Continuous Wavelet Transform and CNN for Fault Detection in a Helical Gearbox by Iulian Lupea, Mihaiela Lupea

“…Through CWT, the vibration signal is decomposed into 2D time-frequency grayscale images, with a filter bank of ten voices per octave in the frequency band of interest. Three 2D-CNN-based models trained on the CWT-based representation of the vibration signals measured on individual accelerometer axes (<i>X</i>, <i>Y</i>, and <i>Z</i>) are proposed to detect the four health states (one normal and three faulty) of the helical gearbox, regardless of the selected load level or speed on the test rig. …”

Schon wieder das Lied!. Robert Schumanns »In der Fremde« und die Kriterien musikalischer Analyse by Felix Diergarten

“…Despite this, or precisely because of it, this article takes up the first song of the Liederkreis op. 39 (“In der Fremde”) once again and presents it against the background of some recent developments in historically informed analysis, including in particular the use of figured bass, rule of the octave and schemata, in order to take a look at present-day possibilities of analysis. …”

Selective Vulnerability of the Cochlear Basal Turn to Acrylonitrile and Noise by B. Pouyatos, C. A. Gearhart, A. Nelson-Miller, S. Fulton, L. D. Fechter

“…It was previously noted that the high-frequency or basal turn of the cochlea was particularly vulnerable to the combined effects of acrylonitrile and noise when the octave band noise (OBN) was centered at 8 kHz. Normally, such a noise would be expected to yield damage at a more apical region of the cochlea. …”

Über den »unisonierenden Dualismus« im ersten Satz von Schuberts Streichquartett G-Dur, D. 887 by Sebastian Urmoneit

“…In the development it becomes clear that Schubert, by means of ‘compositional science’ that has been essential to the works of the string quartet genre since Haydn, uses the procedure of a symmetrical division of the octave to expose the danger of losing himself in ‘bad infiniteness’ precisely where he supposedly proceeds in a particularly systematic manner.…”
