    This article presents recent progress in understanding solar wind-Mars interaction using a sophisticated global magnetohydrodynamic (MHD) model. Mars has localized crustal magnetic fields, so the solar wind plasma flow interacts directly with the Mars atmosphere/ionosphere system. Such an interaction generates an induced current in the ionosphere, modifies the magnetic field environment around Mar... View full abstract»

  • Trajectory Optimization for Missions to Small Bodies with a Focus on Scientific Merit

    Trajectory design for missions to small bodies is tightly coupled both with the selection of targets for the mission and with the choice of spacecraft power, propulsion, and other hardware. Traditional methods of trajectory optimization have focused on finding the optimal trajectory for an a priori selection of destinations and spacecraft parameters. Recent research has expanded the field to multi... View full abstract»

    Semisupervised DR techniques using virtual label regression have attracted considerable attention, but they suffer from two restrictions: the number of discriminant directions available is constrained to the number of classes, and they're nonorthogonal. Traditional methods easily address these problems. However, an interesting problem is how to address these restrictions in label regression modeli... View full abstract»

    Completing a full replication study of the authors' previously published findings on bluff-body aerodynamics was harder than they thought, despite them having good reproducible-research practices, such as sharing their code and data openly. Here's what they learned from three years, four computational fluid dynamics codes, and hundreds of runs. View full abstract»

    This article proposes a 4D segmentation method by considering the 3D t data as a 4D hyper object, using a D4Q81 lattice in a lattice Bhatnagar-Gross-Krook (LBGK) simulation, where time is considered a fourth dimension for defining directions of particle momentum in the LBGK model. They implemented 4D-LBGK on 20 4D hypersphere and hypercube images with varying amounts of Gaussian noise added (0-300... View full abstract»

    Two recent projects have used the Cray XK7 Titan supercomputer at the US Department of Energy's Oak Ridge National Laboratory to study Earth's dynamics, specifically seismology-related studies. Using Titan, one team of researchers modeled Earth's interior using earthquake data, while a second team developed physics-based earthquake simulations for disaster management applications. Together, the pr... View full abstract»

    A decade of discourse to capture the essence of computational thinking has resulted in a broad set of skills whose teaching continue to pose challenges because of the reliance on the use of electronic computers and programming concepts. This article not only links computational thinking skills to fundamental cognitive competencies but also describes pedagogical tools that have proven effective in ... View full abstract»

    The ISO/IEC Fortran standards working group states that the third most detectable type of error in scientific software is “incorrect use of units of measurement” and has developed a draft specification for incorporating unit-checking into Fortran compilers. This article shows that unit-checking is insufficient to detect all quantity errors, and that kind-of-quantity also needs to be ... View full abstract»
