We study the effect of the uncertainty of wind power on the angular stability of power systems, including a single-machine, infinite-bus (SMIB) system, and a three-generator, nine-bus multi-machine system, which are subject to a self-clearing three-phase fault. Probability density function (PDF) and Monte Carlo (MC) methods are used to calculate...

In porous media, the motion of charges at the fluid/solid interfaces induces a coupling between seismic and electromagnetic waves. This phenomenon, known as the electro-kinetic effect is at the heart of electroseismic imaging, a technique used in oil prospection to image sedimentary layers of porous media. It combines the high sensitivity to mat...

We consider distributed control in two distinct network applications: sponsored search and switched networks.First, we consider a large-scale sponsored search market. For this pay-per-click market, we discuss an efficient and highly decomposed mechanism that maximizes social welfare. Here on each search occurrence, the search-platform solves an ...

Two elementary Ricker maps in the positive half-line are coupled to produce a planar mapping leaving the positive cone invariant. While this mapping appears to provide an exercise fit for a Calculus class, it is one of the most challenging problems ever experienced by the authors, namely to prove global attraction to the interior fixed point, al...

The critical power for collapse appears to place an upper bound on the amount of power that can be propagated by intense laser beams. In various applications, however, it is desirable exceed this limit and deliver more power. In this talk I will present new solitary waves of the two-dimensional nonlinear Schrodinger equation on bounded domains, ...

I will present some results on the existence andnonlinear stability for the rotating star solutions which areaxi-symmetric steady-state solutions of the compressibleisentropic Euler-Poisson equations in 3 spatial dimensions.We then apply these results to rotating white dwarf stars toshow its dynamical stability when the totalmass is less than a ...

The North American electric power grid is a large existing distributed network that will present new stability and control problems should the penetration of distributed renewable sources, controllable loads, and local-area energy storage capabilities become a significant portion of the overall grid. Roof-top solar panels and small wind turbines...

In this talk, I'd like to discuss the intertwining importance and connections of three principles of data science in the title in data-driven decisions. The ultimate importance of prediction lies in the fact that future holds the unique and possibly the only purpose of all human activities, in business, education, research, and government alike....

The current talk is concerned with transition fronts of nonlocal dispersal evolution equations in heterogeneous media. As it is known, solutions of nonlocal dispersal evolution equations do not become smoother in space as time elapses. This lack of space regularity would cause a lot of difficulties in studying transition fronts in nonlocal dispe...
