Arleigh Burke Class DDG 108 Named for Wayne Meyer, a former ATI instructor.
An Arleigh Burke Class DDG 108 was named for Wayne Meyer, a former ATI instructor. Rear Adm. Wayne E. Meyer is also known as the father of AEGIS. After he retired from the Navy in 1985 he taught several professional development classes on Combat Systems Engineering for ATI based on his many years of systems engineering experience with the AEGIS combat System. Wayne E. Meyer passed away on Sept 1, 2009, and did not get to see this ship's commissioning, which bears his name, but his legend as 'father of Aegis" is well known. Click here to read more
Special Acoustics Resources
CJS Labs - a consulting firm based in San Francisco, California. CJS specializes in audio and electroacoustics applications. With over 25 years of industry experience in engineering and technology management, areas of expertise include transducers, acoustics, system design, instrumentation, measurement and analysis techniques, hearing science, telephonometry, speech intelligibility, and perceptual coding.
The Ocean Acoustics library contains acoustic modeling software and data. It has useful links to acoustic modeling software.
Dr. Kay is author and presenter of Practical Statistical Signal Processing - using MATLAB, a 4-day course covers signal processing systems for radar, sonar, communications, speech, imaging and other applications based on state-of-the-art computer algorithms. Like all ATI courses it can be presented at a place and time of your choosing for six or more qualified students.
The Efficacy of Submarine Warships, by Capt. Ray Wellborn. -- Capt. Wellborn is author and presenter of Submarines and Their Combat Systems, a three-day course examining the design, construction and deployment of submarines. Like all ATI courses it can be presented at a place and time of your choosing for six or more qualified students.

Navy University Laboratories
Since World War II, the Navy has maintained a substantial and continuing relationship with several university research laboratories, of which five remain today:
- The Applied Physics Laboratory at The Johns Hopkins University (JHU/APL)
- The Applied Physics Laboratory at The University of Washington (APL/UW)
- The Applied Research Laboratory at The Pennsylvania State University (ARL/PSU)
- The Applied Research Laboratories at The University of Texas at Austin (ARL/UT)

Acoustic Handbook and Training Reference Guide
The Environmental Acoustical Handbook provides useful reference information for Underwater Acoustics. The handbook was published under government contract in 1991 by Planning Systems Incorporated. The information is still useful today. ATIcourses republishes this information to provide useful information to the acoustics and sonar community.
- Fundamental Units
International System of Units
The International System of Units (SI) established in 1960 by the General Conference of Weights and Measures under the Treaty of the Meter is based upon: the meter (in) for length; the kilogram (kg) for mass; the second (s) for time; the Kelvin (K) for temperature; the ampere (A) for electrical current; and the candela (ed) for luminous intensity.
AU other units of SI are derived from these base units by assigning the value unity to the proportionality constants in the defining equations, e.g.,
I Pa = I N/m2 = (I kg - in / seC2) / M2 = I kg - M-1 . sec-2.
Taking 1/100 of the meter as the unit for length and 1/1000 of the kilogram as the unit for mass gives rise similarly to the cgs system, often used in physics and chemistry.
