Accident investigation

The National Transportation Safety Board (NTSB) has attributed wind shear as a cause or contributing factor in 15 accidents involving transport-categroy airplanes since 1970. Nine of these were nonfatal; but the other six accounted for 440 lives. Five of the fatal accidents and seven of the nonfatal accidents involved encounters with convective downbursts or microbursts. Of other accidents, two which were nonfatal were encounters with a frontal system shear, and one which was fatal was the result of a terrain induced wind shear. These accidents are discussed with reference to helping the aircraft to avoid the wind shear or if impossible to help the pilot to get through the wind shear

Savannah River Basin Comprehensive Water Resources Management Study

Proceedings of the 2001 Georgia Water Resources Conference, April 26 and 27, 2001, Athens, Georgia.A comprehensive water resources management study has been authorized by the 1996 Water Resources Development Act (WRDA) directing the U.S. Army Corps of Engineers to develop an updated plan addressing current and future needs in the basin, examine reallocation of storage, and to develop a better management structure to deal with basin water resources issues. The Reconnaissance Phase and development of a scope of work for the feasibility phase was completed in July and September of 1999, respectively. A Feasibility Study Cost-Sharing Agreement, defining a partnership with the states of Georgia and South Carolina, was signed in June 2000. Under this agreement, the feasibility phase is cost-shared 50% Federal funds and 50% combined state funds. Currently, as the states secure their cost shares, the Corps-Georgia-South Carolina team has been defining the overall study make-up, and initiating the first study actions.Sponsored and Organized by: U.S. Geological Survey, Georgia Department of Natural Resources, Natural Resources Conservation Service, The University of Georgia, Georgia State University, Georgia Institute of TechnologyThis book was published by the Institute of Ecology, The University of Georgia, Athens, Georgia 30602-2202.

The role of complex structures in w-symmetry

In a symplectic framework, the infinitesimal action of symplectomorphisms together with suitable reparametrizations of the two dimensional complex base space generate some type of W-algebras. It turns out that complex structures parametrized by Beltrami differentials play an important role in this context. The construction parallels very closely two dimensional Lagrangian conformal models where Beltrami differentials are fundamental.Comment: LaTex, 34 pages, no figures, to be published in Nucl. Phys.
