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.

Analysis of Transformer Conditions using Triangle Duval Method
IOP Conference Series: Materials Science and Engineering, 2018 Abstract Electrical or thermal failure that occurred in the transformer oil can produce a dangerous gas called gas fault. By indicating the content of dissolved gases in the transformer oil, can be obtained information about what happened to the oil so it can be estimated indication of the type and cause of the failure in the transformer.
