Stroke and heart disease are among the most com-mon outcomes of hypertension. Each year, disease, stroke, other cardiovascular disorders claim lives more than 877,500 people in United States, making them first fifth leading causes death, so being able to pre- dict early helps save lives. A lot research has been done reach this goal. Machine learning models mostly used for purpose. For time stud...

The existing forward collision warning (FCW) systems that adopt kinematic or perceptual parameters have some drawbacks in the performance because of poor adaptability to users ineffectiveness warnings. To solve problems adaptability, several FCW models been proposed based on algorithms (machine learning, deep learning). However, there is a lack consideration for multi-staged avoid an abrupt may...
