The Rio Cobre Irrigation Scheme, Jamaica, supplies water to 5000 ha by allocating a ®xed unit discharge at each offtake. A computer water management model, IRMOS, was used to assess the scheme's performance during a typical operating year and to identify water management constraints to performance. An optimal water allocation policy was used as a benchmark against which the actual performance w...

The excessive focus on water mounts a challenge to the sustainable development. Energy is another aspect that should be taken into account. Nexus approach is characterized by an equal emphasis on energy and water spheres. In arid areas, like the city of Kashan, Iran, non-conventional waters (e.g. desalinated and recycled waters) have been considered as an alternative resource of water. Nexus wa...

This article proposes a novel Pareto-based multiobjective meta-heuristic algorithm named non-dominated ranking genetic algorithm (NRGA) to solve multi-facility location-allocation problem. In NRGA, a fitness value representing rank is assigned to each individual of the population. Moreover, two features ranked based roulette wheel selection including select the fronts and choose solutions from ...

This paper investigates a cross layer scheduling scheme for OFDMA wireless system with heterogeneous delay requirements. Unlike most existing cross layer designs which take a decoupling approach, our design considers both queueing theory and information theory in modeling the system dynamics. The cross layer design is formulated as an optimization of total system throughput, subject to individu...

In this paper we developed a sub-optimal algorithm for joint routing and power allocation for an amplify-andforward multi-hop relay network. The objective function for the optimization is the received signal-to-noise ratio (SNR) at the destination. Higher SNR would cause for lower bit error rate consequently. The joint problem of power allocation and relay selection is formulated with respect t...

Optimal allocation of water resources is an effective way to solve the supply and demand contradiction between users. Recently, rapid economic social development Handan has significantly increased in various industries. Superimposed on reduction incoming upstream rivers limitation total amount groundwater extraction, a large number sources such as South-to-North Water Diversion, Yellow River We...

recently, the existing mechanism of the market has been considered as an efficient method for allocating water resources in some developed and developing countries. the necessary conditions to establish an efficient water market and its economic consequents must be recognized before using this method in iran. the purpose of this study is to investigate the economic consequences and present prac...
