Abstract: A computer-implemented system and method for tuning photovoltaic power generation plant forecasting is provided. Global horizontal irradiance (GHI), ambient temperature and wind speed for a photovoltaic power generation plant over a forecast period are obtained. Simulated plane-of-array (POA) irradiance is generated from the GHI and the plant's photovoltaic array configuration as a series of simulated observations. Inaccuracies in GHI conversion are identified and the simulated POA irradiance at each simulated observation is corrected as a function of the conversion inaccuracies. Simulated module temperature is generated based on the simulated POA irradiance, ambient temperature and wind speed. Simulated power generation over the forecast period is generated based on the simulated POA irradiance, simulated module temperature and the plant's specifications and status.

Abstract: Method and system for 3-D imaging of subterranean geologic structures based on seismic data interpretations involves correcting mis-ties that arise as a result of orthogonal polylines failing to intersect due to inconsistencies in seismic interpretations. In some embodiments, the mis-ties may be corrected by adding a data point from one polyline at or near the mis-tie to the other polyline, and vice versa for the other polyline. The two data points are then adjusted so they coincide or merge. The merged data point is then used as intersection points for the polylines and associated with one another such that a change made to one intersection point is automatically made to the other intersection point. In some embodiments, one or more neighboring data points on each polyline are adjusted to smooth out the polyline at the point of the corrected mis-tie.

Abstract: In some embodiments, a seismic processing method comprises assembling a specularity gather by determining a specularity value at each of a plurality of subsurface locations, and summing trace amplitudes into a plurality of bins, each bin characterized by a range of specularity values. The specularity value at a subsurface location is computed according to an angle between a normal to a local reflector and a direction of a total (source+receiver) traveltime gradient. For example, the specularity may be proportional to (e.g. equal to) a magnitude of the cosine of the angle. A diffraction image may be generated by summing specularity gather data over specularity, with specular event amplitudes attenuated relative to diffractive event amplitudes.

Abstract: There is provided a speed monitoring device which can use a low resolution position sensor and provide a high speed response without false detection. The speed monitoring device stores, in a memory unit, a permitted margin PM, a comparison distance VC which is a maximum movement distance permitted for a moving element within one cycle period, and positional data P(t?nT) (n is a natural number equal to or less than M) of the moving element obtained from the present time t to M cycles ago. During speed determination, whether |P(t)?P(t?nT)|>VC*n+PM holds true is determined for every integer n from 1 to M. When the inequality holds true, it is determined that the speed exceeds the speed limit.

The method includes identifying some of the distance measurements as spline measurements associated with splines of the clutch hub. The roundness of the clutch hub is calculated based on the spline measurements.
