The management of firewalls in today’s enterprise network environment is a complex and error-prone task. Effective techniques and tools for administrating the firewall configurations should be available to network administrators. In this paper, we present such a technique by using the geometry technology to model the firewall configurations. Each filtering rule is mapped onto a hyperspace objec...

Recent developments in combinatorial synthesis and in High Throughput Screening (HTS) have given an impulse to research in new areas of analytical chemistry [1], or have A set of 114 olfactory molecules divided into fruity, ethereal and camphoraceous compounds, was submitted to an analysis by Kohonen Neural Networks, also known as Self Organising Map (SOM). The compounds are represented in a hy...

We show that a measurement μ on a continuous dcpo D extends to a measurement μ̄ on the convex powerdomain CD iff it is a Lebesgue measurement. In particular, kerμ must be metrizable in its relative Scott topology. Moreover, the space ker μ̄ in its relative Scott topology is homeomorphic to the Vietoris hyperspace of kerμ, i.e., the space of nonempty compact subsets of kerμ in its Vietoris topolog...

The aim of appraisal theory in the psychology of emotion is to identify the features of the emotion-eliciting situation that lead to the production of one emotion rather than another. A model of emotional appraisal takes the form of a set of dimensions against which potentially emotion-eliciting situations are assessed. The dimensions of the emotion hyperspace might include, for example, whethe...

In this paper, we present a technique called bookmark per Web page by which users can build a new link structure in a hypermedia. It allows users to create their own links for Web pages. Our aim is to provide an adaptive hypermedia with additional adaptive features by considering properties which the author of the hyperspace did not provide when the hyperspace was designed. In addition, a gener...

Abstract We consider infinite-dimensional properties in coarse geometry for hyperspaces consisting of finite subsets metric spaces with the Hausdorff metric. see that several are preserved by taking hyperspace at most n points. On other hand, we prove that, if a space contains sequence long intervals coarsely, then its is not coarsely embeddable into any uniformly convex Banach space. As coroll...
