The agricultural sector is of particular importance in the city of Bijar. Thus, the economic value perunit of water applid to the side effects of excessive groundwater resources in this area has a utmostimportance. Payment for estimation of water on a suitable production function was estimated revenueproducers. Therefore in this study to estimate the economic value of water resources in agricul...

We present a novel approach to wireless fair scheduling in a distributed architecture. Our scheme is based on a simple extension of wireline fair scheduling by compensation for lost capacity after the losses occur. In addition, the scheduler can give limited compensation for unused capacity. This provides an incentive for users of the location-dependent wireless channel to optimize their channe...

“Egypt is a gift of the Nile,” wrote Herodotus, and indeed, without the Nile there would be no Egypt as the world knows it. Egypt is mainly dependent on the flow in the Nile River (with an agreed share of 55.5 BCM) and it receives about 1.3 BCM rainfall annually (mainly along the north coast). The overall water use efficiency is already high, due to e.g., water scarcity and reuse of drainage wa...

Abstract Query execution techniques in database systems constantly adapt to novel hardware features achieve high query performance, particular for analytical queries. In recent years, vectorization based on the Single Instruction Multiple Data parallel paradigm has been established as a state-of-the-art approach increase single-query performance. However, since concurrent queries running often ...

Infiltration and inflow water (I/I-water) is a big challenge in sewage systems many countries. I/I-water above an acceptable level indicates that the system not functioning properly. leads to increased pumping costs overflow, leading pollution of receiving waters. Many rehabilitation projects are driven by need reduce share common measures replace pipes manholes. The predominantly rainfall. Thi...
