Published: December 2020

Abstract
Hierarchical design can not only effectively improve the mechanical properties of lattice structure, but also enhance the multi-functional design ability of lattice structure. Based on pyramid lattice structure, a novel hierarchical pyramid lattice structure was designed to enhance the energy absorption property. The finite element method (FEM) was carried out to explore mechanical behaviors of the hierarchical pyramidal lattice structure. The simulation results showed that the new lattice structure can improve the bearing capacity of the structure, and has a good specific energy absorption capacity. In addition, it can effectively reduce the stress concentration and improve the strength of the structure.

Analysis of Gas Supply & Demand in China and Suggestions for China’s Gas Industry Development
Authors: Yuanqi She , Yang Gao , Mingpeng Li , Shen Yang 
Published: December 2020

Abstract
The global natural gas markets are undergoing profound changes, with the supply and demand patterns in a historical transformation; the market supply and demand keep loose – both the gas traders and trade volume are increasing, the links between regional gas markets are enhanced, the gas pricing and trading mechanisms are diversified, the LNG trade share keeps growing, and the links between regional LNG markets are also strengthened. Influenced by the supply side reform and the accelerated urbanization, among other factors, gas consumption in China is increasing rapidly. However, the consumption of natural gas changes significantly from region to region, affected by the mismatch in gas production and consumption locations, as well as the gas import patterns. With the continuous energy restructuring in China, the gas consumption in different sectors is growing at very different paces. Analysis of the current situation, future trend and characteristics of China’s gas industry indicates that it is in the third stage of fast growth. Natural gas will play an even more important role in the future energy structure. With the continuous growth of gas consumption at home, the existing and expected gas deliverability is still faced with the risk of enlarging shortage in the mid-long term. In consideration of such circumstance, it is suggested that top-level design be strengthened on the national strategic level to seek rational, robust and scale development of the China’s gas industry. Internationally, diversified import channels should be sought to dilute supply risks, cooperation with the Asia-Pacific markets should be enhanced, and establishment of an international gas trading centre should be accelerated. Domestically, construction of a national gas interconnection system and a number of gas hubs should be speeded up, to make the gas industry an important component of the national energy network; the gas pricing mechanism should be established and completed as soon as possible to facilitate scientific allocation of profits and costs for gas production, storage and distribution, and to ultimately promote the sustainable and scale development of the whole chain of China’s gas industry.

Published: December 2020

Abstract
By taking the energy complementation as an idea and the steam methane reforming as well as coal partial gasification and Fischer-Tropsch synthesis as the core technological means, this paper establishes a coal and methane to co-produce liquid fuels and power generation system using an ASPEN PLUS simulator, and realizes that the H2/CO can be adjusted by directly changing the charging rate of raw materials with no need for additional equipment. At the same time, the coal char that has not yet been gasified is burned to provide the needed heat for the reaction of steam methane reforming, which can not only solve the demand of high heat of steam methane reforming, but also realize the gradient utilization of energy, thus reducing the loss in energy. In addition, some Fischer-Tropsch steam is used to generate power to further reduce the energy damage of the system. Two key parameters, namely coal input and Fischer-Tropsch recycle ratio, are discussed and their effects on system performances are analysed. At the optimum condition, the energy efficiency of this novel system reaches 52.5%, and the primary energy saving ratio reaches 30.4%.
Investigating the Effects of Boil-off Gas on Liquefied Energy Carriers During Land Storage and Ocean Transportation
Authors: Al-Breiki Mohammed , Bicer Yusuf 
Published: December 2020

Abstract
As the largest energy production suppliers are in different locations of the world and the demand for energy increases significantly, storage and transportation of large-scale energy with high storage and transportation efficiencies are desired. Large-scale energy is stored and shipped in liquefied forms due to reduction in volume however storage medium in a liquid form with low boiling temperature loses some of its energy because of evaporation, called boil-off gas (BOG), which is caused by a change in temperature between the storage medium and the ambient. Therefore, this study presents sensitivity analysis for three types of energy carriers: liquefied natural gas (LNG), dimethyl-ether (DME), and methanol to store and transport energy in liquid form from an exporting country to an importing country. A calculation method is used to determine the daily BOG rates accounting for storage and transporting for the three liquefied energy carriers. A sensitivity analysis is presented to reveal the effects of changes in duration of land storage and ocean transportation on the total stored and transported masses. LNG has lost 7% of its mass as BOG after 60 day of shipping and this lost percentage is the highest compared to DME and methanol. Due to low mass loses during storage and transportation phases, methanol and DME are potential alternatives for storage and transportation of large energy quantities.
The Potential of Improving Air Quality by Urban Mobility Management: Policy Guidelines and a Case Study
Authors: Badach Joanna 
Published: December 2020

Abstract
There is a growing recognition among planners and policy makers that proper transformation of urban mobility systems is crucial to the reduction of air pollution emission. The main objective of the work was to review the current urban mobility strategies in the city of Gdańsk, Poland in terms of their potential for the improvement of urban air quality. Firstly, general policy guidelines for mobility systems were formulated based on a review of recent relevant studies and existing solutions from various European and Asian cities. Then the main spatial characteristics of the transport system and mobility patterns in Gdańsk were determined and visualised by means of GIS-based tools, supported by the analysis of local urban and environmental planning documents. The current air quality status in Gdańsk was also described. Subsequently, the policies proposed in two documents for the urban mobility management in Gdańsk were identified and cross-compared with the previously reviewed solutions from other cities in terms of air quality improvement. The results showed that the strategies for air pollution mitigation are not integrated with the process of urban planning in Gdańsk to a sufficient degree. Finally, some recommendations were also suggested to improve the current strategies.
Dynamic Optimal Strategies for Multiple Pollutants in Transboundary Pollution Game between Two Asymmetric Regions
Authors: Ling Xingyuan , Meng Weidong , Huang Bo , Wang Chunyang , Li Yuyu 
Published: December 2020

