Reviewer 1 Report
The research objective and hypothesis are not clearly defined. The authors present an extensive and interesting review of the literature, point out the advantages and disadvantages of the applied solutions, but I would expect them to specify exactly what their research refers to and what problems they want to solve. Why exactly their solution may be better? Which negative elements does it eliminate? This is what, in my opinion, is missing from the introduction.
The results are presented in a correct and interesting manner and the summary and discussion are appropriate. The conclusions are also complete. I would recommend to highlight the issues included therein also in the introduction.
