Distributed multi-agent optimization finds many applications in distributed learning, control, estimation, etc. Most existing algorithms assume knowledge of first-order information the objective and have been analyzed for convex problems. However, there are situations where is nonconvex, one can only evaluate function values at finitely points. In this paper we consider derivative-free nonconve...

in this research, graphene oxide- gold nanoparticles (aunp/go) were easily fabricated by a redox reaction between go and chloroauric acid without using any additional reductant and then used to stabilize pickering emulsions. (aunp/go) was investigated by ft-ir spectroscopy. the changes of parameters such as contact time, ph, amoxicillin initial concentration and temperature were tested and inve...

Removal of fluoride ions was investigated using a new adsorbent of yttrium alginate biocomposite (YALG). Effect of various parameters such as pH, contact time, initial concentration of fluoride ions and temperature on the sorption capacity of adsorbent was studied. Performing a mathematical assessment of fluoride sorption, isotherm and kinetics models including Freundlich & Langmuir isotherms a...

The release of metformin, a drug used in the treatment cancer and diabetes, from poly(2-hydroxyethyl methacrylate), pHEMA, hydrogel-based microneedle patches is demonstrated vitro. Tuning composition pHEMA hydrogels enables preparation robust with mechanical properties such that they would penetrate skin (insertion force single to be ≈40 N). Swelling experiments conducted at 20, 35, 60 °C show ...

The aim of the study is to construct a mathematical model kinetics multiple ethanol intake based on kinetic equation zero-order elimination with absorption and irrevocable first-order deficiency, as well its implementation in format computer program. Analytical modeling oral administration performed basis this equation. In course modeling, summation method was developed that allows perform desc...
