Hierarchical drilling rotation
Web1 de jan. de 2024 · Abstract. Recognition of oil well drilling activities is a crucial task as it allows for identification of nonproductive time. Activity recognition is also important as it can be part of a complete oil well monitoring system. In this paper, we propose a novel hierarchical classifier that consists of Fuzzy Rule-based (FRB) and Random Forest (RF ... WebThe 4-node membrane element with drilling DOFs (Figure 1) is derived by combin-ing the in-plane displacements using Allman-type interpolation functions (Allman, 1984) and the standard bilinear independent normal (drilling) rotation fields. De-tails of the formulation can be found in the original reference (Ibrahimbegovic,
