This new approach facilitates content distribution as a service of the network with lower delay and higher security in comparison with the current IP network. Applying ICN in current IP infrastructure leads to major complexities. One approach to deploy ICN with less complexity is to integrate ICN with Software Defined Networking(SDN). The SDN controller manages the content distribution, caching, and routing based on the users' requests. In this paper, we extend these context by addressing the ICN topology management problem over the SDN network to achieve an improved user experience as well as network performance. In particular, a centralized controller is designed to construct and manage the ICN overlay. Experimental results indicate that this adopted topology management strategy achieves high performance, in terms of low failure in interest satisfaction and reduced download time compared to a plain ICN.展开更多

文摘The proton exchange membrane fuel cell(PEMFC)and the hydrogen hybrid power system are studied by the fuzzy-PID(FPID)controlmethod and the fuzzy-PID controlmethod by Artificial Bee Colony algorithm(ABCFPID),respectively.The results reveal that compared with the FPID control method,the temperature overshoot of the PEMFC stack under the ABC-FPID control method is decreased by 0.6%.Moreover,the circulating water flow rate within the full operating envelope(about 3 min)is reduced by 19.46 L,which means the ABC-FPID control method is more effective in regulating the stack temperature.Then,the ABC-FPID control method is proposed to study the hydrogen hybrid power system,and the system output power matching,operating characteristic curve of the fuel cell,state of charge(SOC)of the lithium battery,system efficiency and hydrogen demand are obtained.The results indicate that the maximum system efficiency reaches 46.3%,the average system efficiency is 33.8%,and the average hydrogen demand is 0.192 kg/s.Overall,the ABC-FPID control method can efficiently ensure the stability of the fuel cell’s output power,and actively prompt the lithium battery to fulfill the function of“peak shaving and valley filling”under variable load power conditions.

文摘The recovery and utilization of ubiquitous low-grade heat are crucial for mitigating the fossil energy crisis.However,uncontrolled spontaneous heat dissipation limits its practical application.Inspired by skeletal muscle thermogenesis,we develop a compressible wood phase change gel with mechano-controlled heat release by infiltrating xylitol gel into wood aerogel.The xylitol gel can store recovered low-grade heat for at least 1 month by leveraging its inherent energy barrier.The hierarchically aligned lamellar structure of wood aerogel facilitates mechanical adaptation,hydrogen bond formation,and energy dissipation between the wood aerogel and the xylitol gel,increasing the compressive strength and toughness of wood phase change gel fivefold compared to xylitol gel.This enhancement effect enables repetitive contact-separation motions between the wood phase change gel and the substrate during radial compression,overcoming the energy barrier and releasing approximately 178.6 J g−1 of heat.As a proof-of-concept,the wood phase change gel serves as the hot side in a thermoelectric generator,providing about 2.13 W m^(−2) of clean electricity by the controlled utilization of recovered solar heat.This study presents a sustainable method to achieve off-grid electricity generation through the controlled utilization of recovered low-grade heat.

文摘In the process of civil engineering construction, often requires the relevant construction units and staff to improve the understanding of the project cost control and management, and do a good job of civil engineering cost control and management. However, in the actual process of cost management, due to the influence of various factors, most managers cannot well carry out cost control, often there are various problems, which seriously affects the smooth development of civil engineering cost management work, but also difficult to achieve good cost control effect. Therefore, this requires the relevant managers to be able to pay attention to, combined with the actual situation to take effective cost control measures, better promote the good development of China's construction enterprises.
文摘In recent years, in the process of the modernization of the construction industry, the project cost has become the focus of attention. In any project implementation, the project cost management can not be ignored. At present, although many project owners have realized the importance of the information construction of project cost management, and also carried out a wealth of exploration and practice, there are still many deficiencies in the information construction of project cost management. In the future development process, the cost management in the engineering field should change the traditional concept and mode, carry out the corresponding information innovation, and improve the overall level of project cost information according to the lack of cost management information construction.
文摘Information-Centric Networking(ICN) has recently emerged as a result of the increased demand to access contents regardless of their location in the network services. This new approach facilitates content distribution as a service of the network with lower delay and higher security in comparison with the current IP network. Applying ICN in current IP infrastructure leads to major complexities. One approach to deploy ICN with less complexity is to integrate ICN with Software Defined Networking(SDN). The SDN controller manages the content distribution, caching, and routing based on the users' requests. In this paper, we extend these context by addressing the ICN topology management problem over the SDN network to achieve an improved user experience as well as network performance. In particular, a centralized controller is designed to construct and manage the ICN overlay. Experimental results indicate that this adopted topology management strategy achieves high performance, in terms of low failure in interest satisfaction and reduced download time compared to a plain ICN.

文摘In order to solve the problems of poor informationflow,low energy utilization rate and energy consumption data reuse in the heavy equipment industrial park,the Internet of Things(IoT)technology is applied to construct the intelligent energy management and control system(IEMCS).The application architecture and function module planning are analyzed and designed.Furthermore,the IEMCS scheme is not unique due to the fuzziness of customer demand and the understanding deviation of designer to customer demand in the design stage.Scheme assessment is of great significance for the normal subsequent implementation of the system.A fuzzy assessment method for IEMCS scheme alternatives is proposed to achieve scheme selection.Fuzzy group decision using triangular fuzzy number to express the vague assessment of experts is adopted to determine the index value.TOPSIS is modified by replacing Euclidean distance with contact vector distance in IEMCS scheme alternative assessment.An experiment with eight IEMCS scheme alternatives in a heavy equipment industrial park is given for the validation.The experiment result shows that eight IEMCS scheme alternatives can be assessed.Through the comparisons with other methods,the reliability of the results obtained by the proposed method is discussed.
