Analisis Kualitas Minyak Trafo Menggunakan Data Dissolved Gas Analysis dan Water Content
Protek: Jurnal Ilmiah Teknik Elektro, 2018 Transformer is a vital equipment in the power system. If the transformer is damage, can cause the electrical distribution to the consumer will be disrupted. Therefore, it needs special maintenance the performance of the transformer to avoid damage.

Feature Selection and Classification of Transformer Faults Based on Novel Meta-Heuristic Algorithm
Mathematics, 2022 Detecting transformer faults is critical to avoid the undesirable loss of transformers from service and ensure utility service continuity. Transformer faults diagnosis can be determined based on dissolved gas analysis (DGA).

The Turbulence Spectrum of Molecular Clouds in the Galactic Ring Survey: A Density-Dependent PCA Calibration [PDF]
, 2011 Turbulence plays a major role in the formation and evolution of molecular clouds. The problem is that turbulent velocities are convolved with the density of an observed region.

Reduced Offspring Viability Is Associated With Long-Term Stability of a Narrow Avian Hybrid Zone. [PDF]
Ecol EvolWe investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

The conjecturing process: perspectives in theory and implications in practice [PDF]
, 2007 In this paper we analyze different types and stages of the conjecturing process. A classification of conjectures is discussed. A variety of problems that could lead to conjectures are considered from the didactical point of view. Results from a number of

Diagnosing the type and location of the transformer fault by analyzing the dissolved gas using fuzzy logic [PDF]
هوش محاسباتی در مهندسی برقThere are many methods to diagnose transformer faults, including dissolved gas analysis (DGA), done in two conventional and smart ways. This paper presents a new method based on fuzzy logic and 5 DGA methods (key gas method, Durenberg's ratio method ...
