Nettet6. mai 2024 · In the original sense, an instantaneous attribute is a quantity derived from what is called complex-signal analysis or complex-trace analysis. A conventional … Nettet1. apr. 2010 · 4.1.3.1 General Structure. Phase signals (PSs) are the basic elements of phase or frequency modulation and this shows their importance. They are real signals with constant instantaneous amplitude. They are characterized by a canonical pair [1, ϕ (t )] or by a unique function ϕ ( t) such that exp [ j ϕ ( t )] is an AS.
NettetInitially, 18 instantaneous attributes, 14 coherency/similarity attributes, 10 curvature attributes, and 40 frequency subband volumes of spectral decomposition were generated. In the evaluation of these seismic attributes, it was determined in the Eagle Ford interval that the highest energy resided in the 22- to 26-Hz range. NettetInitially, 20 instantaneous seismic attributes were run through a PCA analysis in a zone 20ms above and 150 ms below the top of the mapped producing reservoir. Based on these PCA results, various combinations of attributes were employed in different SOM analyses with neuron counts from 3X3, 5X5, 8X8, 10X10, and 12X12 employed for each set of …
NettetThe instantaneous measurements that are related to an analytic signal are associated with an instant of time, rather than an average over a time interval. These measurements are reliable when the seismic signal is recorded and processed so that … Nettet24. apr. 2024 · Sorted by: 5. in this piece of code, you are trying to create your flask's engine with a database URL that is on you environment variables. engine = …
