The main theorem of this paper is a generalisation of well known results about Dehn surgery to the case of attaching handlebodies to a simple 3–manifold. The existence of a finite set of ‘exceptional’ curves on the boundary of the 3–manifold is established. Provided none of these curves is attached to the boundary of a disc in a handlebody, the resulting manifold is shown to be word hyperbolic ...

Emerging Web standards promise a network of heterogeneous yet interoperable Web Services. Web Services would greatly simplify the development of many kinds of data integration and knowledge management applications. Unfortunately, this vision requires that services provide large amounts of semantic metadata “glue”. As a first step to automatically generating such metadata, we describe how machin...

A dynamic method for mass detection, considering attaching positions of micro-objects on microcantilevers, is introduced. Two models based on the Rayleigh– Ritz method were developed for analyses of the first flexural and the first torsional modes of a “cantilever– mass” system, respectively. Due to one-to-one correspondence between the longitudinal adhering positions of the micro-objects and t...
