Are Any Public-Reported Earthquake Precursors Valid
(European Geosciences Union, 2004)
This article examines retrospective public-supplied precursor reports statistically, and confirms published hypotheses that some alleged precursors within 100 km and within a day prior to the large 1995 Kobe and 1999 Izmit ...
Liquefaction Severity Map for Aksaray City Center (Central Anatolia, Turkey)
(Copernicus Gesellschaft Mbh, 2008)
Turkey having a long history of large earthquakes have been subjected to progressive adjacent earthquakes. Starting in 1939, the North Anatolian Fault Zone (NAFZ) produced a sequence of major earthquakes, of which the Mw ...
Determination Of The Rockfall Source In An Urban Settlement Area By Using A Rule-Based Fuzzy Evaluation
(Copernicus Gesellschaft Mbh, 2006)
The evaluation of the rockfall initiation mechanism and the simulation of the runout behavior is an important issue in the prevention and remedial measures for potential rockfall hazards in highway protection, in forest ...
Landslide Susceptibility Assessment of Se Bartin (West Black Sea Region, Turkey) by Artificial Neural Networks
(Copernicus Gesellschaft Mbh, 2005)
Landslides are significant natural hazards in Turkey, second only to earthquakes with respect to economic losses and casualties. The West Black Sea region of Turkey is known as one of the most landslide-prone regions in ...
Computerized Ionospheric Tomography With The Iri Model
(Elsevier Sci Ltd, 2007)
Computerized ionospheric tomography (CIT) is a method to estimate ionospheric electron density distribution by using the global positioning system (GPS) signals recorded by the GPS receivers. Ionospheric electron density ...
A New Algorithm for High-Quality Ionogram Generation and Analysis
(Amer Geophysical Union, 2002)
Standard digital ionograms that are generated by fast Fourier transform or autoregressive modeling suffer from high interference levels due to other users of the HF channel which produce artifacts and distortion, hence ...
Regional Tec Mapping with Random Field Priors and Kriging
(Amer Geophysical Union, 2008)
Total Electron Content ( TEC) is an important parameter in monitoring ionospheric variability. In a given region, TEC can be obtained only by interpolation of measurements due to sparsity of the useful data. The lack of a ...
Regularized Estimation of Tec from Gps Data for Certain Midlatitude Stations and Comparison with the Iri Model
(Elsevier Sci Ltd, 2007)
Regularized estimation of Total Electron Content (Reg-Est) is a novel technique which can combine signals from all the satellites for a given instant and given station and estimate the vertical TEC (VTEC) values for any ...
Tomographic Reconstruction Of The Ionospheric Electron Density As A Function Of Space And Time
(Elsevier Sci Ltd, 2009)
Electron density distribution is the major determining parameter of the ionosphere. Computerized Ionospheric Tomography (CIT) is a method to reconstruct ionospheric electron density image by computing Total Electron Content ...
Multipath Separation-Direction Of Arrival (Ms-Doa) With Genetic Search Algorithm For Hf Channels
(Elsevier Sci Ltd, 2009)
Direction-of-Arrival (DOA) defines the estimation of arrival angles of an electromagnetic wave impinging oil a set of sensors. For dispersive and time-varying HF channels, where the propagating wave also suffers from the ...
