We consider a minimum-entropy criterion to tackle some statistical signal and image processing problems. We focus on semiparametric models, with the aim to estimate a vector of unknown parameters, say θ⋆, of a given model in the presence of errors of unknown density. The lack of information on these errors is such that it is difficult to obtain both asymptotically efficient and robust procedure...

Of my own situation I wrote: “In one day I typically receive 5-10 pieces of regular junk mail, 15-25 regular letters, 5 pieces of campus mail, 5 reports or documents (not all technical), 5-10 incoming phone calls, 10-20 local electronic messages, and 10-20 external electronic messages. Although many of these messages are discarded or forwarded to others for handling, much of my time is required...

The problem of rotation corrections for hard mounted gravity gradiometers is widely regarded as intractable. In large part this is due to the unavailability of sufficiently accurate star sensors, gyros, and angular accelerometers. It will be shown here that, for floated satellite gradiometers, subject to very low levels of unmodeled forces and torques, dynamic estimation can dramatically reduce...

An aqueous solution was successfully prepared using a low-molecular-weight chitosan oligomer and FITC, and its structural and fluorescent properties were observed by using ¹H NMR, 13C NMR, FT-IR, XRD, UV-Vis, and PL spectrometry. Its application as a metal ion sensor was also evaluated. The fluorescence in the water-soluble chitosan oligomer was a result of the carbamato anion (NHCOO-), and a s...

The topic of morphological productivity as it has been conceived in linguistics for the last half-century is treated in greatest detail in Bauer (2001). If our brief discussion here leads the reader to that book, we will have gone a long way to doing our job. In this chapter, though, we also have a different aim, which is to recast the problem of morphological productivity in a different light....

This optimized two-point kinetic assay for serum angiotensin-converting enzyme is based on the colorimetric determination of hippurate with cyanuric chloride/dioxan reagent. The hippurate is released from hippuryl-L-histidyl-L-leucine by angiotensin-converting enzyme in the presence of chloride ion. CVs for the method (within-run and between-run) ranged from 2.1 to 3.2%. Linearity extends up to...
