In the traffic system with flow guidance, travelers can choose their paths according to both guidance information and their experience. In this paper, based on the relationship between the effects of traffic guidance and the construction cost, the optimization plan is established as a bi-level program. The objective function at the upper level is defined as the total travel time on the network, plus...

It can get the data of hydraulic system for construction machinery and equipment by various type sensors. The model of hydraulic system for construction machinery and equipment condition measurement and fault diagnoses...
Enterprise Service Bus (ESB) is a kind of SOA-based software infrastructure for business application integration. In this paper, it firstly analyses the current state of enterprise integration and the drawbacks of the hub-and-spoke topology, then it introduces a new design approach for EAI base on ESB called EAI-ESB. The EAI-ESB approach which contains Message construction, Messaging channels, Listener,...
Clients can exchange data with embedded device where Web server is transplanted. In order to observe the state of the device and display it in the form of dynamic history curve, this paper has adopted two methods to get the real-time data of the embedded device and display the curve. One uses JavaScript cooperating with VML (Vector Markup Language), the other uses Applet. The two methods both have...
Based on the input-output data , a multiple-model modeling method is suggested for the complex nonlinear system. Firstly, fuzzy partition is employed to on-line clustering for the input-output data; and then, the least-squares (LS) algorithm is employed to construct the local model for each clustering, and the parameter of each local model is updated by the new data. The proposed algorithm takes advantage...
The time parameter about emergency decision-making problems is the primary optimizational object. Evolutionary strategy (ES) can solve the problems of continuous parameter optimization, and is an effective way of solving complex optimizational problems. Therefore, in the paper dual-gene variation hybrid evolution strategy algorithm (μ +λ +κ ) - ES is used to construct the fire emergency decision-making...
Singular Value Decomposition (SVD) Filtering is one seismic data processing technique which uses the lateral coherence difference of the seismic wave to achieve wavefield separation and denoising. As the differences of propagation characteristics, apparent velocity and coherence in seismic signals, transformation of the valid signals may be transformed into those with better coherence by some mathematic...
The H-infinity mixed sensitivity tracking control method is applied to the vibration control of high-order flexible structures and a method for the choice of the mixed sensitivity weighting matrix is put forward. A MIMO (multi-input multi-output) control model of a vibration system is established which induced model uncertainties via the H-infinity control theory and the mixed sensitivity design method...
The problem of semi-supervised dimensionality reduction with kernels called KS2DR is considered for semi-supervised learning. In this setting, domain knowledge in the form of pair constraints is adopted to specify whether pairs of instances belong to the same class or not. KS2DR can project the samples data onto a set of `useful' features and preserve the structure of unlabeled samples data as well...
This paper proposes hybrid unscented particle filter for integrated navigation system of vehicle which have characteristics of long-time moving and frequent changes in dynamic performance and different non-linear and non-Gauss characteristics. The algorithm combined with zero velocity updates method (ZUPT) and effectively reduced the error of different vehicle's dynamic characteristics based on the...
Transfer functions of n zones and arbitrary ki on the time-sharing working mode of the multi-zone space crystal growth furnace made in china were constructed. Taking two and three zones with equal time-sharing mode for example, the static characteristics while s = 0 and transient properties while ω = 2π were offered and Comparisons with zero-order holder were made. At last, conclusions that the time-sharing...
An algorithm of target tracking based on adaptive waveform design was proposed with the help of Doppler estimation theory. According to the analysis of the ambiguity function for liner frequency modulation signal, a model between ambiguity function of the signal and Cramer-Rao bound of time and frequency delay was built. This paper realized the target tracking by adjusting the frequency width and...

Most parts of rotating machine rotate cyclically when the machine fails for some reason, and the vibration signal of rotating machine often has the cyclostation character. Aiming at this feature, Degree of Cyclostation(DCS) was presented to analyze the fault trend of rotating machine in this paper. DCS was constructed by the comparison between third-order non-stationary cyclic moments and stationary...
For multilayer sandstone reservoir 1, high permeability water passage would be formed between oil well and water well at the later stage of water drive. This caused the injected water circulation with no or low efficiency and thus decreased the production of oil wells. In order to improve the effect of water drive, measures of profile control and/or water shutoff must be taken. The key problem is...
An optimal planned route is a foundation of safe and economical navigation. This paper proposes a method for the shortest distance routing in a chart based on testing a spatial relation of a linear route segment and an obstacle area. Firstly, safety contour traces are traced and obstacle areas are acquired automatically. Then possible optimum paths circumambulating an obstacle are searched automatically...
Electric propulsion devices have been used widely in space flight mission for its superior performance. As a kind of electromagnetic thruster, the parallel-plate pulsed plasma thruster (PPT) as well as its operation process is theoretically analyzed and discussed. Based on the electromechanical model of PPT-an idealized, quasi-steady, analytic model including the ablated mass process of Teflon, an...
IEEE-1394b is a high speed data bus, which is widely adopted in various commercial products. Its isochronous data transfer is well suited for time critical data transfer, such as video and audio.

The signal in reality is mostly non-stationary signal. In current, this type of signal analysis focus on time-frequency (or time scale) domain, which has also made a series of results. This paper presents a reversible transform method based on a bit of time series from another point. Using this method, we analyze non-stationary broadband noise signal according to the different characteristics between...
The compression effect of existing lossless compression algorithm for JPEG file is poor.
