“…The resultant agricultural nonpoint source pollutants were flushed into the rivers along with drainage and precipitation through field ditches, and finally rushed to Poyang Lake and affected the lake water quality. As a primary sewage interception channel in agricultural nonpoint source pollution control pathway, the ecological ditches have been investigated by many researchers [3][4][5][6][7][8] on their ability to intercept the nutrients. The research findings showed that the ditch sediments have a stronger nutrient-removing ability.…”

A broad attention has been paid to the field ditches as the sewage interception channel for the agricultural nonpoint source pollution, however, rare studies have involved in the phosphorus migration and transformation between the ditch sediments and overlaying water, especially, from the ditch sediments to the water. The present paper aims to explore with XPS binding energy data how pH, dissolved oxygen, sunlight affect the process of phosphorus migration and transformation in ditch sediments to the water by methods of changing pH, aerating nitrogen and oxygen in water and changing the sunlight; and hopes to provide a guidance on how to give full play to the ditch's sewage interception capacity and avoid ditch becoming pollution source reversely. The experimental results with XPS binding energy data show that no electron transfer occurs insignificantly at different pH values in sediments, i.e. no electron transfer reaction occurs on surface. This reveals that the phosphorus absorption form HPO 4 2in sediment substitutes OHstate on the sediment surface. The amount of phosphorus migration and transformation is the minimum under the neutral condition, and the maximum under the alkaline condition. Under aerobic atmosphere, the data of XPS binding energy shows the surface charge of iron after oxygen aeration reduces, the surface charge of oxygen increases, i.e. Fe 2+ is oxidized into Fe 3+ , the phosphorus is absorbed increasingly; the experimental results with XPS binding energy data disclose there exists electron transfer reaction significantly, that is the illumination affects the process of phosphorus migration and transformation through dissolved oxygen (DO) and the pH impacted on the biological processes under the presence of sunlight in sediments, indirectly. The influence of illumination on the sediment phosphorus migration and transformation is regular insignificantly. Conclusively, the amount of migration and transformation in sunlight-free group is greater than the sunlight group.

“…In recent years, more and more scholars have begun to focus on and study the agile manufacturing system oriented job shop scheduling and dynamic scheduling [4][5][6][7][8]. Chao-Yong Zhang et al investigated the dynamic scheduling in the cases of delayed arrival, processing of raw materials and assembling, as well as adding the new jobs urgently [9].…”

Rapid development of the Internet of Things not only provides large amounts of data to the job-shop scheduling, but also proposes a great challenge for dynamic job shop scheduling. A dynamic job shop scheduling approach is proposed based on the data-driven genetic algorithm. Application examples suggest that this approach is correct, feasible and available. This approach can provide the technical support for the long-term development of enterprises in the field of intelligent production.

“…The algorithm is not restricted to the problem that the inverse matrix of the transformation matrix does not exist; (c) The algorithm is based on the GPU. DirectX 11 Shader (compute shader) was used to make point conversion and distance comparison operations thanks to the powerful GPU's parallel computing capabilities [9,10]. Compared with the algorithm running on the CPU, Pick up speed is 2-3 times faster.…”

Three-dimensional fine point cloud has gradually become a key data source of three-dimensional model. The large scale point cloud interactive quick pick up is a kind of important operation in the point cloud data processing and applications. Since the point cloud model is composed of massive points, the speed of ordinary picking method is limited. A GPU-based point cloud picking algorithm was thus presented to solve the problem. The basic idea of the algorithm is that by spatial transformation converting the point cloud to screen space, and then, the point was calculated which is the nearest to the mouse click point in screen space. The GPU's parallel computing capabilities were used to achieve spatial transformation and distance comparison by compute shader in this algorithm. So the speed of the pickup has been increased. The results show that compared with the CPU, the pickup method based on GPU has greater speed advantage. Especially for the point cloud over 4 million points, the speed of the pickup has been increased 2-3 times faster.
