TRANSLATING THE MULTI-ACTOR APPROACH TO RESEARCH INTO PRACTICE USING A WORKSHOP APPROACH FOCUSING ON SPECIES MIXTURES

《农业科学与工程前沿(英文)》 2021年 第8卷 第3期   页码 460-473 doi: 10.15302/J-FASE-2021416

摘要:

The EIP-Agri multiactor approach was exemplified during a 3-day workshop with 63 project participants from the EU H2020 funded project “Redesigning European cropping systems based on species MIXtures”. The objective was to share firsthand experience of participatory research among researchers who were mostly not familiar with this approach. Workshop participants were divided into smaller multidisciplinary groups and given the opportunity to interact with representatives from eight actor positions in the value chain of the agrifood cooperative Terrena located in Western France. The four stages of the workshop were: (1) key actor interviews, (2) sharing proposed solutions for overcoming barriers, and (3) developing possible interdisciplinary concepts. Expressions of frustration were recorded serving both as a motivation for group members to become more aware of the scientific concerns and practices of their colleagues, as well as a recognition that some researchers have better skills integrating qualitative approaches than others. Nevertheless, the workshop format was an effective way to gain a common understanding of the pertinent issues that need to be addressed to meet overall multiactor-approach objectives. Working with the actor networks was identified and emphasized as a means to overcome existing barriers between academia and practice in order to coproduce a shared vision of the benefits of species mixture benefits.

摘要:

从车联网中挖掘知识,利用高效率低成本的知识共享可以提高自动驾驶汽车的决策能力。然而,在高速移动的环境中,如何确保本地数据学习模型高效率的同时防止隐私泄露是一项挑战。为了在知识共享中保护数据隐私并提高数据学习效率,提出了一种异步联邦宽度学习(FBL)框架,该框架将宽度学习(BL)集成到联邦学习(FL)中。在FBL中,设计了一个宽度全连接模型(BFCM)作为训练客户端数据的本地模型。为了提高知识共享的无线信道质量并降低参与客户端的通信和计算成本,构建了一个针对FBL的联合资源分配和智能超表面(RIS)配置的优化框架。该问题被解耦为两个凸子问题。为了提高FBL的资源调度效率,利用双重Davidon–Fletcher–Powell(DDFP)优化算法来解决时隙分配和RIS配置问题。在资源调度结果的基础上,在FBL中设计了一种基于联邦激励学习的奖励分配算法,对客户端的成本进行补偿。仿真结果表明,所提出的FBL框架在IoV中知识共享的效率、准确性和成本方面相较对比模型能取得更好的性能。

Reducing CO emissions from the rebalancing operation of the bike-sharing system in Beijing

《工程管理前沿(英文)》 2023年 第10卷 第2期   页码 262-284 doi: 10.1007/s42524-021-0168-y

摘要: With the development of the bike-sharing system (BSS) and the introduction of green and low carbon development, the environmental impacts of BSS had received increasing attention in recent years. However, the emissions from the rebalancing of BSS, where fossil-fueled vehicles are commonly used, are usually neglected, which goes against the idea of green travel in a sharing economy. Previous studies on the bike-sharing rebalancing problem (BRP), which is considered NP-hard, have mainly focused on algorithm innovation instead of improving the solution model, thereby hindering the application of many existing models in large-scale BRP. This study then proposes a method for optimizing the CO2 emissions from BRP and takes the BSS of Beijing as a demonstration. We initially analyze the spatial and temporal characteristics of BSS, especially the flow between districts, and find that each district can be independently rebalanced. Afterward, we develop a rebalancing optimization model based on a partitioning strategy to avoid deciding the number of bikes being loaded or unloaded at each parking node. We then employ the tabu search algorithm to solve the model. Results show that (i) due to over launch and lack of planning in rebalancing, the BSS in Beijing shows great potential for optimization, such as by reducing the number of vehicle routes, CO2 emissions, and unmet demands; (ii) the CO2 emissions of BSS in Beijing can be reduced by 57.5% by forming balanced parking nodes at the end of the day and decreasing the repetition of vehicle routes and the loads of vehicles; and (iii) the launch amounts of bikes in specific districts, such as Shijingshan and Mentougou, should be increased.

Data sharing mechanism of various mineral resources based on blockchain

Yili REN, Jia LIANG, Jian SU, Gang CAO, He LIU

《工程管理前沿(英文)》 2020年 第7卷 第4期   页码 592-604 doi: 10.1007/s42524-020-0132-2

摘要: Basins with various mineral resources coexisting and enriching often occupy an important strategic position. The exploration of various mineral resources is repetitive at present due to unshared data and imperfect management mechanism. This situation greatly increases the cost of energy exploitation in the country. Traditional data-sharing mode has several disadvantages, such as high cost, difficulty in confirming the right of data, and lack of incentive mechanism, which make achieving real data sharing difficult. In this paper, we propose a data-sharing mechanism based on blockchain and provide implementation suggestions and technical key points. Compared with traditional data-sharing methods, the proposed data-sharing mechanism can realize data sharing, ensure data quality, and protect intellectual property. Moreover, key points in the construction are stated in the case study section to verify the feasibility of the data-sharing system based on blockchain proposed in this paper.

