There has been much recent interest in application of the pool-adjacent-violators (PAV) algorithm for the purpose of calibrating the probabilistic outputs of automatic pattern recognition and machine learning algorithms. Special cost functions, known as proper scoring rules form natural objective functions to judge the goodness of such calibration. We show that for binary pattern classifiers, t...

The main methodological drawback to use physiological measures as indicators of arousal is, the large interindividual variability of autonomic responses hindering the direct comparability, between individuals. The present methodology has been tested in two cohorts (n1=910, n2=845) of, pilot applicants during a selection procedure. Physiological data were obtained during two mentally, demanding ...

Discrete log based identiication and signature schemes are well-suited to identity proof and signature generation, but not suitable for veriication, by smart cards, due to their highly asymmetric computational load between the prover/signer and the veriier. In this paper, we present very eecient and practical protocols for fast veriication in these schemes, where the veriier with limited comput...

The research objectives were to identify the secondary metabolite components, total phenolic content and determine antioxidant activity of ethanol extract red betel leaf (Piper crocatum Ruiz & Pav.). extraction process was carried out by materation using as a solvent. Determination colorimetrically with Folin-Ciocalteu reagent measured at maximum wavelength 765 nm. DPPH method spectrophotom...

We present the first far-IR observations of the solar-type stars δ Pav, HR 8501, 51 Peg and ζ2 Ret, taken within the context of the DUNES Herschel open time key programme (OTKP). This project uses the PACS and SPIRE instruments with the objective of studying infrared excesses due to exoKuiper belts around nearby solar-type stars. The observed 100 μm fluxes from δ Pav, HR 8501, and 51 Peg agree ...

We present phase-resolved XMM-Newton data of three short period polars: V347 Pav, GG Leo and EU UMa. All three systems show one dominant accretion region which is seen for approximately half of the orbital cycle. GG Leo shows a strong dip feature in its X-ray and UV light curves which is due to absorption of X-rays from the accretion site by the accretion stream. The emission in the case of EU ...
