This paper presents an overview of the National Advanced Driving Simulator (NADS), its design, and core capabilities. The NADS is a high-fidelity driving simulator whose goal is to investigate human-centered issues as they relate to driving safety. Its primary mission is to investigate causes of accidents, with the goal of reducing fatalities on U.S.(More)
The expansion of the Panama Canal could be the largest project attempted by the Republic of Panama in its 100 years of existence. The objective of this simulation study is to use the Canal Expansion project to develop and demonstrate how more precise and applied concepts involving the complex decision making processes can be used in large "system of(More)
Recent developments in numerical methods for high speed vehicle dynamic simulation in the multi-university Automotive Research Center sponsored by the U.S. Army Tank-Automotive Research, Development, and Engineering Center are summarized and illustrated. The prior state-of-the-art is reviewed and computational developments focusing on both computer-aided(More)
The present work digs into some of the accuracy issues the authors have found when dealing with plasmonic problems in the vicinity of quasi-statics, where the dimension of the particles inevitably leads to extremely small mesh sizes to preserve the geometrical features. Obviously, these problems can always be traced back to a certain lack of precision in(More)
The present work focuses on the electromagnetic simulation of densely-packed crystalline assemblies of subwavelength particles (metamaterials), for which a rigorous full-wave analysis still remains challenging. Indeed, even for moderate electric sizes, the overly-populated mesh needed to preserve the geometrical features of this kind of structures leads to(More)
The frontiers in the research field of nanoplasmonics are not seldom restrained by the limits imposed by available electromagnetic analysis tools, which tend to struggle when addressing realistic systems with several-wavelength electric sizes. This work shows that boundary element variational methods, along with the hierarchical spectral compression of the(More)
Optical connections will become a key point in the next generation of integrated circuits, namely the outcoming nano-scale optical chips. In this context, nano-optical wireless links using nanoantennas have been presented as a promising alternative to regular plasmonic waveguide links, whose main limitation is the range propagation due to the metal(More)
Surface Integral Equations (SIEs) constitute a very powerful method for the analysis of electromagnetic scattering of homogeneous penetrable objects. The discretization of SIEs, however, results in a non-sparse system matrix, expensive to store and solve. In order to consider complex large-scale problems with a high number of unknowns, acceleration methods(More)
Numerical computations using surface integral equation formulations solved by the method of moments are carried out in order to demonstrate that these techniques are useful tools for optical nanoantennas design. It is shown that almost frequency independent directivity patterns can be obtained over a large bandwidth for judiciously designed log-periodic(More)
Surface-integral-equation (SIE) approaches are presented for the accurate solution of different problems in computational electromagnetics. First, an efficient message passing interface (MPI)/OpenMP parallel implementation of the multilevel fast multipole algorithm-fast Fourier transform (MLFMA-FFT) is presented for the solution of large-scale conducting(More)
