This paper describes a system for Chinese pronunciation and listening training on the Internet. The target Chinese stop consonants /b/, /p/, /d/, /t/ were chosen for this experiment. In the pronunciation component, a dynamic low-pass ltered power(DLP) was used as an acoustic feature to discriminate between aspirated sounds and unaspirated sounds. With the sounds uttered by Chinese native speake...

A new algorithm is introduced that performs spatially adaptive enhancement on low-light visible and infrared images of the same scene and fusion of these into one composite image. The algorithm involves lowpass/high-pass ltering and simple nonlinear operations that can be table driven. Examples of the processing on image data collected in eld tests are given.

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...
