A constant temperature operation thermoresistive sigma–delta solar radiometer
(2006)
In this paper we propose a feedback system, with thermoresistive sensor, based on sigma–delta modulation. This system uses an one-bit sigma–delta modulator in which considerable part of conversion functions is performed ...
Theoretical Substituent Electrophilicities
(SOC BRASILEIRA QUIMICA, 2011)
A Hammett-like equation, relating theoretical global and substituent electrophilicities, is derived for substituted ethylenes and benzoic acids, allowing the calculation of electrophilic substituent constants a.. Correlations ...
