Due to the absence of commonly accepted conceptual and formal foundations for workflow management, and more generally Business Process Management (BPM), a plethora of approaches to process modelling and execution exists both in academia and in industry. The introduction of workflow patterns provided a deep and language independent understanding of modelling issues and requirements encountered i...

A new method for shape learning is presented in this paper. This method incorporates abilities from both statistical and structural pattern recognition approaches to shape analysis. It borrows from statistical pattern recognition the capability of modelling sets of point coordinates, and from structural pattern recognition the ability of dealing with highly irregular patterns, such as those gen...

Modelling the groundwater contamination in the aquifer above a repository for high-level nuclear waste is a complex task. The usual procedure is based on modelling the transport of radionuclides in one or two dimensions only (NAGRA, 2002; Kosakowski, 2004; Keesmann et al., 2006; SKB, 2006; Nykyri et al., 2008). However, modern computing techniques allow to perform simulations in three dimension...

Owing to the ever-growing impetus towards development of eco-friendly and low carbon footprint energy solutions, biodiesel production usage have been subject tremendous research efforts. The process is driven by several parameters, which must be maintained at optimum levels ensure high productivity. Since productivity quality are also dependent on various raw materials involved in transesterifi...
