TL;DR: In this article, an optimal path planning simulation system in logistics distribution is presented. But the simulation system is not suitable for the real world, as it is limited to a single distribution path.
Abstract: The invention relates to an optimal path planning simulation system in logistics distribution. The system comprises a system main interface module, a shortest time planning module and a shortest path planning module, wherein the system main interface module integrates various operations of the shortest time and the shortest path; the shortest path planning module comprises the shortest path processing algorithms including a backtracking method and an improved simulated annealing algorithm; and the shortest time planning module sets the speed of each road section into a different value according to actual needs, and calculates the shortest time of a logistics truck passing all customers. A user of the system can mark the addresses of warehouse and customers on the simulation system interface according to actual conditions; the simulation system can plan a policy according to the path selected by the user; and the simulation system can perform dynamic adjustment if traffic jam happens on a road section and re-plans the distribution path, thereby reducing the cost of the logistics truck in the distribution process.

TL;DR: In this article, a decision support system for risk assessment of heavy metal pollution in farmland soil is established, in which technologies such as web-based geographic information system, quick response code, radio frequency identification, and web service are introduced as the bases.
Abstract: Heavy metal pollution in farmlands is a serious threat to sustainable agricultural development and has become a major agro-ecological problem that has attracted public concern in China. This study proposes a soil–crop collaborative risk assessment model that aims to assess the potential safety risks of heavy metal pollution in farmland soils by considering the concentrations of heavy metals in soils and the accumulation effects of heavy metals in crops. Based on these effects, a decision support system for risk assessment of heavy metal pollution in farmland soil is established, in which technologies such as web-based geographic information system, quick response code, radio frequency identification, and web service are introduced as the bases. The proposed system is composed of a mobile data acquisition terminal (MDAT) and a web-based information system (WIS). The MDAT, which is a portable computerized device running on the Android platform, is used for data acquisition or query, and the WIS is used for risk assessment, data management, and information visualization. The system is employed in some county-level cities in China for risk assessment and supervision of heavy metal pollution in farmlands. The practical application results show that the system provides highly efficient decision support for risk assessment of heavy metal pollution in farmland soils.

TL;DR: In this paper, the authors proposed a logistics delivery route planning method based on geographic positions, which comprises the steps of obtaining the geographic positions of a delivery center and the demand points, and the shortest distances between the delivery center between the demand point and any two demand points.
Abstract: The present invention relates to a logistics delivery route planning method based on geographic positions. The method comprises the steps of obtaining the geographic positions of a delivery center and the demand points, and the shortest distances between the delivery center and the demand points and between any two demand points; according to the geographic positions of the demand points, dividing the demand points into different regions; according to the saved mileages, determining the delivery routes taking the delivery center as the starting and ending point and the demand points as the target points of each region, wherein the saved mileages are the saved shortest actual distances. The logistics delivery route planning method based on the geographic positions firstly divides the demand points of which the straight-line distances are shorter into the regions roughly, then distributes the deliver routes for the demand points of each region according to the actual saved mileages, so that each delivery route is optimal, and further the purpose of reducing the transportation cost is achieved. The present invention also discloses a logistics delivery route planning system based on the geographic positions.

TL;DR: In this paper, the authors focus on the potential uses of pumpkin as an underutilized crop; diversification and development of hybrids, particularly hybridization breeding through diallel mating design; and how implementation of this modern technology would contribute to the breeding of the neglected pumpkin vegetable and stimulate productivity and nourish the world's largest malnourished, deprived, and starved populations.
Abstract: The world’s food and agricultural programs have gradually declined into an unsustainable situation due to challenges such as increase in world population, varied agro-climatic regions, increase temperature, extreme sole-culture growing techniques, and water shortage. A considerable emphasis has been put on few staple food crops coupled with repeated dieting, food scarcity, and essential mineral deficits, frequently inducing dietary disorders. Because relying on staple crops may lead to serious food shortages in the future, we must adjust our dietary habits to include a diverse range of non-staple foods and maximize their use in order to achieve food security and reduce the nutritional gap. To assure healthy meals around the world, an authentic and reasonable strategy is presented to draw additional awareness towards variations in agricultural production techniques and dietary preferences. The EAT-Lancet declaration highlighted the importance of increasing agri-based foods to achieve sustainable health. Expanding overlooked crops with abundant genetic stocks and possibly beneficial characteristics is an approach that might meet food and nutritional security challenges. Although undervalued, pumpkin is a valuable vegetable herbaceous plant that contributes to global food and nutritional security. This crop has already been identified as a revolutionary age crop, balanced food, and more adapted to low soil and atmospheric circumstances than other major crops. This review paper focuses on the potential uses of pumpkin as an underutilized crop; diversification and development of hybrids, particularly hybridization breeding through diallel mating design; and how implementation of this “modern” technology would contribute to the breeding of the neglected pumpkin vegetable and stimulate productivity and nourish the world’s largest malnourished, deprived, and starved populations.
