We make the cross-match with the two functions, and then we obtain the union set of the two different sets. We use the ThreadPool technique to speed up the cross-match. In this way improved accuracy can be obtained on the cross-match. Our experiments show that this algorithm has a remarkable performance superiority compared with the previous ones and can be applied to the cross-match between large-scale catalogs. We give some ideas about solving the many-for-one situation occurred in the cross-match.展开更多

There is a broad research area, covering mathematical, statistical, information theory methodologies for anomaly detection. It addresses various problems in a lot of domains such as health, education, finance, government, etc. In this paper, we analyze the state-of-the-art of data streams anomaly detection techniques and algorithms for anomaly detection in data streams (time series data). Critically surveying the techniques’ performances under the challenge of real-time anomaly detection of massive high-velocity streams, we conclude that the modeling of the normal behavior of the stream is a suitable approach. We evaluate Holt-Winters (HW), Taylor’s Double Holt-Winters (TDHW), Hierarchical temporal memory (HTM), Moving Average (MA), Autoregressive integrated moving average (ARIMA) forecasting models, etc. Holt-Winters (HW) and Taylor’s Double Holt-Winters (TDHW) forecasting models are used to predict the normal behavior of the periodic streams, and to detect anomalies when the deviations of observed and predicted values exceeded some predefined measures. In this work, we propose an enhancement of this approach and give a short description about the algorithms and then they are categorized by type of pre-diction as: predictive and non-predictive algorithms. We implement the Genetic Algorithm (GA) to periodically optimize HW and TDHW smoothing parameters in addition to the two sliding windows parameters that improve Hyndman’s MASE measure of deviation, and value of the threshold parameter that defines no anomaly confidence interval [1]. We also propose a new optimization function based on the input training datasets with the annotated anomaly intervals, in order to detect the right anomalies and minimize the number of false ones. The proposed method is evaluated on the known anomaly detection benchmarks NUMENTA and Yahoo datasets with a展开更多

Brought in conjunction with the capacity for manufacturing at low temperature, likewise from the solution, devices based on perovskite, particularly solar cells have been contemplated seriously with striking advancements in performance, in the course of recent years. The amalgamation of minimal effort, high efficiency and extra applications gives incredible potential to commercialization of these cells. The applications and performance of perovskite cells frequently relate with the structures of the device. Numerous creative structures of the devices were produced, targeting for vast scale manufacture, diminishing creation cost, upgrading the PCE and subsequently expanding the prospective for future applications.

For most of the women living there, the experience of this period does not seem to be very problematic. For women living in rural areas, other concerns are more prominent. Methods: The study was prospective, quantitative and qualitative about 500 cases collected over a period of 6 months. The study involved postmenopausal women in the Niamey region of public services, in certain residential areas, or accompanying people in health structures. Parameters taken into account were sociocultural, antecedents, experience, knowledge, and management of menopause. The data was entered and analyzed using Microsoft Office Word 2010 and Microsoft Office Excel 2010 software. Results: The average age was 56.4 years with extremes of 40 and 80 years;57% were still living with their husbands and 39% widows;60.2% housewives;53% uneducated, 17% have higher education;60.2% had had at least 6 children and 39.6% had used contraception. The comorbidities observed were arterial hypertension (24.4%) and diabetes (7%). As for the representation that women made of menopause, for all of them, this stage is the beginning of old age. The most frequent signs were asthenia (86.2%) and mood disorders (70.6%). Almost all of the patients (99.8%) had not used hormonal treatment for the menopause and among them 27% the management of the menopause was with traditional means. Conclusion: Menopausal disorders are certainly a reality in our socio-cultural context. They are not a primary concern either through ignorance or resignation of the women concerned.展开更多

Especially for the violent mixing in HTM, refractory can also be impacted by molten metal (iron or steel), so it is very important to study and find out new refractory to meet the demand of HTM. Suitable refractory not only can stand the eroding of slag and liquid metal, but also can reduce the loss of electromagnetic energy. According to the experimental results, the influence of different refractory on electromagnetic force is unconspicuous, the refractory with Al2O3-base is better than that with MgO-base for standing the erosion by slag and iron. Al2O3-base refractory is more suitable for HTM process.展开更多
