The invention
of the year ceremony was held at NASA Headquarters on Thursday,
June 5th. This event recognized Dr. Norden E. Huang's mathematical
method called Computer Implemented Empirical Mode Decomposition
Method, also known as the Hilbert-Huang Transformation (HHT) Method.
Dr. Huang is the Director of the Goddard Institute of Data Analysis
and winner of the NASA Government Invention of the Year. Dr. Huang
has also won NASA's Exceptional Space Act Award in 1999, for which
he was cited, "as having invented one of the most important
applied mathematical methods in NASA's history," for his invention
of the HHT Method.
The HHT Method
has many diverse applications. The Method can be applied in a variety
of fields to study things such as: basic nonlinear mechanics, climate
cycles, solar neutrinos variations, earthquake engineering, geophysical
exploration, submarine design, structural damage detection, satellite
data analysis, nonlinear wave evolution, turbulence flow, blood
pressure variations and heart arrhythmia.
This Method
is also used to analyze sea surface temperature data collected by
NASA satellites and instruments. The National Oceanic and Atmospheric
Administration uses Huang's method to analyze images from some of
its Earth orbiting spacecraft. It has proven successful in connecting
environmental changes to El Nino phenomena with weather changes.
