ATM network is a flexible environment to provide efficient transport of multimedia traffic. MPEG-encoded video information constitutes significant amount of transmitted data in broadband network. The paper investigates a gain which can be obtained when using results of statistical studies on stored MPEG files. Performance of transfer of MPEG information via CBR and rt-VBR links is studied.

The paper discusses the concept of spatial narratives based on so-called narrative links and their potential role within the implementation of flexible and thematic tourist information systems on mobile gps-enabled devices. References are made to two examples of specific application areas: one from a European city and one from an African urban region.

SUMMARY We present a set of Perl modules for the flexible and robust parsing and editing of EMBL/SWISS-PROT databases. AVAILABILITY The Web page at http://www.sanger.ac. uk/Software/PerlModule/ provides information about downloading the SPEM and PrEMBL modules, and provides links to documentation and example code.

Operational problems with robot manipulators in space relate to several factors, most importantly, structural flexibility and subsequent difficulties with their position control. In this paper we present control methods for endpoint tracking of a 12 6 12 6 m2 trajectory by a two-link robot manipulator. Initially, a manipulator with rigid links is modeled using inverse dynamics, a linear quadrat...

According  to  a  basic  prediction  made  by  the  Revised  Hierarchical  Model  (RHM),  at  early  stages  of language  acquisition,  strong  L2-L1  lexical  links  are  formed.  RHM  predicts  that  these  links  weaken with  increasing  proficiency,  although  they  do  not  disappear  even  at  higher  levels  of  language development. To test this prediction, two groups of highly proficie...

We describe a dialogue system that works with its interlocutor to identify objects. Our contributions include a concise, modular architecture with reversible processes of understanding and generation, an information-state model of reference, and flexible links between semantics and collaborative problem solving.

This paper presents development of a dynamic model of a two-link flexible manipulator. An explicit, complete, and accurate nonlinear dynamic model of the system is developed using assumed mode method. The Lagrangian approach is used to derive the dynamic model of the system. Several responses including angular positions and displacements of both links are obtained and analysed.

We present a methodology for automatically constructing structural hyperlinks for navigation and retrieval in large corpora. A structural hyperlink connects components of a document that have specified structural properties with word-based content similarity. Our approach enables queries that may be posed in terms of keywords, as well as structural segments such as definitions, figures, etc.

Visualization with a hierarchy of mathematical knowledge structure, assist learners in understanding mathematics. We are developing a method which constructs a hierarchy of mathematical knowledge by using hyperlink analysis in our mathematics e-learning site. Hierarchy is calculated by an adjacency matrix. 
