in order to obtain maximum information from magnetic and gravity anomaly maps, application of an edgedetection method is necessary. in this regard two commonly used methods are derivative filters and local phase filters. in this paper, a matlab code is expanded to combine an analytic signal filter and a tilt angle filter as a new edge detection filter called asta filter. this method was demonst...

a r t i c l e i n f o Keywords: Regional climate modeling Wildfire potential Drought KBDI Soil moisture NDVI Regional climate modeling is a technique for simulating high-resolution physical processes in the atmosphere, soil and vegetation. It can be used to evaluate wildfire potential by either providing meteorological conditions for computation of fire indices or predicting soil moisture as a ...

The purpose of the present study is to assess large-scale signal modulation produced by two dynamically downscaled Seasonal Forecasting Systems (SFSs) and investigate if additional predictive skill can be achieved, compared driving global-scale Climate Forecast System (CFS). SFSs are evaluated in terms physical values anomaly interannual variability. Downscaled consist two-step dynamical ensemb...

The analytical signal method and its derivatives can be explicitly calculated assessed for analyzing estimating the boundary of geological structures, such as faults or dikes, from potential field anomalies. Gravity east Qeshm Island north coast Sarkhun to Latidan in SE Iran has been measured one-kilometer regular network. regional anomaly effects are deducted Bouguer anomaly, where it get resi...

In this study, 115 samples taken from the stream sediments were analyzed for concentrations of As, Co, Cr, Cu, Ni, Pb, W, Zn, Au, Ba, Fe, Mn, Sr, Ti, U, V and Zr. In order to outline mineralization-derived stream sediments, various mapping techniques including fuzzy factor score, geochemical halos and fractal model were used. Based on these models, concentrations of Co, Cr, Ni, Zn, Ba, Fe, Mn, ...

background: several studies have assessed the correlation of fetal choroid plexus cyst (cpc) and the risk of congenital anomalies, but few ones have discussed isolated cpc (with no other abnormal sonographic finding). objective: the aim of this study was to determine the outcome of isolated fetal choroid plexus cyst and to specify its clinical significance. materials and methods: this cross sec...

Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...

[1] Interannually varying net carbon exchange fluxes from the TransCom 3 Level 2 Atmospheric Inversion Intercomparison Experiment are presented for the 1980 to 2005 time period. The fluxes represent the model mean, net carbon exchange for 11 land and 11 ocean regions after subtraction of fossil fuel CO2 emissions. Both aggregated regional totals and the individual regional estimates are accompa...
