DICTIONARY OF GEOPHYSICS, ASTROPHYSICS, and ASTRONOMY
index notation A notation of ten-sors in terms of their component index structure(introduced by R. Penrose). For example, thetensor T (θ, θ) = T ba θ ⊗ θb is written in theabstract index notation as T ba , where the indicessignify the valence and should not be assigneda numerical value. When components need tobe referred to, these may be enclosed in matrix<lb...
متن کاملMaintainability Policy for Deteriorating System with Inspection and Common Cause Failure (TECHNICAL NOTE)
A condition based preventive and corrective maintenance policy is proposed for a continuously operating system. The condition of the system is assumed to deteriorate with time. The model incorporates both deterioration as well as random common cause failures. The deterioration stages are modeled as discrete state processes. The system is put to random inspection to know the condition. The mean ...

متن کاملRadio Astronomy: A Revision of Chapter 22, Handbook of Geophysics and Space Environments
This survey is a summary of available information on radiation environments at radio frequencies (about 10 m to 1 cm wavelength); the Moon, the Planets, and space beyond the solar system are described. The topics presented are refraction and absorption of extraterrestrial radio waves by the Earth's atmosphere, radio and radar observations of the Mo^n and Planets, radio emission from the celesti...
متن کاملDeveloping a method for reliability allocation of series-parallel systems by considering common cause failure
Reliability allocation has an essential connection to design for reliability and is an important activity in the product design and development process. In determining the reliability of subsystems or components on the basis of goal reliability, attention must be paid to failure effect, failure information, and improvement opportunities based upon real potentials for reliability improvement. In...
