We report optical photometry and Hi synthesis observations of the southern edge-on S c,d galaxy IC 5249. The observations were carried out primarily to determine if IC 5249 has a red halo surrounding it similar to the halo that has recently been found surrounding the northern edge-on galaxy NGC 5907. The galaxy IC 5249 is almost perfectly edge-on, and it shows no direct sign of warping or flari...

We report optical photometry and Hi synthesis observations of the southern edge-on Sc,d galaxy IC 5249. The observations were carried out primarily to determine if IC 5249 has a red halo surrounding it similar to the halo that has recently been found surrounding the northern edge-on galaxy NGC 5907. The galaxy IC 5249 is almost perfectly edge-on, and it shows no direct sign of warping or flarin...
We study the algorithmic problem of computing drawings graphs in which (i) each vertex is a disk with fixed radius ?, (ii) edge straight-line segment connecting centers two disks representing its end-vertices, (iii) no intersect, and (iv) distance between an center non-incident disk, called edge-vertex resolution, at least ?. call such disk-link drawings.
Two problems in the search of metric characteristics on weighted undirected graphs with non-negative edge weights are being considered. The first problem: a weighted undirected graph with non-negative edge weight is given. The radius, diameter and at least one center and one pair of peripheral vertices of the graph are to be found. In the second problem we have additionally calculated the dista...
Common quality metrics of graph drawing have been about the readability criteria, such as small number of edge crossings, small drawing area and small total edge length. Bold graph drawing considers more realistic drawings consisting of vertices as disks of some radius and edges as rectangles of some width. However, the relationship that links these readability criteria with the rendering crite...
The regularized D-bar method for electrical impedance tomography (EIT) provides a rigorous mathematical approach for solving the full nonlinear inverse problem directly, i.e., without iterations. It is based on a low-pass filtering in the (nonlinear) frequency domain. However, the resulting D-bar reconstructions are inherently smoothed, leading to a loss of edge distinction. In this paper, a no...
The flux-corrected transport (FCT) methodology is generalized to implicit finite element schemes and applied to the Euler equations of gas dynamics. The underlying low-order scheme is constructed by applying scalar artificial viscosity proportional to the spectral radius of the cumulative Roe matrix. All conservative matrix manipulations are performed edge-by-edge which leads to an efficient al...
Hemming is a three-step sheet-folding process utilized in the production of automotive closures. It has a critical impact on the performance and perceived quality of assembled vehicles. Using a two-dimensional finite element model, this paper presents a design-of-experiments (DOE) study of the relationships between important hemming process parameters and hem quality for aluminium alloy AA 6111...
