Maximal light use efficiency (LUE) is an important ecological index of a vegetation essential attribute, and a key parameter of the LUE-based model for estimating large-scale vegetation productivity by remote sensing technology. However, although currently used in different models there still exists extensive controversy. This paper takes the Zoige Plateau in China as a case area to develop a n...

Most of the features of Cover Song Identification (CSI), for example, Pitch Class Profile (PCP) related features, are based on the musical facets shared among cover versions: melody evolution and harmonic progression. In this work, the perceptual feature was studied for CSI. Our idea was to modify the Perceptual Linear Prediction (PLP) model in the field of Automatic Speech Recognition (ASR) by...

The use of solid-state transmitters is becoming increasingly viable for atmospheric radars and is a key part of the strategy to realize any dense network of low-powered radars. However, solid-state transmitters have low peak powers and this necessitates the use of pulse compression waveforms. In this paper frequency diversity in a wideband waveform design is proposed to mitigate the low sensiti...

In this paper, we propose a computational auditory scene analysis (CASA)–based front–end for two–microphone speech recognition in a car environment. One of the important issues associated with CASA is the accurate estimation of mask information for target speech separation within multiple microphone noisy speech. For such a task, the time–frequency mask information is compensated through the si...

In this paper, we propose a mask estimation method for a computational auditory scene analysis (CASA) based speech recognition front-end using speech obtained from two microphones. The proposed mask estimation method incorporates the observation that the mask information should be correlated over contiguous analysis time frames and adjacent frequency channels. To this end, two different hidden ...

The impacts of implementing Effects Based Operations (EBO) on Course of Action (COA) development and evaluation will be significant. Because EBO focuses on producing effects from military activities, as opposed to the direct result of attacking targets, there is an opportunity to develop a significantly higher number of COAs that achieve the desired effects. Consequently, EBO planning will sign...

The Computers Are Social Actors (CASA) paradigm asserts that human computer users interact socially with computers, and has provided extensive evidence that this is the case. In this experiment (n = 134), participants received either praise or criticism from a computer. Independent variables were the direction feedback (praise or criticism), and voice channel (verbal or text-only). Dependent va...

Optical fiber networks may one day offer potential capacities exceeding 10 terabits/sec. This paper describes present gigabit network techniques for distributed computing as illustrated by the CASA,gigabit testbed, and then explores future all-optic network architectures that offers increased capacity, more optimized level of service for a given application, high fault tolerance, and dynamic re...

The small change in the spectral slope of the overall intensity of cosmic rays near 1 PeV may be associated with the endpoint energy of supernova shock acceleration. A crucial test of this connection and other ideas of the origin of the spectral ‘knee’ is the reliable determination of the variation of elemental composition in this region. Recent measurements at the DICE/CASA/MIA air shower inst...

We describe a new model of CASA labelling which assigns to each time-frequency region a probability "clean" enough to feed a multistream recogniser only adapted to clean data. This labelling process is based on the harmonicity of the speech. The probability is evaluated according to a SNR-feature mapping and the choice of a SNR decision threshold. This allows an extension of a previous method [...
