This study indirectly tests whether American, Greek and Korean listeners can classify low-pass filtered utterances of English, German, Greek, Italian, Korean and Spanish into rhythm classes, by examining how they rate each utterance’s rhythm in comparison to a series of non-speech trochees. Such classification was difficult for all groups of listeners and did not support the rhythmic classifica...

The concept of programmable cascaded low-pass filter method of flux vector synthesis has been introduced in the literature [1]. In this paper, the idea will be expanded, analyzed, improved, and then applied to a stator flux oriented 100-kW electric vehicle drive. It was verified that the flux estimation works well at zero speed finite torque start-up mode and lowand high-speed field weakening r...

This report describes a technique to detect curvature. The technique uses local polynomial fitting on a local orientation description of an image. The idea is based on the theory of rotational symmetries which describes curvature, circles, starpatterns etc. The local polynomial fitting is shown to be equivalent to calculating partial derivatives on a lowpass version of the local orientation. Th...

This paper presents a new approach and prototype system for karaoke vocal or instrument removal. The algorithm estimates the singer’s location and spatial transfer function from a stereo recording, then mutes components in the recording according to the estimated orientation. At the current stage, estimation is obtained by analyzing solo segments in the recording. This algorithm turns to be rob...

A common tactile display design uses an array of mechanical pins covered by a rubber layer which acts as a spatial low pass filter. To characterize the perceptual relationship between this rubber layer and shape rendering, we conducted psychophysical experiments to examine the perception of a vertical line stimulus felt using rubber covers of varying thickness and stiffness. We found no signifi...

It is shown that the addition of a low pass RC filter to the current ATLAS Tile Calorimeter 3-in-1 card decreases the high frequency noise. A peak in the output voltage is found for 29 Mhz input noise but is filtered out by the same low pass filter.

Nanopore-based single-molecule sequencing techniques exploit ionic current steps produced as biomolecules pass through a pore to reconstruct properties of the sequence. A key task in analyzing complex nanopore data is discovering the boundaries between these steps, which has traditionally been done in research labs by hand. We present an automated method of analyzing nanopore data, by detecting...

New extremal properties of Daubechies 4-tap orthonormal filters are given: They maximize a certain functional, have the largest gain in (0, π/2), and allow maximum energy compaction in [0, π/2]. These properties do not carry over to Daubechies filters of arbitrary length. They complement what is known about Daubechies filters and highlight the specific role of the 4-tap filter. Moreover, we dem...

In this paper, we present a new method and its preliminary results within the context of pattern analysis and recognition. This method is based on the multiscale analysis of a curve and deals with the contour of planar objects. Our method uses a low-pass Gaussian kernel to gradually smooth the contour by decreasing the filter bandwidth. Applying gain control to the smoothed contour stretches it...
