This paper presents a new algorithm for correcting incorrect line drawings—incorrect projections of a polyhedral scene. Such incorrect drawings arise, e.g., when an image of a polyhedral world is taken, the edges and vertices are extracted, and a drawing is synthesized. Along the way, the true positions of the vertices in the 2D projection are perturbed due to digitization errors and the prepro...

The active site of activated Factor IX (FIXa) and related blood-coagulation enzymes is surrounded by a number of highly variable surface loops, which contribute to the characteristic substrate specificity of each individual enzyme. FIX residue Lys(316) is located in one of these loops and mutation of this residue to Glu is associated with haemophilia B. In the present study we investigated the ...

This study is to evaluate the sensitivity of Aerosol Optical Depth (AOD τ) to aerosol vertical profile and type, using the Moderate Resolution Imaging Spectroradiometer (MODIS) collection 6 algorithm over land. Four experiments were performed, using different aerosol properties including 3 possible non-dust aerosol models and 14 vertical distributions. The algorithm intrinsic uncertainty was in...

The ability to calculate drug dosages correctly is an essential skill for registered nurses to possess. Performing drug calculations accurately is not a skill that new graduates have the luxury of developing over time. Drug errors are in many instances directly related to either the administration of an incorrect dose or incorrect infusion rate caused by calculation errors. A strategy for imple...

This paper provides improved confidence assessment for detection of word-level speech recognition errors, out of domain utterances and incorrect concepts in the CU Communicator system. New features from the speech understanding component are proposed for confidence annotation at utterance and concept levels. We have considered a neural network to combine all features in each level. Using the da...

In Belgian hospitals, drug histories of patients taken on admission are generally collected by medical trainees, physicians and nurses. As errors in drug histories may lead to medication errors and adverse drug events, we aimed at comparing the data obtained by a clinical pharmacist with those obtained by the nurses in a surgical orthopaedic ward. In this four months study, 50 patients, with a ...

A new form of consider covariance analysis suitable for application to square-root information filters with a wide variety of model errors is presented and demonstrated. A special system formulation is employed, and the analysis draws on the algorithms of square-root information filtering to provide generality and compactness. This analysis enables one to investigate the estimation errors that ...
