Mathews, V. John | Adaptive phase transform processors for time delay estimation | This paper introduces two recursive realizations of the phase transform (PHAT) processor for time-delay estimation (TDE), using a simple one-pole low-pass filter and the least-mean-square (LMS) adaptive filter, respectively.

Mathews, V. John | Adaptive realization of a maximum likelihood time delay estimator | ABSTRACT This paper presents an adaptive maximum likelihood method for estimating the time difference of arrival of a source signal at two spatially separate sensors. It is well-known that the maximum likelihood technique achieves the Cramer-Rao lower bound for time delay estimation error for ce... | | 1996 |

Mathews, V. John | Adaptive unsharp masking for contrast enhancement | ABSTRACT A new scheme o,f unsharp masking for image contrast enhancement is presented in this paper. An adaptive algorithm is introduced so that a sharpening action is performed only in locations where the image exhibits significant dynamics. Hence, the amplification of noise in smooth areas i... | | 1997 |

Andreou, Chrisoula | Addiction, procrastination, and failure points in decision-making systems | Redish et al. suggest that their failures-in-decision-making framework for understanding addiction can also contribute to improving our understanding of a variety of psychiatric disorders. In the spirit of reflecting on the significance and scope of their research, I briefly develop the idea that t... | Addiction; Failure in decision-making systems | 2008-08 |

McDaniel, Susan | Adoption in Canada: A neglected area of data collection and research | For some decades there has been in Canada, as in the United States, recurrent public interest in adoption. At various times this interest has been kindled by professional concern about unauthorized child placement and by the plight of children made homeless by war and other calamities. More recently... | Canada; Adoption; Statistics | 1981 |
