The Amazon drainage basin (Amazonia) contains the largest continuous area of tropical rainforest in the world and is the most species-rich terrestrial ecosystem on Earth.In biogeographical terms, the Amazon rainforest Wooden Houses is still somewhat of a mystery, beset by data shortfalls in many taxonomic groups, lacking systematic surveys and face
This study explores the deformation characteristics of surrounding rock during tunnel construction through fault fracture zones.A numerical model is established using ABAQUS to analyze the interaction between the shield machine, support system, and geotechnical materials.The model incorporates key factors, including palm face support force, groutin
Autonomous systems are these systems which power themselves from the available ambient energies in addition to their duties.In the next few years, autonomous systems will pervade society and they will find their ways into different applications related to health, security, comfort and entertainment.Piezoelectric harvesters are possible energy conve
Due to the uncontrollable weather conditions, it is difficult to carry out the controllable prototype test to study fatigue damage of transmission tower and armour clamp and the effect evaluation of antigalloping device under actual transmission line galloping.Considering the geometric nonlinearity of Eyeliner the transmission line system, this stu
The properties of brushless DC motor (BLDCM) are similar to the fractional, slot-concentrated winding of permanent-magnet synchronous machines, Tolerance Ring and they fit well for electric vehicle application.However, BLDCM still suffers from the high commutation torque ripple in the case of the traditional square-wave current control (SWC) method
