In recent decades, communication technology has advanced at unprecedented speed. A key breakthrough is semantic ...

We apply Dirac's method of quantization in the presence of a constraint to the hydrogen atom described by the R⁴ coordinates of Kustaanheimo and Stiefel. We show that the energy levels and their ...

We develop an optimal quantization approach for numerically solving nonlinear filtering problems associated with discrete-time or continuous-time state processes and discrete-time observations. Two ...

Semantic communications have revolutionized wireless communication in this century. In a new study, SeoulTech researchers have investigated ConcreteSC, a novel digital communication framework that ...
