Structural elucidation of a common architecture of the nuclear pore complex and COPIl vesicle coats
… ancestor. Sec3l ACE1 units interact to form edge elements in the COPI lattice. Using structural knowledge of this edge element, we identified corresponding interactions between ACE1 proteins Nup84 and Nup145C in the NPC. We solved the crystal structure of the heterotrimeric Nup84-Nupl …

Numerical and experimental modelling of microwave applicators
… types of element are considered; nodal, Whitney edge elements and linear edge elements. Comparisons of the errors with these elements show that Whitney elements produce a consistently lower error when post-processing is used to smooth the solution. The coupled thermal-electromagnetic problem is …

An enhanced volume integral equation method and augmented equivalence principle algorithm for low frequency problems
… and permeability terms. Curl-conforming edge elements are used to model the electric field distributions. Integration by parts is applied to deal with the singularities at the boundary introduced by the discontinuities of the material properties. Duffy's method formulations are derived …

Human Movement Analysis: Ballistic Dynamics, and Edge Continuity for Pose Estimation
… movements, and (b) a model for coupling edge continuity with contour matching. We describe a Bayesian approach for visual analysis of ballistic hand movements, namely reaches and strikes. These movements are most commonly used for interacting with objects and the environment. One of the …

Structural studies of large architectural nucleoporins and coat proteins
… and Nup84-Nup145C-Sec13 complexes form analogous edge elements for the COPII coat and the NPC. A sequence-based search for other ACE1s identified the COPII accessory protein Sec16. Sec16 and Sec13 were shown to form a 2:2 heterotetramer. A crystal structure of Sec13-Sec16 revealed similarities to …

Modelling and analysis of complex electromagnetic problems using FDTD subgridding in hybrid computational methods. Development of hybridised Method of Moments, Finite-Difference Time-Domain method and subgridded Finite-Difference Time-Domain method for precise computation of electromagnetic interaction with arbitrarily complex geometries
… circumvent this difficulty. The establishment of edge elements has greatly improved the performance of this method and the computational burden due to huge numbers of time steps, in the order of tens of millions, has been eased to tens of thousands by employing quasi-static methods. This thesis …

Near field coupling between elements of a finite planar array of circular apertures
… that in some cases, the diffractions from the edges of the ground plane caused some appreciable variations in the measured data, although the measurements in all cases tended to scatter about the calculated values. A numerical study was performed in order to determine the effect of higher order …

Conservation and efficiency in least squares finite element methods
… methods for high-order H(curl) conforming finite elements. Such elements are often used in mimetic discretizations of Maxwell's equations often solved in electromagnetic applications. Efficient multigrid methods for high-order H^1 conforming finite elements and also for the lowest-order H(curl) …

Efficient Finite Element Electromagnetic Analysis for High-Frequency/High-Speed Circuits And Multiconductor Transmission Lines
… field solver with high-order vector elements for high-frequency and high-speed circuit simulations. The solver supports wave port and lumped port excitations as well as the incorporation of lumped networks and circuit models in a distributed finite element model. An adaptive …
