A key problem in computational auditory scene analysis (CASA) is monaural speech segregation, which has proven to be very challenging. For monaural mixtures, one can only utilize the intrinsic properties of speech or interference to segregate target speech from background noise. Ideal binary mask (IBM) has been proposed as a main goal of sound segregation in CASA and has led to substantial impr...

We investigate the packet delay and loss characteristics of the wide-area HIPPI-based CASA gigabit testbed. Developed for high{speed local area device interconnects, HIPPI is a point{to{point, connection{oriented protocol. We show HIPPI blocking can degrade performance by increasing delay and/or packet loss. In the CASA network under conditions of blocking, a tradeoo exists between packet loss ...

Background: Although sperm selection according to morphologic and motility characteristic, made to some what the fertility successful, but sperm’s normal morphology cannot demonstrate sperm DNA competence. Since the health of sperm DNA is affecting the results of assisted reproductive technology; the aim of this study is to evaluate semen parameters measured by CASA with sperm chromatin abnorma...

In this paper we propose a running demonstration of coupling between an intermediate processing step (named CASA), based on the harmonicity cue, and partial recognition, implemented with a HMM/ANN multistream technique 2]. The model is able to recognise words corrupted with narrow band noise, either stationary or having variable center frequency. The principle is to identify frame by frame the ...

In 2010 the Australian Civil Aviation Safety Authority (CASA) published a paper titled ‘Biomathematical Fatigue Modelling in Civil Aviation Fatigue Risk Management: Application Guidance’. In March 2014 an updated version of this document titled ‘Biomathematical Fatigue Models Guidance Document’ was released. The intent of the documents is to provide the aviation industry with updated guidance o...
