has been designated as a national strategy in China. Analyzing its spatial evolution characteristics is crucial for devising relevant development strategies. This paper enhances the gravitational model by using temporal distance as a factor. It applies this improved model to assess the economic interconnection and concentration level of each geographical unit within the Chengdu-Chongqing urban agglomeration between 2011 and 2019. On this basis, this paper examines the spatial correlation characteristics of economic agglomeration intensity and urban-rural development equalization by employing spatial autocorrelation analysis. The study findings indicate that the spatial integration in the Chengdu-Chongqing urban agglomeration is currently in the "point-axis" development stage. The spatial organization structure is becoming more flattened, and there is a stronger economic connection between the core of the urban agglomeration and the peripheral areas. The integration of the Chengdu-Chongqing urban agglomeration is currently hindered by conflicting interests and institutional heterogeneity between Chengdu and Chongqing. Additionally, the connections between the relatively secondary spatial units are largely loose and weak. The strength and scale of economic ties and the level of urban-rural equilibrium among spatial units within the Chengdu-Chongqing urban agglomeration have increased, but regional imbalances have continued to widen, and such positive and negative changes have been characterized by the spatial and temporal synergistic evolution of the "core-periphery". Ultimately, this paper presents planning ideas for the future integration development of the Chengdu-Chongqing urban agglomeration, drawing from the findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integration" title="integration">integration</a>, <a href="https://publications.waset.org/abstracts/search?q=planning%20strategy" title=" planning strategy"> planning strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20organization" title=" space organization"> space organization</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20evolution" title=" space evolution"> space evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20agglomeration" title=" urban agglomeration"> urban agglomeration</a> </p> <a href="https://publications.waset.org/abstracts/179163/study-on-the-spatial-evolution-characteristics-of-urban-agglomeration-integration-in-china-the-case-of-chengdu-chongqing-urban-agglomeration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179163.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">50</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7226</span> A Study of the Interactions between the Inter-City Traffic System and the Spatial Structure Evolution in the Yangtze River Delta from Time and Space Dimensions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Cong">Zhang Cong</a>, <a href="https://publications.waset.org/abstracts/search?q=Cai%20Runlin"> Cai Runlin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jia%20Fengjiao"> Jia Fengjiao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The evolution of the urban agglomeration spatial structure requires strong support of the inter-city traffic system. And the inter-city traffic system can not only meet the demand of the urban agglomeration transportation but also guide the economic development. To correctly understand the relationship between inter-city traffic planning and urban agglomeration can help the urban agglomeration coordinated developing with the inter-city traffic system. The Yangtze River Delta is one of the most representative urban agglomerations in China with strong economic vitality, high city levels, diversified urban space form, and improved transport infrastructure. With the promotion of industrial division in the Yangtze River Delta and the regional travel facilitation brought by inter-city traffic, the urban agglomeration is characterized by highly increasing of inter-city transportation demand, the urbanization of regional traffic, adjacent regional transportation links breaking administrative boundaries, the networked channels and so on. Therefore, the development of inter-city traffic system presents new trends and challenges. This paper studies the interactions between inter-city traffic system and regional economic growth, regional factor flow, and regional spatial structure evolution in the Yangtze River Delta from two dimensions of time and space. On this basis, the adaptability of inter-city traffic development mode and urban agglomeration space structure is analyzed. First of all, the coordination between urban agglomeration planning and inter-city traffic planning is judged from the planning level. Secondly, the coordination between inter-city traffic elements and industries and population distributions is judged from the perspective of space. Finally, the coordination of the cross-regional planning and construction of inter-city traffic system is judged. The conclusions can provide an empirical reference for intercity traffic planning in Yangtze River Delta region and other urban agglomerations, and it is also of great significance to optimize the allocation of urban agglomerations and the overall operational efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evolution" title="evolution">evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-city%20traffic%20system" title=" inter-city traffic system"> inter-city traffic system</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20structure" title=" spatial structure"> spatial structure</a> </p> <a href="https://publications.waset.org/abstracts/90357/a-study-of-the-interactions-between-the-inter-city-traffic-system-and-the-spatial-structure-evolution-in-the-yangtze-river-delta-from-time-and-space-dimensions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90357.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">312</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7225</span> The Relationship between Metropolitan Space and Spatial Distribution of Main Innovative Actors: The Case of Yangtze Delta Metropolitan in China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun%20Zhou">Jun Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Xingping%20Wang"> Xingping Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Milbourne"> Paul Milbourne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Evidences in the world shows that the industry and population have being greatly concentrated in metropolitan regions which is getting to be the most important area for the economic power and people living standard in the future. In the meanwhile, the relevant innovation theories of Agglomeration, New Industrial Geography and Modern Evolutionary innovation prove that the reason why the agglomeration in world-class city and metropolitan areas and also verify innovation is the key point for the development of metropolis. The primary purpose of this paper is to analyze the geographical spatial characteristics of innovative subjects which contain firm, university, research institution, government and intermediary organ in metropolis throughout the amount data analysis in Yangtze River Metropolis in China. The results show three main conclusions. The first is different subjects in different regions have different spatial characteristics. The second one is different structure and pattern between the subjects also can produce different innovative effect. The last but not the least is agglomeration of innovative subjects’ is not only influenced by the innovative network or local policies but also affected by the localized industry characteristics and culture which are getting to be the most important crucial factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metropolitan%20development" title="metropolitan development">metropolitan development</a>, <a href="https://publications.waset.org/abstracts/search?q=innovative%20subject" title=" innovative subject"> innovative subject</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial" title=" spatial"> spatial</a>, <a href="https://publications.waset.org/abstracts/search?q=Yangtze%20River%20Metropolis" title=" Yangtze River Metropolis"> Yangtze River Metropolis</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a> </p> <a href="https://publications.waset.org/abstracts/19257/the-relationship-between-metropolitan-space-and-spatial-distribution-of-main-innovative-actors-the-case-of-yangtze-delta-metropolitan-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19257.