With the increase of students, electronic laboratories and instruments have become in critical need in many universities and colleges, thus the construction of virtual laboratory and virtual instruments have attracted attentions of many researchers. LabVIEW is the most widely used virtual instruments developing software with the most powerful functions, which can be used for virtual instruments developing,...
In order to study the solvability on a new system of nonlinear variational inclusions in Hilbert Spaces, the operators involving three classes of (K,η) are proposed in the paper, and a new algorithm for solutions of this system is constructed. The approximation solvability for the system of generalized nonlinear variational inclusions is discussed by using the resolvent operator technique in a Hilbert...
This paper takes pedestrian walking speeds as the research object at the signalized intersection crosswalks. Through on-site investigations and screening four signalized intersections are chosen as the data collection points. Combining the field observations with video footage methods the original data is gotten. Pedestrian speeds are counted. Walking speeds of pedestrians are studied in relation...
In this work, we study the parity complexity measures pCmin[f] and PDT[f]. Pcmin[f] is the parity kill number of f, the fewest number of parities on the input variables one has to fix in order to "kill" f, i.e. To make it constant. PDT[f] is the depth of the shortest emph{parity decision tree} which computes f. These complexity measures have in recent years become increasingly important...
The audio track of music melody includes a lot of useful information of music melody, which is the basic of music character recognition and also the premise work in the design of the performance plan of music foundation. Five eigenvectors : pitch, length, tone tempo and strength are extracted for the expression of music melody, by which, the basic music character recognition system can be set up....
Though many Information Assurance (IA) educators agree that hands-on exercises and case studies improve student learning, hands-on exercises and case studies are not widely adopted due to the time needed to develop them and integrate them into curriculum. Under the support of National Science Foundation (NSF) Scholarship for Service program, we implemented two faculty development workshops to disseminate...
As smart mobile devices become increasingly popular, so do the incentives for attackers. Mobile devices' prevalence and mobile threats' rapid growth have resulted in a shortage of mobile-security personnel. We need educational activities to promote mobile-security education and meet the emerging industry and education needs. However, mobile security is a relatively weak area in most schools' computing...
In this paper, we consider group consensus problem with switching topology by giving a kind of new protocol in which communication graph weights are all nonnegative. This is also consistent with classic protocols. The sufficient conditions which group consensus under this kind of protocols can reach for both single and second order multi-agent system are obtained. Finally, numerical examples are given...
Infrared and visible image fusion, as a powerful tool for the object detection and recognition, has developed with the advent of various imaging modalities. However, resulting images of traditional methods are always difficult to compromise between multimodalities. This paper has solved this problem by a variable-weight fusion rule based on the non-sub sampled contourlet transform (NSCT). The original...
The existing service selection methods consideration trust, basically consider the trust of QoS. In fact, the trust of service selection is not only about that of QoS, but the trust of the output data of Web service. However, the trust of the output data is related with the input data of Web service and the treating process of output data, that is to say, the trust of output data is related to the...
To overcome shortcomings in existing embedded system education, this paper presents an ongoing work on developing a novel Android-based Mobile Sensory System Lab ware that is portable, affordable, and easily adoptable. The proposed lab ware can facilitate authentic and creative learning of embedded systems and provide extensive hands-on experience using mobile embedded platforms. Preliminary feedback...
Through using the ArcGIS software as the platform, and taking DEM analysis, raster calculation and spatial interpolation of spatial analysis technology as the core method, this paper selects Menghai County as the study area, combines with the Delphi method, analytic hierarchy process, fuzzy membership function, farmland Integrated Fertility Index ( IFI ) and other methods, to establish major factors...
To address the need for innovative mobile security learning materials and for promoting mobile security education, this paper presents our work-in-progress effort on developing a real-world relevant security labware to provide students with mobile threat analysis and protection experience. A preliminary evaluation has been conducted on the pilot labs and positive feedback has been received.
In distributed environment, in order to manage and share data resources better, tracking the origin and evolution of the data is needed to obtain the data provenance information, used to judge the quality and credibility of the data. In order to provide the framework basis which is used to analyze the dependent relationships of data provenance, a tracking framework for distributed environment based...
By analyzing the problem and key technology about integration of heterogeneous database, a distributed database integration model with global schema based on multi-agent technology is proposed. Firstly, distributed database (DDB) global schema and fragment and assignment schema are designed according to actual instance of production organization. Secondly, multi-agent system of administration architecture...
The character recognition in landmarks is one of the key technologies in automatic navigation. After introducing the landmark recognition system, the character recognition algorithm based on the multiple perceptron neural network is presented. First of all, the algorithm is simulated in MATLAB, and the weights and thresholds for the sampled landmark character are obtained by training the perceptron...
A formation control approach for multiple robots in uncertain environments is proposed, which adopts the formation parameter matrix to establish the relative relationship among robots, decomposes the global-level formation control problem into the-off-axis point of the follower tracking the-off-axis point on the virtual robot which has the same orientation with the lead robot and maintains a desired...

Thirdly,...
Many automatic systems of electric power system, such as, Energy Management System (EMS), Tariff Meter System (TMS), etc, usually have separate data model that it's necessary to achieve resource sharing and data integration of these automatic systems. This paper introduces the research and development of distributed data integration query system based on CORBA which integrates the real-time data that...
Video monitoring systems have been widely used by some enterprises to improve industrial safety; however, they are not perfect tools for the job under the prevailing system configuration: there are few displays for a large number of video cameras and monitoring personnel may fail to detect all potential safety hazards as a result of their susceptibility to eye strain. In order to solve the problem,...
