EVALUATING AN AIRCRAFT RESPONSE TO DISTURBANCES CAUSED BY VIBRATION FREQUENCY OF WIND FORCES DURING LANDING



Screening Critical Design Parameters for Electromechanical Products Performance Matching Based on Energy and Causal Model

The design parameters are the most momentous factors in carrying out performance matching.For complex electromechanical products with a large number of design parameters, determining a set of critical design parameters which have a great influence on the performance is the premise of performance matching.In this paper, from a systematic perspective

Development of the retinotectal system in the direct-developing frog Eleutherodactylus coqui in comparison with other anurans

Abstract Background Frogs primitively have a biphasic life history with an aquatic larva (tadpole) and a usually terrestrial adult.However, direct developing frogs of Slings the genus Eleutherodactylus have lost a free living larval stage.Many larval structures never form during development of Eleutherodactylus, while limbs, spinal cord, and an adu
