Abstract: The triangle inequality concept is utilized in formulating the mobility conditions for a planar four-bar linkage. These conditions are used to investigate crank existence and mobility region for ...

Abstract: Slope instability caused by earthquakes often brings huge casualties and property losses, and so it has great practical significance for seismic design and disaster prevention to evaluate the stability of slopes accurately ...

Abstract: Accurate risk forecasting of agricultural water shortages has important implications for the prevention and reduction of disasters in regional agricultural production. Encountering effective precipitation (Pe) and crop ...

Abstract: The daily trips of urban residents in different transport modes reflect the urban mobility pattern and the latent spatial structure of the city, which is seldom addressed in the literature. A network-based cluster model ...

Abstract: In 1950, Wu [1] suggested that the three-dimensional inverse (design) problem of turbomachine flow may be solved approximately by a Taylor series expansion in the circumferential direction based ...

Abstract: The impact forces of submarine landslides (i.e., non-Newtonian fluids) on oil and gas pipelines, especially the most dangerous drag force, are of great significance in the design of deep-water pipelines. The drag force is ...

Abstract: The horizontal alignment of existing railway must be re-created and calibrated periodically to meet the requirements of safety, stability and comfort. Most existing re-creation methods perform local section optimization, ...
