This dissertation examines a profit-maximizing project selection and scheduling problem. Assume that a set of potentially profitable projects are available, yet limited available resources may not allow all of them to be pursued. Profit profiles for projects are assumed to be non-increasing functions of project completion times, i.e. profit returns are sensitive to time-to-market. Decision need...
Catchment prioritization in terms of natural disaster intensity as well as prevention and control practices plays a main role in the natural resources and watershed management. In this study, a total of 24 sub-catchments in the Zohreh-Jarrahi basin were prioritized according to their morphometric parameters and using the mixed model of TOPSIS-Multivariate regression. A total of 12 morphometric ...
forest cover is one of the most effective factors in reducing flooding in northern iran, so that in recent years the destruction, land use changing and uncontrolled harvesting of forest areas, has greatly increased the number and magnitude of floods. so far, there have been few studies on forest hydrology in iran, particularly the northern hyrcanian forests. this study examines the impact of a ...
Soil erosion is one of the major environmental problems worldwide. Morphometric and landcover analysis provides a platform for quick and efficient watershed management In the present study, morphometric parameters have been coupled with land cover classes to assess soil erosion susceptibility of sub-watersheds of lavasanat watershed. The data used in this study included Advanced Space borne T...
Land preservation and restoration are important tools for managing imperiled aquatic species, but they are often applied in the absence of a transparent scheme of geographic prioritization. To help guide preservation and restoration efforts in the Conasauga River Basin in Georgia and Tennessee, we used the “Zonation” algorithm to prioritize sub-watersheds. Zonation is a prioritization system th...
introduction flood is a natural hazard that its occurrences can be observed more frequently in recent years. for better flood mitigation and control, it is needed to identify flood production factors and determine the high potential flood areas. hydrological model is a simplified representation of natural system and the rainfall-runoff model is one of the most frequently used events for flood s...
Prioritization of different regions at watersheds based on the erosion rate and sediment yield with approach of its economic effects can lead to the production of valuable information for projects of soil conservatism. The present study aim was sub-watersheds prioritization of Kan watershed based on erosion condition with the approach of economic losses from erosion and sediment. Therefore, the...
this research is a study on indicators of listening instruction in iranian english as a foreign language (efl) curriculum at guidance school and high school educational levels. this thesis aims at determining: a) the indicators of listening instruction at guidance school and high school efl curriculum. b) the indicators of listening instruction in irans guidance school and high school efl curri...
Currently, there are a lot of e-learning and collaborative platforms to support distance and collaborative learning, however, all of them were designed just like an application without considering the network infrastructure below. Under these circumstances when the platform is installed and runs in a campus, sometimes it has very poor performance. This paper presents a network and data link lay...
Soil erosion has been one of the most important problems of watersheds in the world and is considered one of the main obstacles to achieving sustainable development in agriculture and natural resources. Identifying and prioritizing regions sensitive to soil erosion is essential for water and soil conservation and natural resource management in watersheds. The present research was performed in 2...
