On somewhat e-continuity

Caldas, Miguel 25 September 2017 (has links)
A new class of functions, called somewhat e-continuous functions, has been defined and studied by making use of e-open sets. Characterizations and properties of somewhat e-continuous functions are presented.

Digital Soil Mapping of the Purdue Agronomy Center for Research and Education

Shams R Rahmani (8300103) 07 May 2020 (has links)
This research work concentrate on developing digital soil maps to support field based plant phenotyping research. We have developed soil organic matter content (OM), cation exchange capacity (CEC), natural soil drainage class, and tile drainage line maps using topographic indices and aerial imagery. Various prediction models (universal kriging, cubist, random forest, C5.0, artificial neural network, and multinomial logistic regression) were used to estimate the soil properties of interest.
