A large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the transverse direction at each cross-section as well as in the longitudinal direction along the river channel. This study presents three algorithms to resample the river cross-section data points in both the transverse and longi...

OBJECTIVES To examine nonylphenol (NP) and 4-t-octylphenol (OP) concentrations and general water quality indicators along a river in the greater Tokyo area and to specify the distribution and origin of alkylphenols. METHODS Water was sampled from the Edogawa River, a main river in the greater Tokyo area, which is a source of public drinking water; and the Sakagawa River system, a tributary of...

Karun River is the largest and most watery river in Iran. This river is the longest river which located just inside Iran and Ahvaz Metropolis drinking water supplied from Karun River as well (fa.alalam.ir). Karun River as the main source of water treatment plants in Ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

RÉSUMÉ. L’indexation sémantique de documents à partir d’ontologies est un domaine qui prend de l’essor, malgré les difficultés d’une indexation automatique ou même semi-automatique, sans parler d’indexation manuelle. Il est possible désormais d’avoir des caractérisations sémantiques de documents textuels ou non textuels basées sur des ontologies. Partant de ce fait, nous avons mis en place un o...

RÉSUMÉ.Dans cet article, nous étudions les jeux d’accessibilité généralisée : ce sont des jeux à deux joueurs à somme nulle, pour lesquels l’objectif du premier joueur, Ève, est donné par une conjonction d’objectifs d’accessibilité. Dans un premier temps, nous montrons que le problème de décider si Ève a une stratégie gagnante est PSPACE-complet, mais polynomial en fixant pour paramètre le nomb...

Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...
