Abstract

Urban parks have the characteristics of a relatively concentrated population. Seating as products with a high frequency of public use, they have significantly influenced residents’ activities in the epidemic environment. The current design of public seating in parks during the pandemic needs to meet the needs of different people. Thus, the purpose of this research is to meet the needs of the different populations in many aspects of urban park seating objects during the pandemic. This paper integrates literature to develop an urban park seating object strategy in the post-pandemic era. This paper analyses the design factors and design strategies of urban park seating from four aspects based on the current situation of the post-pandemic social environment. The four areas are function, aesthetics, materials, and safe social distance. The results show that the seat’s functional design is crucial. However, aesthetics, materials, and safety cannot be ignored. In addition, people are more concerned about seat safety in the post-pandemic period. Therefore, public seating design strategies for urban parks in the post-pandemic era are developed based on these four aspects.

Abstract

Small and medium-sized manufacturing enterprises in Dongguan use e-commerce and traditional relationship networks to build paths for market opportunity recognition. Taking the company’s monthly average total sales and total capacity as variables, this article employs particle swarm optimization (PSO) to simulate the paths of opportunity recognition in three different modes, namely the single e-commerce mode, the single traditional relationship network and their hybrid mode. The results reveal that: for the single ecommerce mode, the capacity utilization rate is very low; for the single traditional relationship network, changes in learning factor will not affect the choices of the enterprises; for the hybrid mode, the optimal solution of the three models is reached. But there is a substitution between the enterprise’s own learning factor and the group learning factor, which leads to deviation from the optimal solution

Abstract

This article is an introduction to the practices of sponge projects for airports in China. The objective of this paper is to point out the main problems existing in the construction of sponge airports and seek ways to improve the storage volume of airports. Data investigation, technical analysis, and engineering cases are used to conduct the research. The result shows that the main problem in the construction of sponge airport is the lack of effective sponge measures in the airfield area. Addressing the challenges and implementing effective sponge measures in airfield area is feasible and crucial for advancing sponge city concepts in airport construction. The elevation of pavement, particularly in creating sponge storage in unpaved areas, and using a drainage layer for the pavement and the shoulder stands out as a successful approach and should be considered in the design of airfield area projects.

Abstract

Sponge city is an important means of urban stormwater management, and it is also the core concept of green and low-carbon ecological landscape construction.Currently, the rainfall and flooding problems of airports are becoming more and more obvious, and the construction of "sponge airports" is getting more and more attention. However, considering the operational needs of airports, the existing conventional sponge construction ideas cannot be directly applied to airport construction. How to set up a set of reasonable indicators that not only guarantee the safe operation of airports but also meet the requirements of the existing sponge city construction is one of the problems that need to be solved in the process of airport sponge city construction. Taking the third phase expansion project of Guangzhou Baiyun Airport as an example, the design principles of focusing on safety, adapting measures to local conditions, and meeting the overall standards, from the overall consideration of the airport, combined with the land use of each functional zone of the airport, reasonably set the sponge index, so as to provide a reference for the construction of "sponge airport", in order to promote the sustainable development of green and low-carbon construction.

Abstract

In this paper, the strategies to enhance the stability of fuel cell catalyst support are reviewed, with an emphasis on enhancing the graphitization degree (GD) of carbon support. Carbon-based materials are popular as support for O2 reduction reaction cathode catalysts owing to their high specific surface area, remarkable electronic conductivity and low cost. However, long-term operation in the harsh conditions of high acidity, high potential and extreme humidity, can easily lead to electrochemical corrosion of carbon support, thus affecting the activity and life of the catalyst. This paper reviews the judgment method of GD of carbon carrier, the influence of GD on material stability, and the strategy of enhancing the GD value.

Abstract

In southeast China, slope with completely decomposed granite (CDG) soil is susceptible to landslide under heavy rainfall, due to the fissure-rich and slaking characteristics of this kind of soil. In this context, this study attempted to hydraulically improve the CDG soil in a low-carbon manner by using the composite of xanthan gum and guar gum (i.e., two different microbial biopolymers), as an alternative to cement. Hydraulic conductivity of the treated soil was measured using a tailer-made apparatus. Test result shows that the biopolymer content of 2% could lower the conductivity by over 1000 times, and the ratio of 1:1 between Xanthan and guar gums yielded the best performance in general. Application of composite biopolymer to the slope with weathered granitic soil was investigated using the finite element method simulation. Numerical result indicates that the treatment can eliminate the slope failure effectively under rainfall with a hundred-year return period.

Abstract

Reducing the radiation exposure in computed tomography (CT) is always a significant research topic in radiology. Image reconstruction from few-view projection is a reasonable and effective way to decrease the number of rays to lower the radiation exposure. But how to maintain high image reconstruction quality while reducing radiation exposure is a major challenge. To solve this problem, several researchers are absorbed in l0 or l1 regularization based optimization models to deal with it. However, the solution of l1 regularization based optimization model is not sparser than that of l1/2 or l0 regularization, and solving the l0 regularization is more difficult than solving the l1/2 regularization. In this paper, we develop l1/2 regularization for wavelet frames based image reconstruction model to research the few-view problem. First, the existence of the solution of the corresponding model is demonstrated. Second, an alternate direction method (ADM) is utilized to separate the original problem into two subproblems, where the former subproblem about the image is solved using the idea of the proximal mapping, the simultaneous algebraic reconstruction technique (SART) and the projection and contraction (PC) algorithm, and the later subproblem about the wavelet coefficients is solved using the half thresholding (HT) algorithm. Furthermore, the convergence analysis of our method is given by the simulated implementions. Simulated and real experiments confirm the effectiveness of our method.

Abstract

Using zirconium hydroxide as a decontaminant, a kind of self-decontaminating air filter paper that can effectively degrade HD was successfully prepared by impregnating. The morphology and filtration efficiency of the filter paper before and after immersing were compared. The filtration efficiency increased linearly and slowly, with the regression equation: η=0.0001L+99.971. The liquid-solid decontamination reaction of HD on zirconium hydroxide powder and self-decontaminating filter paper conformed to the kinetic of quasi-first-order reaction and found that half-lives were 0.4 h and 2.1 h respectively. Good degradation performance for HD was exhibited and the degradation rate reached more than 99 % in 12 hours. Reaction products were analysed by GC-MS, which displayed that HD was decomposed through the substitution of chlorine and the elimination of H on α-C. The ultimate decontamination products were thiodiglycol and 2-hydroxyethyl vinyl sulfide without erosive toxicity.

Abstract

Research on the propagation characteristics of air-to-water sound transmission is of great importance to the detection of aerial target from underwater. In order to study the propagation characteristics of air-to-water sound transmission in shallow water, an experiment was conducted in the South China Sea in March, 2013. During the experiment, signals transmitted by a hooter hung on a research ship were received by an underwater hydrophone. The source signals were also recorded by a microphone under the hooter. The distance between the hooter and the hydrophone was from 2.4 km to 9.8 km approximately. Data measured during the experiment is analysed in this paper. The transmitted signals and received signals were carefully filtered and calibrated one-by-one. It is shown that the SNRs at 9.8km are up to 12 dB and 18 dB at the frequencies 128 Hz and 256 Hz, respectively. The experimental air-to-water sound transmission loss is estimated up to 9.8 km in range, which has clear oscillation structure. A wave-number integration approach is used to predict the air-to-water transmission losses, which are in good agreement with experimental data.
