The ALEXIS Point Source Detection Effort

Effective Segmentation based on Vocal Effort Change Point Detection

Non-neutral speech data has a strong negative impact on speech processing systems such as Automatic Speech Recognition (ASR) or speaker ID systems [1]. It is therefore necessary to detect and segment non-neutral speech data before further processing steps. Alternatively, the detection and segmentation of non-neutral speech segments from an input speech stream can be used in speech analysis and ...

Visual Detection of Point Source Targets

Impacts of the Detection of Cassiopeia A Point Source.

Very recently the Chandra first light observation discovered a point-like source in the Cassiopeia A supernova remnant. This detection was subsequently confirmed by the analyses of the archival data from both ROSAT and Einstein observations. Here we compare the results from these observations with the scenarios involving both black holes (BHs) and neutron stars (NSs). If this point source is a ...

Asian languages reveal a continuum from quasi-disyllables to highly eroded monosyllables. These variegated states are now understood to be different stages along a common evolutionary path. An overview is proposed, beginning with the earliest stages of monosyllabicization, before the generalization of a strictly monosyllabic phonological structure. The well-documented processes of consonantal d...

The effect of source shield on landmine detection

Background: Several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. Neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. The aim of this study is to use backscattered neutron for landmine detection. Materials ...
