    On stability of interval matrices
    (Institute of Electrical and Electronics Engineers, 1994-02) Sezer, M. E.; Siljak, D. D.
    New sufficient, and sometimes necessary and sufficient conditions, are obtained for Schur- and Hurwitz-stability of interval matrices by relying on the concept of connective stability and M-matrices. The necessity part is broadened to include interval matrices with mixed signs of the off-diagonal elements, provided the sign patterns follow that of the Morishima matrix. The obtained results are extended to cover convex combinations of interval matrices.

    Personal navigation via high-resolution gait-corrected inertial measurement units
    (IEEE, 2010) Bebek O.; Suster, M.A.; Rajgopal, S.; Fu, M.J.; Huang X.; Çavuşoğlu, M. Cenk; Young, D.J.; Mehregany, M.; Van Den Bogert, A.J.; Mastrangelo, C.H.
    In this paper, a personal micronavigation system that uses high-resolution gait-corrected inertial measurement units is presented. The goal of this paper is to develop a navigation system that uses secondary inertial variables, such as velocity, to enable long-term precise navigation in the absence of Global Positioning System (GPS) and beacon signals. In this scheme, measured zero-velocity duration from the ground reaction sensors is used to reset the accumulated integration errors from accelerometers and gyroscopes in position calculation. With the described system, an average position error of 4 m is achieved at the end of half-hour walks. © 2010 IEEE.
