Nanotechnology is one of the two major strategic research and education directions at Georgia Tech. We have over faculty who are actively engaging in various research in nanotechnology, including but not limited to, synthesis and properties of nanomaterials, novel techniques for nano-scale characterization, multi-length-scale modeling and simulation, nanoelectronics, catalysis, nanomedicine, nanodevices, and nanosystem integration and packaging.

It is generally believed that nanotechnology will touch every corner of our life, from health to write about self-dual polyhedral dice and to environment. This presentation will focus on what is nanotechnology, what is the fundamental science in nanotechnology, what are the challenges in developing nanotechnology, and what are the potential and impacts of nanotechnology.

Zhong Lin Wang received his Ph. His publications have been cited over times. He has received the S. His most recent research focuses on oxide nanobelts and nanowires, in-situ techniques for nano-scale measurements, self-assembly nanostructures, fabrication of nano devices, and properties of magnetic nanostructures.

Recent Results on Interval Graphs by Tom Trotter School of Mathematics, Georgia Tech in Skiles Interval graphs arise naturally as models for computer memory storage problems and in other settings where resources are allocated from a linear array.

Not surprisingly, interval graphs have been widely studied in graph theory and combinatorics. Here we discuss continuing progress on a problem which is now 30 years old: How well does the First Fit Algorithm Greedy do in coloring interval graphs. The presentation will include a discussion of why the problem is interesting, what has been done to date, what techniques have been developed and applied, and what is left to do.

Long ago, in my Dungeons & Dragons days, I was playing with polyhedral dice. I arranged 5 tetrahedrons around and edge and was contemplating the gap. I arranged 5 tetrahedrons around and edge and was contemplating the gap. Some polyhedra are self-dual, meaning that the dual of the polyhedron is congruent to the original polyhedron. [19] Abstract polyhedra also have duals, which satisfy in addition that they have the same Euler characteristic and orientability as the initial polyhedron. 1 Introduction Consider the following nonconvex quadratic optimization problem, which is referred to as the extended trust region problem: (P) min.

The method work in the multivariate setting. However, it yields a pre-Riesz basis for Sobolev space in the multivariate setting. Functional samples and bootstrap for predicting sulfur dioxide levels by Serge Guillas School of Mathematics, Georgia Tech in Skiles In this study, enhancements of several functional techniques are given in order to forecast sulfur dioxide levels near a power plant.

The data are considered as a time series of curves. Assuming a lag one dependence, the predictions are computed using the functional kernel with local bandwidth and the linear autoregressive Hilbertian model. We carry out the estimation with a so-called historical matrix, which is a subsample that emphasizes uncommon shapes.

Finally, we compare our functional techniques with neural networks and semi-parametric methods, and find that the former models are often more effective. Joint work with B. Fernandez de Castro and W. Approximations of short maps by PL-isometries by Svetlana Krat School of Mathematics, Georgia Tech in Skiles A PL-map between two polyhedral spaces is a continuous map which, for certain triangulation of the spaces maps every simplex from the first space to a simplex in the target space in a linear fashion.

It has been known due to V. A short map is a map that does not increase distances between points. An application of this result is a solution of one of V. We formalize this by asking if there exists a PL-isometry from the rectangle to a plane such that the perimeter of the image is greater than that of the rectangle.

These results were obtained in collaboration with D. In the Markov chain setting this involves finding the worst cutsets of a weighted graph.

We show a generalization in which cutsets for a range of set sizes can be used, not just the worst case. Our methods are sharp on several Markov chains, lead to bounds on the largest eigenvalue as well, and also bound rates of convergence for non-reversible Markov chains.

Such equations arise, for example, in the study of thin films, for which planar waves correspond with fluid coating a pre-wetted surface. An interesting feature of these equations is that both compressive and under compressive planar waves arise as solutions compressive or under compressive with respect to asymptotic behavior relative to the un-regularized hyperbolic systemand numerical investigation by Bertozzi, Munch, and Shearer indicates that under compressive waves can be nonlinearly stable.In the Drawn Together episode "Clara's Dirty Little Secret", Clara thinks she is pregnant, and Toot suggests that she fall down some stairs.

Clara thinks of a suitable room and leads them to the "M. C. Escher room", where Toot pushes Clara down (and up, around, and back down) a flight of stairs.

In Discover Magazine, the latest Jaron's World column talks about the cell, a four-dimensional self-dual abstract regular polytope. As a graph, it's K11, the complete graph on 11 vertices. As a graph, it's K11, the complete graph on 11 vertices.

The regular tetrahedron is self-dual, Especially in roleplaying, this solid is known as a 4-sided die, one of the more common polyhedral dice, with the number rolled appearing around the bottom or on the top vertex.

To change a decimal to a fraction, write in the denominator a 1 followed by as many zeroes as there are digits to the right of the decimal point, and write in the numerator all the digits in the original decimal, omitting the decimal point.

Cubical gaming dice in China have been dated back as early as B.C. [citation needed] which is a tessellation. The regular tetrahedron is self-dual, which means that its dual is another regular tetrahedron, the compound figure comprising two such dual tetrahedra form a stellated octahedron or stella octangula.
