These lines are the intersections of the plane through the point p in the world and the centres of the left and right cameras with the two camera focal planes (see Figure 1). These epipolar lines are formed by the intersections of the pencil of planes through the line joining the image centres with the camera focal planes. Hence such lines form a pencil passing through the point of intersection...

BACKGROUND Despite the increasing use of real-time PCR in the diagnosis and management of viral infections, there are no published studies adequately addressing the optimum number of calibrators, the number of replicates of each calibrator, and the frequency with which calibration needs to be repeated. This study was designed to address these issues. METHODS Cycle threshold data (ABI 7700) wa...

BACKGROUND The addition of a calibration curve with every run is both time-consuming and expensive for clinical mass spectrometry assays. We present alternative calibration strategies that eliminate the need for a calibration curve except as required by laboratory regulations. METHODS We measured serum nortriptyline concentrations prospectively in 68 patients on 16 days over a 2-month period ...

Introduction: In radiotherapy treatment planning system (TPS), basic input is the data from computed tomography (CT) scan, which takes into account the effect of inhomogeneities in dose calculations. Measurement of CT numbers may be affected by scanner-specific parameters. Therefore, it is important to verify the effect of different CT scanning protocols on Hounsfield unit (HU) and its impact o...

a method for the simultaneous determination of sulfamethoxazole (smx) and trimethoprim (tmp), based on a direct determination of smx after diazotization and coupling with 2-naphthol by visible spectrophotometry and an indirect determination of tmp in the uv region by difference was developed. by the suggested procedure, it was possible to analyze smx and tmp in pharmaceutical preparations witho...

soil conservation service curve number method (scs-cn) is a widely applied technique for predicting direct runoff from rainfall has been used around the world. in this study, the curve number maps and entry physical model data of kheyrud basin to hec-hms model, the hec-geohms extension in arcgis software and google earth satellite images were used. in addition to the statistical analysis of sur...
