Abstract: A method of modifying a speech signal generated by a text-to-speech synthesiser, the method comprising: receiving a text signal; generating a speech signal from the text signal; deriving a control feature vector, wherein the control feature vector represents modifications to the speech signal; inputting the control feature vector in the text-to-speech synthesiser, wherein the text-to-speech synthesiser is configured to generate a modified speech signal using the control feature vector; and outputting the modified speech signal.

Abstract: A method includes determining a plurality of data points, determining a distance between each data point and each of the other plurality of data points, choosing a first one of the plurality of data points, identifying all of the other plurality of data points within a maximum distance of the chosen data point, repeating steps the previous steps to choose a different one of the plurality of data points until all of the data points have been chosen, identifying one or more clusters each having a predefined minimum number, K, of data points within a predefined search radius and analyzing the one or more clusters with respect to K linkages.

Abstract: This invention relates to a method of preparing a spray tank mix of glyphosate comprising (a) providing glyphosate acid concentrate; (b) providing an alkaline composition; and (c) forming a mixture of glyphosate acid concentrate and alkaline composition in the spray tank by addition of a composition comprising the glyphosate acid concentrate to a diluted aqueous mixture of the alkaline composition.

Abstract: The invention relates to an aqueous concentrate for agricultural use for dilution and spray application to soil or plant material comprising at least about 25% by weight activated carbon and a method of greening turf using the composition.

Abstract: Magnetically attractable particles comprise a core of magnetic material encapsulated in a metal oxide coating. They may be made by emulsifying an aqueous solution or dispersion of the magnetic material or precursor, and an aqueous solution or sol of a coating inorganic oxide or precursor, in an inert water-immiscible liquid. The aqueous droplets are gelled, e.g. by ammonia or an amine, recovered, and heated at 250.degree.-2000.degree. C. The resulting particles are generally smooth spheres below 100 microns in diameter and often of sub-micron size.
