Round 1
Reviewer 1 Report
The writing of the paper needs a lot of improvement in terms of grammar, spelling, and presentations. The paper needs careful English polishing since there are many typos and poorly written sentences.
Some examples are as the following:
* Check the usage of the commas carefully.
* Check the articles including "a", "an" and "the".
* Check the required and unneeded blank spaces.
- the final part of the abstract is not attractive
-introduction you can present better novelty of your work
-literature analysis can be improved
-conclusions please report only relevant information
-please check all text to see grammatical errors
-Avoid repetitions. I can see several repetitions at different places in this paper. Thorough proofreading is required.
-There is no scope for future research. A clear direction for future research is required.
