Design strategies to enhance modern irrigation practices, reduce energy consumption, and improve water use efficiency crop yields are fundamental for sustainability. Concerning Center-Pivot Irrigation Systems, different design procedures aimed at optimizing have been proposed. Recently, following a gradually decreasing sprinkler spacing along the pivot lateral with constant diameter flow rate, ...

to evaluate symbiotic effectiveness and salt tolerance of sinorhizobium meliloti strains, 50 rhizobial strains were isolated from root nodules of medicago sativa cultivated in tehran and zanjan fields. under n-free conditions, the symbiotic effectiveness of different sinorhizobium meliloti strains of bami cultivar were evaluated under greenhouse conditions using 50 sinorhizobium meliloti strain...

Abstract. In the manufacturing process, designed part will be presented in a drawing with all dimensions normally given within certain range of tolerances. The tolerance defines limits induced deviation for which allowance should made design, and actual size is acceptable. laser abrasive water jet cutting, dimensional accuracy one important parameters to define quality produced part. aim presen...

This paper presents two recent hierarchical interconnection networks, the Block Shift Network (BSN) and the Hierarchical Cubic Network (HCN). Then a comparison between them has been done in terms of reliability and fault tolerance issues such as the fault diameter and the 2-terminal reliability. The comparison between them is depending on different factors such as the topological properties and...

Abstract In the strength design of sleeve joint structure, manufacturing tolerance and fit clearance are generally ignored. The load connecting screw is usually calculated by method linear distribution. contact force between cabin simulated deterministic finite element method. command flow probability analysis for typical circular section socket structure developed based on APDL. uncertainty de...
