Sudden drop of fractal dimension of electromagnetic emissions recorded prior to significant earthquake
S. M. Potirakis, G. Minadakis, K. Eftaxias
The variation of fractal dimension and entropy during a damage evolution process, especially approaching critical failure, has been recently investigated. A sudden drop of fractal…
Relation between seismicity and pre-earthquake electromagnetic emissions in terms of energy, information and entropy content
S. M. Potirakis, G. Minadakis, K. Eftaxias
In this paper we show, in terms of Fisher information and approximate entropy, that the two strong impulsive kHz electromagnetic (EM) bursts recorder prior to the Athens EQ (7 Sept…
Linking electromagnetic precursors with earthquake dynamics: an approach based on nonextensive fragment and self-affine asperity models
G. Minadakis, S. M. Potirakis, C. Nomicos +1
EM emissions in a wide frequency spectrum ranging from kHz to MHz are produced by opening cracks, which can be considered as precursors of general fracture. An important feature, o…
TEI Piraeus students' knowledge on the beneficial applications of nuclear physics: Nuclear energy, radioactivity - consequences
Mirofora Pilakouta
The recent nuclear accident in Japan revealed the confusion and the inadequate knowledge of the citizens about the issues of nuclear energy, nuclear applications, radioactivity and…
Simulated Performance Of Algorithms For The Localization Of Radioactive Sources From A Position Sensitive Radiation Detecting System (COCAE)
K. Karafasoulis, K. Zachariadou, S. Seferlis +4
Simulation studies are presented regarding the performance of algorithms that localize point-like radioactive sources detected by a position sensitive portable radiation instrument…
An improved method for the computation of the Moore-Penrose inverse matrix
Vasilios N. Katsikis, Dimitrios Pappas, Athanassios Petralias
In this article we provide a fast computational method in order to calculate the Moore-Penrose inverse of singular square matrices and of rectangular matrices. The proposed method…
