    No full text
    "Kitchen" is a 1988 novel by Japanese author Banana Yoshimoto. This novel enjoyed enormous popularity in the anglophone world (when it was published in English, in Megan Backus' 1993 translation), and is still very widely read. These 3 files include the beginning of the novel. Please print them out (or save them to your laptop/ tablet) so you can bring them to class when we start on Ideational Meanings

Massachusetts Institute of Technology.Georges Bank provides a basic and indispensable reference tool for anyone involved in studying the bank or in making decisions about its use. Until now debates about alternative uses of the bank have been hampered by the fact that much of the basic research has been available only to specialists and has been scattered among many publications. In bringing the available information on this complex region together for the first time, Georges Bank provides a basic and indispensable reference tool for anyone involved in studying the bank or in making decisions about its use. Moreover, the depth and clarity of the book's 57 articles and 8 nontechnical introductions will make it useful for anyone involved in oceanographic or ocean policy studies.Sections cover all aspects of this huge marine ecosystem - geology, weather and climate, physical oceanography, chemistry, phytoplankton, primary production, zoology and secondary production, the fisheries, and conflicting uses. Georges Bank is the first major project of the Coastal Research Center of Woods Hole Oceanographic Institution. The editor-in-chief, Richard H. Backus, is chairman of the Institutions's biology department. Includes 176 six-color maps, 54 four-color illustrations - 392 charts, graphs, and drawings

    Derivation and analysis of a computationally efficient discrete Backus-Gilbert footprint-matching algorithm

    No full text
    A computationally efficient discrete Backus-Gilbert (BG) method is derived that is subject to minimization constraints appropriate for footprint-matching applications. The method is flexible, since computational cost can be traded for accuracy. A comparison of the discrete BG method with a non-discrete BG method shows that the new method can be 250% more efficient while maintaining the same accuracy as traditional approaches. In addition, optimization approaches are used to further enhance the computational performance of the discretized BG method. A singular value decomposition approximation is applied that increases the computational efficiencies 43% to 106% while maintaining similar accuracies to the original discretized algorithm. Accuracies of the optimization were found to be scene dependent. In addition, alternative quadrature methods were also tested for several idealized simulated scenes. The results suggest that accuracy improvements could be made using customized quadrature methods that would be employed along known physical data discontinuities (such as along coastlines in microwave imagery data). In addition, regularization behaviors are also discussed; with a particular emphasis on the extension of the method for use with unnormalized gain functions. This work demonstrates that for some gain function configurations local biases can be intrinsic to the system. The flexibility of the discrete BG method allowed for several of the optimizations to be performed in a straightforward manner. Many additional optimizations are likely possible. Due to the lower computational cost of the method, this work is applicable toward applications in which noise may vary dynamically (such as in RFI-contaminated environments). The computational flexibility of the method also makes it well suited to computationally constrained problems such as 4D data assimilation of remote sensing observations.Research supported by the DoD Center for Geosciences/Atmospheric Research at CSU under Cooperative Agreement #DAAL01-98-0078 with the Army Research Laboratory
