1How do machine learning techniques help in increasing accuracy of landslide susceptibility maps?显示文摘Landslides are abundant in mountainous regions.They are responsible for substantial damages and losses in those areas.The A1 Highway,which is an important road in Algeria,was sometimes constructed in mountainous and/or semi-mountainous areas.Previous studies of landslide susceptibility mapping conducted near this road using statistical and expert methods have yielded ordinary results.In this research,we are interested in how do machine learning techniques help in increasing accuracy of landslide susceptibility maps in the vicinity of the A1 Highway corridor.To do this,an important section at Ain Bouziane(NE,Algeria) is chosen as a case study to evaluate the landslide susceptibility using three different machine learning methods,namely,random forest(RF),support vector machine(SVM),and boosted regression tree(BRT).First,an inventory map and nine input factors were prepared for landslide susceptibility mapping(LSM) analyses.The three models were constructed to find the most susceptible areas to this phenomenon.The results were assessed by calculating the receiver operating characteristic(ROC) curve,the standard error(Std.error),and the confidence interval(CI) at 95%.The RF model reached the highest predictive accuracy(AUC=97.2%) comparatively to the other models.The outcomes of this research proved that the obtained machine learning models had the ability to predict future landslide locations in this important road section.In addition,their application gives an improvement of the accuracy of LSMs near the road corridor.The machine learning models may become an important prediction tool that will identify landslide alleviation actions.Yacine Achour Hamid Reza Pourghasemi 2020Geoscience Frontiers2020,11,3:11

3Structural, optical and electrical properties of zinc oxide thin films deposited by a spray pyrolysis technique显示文摘Zinc oxide(ZnO) thin films were deposited on glass substrates by spray pyrolysis technique decomposition of zinc acetate dihydrate in an ethanol solution with 30 m L of deposition rate, the ZnO thin films were deposited at two different temperatures: 300 and 350°C. The substrates were heated using the solar cells method.The substrate was R217102 glass, whose size was 30 17.5 1 mm3. The films exhibit a hexagonal wurtzite structure with a strong(002) preferred orientation. The higher value of crystallite size is attained for sprayed films at 350°C, which is probably due to an improvement of the crystallinity of the films at this point. The average transmittance of obtain films is about 90%–95%, as measured by a UV–vis analyzer. The band gap energy varies from 3.265 to 3.294 e V for the deposited Zn O thin film at 300 and 350°C, respectively. The electrical resistivity measured of our films are in the order 0.36 cm.Yacine Aoun Boubaker Benhaoua Brahim Gasmi Said Benramache 2015Journal of Semiconductors2015,36,1:2
