... are accustomed to using the decimal system where a whole number, p, is represented by its decimal coefficients. For example, the decimal number 253 really represents In a digital system, 253 becomes the binary number: 11111101, where Digital Resolution A digital system's resolution is determined by the number...

... of the actual tested curve. Based on the pressure derivative curve's common features among different interpretation models, an ANN approach is proposed to realize the type curves matching and move the tested curves to its sample position. Using curve's binary numbers instead of data points as input vector...

..., mainly because it describes with high effi- ciency signals of smooth curves. For the space domain, we study the local binary pattern (LBP) (Ojala et al., 2002) and the local radius index (LRI) (Zhai et al., 2013). LBP generates binary numbers in local areas according to gray-scale intensity differences...

... of single typhoons or multiple typhoons. Dong and Neumann (1983) analyzed data from 35 years, indicating that the average number of occurrences of the binary typhoons in the Pacific Northwest were 1.5 times per year, whereas the average number of occurrences in the Atlantic was 0.33 time. Nowadays...

..., number of epochs, and the size of the data set. For a completion engineer, the answer to the question of whether or not a well will require sand production control is binary-either a well will produce sand or it does not. Support vector machines (SVM) are known to be better suited as the machine-learning...

In this method, the corrosion profile, which represents the number, locations, and shapes of plural corrosion areas on the steel matrices, is modeled into a binary string instead of a set of unknown parameters. The binary string is defined by discretizing the steel matrices...
