The method of Brownian configuration fields (BCF) is a promising multi-scale approach for the simulationof viscoelastic fluids, however, it is a computationally expensive method, which restricts its application in complex scenarios. Therefore, it is of great importance to optimize the parallel implementation in order to improve computational efficiency. In this paper we propose a hybrid decomposition...
Cultured finfish are an important source of animal protein worldwide and the Food and Agriculture Organization (FAO) reported that over half of the world's supply of fish and shellfish is now from aquaculture. This chapter provides an overview of the fish immune system and the infectious diseases of fish (bacterial, viral, parasitic, and fungal). It discusses the adaptive immune system of fish which...
The superior performance of polarization sensitive array (PSA) over the single polarization array is achieved by doubling system facilities and more computational load, which limits its applications in the radar field. The alternate polarization array (APA) can reduce this problem but it still has results in the obvious fencing lobe problem. A novel design of random polarization array (RPA) is presented...
Using super resolution direction of arrival (DOA) estimation algorithm is an effective method for passive radar seeker (PRS) to antagonize non-coherent radar decoy. A novel DOA estimation algorithm is proposed to estimate the two-dimensional (2-D) arrival angles of multisource by using a uniformly circular array (UCA) of crossed dipoles. By exploiting the polarization diversity of the signals, PRS...
As an effective reduced-dimension space time adaptive processing (STAP) approach, subarray technique is widely used in practice. However, it is hard to determine how many subarrays are necessary and what shape should they have. In this paper, a generalized form of STAP processing for arbitrary array is established. Then the subarray technique for STAP is discussed. In order to determine the optimum...
The optimal multiple linear constraint minimal variance (LCMV) beamformer is presented under multiple desired signals case. The theoretical solutions of the optimal weighted vector and maximum signal-to-interference-plus-noise-ratio (SINR) are derived by using variable substitution method. Simulation results show that the algorithm is superior to the traditional LCMV approach in the SINR, computational...
Subarray technology is an effective solution to the “conflict of sum and difference” in a large array radar. However, the optimal subarray partition method is a difficult problem both in the theoretic and practices. By exploring the advantage of genetic algorithm, a method, to optimize the subarray configuration in monopulse application, is proposed in this paper. The innovative method is subtly designed...
Using super resolution direction of arrival (DOA) estimation algorithm to reduce the resolution angle is an effective method for passive radar seeker (PRS) to antagonize noncoherent radar decoy. To make use of the polarization information of radar and decoy signals, the diversely polarization array (DPA) is applied to PRS direction finding systems. A comparison is made between the resolution angles...
Development of data mining application is very important for the telecommunication enterprise, which is a typical data-intensive industry. Customer segmentation can help analyze customer composition accurately and promote the quality of service and marketing. Using K-means clustering and the commercial automatic data mining tool KXEN, the paper proposes a resolution of customer segmentation for Changzhou...
According to the exiting issues of currently DC system insulation monitoring device, this paper developed a more comprehensive function monitoring device. The device adopted phase different of magnetic modulation detection principle. Though access to the unbalanced grounding relay, it can solve the conventional devices which unable to detect issue like: the DC system grounding simultaneity or equivalent...
Trellis Coded Modulated (TCM)-QPSK has been demonstrated as a coherent optical modulation format. For the first time its performance is compared to BPSK on four subsea segments of different lengths, showing performance benefits of up to 1.8 dB.
Today's submarine carriers are seeing double and triple digit annual growth on installed submarine cable systems and are faced with the challenge of how to cost-effectively upgrade these systems. Many of the world's markets are showing up to 100% CAGR in internet traffic, and hence submarine cables are required to expand to multiples of their initial design capacities. Since the cost of installing...
This paper did a research on the relationship between diversification strategy and analyst following. Firstly it analyzed how diversification strategy affected on analyst following in theory. And then it did an empirical study between them by two-stage least squares(2SLS), choosing 299 listed companies in Shanghai stock market from 2007 to 2009 as research samples. The result showed that the companies'...
Based on agency theory, this paper studied on the relationship between corporate governance structure and diversification strategy. Choosing 520 listed companies in Shanghai stock on December 31, 2009 as research samples, the paper did an empirical study on the impact of corporate governance structure on diversification strategy. The result showed that concentration of ownership, proportion of legal...
The various applications of polarimetric SAR data have brought to the fore questions of polarimetric calibration. Most polarimetric calibration methods based on distributed targets employed reflection symmetry assumption, which might be inconsistent with the truth due to a possible orientation angle shift, and therefore would skew the polarimetric signatures of targets. In this paper, a model incorporating...
The method of using unsaturated light-induced delayed fluorescence (DF) intensity to represent photosynthetic capacity (PhC) has been testified experimentally by our research group. For further perfection of the proposed method, in this research, a four-segment DF light response curve model was presented, the relationship between saturated and unsaturated light-induced DF intensity was investigated,...
Accounting standards is a kind of incomplete contract and its residual control right belongs to enterprises' stakeholders. Stakeholders participating in accounting policy choice (SPAPC) is a method of distribution in residual control right of accounting standards. The strategy choice among stakeholders is a process of repeated game. Stakeholders choose strategy on the basis of the present value of...
Land cover is a critical variable that links many aspects of the physical and human environments. In the present study, the post-classification comparison method is employed for detecting land use/land cover changes (LUCC) of Dongjiang River basin during the period of 2001 - 2008 mainly based on MODIS 250 m Enhanced Vegetation Index (EVI) time series data, and in addition MODIS land surface temperature...
It is of great significance to reduce the consumption of fuel oil for pulverized coal fired boilers in China even throughout the world. Minimal-oil ignition technology is an effective solution to save fuel oil. The principal, system components and industrial applications of the minimal-oil ignition technology are introduced in this paper. Numerical simulation data shows that the newly designed coal...
This paper presents a modeling method for the small-signal frequency response analysis of a monolithic power integrated circuit (IC).
