Strong isolation by distance among local populations of an endangered butterfly species (Euphydryas aurinia) [PDF]
The marsh fritillary (Euphydryas aurinia) is a critically endangered butterfly species in Denmark known to be particularly vulnerable to habitat fragmentation due to its poor dispersal capacity.

Prediction and reduction in vehicle noise by frequency response function–based substructuring
The purpose of this study was to use a hybrid frequency response function–based substructuring synthesis method to predict the structure-borne noise of a vehicle frame resulting due to excitation by the engine and to develop a noise reduction method for ...

Abstract The CKM matrix is not generic. The Wolfenstein parametrization encodes structure by having one small parameter, λ ≈ 0.22. We pose the question: is there substructure in the CKM matrix that goes beyond the single small parameter of the Wolfenstein parameterization?

Configuration-Dependent Substructuring as a Tool to Predict the Vibrational Response of Mechanisms
Dynamic substructuring allows us to predict the dynamic behavior of mechanical systems built by linking together several subsystems, whose dynamic behavior is known.

On symmetries of substructures [PDF]
This paper accompanies a lecture given at the 2003 CCP4 Study Weekend on experimental phasing. With the audience of the CCP4 Study Weekend in mind, an overview is given of symmetries of substructures and the implications for single isomorphous replacement and single anomalous diffraction phasing procedures, as well as difference Fourier analyses ...

Modal contribution index of subsystems for studying vibration countermeasures of a whole structure
When designing NVH (Noise, Vibration and Harshness) performance for complex structures such as automobiles, trains, and aircraft, it is rare to target all components of the whole structure and the subsystem be designed are often fixed.

Reducing Computational and Memory Cost of Substructuring Technique in Finite Element Models [PDF]
Substructuring in the finite element method is a technique that reduces computational cost and memory usage for analysis of complex structures. The efficiency of this technique depends on the number of substructures in different problems.
