As traffic volumes increase on major intersecting arterials, the transportation engineer’s challenge is one of optimizing through traffic while providing adequate opportunities for leftturning vehicles. Increasing traffic volumes not only provide a proportionately higher number of leftturning vehicles, but also make it more difficult to negotiate a left turn due to increased opposing traffic. T...
The development of endocavitary dual-mode probes is essential for the accurate treatment of many deep seated cancers which require a high imaging resolution and the capacity to selectively treat focal areas in the region of interest. The MULTIP project is aimed at using state-of-art piezoelectric technologies to design dual-mode ultrasonic probes for cancer-foci treatment and monitoring. In ord...
The effects of dual consistency on discontinuous Galerkin (DG) discretizations of solution and solution gradient dependent source terms are examined. Two common discretizations are analyzed: the standard weighting technique for source terms and the mixed formulation. It is shown that if the source term depends on the first derivative of the solution, the standard weighting technique leads to a ...
The Colin de Verdière number μ(G) of a graph G is the maximum corank of a Colin de Verdière matrix for G (that is, of a Schrödinger operator on G with a single negative eigenvalue). In 2001, Lovász gave a construction that associated to every convex 3-polytope a Colin de Verdière matrix of corank 3 for its 1-skeleton. We generalize the Lovász construction to higher dimensions by interpreting it...
We address the description of tropicalization families rational varieties under parametrizations with prescribed support, via curve valuations. recover and extend results by Sturmfels, Tevelev Yu for generic coefficients, considering non-trivial denominator. The advantage our point view is that it can be generalized to deal non-generic parametrizations. provide a detailed analysis degree closed...
