We present two methods for generating a segment of circular arc by the vector valued continued fractions. Based on this method we construct a parametric rational arc spline that is GC〓 continuity. By adjusting the given tangent vector, this parametric rational arc spline also has convexity preserving property and monotonicity preserving property.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
