Dynamic clustering for interval data based on L 2 distance

Summary  This paper introduces a partitioning clustering method for objects described by interval data. It follows the dynamic clustering approach and uses and L ₂ distance. Particular emphasis is put on the standardization problem where we propose and investigate three standardization techniques for interval-type variables. Moreover, various tools for cluster interpretation are presented and illustrated by simulated and real-case data.     

Biosynthesis of the Irregular C12-Terpenoid Dehydrogeosmin in Flower Heads of Rebutia marsoneri WERD. (Cactaceae)

Farnesol ( 3a ) is the precursor to the irregular C₁₂ terpenoid (4S, 4aS, 8aS)-1,2,3,4,4a,5,8,8a-octahydro-4,8a-dimethylnaphthalen-4a-ol (= dehydrogeosmin; 1 ). The irregular C-backbone originates from the oxidative removal of a C₃ side chain from a C₁₅ eudesmane-type intermediate (Scheme 2). The bicyclic C-framework is assembled by a formal addition of H₂O across the endocyclic double bonds of a monocyclic germacradiene-type precursor. The biosynthetic pathway follows from administration of the deuteriated farnesols 3b–e to flower heads of the cactaceae Rebutia marsoneri Werd. and mass-spectroscopic analysis of the collected volatiles.     

Subspace-Based Reduced-Order Modeling Methods for Structural Dynamic Systems

Computational costs for detailed Finite Element approximations can be reduced by using reduced-order models instead. In this contribution, four subspace-based reduced-order modeling methods are compared. (© 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
