Abstract: A method for evaluating metrics associated with isolated execution environments utilized for synthetic monitoring of a web application and modifying the quantity of isolation execution environments hosted by a particular hosting service at a particular geographic location based on the metrics. The method can include receiving an instruction to monitor computing resources at the particular geographic location; obtaining configuration data for the particular geographic location; communicating a request to the particular hosting provider for an identification of a collection of isolated execution environments that are instantiated at the particular geographic location; obtaining metrics associated with the collection of isolated execution environments; evaluating the metrics against the set of scaling criteria; and/or generating an instruction for the particular hosting provider to modify the quantity of the collection of isolated execution environments.

Abstract: An air traffic display aid and method that uses parameters for defining a heading for an alpha approach and a beta approach. These can be intersecting or converging runways, dependent or independent parallel runways or airways in en-route configurations. A target reference point is determined in dependence upon the alpha and beta approaches. And an image reference point is determined in dependence upon at least one of the target reference point, a difference between the headings, a characteristic of the beta approach and an offset. Single target mirror ghosting, in-trail ghosting on demand, associated configurations and user selectable resynchronization spacing is also supported.

Abstract: A frequency modulated continuous wave (FMCW) radar is described that comprises a frequency sweep generator (42) for producing a swept frequency signal. A discriminator (52) receives a portion of the swept frequency signal and produces a reference difference-frequency signal. The discriminator 52 comprises an optical delay means, which may comprises a laser diode (72), an optical fibre (74) and a detector (76) for producing a time displaced frequency swept signal from which the difference-frequency signal is derived. A transceiver (50) is also described that generates the signal to be transmitted by the radar from the swept frequency signal and produces a target difference-frequency signal. An analogue-to-digital converter (80) samples the target difference-frequency signal at a rate derived from the frequency of the reference difference-frequency signal. Use of the radar in various applications, such as detecting foreign object debris on airport runways and perimeter security, are also described.

Abstract: Employee performance in a call center or similar complex work environment is managed by selecting a controlled number of performance criteria from among numerous possible performance criteria, establishing performance goals for the selected performance criteria, communicating the goals to the call center employees, monitoring the actual performance of the employees in relation to the performance goals, and reporting the performance of the employees in relation to the performance goals to the employees, management or both.
