Recent electronic devices are connected with each other by various connectivity techniques. This trend makes computing resources distributed over many devices. However, since the general DRM models assume contents and the corresponding rights should be stored in the same space or storage, they cannot fully support distributed environments. To fully utilize the distributed resource and to provid...

Zusammenfassung: Daten stellen die wichtigste Grundlage für Entscheidungen dar. Aber die meisten Unternehmen nutzen diese wertvollen Informationen nicht zur Entscheidungsfindung. Dabei liefert die Analyse, Verteilung und Anwendung von Wissen einen entscheidenden Wettbewerbsvorteil. Stetig anwachsende Berge unterschiedlichster Daten erschweren die Umwandlung in nutzbare, strukturierte Informatio...

As planning is applied to larger and richer domains the e ort involved in constructing domain descriptions increases and becomes a signi cant burden on the human application designer. If general planners are to be applied successfully to large and complex domains it is necessary to provide the domain designer with some assistance in building correctly encoded domains. One way of doing this is t...

road accident severity may be influenced by a number of various systematic causal factors. the weather and road accidents have a close relationship with each other and a number of methods have been proposed for measuring the risk of a road accident with rainy, foggy, and snowy weather and high winds. recent studies indicate that road collision rates increase during precipitation. the weather wa...

forests as a renewable source has effective and useful role in economic and social activities of society. network of forest roads as infrastructure division’s forest planning units (compartments) of forest management plans, management, logging, exit of wood and plays a major role forest protection. aim of this study, designed forest road network according to multi-purpose forestry using the net...

Forest road construction is the most costly operation in forestry. Road designing and construction in unsuitable areas may increase construction and maintenance costs and also cause many environmental impacts. Therefore, it is required to pay more attention to forest road design. In this research, we tried to introduce an appropriate method for locating forest roads using GIS and AHP simultaneo...

This study focused on the public transport risk assessment in District one of ​​Tehran through Fault Tree Analysis involving the three criteria of human, vehicle and road in Haddon matrix. In fact, it examined the factors contributing to the occurrence of road accidents at several urban black spots within District 1. Relying on road safety checklists and survey of experts, this study made an ef...

Forests are an important economic source for human and have key role in nutrient cycle, hydrology and ecosystem performance, any interference in this vital ecosystem causes to damage to forests. Mechanical logging and road construction in forest areas have led to much soil compaction. Soil physical and chemical properties were studied in parts of road and non-road in the Darabkola forest of Ira...
