Being one of the most expensive components of an electrical power plant, the failures of a power transformer can result in serious power system issues. So fault diagnosis for power transformer is highly important to ensure an uninterrupted power supply. Due to information transmission mistakes as well as arisen errors while processing data in surveying and monitoring state information of transf...

According to intelligent complementary ideas, a new transformer fault diagnosis method is proposed based on rough set (RS) and Bayesian optimal classifier in this paper. Through RS reduction, the diagnostic decision table is simplified and fault symptoms information is compressed, and the minimal decision rules can be obtained. In light of the minimal decision rules, the complexity of Bayesian ...

In the context of offshore outsourcing, in order to validate the requirements of a stakeholder (the contractor) against the actual behavior of an implementation under test (IUT) developed by the contracted, it is necessary to have a requirement specification language from which test cases can be generated and executed on an actual IUT. Code-based testing tools are limited to unit testing and do...

Background INVESTIGATE-I (INVasive Evaluation before Surgical Treatment of Incontinence Gives Added Therapeutic Effect?) was a mixed methods study to assess the feasibility of a future randomised controlled trial of invasive urodynamic testing (IUT) prior to surgery for stress urinary incontinence (SUI) in women. Here we report one of the study's five components, with the specific objectives of...

Although in utero transplantation (IUT) has been shown to be effective in treating human severe combined immune deficiency (SCID), the relative merit of IUT as compared with postnatal bone marrow transplantation (BMT) for SCID is unknown. Therefore, comparative studies were undertaken in mice to determine the engraftment outcome in these two settings. Because T-cell depletion (TCD) reduces graf...

AIMS To determine surgeons' views on invasive urodynamic testing (IUT) prior to surgery for stress (SUI) or stress predominant mixed urinary incontinence (MUI). METHODS Members of British Society of Urogynaecology (BSUG) and British Association of Urological Surgeons Section of Female, Neurological and Urodynamic Urology (BAUS-SFNUU) were sent an email invitation to complete an online "Survey...

Tools for Model-Based Testing (MBT) use various algorithms and strategies to generate tests from a behavioral model of the IUT. Existing MBT tools are based on formal, typically state-based, specification languages. In state-of-theart MBT tools, which we briefly review, executable tests are generated. But these tests are not directly traceable to an actual implementation-under-test (IUT). Inste...

In order to check the conformance of an IUT (implementation under test) with respect to a specification, it is not feasible, in general, to test the whole set of IUT available behaviors. In some situations, testing the behavior of the IUT assuming that it is stimulated by a given usage model is more appropriate. Specifically, if we consider that specifications and usage models are defined in pr...

Energization of a transformer results in sudden flow of current which is an effect of core magnetization. This current will be dominated by the presence of second harmonic, which in turn is used to segregate fault and inrush current, thus guaranteeing proper operation of the relay. This additional security in the relay sometimes obstructs or delays differential protection in a specific scenario...
