Preliminary System Safety Assessment (PSSA) is a key stage of the safety process in the civil aerospace community. It is identified in ARP 4754/4761 as the stage in the safety process concerned with validating systems architecture, and producing derived safety requirements on system components. A very similar approach has been adopted by EUROCONTROL for Air Traffic Management (ATM). The process...

Arabidopsis thaliana has three genes, Ape1L, Ape2, and Arp, that show homology to abasic (apurinic/apyrimidinic) endonuclease genes of bacterial, yeast, or animal cells. In bacteria, yeast, and animals, abasic endonucleases function in base excision repair of oxidized and other modified DNA bases. Here we report that plants with knock-out mutations in any one of Ape1L, Ape2, or Arp show no appa...

Adaptive Reduced Path Successive Cancellation List (ARP-SCL) decoding for polar codes is proposed in this paper. The aim here to reduce the complexity of conventional (SCL) and a previously SCL (RP-SCL) decoders. reduction obtained at low moderate signal noise power ratio (SNR) regions. operation ARP-SCL decoder relied on calculation different optimum pruning parameters according operating SNR,...

Spoofing detection for automatic speaker verification (ASV), which is to discriminate between live and artificial speech, has received increasing attentions recently. However, the previous studies have been done on the clean data without significant noise. It is still not clear whether the spoofing detectors trained on clean speech can generalise well under noisy conditions. In this work, we pe...

Propagating star formation in a collisional ring galaxy Arp 10 is investigated by a complex approach , which includes the broad-and narrow-band photometry, long-slit spectroscopy, and scanning Fabry-Perot spectroscopy. The ionized gas velocity field obtained with best spatial resolution to date indicates a non-isotropic expansion of the outer ring with a maximum velocity 110 km s −1. Strong ver...

Artificial reverberation (AR) models play a central role in various audio applications. Therefore, estimating the AR model parameters (ARPs) of reference is crucial task. Although few recent deep-learning-based approaches have shown promising performance, their non-end-to-end training scheme prevents them from fully exploiting potential deep neural networks. This motivates introduction differen...

The problem of extracting a “signal” xn generated by a dynamical system from a times series yn = xn + en, where en is an observational error, is considered. It is shown that consistent signal extraction is impossible when the errors are distributed according to a density with unbounded support and the underlying dynamical system admits homoclinic pairs. It is also shown that consistent signal e...
