Preliminary researches were carried out to study the effects of particle size on the wear behavior of a-C coating. The used nanoparticles are W (W-NPs), which have similar bulk hardness with ZrO2 (W: 7.5, ZrO2: 6.5, Mohs scale), but contain larger particles with the diameter of submicron and micron scale (Figure S1). The tribo-tests were performed under the same conditions with the ones used fo...

The purpose of this research is to quantify the potential of waste recycling in the form of participatory scenarios for separation from the source and to study the factors of minimization (reduction) of waste production in a district of Tehran. Amount of waste minimization was determined with considering a couple of citizens' participation scenarios. Source separation of valuable wastes includi...

SYSTEM R is a variant of the original STRIPS by Fikes and Nilsson (1971) (called forwardchaining, recursive STRIPS in Nilsson [1998]). Briefly speaking, given a conjunction of simple goals, it selects one of them to work on. If there is an action that is executable and will make this simple goal true once executed, then it does this action and then tries to achieve the other simple goals in the...

Colorectal cancer (CRC) is one of the leading cancers in the world and early-screening is still the best method of cancer patient survival. However, colonoscopy as the current gold standard is not without flaws and an emerging technique called surface-enhanced Raman spectroscopy (SERS) coupled with machine learning is a possible candidate that could be applied in parallel with colonoscopy. This...
