on left ventricular ejection fraction, ejection rate and regional wall motion was studied sequentially in 22 stable, resting patients with coronary artery disease using a geometry-independent first-pass radionuclide angiocardiographic technique. All patients improved clinically, in association with a fall in heart rate and therapeutic serum propranolol levels. No significant changes were noted ...

There is an international commitment to develop a comprehensive, coordinated and sustained ocean observation system. However, a foundation for any observing, monitoring or research effort is effective and reliable in situ sensor technologies that accurately measure key environmental parameters. Ultimately, the data used for modelling efforts, management decisions and rapid responses to ocean ha...

A new performance evaluation paradigm for computer vision systems is proposed. In real situation, the complexity of the input data and/or of the computational procedure can make traditional error propagation methods infeasible. The new approach exploits a resampling technique recently introduced in statistics, the bootstrap. Distributions for the output variables are obtained by perturbing the ...

The call for alternative assessments of science achievement grows out of the current constructivist reform in science curriculum and cognitive research. This article presents and applies guidelines for developing performance assessments aligned with this research and reform. We sample classroom activities or tasks from a domain of activities and construct performance assessments with them. Usin...

We present an any-time performance assessment for benchmarking numerical optimization algorithms in a black-box scenario, applied within the COCO benchmarking platform. The performance assessment is based on runtimes measured in number of objective function evaluations to reach one or several quality indicator target values. We argue that runtime is the only available measure with a generic, me...

The purpose of the current research is evaluating performance of SAMA schools of 4th district of Islamic Azad University based on the organizational excellence model of European Foundation for Quality Management (EFQM) for quality management from viewpoints of staff and managers. The research is applied and has a descriptive-survey method. Using a stratified random sampling, 100 respondents wer...
