   abstract = {The motivation for this paper is to investigate the use of alternative novel neural network architectures when applied to the task of forecasting and trading the ASE 20 Greek Index using only autoregressive terms as inputs. This is done by benchmarking the forecasting performance of 4 different neural network training algorithms with some traditional techniques, either statistical such as an autoregressive moving average model (ARMA), or technical such as a moving average convergence/divergence model (MACD), plus a naïve strategy. For the best training algorithm found, we used a genetic algorithm to find the best feature set, in order to enhance the performance of our models. More specifically, the trading performance of all models is investigated in a forecast and trading simulation on ASE 20 fixing time series over the period 2001-2009 using the last one and half year for out-of-sample testing. As it turns out, the combination of the neural network with genetic algorithm, does remarkably well and outperforms all other models in a simple trading simulation exercise and when more sophisticated trading strategies as transaction costs were applied.},

abstract={Enterprise integration is significant for the enforcement of novel business models in an enterprise/industry. The great heterogeneity of systems/applications in the enterprise environment requires the introduction of interoperability aspects in order to resolve integration problems in a flexible and dynamic way. Our approach introduces an advanced enterprise semantic model representing both enterprise structure and available services, through the use of ontologies. The model is associated by a specific architecture that uses the above model in combination with state-of-the-art technologies such as Web services and workflows},

abstract={It is well known that for the linear filtering problem with unknown time-invariant or time-varying parameters i.e. the adaptive filtering problem, the multimodel adaptive filter (MMAF) based on the Lainiotis (1973) partitioning theorem is the best solution. It is also known that genetic algorithms (GA) are one of the best methods for searching and optimisation. A new method which combines the effectiveness of MMAF and GAs robustness has been developed. The experiments' results, obtaining from the performance of this new method to a specific linear model with one unknown time-invariant parameter, indicate that the proposed method provides better estimation of the unknown parameter compared to that of a single MMAF},
