Applications of CyberPhysical Systems (CPS)
The CPS problem:
CPS has the end objective of orchestrating physical
processes. Timeliness, safety, reliability, security, privacy,
and adaptability all take on a different character.

Embedded software is software on small computers. The
technical problem is one of optimization (coping with
