UML dialect for designing object-relational databases

The market trends indicate that the next generation database technology will be dominated by object-relational systems. This shift to the new technology calls for visual modeling techniques to facilitate the design of object-relational database systems. Even though Unified Modeling Language (UML) is not currently equiped to manage this task, it can be extended for it.The paper defines design co...

Towards designing artificial universes for artificial agents under interaction closure

We are interested in designing artificial universes for artificial agents. We view artificial agents as networks of highlevel processes on top of of a low-level detailed-description system. We require that the high-level processes have some intrinsic explanatory power and we introduce an extension of informational closure namely interaction closure to capture this. Then we derive a method to de...

Relational Formalism for the Management of Spatial Data Short Title: Relational Formalism for Spatial Data

Operations on spatial objects have much individuality. As a consequence, the spatial data modelling approaches, which have been proposed, have to consider either data types of the form set of spatial objects or non-1NF data structures or a limited spatial functionality of the operations. The model formalised in this paper overcomes these limitations. In particular, spatial quanta are defined an...

Spatial-temporal wind field prediction by Artificial Neural Networks

The prediction of near surface wind speed is becoming increasingly vital for the operation of electrical energy grids as the capacity of installed wind power grows. The majority of predictive wind speed modeling has focused on point-based time-series forecasting. Effectively balancing demand and supply in the presence of distributed wind turbine electricity generation, however, requires the pre...
