A numerical approach to solve eighth order boundary value problems by Haar wavelet collocation method

In this paper a robust and accurate algorithm based on Haar wavelet collocation method (HWCM) is proposed for solving eighth order boundary value problems. We used the Haar direct method for calculating multiple integrals of Haar functions. To illustrate the efficiency and accuracy of the concerned method, few examples are considered which arise in the mathematical modeling of fluid dynamics an...

A New Approach to Solve Multiple Objective Programming Problems

Multiple Objective Programming (MOP) problems have become famous among many researchers due to more practical and realistic implementations. There have been a lot of methods proposed especially during the past four decades. In this paper, we develop a new algorithm based on a new approach to solve MOP problems by starting from a utopian point (which is usually infeasible) and moving towards the...

A New Meshless Method to Solve Boundary-value Problems

This paper presents a new family of meshless methods for the solution of boundary-value problems. In the h-p cloud method, the solution space is composed of radial basis functions associated with a set of nodes arbitrarily placed in the domain. The paper describes the construction of the h-p cloud functions using a signed partition of unity and how h, p or h-p reenements can be implemented with...

A New Method to Solve Singularity Problems in Covariance Matrices

Due to the dependency structure, most of the covariance matrix faces with the singularity problem. There are several methods to overcome this challenge. The most well-known ones are the eigen-value, singular value, and cholesky decompositions. In this paper, we develop a new method to deal with the singularity problem while preserving the covariance structure of the original matrix and compare ...
