ECE 595C - Biologically Inspired Engineering

Lecture Hours: 3 Credits: 3

Counts as:

Experimental Course Offered: Fall 2004

Catalog Description:
The objective of this course is to prepare the student to use modern design strategies rooted in biological principles. Examples include: the use of biological genetics as an inspiration for genetic algorithms for the automated design of components and systems; the use of linguistic based controls strategies based on human speech and logic to formulate control systems (a strategy formally known as fuzzy logic); the construction of artificial neural networks modeled after the construction of biological nervous systems for information processing and control; use of protein classification and identification algorithms to solve engineering design problems; and the study of immunology and how it relates to computer viruses and synthetic immune systems.

Course Objectives:
The development of complex, highly reliable integrated systems with greatly reduced design cycle times poses a formidable challenge to today's engineers. Traditional engineering design practices are not adequate to meet this new challenge; engineers are increasingly turning to biology for answers. Engineering has always borrowed from nature to provide conceptual examples (for instance, aerodynamics from birds). However, the extraordinary demands placed on today's engineering designs have resulted in the use of biological concepts in a concrete and mathematically defined way. These concepts include artificial networks that mimic the functioning of neurons in the brain, fuzzy logic that more closely reflects human reasoning, and genetic algorithms that imitate the mechanics of biological genetics. Future challenges facing engineering, science, and technology will require multidisciplinary education including proficiency in biologically inspired engineering. The objective of this course is to make students aware of biologically inspired engineering techniques and to equip them with multidisciplinary breadth - thus making them prepared to collaborate with their colleagues from other disciplines.
