Since the present algorithms are on the assumption of correct beacon information, when the network is attacked, especially the beacons are captured by opponents, all algorithms will not work. To address this issue, one attack-resistant nodes localization algorithm we call VDV-Hop(Voting DV-Hop) which is on the basis of DV-Hop algorithm and based on the voting mechanism is presented. This algorithm...
The standard FCM is sensitive to noise deficiencies. To solve this problem, this paper presents an adaptive FCM algorithm. By way of combining cluster validity function into FCM algorithm, the adaptive identification of the cluster Numberc can be realized The experimental results show that, the improved algorithm is a robust and efficient remote sensing image ossification method
Firing dispersion is an important technology index, which can estimate artillery machine performance, the research on firing dispersion and probability of projectile shooting object have important meaning. The errors of artillery shooting and firing accuracy were used to analyze firing dispersion influence characteristic. According to the theory of projectile proximity and mathematical statistics...
In this paper, we propose an effective non-iterative filter-based refinement approach called in-situ color-weighted median filter(ICWMF) as to improve the accuracy of disparity map. The ICWMF only needs the disparity map and corresponding color frame as input. Expressed as a weighted median filter, our method generates the refining output by considering the information of the color image to calculate...
We propose a multi-segment approximation method to design a CMOS current-mode hyperbolic tangent sigmoid function with high accuracy and wide input dynamic range. The dynamic range is dependent on the number of segments and the accuracy is related to the dividing point. From mathematical results, we can observe the proposed method outperforms traditional methods. We implement the multi-segment approximation...
The emerging background for automatic extracting collocations is generally stated in this article. That How to extracting collocations as well as the advantage and disadvantage of existing methods are particularized. The review and comment for domestic and international present research status are given. And the problem of existing technic and solving methods are discussed.
Currently, since the robustness and anti-interfernce performance of mining method of vehicle failure are weak, the accuracy of failure mining is low. To solve the problem, this paper put forward a new mining technology of vehicle failure based on resisting the interference from the exterior. Through accurately building vehicle model, establishing search model of vehicle characteristic point, dealing...
We present an easy-to-use web server that makes it possible to use a number of known yeast transcription factor binding sites and a novel algorithm for predicting transcription factor binding sites. The 8 kinds of novel evaluating indicators are clearly above the known other 10 algorithms at binding segment level and nucleotide level respectively. The correlation coefficients reach 0.45 and 0.56,...
In view of the object in the image pixels and edge pixel to pixel adhesion, adhesion components due to the occurrence of the pixel gray mixed pixels, resulting in minimal differences, the traditional edge detection algorithm based on gray level because they can't distinguish adhesion part gray difference, cannot complete image edge detection problem. The image edge segmentation algorithm based on...
