Abstract: In an example embodiment, motion is detected with an IMU utilizing standard deviation. Specifically, an IMU may obtains IMU measurements. An IMU motion detection process may accumulate a particular number of IMU measurements over a time interval to calculate an absolute magnitude of earth rate (ERimu) value and an absolute magnitude of normal gravity value (GNimu). The values calculated may be referred to as a sample. The IMU motion detection process may create sample rolling histories based on a particular number of samples, e.g., consecutive samples. The IMU motion detection process may then calculate standard deviation values for a sample rolling history based on the ERimu and GNimu values included in the sample rolling history. The IMU motion detection process may compare the standard deviation values to respective motion threshold values, which may be adaptive, to determine if a body of interest, e.g., vehicle, is moving or is stationary.

Abstract: Broadly speaking, embodiments of the present techniques provide methods for inspecting a neural network, such that a neural network can be made more transparent. The inspection is performed with respect to each decision or output made by the neural network. The method comprises outputting a dependency graph, for each inspection/decision. Each dependency graph shows which neurons are used to make each individual decision made by the neural network, and how those neurons interact with or relate to each other. Specifically, the dependency graph shows the dependencies between neurons in adjacent layers. By understanding which neurons are used to make individual decisions, and the dependencies between neurons, the neural network can be better understood, audited, optimised, and debugged, for example.

Abstract: Disclosed is a method for detecting and identifying toxic and harmful gases based on machine olfactory. Information about the toxic and harmful gases is firstly collected through the machine olfactory system and then analyzed through a Selected Linear Discriminate Analysis (SLDA) combined with a Markov two-dimensional distance discriminant method to identify various toxic and harmful gases. The algorithm disclosed in the invention extracts the characteristic information of the sample data, and then fast processes and identifies the information as a linear recognition algorithm does, having wide applications in the field of machine olfaction, especially in detecting and identifying the toxic and harmful gases in real-time based on machine olfaction. The algorithm involves low complexity and high recognition efficiency.
Abstract: System and methods of controlling diverter placement during stimulation treatments are provided. Data relating to at least one downhole parameter is obtained for a current treatment stage within a subsurface formation. A response of the diverter to be injected during a diversion phase of the current stage on the downhole parameter is estimated, based on the obtained data and a diagnostic data model. Values for diversion control parameters are calculated, based on the estimated response. As the diverter is injected into the formation, an actual response of the diverter is monitored. Upon determining that a difference between the actual and estimated response exceeds an error tolerance threshold, the model is updated. The model is further updated over subsequent iterations of the diversion phase when the actual response is less than the estimated response. Subsequent diversion phases are performed over a remainder of the current stage, based on the updated model.
