ObjectivesThe bending-torsional coupling deformation degree of a composite propeller reflects the stiffness characteristics of the blade, which in turn have a certain correlation with its hydrodynamic performance.A fiber layer design for a composite propeller is optimized from the perspective of stiffness.MethodsTaking a DTMB 4383 composite propell
ABSTRACT Objectives Our organization links data from health care organizations and health ministries across copyright to create new knowledge.The new knowledge supports system and policy-decision makers in answering questions about the health or healthcare of population groups or healthcare sectors.This presentation provides an overview of recent a
Chinese high-speed railway has implemented large-scale network operation with an urgent need for capacity improvement.The concept of virtual coupling seems to be a promising solution that provides a new operational scenario for high-speed railway, where trains are formed into a cooperative convoy and run synchronously with small train headways.The
