Mapping the ancient port at the archaeological site of Itanos (Greece) using shallow seismic methods
TL;DR: In this article, a shallow seismic survey was carried out at the archaeological site of Itanos, Crete to locate and map the ancient port of ancient Phyllites, and the integration of the seismic data, aerial imagery and archaeological findings indicated that ancient port was surrounded by the sea, the two acropolis to the north, a well to the east and a hill to the south.

Time-varying deconvolution of GPR data in civil engineering
Nikos Economou,Antonis Vafidis,Hamdan Hamdan,G. Kritikakis,N. Andronikidis,Kleisthenis Dimitriadis +5 more
TL;DR: In this paper, an efficient GPR data processing method, which increases the dominant frequency of ground penetrating radar (GPR) data and the temporal resolution, is proposed, which is implemented in the t-f domain.

Attenuation analysis of real GPR wavelets: The equivalent amplitude spectrum (EAS)
Nikos Economou,G. Kritikakis +1 more
TL;DR: In this paper, the robustness of the frequency peak shift (FPS) method was improved by fitting a part of the amplitude spectrum of ground penetrating radar (GPR) data with Ricker, Gaussian, Sigmoid-Gaussian or Ricker-Gaussian functions.

Integration of seismic and image data processing for rockfall monitoring and early warning along transportation networks
Panagiotis Partsinevelos,G. Kritikakis,Nikos Economou,Zach Agioutantis,Achilleas Tripolitsiotis,Stelios P. Mertikas,Antonis Vafidis +6 more
TL;DR: In this paper, a low-cost rockfall monitoring and alerting system is presented, which integrates measurements from a multi-channel seismograph and commercial cameras as the primary equipment for event detection, and a series of algorithms analyze these measurements independently in order to reduce alarms originated by surrounding noise and sources other than rockfall events.

Contribution of electrical tomography methods in geotechnical investigations at Mavropigi lignite open pit mine, Northern Greece
Hamdan Hamdan,N. Andronikidis,G. Kritikakis,Nikos Economou,Zacharias Agioutantis,Paul Schilizzi,Chrysanthos Steiakakis,Christodoulos Papageorgiou,Panagiotis Tsourlos,George Vargemezis,Antonis Vafidis +10 more
TL;DR: In this article, the application of 2D and 3D electrical resistivity methods in geotechnical investigations is explored through a case study in Northern Greece, where fracture zones and discontinuities have been recently observed close to the pit boundaries.
