Proceedings of the 7^th World Congress
on Electrical Engineering and Computer Systems and Science (EECSS'21)

On behalf of the International Academy of Science, Engineering and Technology (International ASET Inc.), the organizing committee would like to welcome you to the 7^th World Congress on Electrical Engineering and Computer Systems and Science (EECSS'21).

Due to the evolving COVID-19 outbreak and corresponding issues in border entry in European countries, the 7^th World Congress on Electrical Engineering and Computer Systems and Science (EECSS'21) which was supposed to be held in Prague, Czech Republic will be held virtually instead on July 29 – 30, 2021.

EECSS is aimed to become one of the leading international annual congresses in the fields of electrical engineering and computer systems and science. This congress will provide excellent opportunities to the scientists, researchers, industrial engineers, and university students to present their research achievements and to develop new collaborations and partnerships with experts in the field.

While each conference consists of an individual and separate theme, the 5 conferences share considerable overlap, which prompted the organization of this congress. The goal of this undertaking is to bring together experts in each of the specialized fields, and at the same time allow for cross pollinations and sharing of ideas from the other closely related research areas.

We thank you for your participation and contribution to the 7^th World Congress on Electrical Engineering and Computer Systems and Science (EECSS'21). We wish you a very successful and enjoyable experience.
