Example embodiments relate to a computer-implemented method for monitoring surge motion (101, 102) of a moored vessel (110) from successive 3D point cloud frames (210, 201, 203) of at least a rear portion of the moored vessel, the computer-implemented method comprising: determining (202), from a first 3D point cloud frame (201), an initial plane (212) indicative for a stern of the moored vessel in an initial position; determining (204), for at least one next 3D point cloud frame (203), a displaced plane (214) indicative for the stern of the moored vessel in a displaced position relative to the initial position as a result of the surge motion; affine transforming (205) the data points of the next 3D point cloud frame associated with the displaced plane onto a normal (213) of the initial plane (212); and determining (206) the surge motion of the moored vessel based on the positions (230) of the affine transformed data points along the normal (213) of the initial plane.

Example embodiments relate to a computer-implemented method for determining endurance performance of a subject based on sensor measurements; the computer-implemented method comprising: obtaining (201) a training dataset (214) comprising workload data (212) and heart rate data (211) measured, by respectively at least one workload sensor and at least one heart rate sensor, during respective physical activities performed by the subject within a historical window; training (202) a recurrent neural network, RNN (220), based on the training dataset (214); wherein the RNN (220) is configured to determine the heart rate (221) of the subject at an exerted workload (222) considering a historic time series of heart rate data (223) and workload data preceding the exerted workload; and determining (203) at least a portion of a workload-heart rate relationship (263), indicative for the endurance performance of the subject, by feeding one or more fixed workload time series (241, 242, 243) to the trained RNN (220).

A method is disclosed for plasma-based conversion of methane in a plasma reactor, the plasma reactor (1) comprising a reaction chamber and an energy source to create the plasma in the reaction chamber, the reaction chamber being fluidly connected to a post-plasma reaction chamber, the plasma reactor comprising a gas inlet, the post-plasma reaction chamber comprising a gas outlet, the method comprising: a) generating a plasma in the reaction chamber by activating the energy source; b) providing a first gas flow comprising a CH<4> component through the gas inlet and into the reaction chamber, allowing conversion of the CH<4> component into gaseous H<2> and solid carbon and allowing the continuous removal of produced H<2> through the post-plasma reaction chamber and through the gas outlet; c) in consideration of a solid carbon deposit being formed on a predetermined portion of an inner wall of the post-plasma reaction chamber, replacing the first gas flow with a second gas flow, the second gas flow comprising a COz component, allowing the oxidation of the deposited carbon, and allowing the continuous removal of produced CO through the gas outlet until the deposited carbon is substantially removed; and associated reactors and reactor systems.

Example embodiments relate to a computer-implemented method for determining endurance performance of a subject based on sensor measurements; the computer-implemented method comprising: obtaining (201) workload data measured by at least one workload sensor, comprising a time series (212) of the workload exerted by the subject during one or more physical activities; obtaining (202) heart rate data measured by at least one heart rate sensor, comprising a time series (211) of the heart rate of the subject during the one or more physical activities; selecting (203) time intervals (213 - 219) within the workload data and the heart rate data based on a set of selection criteria (204); for the respective time intervals (213 - 219), determining (205) an average workload (207) and, for a final portion of the respective time intervals (213 - 219), determining (205) an average heart rate (206); and determining (208) at least a portion of a workload-heart rate relationship (221), indicative for the endurance performance of the subject, by fitting a linear equation (224) to the average workloads and the average heart rates (230) of the respective time intervals (213 - 219).
