The electronic structure of the superconducting ground state of YBa2Cu3O7 ceramics is calculated at the MP2 electron correlation level using the self-consistent embedded-cluster method. The [Cu3O12]14− quantum cluster is embedded in a finite array of point charges which produce the correct value of the Madelung potential at each cluster site. The results obtained reveal the strong influence of ...

The laws of Newtonian mechanics allow ab-initio molecular dynamics to model and simulate particle trajectories in material science by defining a differentiable potential function. This paper discusses some considerations for the coding of ab-initio programs for simulation on a standalone computer and illustrates the approach by C language codes in the context of embedded metallic atoms in the f...

The spontaneous emission dynamics of atoms embedded in an omnidirectional waveguide (ODWG), a novel optical waveguide, is studied on the basis of the complete reflection of one-dimensional photonic crystals. With the dispersion curve of the single waveguide mode within the photonic band gap and various extents of background dissipation, we characterize the photon-atom interaction in the ODWG. T...

The ionization potential of an ion embedded in a plasma is lowered due to the whole charged particles (ions and electrons) interacting with that ion. It is the so called plasma effect. The numerical plasma model developed years ago, based on classical molecular dynamics, capable to describe a neutral plasma at equilibrium involving ions of various charge states of the same atom together with el...

This paper proposes a novel method to transplant emotions to a new speaker in statistical speech synthesis based on an emotion additive model (EAM), which represents the differences between emotional and neutral voices. This method trains EAM using neutral and emotional speech data of multiple speakers and applies it to a neutral voice model of a new speaker (target). There is some degradation ...

Banken und Versicherungen gehören zu den softwareintensiven Branchen, die große Anwendungslandschaften managen und weiterentwickeln müssen, die im Regelfall unter Benutzung vieler Technologiegenerationen implementiert wurden. Als Baukasten dazu bieten sich Methoden des Enterprise Architecture Managements (EAM) an. Im Rahmen einer eintägigen Sonderveranstaltung soll aufgezeigt werden, wohin sich...
