Mechanical vibrations of the RHIC IR triplets has been identified as the dominant source of horizontal orbit jitter in the frequency domain below 20 Hz. Results of detailed measurements are be reported to characterize these effects.

Ground motion studies have been performed at DESY for more than a decade, covering beam motion in the two-ring e-p collider NEW, luminosity preservation in Linear Colliders, and active stabilization methods. An overview of past and present activities will be given.

The transition of the World Wide Web from a paradigm of static Web pages to one of dynamic Web services provides new and exciting opportunities for bioinformatics with respect to data dissemination, transformation, and integration. However, the rapid growth of bioinformatics services, coupled with non-standardized interfaces, diminish the potential that these Web services offer. To face this challenge, we examine the notion of a Web service class that defines the functionality provided by a collection of interfaces. These descriptions are an integral part of a larger framework that can be used to discover, classify, and wrapWeb services automatically. We discuss how this framework can be used in the context of the proliferation of sites offering BLAST sequence alignment services for specialized data sets.
