This paper describes the need for understanding the role of financial markets in successful product development in the global context. Agent-based models distinguish themselves by their ability to generate many real world phenomena endogenously, rather than as a result of ad-hoc assumptions. We report on a model of global financial markets employing the following agents: countries, firms, stock traders, country banks, and a global bank. These agents interact with goods, credit, currency, and stock markets. The model endogenously generated quantitative and qualitative features of real economies, including skewed firm sizes, skewed country GNP’s, skewed stock trader portfolio values, and heavy-tailed non-Gaussian firm growth rate, exchange rate fluctuation, and stock return distributions. Multiple runs were performed with different random number generator seeds to investigate the stability or instability of the economies grown by the model. Both stable and unstable country economies were detected. The multiple runs also verified conclusions drawn from analyzing individual runs showing how small countries could be buffeted by fluctuations in larger countries. Such a model can be used by product development organizations to understand the impacts of their product development decisions in the context of dynamic and unpredictable financial markets.

Inputs And Outputs

Linear dynamical systems where both inputs and outputs are contaminated by errors are considered. A characterization of the sets of all observationally equivalent transfer functions is given, the role of the causality assumption is investigated and conditions for identifiability in the case of Gaussian as well as non-Gaussian observations are derived.

Nonsmooth Mappings

We compare different notions of differentiability of a measure along a vector field on a locally convex space. We consider in the L2-space of a differentiable measure the analog of the classical concepts of gradient, divergence and Laplacian (which coincides with the Ornstein–Uhlenbeck operator in the Gaussian case). We use these operators for the extension of the basic results of Malliavin and Stroock on the smoothness of finite dimensional image measures under certain nonsmooth mappings to the case of non-Gaussian measures. The proof of this extension is quite straight forward and does not use any Chaos-decomposition. Finally, the role of this Laplacian in the procedure of quantization of anharmonic oscillators is discussed.

Monochromatic Illumination

Photoconductivity decay during monochromatic illumination has been measured on an ensemble of a-Si:H films deposited at different substrate temperatures. Degradation behaviour has been modelled within the framework of the bond-breaking model (dN/dt = Csw np). Simmons and Taylor recombination kinetics has been assumed, taking into account the divalent nature of dangling bonds and their three possible conditions of occupancy. The Staebler-Wronski susceptibility (Csw) has been extracted through a fitting procedure. As a result, a correlation between the obtained Csw and the measured electronic, optical and structural properties of as deposited a-Si:H films can be inferred.

Recombination Kinetics

The DSC recombination kinetics was studied up to 100 °C without electrolyte leakage or external contamination using a unique laser assisted glass sealing process. In addition to temperature having a strong influence on the recombination reaction rate, the energy of the exited electrons was found to be critical for determining the recombination activation energy.

Shallow Traps

The continuous-time-random-walk (CTRW) model which was developed for electron scavenging reactions in polar glasses is extended to the phenomenon of spectral relaxation of electrons in shallow traps et− in a wider range of systems. The central role of electron-phonon coupling in understanding the initial electron localization, the "pre-existing trap", and electron transfer processes are emphasized. The reactivity of et− with scavengers, including protons, is discussed in terms of the theory of multi-phonon non-radiative transitions.
