Books about Split level from Amazon.com

The thousands of devoted readers who follow the weekly chronicles of Bechdel's cartoon heroines--Lois, Sparrow, Ginger, Jezanna, and Mo, among others--probably already know that the strips read best in book form, where Bechdel's sly observations of lesbian life in the 1990s can blend with her ongoing narrative into something like a sketchy but provocative novel. Split-Level Dykes, the eighth collection in the series, is no exception. Its two dominant story lines--politically correct Mo commits herself to the brainy and self-absorbed Sydney, while Clarice and Toni, lesbian moms of color, nearly break up over their move to the great white suburbs--keep the reader enthralled and anxious, easy prey to the comic relief of Sparrow's heterosexual panic and the dating foibles of the swashbuckling Lois. With an anthropologist's eye for social detail, Bechdel fleshes out her two-dimensional world into something you could consider either the best kind of beach reading or the stuff of doctoral dissertations. --Regina Marler.

This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A379483. The abstract provided by the Pentagon follows: This thesis develops an extended Kalman filter for real-time estimation of rigid body motion altitude. The filter represents rotations using quaternions rather than Euler angles, which eliminates the long-standing problem of singularities associated with those angles. A process model for rigid body angular motions and angular rate measurements is defined. The process model converts angular rates into quaternion rates, which are in turn integrated to obtain quaternions. The outputs of the model are values of three-dimensional angular rates, three-dimensional linear accelerations, and three-dimensional magnetic field vector. Gauss-Newton iteration is utilized to find the best quaternion that relates the measured linear accelerations and earth magnetic field in the body coordinate frame to calculated values in the earth coordinate frame. The quaternion obtained from the optimization algorithm is used as part of the observations for the Kalman filter. As a result, the measurement equations become linear. A new approach to attitude estimation is introduced in this thesis. The computational requirements related to the extended Kalman filter developed using this approach are significantly reduced, making it possible to estimate attitude in real-time. Extensive static and dynamic simulation of the filter using Matlab proved it to be robust. Test cases included the presence of large initial errors as well as high noise levels. In all cases the filter was able to converge and accurately track attitude..
