We propose a simple level set method for the Dirichlet k-partition problem which aims to partition an open domain into K different subdomains as minimize sum of smallest eigenvalue Laplace operator in each subdomain. first formulate nested minimization functional function and eigenfunction defined As approximation, we simply replace by so that can then be converted single problem. apply standar...

Since the seminal work of Idelsohn, O\~nate and Del-Pin (2004), Particle Finite Element Method (PFEM) has relied on a Delaunay triangulation Alpha--Shape (AS) algorithm in remeshing process. This approach guarantees good quality Lagrangian mesh, but introduces list shortcomings that demand geometrical treatments tailored to each problem. In order improve process PFEM, this proposes use Level--S...

Here in this article, a hybrid MCDM method on the Pythagorean fuzzy-environment is presented. This based Fuzzy Method Removal Effects of Criterion (PF-MEREC) and Stepwise Weight Assessment Ratio Analysis (SWARA) approaches. Here, objective subjective weights are assessed by PF-MEREC, SWARA model preference order ranking various alternatives done through Complex Proportional (COPRAS) framework f...

Abstract Aiming at the problem of multi-view high-resolution range profile (HRRP) target recognition under open set conditions, we proposed an method based on joint sparse representation (JSR), which solves low rate traditional methods conditions. This is applied to background radar single-station observation. JSR used solve reconstruction error HRRP by over-complete dictionary, while extreme v...
