Electronic governance and organizational transformation
Proceedings of the 1st international conference on Theory and practice of electronic governance, 2007The role of information and information technology in the transformation of public agencies is well understood to be central. The challenge governments face is understanding the nature of that role and leveraging it in the process of governmental transformation.

Multifunctional Electronic Transformer
2019 16th Conference on Electrical Machines, Drives and Power Systems (ELMA), 2019The use of high-frequency transformers in combination with synchronous reversible rectifiers-inverters and microprocessor-based control systems allows you to manage the exchange of energy between objects of the electrical network while simultaneously stabilizing the voltage, which improves the quality and reliability of power supply to consumers ...

An Adaptive Electronic Hybrid Transformer
IEEE Transactions on Communications, 1972A hybrid transformer is used to couple simultaneously both a transmitter and a receiver to the same end of a telephone line with minimum crosstalk. Under ideal circumstances the transformer provides a cancellation signal at the input terminals of the receiver to exactly cancel the signal induced by the local transmitter.

Orbital transformations and configurational transformations of electronic wavefunctions
The Journal of Chemical Physics, 1999Transformations among molecular orbitals are often expedient or illuminating, and sometimes essential in quantum chemical contexts. In order to express the many-electron wavefunction in terms of the corresponding transformed configurations, full CI calculations used to be repeated in the transformed orbital basis.

Fock similarity transformation of the electronic Hamiltonian
The Journal of Chemical Physics, 2022The covariance of the one-electron Schrödinger equation in a gauge transformation of electromagnetic potentials is customarily discussed, introducing the relationships that describe their changes, induced by a generating function of position coordinates and time, together with a phase transformation of the wavefunction, according to a proposal by Fock,

A Multiport Power Electronic Transformer with Shared Medium-frequency Transformer
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020The existing power electronic transformer (PET) topologies are governed by the low power density, high cost and large size. Therefore, a multiport PET topology based on modular multilevel converter with the shared medium-frequency transformer (MFT) is proposed in this paper, where the proposed PET can provide four voltage interfaces, including medium ...

A Power Electronic-Based Distribution Transformer
IEEE Power Engineering Review, 2002The distribution transformer has been in use by utilities throughout the twentieth century. Until now, it has consisted of a configuration of iron or steel cores and copper/aluminum coils, with mineral oil serving as both coolant and dielectric medium.

The transformation of electronic communications
Electrical Engineering, 1959A DIFFICULTY FACING all of us who summarize various portions of technological history in the past quarter century for this anniversary issue of Electrical Engineering is the utter distortion of the once comfortable relationship between time and technical progress. In a previous generation, the historian assigned himself a century or more of engineering