AbstractUnder the fact that there are multiple pollutants, non-cumulative and cumulative pollutants, generated by two adjacent asymmetric regions, which result in transboundary pollution, we proposed a dynamic transboundary pollution treatment model to study how two adjacent asymmetric regions make their pollution treatment strategies under their self-interested behaviors while the pollution of both regions are treated optimally. The optimal investment policies under non-cooperation and cooperation are obtained through theoretic analysis. It is found that only when local governments cooperate to treat transboundary pollution, the damages caused by non-cumulative pollutants to adjacent regions will be taken into their consideration. The capital stock of pollution treatment investment of each region under the non-cooperative treatment is equal to that under the cooperative treatment.

Authors: Shao T , Jin H , Zheng WX 
Published: December 2020

Abstract
The thermal performance of envelope directly restricts the heating energy consumption and indoor thermal environment of rural houses in severe cold regions. However, with the improvement of thermal performance, the construction cost will be greatly affected, which is one of the main factors hindering the implementation of energy saving design for rural houses. The energy saving and economy of whole life cycle should be considered simultaneously when determining the optimal parameters of envelope. This paper, taking the benchmark model of rural houses as research object, the life cycle cost (LCC) as evaluation index, establishes the GenOpt-EnergyPlus optimization platform by coupling EnergyPlus and GenOpt software to carry out the optimization. In the analysis, the insulating layer thickness of exterior wall, roof and ground and the window types are selected as optimization variable. Considering that the length of life span may affect the effective utilization rate of operation and construction cost, three types of life span are set, including 10, 20 and 30 years. Through the analysis, the optimum thickness of insulating layer and the energy saving effect under different conditions were discussed, which provide the basis for the comprehensive optimization of energy saving and economic benefit of rural house’s envelope in severe cold regions of China.

Abstract
In the process of urban development, the more intensive areas are intensive, causing problems of urban congestion, traffic congestion and parking space, and they are the main source of energy consumption. Urban development guided by the development of the mass transit system is widely discussed. However, the problem of improving urban development is not only the construction of the mass transit system, but also the planning of the human environment system, as well as green infrastructure and green transportation. Through literature analysis and field investigation, this study hopes to create a friendly urban environment through the experimental design of roads, buildings and streets around the five power stations (Lilin, Toujiacuo, Songzhu, Jingwu and Wuquan) to truly reduce energy use.

Authors: Feng Shih-Jen , Tung Chung-En 
Published: December 2020

Abstract
The hundred-year prosperity of the mining industry in Jinguashi, Taiwan, introduced the development of new industrial equipment and factory operation models to the settlements of Jinguashi and Shuinandong, and also established a modernized living and social framework. However, changes in global industrial and cultural structures brought on the progression of urbanization, which in turn caused the disuse of abandoned land previously used by the production industry. In the Shuinandong area, the operation of a smeltery polluted the land, damaged the ecology, produced waste and caused the content of heavy metals in the ocean to rise. This environmental destruction continued to impact the natural environment and ecology of the area even after the smeltery closed. Today, with the rise of environmental awareness, people, environmental protection groups and government agencies have begun to pay attention to the impact of “brownfields” around them. In the Shuinandong area, brownfields are mostly used as space for tourism, and not much has been done to restore the environment through ecological methods. Therefore, this study is aimed towards environmental sustainability, and looks at how to preserve the Remains of the Thirteen Levels in Shuinandong while rehabilitating the polluted natural environment and landscapes in the area. This study also establishes ecological restoration assessment indicators that will allow the Shuinandong area to contribute its value for sustainability.

Published: December 2020

Abstract
Dynamic viscosity of silica dioxide suspensions in oils was investigated by acoustical, rotary and capillary methods. An installation has also been created for measuring the viscosity of a liquid at low gradients of the flow velocity, when one can expect that the structure of the liquid change little during elementary acts of viscous flow. It is shown that at low flow rate gradients of the investigated suspensions, an increased value of viscosity is found (relative to the viscometric one), which indicates the structuring of these suspensions with the formation of a supramolecular structure. The observed phenomenon of increased viscosity can be of practical importance for all processes where slow flows prevail.

Published: December 2020

Abstract
Various applications in a multi-tenant architecture based cloud computing comprises various requirements and priorities. Severe failure of a critical application may result if the network is congested in a data center. Hence, it is an important to use an efficient resource provisioning technique for ensuring transfer of high priority data to the other traffics still when the network is congested. Therefore, a new framework of Home Cloud architecture is proposed in this paper to provide an effective and flexible delivery of new applications in an edge-cloud architecture which integrates the two complementary technologies of Software-Defined Networking (SDN) and Network Function Virtualization (NFV). In SDN infrastructure, this presents a priority aware resource placement algorithms by taking into consideration of both host and network resources. The Virtual Machines (VMs) of high priority applications are placed at the strongly connected hosts by introducing the priority aware VM allocation (PAVA) algorithm for reducing the possibility of causing network congestion by other tenants. It also guarantees the critical applications for a required bandwidth by means of allocating bandwidth through the setting of priority queues for each network connection within the network of data center handled by SDN controller. The simulation result of the proposed system shows that the combination of proposed approaches will allocate sufficient resources for high-priority applications within a Home Cloud data centre to meet the QoS requirements.
