Evolution of timekeeping from water clock to quartz clock -- the curious case of the Bulova ACCUTRON 214 the first transistorized wristwatch
Edval J. P. Santos
The technological discoveries and developments since dawn of civilization that resulted in the modern wristwatch are linked to the evolution of Science itself. A history of over 60…
Large-Signal and High--Frequency Analysis of Nonuniformly Doped or Shaped PN-Junction Diodes
Anatoly A. Barybin, Edval J. P. Santos
An analytical theory of non-uniformly doped or shaped PN-junction diodes submitted to large-signals at high frequencies is presented. The resulting expressions can be useful to eva…
Systematic Oil Flow Modeling in the Quasi-3D Approximation Yields Additional Terms that Allows for Variable Cross-Section Area Tubing
Edval J. P. Santos
A systematic model development for oil flow in quasi-3D (1D + 2D) is presented. Our approach provides a unified modeling scheme. Besides, additional terms are obtained, which allow…
Unified Approach to the Large-Signal and High-Frequency Theory of -Junctions
Anatoly A. Barybin, Edval J. P. Santos
Spectral approach to the charge carrier transport in -junctions has allowed us to revise the theoretical results relating to large signal operation of the junction to make the…
Transverse Averaging Technique for Depletion Capacitance of Nonuniform PN-Junctions
Anatoly A. Barybin, Edval J. P. Santos
This article evolves an analytical theory of nonuniform -junctions by employing the transverse averaging technique (TAT) to reduce the three-dimensional semiconductor equations…
High quality c-axis oriented ZnO thin-film obtained at very low pre-heating temperature
A. M. P. Santos, Edval J. P. Santos
Highly oriented ZnO thin-film has been obtained at a very low pre-heating temperature, with the spin-coating sol-gel technique. The dependence of the c-axis orientation on the pre-…