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7224</span> Borrowing Performance: A Network Connectivity Analysis of Second-Tier Cities in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E%C4%9Fin%C3%A7%20Simay%20Ert%C3%BCrk">Eğinç Simay Ertürk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferhan%20Gezi%CC%87ci%CC%87"> Ferhan Gezi̇ci̇</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The decline of large cities and the rise of second-tier cities have been observed as a global trend with significant implications for economic development and urban planning. In this context, the concepts of agglomeration shadow and borrowed size have gained importance as network externalities that affect the growth and development of surrounding areas. Istanbul, Izmir, and Ankara are Turkey's most significant metropolitan cities and play a significant role in the country's economy. The surrounding cities rely on these metropolitan cities for economic growth and development. However, the concentration of resources and investment in a single location can lead to agglomeration shadows in the surrounding areas. On the other hand, network connectivity between metropolitan and second-tier cities can result in borrowed function and performance, enabling smaller cities to access resources, investment, and knowledge they would not otherwise have access. The study hypothesizes that the network connectivity between second-tier and metropolitan cities in Turkey enables second-tier cities to increase their urban performance by borrowing size through these networks. Regression analysis will be used to identify specific network connectivity parameters most strongly associated with urban performance. Network connectivity will be measured with parameters such as transportation nodes and telecommunications infrastructure, and urban performance will be measured with an index, including parameters such as employment, education, and industry entrepreneurship, with data at the province levels. The contribution of the study lies in its research on how networking can benefit second-tier cities in Turkey. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20connectivity" title="network connectivity">network connectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=borrowed%20size" title=" borrowed size"> borrowed size</a>, <a href="https://publications.waset.org/abstracts/search?q=agglomeration%20shadow" title=" agglomeration shadow"> agglomeration shadow</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20cities" title=" secondary cities"> secondary cities</a> </p> <a href="https://publications.waset.org/abstracts/174865/borrowing-performance-a-network-connectivity-analysis-of-second-tier-cities-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174865.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7223</span> Local Government Digital Attention and Green Technology Innovation: Analysis Based on Spatial Durbin Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xin%20Wang">Xin Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaoqun%20Ma"> Chaoqun Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Zheng%20Yao"> Zheng Yao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although green technology innovation faces new opportunities and challenges in the digital era, its theoretical research remains limited. Drawing on the attention-based view, this study employs the spatial Durbin model to investigate the impact of local government digital attention and digital industrial agglomeration on green technology innovation across 30 Chinese provinces from 2011 to 2021, as well as the spatial spillover effects present. The results suggest that both government digital attention and digital industrial agglomeration positively influence green technology innovation in local and neighboring provinces, with digital industrial agglomeration exhibiting a positive moderating effect on this direct local and indirect spatial spillover relationship.

This paper concerns the non-stationarity and the autocorrelation (with Moran’s I index of 0.75) of the AOD in Wuhan agglomeration (WHA), in central China, uses the geographically weighted regression (GRW) to identify the spatial relationship of AOD and its impact factors. The 3 km AOD product of Moderate Resolution Imaging Spectrometer (MODIS) is used in this study. Beyond the economic-social factor, land use density factors, vegetable cover, and elevation, the landscape metric is also considered as one factor. The results suggest that the GWR model is capable of dealing with spatial varying relationship, with R square, corrected Akaike Information Criterion (AICc) and standard residual better than that of ordinary least square (OLS) model. The results of GWR suggest that the urban developing, forest, landscape metric, and elevation are the major driving factors of AOD. Generally, the higher AOD trends to located in the place with higher urban developing, less forest, and flat area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerosol%20optical%20depth" title="aerosol optical depth">aerosol optical depth</a>, <a href="https://publications.waset.org/abstracts/search?q=geographically%20weighted%20regression" title=" geographically weighted regression"> geographically weighted regression</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20change" title=" land use change"> land use change</a>, <a href="https://publications.waset.org/abstracts/search?q=Wuhan%20agglomeration" title=" Wuhan agglomeration"> Wuhan agglomeration</a> </p> <a href="https://publications.waset.org/abstracts/81331/impact-factor-analysis-for-spatially-varying-aerosol-optical-depth-in-wuhan-agglomeration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81331.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7221</span> Ultrasonic Agglomeration of Protein Matrices and Its Effect on Thermophysical, Macro- and Microstructural Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Rivera-Tobar%20Mario%20Perez-Won">Daniela Rivera-Tobar Mario Perez-Won</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Lemus-Mondaca"> Roberto Lemus-Mondaca</a>, <a href="https://publications.waset.org/abstracts/search?q=Gipsy%20Tabilo-Munizaga"> Gipsy Tabilo-Munizaga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Different dietary trends worldwide seek to consume foods with anti-inflammatory properties, rich in antioxidants, proteins, and unsaturated fatty acids that lead to better metabolic, intestinal, mental, and cardiac health. In this sense, food matrices with high protein content based on macro and microalgae are an excellent alternative to meet the new needs of consumers. An emerging and environmentally friendly technology for producing protein matrices is ultrasonic agglomeration. It consists of the formation of permanent bonds between particles, improving the agglomeration of the matrix compared to conventionally agglomerated products (compression). Among the advantages of this process are the reduction of nutrient loss and the avoidance of binding agents. The objective of this research was to optimize the ultrasonic agglomeration process in matrices composed of Spirulina (Arthrospira platensis) powder and Cochayuyo (Durvillae Antartica) flour, by means of the response variable (Young's modulus) and the independent variables were the process conditions (percentage of ultrasonic amplitude: 70, 80 and 90; ultrasonic agglomeration times and cycles: 20, 25 and 30 seconds, and 3, 4 and 5). It was evaluated using a central composite design and analyzed using response surface methodology. In addition, the effects of agglomeration on thermophysical and microstructural properties were evaluated. It was determined that ultrasonic compression with 80 and 90% amplitude caused conformational changes according to Fourier infrared spectroscopy (FTIR) analysis, the best condition with respect to observed microstructure images (SEM) and differential scanning calorimetry (DSC) analysis, was the condition of 90% amplitude 25 and 30 seconds with 3 and 4 cycles of ultrasound. In conclusion, the agglomerated matrices present good macro and microstructural properties which would allow the design of food systems with better nutritional and functional properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20agglomeration" title="ultrasonic agglomeration">ultrasonic agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20properties%20of%20food" title=" physical properties of food"> physical properties of food</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20matrices" title=" protein matrices"> protein matrices</a>, <a href="https://publications.waset.org/abstracts/search?q=macro%20and%20microalgae" title=" macro and microalgae"> macro and microalgae</a> </p> <a href="https://publications.waset.org/abstracts/172168/ultrasonic-agglomeration-of-protein-matrices-and-its-effect-on-thermophysical-macro-and-microstructural-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172168.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7220</span> Fluidized-Bed Combustion of Biomass with Elevated Alkali Content: A Comparative Study between Two Alternative Bed Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Ninduangdee">P.

