To study and implement a computer evaluation system for spoken English pronunciation is important for learners to improve their spoken English. This paper introduces an undergraduate-oriented evaluation model of spoken English pronunciation and its related system, with four evaluation parameter of accuracy, speed, rhythm and intonation. This paper illustrates the necessity of each evaluation index,...
The excitation specificity of QT dynamic parameters was tested on three groups of subjects: healthy subjects; non-medicated hypertensive subjects with metabolic syndrome; and subjects with essential hypertension. Four different excitations of RR were used: bicycling exercise; tilt with breathing 0.1 and 0.33 Hz; and deep breathing. Linear dynamic feedback model of QT/RR coupling was supposed at the...
Obesity is associated with haemodynamic overload. In addition to the increased preload, left ventricular (LV) afterload is also elevated in obese individuals; an increased LV mass can alter LV filling indexes. End-systolic pressure-volume relation (ESPVR) is relatively load independent and sensitive to changes in LV contractility. In this paper, end-systole ventricular contractility Ees was determined...
We present a practical, systematical method for the evaluation of the soft error rate (SER) of microelectronic devices. Existing methodologies, practices and tools are integrated in a common approach while highlighting the need for specific data or tools. The showcased method is particularly adapted for evaluating the SER of very complex microelectronic devices by engineers confronted to increasingly...
For several decades, the output from semiconductor manufacturers has been high volume products with process optimisation being continued throughout the lifetime of the product to ensure a satisfactory yield. However, product lifetimes are continually shrinking to keep pace with market demands. Furthermore there is an increase in dasiafoundrypsila business where product volumes are low; consequently...
According to numbers of music cognitive experiments, moods or emotions in music could be categorical. Since mood classifications are commonly used to structure the large collections of music available on the Web, automatic discrimination between mood taxonomy of Chinese traditional music and Western classical music would be a valuable addition to music information retrieval (MIR) systems. In this...
Choosing the right test cases is an important task in software development due to high costs of software testing as well as the significance of software failures. Therefore, evaluating the quality of test techniques and test suites may help improving test results. Benchmarking has been successfully applied to various domains such as database performance. However, the difficulty in benchmarking test...
