Convergence Analysis for Operator Splitting Methods
We analyze the order of convergence for operator splitting methods applied to conservation laws with stii source terms. We suppose that the source term q(u) is dissipative. It is proved that the L 1 error introduced by the time-splitting can be bounded by O((tkq(u 0)k L 1 (R)), which is an improvement of the O(Qt) upper bound, where t is the splitting time step, Q is the Lipschitz constant of q...
متن کاملAnalysis of Air Pollution
This research paper is an attempt towards analyzing real time air pollution data collected by PAQS sensor devices from some key locations in Bangalore. Air pollution in most of the metropolitan cities in India is turning out to be a major threat to our environment and hazardous to our health. Many infections and diseases related to lungs and throat are caused by the polluted air we breathe. The...
متن کاملNonlinear modelling of air pollution time series
An analysis of predictability of a nonlinear and nonstationary ozone time series is provided. For rigour, the DVS analysis is first undertaken to detect and measure inherent nonlinearity of the data. Based upon this, neural and linear adaptive predictors are compared on this time series for various filter orders, hence indicating the embedding dimension. Simulation results confirm the analysis ...
متن کاملOperator Splitting Method for Coupled Problems: Transport and Maxwell Equations
In this article a new approach is considered for implementing operator splitting methods for transport problems, influenced by electric fields. Our motivation came to model PE-CVD (plasma-enhanced chemical vapor deposition) processes, means the flow of species to a gasphase, which are influenced by an electric field. Such a field we can model by wave equations. The main contributions are to imp...
متن کاملSplitting schemes for unsteady problems involving the grad-div operator
In this paper we consider various splitting schemes for unsteady problems containing the grad-div operator. The fully implicit discretization of such problems would yield at each time step a linear problem that couples all components of the solution vector. In this paper we discuss various possibilities to decouple the equations for the different components that result in unconditionally stable...
