results the simulation results showed that the penetration depth and temperature rise of 980 nm wavelengths were different from those of 1064 nm wavelength. it appeared that 1064 nm wavelength penetrated to deeper layers of tissue compared with 980 nm. moreover, temperature rise during 1064 nm irradiation led to temperature increase in allowable ranges. the findings proved the reason why 1064 n...

One of the most valid and efficient models of long rod projectile penetration in homogeneous targets is Tate and Alekseevskii’s (A&t) model. Based on Tate’s model, the present research tries to calculate the optimum speeds to achieve the maximum penetration depth in the homogeneous targets. The proposed collision speed-penetration depth diagrams are developed using Tate’s model. In this way, va...

Penalty approaches can be used to efficiently resolve collisions of dynamically simulated rigid and deformable objects. These approaches compute penalty forces based on the penetration depth of intersecting objects and there exist many algorithms for estimating the exact penetration depth. However, in discrete-time simulations, this information can cause non-plausible collision responses in cas...

We present a new measure for computing continuous penetration depth between two intersecting rigid objects. We generate a set of samples in the configuration space, precompute an approximation of the contact space for two intersecting objects using binary classification techniques, and construct a bijective mapping between the spherical space and the precomputed contact space. For a given in-co...

In this experimental work, Manganese oxide (MnO2), Zinc oxide (ZnO), Iron oxide (Fe2O3) and Magnesium chloride (MgCl2) were used as activating flux to investigate the effects for SS 304 in tungsten inert gas (TIG) welding. Ultimate tensile strength, percentage elongation, Penetration depth and width were studied of material SS 304. The experimental results indicated that the MnO2 and Fe2O3 flux...

introduction: the penetration depth of irrigating solutions in dentinal tubules is limited; consequently, bacteria can remain inside dentinal tubules after the cleaning and shaping of the root canal system. therefore, new irrigation systems are required to increase the penetration depth of irrigating solutions in dentinal tubules. methods: a comparative study regarding the penetration depth of ...

The development of spray is one of the important factors effecting the combustion of PFI engines. This research was carried out in order to investigate some of the spray characteristics from PFI injector. In this study, the injector flux was investigated by a mass method and equations for it were presented. The results showed that in the pressure interval (2 to 6 bar), the relation of flux with...
