, it is necessary to develop evaluation approaches and methods that credit IR methods for their ability to retrieve highly relevant documents. This can be done by extending traditional evaluation methods, i.e., recall and precision based on binary relevance assessments, to graded relevance assessments

environments. The proposed methods are (1) a novel application of P-R curves and average precision computations based on separate recall bases for documents of different degrees of relevance, and (2) two novel measures computing the cumulative gain the user obtains by examining the retrieval result up to a

Abstract. Optimizing compilers for object-oriented languages apply static class analysis and other techniques to try to deduce precise information about the possible classes of the receivers of messages; if successful, dynamicallydispatched messages can be replaced with direct procedure calls

Abstract. This work aims at the precise assessment of a recently introduced method that, in ad-dition to damage detection, allows for complete and accurate damage identification (localization) and magnitude estimation. The method is based on Vector–dependent Functionally Pooled (VFP) models

This paper presents precise assessment of steady-state performance of induction motor (IM) operating under voltage unbalance. The variation of two voltage unbalance factors viz. complex voltage unbalance factor (CVUF) and impedance unbalance factor (IUF) with positive sequence voltage component

of contrast agent, procedure time and patient discomfort are expected to be reduced. This paper extends our previous work [1] in two ways. First, the study to assess the precision of the machine-based registration is completed, including various C-arm orientations and different focal lengths. A mean 2D error

. The models use two classes of features: topicality features that use adaptive language models in a novel way to detect broad changes of topic, and cue-word features that detect occurrences of specific words, which may be domain-specific, that tend to be used near segment boundaries. Assessment of our

During an interventional neuroradiology exam, knowing the exact location of the catheter tip with respect to the patient can dramatically help the physician. An image registration between digital subtracted angiography (DSA) images and a volumic pre-operative image (magnetic resonance or computed tomography volumes) is a way to infer this important information. This mono-patient multimodality matching can be reduced to finding the projection matrix that transforms any voxel of the volume onto the DSA image plane. This modelization is unfortunately not valid in the case of distorted images, which is the case for DSA images. A classical angiography room can now generate 3D X-ray angiography volumes (3DXA). Since the DSA images are obtained with the same machine, it should be possible to deduce the projection matrix from the sensor data indicating the current machine position. We propose an interpolation scheme, associated to a pre-operative calibration of the machine that allows...

BACKGROUND AND PURPOSE: Quantitative markers of Alzheimer disease (AD), particularly in the early stages, are needed for clinical assessment and monitoring. We have evaluated a novel method to segment and visualize the ventricular system and obtain volumetric measures thereof. The temporal horn

SUMMARY Serum lipids and lipoproteins were measured in 67 high-risk children, aged between 2 and 17 years, who were the offspring of 33 fathers with hypercholesterolaemia. 18 of the 33 fathers had had a myocardial infarction (MI) before 44 years of age. In 15 of the fathers there was no history of accelerated coronary heart disease (CHD). No difference in the concentrations of the serum lipids and lipoproteins was found between the children whose fathers had a history of MI (n = 31) and the children with no family history of CHD (n = 36). Serum lipids and lipo-proteins were also measured in a control group of 19 children, aged between 2 and 17, whose parents were normolipaemic and had no history of atherosclerosis. Serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDLc) concentrations were significantly higher-547 ± 1.36 mmol/l (211 ± 52 mg/100 ml) and 3-55 ± 1.16 mmol/l (137 ± 45 mg/100 ml) respectively-in the 67 'high-risk ' children than in the control group-TC, 4-46 ± 0*64 mmol/l (172 ± 25 mg/ 100 ml); LDLc, 2.56 ± 0.64 mmol/l (99 + 25 mg/100 ml). No statistically significant difference was found in serum triglyceride (TG) or high-density lipoprotein-cholesterol (HDLc) concen-trations between these two groups. In 7 of the high-risk children, raised levels of serum TC>5*74 mmol/l (>221 mg/100 ml) were
