Semi-continuous data comes from a distribution that is mixture of the point mass at zero and continuous with support on positive real line. Such appear in several real-life situations like blind signal separation problems, modeling loss finance insurance, sales consumer goods, daily precipitation data, to name few. In this paper, we present novel algorithm estimate density function for semi-con...

In this paper we propose the use of a continuous data assimilation algorithm for miscible flow models in porous medium. absence initial conditions model, observed sparse measurements are used to generate an approximation true solution. Under certain assumption and their incorporation into it can be shown that resulting approximate solution converges at exponential rate as time progresses. Vario...

Abstract Nowadays, the scale of various graphs soars rapidly, which imposes a serious challenge to develop processing and analytic algorithms. Among them, graph pattern matching is one most primitive tasks that find wide spectrum applications, performance yet often affected by size dynamicity graphs. In order handle large dynamic graphs, incremental proposed avoid re-computing matches patterns ...

Continuous welded turnouts are important for CWR track through the railway station. According to equivalent resistance and non-linear theories and the principle of force diagram, a new method of theoretical calculation for continuous welded turnouts was developed. The continuous welded turnouts designed and installed according to the new theory behaved fairly well. The data collected on sites b...
