A Theory of Value for Service Ecosystems

In this thesis, we present a theory of value for the design and analysis of service ecosystems. The theory is based on general systems thinking. The concept of a system is used for relating knowledge from different disciplines (such as software engineering ...

Stereodynamics of Ne(3P2) reacting with Ar, Kr, Xe, and N2

Andreas Osterwalder, Sean Dennis Steven Gordon, Junwen Zou, Silvia Tanteri

Stereodynamics experiments of Ne(3P2) reacting with Ar, Kr, Xe, and N2 leading to Penning and associative ionization have been performed in a crossed molecular beam apparatus. A curved magnetic hexapole was used to state-select and polarize Ne(3P2) atoms w ...

L'urbanisme de l'entre-deux

Jade Rudler

The democratization of vehicles has often reduced the public space to a place of circulation. For the last fifteen years, the habits of mobility have evolved: a system centered around the automobile leaves room for compositions between different modes of d ...

Acoustic dispersive prism

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

The optical dispersive prism is a well-studied element, which allows separating white light into its constituent spectral colors, and stands in nature as water droplets. In analogy to this definition, the acoustic dispersive prism should be an acoustic dev ...

Experimental verification of the method for producing a three-dimensional cross-pairs metamaterial structure based on a dielectric AlN cube

Przemyslaw Andrzej Gorski

This paper presents a method of manufacturing 3D metamaterial structures using laser radiation. Our proposed material, aluminum nitride (AlN), by interaction of a high-energy laser beam undergoes a direct metallization process, a result of which a conducti ...

Energetics of dislocation transformations in hcp metals

William Curtin, Binglun Yin, Zhaoxuan Wu

Dislocation core structures of hcp metals are highly complex and differ significantly among the hcp family. Some dislocations undergo unconventional transformations that have significant effects on the material plastic flow. Here, the energetics of disloca ...

Effect of the presence of mortar joints in the bond behaviour of tuff masonry elements

Angelo Garofano

In this paper, the bond behaviour of masonry elements made of tuff stone and bonded with different types of FRP fabrics (glass, carbon, basalt) has been investigated through an experimental campaign. Tuff is a natural stone representing a very common base ...

Neutron resonance spin-echo upgrade at the three-axis spectrometer FLEXX

Thomas Keller, Felix Groitl

We describe the upgrade of the neutron resonance spin-echo setup at the cold neutron triple-axis spectrometer FLEXX at the BER II neutron source at the Helmholtz-Zentrum Berlin. The parameters of redesigned key components are discussed, including the radio ...
