Damage to residual stand is unavoidable and it is one of the main important issues in the forest harvesting. Trees damage may occur in felling and skidding work phase or during skid trail construction. In any case, damage can be very serious to residual stand. Detailed study is necessary to find out the amount and severity of damage to trees; therefore district 14 of Kilesara in Guilan Province...

Hypersonic chemically reacting flow around a wedge in the near-continuum regime was numerically studied by the DSMC method with the main goal of validation of real gas effect models. The influence of vibration-dissociation coupling on the results of numerical simulations was analyzed. To this end, two models of chemical reactions were used in the computations, the total collisional energy model...

The interaction of laser-generated tandem microbubble (maximum diameter of about 50  μm) with single (rat mammary carcinoma) cells is investigated in a 25-μm liquid layer. Antiphase and coupled oscillation of the tandem microbubble leads to the formation of alternating, directional microjets (with max microstreaming velocity of 10  m/s) and vortices (max vorticity of 350 000  s{-1}) in opposite...

The computational fluid dynamics (CFD) analysis is the latest technology, and also accuracy very close to experimental analysis. In present work, effect of shape size feedstock powder particles analyzed upon impact velocity cold spray (CS) coating via CFD geometry for work has been drawn by SolidWorks, carried out through fluent. with best input parameters CS coating. pressure-based; axisymmetr...

The Smart Class Room concept requires modern technology to control and monitor Liquid Crystal Display Projector devices. This can be created by implementing the Internet of Things. LCD controlled remotely via an android-based mobile application. Research Development is right method produce prototypes. results implementation system show that remote internet using a realtime firebase database ach...
