Power/frequency scalability. 10. Sample Rate, Nyquist Frequency & Aliasing. 2. Nyquist Frequency. The Nyquist frequency is equal to one-half the sampling rate. .. Shannon’s sampling theorem states that a sampled time signal must not contain components at frequencies above the Nyquist frequency. . 2. TEST A. What is the single most important property of vibrating structure?. What happens when structure is vibrating in resonance?. What controls the amplitude if excitation frequency equals the resonant frequency?. Saeed Ziaei-Rad. Modal Analysis and Testing. 2. Single Degree-of-Freedom (SDOF). Undamped. Viscously Damped.

Data mining and text analysis is becoming increasingly important in the field of counter-terrorism.. Over the past 10 years terrorists have started to use technology to obtain new members, communicate and conduct illegal activities. It is therefore very important that the relevant agencies have the tools to detect and identify. . Tlamacazapa. , Guerrero, Mexico. Robin Lynch. Hydrology. April 29,2010. Tlamacazapa. , Guerrero.
