We thank Jackson Brill,Ross Wilkinson,Kyle Sterns,and James Tripp Hurt for help with recruiting and testing and Alena Grabowski for loaning us her Parvo system while ours was on the fritz.The running shoes used for this study were provided by Nike.
Background:Compared to conventional racing shoes,Nike Vaporfly 4% running shoes reduce the metabolic cost of level treadmill running by4%.The reduction is attributed to their lightweight,highly compliant,and resilient...

Based on in-mine instrumentation and theoretical analysis of the unsymmetrical large-deformation that occurred in the roadway after excavation,Differential Floor Heave(DFH)was found to be the main reason for roadway f...
This study presents a methodology for analysis of the industrial machine alignment in the production line. The level of land subsidence in the area of the industrial machine location was assessed by adopting Hall Effe...
Most hovering insects flap their wings in a horizontal plane, called 'normal hovering'. But some of the best hoverers, e.g. true hoverflies, hover with an inclined stroke plane. In the present paper, the longitudina...
Intense solar radiation is one of the key design problems for buildings in tropical regions.The recommended practice is to install shading devices,particularly to protect glazing systems.However,many design factors do...
