This paper presents a two-gain Iterative Learning Control (ILC) design for nonlinear discrete systems with time delays in state. The convergence of the proposed ILC rule with sufficient condition is derived based on a kind of two-dimensional (2-D) linear inequalities. The proposed ILC rule is able to guarantee convergence of the learning process against fixed iterative initial errors. An example is...
The traditional hardware description languages (VHDL and Verilog) is not suitable for system-level modeling and Hardware Software Codesign, while the SystemC language is more suitable than the traditional HDL language for system-level modeling. This paper describes the packet processing engine(PPE) characteristics of XDNP network processor, analyze the advantage of system-level modeling in SystemC...
Carbon emissions, carbon sinks and carbon flux of urban ecosystem in Xianning over the last decade were calculated. The results show ed that annual carbon flux steadily increased from 1, 570, 411 tons in 1996 to 7, 514, 089 tons in 2008, especially after 2005 with the annual average growth rate of 51.1%. Carbon emissions from industry accounted for 79.6% carbon emissions in 1996, 94.5% in 2008, resulting...
The study is to validate the transmission route of rabbit meridian and the organizational structure of meridian in cellular level. The water solution of Na2H32PO4 (18.5MBq/0.25ml) was injected into “waiguan”, “neiguan”, “yang gu”, “taixi” acupoint according to human meridian. The transmission route and the tissue structure of rabbit meridian were detected with 32P whole and light microscopic autoradiography...
At present, each industry has its own database system. Yet, the overall performance of the business systems is falling, with the increase of running time and the rapid growth of the amount of data. Data rapid finding program was designed in this paper, table partition and index partition technology were used in large oracle table, and fast data retrieval was completed.
This paper presents a control method for charging a battery as well as for controlling a fuel cell in a battery-fuel cell hybrid system. Due to the slow start up time of a PEM fuel cell it must be augmented by an alternative source to meet the fluctuation of power demands. This paper presents a hybrid fuel cell and battery system to serve a load. Additionally, based on the State of Charge (SOC) of...
Some pipe lines of a nuclear power plant exists serious vibration that seriously affected the normal production safety. By the spectral analysis of measured time domain signal, the main vibration frequency of the pipe lines was obtained. The model analysis was processed with pipe stress analysis software CAESAR II. The natural frequency was found. According to the causes of pipe lines vibration, the...
The coherence optimization methods of compact polarimetric SAR interferometry (PolInSAR) are analyzed in this paper. Coherence optimization for compact PolInSAR can be performed directly in the two-dimensional observation space of the CP system without the reconstruction of the pseudo fully PolInSAR covariance matrix. The performance of different compact polarimetric modes for coherence optimization...
Readout noise of RF impedance analyzer and LCR meter are observed and analyzed with narrow bandwidth noise theory. The difference between theory analysis and actual measurement results is shown. The effect of impedance measurement format on noise is discussed at last.
The effect factors of adsorption treatment of methylene blue (MB) solution by aged-refuse were studied with static absorption method under different conditions. In the meantime, Langmuir and Freundlich isotherm equation, pseudo-first order and pseudo-second order kinetics models were fitted. The results showed: when the initial concentration of MB solution is 10mg·L−1, the best parameters as follows:...
The performance of dynamic adsorption and the effects of height of filler, MB initial concentration and flow rate on the breakthrough curves were investigated by the dynamic adsorption experiment of the filler column. The results showed: Aged-refuse can effectively adsorb MB in the water, with the increase of filler height, the breakthrough point in the curve move toward the right and the breakthrough...
To fairly allocate network bandwidth for different streams and to achieve a smooth quality between different video sequences are two key issues in multi-stream applications. In this paper, a new joint rate control scheme for multiple video streams based on game theory is proposed. We achieve a fair rate allocation in video quality between different sequences by Nash Bargaining theory under the constraints...
The designers, producers and disseminator of E-government information resource database should bear the liability to damages to the victims (users), if they provide the defective database and causes damage to others. Based on database user rights protection and promoting the development of science and culture, database product liability shall apply the principle of presumptive fault, the constituents...
We propose an new optimal routing strategy that collectively minimize the maximum ratio of betweenness to capacity in any link. The topological structure of fire emergency traffic network is studied by considering networks with a heterogeneous distribution of link capacities and with a heterogeneous transport load. At last, the theoretical derivation of the average travel time is given according to...
The central air-conditioning system which runs under the mode of fresh air mixed with return air doesn't take full advantage of the fresh air to remove air conditioning load, leading to high energy consumption and carbon emission. The calculation model for carbon emission reduction of all-fresh air operation in central air-conditioning system is proposed based on the air conditioning control strategies...
Based on the clutter statistical characteristics of fully polarimetric SAR image, this paper presents a novel method for SAR change detection based on the heterogeneous clutter model. We use spherically invariant random vectors (SIRV) distribution model to fit the urban areas of full polarimetric images. Then, the degree of evolution between the statistical characteristics of multi temporal full SAR...
An integrated beam synthesis algorithm is presented to optimize the multiple beams of variable look-angle SAR antenna. With an iterative solution scheme of improved projection matrix algorithm, the amplitude excitations (common to all beams) and the phase of such excitations (corresponding to each radiated beam) are determined simultaneously. Antenna beams are controlled by phase only in SAR system...
