Community detection in inflectional networks

Inflection classes partition the lexicon, classifying lexemes into groups based on shared inflectional exponence; as such, they are foundational aspects of lexical organisation. The task of identifying good partitions is non-trivial, however. We show that a modularity-based community detection method, borrowed from network theory, allows for identification of intuitive partitions at different granularities of representation. Applied to French verbs and Bosnian/Croatian/Montenegrin/Serbian nouns, the method detects inflection classes at multiple granularities and reveals (imperfect) hierarchical organisation of these. Ultimately, community detection methods facilitate more nuanced understanding of the inflectional organisation of the lexicon. Keywords: lexicon; morphology; inflection classes; hierarchical organisation; network science; community detectio

CHALLENGES AND OPPORTUNITIES FOR THE SLOVENIAN ELECTRICITY MARKET

Slovenija je nakon osamostaljenja prilikom priprema za uključenje u Europsku uniju krenula na put institucionalnog i organizacijskog preoblikovanja elektroenergetskog sektora sukladno europskim smjernicama i direktivama. Pri tome je morala pratiti osnovni cilj, to jest, kako s uvođenjem tržišnih odnosa unutar elektroprivrednih djelatnosti i između elektroprivrede i potrošača postići konkurentne cijene električne energije i na taj način sniziti troškove te povećati dodanu vrijednost i konkurentnost gospodarstva. Poslovni rezultati elektroenergetskog sektora ukazuju na uspješnost restrukturiranja. Slovenska se elektroprivreda ubrzano priprema na nove izazove elektroenergetskog sektora – prije svega potpuno otvaranje tržišta i tržišno dodjeljivanje prekograničnih prijenosnih kapaciteta, nakon 1. srpnja 2007. godineFollowing independence and during the period of preparation for entry into the European Union, Slovenia embarked upon the institutional and organizational reconstruction of the electricity sector, pursuant to European guidelines and directives. The basic goals were to achieve competitive electricity prices, and so reduce costs and increase the added value and competitiveness of the economy through the introduction of market relations within the operations of the electric power industry and between the electric power industry and electricity consumers. The performance of the electricity sector is an indication of the success of this reconstruction. The Slovenian electric power industry has accelerated preparations for the new challenges confronting the electricity sector - first of all the complete opening of the market and the market allocation of cross-border transmission capacities after July 1, 2007

Experimental validation of a hypothesis for lung tumour dynamic characterisation *

This paper describes seminal work for using tools from fractional calculus on modelling geometry and dynamical nonlinear effects in a mimicked lung tumour setup. A device and methodology are tailored to verify the hypothesis that presence of tumour in lung will affect the frequency dependent respiratory impedance. The data is analysed in terms of detection and quantification of nonlinear distortion in two situations mimicked by the proposed setup: a normal lung and a tumorous lung. Results indicate the feasibility of this research direction and the paper outlines the opportunities at hand
