All-Optical FSO Relaying Under Mixture-Gamma Fading Channels and Pointing Errors
Nikolaos I. Miridakis, Dimitrios D. Vergados, Angelos Michalas
The performance of all-optical dual-hop relayed free-space optical communication systems is analytically studied and evaluated. We consider the case when the total received signal…
EGC Reception for FSO Systems Under Mixture-Gamma Fading Channels and Pointing Errors
Nikolaos I. Miridakis, Theodoros A. Tsiftsis
The performance of equal gain combining reception at free-space optical communication systems is analytically studied and evaluated. We consider the case when the total received si…
Intrinsic limits on resolutions in muon- and electron-neutrino charged-current events in the KM3NeT/ORCA detector
S. Adrián-Martínez, M. Ageron, S. Aiello +250
Studying atmospheric neutrino oscillations in the few-GeV range with a multimegaton detector promises to determine the neutrino mass hierarchy. This is the main science goal pursue…
Distributed Spatial Multiplexing Systems with Hardware Impairments and Imperfect Channel Estimation under Rank- Rician Fading Channels
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Corbett Rowell
The performance of a multiuser communication system with single-antenna transmitting terminals and a multi-antenna base-station receiver is analytically investigated. The system op…
On the Joint Impact of Hardware Impairments and Imperfect CSI on Successive Decoding
Nikolaos I. Miridakis, Theodoros A. Tsiftsis
In this paper, a spatial multiplexing multiple-input multiple-output (MIMO) system when hardware along with RF imperfections occur during the communication setup is analytically in…
Letter of Intent for KM3NeT 2.0
S. Adrián-Martínez, M. Ageron, F. Aharonian +244
The main objectives of the KM3NeT Collaboration are i) the discovery and subsequent observation of high-energy neutrino sources in the Universe and ii) the determination of the mas…
Aspects and challenges of mashup creator design
Lampros Goussis, Ioannis E. Foukarakis, Dimitrios N. Kallergis
With the advent of Web 2.0, an increasing number of web sites has started offering their data over the web in standard formats and exposed their functionality as APIs. A new type o…
Deep sea tests of a prototype of the KM3NeT digital optical module
S. Adrián-Martínez, M. Ageron, F. Aharonian +247
The first prototype of a photo-detection unit of the future KM3NeT neutrino telescope has been deployed in the deep waters of the Mediterranean Sea. This digital optical module has…
On the recent seismic activity at Kefalonia island (Greece): Manifestations of an Earth system in critical state
Y. Contoyiannis, S. M. Potirakis, J. Kopanas +4
In this paper we show, in terms of fracture-induced electromagnetic emissions (EME) that the Earth system around the focal areas came to critical condition a few days before the oc…
Current challenges for preseismic electromagnetic emissions: shedding light from micro-scale plastic flow, granular packings, phase transitions and self-affinity notion of fracture process
K. Eftaxias, S. M. Potirakis
Are there credible electromagnetic (EM) EQ precursors? This a question debated in the scientific community and there may be legitimate reasons for the critical views. The negative…
Dynamical analogy between economical crisis and earthquake dynamics within the nonextensive statistical mechanics framework
Stelios M. Potirakis, Pavlos I. Zitis, Konstantinos Eftaxias
The field of study of complex systems considers that the dynamics of complex systems are founded on universal principles that may be used to describe a great variety of scientific…
On the puzzling feature of the silence of precursory electromagnetic emissions
K. Eftaxias, S. M. Potirakis, T. Chelidze
It has been suggested that fracture-induced MHz-kHz electromagnetic (EM) emissions, which emerge from a few days up to a few hours before the main seismic shock occurrence permit a…
The Earth as a living planet: human-type diseases in the earthquake preparation process
Y. F. Contoyiannis, S. M. Potirakis, K. Eftaxias
The new field of complex systems supports the view that a number of systems arising from disciplines as diverse as physics, biology, engineering, and economics may have certain qua…
Dynamical analogy between epileptic seizures and seismogenic electromagnetic emissions by means of nonextensive statistical mechanics
Konstantinos Eftaxias, George Minadakis, Stelios. M. Potirakis +1
The field of study of complex systems considers that the dynamics of complex systems are founded on universal principles that may be used to describe a great variety of scientific…
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…
