2006 OCEANS 2006  
This presentation provides an overview of multimedia learning materials produced by the COMET® Program for civilian and military operational meteorologists, university students, and others interested in marine science. There are several project teams developing learning materials on different aspects of marine science. The NPOESS Integrated Program Office sponsors a team dedicated to highlighting current and future polar-orbiting satellite capabilities. Currently, the team is developing a

Other COMET teams, sponsored by the National Weather Service, are developing modules several topics in marine meteorology. All of the modules integrate carefully designed, scientifically accurate animations and models addressing crucial scientific concepts related to module objectives. The presentation will include an overview of the COMET Program and the NPOESS/IPO efforts, along with examples from several modules from the NPOESS and marine meteorology series. 14. ABSTRACT 15.

Differential Geometry Revisited by Biquaternion Clifford Algebra [chapter]

Patrick R. Girard, Patrick Clarysse, Romaric Pujol, Liang Wang, Philippe Delachartre
2015 Lecture Notes in Computer Science  
In the last century, differential geometry has been expressed within various calculi: vectors, tensors, spinors, exterior differential forms and recently Clifford algebras. Clifford algebras yield an excellent representation of the rotation group and of the Lorentz group which are the cornerstones of the theory of moving frames. Though Clifford algebras are all related to quaternions via the Clifford theorem, a biquaternion formulation of differential geometry does not seem to have been

The formalism being new, the approach is intended to be pedagogical. Since the methods of Clifford algebras are similar in other dimensions, it is hoped that the paper might open new perspectives for a 4D hyperbolic differential geometry. All the calculi presented here can easily be implemented algebraically on Mathematica and numerically on Matlab. Examples, matrix representations, and a Mathematica work-sheet are provided.

Ultrafast ion sieving using nanoporous polymeric membranes

Pengfei Wang, Mao Wang, Feng Liu, Siyuan Ding, Xue Wang, Guanghua Du, Jie Liu, Pavel Apel, Patrick Kluth, Christina Trautmann, Yugang Wang
2018 Nature Communications  
The great potential of nanoporous membranes for water filtration and chemical separation has been challenged by the trade-off between selectivity and permeability. Here we report on nanoporous polymer membranes with an excellent balance between selectivity and permeability of ions. Our membranes are fabricated by irradiating 2-μm-thick polyethylene terephthalate Lumirror® films with GeV heavy ions followed by ultraviolet exposure. These membranes show a high transport rate of K + ions of up to

Combining transport experiments and molecular dynamics simulations with a polymeric nanopore model, we demonstrate that the high permeability is attributable to the presence of nanopores with a radius of~0.5 nm and a density of up to 5 × 10 10 cm −2 , and the selectivity is ascribed to the interaction between the partially dehydrated ions and the negatively charged nanopore wall.

Low-Carbon Cities: Lifestyle Changes Are Necessary

Patrick Moriarty, Stephen Wang
2015 Zenodo  
Today, more than half the world's population live in cities, and the UN expect this figure to rise to two-thirds by 2050. Already, cities are responsible for an estimated 70% of global energy use. Cities must cut their energy use in order to reduce greenhouse gas emissions, the Urban Heat Island effect and urban air pollution, and global fossil fuel (especially oil) depletion. Available approaches include shifting to alternative energy, energy efficiency improvements, and energy conservation.

This is important because many researchers argue that large reductions in oil, and to a lesser extent other fossil fuels, will be needed within the next two decades, because of their mounting energy, monetary and environmental costs. Achieving the necessary large cuts in both fossil energy use and their accompanying emissions will, we argue, necessitate energy conservation, largely though lifestyle changes.

Anomalous magnetohydrodynamics with constant anisotropic electric conductivities [article]

Ren-jie Wang, Patrick Copinger, Shi Pu
2020 arXiv   pre-print
We study anomalous magnetohydrodynamics in a longitudinal boost invariant Bjorken flow with constant anisotropic electric conductivities as outlined in Ref. [1]. For simplicity, we consider a neutral fluid and a force-free magnetic field in the transverse direction. We derived analytic solutions of the electromagnetic fields in the laboratory frame, the chiral density, and the energy density as functions of proper time.

Reflections in art

Patrick Cavanagh, Dina Wang, Jessica Chao
2008 Spatial Vision  
When artists depict a mirror in a painting, it necessarily lacks the most obvious property of a mirror: as we move around the painting of the mirror, the reflections we see in it do not change. And yet representations of mirrors and other reflecting surfaces can be quite convincing in paintings. Here, we will examine the rules of reflection, the many ways that painters can break those rules without losing the impression of reflection and the rules that cannot be broken. The rules that govern

Using asynchronous simulation approach for interactive simulation [article]

Mengchen Wang, Nicolas Ferey, Patrick Bourdot, Frederic Magoules
2019 arXiv   pre-print
This paper discusses about the advantage of using asynchronous simulation in the case of interactive simulation in which user can steer and control parameters during a simulation in progress. synchronous models allow to compute each iteration faster to address the issues of performance needed in an highly interactive context, and our hypothesis is that get partial results faster is better than getting synchronized and final results to take a decision, in a interactive simulation context.
