The process of signal detection, feature/parameter estimation, clustering/data fusion and identification/classification is often called pattern recognition or signal interpretation.

Today, many online companies are gathering information and assembling sophisticated databases that know a great deal of information about many people, generally without the knowledge of those peopl

Measurements of the optical spectra of semiconductor injection lasers with deformed cylinder resonators show strong indications of the classical Kolmogorov-Arnold-Moser transition from integrabilit

The Kondo properties of the impurity Anderson model provide a theoretical framework for relating thermodynamic and angle integrated electron spectroscopy data in many heavy fermion materials.

Im Rahmen des BMBF-geförderten Forschungsprojekts CONDOR werden Netz-Architekturen und optische Technologien erarbeitet, die es erlauben, eine vielseitig nutzbare, weitestgehend transparente optisc

One of the major challenges of today's electric vehicles is its far from satisfactory energy storage capacity.

Via a resistively detected NMR technique, the nuclear spin-lattice relaxation time T-1 of Ga-71 has been measured in a GaAs/AlGaAs heterostructure containing two weakly coupled 2D electron systems

Convergent beam diffraction patterns from a bcc blue phase (BPI) monocrystal in an electric field applied in the [110] direction, show this 2-fold axis transforming through an orthorhombic distorti

In this paper, we review in detail experimental demonstrations of Kramers-Kronig (KK) based direct detection systems with high per-carrier interface rates, high spectral efficiencies, and ~100-km r

The simulation of electronic circuits involves the numerical solution of very large-scale, sparse, in general nonlinear, systems of differential-algebraic equations.
