Group - Hann

Hann. Münden (short for Hannoversch Münden) is the German official name of a town in Lower Saxony, Germany.

Jason Hann is a percussionist for The String Cheese Incident, an American jamband from Boulder, Colorado. Hann grew up in Miami, Florida and is a late addition to SCI.

Georg Hann (January 30, 1897 - December 9, 1950) was an Austrian operatic bass-baritone, particularly associated with the comic (singspiel) German repertory.

Hann is a neighbourhood of Dakar, the capital of Senegal. It is located on the eastern side of the small south facing peninsula on which the old city of Dakar built.

Abstract: Metastasizing lung carcinomas in Hann: Wistar rats. Kamino K, Kohler M, Mohr U. Institute of Experimental Pathology, Hannover Medical School, Germany. In Hann:Wistar rats, 25 weekly subcutaneous injections of dipentylnitrosamine (DPNA) at doses of 0, 62.5, 125 and 250 mg/kg body weight induced lung carcinomas which metastasized partly. The incidence of the primaries was 2.5, 20.0, 77.5 and 100% in the males and 0, 0, 12.5 and 57.5% in the females, respectively. The frequency of metastases was 0, 12.5, 38.7 and 72.5% in the males and 0, 0, 40.0 and 52.2% in the females, respectively. The mos...

Abstract: The sinusoidal model has been a fundamentally important signal representation for coding and analysis of audio. We present an enhancement to sinusoidal modeling in the form of a linear frequency chirp parameter estimator applicable to Hann-windowed quasi-sinusoidal signals. The estimator relies on models of the phase curvature and peak width of a given chirp signal?s FFT magnitude domain peak. We show that different models are applicable for smaller and larger values of the chirp parameter, derived respectively from Taylor series and Fresnel integral analysis of the signal. We construct an est...

Abstract: Abstract In filtered backprojection reconstruction, including the final reconstruction step of the Kinahan and Rogers reprojection algorithm for 3D PET, apodizing windows are used to control the balance between resolution and noise in the output image. Generally, the desire is to use as little apodization as possible, to preserve image resolution, while achieving an acceptable noise level in the reconstructed image. In many circumstances, a Hann window with a cutoff at or below the Nyquist frequency is used with excellent results. The Hann window is continuous in magnitude and slope at its fr...

Abstract: The Search for Extraterrestrial Intelligence, currently being planned by NASA, will require that an enormous amount of data be analyzed in real time by special purpose hardware. It is expected that overlapped Hann data windows will play an important role in this analysis. In order to understand the statistical implication of this approach, it has been necessary to compute detection statistics for overlapped Hann spectra. Tables of signal detection statistics are given for false alarm rates from 10(exp -14) to 10(exp -1) and signal detection probabilities from 0.50 to 0.99; the number of comput...
