1.1 These methods cover procedures for planing, shaping, turning, mortising, boring, and sanding; all of which are common wood-working operations used in the manufacture of wood products. These tests apply, in different degrees, to two general classes of materials:

1.1.1 Wood in the form ...

1.1 This guide covers general procedures for the material selection and fabrication of reference blocks made of metal or metal alloys and intended to be used for the pulsed longitudinal wave ultrasonic examination of the same or similar production materials.

1.2 This guide covers the fabri...

1.1 This practice covers the selection and application of strain gages and associated instrumentation for the measurement of static strain up to and including the temperature range from 425 to 650°C (800 to 1200°F). This practice reflects some current state-of-the-art techniques in high t...

With the development of CMOS and MEMS technologies, the implementation of a large number of wireless distributed micro-sensors that can be easily and rapidly deployed to form highly redundant, self-configuring, and ad hoc sensor networks. To facilitate ease of deployment, these sensors operate on ba...

The tapered slot antenna, such as Vivaldi, has been widely used due to its ultra-wideband, high gain, simple feed structure, and easy fabrication. However, there is no rigorous analytical theory for this type of antenna. This paper analyzed the metal parts of a tapered slot antenna in a conical coor...
