• Joseph Sauveur (1653–1716) coined the word “acoustics” for the science of sound. • Sir Isaac Newton (1642–1727) his law of motion is routinely used to derive the equations of motion of a vibrating body. • Brook Taylor (1685–1731), obtained the natural frequency of vibration observed by Galilei and Mersenne.

OVERVIEW OF HEURISTIC OPTIMIZATION

web.eng.fiu.edu

OPTIMIZATION (Eberhart Kennedy -1995) A robust stochastic optimization technique inspired by the social behavior of swarms of insects or flocks of birds –maximize “food”. Apply the concept of social interaction to problem solving. Developed in 1995 by James Kennedy (social-psychologist) and Russell Eberhart (electrical engineer).

Because sound travels effectively in the same or opposite direction of airflow, downstream and upstream paths are often equally important. This chapter provides basic sound and vibration principles and data needed by HVAC system designers. Many of the equations associated with sound and vibration control for HVAC may be found in Chapter 8 of the

A sound wave is a longitudinal wave, which alternately pushes and pulls the material through which it propagates. The amplitude disturbance is thus parallel to the direction of propagation. Sound waves can propagate through the air, water, Earth, wood, metal rods, stretched strings, and any other physical substance.
