This paper begins with exploratory research for designing and planning Agricultural Supply Chain Traceability System (ASCTS), which can provides a powerful technical support for timely tracing and finding the link where a food safety problem happens in the agricultural supply chain. This paper divides into 3 sections: the first to briefly introduce the concept relevant to ASCTS and significance of...
Isatin, an endogenous compound existent in many organisms, shows a wide range of biological activities. In this paper, we like to report the design and synthesis of several isatin derivatives through the acetalization, N-Alkylation, Microwave-asistant Heck coupling reaction and so on. Among those compounds, (E)-1-(4-chlorobenzyl)-5-styryl-indoline-2-carbonyl-3, 3-(ethylenedioxy) dione and (E)-1-(4-chlorob-enzyl)-5-styrylindoline-2,...
Carrier aggregation technique plays a significant role in LTE-A to meet the need of higher data rate, it applies a number of frequency bands to transmit signals and therefore there is a promising research arising that it is indispensable to study the characteristics of the signal at different frequencies at a receiver, in order to make the receiving equipment adjusted to the discrepancy of the receiving...
Strengthening the competition ability is an urgent mission for China's air transport industry to survive in the market. In order to find the way of improving the industry competition ability, influencing factors of air transport industry competition ability were analyzed. The connotation of air transport product was defined, and its characteristics and competitive performance level were dissected,...
Modern cars are integrated with more and more electronic devices, controllers, sensors, actuators, bring more convenience, comfort and safety to the driver. Therefore, the active safety, connectivity, intelligence has become a main direction of research and development on the future cars, and these are based on the complex communication system established inside and outside the vehicle, which constitute...
To meet the special requirements on micro-climate raised by the greenhouse in Northeast China, we develop a WSN-based greenhouse environment monitoring system. We decrease the power consumption of nodes, reduce the complexity of system development and simplify the deployment of nodes by dormancy mechanism, single-hop transmission, and on-demand deployment. Gateway node transmits the sensor data to...
Idle listening is one of the most main sources of energy waste in WSN and many low power protocols(LPPs) have been proposed based on duty cycling to reduce this cost. The research of LPPs can effectively save energy and prolong network lifetime. Therefore, a thorough experimental evaluation system of LPPs is mandatory. This motivated us to build a testbed — TELPP that automates LPPs evaluation by...
This paper targets the identification of faulty sensor nodes, which is one of the most important sources of faults in wireless sensor networks. To explore an effectual technique for node self detection, a new algorithm, Node Self Detection by History data and Neighbors (NDHN) is proposed in this paper. This algorithm collects the characteristics of the nodes to compute the biases through historical...
Accurate fault prediction or remaining useful life (RUL) estimation can obviously reduce cost of maintenance and decrease the probability of accidents so as to improve the performance of the system test and maintenance. At the same time, it is difficult to apply the model-based methods for fault prediction in most applications for complex systems. Due to continuously improving of automation, increasing...
For mobile communication traffic, an accurate prediction result plays an important role in network management, capacity planning, traffic congestion control, channel equalization, etc. This paper proposes a clustered complex echo state network for mobile communication traffic forecasting with prior knowledge. In order to reflect some learning mechanisms of real world organization, various complexities...
A Cloud may be seen as a type of flexible computing infrastructure consisting of many compute nodes, where resizable computing capacities can be provided to different customers. To fully harness the power of the Cloud, efficient data management is needed to handle huge volumes of data and support a large number of concurrent end users. To achieve that, a scalable and high-throughput indexing scheme...
The research status of magnetizing model of TA core is analyzed and summarized. Five kinds of magnetizing models are illustrated briefly. Magnetizing model of solid core based on Jiles-Atherton theory is deeply analyzed. And the simulation of dynamic hysteresis loop is realized. Combined with the related theoretical derivation of air gapped core, the magnetizing model based on Jiles-Atherton theory...
The failure of venous grafts that are placed in the arterial circulation is a significant clinical problem that should be addressed by researchers. One factor that is believed to play a role in causing these failures is changes in the wall strain environment. In this study we present a novel approach to recording wall strain in a murine model and demonstrate our ability to differentiate strains between...
Real-time monitoring data mining has been a necessary means of improving operational efficiency, economic safety and fault detection of power plant. Based on the data mining arithmetic of interactive association rules and taken full advantage of the association characteristics of real-time test-spot data during the power steam turbine run, the principle of mining quantificational association rule...
Multimedia services are most attractive services for users in wireless networks. And the QoE (Quality of Experience) is fairly significance for both operators and users. However, currently the QoE metrics and related data collected from mobile devices haven't been ascertained, and the QoE assessment system is one-sided. Besides, architecture to measure such QoE metrics is deficient. To improve it,...
In recent years, the low power technology has brought up a great impact on portable electronic devices. As for the mobile device, the low-power circuit design becomes the primary issue. At present, TFT LCD has been widely used in handheld mobile devices. In terms of the overall system power consumption, TFT LCD power consumes 20%~45% of the total system power depletion due to different applications...
