The 10 GREATEST FILIPINO ENGINEERS
1. DR. LEON CHUA
A professor of electrical engineering and computer science at the University of California at Berkeley, Dr. Leon O. Chua is widely recognized as the father of nonlinear circuit theory and cellular neural networks (CNN). The CNN architecture is the only one implemented into a practical fully-programmable chip for solving ultra-high-speed pattern recognition and image processing problems. The CNN universal machine chip is capable of a thousand times greater performance in speed, weight and power consumption than related technologies. Dr. Chua also invented a five-element circuit for generating chaotic signals. Aptly named the Chua Circuit, it is used by many researchers to design secure communications systems based on chaos.
An IEEE Fellow, he is a past president of the IEEE Circuits and Systems Society and former editor of the IEEE Transactions on Circuits and Systems.
Dr. Leon Chua, (BSEE)- Former Dept Chair, University of California, Berkeley, Electrical Engineering. First recipient of the 2005 Gustav Kirchhoff Award---the highest IEEE Technical Field Award for outstanding contributions to the fundamentals of any aspect of electronic circuits and systems; recipient of the IEEE Neural Networks Pioneer Award in 2000, the IEEE Browder J. Thompson Memorial Prize in 1972, the IEEE W. R. G. Baker Prize in 1978, the Frederick Emmons Award in 1974, and the M. E. Van Valkenhurg Award in 1995 and 1998; holder of 7 US patents and 8 honorary doctorates and recognized by the Institute of Scientific Information as one of the top 15 most-cited authors in all fields of engineering during 1991-2001.
Education:
Ph.D., University of Illinois, Urban-Champaign, 1964MSEE.,
Massachusetts Institute of Technology, 1961
BSEE, Mapua Institute of Technology, 1959
The applet shows a simulation of Chua's circuit, plotting the voltage measured across C1 against the voltage measured across C2. This corresponds to the display on an X-Y oscilloscope with probes connected across these capacitors. The initial values of the parameters used in the applet correspond to the component values in the circuit diagram, and show a simple periodic orbit (oscillation). The transition to chaotic dynamics can be found by carefully decreasing R or C1, (e.g. decrease R in steps of 0.01 to 1.2K). The simulation compares well with what is actually seen on an oscilloscope. Chaos seems to develop via a subharmonic cascade.
If you do not have access to an oscilloscope, you can use the voltage across C1 or C2 as the input to a high input impedance audio amplifier (with the component values shown the frequency of the oscillations is in the audio range). It turns out that the ear is very sensitive to the development of a weak subharmonic. The subharmonic becomes the fundamental an octave below the original tone, and the ear hears the note drop an octave even when the intensity of the new fundamental is very weak. The first two or three transitions in the subharmonic cascade route to chaos, and the onset of chaos (noise!) are very audible.

Considered as the Bill Gates of Asia.
3. DR. EDUARDO SAN JUAN
Moon Buggy Inventor
Filipinos consider Eduardo San Juan as the inventor of the Lunar Rover, or more popularly known as the Moon Buggy. The Moon Buggy was the car used by Neil Armstrong and other astronauts when they first explored the moon in 1969. Eduardo San Juan, a graduate of Mapua Institute of Technology (MIT), worked for Lockheed Corporation and conceptualized the design of the Moon Buggy that the Apollo astronauts used while in the moon. As a NASA engineer, San Juan reportedly used his Filipino ingenuity to build a vehicle that would run outside the Earth's atmosphere. He constructed his model using homemade materials. In 1978, San Juan received one of the Ten Outstanding Men (TOM) awards in science and technology.
Eduardo San Juan - Filipino Inventor: Mechanical engineer, Eduardo San Juan (aka The Space Junkman) worked on the team that invented the Lunar Rover or Moon Buggy. Eduardo San Juan is considered the primary designer of the Lunar Rover. San Juan was also the designer for the Articulated Wheel System. Prior, to the Apollo Program, Eduardo San Juan worked on the Intercontinental Ballistic Missile (ICBM).
Moon Buggy: In 1971, the Moon Buggy was first used by during the Apollo 12 landing to explore the Moon.
Eduardo San Juan - Education & Awards: Eduardo San Juan graduated from Mapua Institute of Technology. He then studied Nuclear Engineering at the University of Washington. In 1978, San Juan received one of the Ten Outstanding Men (TOM) awards in science and technology.
4. DR. ARTURO ALCARAZ
Arturo Pineda Alcaraz
ARTURO PINEDA ALCARAZ was born in Manila, the Philippines, on March 21, 1916, the second child of Conrado Alcaraz and Paz Pineda. As a government auditor the elder Alcaraz moved frequently, so his five children attended schools in a number of different towns. ARTURO completed elementary school at Lucena, Quezon Province, in southern Luzon, in 1929. His father was then transferred to Camarines Norte, where ARTURO took his first year of high school, and then to Baguio City.
Going to high school in the cool hills of Baguio, which was then a pleasant small town, was a "wonderful experience" for the boy. In the early 1930s the region was enjoying a mining boom and Leopoldo Faustino, a cousin of his father and one of the first Filipinos to earn a doctorate in geology, was then Head of the Division of Mines of the Bureau of Science. He spoke so highly to the young man of mining as a career that when ALCARAZ graduated at the top of his class from Baguio City High School in 1933, he sought to prepare for that profession. Since there was no school of mining in the Philippines, he entered the College of Engineering, University of the Philippines in Manila. A year later when Mapua Institute of Technology, also in Manila, offered a degree in mining engineering, ALCARAZ transferred there, receiving a Bachelor of Science in Mining Engineering from Mapua in 1937.
Arturo Alcaraz - Volcanologist: Doctor Arturo Alcaraz is a volcanologist specializing in geothermal energy development. In 1967, Arturo Alcaraz and team powered an electric light bulb using steam-powered electricity, Power coming from a Volcano near the town of Tiwi. This was the first geothermal power generated in the Philippines.
ALCARAZ is the First Prominent expert in the field of Geothermal Energy and Mining.
