Ductile compaction is common in many natural systems, but the temporal evolution of such systems is rarely studied. We observe surprising oscillations in the weight measured at the bottom of a self-compacting ensemble of ductile grains. The oscillations develop during the first ten hours of the experiment, and usually persist through the length of an experiment (one week). The weight oscillatio...
To evaluate the effects of tillage and planting systems on soil physical properties, grain yied and its components, and milling recovery of rice (cv. Hashemi), an experiment was conducted at Rice Research Institute of Iran in 2017 and 2018 cropping seasons-using split plot arrangements in randomized complete block design with three replications. The experimental factors were; tillage methods (m...
To use machine vision technology in visual quality control of cereal seeds, sufficient knowledge is necessary. In this work, the capability systems, equipped with industrial digital cameras for identification and classification seven-grain groups wheat seed samples, was studied. Two statistical models three support vector machines were employed study. Through image processing 21,000 single grai...
The effect of electron beam welding current changes on the microstructure and mechanical properties of the Nb-based alloy has been investigated. The electron beam welding was applied with 4 different currents of 20, 24, 30 and 35 mA on 3mm thick plates. The aspects including different welding regions, geometry and depth of welding penetration, as well as the effect of heat input on the weldabil...
