In the intelligent transportation field, object recognition, detection, and location applications face significant real-time challenges. To address these issues, we propose an automatic sensor-based data loading unloading optimization strategy for algorithm models. This is designed artificial intelligence (AI) application systems that leverage edge computing. It aims to solve resource allocation improve operational efficiency in computing environments. By doing so, it meets requirements of...

China's urban development is transitioning from an extensive expansion model to intensive improvement approach. Promoting renewal through stock land resources has become a key focus in contemporary spatial governance. As cities enter the era, accurately identifying quantity and distribution of inefficient crucial for improving use efficiency. However, existing identification methods space face challenges including limited data sources, over-reliance on expert experience insufficient...

Empirical studies of urban expansion have increased rapidly in recent decades worldwide. Previous mainly focused on cities China, the United States or African countries, with Brazilian receiving less attention. Moreover, such are rare purpose-built cities. Taking from scratch (1960) to agglomeration (2015) Federal District Brazil (FDB) as an example, this study aims quantify magnitude, patterns, modes, types and efficiency land attempts reveal some implications within sustainable thinking....

If urban sprawl is to be avoided in China the next ten years, it not only crucial understand overall history, current status, and future trends of expansion there, but also these differences, this presently lacking. In study, remotely sensed images with approximately 30 m spatial resolution were used quantitatively assess temporal patterns 60 Chinese cities (1973–2013). Urban-expansion-process curves studied drawn using annual area as an indicator. Curve similarity analysis generated four...

China’s transportation industry has made great achievements in the past 40 years of reform and opening up. At same time, it gradually accumulated a series problems. These problems have led to closer more complex social economic connection within between regions different scales. The existing research only carries out characteristic analysis urban network spatial pattern from single perspective such as “flow space” theory, interaction model accessibility method, fails accurately describe...

China has been through a period of remarkable urban sprawl since the reform and opening-up policy in 1978, with highest urbanization occurring coastal zones. Sustainable development requires better understanding spatiotemporal characteristics urbanization. This study systematically explored Chinese cities visual interpretation method from 1979 to 2013. The results show that built-up areas kept increasing at faster pace during (i.e., increased about 9-fold 34 years), especially first decade...

As complex systems, the spatial structure of urban systems can be analyzed by entropy theory. This paper first calculates interaction force between cities based on gravity model, relationship matrix is constructed using method network modeling, and modeling system calculated. Secondly, Efficiency Entropy (EE), Quality (QE), System (SE) are calculated information entropy. Finally, taking Huaihe River Basin (HRB) as a case study, model verification empirical analysis performed. It found that...

Increasing demand for food and bioenergy has altered the global landscape dramatically in recent years. Land use land cover change affects environmental system many ways through biophysical biogeochemical mechanisms. In this study, we evaluate impacts of driven by crop expansion conversion on water budget, carbon exchange, storage Midwest USA. A dynamic vegetation model was used to simulate examine a historical case based distribution data from United States Department Agriculture National...

Evaluation of the railway network distribution and its impacts on social economic development has great significance for building an efficient comprehensive system. To address lack evaluation indicators to assess pattern at macro scale, this study selects eight indicators—railway density, proximity, shortest travel time, train frequency, population, Gross Domestic Product (GDP), gross industrial value above designated size, fixed asset investment—as basis integrated index which is used...

With the rapid development of Information and Communications Technology (ICT) transportation infrastructure, flows people between cities have become cornerstone shaping regional integration. Although research studies about movement aroused widespread interest in academia, temporal spatial dynamics daily mobility is sparse, which called heterogeneity cities. This aims to study changes (Heterogeneity) population cities, using big data obtained through China Unicom, terms mapping network...

Digital economy is a new factor to promote regional development. To explore the impact of digital on level marine economic growth, we establish panel threshold model with capital for as variable and growth explained based neoclassical theory data regions in China during 2006 2016. We performed regression analysis understand economy’s influence growth. The results show that has double effect. When investment low, influences negatively. reaches medium level, enhances significantly. However, if...

Land use and land cover change has become an important trend in research on global environmental change, especially developing countries. For instance, Chinese coastal zone witnessed remarkable changes since the reform opening up policy launched 1978. In order to explore China, paper utilized a transition matrix rates of land-use metrics discuss temporal-spatial patterns from 1980's 2010. The results clearly demonstrated that structure spatial distribution have been significantly changed;...
