The method of solution evaluation

The present study focuses on the preparation of silver/copper bimetallic hybrid nanoparticles by green method from precursor solutions of silver nitrate & copper nitrate and the locally available citrus fruit (lemon) peel extract which behaves as the stabilizing and reducing agent. Initially, the formation of hybrid nanoparticles was noticed in the reaction mixture by colour change.

The study "Studies on film forming corrosion inhibitors on aluminium alloy, AA2024-T3" presents key aspects of the film forming behaviour of the selected inhibitors and the test methods used to evaluate the inhibitor induced films in a chloride solution. This study also aims to provide significant insights to the film tenacity, the influence of the molecular structure as well as the film stability in the absence of inhibitors to provide a deeper understanding of the film forming and film breakdown mechanisms.

In the work "Master's thesis of Science: User delay tolerance - aware edge node placement optimization for cost minimization", we review the related works and identify the research gaps in Chapter 2. Then, we formulate our problem in Chapter 3 and prove the NP-hardness of the problem in Chapter 4. Base on our problem formulation, we provide a suit of solutions in Chapter 5. After that, we do an comprehensive evaluation on our proposed methods in Chapter 6. Finally, we summarise our work in Chapter 7.

Propose the global – local mean square error criterion (GLOMSEC) for Gaussian equivalent linearization method (GEL) for randomly excited MDOF nonlinear system subjected to white noise or color noise excitation. The mean square of response solution will be concentrated to evaluate the accuracy of the proposed criterion by comparison with exact solution or other accepted solutions.

In this paper we study linear stochastic implicit difference equations (LSIDEs for short) of index-1. We give a definition of solution and introduce an index-1 concept for these equations. The mean square stability of LSIDEs is studied by using the method of solution evaluation. An example is given to illustrate the obtained results.

A simple and inexpensive method was developed using liquid - liquid extraction, together with high performance chromatographic method for determination of methoxyfenozide residues in grapes. The evaluated parameters include the extracts by distilled water and acetonitrile solvents. The method was validated using grapes samples spiked with methoxyfenozide at different fortification levels (0.05, 0.1 and 0.5 µg/g). Average recoveries (using each concentration three replicates) ranged 86-95 %, with relative standard deviations less than 5%, calibration solutions concentration in the range 0.

Inhibition ability of mild steel corrosion of 4 amides (RCONH2 (marked as A4), RCONH– CH2–CH2OH (marked as A5), RCON(CH2–CH2OH)2 (marked as 6b) and RCONH–(CH2)2–NH– COR (marked as 7c) prepared as derivatives from aliphatic acid oxidatively synthesized from nparaffin of Vietnam crude oil, has been examined by electrochemical methods. The corrosion test has been performed in chloride 3% solution at room temperature. The inhibition efficiency has been evaluated through corrosion potential Ecor, corrosion current icor and some other corrosion parameters.
