Abstract: A method of improving accessibility for the user operation of a first application on a computer includes the steps of taking one or more measurements of a current user's interaction with an application on the computer, comparing the one or more measurements with expectations derived from measurements from a first corpus of users, characterising one or more needs of the current user based upon the comparison, and modifying at least a first property of the first application responsive to the characterised need or needs.

Abstract: The present invention relates to compounds which are of use in the field of agriculture as herbicides. The invention also relates to methods of using said compounds and compositions comprising said compounds.

Abstract: The present invention relates to compounds which are of use in the field of agriculture as herbicides. The compounds in question are of formula II and comprise a spirofused tricycle core: wherein R4 and R5 together with the carbon atom to which they are attached form a cyclic group.

Abstract: A method of characterizing an optical system, wherein the optical system comprises an optical fibre having a proximal end and a distal end, wherein the optical fibre comprises a non-single-mode optical fibre, and comprising a reflector assembly comprising a stack of reflectors disposed at the distal end of the optical fibre, wherein the stack of reflectors is arranged to provide different reflector matrices in dependence on illumination wavelength. The method comprises projecting calibration patterns at a plurality of characterization wavelengths onto the proximal end, then obtaining, at the proximal end, data relating to reflected calibration patterns. An instantaneous transmission matrix of the optical fibre is then determined using the data relating to the reflected calibration patterns and the reflector matrices.

Abstract: The invention relates optical devices, for example pixelated devices such as an optical device having a plurality of coloured pixels, each said pixel comprising a filter structure, the filter structure comprising: a first metallic layer; a dielectric layer over said first metallic layer; and a second metallic layer over said dielectric layer; wherein said second metallic layer comprises a nanostructured metallic layer having a lateral structure with features having at least one characteristic lateral dimension equal to or less than 1 ?m, and wherein said second metallic layer is structured to couple light incident on said second metallic layer into at least two absorption modes of the filter structure, one to either side of a target wavelength, such that said filter structure appears coloured at said target wavelength in reflected or transmitted light.

Abstract: A method is provided of producing an optical filter. The method comprises depositing a first mirror layer onto a substrate; depositing an insulating layer on the first mirror; exposing at least some of a plurality of portions of a surface of the insulating layer to a dose of energy; developing the insulating layer in order to remove a volume from the at least some of the plurality of portions of the insulating layer, wherein the volume of the insulating layer removed from each portion is related to the dose of energy exposed to each portion, and wherein a remaining thickness after the removal of the volume from each portion of the insulating layer is related to the dose of energy exposed to each portion. The method further comprises depositing a second mirror layer on the remaining thickness of each of the plurality of portions of the insulating layer.

Abstract: Measures, including methods, apparatuses and non-transitory computer-readable storage media, associated with network orchestration. A model of a physical resources part of a network and a model of a virtualised resources part of the network are obtained. The physical/virtualised resources part of the network includes a plurality of physical resources/at least one virtualised network function and represents dependencies between different physical/virtualised resources in the physical/virtualised resources part of the network. At least one optimisation operation is performed using the models of the physical and virtualised resources parts of the network to identify an optimised mapping of the at least one virtualised network function onto at least one of the plurality of physical resources. The at least one virtualised network function is instantiated on the at least one of the plurality of physical resources based on the identified optimised mapping.
