rely on indirect evidence of nodal metastases. These include nodal enlargement, three or more borderline–sized nodes in a primary drainage pathway, and a nodal morphology showing a change from an elliptical to a spherical shape. The development of accurate radiologic criteria is important since 25% or more of patients presenting with head and neck cancer and no clinically palpable neck disease ...
متن کاملOptimal range and Doppler centroid estimation for a ScanSAR system
llstimation This paper presents a new range and Doppler centroid estimation algorithm for a ScanSAR system. Its accurate range and Doppler centroid estimates lead to refined radar pointing angles, which enables the ScanSAR imagery meeting its radiometric requirements. This algorithm attains an accuracy equal to the Cramer Rae's lower bound for both the homogeneous and quasi-homogeneous targets....
متن کاملMixed two-stage derivative estimator for sensitivity analysis
In mathematical modeling, determining most influential parameters on outputs is of major importance. Thus, sensitivity analysis of parameters plays an important role in model validation. We give detailed procedure of constructing a new derivative estimator for general performance measure in Gaussian systems. We will take advantage of using score function and measure-value derivative estimators ...
متن کاملComparison of Doppler Centroid Estimation Methods in SAR
This paper compares five Doppler centroid estimation methods which are :energy balancing, matched-correlation , maximum likelihood, correlation Doppler estimator(CDE) and sign Doppler estimator (SDE). Their estimation performances in raw data domain and image domain are studied. The computer simulation results are presented. ERS-1 raw data are also used to test the performances of every method....
متن کاملSensitivity Analysis and Finding the Stability Region with Adding DMUs in DEA
One of the important issues in data envelopment analysis (DEA) is sensitivity analysis. Heretofore the existent studies have considered the data modification of inputs and outputs in one or multiple DMUs. In this paper the number of DMUs is increased and a stability region is obtained in by applying defining hyperplanes in which if the added DMU (only one DMU) is in this region then all of the...
