TL;DR: The dynamical mean-field method is used to study a model of electrons Jahn-Teller coupled to localized classical oscillators and ferromagnetically coupled to core spins that contains the essential physics of theossal magnetoresistance of manganites.
Abstract: We use the dynamical mean-field method to study a model of electrons Jahn-Teller coupled to localized classical oscillators and ferromagnetically coupled to {open_quote}{open_quote}core spins.{close_quote}{close_quote} The model, we argue, contains the essential physics of the {open_quote}{open_quote}colossal magnetoresistance{close_quote}{close_quote} manganites Re{sub 1{minus}{ital x}}{ital A}{sub {ital x}}MnO{sub 3}. We determine the different regimes of the model and present results for the temperature and frequency dependence of the conductivity, the electron spectral function, and the root-mean-square lattice parameter fluctuations. We compare our results to data and give a qualitative discussion of important physics not included in the calculation. Extensive use is made of results from a companion paper [Phys. Rev. B {bold 54}, 5389 (1996)]. {copyright} {ital 1996 The American Physical Society.}

TL;DR: It is shown that this measure is not appropriate and a modified form that meets, in an optimal way, the needs for an efficient DTD is proposed that is also a definition of the normalized cross-correlation matrix between two vectors and a link with the coherence function.
Abstract: A doubletalk detector (DTD) is used with an echo canceler to sense when far-end speech is corrupted by near-end speech. Its role is to freeze the adaptation of the model filter when near-end speech is present in order to avoid divergence of the adaptive algorithm. Several authors have proposed to use the cross-correlation coefficient vector between the input signal vector x and the scalar output y for a DTD. We show in this paper that this measure is not appropriate and propose a modified form that meets, in an optimal way, the needs for an efficient DTD. By extension, we also propose a definition of the normalized cross-correlation matrix between two vectors and show a link with the coherence function.

TL;DR: The data visualization systems and methods of this invention provide a powerful tool for visualizing multi-dimensional databases as mentioned in this paper, which can display much larger pivot tables than is possible using conventional interfaces and provide the ability to navigate through complex cubes to identify important structures.
Abstract: The data visualization systems and methods of this invention provide a powerful tool for visualizing multi-dimensional databases. In one exemplary embodiment, the data visualization systems and methods of this invention visualize pivot tables using two novel visual metaphors: a single measure perspective consisting of linked bar charts and a multiscape landscape visualization; and a anchored measures perspective for displaying several measures simultaneously. The data visualization systems and methods of this invention usefully display much larger pivot tables than is possible using conventional interfaces and provide the ability to navigate through complex cubes to identify important structures. In various exemplary embodiments, the data visualization systems and methods of this invention attach to MS Excel™ as an add-on, access pivot tables directly from SQL Server 7.0, and integrate with MS Office.

20 May 2001TL;DR: In this paper, a microwave radio for Doppler radar sensing of vital signs is described using custom DCS1800/PCS1900 base station RFICs, which can detect heart and respiration rates from a distance as large as one meter from the target.
Abstract: A microwave radio for Doppler radar sensing of vital signs is described. This radio was developed using custom DCS1800/PCS1900 base station RFICs. It transmits a single tone signal, demodulates the reflected signal, and outputs a baseband signal. If the object that reflects the signal has periodic motion, the magnitude of the baseband output signal is directly proportional to the periodic displacement of the object. When the signal is reflected off a person's chest, this radio with appropriate baseband filters can detect heart and respiration rates from a distance as large as one meter from the target.
