La Teoría de Grafos aplicada al estudio del consumo sectorial de agua en Andalucía.

Alonso, Esther Velázquez - Centro de Estudios Andaluces, Government of Andalusia - 2003

of the economy itself. A mixed methodology has been used, combining Input-Output analysis with Graphs Theory. We obtain a … water Input-Output model and an interrelationship matrix which is analysed by Graphs Theory. The main conclusion is that …

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...

Efektywne obliczanie zapasow wszystkich czynnosci w sieci szeregowo-rownoleglejz przedzialowymi czasami wykonania czynnosci

Zielinski P. - In: Operations Research and Decisions 4 (2003)

W artykule rozwaza sie problem obliczania przedzialow mozliwych wartosci zapasow (calkowitych zapasow) czynnosci w sieciach, w ktorych czasy wykonania czynnosci sa zadane nieprecyzyjnie za pomoca liczb przedzialowych. Rozwazany problem jest silnie NP-trudny w klasie dowolnych sieci i pozostaje...

Measurement distortion of graphs in corporate reports: an experimental study

Beattie, Vivien; Jones, Michael John - In: Accounting, Auditing & Accountability Journal 15 (2002) 4, pp. 546-564

Graphs in corporate annual reports are a double‐edged sword. While they offer the potential for improved communication … of accounting information to users, the preparers of the annual reports can easily manipulate the graphs for their own … financial performance. This study uses an experimental approach to address this issue. Pairs of graphs are shown to establish …

Structural Transformations and Important Coefficients in the North American Economies

Aroche-Reyes, Fidel - In: Economic Systems Research 14 (2002) 3, pp. 257-273

This paper assesses a few issues related to the question of finding the so-called important coefficients in an input-output table. Further, these coefficients are located in the corresponding matrices of Canada, the USA and Mexico. Important coefficients are analysed employing graph theoretical...

Temporal fractal structures: origin of power laws in the world-wide Web

Tadić, Bosiljka - In: Physica A: Statistical Mechanics and its Applications 314 (2002) 1, pp. 278-283

Using numerical simulations and scaling theory we study the dynamics of the world-wide Web from the growth rules recently proposed in Tadić (Physica A 293 (2001) 273) with appropriate parameters. We demonstrate that the emergence of power-law behavior of the out- and in-degree distributions in...
