About the talks:

Optimal wireless sensor network design

Prof. Dr Stefka Fidanova, Institute of Information and Communication Technologies, Bulgarian Academy of Science

A wireless sensor network (WSN) is formed by sensors which communicate wirelessly. Each sensor node monitories area around itself and transmits collected data to a central gateway (high energy communication node), which provides a connection to the wired world where they can be collected, processed, analysed, and presented. In this work we address a WSN layout problem instance in which full coverage is treated as a constraint, while objective functions are number of the sensors and energy efficiency.

Semantic Networks for Natural Language Processing

Dr Velislava Stoykova Institute of Bulgarian Language, Bulgarian Academy of Science

The presentation is focused on overview of different approaches to semantic networks for Natural Language Processing. The types of implementations and analysis of basic principles of related multilingual applications will be offered supported by generated example results for related and non-related languages. Finally, the conclusion about universal grammar knowledge presentation will be presented.      

Data mining of social networks to establish information flow

Dr Kristina Kapanova, Institute of Information and Communication Technologies, Bulgarian Academy of Science

The technological shifts in the past 40 years can be recognized as the primary conditions for the changes in the way people process information. The popularity of social media contributed to the emergence of new communication practices, information collection and activism. In this work we investigate the ecology of interactions in terms of a quantitative network analysis and categorisation of a user generated metadata from social networks and the behaviour of users in two distinct settings: as part of media fandom and as part of political association.

Signal processing application of a new polynomial derived Wavelet, based multiresolution analysis

Jomo Batola, School Media Arts and Technology, Southampton Solent University

The presentation intends to introduce how a new polynomial has been created and used to design a new filter bank based multiresolution analysis, from which a scaling and wavelet functions are derived. An application of such a wavelet for the detection and localisation of electric fault on power line is provided.
