A Time-Driven Data Placement Strategy for a Scientific Workflow Combining Edge Computing and Cloud Computing

Abstract: Compared to traditional distributed computing environments such as grids, cloud computing provides a more cost-effective way to deploy scientific workflows. Each task of a scientific workflow requires several large datasets that are located in different datacenters, resulting in serious data transmission delays. Edge computing reduces the data transmission delays and supports the fixed storing manner for scientific workflow private datasets, but there is a bottleneck in its storage capacity. It is a challenge to combine the advantages of both edge computing and cloud computing to rationalize the data placement of scientific workflow, and optimize the data transmission time across different datacenters. In this study, a self-adaptive discrete particle swarm optimization algorithm with genetic algorithm operators (GA-DPSO) was proposed to optimize the data transmission time when placing data for a scientific workflow. This approach considered the characteristics of data placement combining edge computing and cloud computing. In addition, it considered the factors impacting transmission delay, such as the bandwidth between datacenters, the number of edge datacenters, and the storage capacity of edge datacenters. The crossover and mutation operators of the genetic algorithm were adopted to avoid the premature convergence of traditional particle swarm optimization algorithm, which enhanced the diversity of population evolution and effectively reduced the data transmission time. The experimental results show that the data placement strategy based on GA-DPSO can effectively reduce the data transmission time during workflow execution combining edge computing and cloud computing.

Innovations for healthier processed meats

Abstract: Meat and meat products are generally recognised as good sources of high biological-value proteins, group B vitamins, minerals and trace elements as well as some other bioactive compounds. However, the image to consumers is relatively negative due to their involvement in prevalent diseases of Western societies like cardiovascular diseases, cancer and obesity. Recent innovations in the meat industry are addressed towards the production of healthier meats and processed meats. The strategies are based on either reducing the content of unhealthy substances (i.e. less added sodium chloride, less nitrate and nitrite) or improving the content of substances with healthy benefits (i.e. natural antioxidants, omega-3 fatty acids, probiotics and bioactive peptides).
