involving technical challenges from a wide range of sources, a considerable degree of risk and substantial financial resources. Design and maintenance strategies ...
Early warning mechanism for power system large cascading failures
(IEEE, 2012)
As the interconnection of power grids, failure of single component could propagate out, and because of the scale of the power system, it is almost impossible to analysis all failure patterns. Traditional methods for online ...
Prognosis and Detection of Experimental Failures in Open Field Diesel Engines Applying Wienerˈs Artificial Immunological Systems
(2021-12-01)
The high costs of open-field diesel engines arise from the lack of maintenance of these systems. Thus, the maintenance of this equipment has been treated as a great challenge, as some methods of data monitoring are not ...
