– This paper describes a hierarchical evolutionary technique developed to design and train feedforward neural networks with different activation functions on their hidden layer neurons (Heterogeneous Neural Networks). At an upper level, a genetic algorithm is used to determine the number of neurons in the hidden layer and the type of the activation function(More)
This paper describes research investigating the evolution of coordination strategies in robot soccer teams. Each player (viewed as an agent) is provided with a common set of skills and is assigned to perform over a delimited area inside a soccer field. The idea is to optimize the whole team behavior by means of a spatial co- adaptation process in which new(More)
—Booting operating systems over the network is a well established method to simplify system administration in medium to large computer environments. Remote booting Linux and using PXE based environments for large scale system deployments are widely adopted by many system administrators. While scaling very well in controlled subnets they can not easily cross(More)

In this paper we focus on the aggregate query model implemented over NoSQL document-stores for read-mostly data bases. We discuss that the aggregate query model can be a good fit for read-mostly databases if the following design requirements are met: on-line time range queries, aggregates with predefined filters, frequent schema evolution and no ad-hoc. In(More)
This work investigates, whether openEHR with its reference model, archetypes and templates is suitable for the digital representation of demographic as well as clinical data. Moreover, it elaborates openEHR as a tool for modelling Hospital Information Systems on a regional level based on a national logical infrastructure. OpenEHR is a dual model approach(More)
