Among the blazars detected by the Fermi satellite, we have selected the 23 blazars that in the three months of survey had an average γ–ray luminosity above 10 erg s. For 17 out of the 23 sources we found and analysed X–ray and optical–UV data taken by the Swift satellite. With these data, implemented by archival and not simultaneous data, we construct the spectral energy distributions, and inte...

Statistical graphics play a crucial role in exploratory data analysis, model checking and diagnosis. Until recently there were no formal visual methods in place for determining statistical significance of findings. This changed, when Buja et al. (2009) conceptually introduced two protocols for formal tests of visual findings. In this paper we take this a step further by comparing the lineup pro...

Uniformly most powerful confidence distributions are obtained for parameters in selected models of the exponential family. A conditioning on selection event as well sufficient statistics nuisance guarantees valid post-selection inference. Optimal intervals directly from distribution without requiring an inversion pivotal quantities. Simulations showcase that method works also when all misspecif...

Many research results of AFS (Axiomatic Fuzzy Set) theory and its applications have been published and reported since Liu proposed it in [20] in 1995. In this paper, an over review of AFS theory is done by both theory analysis and illustrate examples to explain the abstract notations and theorems in order to elicit the potential applications and the further research topics. Many well-known data...

Corner matching in digital images is a key step in several applications in computer vision such as motion estimation, object recognition and localization, 3D reconstruction etc. Accuracy and reliability of corner matching algorithms are two important criteria. In this paper, corner correspondence between two images is established in the presence of intensity variations, inherent noise and motio...

Most systems designed for the verification of security protocols operated under the unproved assumption that an attack can only result from the combination of a fixed number of message transformations, which altogether constitute the capabilities of the so-called Dolev-Yao intruder. In this paper, we prove that the Dolev-Yao intruder can indeed emulate the actions of an arbitrary adversary. In ...

Let X denote a locally compact metric space and φ : X → X be a continuous map. In the 1970s L. Zadeh presented an extension principle, helping us to fuzzify the dynamical system (X, φ), i.e., to obtain a map Φ for the space of fuzzy sets on X. We extend an idea mentioned in [P. Diamond, A. Pokrovskii, Chaos, entropy and a generalized extension principle, Fuzzy Sets and Systems 61 (1994)] and we...
