Online E-commence has been growing rapidly in the world. Online bidding has become popular. This work will come out with a model of online bidding system (OBS). This paper propose a new model to deal with online bidding, we deal with auction with Cournot Bidding Data Mining (CBDM). CBDM framework based on Cournot model is designed for K-means clustering. The input auction space is partitioned into...
In robot-assisted needle-based medical procedures, path planning for a flexible needle is challenging with regard to time consumption and searching robustness for the solution due to the nonholonomic motion of the needle tip and the presence of anatomic obstacles and sensitive organs in the intended needle path. We propose a novel and fast path planning algorithm for a robot-assisted active flexible...
This article mainly analyzed the relationship between the WS small-world networks and information dissemination from small world network theory. It discussed the diffusion mechanism of negative information combined with the inherent characteristics of the negative information. And it established negative information transmission model based on the WS small-world network model. Finally, the model was...
In this paper, a new method to manage graduation photography is introduced. First, AdaBoost algorithm, which can achieve high detection accuracy, is adopted to detect faces in the graduation photography. After adjusting the position and adding the missed faces, the personal information of each photography is added into database. To get the current status of graduates, one can send emails to the member...
The quality of telecommunications services plays an important role in deciding whether to buy its telecommunications services for a consumer. This paper first analyzed the quality of telecommunications service and service quality gap. Then, we used the questionnaire method and analyzed the quality gap of TD services existedamong consumers. We find the self-mapping effect for consumers isthe main cause...
Virtual 3D hand is a natural and efficient tool of human-computer interaction (HCI), which is widely used in virtual reality (VR). In order to meet the needs of 3D Hand-based HCI, a novel platform is presented in this paper. Firstly, using cascade local coordinate systems and two direction vectors of hand, a new 3D hand model with a better design of thumb is developed. The presentation of articulated...
Because Scientific Research level has been an important indicator of college power, it's necessary to set up an Scientific research management system and make daily Scientific Management more normatively and effectively. In the process of exploiting and using Scientific research management system, security has always been given the first priority since it is pivotal for the survival of the system...