However, due to elevated alkali content in biomass ash, this oil palm residue shows high tendency to bed agglomeration in a fluidized-bed combustion system using conventional bed material (silica sand). In this study, palm kernel shell was burned in the conical fluidized-bed combustor (FBC) using alumina and dolomite as alternative bed materials to prevent bed agglomeration. For each bed material, the combustion tests were performed at 45kg/h fuel feed rate with excess air within 20–80%. Experimental results revealed rather weak effects of the bed material type but substantial influence of excess air on the behaviour of temperature, O2, CO, CxHy, and NO inside the reactor, as well as on the combustion efficiency and major gaseous emissions of the conical FBC. The optimal level of excess air ensuring high combustion efficiency (about 98.5%) and acceptable level of the emissions was found to be about 40% when using alumina and 60% with dolomite. By using these alternative bed materials, bed agglomeration can be prevented when burning the shell in the proposed conical FBC. However, both bed materials exhibited significant changes in their morphological, physical and chemical properties in the course of the time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20kernel%20shell" title="palm kernel shell">palm kernel shell</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized-bed%20combustion" title=" fluidized-bed combustion"> fluidized-bed combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20bed%20materials" title=" alternative bed materials"> alternative bed materials</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20and%20emission%20performance" title=" combustion and emission performance"> combustion and emission performance</a>, <a href="https://publications.waset.org/abstracts/search?q=bed%20agglomeration%20prevention" title=" bed agglomeration prevention"> bed agglomeration prevention</a> </p> <a href="https://publications.waset.org/abstracts/3746/fluidized-bed-combustion-of-biomass-with-elevated-alkali-content-a-comparative-study-between-two-alternative-bed-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">250</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7219</span> The Evolution of Spatio-Temporal Patterns of New-Type Urbanization in the Central Plains Economic Region in China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun%20fang">Sun fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Wenxin"> Zhang Wenxin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper establishes an evaluation index system for spatio-temporal patterns of urbanization, with the county as research unit. We use the Entropy Weight method, coefficient variance, the Theil index and ESDA-GIS to analyze spatial patterns and evolutionary characteristics of New-Type Urbanization in the Central Plains Economic Region (CPER) between 2000 and 2011. Results show that economic benefit, non-agricultural employment level and level of market development are the most important factors influencing the level of New-Type Urbanization in the CPER; overall regional differences in New-Type Urbanization have declined while spatial correlations have increased from 2000 to 2011. The overall spatial pattern has changed little, however; differences between the western and eastern areas of the CPER are clear, and the pattern of a strong west and weak east did not change significantly over the study period. Areas with high levels of New-Type Urbanization were mostly distributed along the Beijing-Guangzhou and LongHai Railways on both sides, a new influx of urbanization was tightly clustered around ZhengZhou in the Central Henan Urban Agglomeration, but this trend was found to be weakening slightly. The level of New-Type Urbanization in municipal districts was found to be much higher than it was in the county generally. Provincial borders experienced a lower rate of growth and a lower level of New-Type Urbanization than did any other areas, consistently forming clusters of cold spots and sub-cold spots. The analysis confirms that historical development, location, and diffusion effects of urban agglomeration are the main drivers of changes in New-Type Urbanization patterns in CPER. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new-type%20urbanization" title="new-type urbanization">new-type urbanization</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20pattern" title=" spatial pattern"> spatial pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20plains%20economic%20region" title=" central plains economic region"> central plains economic region</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20evolution" title=" spatial evolution"> spatial evolution</a> </p> <a href="https://publications.waset.org/abstracts/63730/the-evolution-of-spatio-temporal-patterns-of-new-type-urbanization-in-the-central-plains-economic-region-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63730.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7218</span> Right of the City and Urban Boundaries: An Analytical Study of the Settlements in the Border of the River ‘Riachuelo’ on the Urban Agglomeration of Buenos Aires, Argentina</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mitchell%20De%20Sousa">Mitchell De Sousa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The city of Buenos Aires and its agglomeration concentrates more than the thirty percent of the Argentine population. Historically, the political governments (essentially during the neoliberal ones) focused all the equipment, investment, progress on the north of the city since it is the place where all the financial, core services, and the main country harbor is. The south part of the town and all the cities around the south portion of it is has been, historically, where are concentrated the more vital unfulfilled needs of this population. The river that cross over the urban agglomeration of Buenos Aires, the Matanza-Riachuelo, has been historically a place of urban segregation since it is located south of the main town. From the post-colonial times, the river has been officially a place that separates the jurisdiction of the city of Buenos Aires with some of the towns that were built around the urban agglomeration. Since its place has never been treated as a whole and has always been treated as a boundary, there is always been a focus for factories to dispose its waste and an attractive place for a large portion of the underclasses to settled down there, occupying illegally the previous terrains that were once from the railway, now abandoned. Regarding those issues and adding a one more problematic one, those who lives beyond the boundary has few access to enter the main capital city. A few bridges connect some portions of it over the Matanza Riachuelo River, which there is also a limited accessibility to the main city from the south. Because of such, the main entrances to the town are always collapsed by all the services that the urban agglomeration offer (from buses to trains and individual cars). Beyond all the enlisted problems, the contamination of the river makes it one of the most contaminated rivers on the entire world. Those who lives in the settlements are in there for themselves, so the fight from them to their right of the city and their claims to the state for intervention in the urban coast is one of the most promising discussions surrounding this place of this urban agglomeration. The study focuses on the perception of those who lives in this boundary through interviews and collective experiences and is a part of a more developed project in the University of Buenos Aires study called ‘Urban landscape and a sustainable study through the interdisciplinary. Urban strategies on city borders’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buenos%20Aires" title="Buenos Aires">Buenos Aires</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape" title=" landscape"> landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility" title=" mobility"> mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=popular%20sectors" title=" popular sectors"> popular sectors</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20segregation" title=" urban segregation"> urban segregation</a> </p> <a href="https://publications.waset.org/abstracts/86743/right-of-the-city-and-urban-boundaries-an-analytical-study-of-the-settlements-in-the-border-of-the-river-riachuelo-on-the-urban-agglomeration-of-buenos-aires-argentina" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86743.