Multiresolution information measures applied to speech recognition
Torres, María E.; Rufiner, Hugo L.; Milone, Diego H.; … - In: Physica A: Statistical Mechanics and its Applications 385 (2007) 1, pp. 319-332
Considerable advances in automatic speech recognition have been made in the last decades, thanks specially to the use of hidden Markov models. In the field of speech signal analysis, different techniques have been developed. However, deterioration in the performance of the speech recognizers has...

Impact of network structure on the capacity of wireless multihop ad hoc communication
Krause, Wolfram; Glauche, Ingmar; Sollacher, Rudolf; … - In: Physica A: Statistical Mechanics and its Applications 338 (2004) 3, pp. 633-658
As a representative of a complex technological system, the so-called wireless multihop ad hoc communication networks are discussed. They represent an infrastructure-less generalization of todays wireless cellular phone networks. Lacking a central control authority, the ad hoc nodes have to...

Distributive routing and congestion control in wireless multihop ad hoc communication networks
Glauche, Ingmar; Krause, Wolfram; Sollacher, Rudolf; … - In: Physica A: Statistical Mechanics and its Applications 341 (2004) C, pp. 677-701
Due to their inherent complexity, engineered wireless multihop ad hoc communication networks represent a technological challenge. Having no mastering infrastructure the nodes have to selforganize themselves in such a way that for example network connectivity, good data traffic performance and...

Continuum percolation of wireless ad hoc communication networks
Glauche, Ingmar; Krause, Wolfram; Sollacher, Rudolf; … - In: Physica A: Statistical Mechanics and its Applications 325 (2003) 3, pp. 577-600
Wireless multi-hop ad hoc communication networks represent an infrastructure-less and self-organized generalization of todays wireless cellular networks. Connectivity within such a network is an important issue. Continuum percolation and technology-driven mutations thereof allow to address this...

Complex networks: Effect of subtle changes in nature of randomness
Goswami, Sanchari; Biswas, Soham; Sen, Parongama - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 5, pp. 972-979
In two different classes of network models, namely, the Watts Strogatz type and the Euclidean type, subtle changes have been introduced in the randomness. In the Watts Strogatz type network, rewiring has been done in different ways and although the qualitative results remain the same, finite...

Dynamics of cluster structures in a financial market network
Kocheturov, Anton; Batsyn, Mikhail; Pardalos, Panos M. - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 523-533
In the course of recent fifteen years the network analysis has become a powerful tool for studying financial markets. In this work we analyze stock markets of the USA and Sweden. We study cluster structures of a market network constructed from a correlation matrix of returns of the stocks traded...
