Exact-diagonalization results for Kondo nanoclusters alloyed with mixed-valence impurities show that tuning the energy spacing Δ drives the system from the Kondo to the Ruderman-Kittel-Kasuya-Yosida (RKKY) regime. The interplay of Δ and disorder gives rise to a Δ versus concentration T=0 phase diagram very rich in structure. The parity of the total number of electrons alters the competition betwee

Industry--academia collaboration is critical for empirical research to exist. However, there are many obstacles in the collaboration process. This paper reports on the experiences gained by the author, in a 2-year collaboration project on software testing which involved on-site work by the researcher in the industry premises. Based on notes, minutes of meetings, and progress reports, the project h

To meet the demands of high electrical efficiencies in combination with low emissions for gas turbine-based power plants, wet cycles have gained new interest. The combustion chamber is a key component in such a power plant. Detailed investigations are necessary to gain insight into the formation of hazardous emissions such as CO and NOx. In this paper, computational fluid dynamics (CFD) has been e

There are many fashion words in AI, such as introspection, reflection, metalanguage, belief and intention. The usual way of looking at such concepts is proof theoretical even if it is not at all clear that these concepts can be described in a formal language. I shed light on some of these concepts from a semantical point of view, and show that it is impossible to describe them to a computer. This

Widespread availability of location aware devices (such as GPS receivers) promotes capture of detailed movement trajectories of people, animals, vehicles and other moving objects, opening new options for a better understanding of the processes involved. In this paper we investigate spatio-temporal movement patterns in large tracking data sets. We present a natural definition of the pattern 'one ob
