Combinational logic for generating gate drive signals for phase control rectifiers [PDF]
, 1982 Control signals for phase-delay rectifiers, which require a variable firing angle that ranges from 0 deg to 180 deg, are derived from line-to-line 3-phase signals and both positive and negative firing angle control signals which are generated by ...

Gene Expression Noise Facilitates Adaptation and Drug Resistance Independently of Mutation
, 2011 We show that the effect of stress on the reproductive fitness of noisy cell populations can be modelled as first-passage time problem, and demonstrate that even relatively short-lived fluctuations in gene expression can ensure long-term survival of a ...

Noise Immunity of Binary Chirp Signals
Proceedings of Telecommunication UniversitiesThe results of a study of the noise immunity of receiving signals with linear frequency modulation in telecommunication information transmission systems are considered. Analytical expressions for the synthesis of binary signals by linear frequency modulation with control parameters are obtained.
