A contact stress capacity model for cylindrical wormsets [PDF]
FME Transactions, 2022 A contact stress capacity expression is derived for cylindrical worm sets by considering the worm as a helical rack mating with a helical gear. The concept of the equivalent spur gear for a helical gear defined by the instantaneous radius of curvature in

Why Do Pit-Hours Outlive the Pit? [PDF]
SSRN Electronic Journal, 2015 We study why a majority of trades still happen during the pit hours, i.e. when the trading pit is open, even after the pit ceased to be a liquid and informative venue. We investigate the case of 30-year U.S. Treasury futures using a ten-years-long intraday data set which contains the introduction of the CME Globex platform as an example of ...