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7217</span> Research on the Function Optimization of China-Hungary Economic and Trade Cooperation Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wenjuan%20Lu">Wenjuan Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> China and Hungary have risen from a friendly and comprehensive cooperative relationship to a comprehensive strategic partnership in recent years, and the economic and trade relations between the two countries have developed smoothly. As an important country along the ‘Belt and Road’, Hungary and China have strong economic complementarities and have unique advantages in carrying China's industrial transfer and economic transformation and development. The construction of the China-Hungary Economic and Trade Cooperation Zone, which was initiated by the ‘Sino-Hungarian Borsod Industrial Zone’ and the ‘Hungarian Central European Trade and Logistics Cooperation Park’ has promoted infrastructure construction, optimized production capacity, promoted industrial restructuring, and formed brand and agglomeration effects. Enhancing the influence of Chinese companies in the European market has also promoted economic development in Hungary and even in Central and Eastern Europe. However, as the China-Hungary Economic and Trade Cooperation Zone is still in its infancy, there are still shortcomings such as small scale, single function, and no prominent platform. In the future, based on the needs of China's cooperation with ‘17+1’ and China-Hungary cooperation, on the basis of appropriately expanding the scale of economic and trade cooperation zones and appropriately increasing the number of economic and trade cooperation zones, it is better to focus on optimizing and adjusting its functions and highlighting different economic and trade cooperation. The differentiated function of the trade zones strengthens the multi-faceted cooperation of economic and trade cooperation zones and highlights its role as a platform for cooperation in information, capital, and services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%E2%80%98One%20Belt" title="‘One Belt">‘One Belt</a>, <a href="https://publications.waset.org/abstracts/search?q=One%20Road%E2%80%99%20Initiative" title=" One Road’ Initiative"> One Road’ Initiative</a>, <a href="https://publications.waset.org/abstracts/search?q=China-Hungary%20economic%20and%20trade%20cooperation%20zone" title=" China-Hungary economic and trade cooperation zone"> China-Hungary economic and trade cooperation zone</a>, <a href="https://publications.waset.org/abstracts/search?q=function%20optimization" title=" function optimization"> function optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Central%20and%20Eastern%20Europe" title=" Central and Eastern Europe"> Central and Eastern Europe</a> </p> <a href="https://publications.waset.org/abstracts/109875/research-on-the-function-optimization-of-china-hungary-economic-and-trade-cooperation-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109875.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7216</span> The Use of Space Syntax in Urban Transportation Planning and Evaluation: Limits and Potentials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chuan%20Yang">Chuan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jing%20Bie"> Jing Bie</a>, <a href="https://publications.waset.org/abstracts/search?q=Yueh-Lung%20Lin"> Yueh-Lung Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhong%20Wang"> Zhong Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transportation planning is an academic integration discipline combining research and practice with the aim of mobility and accessibility improvements at both strategic-level policy-making and operational dimensions of practical planning. Transportation planning could build the linkage between traffic and social development goals, for instance, economic benefits and environmental sustainability. The transportation planning analysis and evaluation tend to apply empirical quantitative approaches with the guidance of the fundamental principles, such as efficiency, equity, safety, and sustainability. Space syntax theory has been applied in the spatial distribution of pedestrian movement or vehicle flow analysis, however rare has been written about its application in transportation planning. The correlated relationship between the variables of space syntax analysis and authentic observations have declared that the urban configurations have a significant effect on urban dynamics, for instance, land value, building density, traffic, crime. This research aims to explore the potentials of applying Space Syntax methodology to evaluate urban transportation planning through studying the effects of urban configuration on cities transportation performance. By literature review, this paper aims to discuss the effects that urban configuration with different degrees of integration and accessibility have on three elementary components of transportation planning - transportation efficiency, transportation safety, and economic agglomeration development - via intensifying and stabilising the nature movements generated by the street network. And then the potential and limits of Space Syntax theory to study the performance of urban transportation and transportation planning would be discussed in the paper. In practical terms, this research will help future research explore the effects of urban design on transportation performance, and identify which patterns of urban street networks would allow for most efficient and safe transportation performance with higher economic benefits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transportation%20planning" title="transportation planning">transportation planning</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20syntax" title=" space syntax"> space syntax</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20agglomeration" title=" economic agglomeration"> economic agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20efficiency" title=" transportation efficiency"> transportation efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20safety" title=" transportation safety"> transportation safety</a> </p> <a href="https://publications.waset.org/abstracts/102622/the-use-of-space-syntax-in-urban-transportation-planning-and-evaluation-limits-and-potentials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7215</span> Modeling of Polyethylene Particle Size Distribution in Fluidized Bed Reactors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Marandi">R.

The multilayer polymeric flow model (MPFM) was used to calculate the growth rate of a single polymer particle under intra-heat and mass transfer resistance. The industrial plant data were used to calculate the growth rate of polymer particle and the polymer PSD. Numerical simulations carried out to describe the influence of effective monomer diffusion coefficient, polymerization rate and initial catalyst size on the catalyst particle growth and final polymer PSD. The results present that the intra-heat and mass limitation is important for the ethylene polymerization, the growth rate of particle and the polymer PSD in the fluidized bed reactor. The effect of the agglomeration on the PSD is also considered. The result presents that the polymer particle size distribution becomes broader as the agglomeration exits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=population%20balance" title="population balance">population balance</a>, <a href="https://publications.waset.org/abstracts/search?q=olefin%20polymerization" title=" olefin polymerization"> olefin polymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed%20reactor" title=" fluidized bed reactor"> fluidized bed reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20distribution" title=" particle size distribution"> particle size distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=agglomeration" title=" agglomeration"> agglomeration</a> </p> <a href="https://publications.waset.org/abstracts/35596/modeling-of-polyethylene-particle-size-distribution-in-fluidized-bed-reactors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35596.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7214</span> Effect of Needle Diameter on the Morphological Structure of Electrospun n-Bi2O3/Epoxy-PVA Nanofiber Mats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bassam%20M.%20Abunahel">Bassam M.

