Blast furnace gas (BFG) system of steel enterprise generally accompanies with multi-dimension and nonlinear features. It's a hard assignment for energy scheduling operators to make real-time scheduling decision when monitoring such system. In this study, a novel dimensionality reduction method named Space Direction Neighborhood Preserving Embedding (SDNPE) is proposed for the BFG system monitoring...
With the increasing use of medical human implant devices, wearable equipment, and other microelectronic systems, the wireless energy supply for these device or system plays a very important role in their applications. This paper presents a wireless energy transmission system based on magnetic coupling resonance technology for implanted devices. The system consists of two parts: a source ( in vitro)...
The paper describes problems with EMC of monitoring instrument in 1000kV gas insulated switchgear (GIS), due to transient enclosure voltage (TEV) produced during disconnector switching. Measuring method of TEV has been studied, including the choice of a reference ground point, the discussing about unique of scalar potential difference, and the method to eliminate the impact of magnetic field. A measuring...
Petroleum exploration and production in the Yellow River Delta (YRD) can lead to human impacts on the unique YRD wetland ecosystems. There is a strong need for scientific information on long-term ecosystem response to disturbances in YRD and the factors that affect the spatial and temporal pattern of vegetation recovery. High spatial resolution remote sensing images have been successfully used to...
Stoichiometric coefficient and model wastewater characterisation have a wide range in ASM1 model. In this study, COD is based on oxygen utilization rating method to characterise the soluble and particulate fractions. With biological respiration measurement, sensitive indicators of water parameters were measured, and satisfied simulation results was achieved. For example in Handan East Wastewater Treatment...
A wide range of applications have started to use Wireless Sensor Network (WSN) as an information collection and monitoring tool. Reliable and accurate performance of sensor nodes is necessary in critical applications. For characteristics of the WSN data stream environment, the limitations of conventional principal component analysis (PCA) method which depend on the fixed model in practical application...
From the perspective of legacy systems of Ningxia public business information services platforms involved, proposed SOA Legacy System integration framework based on web service. At the same time, Legacy System is divided into different categories according to their characteristics. We provide web service wrap approaches for different categories of Legacy System. It is an important role in our next...
In some high-cost industrial field, in order to make image processing technology make up for deficiencies in existing control methods and also have a high economy, this paper presents a smart elevator door control system based on image processing technology. Select atmega32 as the main control chip and ov7620 as image acquisition chip. Design plans to resolve the defects of 8-bit microcontroller in...
Reprogrammability is essential to achieve flexible wireless sensor networks (WSNs) that have already been deployed in field and in use. In this paper, we present a novel CFSM-based reprogramming scheme (CRS) for implementing dynamic tasking in WSNs. In CRS, a lightweight Script Interpreter platform is installed to each sensor node. New applications are represented by task scripts that are essentially...
This paper presents a query optimization method for continuous data gathering in sensor networks. The method is based on a coarse-grain data collection approach by using the setting of thresholds and the analysis on the content to be sent over the network. In particular, the paper concentrates on the situation where phenomena under monitoring appear a periodical feature. An initiative data model is...
