Experience shows that in systems where process executions are not strictly enforced by process models, often deviations occur. Alignments between logged process executions and models reveal useful insights and can be used for both conformance checking and performance analysis. In this article, we present a memory-efficient approach using marking equations of Petri nets to calculate optimal alig...

Cochlear implants are the first and until now the only existing prosthesis that can substitute an entire sensory system – the hearing system – nearly completely. After implantation and a period of rehabilitation, most deaf patients are able to use the telephone or listen to the radio with their cochlear implant system. Although top performing cochlear implant subjects understand speech nearly p...

In the context of missions accomplished jointly by an artifical agent and a human agent, we focus on a controller of the authority dynamics based on a dependence graph of resources that can be controlled by both agents. The controller is designed to adapt the behaviours of the artificial agent or of the human agent in case of an authority conflict occurring on these resources. The relative auth...

All standard Artifical Intelligence (AI) planners to-date can only handle a single objective, and the only way for them to take into account multiple objectives is by aggregation of the objectives. Furthermore, and in deep contrast with the single objective case, there exists no benchmark problems on which to test the algorithms for multi-objective planning. Divide-and-Evolve (DaE) is an evolut...

It is well known that the bioavailability of artifical radionuclides such as Sr, Cs and Pu in contaminated soils depends on the source term origin of the contamination. Altough the behaviour of the mentioned radionuclides in the soil is also influenced by the time passed from the contamination event and the characteristics of the contamination receiving soils. The objective of the present work ...

The Semantic Web adds a layer of logic and metadata to the current World Wide Web. By utilizing traditional Artifical Intelligence (AI) and Knowledge Representation (KR) techniques for both the construction of new documents and linking of existing ones, the Semantic Web facilitates machineto-machine (or ”agent-to-agent”) communication. Lisp’s proven reliability and flexibility in AI and KR make...

The aim of this paper is to substitute sociologically more pertinent explanations for the popular sociology notions of "interaction" and "hybrid society". The scope and implications of these notions are discussed from a perspective of microsociology as applied to distributed artifical intelligence. The authors argue that only a precise use of the terms in specific disciplinary contexts is condu...

A 2-layer thermoelectric generator was tested as a solution to increase the output of PV cell. number practical experiments were carried out on both single and two combined (TEG) configurations connected in series with photovoltaic (PV) cells load independently from each other. Testing performed using class AAA solar simulator system Sol3A under real outdoor weather conditions. The results show...

Numerous applications, from high-performance scientific computing to large, highresolution multi-touch interfaces to strong artifical intelligence, push the practical physical limits of modern computers. Typical computers attempt to hide the physics as much as possible, running software composed of a series of instructions drawn from an arbitrary set to be executed upon data that can be accesse...

Bacteria offer an evolutionary model in which rich interactions between phenotype and genotype lead to compact genomes with efficient metabolic pathways. Central to this is the expression and folding of sequences of amino acids to form proteins. We seek an analogous process that supports a rich artificial heredity. These systems can be simulated by stochastic chemistry models, but there is curr...
