The present invention related to non-thermal renewable energy turbines (), in particular to the monitoring of turbine performance to identify a loss of performance indicative of faults or component degradation. The method involves comparison of measured power from a target turbine () with a predicted value for same turbine. The predicted value is calculated using the output from a plurality of other turbines () from an array and a predictive model including weightings for the other turbines () based on the strength of correlation of their historical with historical data from the target turbine ().

Turbine monitoring and maintenance

A 3-dimensional computer graphics rendering system receives object data for a scene to be rendered. This includes vertex data and index data. The scene is subdivided into priority of rectangular areas (). Objectof each rectangular area in the scene is assembled () and subsequently compressed (). This data can subsequently be retrieved and decompressed and used for producing a properly shaded and texted image for display.

Display list compression for a tiled 3-D rendering system

Disclosed are methods, apparatus () and computer readable media for rendering at least one graphic object () described by at least one edge (--) into a raster pixel image () having a plurality of scan lines and a plurality of pixel locations on each scan line. For each scan line, coordinates of intersection of those edges of the objects that intersect the scan line are determined in a predetermined order. This is preferably achieved by processing edge records () using a number of buffers () thereby enabling efficient sorting of edge intersections into order. For each adjacent pair of edge intersections, information () associated with the corresponding object is examined to determining a set of active objects () for a span of pixel locations between the corresponding pair of edge intersections. For each span of pixel locations, the corresponding set of active objects is used to determine () a value for each of the locations within the span. The information may include one or more of a fill count, a clip count and other factors. A compositing model accommodating opacity is also disclosed, as are stack operations used to facilitate rendering and other features which contribute to fast processing of image components.
