Authors: Zhou Hao , Gao Yun , Yuan Guo Wu , Zhang Xue Jie
Published: May 2013

It is a key step to extract moving objects from background for computer vision applications. GMM based methods are the most commonly used technique for background subtraction in video sequence. However, how to establish efficient and precision background model with fast convergence rate is a Research-Worthy problem. In this paper, an effective scheme is proposed to accelerate the convergence rate of Adaptive-K Gaussian Mixture Model (AKGMM). The AKGMM algorithm alters the dimension of the parameter space at each pixel based on the changing frequency of pixel value. The number of GMM reflects the complexity of pattern at the pixel. An improved learning method is proposed for Gaussian Mixture Model. An adaptive learning rate is calculated for each Gaussian at every frame for speeding up the convergence without compromising model stability. Experimental results demonstrated that the proposed method gets a faster convergence while maintaining good robustness against complex environment compared to a conventional method.

Authors: Li Wei , Zheng Hong Yu , Zong Chang Fu
Published: May 2013

A brake pad wear control algorithm used under uncritical braking conditions is proposed to reduce the difference in brake pad wear between the front and rear axles caused by the difference in braking force and the type of brake. The algorithm regulates the distribution of braking force within the limits of certain braking regulations according to the wear conditions of the brake pads while deceleration control still functions properly. Computer co-simulations of braking with Trucksim and Matlab/Simulink was performed in which vehicle models with equal brake pad wear, greater wear on the front axle and greater wear on the rear axle were used. The results show that the difference in brake pad wear between the front and rear axles can be reduced by distributing the braking force according to the wear conditions of the brakes when braking uncritically to reduce the time and cost needed in repair and maintenance.

In order to provide a preliminary test and verification tools for curve saw processing technology, a research on complicated curve saw movement and cutting simulation based on virtual environment was conducted. Firstly, constructed the mathematical model of all movement axis, solved the motion law of between dicing saw and work piece by matrix arithmetic. To obtain a better graphics effect in cutting process, a dynamic mesh model based on self adaptive quad-tree was put forward. Finally the simulation system was achieved in the platform Microsoft Visual Studio 2010 and OpenGL which has a good effect and can meet the validation requirements of curve saw.
The Application and Research of the Distributed Electronic Authentication Based Software

Published: May 2013

With the development of the internet technology, office automation (OA) has brought people great convenience and at the same time OA as an very important approach to informatization, is required to better solve deeper problems to meet more objectives. Traditional identity authentication is through users name/password pattern, however, this mode is easy to access and the password is easily stolen and hard to remember. Especially on the public computers on public use, password-mode may bring very serious potential safety hazard to the users by being seen by others, being stolen by Trojan Program and so on. This thesis introduces how to use computer software to take the place of Password. This electronic authentication technology has three-leveled dispersed hierarchical organization which can identify the user in a very secured and absolute safe way.

Semantic modeling has become indispensable to integrate various specific security issues of Internet of Things. How to describe attack scenarios and how to define an intrusion unambiguously has been an urgent problem. For solving two above problems, a new three-level information security ontology model is proposed, which is an initial attempt to solve security issues by means of ontology technology. Five top classes are proposed in the domain ontology level. Then their subclasses are also proposed on the basis of actual scenarios in the local ontology level. Our intelligent laboratory, as experiment scenarios, is partly instantiated.

With the increased popularity and deployment of WLANs, a major challenge is how to efficiently assign these available channels in order to optimize the network performance. In this paper, we design a testbed to analyze the effect of Channel Interference and RSSI in IEEE 802.11b PCF. We have observed that the performance of all hosts is subject to important signal fading and interference. We believe that the data collected by our experiments may be of interest to network designers who want to know the effective capabilities before their deployment.

In this paper, it use Solid edge ST5 to establish the 3D model of manipulators designing for verifing the correctness of structure designing, and use ADAMS to simulate the sports of virtual prototyping for verifying the parameter of joints. Comparing the simulation results with theory of design structure, the scheme can fulfill the anticipative design requirements and successfully verify the feasibility of the design. In the design, it use Solid edge ST5 to establish the 3D model of manipulators designing, and use ADAMS to simulate the sports of virtual prototyping. Thus, we can reduce the design faults, shorten the test time, reduce the development costs to save the cost and improve the manipulator quality.
Chance Information Analysis of a Residential Building Development Case

Published: May 2013

In todays information age, information is wealth, especially the rare but significant chance information for human decision making. And the significant chance information is usually gained by analyzing the scenario graph which is generated by processing the data with a data mining algorithm. So the data mining algorithm is critical to create scenario graph and to obtain valuable information from mass of data. IdeaGraph is a data mining algorithm that not only works on discovering rare and significant chances, but also focuses on uncovering latent relationship among them, it can generate a rich scenario graph for humans comprehension, interpretation and innovation. In this paper, an experiment about residential building development case is performed to evaluate the effect of IdeaGraph in this field.

Multi-core processor technology is getting more and more common for both business and private use. However, the operating systems and applications are not keeping the same pace with multi-core hardware. In the mean while, to get better performance, more factors need to be considered under multi-core platform, e.g. load balance, cache, task relationship, etc. This paper focuses on making full use of multi-core processor through scheduling the tasks to proper core with CPU priority Algorithm which calculates a priority of each core when scheduling a task. With CPU Priority, it is easier to take interesting factors into account and combine several factors together. We did our work based on a scheduler simulator implemented with Python and we observed that, with CPU priority scheduling algorithm, it does suggest a flexible way to schedule the CPU assignment and is able to gain some satisfactory improvement on the response performance according to our simulation.

Published: May 2013

Knowledge integration played a major and centre role in the process of organizations knowledge innovation. Study on the knowledge integration contents and process in organization has important significance. There are four contents of knowledge integration in organization knowledge innovation: knowledge integration between different knowledge main bodies; different knowledge levels; the new and original knowledge system; personal study, team study and organization study. The paper discussed the process of knowledge integration toward organization knowledge innovation based on lify-cycle theory and divided the process into four stages: embryonic stage, development stage, mature stage and diffusion stage. The paper analyzed the knowledge value in different life cycle stages and the result indicates that the knowledge in mature stage is the most valuable.
