Global systems – systems which may operate over transient networks including mobile elements and in which computation itself may be mobile – are gaining in importance. Nevertheless, the means for their modelling are still underdeveloped. The Unified Modelling Language (UML) is well developed for convenient modelling of behavior, but is not yet so useful for modelling aspects of design relevant ...

Using density functional theory (B3LYP functional) we systematically studied Pt/Ni alloy clusters (6 44 atoms) and found that the Pt/Ni(1 1 1) alloy surface prefers the bulk structure (Pt3Ni crystal), without showing surface segregation. This leads to an ordered surface with each Ni surrounded by 6 Pt atoms. We then examined the oxygen chemisorption at all surface sites and found strongest bind...

OBJECTIVES The aim of the present study was to evaluate the functional mobility and its relationship to cognitive ability in patients with type 2 diabetes (T2DM), age between 50 and 65 years and under 10 years of diagnosis. MATERIALS AND METHODS An observational, analytical and cross-sectional study, involving no diabetic and type 2 diabetic individuals with inadequate glycemic control, selec...

In this work we introduce the mobility-tree construct for high-level functional representation of complex 3D indoor scenes. In recent years, digital indoor scenes are becoming increasingly popular, consisting of detailed geometry and complex functionalities. These scenes often consist of objects that reoccur in various poses and interrelate with each other. In this work we analyze the reoccurre...

An assessment of several widely used exchange-correlation potentials in computing charge-transfer integrals is performed. In particular, we employ the recently proposed Coulomb-attenuated model which was proven by other authors to improve upon conventional functionals in the case of charge-transfer excitations. For further validation, two distinct approaches to compute the property in question ...
