1.1 This test method covers the nondestructive determination of thickness of bound pavement layers using short-pulse radar.

1.2 The accuracy and applicability of this test method is a function of these components: radar-system penetration, radar-system resolution, and the dielectric const...

1.1 This specification covers lead sheet, strip, and plate of various alloys intended for use in chemical plants, sound attenuation, roofing, vibration dampening, flashing and weather stripping, waterproofing, and radiation shielding.

1.2 The values stated in inch-pound units are to be re...

1.1 This test method permits the rapid measurement of apparent relative permittivity and loss tangent (dissipation factor) of metal-clad polymer-based circuit substrates in the X-band (8 to 12.4 GHz).

1.2 This test method is suitable for testing PTFE (polytetrafluorethylene) impregnated gl...

Different modalities in biomedical images, like CT, MRI and PET scanners, provide detailed cross-sectional views of human anatomy. This paper introduces three-dimensional brain reconstruction based on CT slices. It contains filtering, fuzzy segmentation, matching method of contours, cell array struc...

The history of the development of Chinese telemetry is introduced in the paper. The new telemetry ground station and the new onboard space telemetry system, with the idea of systematic design and the specification, are described.