Interaction behavior and load sharing pattern of piled raft using nonlinear regression and LM algorithm-based

《结构与土木工程前沿(英文)》 2021年 第15卷 第5期   页码 1181-1198 doi: 10.1007/s11709-021-0744-6

摘要: In the recent era, piled raft foundation (PRF) has been considered an emergent technology for offshore and onshore structures. In previous studies, there is a lack of illustration regarding the load sharing and interaction behavior which are considered the main intents in the present study. Finite element (FE) models are prepared with various design variables in a double-layer soil system, and the load sharing and interaction factors of piled rafts are estimated. The obtained results are then checked statistically with nonlinear multiple regression (NMR) and artificial neural network (ANN) modeling, and some prediction models are proposed. ANN models are prepared with Levenberg–Marquardt (LM) algorithm for load sharing and interaction factors through backpropagation technique. The factor of safety (FS) of PRF is also estimated using the proposed NMR and ANN models, which can be used for developing the design strategy of PRF.

从资源共享到服务共享:透明计算的机遇与挑战

张尧学,周悦芝

《中国工程科学》 2009年 第11卷 第8期   页码 10-17

摘要:

随着计算机和网络技术以及应用的不断快速发展,计算模式从最初的以主机计算为主,发展到以桌面(PC)计算为主,再发展到现在的以网络计算为主,乃至普适计算。然而,迄今为止的计算模式还是遵循以单机或单机联合为基础的单机思维模式,因此,目前的计算模式还是一种以“资源共享”为主要特征的计算。在网络和普适计算的新时代,用户关心的主要是服务和服务共享,计算机也将从以“资源共享”为特征的计算过渡到以“服务共享”为特征的计算。笔者提出一种适应于“服务共享”的计算模式——透明计算,并对其概念、体系结构及相关关键技术进行介绍。此外,还对透明计算的未来发展及影响进行展望。

Collaborative adoption of blockchain technology: A supply chain contract perspective

《工程管理前沿(英文)》 2023年 第10卷 第1期   页码 121-142 doi: 10.1007/s42524-022-0239-8

摘要: The outbreak of COVID-19 has significantly affected the development of enterprises. In the post-pandemic era, blockchain technology has become one of the important technologies to help enterprises quickly gain market competitiveness. The heavy investment required of supply chain stakeholders to employ blockchain technology has hindered its adoption and application. To tackle this issue, this study aims to facilitate the adoption of blockchain technology in a supply chain consisting of a core enterprise and a small/medium-sized enterprise through an effective supply chain contract. We analyze the performance of a cost-sharing (CS) contract and a revenue-sharing (RS) contract and propose a new hybrid CS-RS contract for better performance. We conduct comparative analyses of the three contracts and find that the hybrid CS-RS contract can more effectively incentivize both parties to reach the highest level of blockchain technology adoption and achieve supply chain coordination.

摘要:

Knowledge representation is the core of artificial intelligence research. Knowledge representation methods include predicate logic, semantic network, computer programming language, database, mathematical model, graphics language, natural language, etc. To establish the intrinsic link between various knowledge representation methods, a unified knowledge representation model is necessary. According to ontology, system theory, and control theory, a standard model of knowledge representation that reflects the change of the objective world is proposed. The model is composed of input, processing, and output. This knowledge representation method is not a contradiction to the traditional knowledge representation method. It can express knowledge in terms of multivariate and multidimensional. It can also express process knowledge, and at the same time, it has a strong ability to solve problems. In addition, the standard model of knowledge representation provides a way to solve problems of non-precision and inconsistent knowledge.

摘要: The lateral performance of timber-steel hybrid shear wall systems with regard to the interaction between the steel frame and the infill wood shear wall was investigated in this paper. A numerical model for the timber-steel hybrid shear wall system was developed and verified against test results. Design parameters, such as the lateral infill-to-frame stiffness ratio and the arrangements of wood-steel bolted connections were studied using the numerical model. Some design recommendations were also proposed based on the parametric analysis. In the hybrid shear wall system, the infill wood wall was found to resist a major part of the lateral load within relatively small wall drifts, and then the steel frame provided more lateral resistance. Under seismic loads, the infill wood wall could significantly reduce the inter-story drift of the hybrid system, and a complementary effect between the infill wood wall and the steel frame was observed through different lateral load resisting mechanisms, which provided robustness to the hybrid shear wall systems.
