The literature review presented in this chapter describes the DOT certification programs and how they were developed in different ways, in part due to the flexibility found in 23 CFR 637B. Included is ...

Materials testing is a respected and established technique that is used to ascertain both the physical and mechanical properties of raw materials and components. It can be used to examine almost ...

Materials testing is a well-established technique used to determine the physical and mechanical properties of raw materials and components from a human hair to steel, composite materials and ceramics.

Coherent interleaved sampling is a new technique that can acquire data faster with more data points than sequential sampling. Engineers who need to characterize semiconductor devices, high-speed ...

Low-frequency signals appearing on the power lines—so what? The level is low relative to the primary power for an AC-powered device. And DC-powered systems are designed to function with wide variance ...

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

The practices and methods listed were compiled from information found on the DOT’s website or from a document or documents on their website. AASHTO standard specifications begin with an “M,” practices ...
