The development of specialized agricultural villages (DSAVs) is essential for rural revitalization. However, most current studies focus on the formation (SAVs), while interpretation DSAVs from perspective geographical factors still missing. In this study, we firstly employed kernel density estimation to analyze spatial pattern and then utilized Geographic Detectors explore which factor(s) affec...

Bio-inspired legged robots have the potential to traverse uneven terrains in a very efficient way. The effectiveness of robot gait depends on joint symmetry robot; variations symmetries can result different types gaits suitable for scenarios. In literature, symmetric and asymmetric been synthesized robots; however, no relation between has studied. this research work, effect is To test suggested...

A static and a dynamic analysis model are separately established using ABAQUS finite element program to study the mechanical properties of track structure and running stability and safety of the vehicle under the condition that uneven settlement of bridge piers exists. The static model is aimed at studying the effects caused by uneven settlement alone and the dynamic one is for the effects indu...

When the power chassis of general forest machinery is working on uneven terrains, insufficient due to poor traction between wheels and road surface, which affects driving operation entire vehicle. According principle multiple-degree-of-freedom profiling, a novel articulated for forestry was designed. The innovative structure realizes active pitching, deflection, passive torsion in front rear fr...

In high-speed railway (HSR) communication systems, distributed antenna is usually employed to support frequent handover and enhance the signal to noise ratio to user equipments. In this case, dynamic time-domain power allocation and antenna selection (PAWAS) could be jointly optimized to improve the system performances. This paper consider this problem in such a simple way where dynamic switchi...

The advancement of mechatronic devices and computer science has provided an impulse to fast-moving robotic technology in last decades. Taking the category of robots as an example, besides the industrial robots for manufacturing, the list of emerging robots for spaceflight, navigation, medical nursing, service, military purposes and so on, are growing (Yang et al., 2007). Further, there are many...

The process of creating terrain and landscape models is important in a variety of computer graphics and visualization applications, from films and computer games, via flight simulators and landscape planning, to scientific visualization and subsurface modelling. Interestingly, the modelling techniques used in this large range of application areas have started to meet in the last years. In this ...

We discuss the problem of computing shortest an-isotropic paths on terrains. Anisotropic path costs take into account the length of the path traveled, possibly weighted, and the direction of travel along the faces of the terrain. Considering faces to be weighted has added realism to the study of (pure) Euclidean shortest paths. Parameters such as the varied nature of the terrain, friction, or s...