Growing evidences have been highlighted that there are risks of physico-chemical properties dependent toxicity with special attention to “TiO2-NPs and human immune system”. Unfortunately, agglomeration and aggregation have frequently been ignored in immuno-toxicological studies, even though agglomeration and aggregation would be expected to affect nanotoxicity since it changes the size, shape, surface area, and other properties of the TiO2-NPs. In this present investigation, we assessed the immune toxic effect of TiO2-NPs on human immune cells Total WBC including Lymphocytes (T cells (CD3+), T helper cells (CD3+, CD4+), Suppressor/cytotoxic T cells (CD3+/CD8+) and NK cells (CD3-/CD16+ and CD56+), Monocytes (CD14+, CD3-) and B lymphocytes (CD19+, CD3-) in order to find the immunological response (IL1A, IL1B, IL2 IL-4, IL5 IL-6, IL-10, IL-12, IL-13, IFN-γ, TGF-β, and TNF-a) and redox gene regulation (TNF, p53, BCl-2, CAT, GSTA4, TNF, CYP1A, POR, SOD1, GSTM3, GPX1, and GSR1)-linking physicochemical properties with special reference to agglomeration of TiO2-NPs. Our findings suggest that TiO2-NPs altered cytokine production, enhanced phagocytic indexing, metabolic stress through specific immune regulatory- genes expression in different WBC subsets and may contribute to pro-inflammatory response. Although TiO2-NPs have great advantages in the personal care products, biomedical, food and agricultural products, its chronic and acute immune-toxicity still need to be assessed carefully with special reference to food and environmental safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TiO2%20nanoparticles" title="TiO2 nanoparticles">TiO2 nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokine" title=" cytokine"> cytokine</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20immune%20cells" title=" human immune cells"> human immune cells</a> </p> <a href="https://publications.waset.org/abstracts/13678/proinflammatory-response-of-agglomerated-tio2-nanoparticles-in-human-immune-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13678.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7211</span> Insights into Particle Dispersion, Agglomeration and Deposition in Turbulent Channel Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Afkhami">Mohammad Afkhami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hassanpour"> Ali Hassanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Fairweather"> Michael Fairweather</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work described in this paper was undertaken to gain insight into fundamental aspects of turbulent gas-particle flows with relevance to processes employed in a wide range of applications, such as oil and gas flow assurance in pipes, powder dispersion from dry powder inhalers, and particle resuspension in nuclear waste ponds, to name but a few. In particular, the influence of particle interaction and fluid phase behavior in turbulent flow on particle dispersion in a horizontal channel is investigated. The mathematical modeling technique used is based on the large eddy simulation (LES) methodology embodied in the commercial CFD code FLUENT, with flow solutions provided by this approach coupled to a second commercial code, EDEM, based on the discrete element method (DEM) which is used for the prediction of particle motion and interaction. The results generated by LES for the fluid phase have been validated against direct numerical simulations (DNS) for three different channel flows with shear Reynolds numbers, Reτ = 150, 300 and 590. Overall, the LES shows good agreement, with mean velocities and normal and shear stresses matching those of the DNS in both magnitude and position. The research work has focused on the prediction of those conditions favoring particle aggregation and deposition within turbulent flows. Simulations have been carried out to investigate the effects of particle size, density and concentration on particle agglomeration. Furthermore, particles with different surface properties have been simulated in three channel flows with different levels of flow turbulence, achieved by increasing the Reynolds number of the flow. The simulations mimic the conditions of two-phase, fluid-solid flows frequently encountered in domestic, commercial and industrial applications, for example, air conditioning and refrigeration units, heat exchangers, oil and gas suction and pressure lines. The particle size, density, surface energy and volume fractions selected are 45.6, 102 and 150 µm, 250, 1000 and 2159 kg m-3, 50, 500, and 5000 mJ m-2 and 7.84 × 10-6, 2.8 × 10-5, and 1 × 10-4, respectively; such particle properties are associated with particles found in soil, as well as metals and oxides prevalent in turbulent bounded fluid-solid flows due to erosion and corrosion of inner pipe walls. It has been found that the turbulence structure of the flow dominates the motion of the particles, creating particle-particle interactions, with most of these interactions taking place at locations close to the channel walls and in regions of high turbulence where their agglomeration is aided both by the high levels of turbulence and the high concentration of particles. A positive relationship between particle surface energy, concentration, size and density, and agglomeration was observed. Moreover, the results derived for the three Reynolds numbers considered show that the rate of agglomeration is strongly influenced for high surface energy particles by, and increases with, the intensity of the flow turbulence. In contrast, for lower surface energy particles, the rate of agglomeration diminishes with an increase in flow turbulence intensity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agglomeration" title="agglomeration">agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20flow" title=" channel flow"> channel flow</a>, <a href="https://publications.waset.org/abstracts/search?q=DEM" title=" DEM"> DEM</a>, <a href="https://publications.waset.org/abstracts/search?q=LES" title=" LES"> LES</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence" title=" turbulence "> turbulence </a> </p> <a href="https://publications.waset.org/abstracts/28803/insights-into-particle-dispersion-agglomeration-and-deposition-in-turbulent-channel-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28803.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7210</span> Study for Utilization of Industrial Solid Waste, Generated by the Discharge of Casting Sand Agglomeration with Clay, Blast Furnace Slag and Sugar Cane Bagasse Ash in Concrete Composition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Sergio%20de%20Andrade%20Zago">Mario Sergio de Andrade Zago</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Mazariegos%20Pablos"> Javier Mazariegos Pablos</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduvaldo%20Paulo%20Sichieri"> Eduvaldo Paulo Sichieri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research project accomplished a study on the technical feasibility of recycling industrial solid waste generated by the discharge of casting sand agglomeration with clay, blast furnace slag and sugar cane bagasse ash. For this, the plan proposed a methodology that initially establishes a process of solid waste encapsulation, by using solidification/stabilization technique on Portland cement matrices, in which the residuals act as small and large aggregates on the composition of concrete, and later it presents the possibility of using this concrete in the manufacture of concrete pieces (concrete blocks) for paving. The results obtained in this research achieved the objective set with great success, regarding the manufacturing of concrete pieces (blocks) for paving urban roads, whenever there is special vehicle traffic or demands capable of producing accentuated abrasion effects (surpassing the 50 MPa required by the regulation), which probes the technical practicability of using waste from sand casting agglomeration with clay and blast furnace slag used in this study, unlocking usage possibilities for construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20solid%20waste" title="industrial solid waste">industrial solid waste</a>, <a href="https://publications.waset.org/abstracts/search?q=solidification%2Fstabilization" title=" solidification/stabilization"> solidification/stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=Portland%20cement" title=" Portland cement"> Portland cement</a>, <a href="https://publications.waset.org/abstracts/search?q=reuse" title=" reuse"> reuse</a>, <a href="https://publications.waset.org/abstracts/search?q=bagasse%20ash%20in%20the%20sugar%20cane" title=" bagasse ash in the sugar cane"> bagasse ash in the sugar cane</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete "> concrete </a> </p> <a href="https://publications.waset.org/abstracts/9546/study-for-utilization-of-industrial-solid-waste-generated-by-the-discharge-of-casting-sand-agglomeration-with-clay-blast-furnace-slag-and-sugar-cane-bagasse-ash-in-concrete-composition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9546.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7209</span> Identifying and Optimizing the Critical Excipients in Moisture Activated Dry Granulation Process for Two Anti TB Drugs of Different Aqueous Solubilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Srujana">K.

