A method combining features of front-tracking methods and fixed-domain methods is presented to model dendritic solidification of pure materials. To explicitly track the interface growth and shape of the solidifying crystals, a fronttracking approach based on the level set method is implemented. To easily model the heat and momentum transport, a fixed-domain method is implemented assuming a diff...

Since its introduction, the level set method has become the favorite technique for capturing and tracking moving interfaces, and found applications in a wide variety of scientific fields. In this paper we present efficient data structures and algorithms for tracking dynamic interfaces through the level set method. Several approaches which address both computational and memory requirements have ...

In this study, to improve the accuracy of path tracking in intelligent vehicles, we propose an vehicle path-tracking control method based on improved model predictive (MPC) combined with hybrid proportional-integral-derivative (PID) theory. lateral control, a constraint side deflection front wheel is added traditional MPC and relaxation factor introduced stability for driving stability. longitu...

Conventional breeding has produced low levels of yield increase in lentils (Lens culinaris ssp. Medik.) recent decades. As hybrids have led to large increases other crops, we examined the possibility using lentils. In 52 between Australian commercial cultivars and lines from a global collection cultivated wild accessions, found 15 had seed hybrid vigor, with better parent heterosis (BPH) gains ...

A numerical model for corrosion pit propagation under mechanical loading is presented. The level set method used front tracking and also enables the domain to be split into a solid domain. In diffusion of atoms originating from dissolution process occurring at simulated. capable automatically capturing lacy cover formation due inclusion activation control, passivation. static equilibrium solved...

A hybrid system is a dynamical system whose behavior exhibits both discrete and continuous change. A hybrid automaton is a mathematical model for hybrid systems, which combines, in a single formalism, automaton transitions for capturing discrete change with di erential equations for capturing continuous change. In this survey, we demonstrate symbolic algorithms for the veri cation and controlle...
