SonarQube will increase the reliability of the Spectral Workbench, which provides numerous benefits including increased confidence in its data and effectiveness which will drive additional number of users for spectral repository data collection.
Disaster management strategy for avoiding the future losses by a slope failure at Nanhuan road, Fuxin area, Northeast China
Many surrounding areas in the vicinity of failed slope at Nanhuan road, Fuxin area, Northeast China are witnessed as the signs of disaster. The observed settlement as wastage of an active mass in the area has been observed after the excessive precipitation in 2012 (May to October) which caused infrastructural damages (Roads at the top and bottom of the failure zone), agricultural fields and residential areas. Therefore, the paper proposes examining this subject. An extensive field investigation was conducted in the area of Fuxin, west of Liaoning province China. It is recommended and suggested that a series of disaster prevention and both structural and non-structural mitigation measures with the involvement of government and local community are required, to be prepared in advance for avoiding the future economic loss as well as the impending disaster in the area. This paper also highlights the need of investigation in response mechanism and forward planning for awareness initiatives: to avoid the future hazard in the remotest failure zones of Fuxin area, Northeast China.
This paper studies the migration of fish caused by the rise of sea water temperature caused by global warming. It is required to predict the migration sites of herring and mackerel in the next 50 years, as well as the best, worst and most likely time for small-scale fishing companies in the original area of Scotland to continue fishing, and to formulate reasonable business strategies for such companies, while taking into account the territorial waters of other countries. The grey prediction model and linear regression model are established. By querying the sea temperature in the geographic location range ( , ) from 2010 to 2018, we predict it in terms of the quarter as the time unit. Because the result of grey prediction model is not in accordance with the reality, the final data is obtained by linear regression model. According to the data analysis, the migration routes of fish are all northward, and the main direction is to migrate to the coast of Norway, but some of herring will move to the coast of Iceland later. The grey prediction algorithm and BP neural network algorithm used in this paper have been widely used in solving all kinds of practical problems in reality, so the conclusion of this paper is feasible and extensive.
To solve the problem of EMU maintenance planning time, we established a hybrid linear programming model based on adaptive genetic algorithm. According to the different levels of bullet train maintenance and the different arrival time, the constraint conditions are found, and the overall minimum maintenance time is taken as the objective function. Then the problem is transformed into a hybrid Flow-shop scheduling problem with unique process constraints, and an adaptive genetic algorithm is used to solve it again. It is concluded that the total maintenance takes 1125 minutes, and no blockage occurred in all EMU during the maintenance period. To provide a consistent basis for bullet train maintenance time and scheduling.
Integrated Application of Organic and Inorganic Fertilizer to Improve Nutritive Quality of Maize and Soybean Intercrop
A field experiment was conducted to evaluate the use of integrated fertilizers on the nutritive quality of maize and soybean in intercropping system in 2014 at field 2, Universiti Putra Malaysia (UPM) Serdang, Selangor, Malaysia. Fertilizer applications were either in the form of inorganic (NPK) or poultry manure (PM). Treatments comprised of combinations of three intercropping systems (sole maize, sole soybean, and maize + soybean) and four nutrient managements (control, 100% NPK, 100% PM and 50 % NPK + 50% PM). The experiment was laid out in a randomized complete block design (RCBD) with 3 replications. Results showed that intercropping maize with soybean significantly reduced protein and nutrient content of soybean; however, the oil content of soybean, sugar, oil, protein and nutrient content of maize were not significantly affected by intercropping. Sole and integrated application of NPK and PM increased the quality of both crops over control. Integrated application of 50% NPK and 50% PM fertilizer gave higher oil, protein and nutrient content of both crops. Use of 100 % PM gave better quality than the application of NPK fertilizer for both crops.

Charging pile inquiry and reservation, fee settlement, user community communication and other functions make the electric vehicle charging service platform more intelligent and convenient. At the same time, as a bridge between electric vehicles and charging stations, “Gathering” can combine the real-time electricity price, the degree of traffic congestion, the use of charging piles and the load of the power grid to plan more efficient and convenient charging suggestions for users. Make full use of power resources to reduce the load and cost of the grid.
The effects of particulate matter (represented by humic acid, kaolin and algae) on ultrafiltration membranes in micro-polluted water sources were investigated, and the mechanism of ultrafiltration membranes was further understood with the change of membrane flux and transmembrane pressure difference. The results showed that the removal rate of kaolin and algae by UF membrane was over 99%, while the removal rate of humic acid was only about 72%. Moreover, the extent of UF membrane fouling caused by humic acid was larger than that caused by kaolin and algae. The higher the concentration of humic acid, the more serious the membrane fouling was. Ultrafiltration membranes contaminated by humic acid were washed by 0.05mol/L NaOH alkali and 0.05mol/L HCL acid. The permeability of the membranes was restored to 91.24% of the cleaned surface, which was better than that of pure water, sodium hypochlorite and sodium hydroxide. It can provide better guidance for choosing appropriate cleaning agents for ultrafiltration membrane fouling.
