• Advantages of the boundary element method and meshless approaches are inherited in hybrid MDDM to deal with crack problems. Cracked Reissner's plate non homogenous media is investigated by first time. High accurate/convergent solutions using Chebyshev polynomials can be obtained . Growing applications non-homogenous engineering structures require application powerful computational tools. A no...

Geometric modelling of several intricate and complex structures such as trees, mountains, clouds, ferns, geographic topography, coastlines is challenging in computer graphics. Traditional splines astrigonometric, polynomial, exponential, rational fail to simulate this significant class structures, which are highly irregular nature. For purpose, research develops a novel cutting-edgemethod for s...

We analyse the properties of a semi-Lagrangian scheme for the approximation of the Mean Curvature Motion (MCM). This approximation is obtained by coupling a stochastic method for the approximation of characteristics (to be understood in a generalized sense) with a local interpolation. The main features of the scheme are that it can handle degeneracies, it is explicit and it allows for large tim...

A direction map or an orientation field is widely used in automatic fingerprint verification and recognition systems. In most existing methods, the block-wise orientation field is computed from the squared gradients. Since a fingerprint image can contain areas that may be smeared or scarcely distributed, faulty orientations can be produced during the process of orientation field estimation. In ...

We prove an interpolation formula for ``semi-cartesian products'' and use it to study several constructions of auxiliary functions. We get in this way a criterion for the values of the exponential map of an elliptic curve E defined over Q. It reduces the analogue of Schanuel's conjecture for the elliptic logarithms of E to a statement of the form of a criterion of algebraic independence. We als...

A new method is presented for numerically capturing a moving interface of arbitrary dimension and codimension. The method is named the ‘local level set method’, since it localizes the level set method near the interface to significantly reduce the computational expense of the level set method. Following the framework of the level set method, an interface is implicitly represented as the zero le...

This report presents an implementation of a stable height-field fluid solver on non-uniform quadtree grids. It build upon the well known techniques of height field representation of the fluid volume, semi-Lagrangian advection, upwind differencing in the discretized representation and adaptive quadtree grids for faster calculations. A novel contribution is the applications of certain concepts an...

Hidden Markov Model is a popular statisical method that is used in continious and discrete speech recognition. The probability density function of observation vectors in each state is estimated with discrete density or continious density modeling. The performance (in correct word recognition rate) of continious density is higher than discrete density HMM, but its computation complexity is very ...

Automatic parking path optimization is a key point for automatic parking. However, it difficult to obtain the smooth, accurate and optimal by using traditional algorithms. So, based on model cubic spline interpolation, an improved immune moth flame algorithm proposed intelligent vehicles. Firstly, enhance global performance, interpolation designed shortest as target. Secondly, (IIMFO) mechanism...
