Wind turbine condition monitoring and fault warning has important practical value to reduce maintenance costs, improve operational efficiency and reliability. In this paper, the characteristic parameters of SCADA system monitoring, based on the principle of similarity modeling techniques, through reasonable...

Water ecological carrying capacity of basin is important basis to whether coordinated development for basin resources, environmental and economic society, is important means to impetus sustainable development of water ecological environment and social economy. Take Tieling section of Liao River as an...

Determining the vertical wheel-rail force by measuring rail displacement is approved to be feasible in this paper. Wheel-rail force data is collected following the common way firstly, i.e. strain gauge is pasted on the rail to measure the strain. During the test, different vehicle running speeds through...

Starting from the theoretical research, the paper conducts a deep investigation and analysis of the actual development of the Baicheng Industrial Park. With the method system of qualitative and quantitative analysis, the...

Changchun Jingyuetan National Scenic Spot is a sophisticated ecosystem, to explicit the functions and values of ecological products, ecological process, and to offer information for decision makers, a range of appropriate ecological assessment methods: opportunity cost approach, cost analysis, human...

Electron mobilities limited by surface roughness scattering (SRS) in GaN nanowire have been investigated theoretically. The mobility found to be sensitive to the nanowire radius and electron density. Results show that the larger radius nanowires exhibit considerably higher mobility than smaller radius....

The sodium metavanadate samples are digested in hydrochloric acid, and the content of matrix element sodium is directly measured by inductively coupled plasma atomic emission spectrometry (ICP-OES). The optimum dilution ratio is disposable obtained by optimizing the weight of the sample and the volume...

A traffic states detection method is proposed to represent the road traffic conditions accurately and reduce labor intensive monitoring work in this paper. The edge of image, which is named as edge characteristic, is applied to describe the number of vehicles running on the road, and the average density...

In order to realize underwater automatic welding in deep water environment, an automatic welding equipment, which is composed of truss structure, welding mechanism and mobile walking mechanism was designed and tested in the recent research. The bent fatigue strength check was carried on the driving part...

Microfluidic driving and controlling techniques are fundamental and important in microfluidic applications. Traditional reagent driving systems of microfluidic chips such as syringe pump and piezoelectric actuator have their inherent shortcomings. Syringe pumpis easy to deformation and screw motion is...

In this paper, the rear drive axle house of Dong Fang Hong 40 tractor was selected as the research object, through Finite Element Analysis by ANSYS Workbench, critical sections and conditions were obtained. Based on results by FEA, multi-objective fuzzy reliability robustness design model of rear drive...

In this paper, the design development of a new type of self-balance obstacle car, it can climb over obstacles, across the gully. The car is on left and right wheels independently driven, through advanced microprocessor. The inclination sensor in control system and the mechanical body device to control...

Drive system of generator is an important part of wind turbine, once the fault occurs it will cause huge economic losses. For this reason, in this paper, a fault diagnosis method is proposed for generator rolling bearings, it combined with wavelet packet and support vector machine. Acquisition of wind...

With the implementation of new pattern urbanization, the smart city construction in China is gradually out of the stage of project and conception, and switching to the stage of exploration and practice. Intelligent property is the important component of smart city. With recent years’ development, property...

Land intensive use is essentially the relationship between land input and output, which means to get the highest output with the least input. The evaluation of land intensive use level is a vital content of urban land management, which can help to provide scientific basis for the governments' decision-making...

An optimization scheme of the leakage current reduction (LCR) for SRAM design has been proposed in this letter. By choosing the enabling signals for the LCR circuits intentionally, it can be deduced theoretically that there exists an optimal design option for the LCR technique application under the premise...
