When drilling conventionally, upon indication of an influx, the drill string is lifted off bottom, circulation is stopped, a flow check is performed, and if the well is flowing, the well is shut in. The influx is then circulated out through rig choke using a reduced circulating rate. With...
A matrix is a set of number, symbols and expressions that are arranged into rows and columns. When the matrix has expression or symbols, it can be solved by using algebra and the rules of matrices.Answer and Explanation: Matrix algebra is when there are unknown variables such as an "x" ...
Scalar multiplication is easy. Matrix multiplication, however, is quite another story. In fact, it's a royal pain in the hindquarters. What is matrix multiplication? Matrix multiplication is the process of multiplying one matrix by another matrix, when such multiplication is well-defined — that ...
Here is a step-by-step guide on how to manually calculate a Confusion Matrix. Define the outcomes The first step will be to identify the two possible outcomes of your task: Positive or Negative. Collecting the predictions Once your possible outcomes are defined, the next step will be to col...
