In the first person and in the house : The house chronotope in four works by American women writers
- 1999
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The house looms large in American literature and plays a significant part in American society and history. This study uses Mikhail Bakhtin's concept of the chronotope to examine the house in Harriet Jacobs's Incidents in the Life of a Slave Girl (1861), Elizabeth Stoddard's The Morgesons (1862), Octavia Butler's Kindred (1979), and Marilynne Robinson's Housekeeping (1980). All four texts were written by American women and have female narrator-protagonists.At a time when it has been widely acknowledged that universals and binary oppositions have serious critical and political limitations, there is a need for approaches that can bring together multiple issues in criticism. This study proposes that the chronotope, which operates on several intra- and intertextual levels, offers such an approach. Employing the house chronotope as a focal point, I find it possible to probe the connections and tensions in the four works between time and space, generic concerns, ideology, first-person narration, and identity formation based on constructions of gender, race, class, sexuality, and nationality.The study furthermore investigates the interplay between the house chronotope and the chronotope of the town and also suggests that one may see Sylvie in Housekeeping as representing a chronotope of her own. Moreover, I address the question of the literary house chronotope's stability over time as indicated in these four works by four American women writers.

Model-based and matched-filterbank signal analysis
- 1999
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The dissertation deals with model-based and matched-filterbank signal analysis. The matched-filterbank (MAFI) spectral estimation approach is introduced, and it is shown that both the amplitude spectrum Capon (ASC) and the amplitude and phase estimation (APES) spectral estimators can be expressed as MAFI spectral estimators. A combined estimation procedure for data with mixed spectrum is introduced, as well as ASC and APES implementations for real-valued data. Computationally efficient implementations of the 2-D power spectrum Capon (PSC) and the 1-D and 2-D ASC are proposed. An asymptotic Cramér-Rao bound for line-spectra estimation is derived. It is shown that the non-linear least squares method (NLSM) will asymptotically achieve the same statistical performance as the maximum likelihood method (MLM) even in the colored noise case. Sufficient conditions for identifiability are derived for known and unknown waveforms received through a multipath channel. Statistically efficient subspace-based estimators for the estimation of the time-delay and Doppler parameters are presented.
