Scanning attack threatens the security of network communication severely. Traditional network communication usually uses static IP address configuration, which provides convenience to scanning attackers. In this paper, an IP Hopping (IPH) communication scheme is proposed based on software-defined network to solve this problem, in which IP addresses can be assigned to the hosts in the network dynamically...
According to the human physiological sensor communication needs of transmitting information rapidly and gathering data to the information node conveniently, the mobile's feature of communication fast and use easily is used as the gathering node for forwarding data and applying data. The study on the implementation methods of wireless sensor data interface and the open-frame of the software are carried...
Software trustworthiness is an important area of software reliability. How to measure it is a challenging. This paper aims at developing a new measurement model of software trustworthiness. For this propose, we first define the trusted evidence as a program unit or element which causes the untrustworthy. Then, we classify them and propose a measurement model to measure the degree of software trustworthiness...
High-performance parallel storage systems, such as those used by supercomputers and data centers, can suffer from performance degradation when a large number of clients are contending for limited resources, like bandwidth. These contentions lower the efficiency of the system and cause unwanted speed variances. We present the Automatic Storage Contention Alleviation and Reduction system (ASCAR), a...
This paper studied the modeling and simulation of the public opinion propagation in the small-world network. The public opinion information propagation characteristics were firstly analyzed, and different states of the people in the propagation environment were proposed. Based on that, this paper constructed the public opinion propagation model based on the agent modeling method, and proposed the...
It is difficult to predict the hot-spot temperature-rise due to the uneven distribution of structure parts stray loss of large power transformer. This paper calculate the stray loss of transformer structure parts by using FEM, then treat it as heat source to obtain the accurate temperature distribution based on magnetic-thermal coupling method, and appropriate magnetic shields are used to reduce the...
MapReduce plays an critical role in finding insights in Big Data. The performance optimization of MapReduce programs is challenging because it requires a comprehensive understanding of the whole system including both hardware layers (processors, storages, networks and etc), and software stacks (operating systems, JVM, runtime, applications and etc). However, most of the existing performance tuning...
High frequency pulse injection is part of many diagnostics techniques, e.g. cable fault location. An injected pulse along an underground power cable will reflect at an impedance impurity, for instance a cable joint. These joints can be identified based on pulse reflections only if sufficiently high-frequency components can be detected. Signals with higher frequency components can provide more accurate...
Seafloor massive sulfides have the potential to become a significant mineral resource because of ample contents of Au, Ag, Cu, Zn, and Pb. In this paper, economic evaluation software for seafloor massive sulfide deposits is developed. A project of seafloor massive sulfides is selected as an appLication of the software. By sensitive analysis, some important factors to affect the economic feasibiLity...
This paper focuses on study the geographic information service theory under the framework of digital earth, combining with geographic theory to make explanations on application model of geographic information service system, system structure, the establishment and the deployment model, introduces various geographic information services, map service and its function in ArcGIS Server, and then make...
In view of the shortcomings of traditional multi-objective optimal methods, this paper introduces iSIGHT which is a kind of optimal design software. Based on optimal design framework Isight, the multi-objective optimal design method and step using the Neighborhood Cultivation Genetic Algorithm (NCGA) are investigated. Taking a multi-objective optimal design of spring as the example, the Pareto optimal...
According to the need of industrial and agricultural production and living, we introduce “scatter sequence” of a regular triangle and build an optimization design model to maximize the minimum scatter numbers. Based on LINGO software, we obtain the solution of the minimum scatter numbers and their coordinates in some “scatter sequences” of the regular triangles with different numbers of points and...
During the “white Plus black” reform on the old cement concrete pavement, the stress concentration occurs at theseams beneath the asphalt layer bottom under the loading.Adopting appropriate measures to relieve stress is the key tosuccessful reform. Using ABAQUS finite element software, the analysis is taken to reflect the changing rules on the stress and deflection of asphalt overlay bottom in various...
As the power transformer has been to the direction of high voltage and large capacity. Therefore, the calculation of major insulation and longitudinal insulation has been played a more and more important role in transformer design. Use the simplified equivalent circuit as the calculated model. The calculation software for wave process of power transformer winding is developed with Matlab language...
This paper introduces the framework and the design, it mainly analyses the design methods of hardware and software in the main circuit, the system has characteristics of highly auto-controlling, avoiding error, using conveniently, and good military and business benefits.
In order to solve the problem of impact in robotic force position control during the initial state, the hyperbolic tangent filter function which was constituted a non-linear PID was used to process tracking error and speed. A robot force and position controller without impact was achieved. The Popov method was applied to prove the stability of the system. Based on the force and position control experiment...
At present the service science and engineering research are mainly focus on service discovery, service composition, service reputation and other key technical of the service computing. However the basic theory of service science, in particular, the basic principle of service and the evolution mechanism of service network only have some preliminary of research and exploration. The atomic services as...
During the realizing process of remote attestation, except for using trusted computing technology to protect physical security, storage security and operation security of certifier, cipher mechanism need to be combined to ensure the credibility of attestation method of certifier. This paper designs an attestation method model of property remote attestation, and applies the authentication and access...
The flow of information security is commonly controlled by different trust domains in the distributed environment. The information sharing in a unique trust domain, however, is also an essential issue to be further studied. Fortunately, the trusted computing technology provides a nice solution to elaborate the security of information sharing in the same trust domain. In this paper, trusted terminal...
