RANSAC (Random Sample Consensus) [2] is a popular algorithm in computer vision for fitting a model to data points contaminated with many gross outliers. Traditionally many small hypothesis sets are chosen randomly; these are used to generate models and the model consistent with most data points is selected. Instead we propose that each hypothesis set chosen is the one most likely to be correct,...

We present a physiologically based model that describes major properties of muscles and segmental dynamics during FES assisted standing-up. It accounts for relevant time-dependent and nonlinear properties (temporal and spatial summation, muscle fatigue, force-length and force-velocity relations, viscoelastic effects, nonlinear moment arms, choice of muscles stimulated, seat and upperbody intera...

It is a great pleasure for me to welcome you to our annual Conference on European Economic Integration. The Oesterreichische Nationalbank (OeNB) has been hosting this event for many years, offering a forum for lively debates between distinguished panelists from national and international institutions, politics, banking and academia. I am glad that such a sizeable number of participants and spea...

ISIS is a developmental decision support system that helps physicians select diagnostic imaging procedures. It uses case-based reasoning, an artificial-intelligence approach that emphasizes reasoning and planning from prior experience. The development, training, and evaluation of a prototype system were used to guide the development of ISIS. To realize a clinically useful system, particular emp...

This paper presents two new strategies to speed up connected component labeling algorithms. The first strategy employs a decision tree to minimize the work performed in the scanning phase of connected component labeling algorithms. The second strategy uses a simplified union-find data structure to represent the equivalence information among the labels. For 8-connected components in a two-dimens...

The impact of steam quality, circulation rate and pressure difference between the well pair during SAGD initialization using steam circulation was explored through the use of numerical simulations employing a discretized wellbore model. These operating parameters appear to affect uniformity of reservoir heating, occurrence of steam breakthrough and time required to establish communication betwe...

BACKGROUND Follow-up examinations are commonly performed after primary treatment for women with breast cancer. They are used to detect recurrences at an early (asymptomatic) stage. This is an update of a Cochrane review first published in 2000. OBJECTIVES To assess the effectiveness of different policies of follow-up for distant metastases on mortality, morbidity and quality of life in women ...

Impressive progress has been made in global surgery in the past 10 years, and now serious and evidence-based national strategies are being developed for scaling-up surgical services in sub-Saharan Africa. Key to achieving this goal requires developing a realistic country-based estimate of burden of surgical disease, developing an accurate estimate of existing need, deve...
