Abstract: We present an analysis of the vertical wavenumber and frequency spectra of atmospheric motions in the lower stratosphere observed using the Poker Flat, Alaska MST radar during a 5-day period in February 1986. Our purposes ...

Abstract: Right turn plus U-turn at median openings as an alternative to direct left turn has been considered important issue in access management. The motivation behind using this strategy comes from the consideration of safety as ...

Abstract: A component dowel-bar model has been developed to simulate the doweled joint in portland-cement-concrete (PCC) pavements. The model consists of two bending beams of finite length, embedded in concrete, connected by a ...

Abstract: Two attitude coordination controllers that make the system converge to the equilibrium point in finite time are designed for spacecraft formation flying with actuator saturation constraints. The first finite-time attitude ...
