چکیده

In this paper, we propose a deployment algorithm for mobile sensor networks, based on fluid dynamics in three-dimensional circumstance. In our algorithm, the entire wireless sensor network is viewed as a fluid body while nodes as charged particles. In the algorithm, nodes tend to spread out into the deployment area automatically, driven by the interaction force between nodes and nodes, nodes and obstacles, as well as nodes and boundaries. We achieve the desirable properties of self-adaption, robustness and simpleness, so that it is especially applicable to deployment in unknown environments. The performance indices of coverage and uniformity are evaluated by simulation. Simultaneously, we utilize digital satellite map nearby Midway Islands sea area to check the deployment effect in simulation, and the results show that our approach can guarantee a desired level of coverage. Moreover, the application of digital satellite map also provides a new approach for studying deployment of virtual reality in sensor networks.

Numerical simulation of the fluid dynamics in a 3D spherical model of partially liquefied vitreous due to eye movements under planar interface conditions

Partially liquefied vitreous humor is a common physical and biochemical degenerative change in vitreous body which the liquid component gets separated from collagen fiber network and leads to form a region of liquefaction. The main objective of this research is to investigate how the oscillatory motions influence flow dynamics of partial vitreous liquefaction (PVL). So far computational fluid d...

Design of a Novel Framework to Control Nonlinear Affine Systems Based on Fast Terminal Sliding-Mode Controller

In this paper, a novel approach for finite-time stabilization of uncertain affine systems is proposed. In the proposed approach, a fast terminal sliding mode (FTSM) controller is designed, based on the input-output feedback linearization of the nonlinear system with considering its internal dynamics. One of the main advantages of the proposed approach is that only the outputs and external state...

Intelligent identification of vehicle’s dynamics based on local model network

This paper proposes an intelligent approach for dynamic identification of the vehicles. The proposed approach is based on the data-driven identification and uses a high-performance local model network (LMN) for estimation of the vehicle’s longitudinal velocity, lateral acceleration and yaw rate. The proposed LMN requires no pre-defined standard vehicle model and uses measurement data to identif...

A New Lagrangian-eulerian Shell-fluid Coupling Algorithm Based on Level Sets

We propose a computational method for the coupled simulation of a compressible flow interacting with a thin-shell structure undergoing large deformations. An Eulerian finite volume formulation is adopted for the fluid and a Lagrangian formulation based on subdivision finite elements is adopted for the shell response. The coupling between the fluid and the solid response is achieved via a novel ...
