Abstract: An airfoil for a gas turbine engine includes a pressure side and a suction side that extends in a radially outward direction from a 0% span position to a 100% span position. The airfoil has a stagger angle defined as an angle between an airfoil chord and a tangential plane normal to an engine longitudinal axis. The airfoil has a relationship between stagger angle and span position that defines a curve with the stagger angle greater than 35° from 0% span to at least 50% span. The stagger angle at 100% span is greater than the stagger angle at 50% span.

Abstract: A non-etched gap is introduced along the length of an integrated Bragg grating with etched grooves such that the coupling coefficient, K, of the grating is reduced by the non-etched gap. In this way, multiple grating K values may be defined within a photonic integrated circuit using a single lithography and etch step. Additionally, the non-etched gap width may be varied along the length of a single grating to implement a chirped grating.

Abstract: When rendering a frame, e.g. that is to be used for rendering subsequent frames to be rendered, two versions of the frame are rendered, wherein the first version of the frame is rendered in its entirety but only a portion of the second version of the frame is rendered. The rendered portion of the second version of the frame is compared to a corresponding rendered portion of the first version of the frame. When the comparison determines that the two portions of the two versions match, the frame is, e.g. used for rendering subsequent frames, but when the comparison determines the two portions of the two versions do not match, an error operation is performed.

Abstract: We describe a system for determining relative changes in at least one parameter of cardiovascular function. The system provides an output showing a relative change of the parameters associated with cardiovascular function over a period of time. This relative change is between a time averaged mean of cardiovascular parameters (for each pulse within a series of pulses from an arterial blood pressure waveform data) and a baseline cardiovascular parameter value based on first and second pulses within the blood pressure waveform data. The relative change of the parameters over time is used to project a trend in the parameters associated with cardiovascular function.
