The purpose of this research was to evaluate the nonlinear dynamic response of rigid and semi-rigid steel frames under Far-Fault Earthquake Records. Accordingly, the fragility curve of the moment frames with rigid and semi-rigid connections was determined. Considering the analytical knowledge of structures in the past, the analysis and design of steel frames based on the assumptions of rigid or...

We investigate the molecular structure information contained in the x-ray diffraction patterns of an ensemble of rigid CF(3)Br molecules aligned by an intense laser pulse at finite rotational temperature. The diffraction patterns are calculated at an x-ray photon energy of 20 keV to probe molecular structure at angstrom-scale resolution. We find that a structural reconstruction algorithm based ...

Four enhancements have been devised, both on a semantic and efficiency level, that improve existing methods of automated criminal career analysis. A new distance measure was introduced that more closely resembles the reality of policing. Instead of previous, more rigid, comparison of career changes over time we propose an alignment of these careers. We employ a faster and better method to clust...

This paper presents a unified variational framework for seamlessly integrating prior segmentation information into non-rigid registration procedures. Under this framework, in addition to the forces arise from the similarity measure in seeking for detailed correspondence, another set of forces generated by the prior segmentation contours can provide an extra guidance in assisting the alignment p...

Comparison of different object instances is hard due to the large intra-class variability. Part of this variability is due to viewpoint and pose, another due to subcategories and texture. The variability due to mild viewpoint changes, can be normalized out by aligning the samples. In contrast to the classical Procrustes distance, we propose distances based on non-rigid alignment and show that t...

This work reports theoretical studies on the occurrence oi a static periodic distortion (PD in a nematic sample under the action of crossed electric (E) and magnetic (H) fields applied on a uniformly aligned initial director configuration (no) Linear stability analysis with rigid anchoring hypothesis is employed For homeotropic alignment of a nematic such as &f1 which has negative dielectric an...

2014 If linear micelles are considered to be rigid, their growth couples so strongly to alignment in the nematic phase that they grow almost without bound but we show that this coupling is greatly diminished when a realistic flexibility is taken into account. Analytical expressions for the coexistence variables are derived for the complete range of semiflexibility. Enhancement of growth by modi...

This work introduces a 3D+t coronary registration strategy to minimize the navigation among cardiac phases during the process of ischaemic heart disease diagnosis. We propose to register image subvolumes containing suspected arterial lesions at two cardiac phases, instead of performing a registration of the complete cardiac volume through the whole cardiac cycle. The method rst automatically de...
