Accuracy of calibrated-loop transfer.
The accuracy of the 0.001-ml calibrated platinum loop was tested by two methods: visible absorption spectroscopy and weight determinations. By both methods it was demonstrated that the volume of the loop delivery is related to the angle at which the loop is withdrawn from the solution being sampled and the diameter of the container, provided that the volume in the container is adequate to cover...
متن کاملRadiometric Accuracy of Mipas Calibrated Spectra
A precise radiometric calibration of the measured spectra is essential for a good quality of the trace gas retrievals. In order to ensure a high radiometric accuracy, a calibration scenario has to be developed that meets the tradeoff between data quality and the necessary measurement time. Furthermore the radiometric calibration requires an accurate instrument characterisation. This presentatio...
متن کاملMICROSURGICA.L TREATMENT OF UPPER ESOPHAGEAL CARCINOMA (FREE JEJUNAL LOOP TRANSFER)
There are unfortunately a relatively large number of cases of esophageal cancer in Iran as well as other countries, and one of the most difficult problems facing surgeons is the reconstruction of the esophagus and restoration of its function after excision of the tumor. From 1978 to 1987,20 patients (16 male, 4 female) ranging in age from 22 to 68 years were surgically treated for squamous...
متن کاملComputing Rigorous Bounds to the Accuracy of Calibrated Stereo Reconstruction
We deal with the problem of computing rigorous bounds to the position of 3-D points obtained by stereo triangulation when both the camera matrix and the coordinates of image points are affected by measurement errors. By “rigorous bounds” we mean that the true unknown 3-D points are guaranteed to lie within the intervals computed by our method with mathematical certainty. To this end, we first m...
متن کاملAdaptive Loop Transfer Recovery
In this paper, a newmodification term for use in adaptive control is developed to improve robustness of an existing design. The objective is to recover the loop transfer properties of a reference model associated with a nonadaptive control design. Consequently, this term can increase the level of confidence of an adaptive control system for purposes of increased flight safety. An illustrative e...
