Abstract: A device is provided for monitoring the compaction of concrete introduced into a slipform of a slipform paver by means of at least one concrete compacting device that has an asynchronous motor for driving an unbalanced mass which generates vibrations. The monitoring device comprises an apparatus for monitoring the stator current of the asynchronous motor, the apparatus being configured such that a change in the compaction of the concrete is determined based on an analysis of the stator current. The apparatus for monitoring the stator current of the asynchronous motor is preferably configured such that the amplitude spectrum of the stator current is determined in order to analyse the stator current. It is advantageous that the compaction of the concrete is not monitored using sensors which are exposed to harsh ambient conditions during operation of the slipform paver.

Abstract: A connector insert arrangement, an active optical cable and methods are described. The connector insert is receivable in a connector housing for removable engagement with a complementary connector. Dielectric inserts each support one or more electrical contacts for access by the complementary connector and each electrical contact is selected as one of a contact pad and a spring probe pin for electrical contact with a complementary spring probe pin and complementary contact pad, respectively, in the complementary connector. A ground body supports the dielectric inserts to maintain a characteristic transmission line impedance along each of a plurality of high speed data paths such that each high speed data path serves as an independent transmission line structure that provides a data transfer rate of at least 1 gigabit per second. An active optical cable is described that can be hermaphroditic.

Abstract: The invention relates to a catalyst composition comprising a salt of a non- or weakly coordinating anion, said non- or weakly coordinating anion comprising at least one metal or metalloid ion M with valency v+, v representing an integer between 1 and 5, and at least one bidentate ligand coordinating to this metal or metalloid ion, and a catalyst that can be activated by said non- or weakly coordinating anion, characterized in that said bidentate ligand is a bidentate monoanionic ligand of formula (I): (R1qA1-X-A2R2r), wherein X represents a bridging moiety; A1 and A2 are each independently chosen from the group comprising N, O, P, S, and C; R1 and R2 are each independently chosen from the group comprising an optionally substituted linear or branched (hetero)alkyl group, an optionally substituted (hetero)aryl group, and a Si containing group; and q and r each independently represent an integer with 0?q, r?2.

Abstract: The present invention relates to means and a method executable by a computer system for navigation within a tree structure with leaf nodes representing arbitrary types of objects, i.e. of related data treated as a unit. According to the current teaching a travel point representation step is suggested, wherein after selection of at least one non-leaf node as travel point only the path and non-leaf nodes in said tree structure from said travel point to the root of said tree structure is represented in a tree view area. Moreover the complete sub-tree of said travel point is represented in said tree view area. In addition or alternatively after selection of said travel point, a travel box is represented for said travel point, said travel box representing object identifications of all objects of all leaf nodes in said sub tree of said travel point.

Abstract: This mechanism relates to a method within the area of information mining within a multitude of documents stored on computer systems. More particularly, this mechanism relates to a computerized method of generating a content taxonomy of a multitude of electronic documents. The technique proposed by the current invention is able to improve at the same time the scalability and the coherence and selectivity of taxonomy generation. The fundamental approach of the current invention comprises a subset selection step, wherein a subset of a multitude of documents is being selected. In a taxonomy generation step a taxonomy is generated for that selected subset of documents, the taxonomy being a tree structured taxonomy hierarchy. Moreover this method comprises a routing selection step assigning each unprocessed document to the taxonomy hierarchy based on largest similarity.

Abstract: A description is given of a process for the transesterification of carboxylic esters, characterized in that the catalyst used is a tin(IV) compound comprising a radical of the formula bound to an inorganic support, where L is an at least divalent radical and at least one of the free valences of the Si in formula (I) is bound to the inorganic support, novel tin(IV) compounds and their preparation.
