Two-dimensional HP-adaptive Algorithm for Continuous Approximations of Material Data Using Space Projection

Two-dimensional HP-adaptive Algorithm for Continuous Approximations of Material Data Using Space Projection

In this paper we utilize the concept of the L and H projections used to adaptively generate a continuous approximation of an input material data in the finite element (FE) base. This approximation, along with a corresponding FE mesh, can be used as material data for FE solvers. We begin with a brief theoretical background, followed by description of the hp-adaptive algorithm adopted here to imp...

Design of Kreisselmeier Adaptive Observer using Projection Algorithm for Continuous-time Linear Fractional Order Systems

Many complex systems containing fractal structure can be described by fractional order derivative. By expressing the complex system as fractional order system (system containing fractional order derivative), system’s complex behavior can be simply described with small number of parameters. However, in order to control or identify such system containing unknown variable parameters, online parame...

Adaptive Geometric Multiscale Approximations for Intrinsically Low-dimensional Data

We consider the problem of efficiently approximating and encoding high-dimensional data sampled from a probability distribution ρ in R, that is nearly supported on a d-dimensional setM for example supported on a d-dimensional Riemannian manifold. Geometric MultiResolution Analysis (GMRA) provides a robust and computationally efficient procedure to construct low-dimensional geometric approximati...

A topology control algorithm for autonomous underwater robots in three-dimensional space using PSO

Recently, data collection from seabed by means of underwater wireless sensor networks (UWSN) has attracted considerable attention. Autonomous underwater vehicles (AUVs) are increasingly used as UWSNs in underwater missions. Events and environmental parameters in underwater regions have a stochastic nature. The target area must be covered by sensors to observe and report events. A ‘topology cont...
