The Vlasov-Poisson-Landau System in Rx3\R^3_x

For the Landau-Poisson system with Coulomb interaction in $\R^3_x$, we prove the global existence, uniqueness, and large time convergence rates to the Maxwellian equilibrium for solutions which start out sufficiently close.Comment: 50 page

The Georgia State University Copyright Case after the Appeal: Is It More Appealing?

The Georgia State University Copyright Case (Cambridge University Press v. Becker) and What It Means for Librarians

The Federal District Court in the Georgia State University copyright case (Cambridge University Press v Becker) constructed a carefully defined, but expansive Fair Use “safe harbor”. Academic libraries and not-for-profit educational institutions can use this “safe harbor” to make copies of copyright-protected materials and distribute them to students in a carefully controlled manner. The decision requires safeguards to help ensure that copies do not get disseminated beyond their intended audience. It also gives more flexibility in cases where publishers do not make smaller excerpts readily available. The Georgia State decision has been reported as allowing up to 10%,or a single chapter of a copyrighted work to be copied as “Fair Use”. This is an over-simplification of the court’s four factor “Fair Use” analysis. If one wishes to make wise, ethical decisions regarding the copying of copyrighted materials, one should have at least a general understanding of the four “Fair Use” factors and know how the court used them in the Georgia State case. The librarian community should also understand that this area of the law is still in a state of flux. This is the first case of its kind and the Publishers have appealed the decision, so it still could be modified on appeal. Other courts could also take a different approach. Still, this is a landmark case that has set a pattern that other courts are likely to follow or react against. The pattern set by this court is one that should allow librarians to act with greater confidence when making reasonable “Fair Use” decisions

Optimal time decay of the non cut-off Boltzmann equation in the whole space

In this paper we study the large-time behavior of perturbative classical solutions to the hard and soft potential Boltzmann equation without the angular cut-off assumption in the whole space \threed_x with \DgE. We use the existence theory of global in time nearby Maxwellian solutions from \cite{gsNonCutA,gsNonCut0}. It has been a longstanding open problem to determine the large time decay rates for the soft potential Boltzmann equation in the whole space, with or without the angular cut-off assumption \cite{MR677262,MR2847536}. For perturbative initial data, we prove that solutions converge to the global Maxwellian with the optimal large-time decay rate of O(t^{-\frac{\Ndim}{2}+\frac{\Ndim}{2r}}) in the L^2_\vel(L^r_x)-norm for any $2\leq r\leq \infty$.Comment: 31 pages, final version to appear in KR

Aeroelastic stability of wind turbine blade/aileron systems

Aeroelastic stability analyses have been performed for the MOD-5A blade/aileron system. Various configurations having different aileron torsional stiffness, mass unbalance, and control system damping have been investigated. The analysis was conducted using a code recently developed by the General Electric Company - AILSTAB. The code extracts eigenvalues for a three degree of freedom system, consisting of: (1) a blade flapwise mode; (2) a blade torsional mode; and (3) an aileron torsional mode. Mode shapes are supplied as input and the aileron can be specified over an arbitrary length of the blade span. Quasi-steady aerodynamic strip theory is used to compute aerodynamic derivatives of the wing-aileron combination as a function of spanwise position. Equations of motion are summarized herein. The program provides rotating blade stability boundaries for torsional divergence, classical flutter (bending/torsion) and wing/aileron flutter. It has been checked out against fixed-wing results published by Theodorsen and Garrick. The MOD-5A system is stable with respect to divergence and classical flutter for all practical rotor speeds. Aileron torsional stiffness must exceed a minimum critical value to prevent aileron flutter. The nominal control system stiffness greatly exceeds this minimum during normal operation. The basic system, however, is unstable for the case of a free (or floating) aileron. The instability can be removed either by the addition of torsional damping or mass-balancing the ailerons. The MOD-5A design was performed by the General Electric Company, Advanced Energy Program Department under Contract DEN3-153 with NASA Lewis Research Center and sponsored by the Department of Energy
