Gas Production by Monoester of Saturated Fatty Acids under Electrical Fault
Jurnal Nasional Teknik Elektro, 2022 This paper deals with the gas production by monoester oil intended to be used as insulating oil under an electrical discharge of low energy. The monoester contains only saturated fatty acids in its hydrocarbon chain. The electrical fault was realized by

Journal of Renewable Energy, Electrical, and Computer Engineering, 2022 The power transformer would have happened disturbanced that can cause a failure at a transformer. For this condition needed to maintenance power transformer, one of which is by analyzing transformer oil by using the TDCG method. This analysis is carried out to determine the diagnosis of faults in the transformer.

A Simple and Efficient Regularization Method for 3D BEM: Application to Frequency-Domain Elastodynamics [PDF]
, 2005 An efficient and easy-to-implement method is proposed to regularize integral equations in the 3D boundary element method (BEM). The method takes advantage of an assumed three-noded triangle discretization of the boundary surfaces.

Simplicial and Cellular Trees [PDF]
, 2015 Much information about a graph can be obtained by studying its spanning trees. On the other hand, a graph can be regarded as a 1-dimensional cell complex, raising the question of developing a theory of trees in higher dimension.
