    摘要： An optical fibre including a waveguide and at least one stress applying region is described. The waveguide is defined by a numerical aperture, and the stress applying region is defined by a depressed refractive index. The optical fibre is configured such that the waveguide supports at least two polarised fundamental modes, two polarized first second-order modes, and two polarised second second-order modes. The waveguide includes comprises a gain medium. The stress applying region, the waveguide and the disposition of the gain medium are such as to provide preferential guidance to at least one of the modes at an operating wavelength.

    摘要： A method is described for monitoring a plurality of process instances, such as business process instance. The method comprises: providing a model object reflecting a workflow common to the process instances, the model comprising a plurality of nodes with at least some of the nodes being capable of assuming at least active and blocked states; receiving events and changing the states of the nodes in corresponding model object instances in accordance with the events received so as to reflect the status of the process instances, repeatedly determining an “at risk” state indicator for the model instances, the “at risk” state indicator when set for a model instance indicating that the corresponding workflow instance is in a state in which it cannot progress to a normal completion without encountering a node in the blocked state.
