estimation of gold reserves and resources has been of interest to mining engineers and geologists for ages. the existence of outlier values shows the economic part of the deposits subject to the fact that don’t depend on the human or technical errors. the presence of these high values causes a pseudo dramatically increment in variance estimation of economical blocks when applying conventional m...

Face anti-spoofing (FAS) is a technology that protects face recognition systems from presentation attacks. The current challenge faced by FAS studies the difficulty in creating generalized light variation model. This because data are sensitive to domain. models using only red green blue (RGB) images suffer poor performance when training and test datasets have different variations. To overcome t...

Visible-light irradiation of phthalimide esters in the presence of the photosensitizer [Ru(bpy)3]2+ and the stoichiometric reducing agent benzyl nicotinamide results in the formation of alkyl radicals under mild conditions. This approach to radical generation has proven useful for the synthesis of small organic molecules. Herein, we demonstrate for the first time the visible-light photosensitiz...

We present a novel technique for particle sizing based on recent studies about the statistical information contained within the light intensity distribution close to a disordered sample. We show that it is much simpler and more robust than the traditional light scattering methods and any imaging technique. Applications to optical diagnostics, process monitoring and pollution monitoring are expe...

a common problem arising in project management is the fact that the baseline schedule is often disrupted during the project execution because of uncertain parameters. as a result, project managers are often unable to meet the deadline time of the milestones. robust project scheduling is an effective approach in case of uncertainty. upon adopting this approach, schedules are protected against po...
