fS/2C, is referred to as the frequency resolution of the DDS. Inspection of the fOfrequency set indicates that the modulus of the DDS accumulator, namely 2C, determines both the frequency resolution of the DDS and the number of possible output frequencies. For example...
structure undergoes a shift in strain, measured in terms of deviator stress (δd). There is a progressive reduction in plastic strain, with the rate of increase in plastic strain declining and almost stagnating with successive stress cycles. Recoverable axial strain represents the resilient modulus (...

UCS and residual strength. Additionally, properties such as tensile strength and toughness were positively correlated with the polypropylene fiber content. Furthermore, there was a negative linear correlation between the number of cycles and the dynamic elastic modulus and damping of IOTs modified with...

The formula may be somewhat accurate for just measuring one property, such as Young’s modulus, but will fail to predict both Yong’s modulus and residual stress due to the insufficient accuracy of the formula.fn=n2π2L2Eh212ρ+σL2n2π2ρwhere n is the mode number, L is the length,...
The success of expensive tube units, however, has prompted a number of manufacturers to offer "budget" tube preamplifiers. Though still not cheap, they come in at prices just a bit higher than the least expensive solid-state preamps (Hafler, Kenwood, etc.). Consequently these lower-cost tu...
