The Software & System Engineering Essentials VuSpec integrates an abundant spectrum of features and content that is ideal for students, intro professionals, and practitioners. In addition to the PDF standards, this collection includes the landmark IEEE Guide to the Software Engineering Body of Knowledge (SWEBOK).
The resonance method in general is covered in the I R E Standards on Piezoelectric Crystals, 1958 [3]. Procedures are described in the Standards on Piezoelectric Crystals, 1957 [2], and in the literature [ 6 ] - [8], The transmission method is used for determination of fm, the frequency at minimum impedance of the sample. In addition to this measurement, the present Standard also specifies the measurement of the frequency at maximum impedance fn. A simplification of the transmission network in… read more the 1957 Standard (Fig. 4) may be used in view of the range of parameters found in the ceramics. This simplified circuit is shown in Fig. 1. The signal generator should have an output impedance lower than the minimum impedance of the test specimen. read less
Reliability data gathereed from equipment reliability surveys and analyses over a period of 35 years or more is summarized in this collection. Equipment surveys conducted prior to 1976, detailed reports on the surveys and data collection efforts, and extensive lists of references on equipment reliability are presented. The collection provides the analyst with options for determining reliability parameters for older electrical systems.
