    摘要： A method and apparatus is disclosed herein for antenna element placement are disclosed. In one embodiment, an antenna comprises an antenna feed to input a cylindrical feed wave; a single physical antenna aperture having at least one antenna array of antenna elements, where the antenna elements are located on a plurality of concentric rings concentrically located relative to an antenna feed, wherein rings of the plurality of concentric rings are separated by a ring-to-ring distance, wherein a first distance between elements along rings of the plurality of concentric rings is a function of a second distance between rings of the plurality of concentric rings; and a controller to control each antenna element of the array separately using matrix drive circuitry, where each of the antenna elements is uniquely addressed by the matrix drive circuitry.

    摘要： The invention relates to a vane (10) of a diffuser (5) for a radial or mixed-flow compressor (2) of an engine (1), including a leading edge (11) arranged facing a flow of gas, a trailing edge (12) being opposite the leading edge (11), a side upper surface wall (13) and a side lower surface wall (14) which connect the leading edge (11) to the trailing edge (12), and a profile including a curved line (15) having at least two points of inflection (I1, I2) between the leading edge (11) and the trailing edge (12). The invention also relates to a corresponding radial diffuser (2).

    摘要： A mechanism is described for facilitating efficient processing of graphics commands at computing devices. A method of embodiments, as described herein, includes detecting a current object representing a bundled state of graphics commands in a command list to be processed at a graphics processor of a computing device, and evaluating the current object to determine a previous object bound to a first set of the graphics commands, where the first set of the graphics commands is associated with a first command state corresponding to the previous object. The method may further include copying a second set of the graphics commands to a command buffer associated with the command list, where the second set of the graphics commands represents a remainder of the graphics commands in the command list upon excluding the first set of the graphics commands. The method may further include facilitating the graphics processor to execute the second set of the graphics commands from the command buffer.
