With the rapid development of indoor positioning and intelligent robotics technologies, fine-grained location services are approaching. The existing 3D information acquisition expression methods furniture complex inefficient cannot meet needs high-precision services. Therefore, this paper proposed a parameterized crowdsourcing method for data based on model library. This used set classification...

In this paper, we consider the inhomogeneous time-fractional nonlinear Fisher equation with three known boundary conditions. We first apply a modified Homotopy perturbation method for translating the proposed problem to a set of linear problems. Then we use the separation variables  method to solve obtained problems. In examples, we illustrate that by right choice of source term in the modified...

We investigate an ultraweak variational formulation for (parameterized) linear differential-algebraic equations with respect to the time variable which yields optimally stable system. This is used within a Petrov-Galerkin method derive certified detailed discretization provides approximate solution in setting as well model reduction spirit of Reduced Basis Method. A computable sharp error bound...

We consider the two-echelon location-routing problem (2ELRP), a well-known problem in freight distribution arising when establishing a two-level transport system with limited capacities. The problem is a generalization of the NP-hard location routing problem (LRP), involving strategic (location), tactical (allocation) and operational (routing) decisions at the same time. We present a variable n...

In the present work, a hybrid of Fourier transform and homotopy perturbation method is developed for solving the non-homogeneous partial differential equations with variable coefficients. The Fourier transform is employed with combination of homotopy perturbation method (HPM), the so called Fourier transform homotopy perturbation method (FTHPM) to solve the partial differential equations. The c...
