Fine grain products are harvested in two manual and mechanized forms. Nowadays, common combine harvesters are used, but fine grain products such as Rapeseed, Sesame and Sorghum cannot be harvested with conventional heads of combine harvesters due to the excessive grain loss in the head of the combine. Therefore, the necessity of design and fabricating machines and heads of combine harvesters be...

The grain size refinement of AISI 422 martensitic stainless steel in the temperature range of 950-1150 ºC was investigated by hot deformation tests. The deformed specimens were held at deformation temperature with delay times of 5 to 300s after achieving a strain of 0.3. The austenite grains exhibit a considerable growth at temperature higher than 1050˚C, while the grain coarsening is negligibl...

A coarse-grain parallel program typically has one thread (task) per processor, whereas a fine-grain program has one thread for each independent unit of work. Although there are several advantages to fine-grain parallelism, conventional wisdom is that coarse-grain parallelism is more efficient. This paper illustrates the advantages of fine-grain parallelism and presents an efficient implementati...

the pull- out strength of the reinforcement has a significant role on the function of the most reinforced soil structures. since the coarse grain soils have a better interaction with the reinforcement, they are mostly used in these structures. in most situations, we have to transfer these granular soils from the borrow area, usually far from the site of the project. this will impose a considera...

Fine-grain and coarse-grain computing architectures are evaluated with regard to a hardware implementation with optoelectronic interconnects. Three examples for fine-grain optoelectronic VLSI architectures are presented and their hardware requirements are specified. Furthermore technological aspects of a realisation of an optical interface with high density for fine-grain optoelectronic VLSI ar...

Within the parallel genetic algorithm framework, there currently exists a growing dichotomy between coarse-pain and fine-grain parallel architectures. This paper attempts to characterize the need for fine-grain parallelism. and to introduce and compare three models of fine-grain parallel genetic algorithms (GAS). The performance of the three models is examined on seventeen test problems and is ...

a nano/ultra-fine grain al-0.2wt% zr alloy was produced by accumulated roll bonding (arb) processafter 10 cycles. the fraction of high angle grain boundaries increased from 8% to 65.4% during 10passes during arb process. this alloy was subjected to tensile test at different temperatures (523,573and 623 k) and strain rates (0.1 and 0.01 s-1). the optimum condition of temperature and strain rate ...

Sparse matrix problems require a communication paradigm different from those used in conventional distributed-memory multiprocessors. We present in this paper how fine-grain communication can help obtain high performance in the experimental distributed-memory multiprocessor, EM-X, developed at ETL, which can handle fine-grain communication very efficiently. The sparse matrix kernel, Conjugate G...

Computer hardware is at the beginning of the multi-core revolution. While hardware at the commodity level is capable of running concurrent software, most software does not take advantage of this fact because parallel software development is difficult. This project addressed potential remedies to these difficulties by investigating graphical programming and fine-grain parallelism. A prototype sy...
