The application of the multi-GPU and multi-CPU cooperation to computing large scare electromagnetic object provides a substantial acceleration in speed. In this paper, we show that cooperation of multi-GPU and multi-CPU accelerates hybrid time domain physical optics (TDPO) and time domain equivalent edge current (TDEEC), it runs 150 times faster when a single-thread executes TDPO+TDEEC. The parallel...
In this paper, an Active Disturbance Rejection Controller (ADRC) is introduced into the system named the dredger cutter motion control, aiming at achieving the cutter motor synchronous speed control precisely. Because the load power of cutter motor may changes drastically at work, it is important that the parallel drive of two cutter motors is designed to keep the system secure and ensure its reliability...
Isolator with adjustable stiffness and damping is significant for the subway floating slab track to achieve vibration isolation control in a wide frequency range. Firstly, the dynamic model of long beam floating slab tack vibration system with moving load is built. And then the HSIC (Human simulated intelligent control, HSIC) optimization algorithm is proposed based on the vertical vibration. After...
In cloud computing, load balancing is a very important performance factor. Frequent addition and removal of Virtual Machines (VMs) can cause load imbalance across Host Machines (HMs). Therefore, redistribution of VMs to different HMs needs to be performed periodically. This is called VM load rebalancing (VMrB). Existing VMrB solutions consider either balancing across HMs (inter-HM) or balancing within...
The application of Active Disturbance Rejection Controller (ADRC) in the cutter suction dredger cutter motor synchronous speed control system was presented in this paper, which aims at achieving the cutter motor synchronous speed control. It's necessary to adopt the parallel drive of two cutter motors to keep dredger secure and reliable because of the drastic change of the power of dredger cutter...
In cloud computing, an important issue is virtual machine placement (VMP), selecting the most suitable set of physical hosts for a set of virtual machines. In this paper, we present a novel solution to the VMP problem called VMPMBBO. Our scheme treats the VMP problem as a complex system, and utilizes the biogeography-based optimization (BBO) technique to optimize the virtual machine placement that...
Through analyzing the factors influencing BBD ball mill load and the measure characteristics, a BBD ball mill load measure method, based on rough set and neural networks information fusion, was proposed. A group of neural networks were constructed for material measure according to the relative reductions, which was feature-level information fusion. Then using the attribute significance determining...