Sudhakar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Isoniazide (INH) a freely water soluble and pyrazinamide (Z) a practically water insoluble first line anti tubercular (TB) drugs were identified as candidates for optimizing the Moisture Activated Dry Granulation (MADG) process. The work focuses on identifying the effect of binder type and concentration as well as the effect of magnesium stearate level on critical quality attributes of Disintegration time (DT) and in vitro dissolution test when the tablets are processed by the MADG process. Also, the level of the drug concentration, binder concentration and fluid addition during the agglomeration stage of the MADG process was evaluated and optimized. For INH, it was identified that for tablets with HPMC as binder at both 2% w/w and 5% w/w level and Magnesium stearate upto 1%w/w as lubrication the DT is within 1 minute and the dissolution rate is the fastest (> 80% in 15 minutes) as compared to when PVP or pregelatinized starch is used as binder. Regarding the process, fast disintegrating and rapidly dissolving tablets are obtained when the level of drug, binder and fluid uptake in agglomeration stage is 25% w/w 0% w/w binder and 0.033%. w/w. At the other 2 levels of these three ingredients, the DT is significantly impacted and dissolution is also slower. For pyrazinamide,it was identified that for the tablets with 2% w/w level of each of PVP as binder and Cross Caramellose Sodium disintegrant the DT is within 2 minutes and the dissolution rate is the fastest(>80 in 15 minutes)as compared to when HPMC or pregelatinized starch is used as binder. This may be attributed to the fact that PVP may be acting as a solubilizer for the practically insoluble Pyrazinamide. Regarding the process,fast dispersing and rapidly disintegrating tablets are obtained when the level of drug, binder and fluid uptake in agglomeration stage is 10% w/w,25% w/w binder and 1% w/w.At the other 2 levels of these three ingredients, the DT is significantly impacted and dissolution is comparatively slower and less complete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agglomeration%20stage" title="agglomeration stage">agglomeration stage</a>, <a href="https://publications.waset.org/abstracts/search?q=isoniazide" title=" isoniazide"> isoniazide</a>, <a href="https://publications.waset.org/abstracts/search?q=MADG" title=" MADG"> MADG</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20distribution%20stage" title=" moisture distribution stage"> moisture distribution stage</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrazinamide" title=" pyrazinamide "> pyrazinamide </a> </p> <a href="https://publications.waset.org/abstracts/8977/identifying-and-optimizing-the-critical-excipients-in-moisture-activated-dry-granulation-process-for-two-anti-tb-drugs-of-different-aqueous-solubilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8977.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7208</span> Study on the Relationship between the Urban Geography and Urban Agglomeration to the Effects of Carbon Emissions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peng-Shao%20Chen">Peng-Shao Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yen-Jong%20Chen"> Yen-Jong Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, global warming, the dramatic change in energy prices and the exhaustion of natural resources illustrated that energy-related topic cannot be ignored. Despite the relationship between the cities and CO₂ emissions has been extensively studied in recent years, little attention has been paid to differences in the geographical location of the city. However, the geographical climate has a great impact on lifestyle from city to city, such as the type of buildings, the major industry of the city, etc. Therefore, the paper instigates empirically the effects of kinds of urban factors and CO₂ emissions with consideration of the different geographic, climatic zones which cities are located. Using the regression model and a dataset of urban agglomeration in East Asia cities with over one million population, including 2005, 2010, and 2015 three years, the findings suggest that the impact of urban factors on CO₂ emissions vary with the latitude of the cities. Surprisingly, all kinds of urban factors, including the urban population, the share of GDP in service industry, per capita income, and others, have different level of impact on the cities locate in the tropical climate zone and temperate climate zone. The results of the study analyze the impact of different urban factors on CO₂ emissions in urban area with different geographical climate zones. These findings will be helpful for the formulation of relevant policies for urban planners and policy makers in different regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20emissions" title="carbon emissions">carbon emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20agglomeration" title=" urban agglomeration"> urban agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20factor" title=" urban factor"> urban factor</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20geography" title=" urban geography"> urban geography</a> </p> <a href="https://publications.waset.org/abstracts/89576/study-on-the-relationship-between-the-urban-geography-and-urban-agglomeration-to-the-effects-of-carbon-emissions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89576.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7207</span> Sociological Research as a Tool of Social Assessment of the Territory in Urban Planning: In a Case of Kazakhstan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexey%20Abilov">Alexey Abilov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sociological research in the form of a questionnaire survey of the population in the last decade has become an essential part of a comprehensive assessment of the territory in the practice of urban planning in Kazakhstan. This method was successfully used for developing master plans of settlements, urban agglomerations, and projects of detailed planning of individual sections of the urban environment. Also, it greatly contributes to the objectification of design solutions, since in addition to the traditional expert multifactorial assessment of urban development territories by professional designers, they provide an opportunity to consider existing urban development problems at the local level from the inside, through the eyes of the living population. A comparison of two areas of assessment of the territory -expert and social- allows us to give a more balanced final assessment, which can serve as a strong basis for making correct design decisions. The author of the article shows this by the example of the social assessment of the territory of the Almaty urban agglomeration in the form of a questionnaire survey of the population conducted in order to assess the quality of the living environment of the population, preferences in place and forms of recreation, as well as to delimitation the boundaries of the agglomeration. At the same time, the author's methodology of qualitative and quantitative assessment of the territory divided into polling stations is used, based on a comparison of the percentage of respondents' responses to various questionnaire questions with the total number of respondents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20assessment%20of%20territory" title="social assessment of territory">social assessment of territory</a>, <a href="https://publications.waset.org/abstracts/search?q=comprehensive%20assessment" title=" comprehensive assessment"> comprehensive assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20agglomeration" title=" urban agglomeration"> urban agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=correct%20design%20decisions" title=" correct design decisions"> correct design decisions</a> </p> <a href="https://publications.waset.org/abstracts/174580/sociological-research-as-a-tool-of-social-assessment-of-the-territory-in-urban-planning-in-a-case-of-kazakhstan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7206</span> An Attempt at the Multi-Criterion Classification of Small Towns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jerzy%20Banski">Jerzy Banski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The basic aim of this study is to discuss and assess different classifications and research approaches to small towns that take their social and economic functions into account, as well as relations with surrounding areas. The subject literature typically includes three types of approaches to the classification of small towns: 1) the structural, 2) the location-related, and 3) the mixed. The structural approach allows for the grouping of towns from the point of view of the social, cultural and economic functions they discharge. The location-related approach draws on the idea of there being a continuum between the center and the periphery. A mixed classification making simultaneous use of the different approaches to research brings the most information to bear in regard to categories of the urban locality. Bearing in mind the approaches to classification, it is possible to propose a synthetic method for classifying small towns that takes account of economic structure, location and the relationship between the towns and their surroundings. In the case of economic structure, the small centers may be divided into two basic groups – those featuring a multi-branch structure and those that are specialized economically. A second element of the classification reflects the locations of urban centers. Two basic types can be identified – the small town within the range of impact of a large agglomeration, or else the town outside such areas, which is to say located peripherally. The third component of the classification arises out of small towns’ relations with their surroundings. In consequence, it is possible to indicate 8 types of small-town: from local centers enjoying good accessibility and a multi-branch economic structure to peripheral supra-local centers characterised by a specialized economic structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20towns" title="small towns">small towns</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20structure" title=" functional structure"> functional structure</a>, <a href="https://publications.waset.org/abstracts/search?q=localization" title=" localization"> localization</a> </p> <a href="https://publications.waset.org/abstracts/132686/an-attempt-at-the-multi-criterion-classification-of-small-towns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132686.