Abstract: A method of assigning categories to electronic messages is performed at a computing device having one or more processors and memory. The method includes receiving an electronic message and extracting one or more syntactic pairs of words from content of the electronic message. At least one of syntactic pairs includes a verb in a first sentence and an object in the same sentence, where the verb operates on the object. The method forms a feature vector based on the extracted syntactic pairs and uses the feature vector as input to a classifier. The classifier is trained on a set of training feature vectors, and each training feature vector is associated with a respective category. The method assigns a first category to the electronic message based on output of the classifier and displays the message in a group with other messages associated with the first category.

Abstract: The invention relates to a novel herbicide composition, which comprises the (S) enantiomer or racemate of a compound of the general formula (I), ##STR1## wherein R stands for a methyl or ethyl group, as active ingredient in an amount of 0.01 to 95% by weight together with one or more solid and/or liquid carrier(s), preferably grist(s) of native or synthetic material(s) and/or with inert solvents(s), preferably xylene(s) and/or cyclohexanone; and optionally with surface active agents(s), preferably anionic and/or nonionic emulsifying or dispersing agent(s).The invention further relates to the above compounds of the general formula (I) as well as to a process for the preparation thereof.The compounds according to the invention possess an outstanding herbicidal effect (over 90%) and advantageous selectivity threshold values against cultivated plants.

Abstract: A herbicide composition, which comprises (S)-1'-methoxycarbonylethyl 2-bromo-5-(2-chloro-4-trifluoromethylphenoxy) benzoate or (S)-1'-ethoxycarbonylethyl 2-bromo-5-(2-chloro-4-trifluoromethylphenoxy)benzoate as active ingredient in an amount of 0.01 to 95.0% by weight together with one or more solid and/or liquid carriers, preferably grists of native or synthetic materials; and/or with inert solvents, preferably xylenes and/or cyclohexanone; and optionally with surface active agents, preferably anionic and/or nonionic emulsifying or dispersing agents.

Abstract: A process for maintaining weld quality during welding operation, marking the fault spots on the workpiece and certifying of quality, in the course of which instantaneous values of arc current and arc voltage characterizing manual or mechanized welding process are continuously measured and from the values thus obtained relative short-circuit time of the arc, drop frequency and arc outputs are continuously calculated.The measured and calculated values are compared with empirically determined optimal values, thus defining absolute values and signals representing the directions of deviations, as well as duration of deviations, are compared on a predetermined span of time and averages of absolute values and signals representing the directions are defined.
