Because of poor performance of heuristic algorithms on virtual machine placement problem in cloud environments, a multi-objective constraint optimization model of virtual machine placement is presented, which taking energy consumption and resource wastage as the objective. We solve the model based on the proposed discrete firefly algorithm. It takes firefly's location as the placement result, brightness...
To the requirements that SOC equalization system for real-time data acquisition and accuracy of voltage, temperature and current of each single battery, using the special battery test chips- LTC6804-1 made in the company of Linear which have been cascaded and combining microprocessors of Freescale KEA128 series can complete the data collection to a large number of cells in a relatively short period...
The working status information of key equipments serving at operation and control system is of great value for safe and productive operation in urban rail transit. Properly utilizing and tracking the working status from operation record data, is for sure meaningful in evaluating the working status of those key equipments, and can thus acquire the stage status in their life cycles. In this paper, based...
Regret is a negative social affect arising from upward counterfactual thinking for adverse outcomes. The neurophysiologic markers of identifying regret based on feature extraction from EEG signal has yet to be investigated. The EEG signals were recorded while 25 subjects performed a gambling task involving feedback for the subjects' chosen selection, the alternative selection, or for both. After the...
Medical images are being utilized progressively inside the healthcare services for diagnosis, guiding treatment, planning treatment and checking illness progression. In fact, medical imaging chiefly processes uncertain, lost, vague, complementary, conflicting, redundant contradictory, distorted information and data has powerful structural character. As a general approach, the comprehension of any...
Real timely, intuitively monitoring the transportation status of material flow is a fundamental basis on belt conveyor speed control operation. To improve the detection precision and visualization degree, the article presents a method on 3D reconstruction of material transportation status on belt conveyor. A Laser Scanner LMS291-S05 is used to acquire a serials of 2D contour lines in real time, combined...
In the extraction of halftone anti-counterfeiting information, the image maybe skew, which causes the anti-counterfeiting information cannot be extracted. Using dots characters to construct the synchronous information, we propose a halftone dots detection algorithm based on cluster analysis. This algorithm detects dots with different in the halftone images, then extract the synchronous information...
Biomedical image processing is an emerging and most challenging field in recent years. Large sets of similar images are produced by medical imaging applications. Manual image interpretation and analysis becomes a fastidious task due to the huge amount of data. In medical image processing, to classify an image on the basis of statistical inference, MRF classification is a well established method. In...
Update summarization is a challenge in automatic text summarization. The task aims to distill evolved messages from a collection of new articles, under the assumption that the reader has already browsed the previous articles. In this paper, we reviewed some state-of-the-art approaches for extracting update summarization and then focused on a LSA-based one. After the analysis of LSA-based approach's...
The Christmas and new year 2016 are coming, in order to stimulate the future development, explore novel applications, and exchange ideas for developing robust solutions, the 12th International Computer Conference on Wavelet Active Media Technology and Information Processing 2015 (ICCWAMTIP 2015) is held at University of Electronic Science and Technology of China (UESTC) in Chengdu on December 2015...
Hainan primitive Li brocade images were analyzed to find the features of Images. The image elements were obtained through the treatment of Li brocade images using different multimedia image processing techniques and processing methods, including image segmentation, cutting, denoise, and extraction etc methods. The image elements were reconstructed to generate new Li brocade images, using transformation...
A non-intrusive computer vision based ideas has been utilized for the development of a Drowsy Driver Detection System. The small camera has been used by system that focuses straight towards the face of driver and checks the driver's eyes with a specific end goal to recognize fatigue. A warning sign is issued to caution the driver, in such situation when fatigue is recognized. This paper illustrates...
This paper presents a novelty classification method based on multivariate Bernoulli naive Bayes with Dirichlet prior and hyper parameter optimization. We test the proposed method on 15-Scenes and Msrc-v2 data set by comparing with basic multivariate Bernoulli naive Bayes and SVM (Support Vector Machine). The experiments show that our method has advantages both in running time and classification precision.
In this paper, we design a social-relations-based routing algorithm (SRBRA). Firstly, by analyzing the real-time data from mobile nodes in the network, we summarize and extract factors that affect social relations between these mobile nodes. Then make inference and evaluation for the complexity and dynamic of these factors from multiple angles, calculate the social-relations values between each sensor...