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7205</span> The Effects of Cultural Distance and Institutions on Foreign Direct Investment Choices: Evidence from Turkey and China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihal%20Kartaltepe%20Behram">Nihal Kartaltepe Behram</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6ksel%20Ataman"> Göksel Ataman</a>, <a href="https://publications.waset.org/abstracts/search?q=Dila%20Ok%C3%A7u"> Dila Okçu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the development of foreign direct investments, the social, cultural, political and economic interactions between countries and institutions have become visible and they have become determining factors for the strategic structuring and market goals. In this context the purpose of this study is to investigate the effects of cultural distance and institutions on foreign direct investment choices in terms of location and investment model. For international establishments, the concept of culture, as well as the concept of cultural distance, is taken specifically into consideration, especially in the selection of methods for entering the market. In the researches and empirical studies conducted, a direct relationship between cultural distance and foreign direct investments is set and institutions and effective variable factors are examined at the level of defining the investment types. When the detailed calculation strategies and empirical researches and studies are taken into consideration, the most common methods for determining the direct investment model, considering the cultural distances, are full-ownership enterprises and joint ventures. Also, when all of the factors affecting the investments are taken into consideration, it was seen that the effect of institutions such as Government Intervention, Intellectual Property Rights, Corruption and Contract Enforcements is very important. Furthermore agglomeration is more intense and effective on the investment, compared to other factors. China has been selected as the target country, due to its effectiveness in world economy and its contributions to developing countries, which has commercial relationships with. Qualitative research methods are used for this study conducted, to measure the effects of determinative variable factors in the hypotheses of study, on the direct foreign investors and to evaluate the findings. In this study in-depth interview is used as a data collection method and the data analysis is made through descriptive analysis. Foreign Direct Investments are so reactive to institutions and cultural distance is identified by all interviews and analysis. On the other hand, agglomeration is the most strong determiner factor on foreign direct investors in Chinese Market. The reason of this factors, which comprise the sectorial aggregate, are not the strongest factors as agglomeration that the most important finding. We expect that this study became a beneficial guideline for developed and developing countries and local and national institutions’ strategic plans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China" title="China">China</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20distance" title=" cultural distance"> cultural distance</a>, <a href="https://publications.waset.org/abstracts/search?q=Foreign%20Direct%20Investments" title=" Foreign Direct Investments"> Foreign Direct Investments</a>, <a href="https://publications.waset.org/abstracts/search?q=institutions" title=" institutions"> institutions</a> </p> <a href="https://publications.waset.org/abstracts/23597/the-effects-of-cultural-distance-and-institutions-on-foreign-direct-investment-choices-evidence-from-turkey-and-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7204</span> Analysis of the Decoupling Relationship between Urban Green Development and the Level of Regional Integration Based on the Tapio Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruoyu%20Mao">Ruoyu Mao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exploring the relationship between urban green development and regional integration level is of great significance for realising regional high quality and sustainable development.

According to the last estimation of economic progress of European countries, this recovery is not strong enough. Among others, it will depend on economic policy, where and in which way, the economic indicators will proceed. Economic theories postulate that the economic subjects prefer stably, continual economic policy without repeated and strong fluctuations. This policy is perceived as support of economic growth. Mostly in crises period, when the government must cope with consequences of recession, the economic policy becomes unpredictable for many subjects and economic policy uncertainty grows, which have negative influence on economic growth. The aim of this paper is to use panel regression to prove or disprove this hypothesis on the example of five largest European economies in the period 2008–2012. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20crises%20in%20Europe" title="economic crises in Europe">economic crises in Europe</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20policy" title=" economic policy"> economic policy</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=panel%20analysis%20regression" title=" panel analysis regression"> panel analysis regression</a> </p> <a href="https://publications.waset.org/abstracts/8675/how-do-crisis-affect-economic-policy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8675.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">387</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7202</span> Influence of Hygro-Thermo-Mechanical Loading on Buckling and Vibrational Behavior of FG-CNT Composite Beam with Temperature Dependent Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Kumar">Puneet Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonnalagadda%20Srinivas"> Jonnalagadda Srinivas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The authors report here vibration and buckling analysis of functionally graded carbon nanotube-polymer composite (FG-CNTPC) beams under hygro-thermo-mechanical environments using higher order shear deformation theory. The material properties of CNT and polymer matrix are often affected by temperature and moisture content. A micromechanical model with agglomeration effect is employed to compute the elastic, thermal and moisture properties of the composite beam. The governing differential equation of FG-CNTRPC beam is developed using higher-order shear deformation theory to account shear deformation effects. The elastic, thermal and hygroscopic strain terms are derived from variational principles. Moreover, thermal and hygroscopic loads are determined by considering uniform, linear and sinusoidal variation of temperature and moisture content through the thickness. Differential equations of motion are formulated as an eigenvalue problem using appropriate displacement fields and solved by using finite element modeling. The obtained results of natural frequencies and critical buckling loads show a good agreement with published data. The numerical illustrations elaborate the dynamic as well as buckling behavior under uniaxial load for different environmental conditions, boundary conditions and volume fraction distribution profile, beam slenderness ratio. Further, comparisons are shown at different boundary conditions, temperatures, degree of moisture content, volume fraction as well as agglomeration of CNTs, slenderness ratio of beam for different shear deformation theories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hygrothermal%20effect" title="hygrothermal effect">hygrothermal effect</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling%20load" title=" buckling load"> buckling load</a>, <a href="https://publications.waset.org/abstracts/search?q=agglomeration" title=" agglomeration"> agglomeration</a> </p> <a href="https://publications.waset.org/abstracts/56592/influence-of-hygro-thermo-mechanical-loading-on-buckling-and-vibrational-behavior-of-fg-cnt-composite-beam-with-temperature-dependent-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56592.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7201</span> Convergence or Divergence of Economic Growth within the ASEAN Community: Challenges for the AEC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Gugler">Philippe Gugler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This contribution reflects some important questions regarding inter alia the economic development occurring in the light of the ASEAN’s goal of creating the ASEAN Economic Community (AEC) by 2015.

