the implementation of different silvicultural systems can be effective on different characteristics of forest stands, such as stand structure and diameter distribution of trees. this study was carried out in shafaroud forests of gilan province of northern iran. the objectives of this research were 1) to evaluate the suitability of different probability distribution functions, including weibull,...
Physics-based process simulations have the potential to allow virtual design and development of digital twins for smart machining applications. This paper presents 3D cutting using finite element method (FEM) investigates physical state variables that are fundamental reduction in forces, friction, tool wear when micro-textured tools employed. For this goal, textured cemented carbide inserts des...
Influence of cutting edge micro-geometry in micro-milling of copper alloys with reduced lead content
Miniaturization encourages the development of new manufacturing processes capable of fabricating features, like micro-channels, in order to use them for different applications, such as in fuel cells, heat exchangers, microfluidic devices and micro-electromechanical systems (MEMS). Many studies have been conducted on heat and fluid transfer in micro-channels, and they appeared significantly devi...
X-ray microfocus computed tomography (micro-CT) is recently put forward to qualitatively and quantitatively characterize the internal structure of porous materials. However, it is known that artifacts such as the partial volume effect are inherently present in micro-CT images, thus resulting in a visualization error with respect to reality. This study proposes a validation protocol that in the ...
Single-node leafy stem cuttings of Shorea leprosula Miq. were subjected to a high, intermediate or low irradiance treatment for 16 weeks in an enclosed mist propagation system. Before rooting, maximum photosynthesis of the cuttings occurred at an irradiance of 400 micro mol m(-2) s(-1). Although none of the irradiance treatments affected the number of roots produced per cutting, the numbers of ...
• A weak magnetic field can enhance ductile-mode cutting of CaF 2 single crystal. Magnetic direction shows anisotropy in affecting ductile–brittle transition. coupled analysis magneto-plasticity and crystal plasticity is developed. Dislocation behaviour fracture toughness are revealed under field. DFT computation corroborates the magnetic-induced dislocation depinning theory. Magneto-plasticity...
