Best linear invariant estimators of log reliable life are derived for a model in which failure times have a two-parameter Weibull distribution and removal of some surviving items from life test is ...

Sufficient conditions are given for the existence, uniqueness and finite-dimensional approximation of the solution to a first-order infinite-dimensional vector differential equation. Given a suitable ...

Signals operating in the radio frequency (RF) realm between 3 kHz to 300 GHz are an inherent part of processing by circuit components within and outside an IC. Linear characteristics of RF circuits ...

Chirp signals are fast, accurate, and provide information that may be more difficult to obtain in other ways, as Mark A Martin, Jayant Datta and Xinhui Zhou explain. Figure 1: The frequencies of the ...
