Transformers are playing an increasingly significant part in energy conversion, transmission, and distribution, which link various resources, including conventional, renewable, sustainable energy, from generation to consumption. Power transformers their components vulnerable operational factors during entire life cycle, may lead catastrophic failures, irreversible revenue losses, power outages....

To ensure the conformance of an implementation under test (in the following IUT) with respect to a specification requires, in general, the application of an infinite number of tests. In order to use finite test suites, most testing methodologies add some feasible hypotheses about the behavior of the IUT. Since these methodologies are designed for considering a fix set of hypotheses, they usuall...

Several problems in stochastic analysis are defined through their geometry, and preserving that geometric structure is essential to generating meaningful predictions. Nevertheless, how design principled deep learning (DL) models capable of encoding these structures remains largely unknown. We address this open problem by introducing a universal causal DL framework which the user specifies suita...

The Intersection-Union Test (IUT ) has become increasingly popular, especially through its application in bioequivalence testing. Here we will provide a basic introduction and discuss some properties of the IUT . Since this method is based upon a combination of tests, there may be a concern for the need of a multiplicity adjustment to adequately control the overall type-I error rate. We will ad...

For k = 1; : : : ; p, let t k denote the time points at which dissolution prooles are collected , and let X ik and Y jk represent the proportion of drug dissolved from dosage unit i for the reference drug and for dosage unit j for the test drug respectively, We assume that the samples are drawn from independent multivariate p normal populations with mean vectors X and Y respectively and the sam...

With the expansion of use frequency response analysis (FRA) as a reliable tool for fault detection in transformers, more capabilities this method are discovered every day. So that today number transformer faults can be identified by FRA has also increased. One most critical steps with is to distinguish and classify them different classes. In paper, well-known intelligent classifiers (probabilis...

The normal operation of the transformer is an important guarantee for safe whole power network. Usually, periodic maintenance work increases workload and personnel. In this paper, intelligent predictive system dry-type based on vibration proposed to monitor state transformer. fractional-order Kalman filter normalization method are used preprocess data reduce noise interference, then fault class...
