Query: Fault Detection using Immune-Based Systems and Formal Language
  Algorithms   This paper describes two approaches for fault detection: an immune-based
mechanism and a formal language algorithm. The first one is based on the
feature of immune systems in distinguish any foreign cell from the body own
cell. The formal language approach assumes the system as a linguistic source
capable of generating a certain language, characterised by a grammar. Each
algorithm has particular characteristics, which are analysed in the paper,
namely in what cases they can be used with advantage. To test their
practicality, both approaches were applied on the problem of fault detection in
an induction motor.
