According to Barsalou (1992) frames as recursive attribute-value structures form the general format of cognitive concepts. Based on empirical research, Barsalou’s focus in developing frame theory was not on providing a formal theory. Our project proposes to both sharpen and generalize his intuitive conceptions by developing an adequate formal model for frames. Our goal is to obtain a better und...

Applied Nonlinear Optimization in the DFG-Center

Modelling and simulation of complex processes in key technologies are the main issues of the DFG Research Center. Being able to efficiently deal with the complex models established and having the corresponding mathematical basis available, engineers and practitioners are interested in optimizing these models according to some objective. This is reflected by several scientific projects in the Ce...

Optimized terahertz-wave generation using BNA-DFG.

An effective and widely tunable means of producing terahertz (THz) radiation using difference-frequency generation (DFG) in an organic N-benzyl-2-methyl-4-nitroaniline (BNA) crystal was demonstrated by optimizing the pump wavelengths. We calculated the (wideband) refractive index and coherence length mapping of BNA to establish the optimum phase-matching condition of the DFG configuration. To s...
