In order to study the basic discipline of road traffic flow after the accident, considering the effect of vehicle speed on the basis of traditional cellular automaton, an improved NS model is proposed. Through analyzing the urban traffic flow under the influence of accident vehicles, urban dual-lane traffic flow model under the influence of accident vehicles is constructed, namely vehicle lane-changing...
Based on fresh random challenge response authentication and key agreement, access control, priority control mechanisms, this paper puts forward a security protection communication protocol to guarantee the data transmission security of electricity acquisition terminal and the acquisition host. From the angle of attack detection, this proposed protocol was proved that can resists replay attack, counterfeit...
Magnetically controlled shape memory alloy (MSMA) which has fast response, high energy density and other excellent characteristics, have a broad application prospects as a potential intelligent sensor materials. However, the unclear correlation between the environment temperature and the sensing characteristics limits the application of MSMA in the sensor field. According to the sensing characteristics...
The real-time monitoring of status parameters, such as cell voltage and state of charge (SOC), is an important guarantee of the safety operation of the battery energy storage system (BESS). And the two-level architecture of hardware system which includes several battery management units (BMU) and the central management unit (CMU) is designed with the communication protocol and data conversion algorithm...
The hybrid energy storage system (HESS) composed of super capacitors and batteries is proposed in this paper for the power supply system of rail transmit to prevent the overtension of grid voltage caused by the braking energy. According to the power fluctuations and allocation principle, the capacity and control method of HESS are designed to achieve the voltage stabilization of the traction grid...
The paper analysis influencing factors of grain production in Heilongjiang province, using the theory of gray system model. In Heilongjiang Province, the chemical fertilizer, the per unit area yield of grain and other agricultural technology and production input factors is the main influence factors in the current and future; secondly, the comprehensive influence of agricultural natural resources...
With the SIMT execution model, GPUs can hidememory latency through massive multithreading for many applications that have regular memory access patterns. To support applications with irregular memory access patterns, cache hierarchies have been introduced to GPU architectures to capture temporal and spatial locality and mitigate the effect of irregular accesses. However, GPU caches exhibit poor efficiency...
The level of county urbanization is very important to the development of county economy. This The paper based on the data of 44 agricultural counties of old industrial base-Liaoning province to analyze the mechanism of how county urbanization acting on county economy development theoretically and empirically. The results show that: (1) on theory, county urbanization promotes the development of county...
An accurate quantitative estimation of crop chlorophyll content is of great importance for a wide range of monitoring crop grow health condition and estimating biomass, since radiative transfer model are complex caused by the nonlinear relationship between crop spectral and chlorophyll content and the uncertainties in the land surface systems, traditional inversion techniques can not satisfied with...
Heavy metal pollution of soil in the mining tailings is one of the most serious environmental problems in the world nowadays. Heavy metals may pose a long-term potential threat to ecosystems and human health. Therefore, it is significant to monitor heavy metal pollutions of soil in the mining tailings, and it become an urgent task. The goal of this research was to estimate Pb concentration in mining...
This paper studies the basic configuration of strategic human capital in innovative (R&D) teams and explores the relationship between strategic human capital and firm competitive advantages. Based on theories of human capital and the resource-based view of firms (RBV), and by using team spirit and human-capital deployment as moderating variables, the study surveys 218 high-tech SMEs in Beijing-Tianjin-Hebei...
Prediction of long intergenic non-coding RNAs (lincRNAs) is a prerequisite to analyze sequence features of non-coding RNAs and explore their regulatory function. Genomic sequence features provide fundamental backgrounds for lincRNA predictions, due to that sequence information at least partially aids such predictions. However, genomic sequence alone seems to reach an end involving sensitivity for...
In order to improve the prediction accuracy of yarn quality based on BP neural network, in this paper, differential evolution algorithm is applied to train BP neural network. By using six parameters of raw cotton as the input node, and single yarn strength value and evenness CV value which characterize yarn quality indicators as the output node, a prediction model of yarn quality is developed. In...
Steganalysis is detecting and decoding hidden data within a given media and is taken as a countermeasure to steganography. There has been quite some effort in audio steganalysis for additive embedding model. But, results are disappointing when they distinguish the cover-audio signal with multiplicative noise and the stego-audio signal. In this paper, multiplicative noise is changed to additive noise...
Publish-Subscribe Services have been widely employed in distributed Real-Time applications. However, the standard technologies and model which provide the foundation for Publish-Subscribe Services do not address issues such as fault tolerance and dependability of services. Aiming to supply this gap, this paper describes Quality of Service (QoS) policies and provides concrete strategies and methodologies...
Condition based maintenance and diagnosis technology plays an important role in power system reliability, as it is able to identify the faulty sections in power systems before the failure occurs. With the development of smart grid technology, a lot of research has been focused on the online monitoring technology, condition based maintenance and diagnosis technology. This paper surveyed the current...
With the development of the smart grid technology, power distribution network puts forward a higher request for transmission bandwidth and reliability. First, we analyze the characteristics and the business needs of the distribution network. Then we analyze the distribution network communication technologies, both wired and wireless. Based on our analysis, we should combine various communication technologies...
Transform is an important method of risk analysis in actuarial science. In this paper, a new transform method is proposed by the minimum cross-entropy principle which is used widely in information theory. The more moment information of loss variable can be considered in the bounds of the optimization model. The solution of the constructed model,which is a transform of original probability distribution,can...
Information management plays an increasingly important role in enterprises with the constant improvement of computer and communications technology. It is known that enterprises have diverse security requirements when implement information security, such as cost, effectiveness, environment, commitment to law and ethic and etc. In this paper, an information security risk management method is proposed...
The common maintenance scheduling problem in restructured power systems is addressed. When Independent System Operator(ISO) receives scheduling plans from multiple independent GENeration COmpanys (GENCOs), which seek to maximize their own medium-term profits, it tries to trade off the generation cost and the reliability of the system, thus reschedules the maintenance plans of the GENCOs. This paper...
