ECG is an important tool to assist in heart diseasesdiagnosis. The works found in the literature have the common goal of discriminating between binary study groups, one pathological and one control, even when ECG records from patients diagnosed with several pathologies are available in the databases. This work proposes a method to detect ECG morphological features and to analyze the capacity of this ECG features to discriminate 28 pairs of study groups, combining 7 pathological groups and 1 control group, presented in the PTB Diagnostic ECG Database. For each pair, it was achieved an accuracy between 77.4% and 100%, with an average of 94%, using several pattern recognition classifiers.

Presently a day's online shopping has accomplished an enormous disrepute privileged less measure of time. As of late few ecommerce sites has been created their functionalities to a point with the end goal that they suggest the product for their clients alluding to the availability of the clients to the social media and give coordinate login from such social media, (for example, facebook, Google+ ,and so forth). For suggesting the clients that are absolutely new to the sites, we utilize novel answer for cross-webpage cold-start product recommendation that goes for prescribing products from online business sites. In particular, we propose learning the two clients and products include portrayals from information gathered from internet business sites utilizing repetitive Matrix Factorization to change client's social networking highlights into client embedding's. We at that point build up a feature-based matrix factorization approach which can control the learnt client embedding for cold-start product recommendation.

The dynamics of salt lands is one of the major problems facing agriculture in Senegal, despite the many efforts made to promote this sector of activity. Detecting changes in land use from a precise mapping of land use units makes it possible to assess and monitor the evolution of salt lands. The analysis of changes in morphological units that occurred during the period studied is based on a diachronic mapping of land use and use patterns and their distribution. Our study deals with the detection of land use changes in Foundiougne Department. A pixel-based classification approach and the maximum likelihood algorithm were chosen. The data used relate respectively to the Landsat TM images of 1986, ETM + of 2000 and OLI of 2015. The changes were detected by the method of post-classification comparison of the results of the three classified images. The overall details of the classifications give satisfactory results with..........

The extraction of curvilinear features of road networks in digital images from Remote Sensing (RS) is very important for Cartography, because this extraction contributes to updating cartographic products. As different curvilinear features of a road network present in the same image usually have distinct characteristics, a single method or technique can extract features precisely in one area of the image, but only partially in another area of the same image. Consequently, features extraction methods usually present results with failures, compromising the quality of the extraction of the curvilinear features of the road network in the image as a whole. Aiming at presenting an alternative to improve the results from the extraction of road network in digital images, this paper proposes a semiautomatic method for post-processing digital images from remote sensing in order to reconstruct curvilinear features..........

Many studies have shown that nanoparticles such as zinc oxide (ZnO), possesses potent antimicrobial activity. This study aimed to evaluate the antifungal activity of ZnO, tungsten oxide (WOx) nanoparticles, and the ZnO/WOxnanohybrids against pathogenic basidiomycete fungi, R. mucilaginosa. Coupling of ZnO and WOx nanoparticles was performed using liquid impregnation method. EDX analysis confirmed the presence of ZnOnanoparticles on the surface of WOxnanoparticles. Antifungal susceptibility assays showed that ZnO nanoparticles possessed better antifungal activity as compared to WOx and ZnO/WOxnanohybrids (p<0.001, n=3). Time kill assay also showed significant killing kinetics in ZnO NPs as compared to WOx and ZnO/WOxnanohybrids..........

A banana-shaped vibrating screen (also called banana screen) is a device for the separation of bulk materials into granules according to different sizes. It is a combination of multi-decks having different inclined angles, which is widely used in screening plants [1-3]. The screening efficiency is one of the most important criteria to evaluate the machine performance, and it depends on various factors, such as the deck inclination angle (screening surface angle), vibration frequency, vibration amplitude, material properties, etc [4-9]. The banana-shaped vibrating screen is a specially designed vibrating screen, in which the screening efficiency greatly relies on the inclination angle of decks...........
