Environmental management and planning problems cover important real life areas. These problems may include the scarcity of groundwater resource, the optimality of a multi-reservoir system, the management of forest resources, the air quality monitoring networks, the municipal solid waste policies, etc. Management and planning targets by authorities consist in allocations at appropriate places an...

Water resources systems management practice around the world is challenged by serious problems. Climate change and land use change are increasingly recognized as having the major impact on hydrologic variables and therefore on management of water resources. Certainly, the profession has been slow to acknowledge these changes, and that fundamentally new approaches will be required to address the...

introduction: when there is no determined value for water (as a public asset) by its trustees and beneficiaries and its allocation method is more dependent on the requirements of water consumers than comparing water affairs benefits with its real value, decision making on which interested group, when and to what extent can use water is a game. this study is aimed to determine sustainable polici...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

The Colorado River basin is facing a growing water shortage. Under fixed set of supply and demand conditions, we establish linear programming model based on time to solve the problem allocation. Take as objective function, get distribution coefficient α, β obtain from Hoover dam Glen Canyon dam. Finally it concluded that optimal function obtained when α 0.8 1.0. Dam 6947519530 m3 9309140232 m3.

In this paper, a guideline is provided for design and optimization of the shape of active transport molecular communication channels. In particular rectangular channels are considered and it is shown that for channels employing a single microtubule as the carrier of the information particles, the smaller the perimeter of the channel, the higher the channel capacity. Furthermore, it is shown tha...
