due to increasing demand for the scarce available water throughout the world it is an extremely important matter, in water management, to make serious attempts in determining its true economic value. this paper discusses the optimal allocation of water to agriculture, the relatively true economic value of water as well as the cropping patterns for the shirvan barzo (sb) dam area in north kh...

The problem of efficient resource allocation has drawn significant attention in many scientific disciplines due to its direct societal benefits, such as energy savings. Traditional approaches in addressing online resource allocation problems neglect the potential benefit of feedback information available from the running tasks/loads as well as the potential flexibility of a task to adjust its o...

this study was conducted to determine the effect of variable nitrogen supply on yield parameters of two sugar beet varieties, as well as on biomass allocation to different parts of sugar beet plant at safi-abad agric. res. center during 2003-4 and 2004-5. five nitrogen rates (0, 60, 120, 180 and 240 kgha-1) and two monogerm sugar beet varieties (shirin and rasol) arranged as factorial in a rand...

This paper presents a novel architecture called the MetaGrid based on Grid computing concepts for resource provisioning for wide-area network-enabled applications. Resource provisioning for wide-area applications can involve coordinated allocation of computing and communication resources. A Grid computing systems provides a virtual framework that facilitates controlled resource sharing among di...

This paper presents Multi-Amdahl, a resource allocation analytical tool for heterogeneous systems. Our model includes multiple program execution segments, where each one is accelerated by a specific hardware unit. The acceleration speedup of the specific hardware unit is a function of a limited resource, such as the unit area, power, or energy. Using the Lagrange theorem we discover the optimal...

Choosing appropriate fragment allocation in Distributed Database Systems is an important issue in design of Distributed Database Management System .Several fragmentallocation algorithms have been suggested in the area of DDBMS design. Each algorithm has its own strengths and shortcomings. Therefore, providing an appropriate algorithm is too critical in DDBMS design and may lead to an increase i...

This paper proposes a scratchpad memory allocation technique for stack data to achieve predictability for hard real-time embedded systems. First, we suggest a profiling-based source code modification technique to make the whole stack area fit in the given scratchpad memory size. Furthermore, even though the whole stack area cannot fit in the scratchpad memory size, we propose another scratchpad...

This paper deals with the design of processor arrays for algorithms which can be represented as systems of uniform recurrence equations. We present an approach to determine allocation functions as part of this design. The objective of our approach is to generate allocation functions minimizing the necessary chip area for a hardware implementation of a processor array. At first, we propose an al...