Using ecosystem services theory, The study explore the relationship between land use in the Beijing-Tianjin-Hebei (B-T-H) region and the Food-Water-Energy (F-W-E) nexus from 2000 to 2030. We assess ecosystem services using the InVEST: Habitat Quality (HQ), Water Yield (WY), Carbon Sequestration (CS), Soil Retention (SDR), and Food Production (FP). The study find an annual expansion of construction land alongside a significant decline in cultivated land. Additionally, HQ, CS, and per capita FP decline annually until 2020 and are expected to persist through 2030. In contrast, WY and SDR grow annually but may decline by 2030. Spearman coefficient analysis reveals synergies between HQ and CS, SDR and CS, and SDR and HQ, with trade-offs between CS and WY and HQ and WY. Utilizing the K-means clustering analysis method, we introduce county-based spatial planning for the F-W-E system, offering valuable insights and recommendations for sustainable resource management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food-water-energy%20%28F-W-E%29" title="food-water-energy (F-W-E)">food-water-energy (F-W-E)</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20services" title=" ecosystem services"> ecosystem services</a>, <a href="https://publications.waset.org/abstracts/search?q=trade-offs%20and%20synergies" title=" trade-offs and synergies"> trade-offs and synergies</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20service%20bundle" title=" ecosystem service bundle"> ecosystem service bundle</a>, <a href="https://publications.waset.org/abstracts/search?q=county-based" title=" county-based"> county-based</a> </p> <a href="https://publications.waset.org/abstracts/176083/urbanization-effects-on-the-food-water-energy-nexus-within-ecosystem-services-a-case-study-of-the-beijing-tianjin-hebei-urban-agglomeration-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7199</span> Elastic Behaviour of Graphene Nanoplatelets Reinforced Epoxy Resin Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20K.%20Srivastava">V. K. Srivastava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Graphene has recently attracted an increasing attention in nanocomposites applications because it has 200 times greater strength than steel, making it the strongest material ever tested. Graphene, as the fundamental two-dimensional (2D) carbon structure with exceptionally high crystal and electronic quality, has emerged as a rapidly rising star in the field of material science. Graphene, as defined, as a 2D crystal, is composed of monolayers of carbon atoms arranged in a honeycombed network with six-membered rings, which is the interest of both theoretical and experimental researchers worldwide. The name comes from graphite and alkene. Graphite itself consists of many graphite-sheets stacked together by weak van der Waals forces. This is attributed to the monolayer of carbon atoms densely packed into honeycomb structure. Due to superior inherent properties of graphene nanoplatelets (GnP) over other nanofillers, GnP particles were added in epoxy resin with the variation of weight percentage. It is indicated that the DMA results of storage modulus, loss modulus and tan δ, defined as the ratio of elastic modulus and imaginary (loss) modulus versus temperature were affected with addition of GnP in the epoxy resin. In epoxy resin, damping (tan δ) is usually caused by movement of the molecular chain. The tan δ of the graphene nanoplatelets/epoxy resin composite is much lower than that of epoxy resin alone. This finding suggests that addition of graphene nanoplatelets effectively impedes movement of the molecular chain. The decrease in storage modulus can be interpreted by an increasing susceptibility to agglomeration, leading to less energy dissipation in the system under viscoelastic deformation. The results indicates the tan δ increased with the increase of temperature, which confirms that tan δ is associated with magnetic field strength. Also, the results show that the nanohardness increases with increase of elastic modulus marginally. GnP filled epoxy resin gives higher value than the epoxy resin, because GnP improves the mechanical properties of epoxy resin. Debonding of GnP is clearly observed in the micrograph having agglomeration of fillers and inhomogeneous distribution. Therefore, DMA and nanohardness studies indiacte that the elastic modulus of epoxy resin is increased with the addition of GnP fillers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agglomeration" title="agglomeration">agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20modulus" title=" elastic modulus"> elastic modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resin" title=" epoxy resin"> epoxy resin</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20nanoplatelet" title=" graphene nanoplatelet"> graphene nanoplatelet</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20modulus" title=" loss modulus"> loss modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=nanohardness" title=" nanohardness"> nanohardness</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20modulus" title=" storage modulus"> storage modulus</a> </p> <a href="https://publications.waset.org/abstracts/36868/elastic-behaviour-of-graphene-nanoplatelets-reinforced-epoxy-resin-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36868.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7198</span> Explore Urban Spatial Density with Boltzmann Statistical Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianjia%20Wang">Jianjia Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong%20Yu"> Tong Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Haoran%20Zhu"> Haoran Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun%20Liu"> Kun Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinwei%20Hao"> Jinwei Hao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The underlying pattern in the modern city is agglomeration. To some degree, the distribution of urban spatial density can be used to describe the status of this assemblage. There are three intrinsic characteristics to measure urban spatial density, namely, Floor Area Ratio (FAR), Building Coverage Ratio (BCR), and Average Storeys (AS). But the underlying mechanism that contributes to these quantities is still vague in the statistical urban study. In this paper, we explore the corresponding extrinsic factors related to spatial density. These factors can further provide the potential influence on the intrinsic quantities. Here, we take Shanghai Inner Ring Area and Manhattan in New York as examples to analyse the potential impacts on urban spatial density with six selected extrinsic elements. Ebery single factor presents the correlation to the spatial distribution, but the overall global impact of all is still implicit. To handle this issue, we attempt to develop the Boltzmann statistical model to explicitly explain the mechanism behind that. We derive a corresponding novel quantity, called capacity, to measure the global effects of all other extrinsic factors to the three intrinsic characteristics. The distribution of capacity presents a similar pattern to real measurements. This reveals the nonlinear influence on the multi-factor relations to the urban spatial density in agglomeration. <p class="card-text"><strong>Keywords:</strong> <a
