1. Introduction
Symmetry is a frequent pattern widely studied in different research fields. In particular, complex systems with symmetry arise in engineering science (e.g., in mechanical engineering, symmetric and synchronized systems are often used to satisfy stability criteria for rotating structures; in electrical engineering, the study of symmetrical and asymmetrical faults in power systems is a critical issue; in telecommunications engineering, many systems are symmetrical since data speed or quantity is the same in both directions; in civil engineering, the strength of the objects depend on the symmetry; in computer engineering, symmetric network structures and symmetric algorithms are often studied, etc.).
This Special Issue invites researchers to submit original research papers and review articles related to any engineering discipline where theoretical or practical issues of symmetry are considered. The topics of interest include, but are not limited to:
Symmetry in electrical and electronic engineering
Symmetry in mechanical engineering
Symmetry in automation and robotic engineering
Symmetry in computer engineering
Symmetry in telecommunications engineering
Symmetry in civil engineering (transportation, hydraulics, etc.)
Symmetry in chemical engineering
Symmetry and topology of complex networks in engineering
Symmetry and optimization in engineering applications
