TY - JOUR A1 - Czarnecki, Christian A1 - Geier, Jari A1 - Pflug, Karolin T1 - Netzvirtualisierung durch SDN und NFV : Unternehmensprozesse auf dem Prüfstand JF - LANline N2 - Kundenanforderungen an Netzwerke haben sich in den vergangenen Jahren stark verändert. Mit NFV und SDN sind Unternehmen technisch in der Lage, diesen gerecht zu werden. Die Provider stehen jedoch vor großen Herausforderungen: Insbesondere Produkte und Prozesse müssen angepasst und agiler werden, um die Stärken von NFV und SDN zum Kundenvorteil auszuspielen.

Eine differenzierte Auseinandersetzung mit der Problematik, ob und unter welchen Umständen virtuelle Identitäten dem Datenschutzrecht unterfallen, fehlt bislang. Der vorliegende Beitrag gibt einen Überblick über den Schutz virtueller Identitäten und zeigt Ansätze auf, mittels derer bestimmt werden kann, wann virtuelle Identitäten nach Inkrafttreten der DSGVO durch das Datenschutzrecht geschützt werden.

We present an elementary straightforward proof of this result. The likelihood ratio test for testing the hypothesis that the covariance structure is of the assumed special form is derived and discussed. Applications to real data are given.

Conditions characterizing the superiority of a procedure are given in terms of population canonical correlation type coefficients. Statistical tests for checking these conditions are developed. Test statistics based on the eigenvalues of a symmetrized sample cross-covariance matrix are suggested, as well as test statistics based on sample canonical correlation type coefficients.

An equivalent macro-element constituted by a set of six trusses, two for each transverse, longitudinal and diagonal direction, is introduced. The equivalent trusses, whose stiffness is calculated by fully modeled vaults of different geometry, mechanical properties and boundary conditions, simulate the vault in both global analysis and local analysis, such as kinematic or rocking approaches. A parametric study was carried out to investigate the influence of geometrical characteristics and mechanical features on the equivalent stiffness values. The method was numerically validated by performing modal and transient analysis on a three naves-church in the elastic range. Vibration modes and displacement time-histories were compared showing satisfying agreement between the complete and the simplified models. This procedure is particularly useful in engineering practice because it allows to assess, in a simplified way, the effectiveness of strengthening interventions for reducing horizontal relative displacements between vault supports.
