HI in the Outskirts of Nearby Galaxies

The HI in disk galaxies frequently extends beyond the optical image, and can trace the dark matter there. I briefly highlight the history of high spatial resolution HI imaging, the contribution it made to the dark matter problem, and the current tension between several dynamical methods to break the disk-halo degeneracy. I then turn to the flaring problem, which could in principle probe the shape of the dark halo. Instead, however, a lot of attention is now devoted to understanding the role of gas accretion via galactic fountains. The current $\rm \Lambda$ cold dark matter theory has problems on galactic scales, such as the core-cusp problem, which can be addressed with HI observations of dwarf galaxies. For a similar range in rotation velocities, galaxies of type Sd have thin disks, while those of type Im are much thicker. After a few comments on modified Newtonian dynamics and on irregular galaxies, I close with statistics on the HI extent of galaxies.Comment: 38 pages, 17 figures, invited review, book chapter in "Outskirts of Galaxies", Eds.

Classics at Berkeley: The First Century 1869-1970

During retirement, the late Joseph Fontenrose (1903-1986) conducted research in the departmental and university archives to compile this account of the Department of Classics at the University of California, Berkeley (and its predecessor departments) during the first hundred years of the university. It contains biographies and bibliographies of the long-term professors and lists of other teachers, and also tells of the development of the curriculum in different periods.The book was privately published with the support of the Department of Classics History Fund, and a few printed copies are still to be seen in the Department.This digital edition was prepared in June 2007

Robust MIMO control systems design using eigen-structure assignment and QFT

An approach to robust control design for a multi-input/multi-output (MIMO) plant using eigenstructure assignment (EA) and quantitative feedback theory (QFT) is presented and applied to the design of a lateral flight control system. EA techniques are introduced to give an initial feedback control design for the nominal plant model, providing decoupling between the multiple control channels. The QFT method for single-input/single-output (SISO) plants is used to obtain robust stability under the given plant-parameter uncertainties. Detailed designs are conducted with both the proposed EA/QFT approach and the direct MIMO QFT approach. The design results demonstrate the good performance and features of the proposed EA/QFT approach that may be achieved
