    摘要: Predicting a drill string stuck pipe event. At least some of the illustrative embodiments are methods including: receiving a plurality of drilling parameters from a drilling operation; applying the plurality of drilling parameters to an ensemble prediction model comprising at least three machine-learning algorithms operated in parallel, each machine-learning algorithm predicting a probability of occurrence of a future stuck pipe event based on at least one of the plurality of drilling parameters, the ensemble prediction model creates a combined probability based on the probability of occurrence of the future stuck pipe event of each machine-learning algorithm; and providing an indication of a likelihood of a future stuck pipe event to a drilling operator, the indication based on the combined probability.

    摘要: A piezoelectric component includes an electromechanical transducer with two first electrodes and a second electrode. The second electrode is arranged between the two first electrodes. The transducer also includes a first main side, a second main side, opposite from the first main side, and a first longitudinal side. A first contiguous metallization layer is arranged on a first partial region of the first main side and on a partial region of the first longitudinal side adjacent to the first partial region of the first main side. Here, the partial region of the first longitudinal side is kept at a sufficient distance from a side edge facing the second main side and the partial region electrically contacts the at least two first electrodes.
