Vibration Testing - NASA

Services Provided Simulations of broadband random vibrations induced in spacecraft by external acoustic pressures Sine sweeps to identify resonances Broadband random environments that do not simulate mission conditions but are appropriate for precipitating impending failures due to workmanship defects Vibration of hazardous test articles, including pressurized systems and explosive materials Vibration in a thermal environment Vibroacoustic structural Testing to high sound pressure levels of large structures, components, and small subsystems Modal characteristics Natural frequencies Damping ratios Mode shapes Mathematical or FEA model correlation Vibration Testing Rocket boosters and spacecraft are subject to intense acoustic environments during launch, which induce high levels of Vibration in structural elements and equipment.

Several filter manufacturers, including K&L Microwave, TTE, and Allen Avionics, Inc., provide excellent filters for ADC testing. There are two types of filters that are often used for ADC testing: low-pass filters and band-pass filters. These can be used

Population Genetics and the Hardy-Weinberg Principle

Testing for Genetic Equilibrium . We can check if a population is in genetic equilibrium by testing if the Hardy-Weinberg principle applies, as follows: Given the population genotype numbers, (1) calculate the allele frequencies from the observed population genotype numbers. (2) calculate the genotype frequencies from the observed genotype numbers.
