A tripartite incentive-enabled edge device resource sharing algorithm was proposed to manage and allocate the shared resources for the “cloud-edge-end” three-tier edge network architecture.Considering the single-point network congestion, network-wide coverage constraint, limited resource constraint and transmission cost constraint, the edge devices were abstracted into different functional nodes to design a convex envelope-based shared node (CESN) selection algorithm to achieve a full-coverage, low-energy shared resource deployment scheme.Secondly, to address the additional cost problem caused by allocating shared resources on edge devices, a tripartite sharing incentive mechanism was designed based on the shared resource leasing model, which guaranteed the long-term and stable participation of edge devices in the sharing mechanism.The simulation results show that the proposed algorithm significantly improves the system energy consumption and node revenue compared to the existing algorithms.

Realizing high-efficiency H2 production under practical, mild conditions is essential to meet the requirements to develop this source of ideal clean, alternative energy; thus, this attracted wide spread interest. Catalytic decomposition of formic acid-formate is one of the most widely studied options to achieve this. Herein, we demonstrate H2 production from HCOOK over Pd/C catalysts, in which a flexible content is allowed by modulating the catalyst preparation conditions, reaction conditions, and catalytic characterizations. This experiment not only includes basic chemical kinetics but also guides students to accumulate innovative consciousness through thinking about the structure-activity relationship of catalysts by structural characterization. In addition, this experiment enriches teaching content, improves teaching efficiency, and exercises students' cooperation ability through modular design and group teaching. This project relies on the National Demonstration Center for Experimental Education to build an inter-school resource sharing platform to realize the sharing of experimental data and characterization results that colleges can then use to freely select the required information to enrich students' experiment reports.

In response to the urgent need for large-scale open collaboration and resource sharing between distributed enterprises under the cloud manufacturing mode, this paper combines evolutionary game theory to establish an incentive mechanism for resource sharing in a distributed environment, and analyzes the evolutionary game trend of resource sharing in different situations. It can be known through theoretical analysis and simulation experiment that total shareable resources, resource sharing level, resource utilization capacity, synergy benefit coefficient, evaluation benefit coefficient, sharing incentive coefficient and speculative penalty coefficient play positive roles in promoting the resource sharing, while the shared cost coefficient plays a negative role and direct benefit level has no effect. There is an inverted U-shaped relationship between the allocation coefficient of synergy benefit and the stable state of resource sharing evolution. This study provides references for promoting distributed resource sharing and accelerating industrial innovation in the future cloud manufacturing mode. [ABSTRACT FROM AUTHOR]

Data in a data center are stored dispersively. The data-oriented task computing disperses big data analysis tasks to different computing nodes. The extensive use of graphics processing unit (GPU) makes it urgent and important to study how to reasonably assign heterogeneous resources to different computing frameworks. We investigate the existing big data computing framework and the GPU computing. Based on the existing cluster resource management model and the GPU management model, we propose a hybrid heterogeneous resource management model that combines CPU resources with GPU resources. The computing nodes manage local resources and implement tasks; the resource management center concertedly manage various computing frameworks. We design and implement a hybrid domain resource sharing and allocation algorithm, which allocates the hybrid domain resources to computing frameworks according to the coordinated use of them so as to fairly share the hybrid domain resources among various computing frameworks and prevent the CPU from too many tasks but the GPU or CPU from resource "hunger". The experimental results show that the allocation algorithm can increase the use of heterogeneous resources and the number of completed tasks by around 15%.

This paper investigated the problem of resource sharing in Internet of vehicles, and proposed an efficient resource sharing method called ERS. The goal of ERS was to improve the successful ratio of resource sharing, to reduce the latency of resource sharing and communication cost, and to improve the transmission efficiency. In order to achieve these goals, ERS designed four strategies, including query strategy, reply strategy, resource replacement strategy, and acknowledgement strategy.This paper conducted the simulation experiment based on the real traces of vehicles. Performance results demonstrate that compared with the other two methods, ERS can achieve higher successful ratio of resource sharing, lower latency, lower communication cost, and higher transmission efficiency. Therefore, ERS is an efficient resource sharing method in Internet of vehicles. [ABSTRACT FROM AUTHOR]

The uneven production capacity among manufacturing industries has led to a lot of potential waste. In order to make the existing resources be used more efficiently, the internet of things platform can help manufacturers communicate with each other, overcome the uneven production capacity and achieve resource sharing. This paper takes two manufacturers as the research objects, discusses the optimal decision-making problem of product transfer between the parties, and establishes a profit optimization model with dual constraints of carbon quota and emission reduction. The optimization decision of capacity sharing between manufacturing industries is discussed respectively in two scenarios (both with sufficient carbon quota, and one sufficient and the other insufficient). At the same time, we verifies the models through using numerical analysis. The results show that inadequate quota can promote enterprises to reduce carbon emission. The abatement costs of enterprise with sufficient capacity and carbon prices have a direct impact on the conditions for the sharing of resources between the two parties. Within the scope of acceptance of corporate abatement costs, emission reductions from companies with sufficient capacity are conducive to the improvement of their competitive advantages.
