Periods of dramatically accelerated motion, in which the flow velocity increases suddenly from about 55 cm/d to a peak of 1 00-300 cm/d and then decreases gradually over the course of a day, occurred repeatedly during June and July 1 978-8 1 in Variegated Glacier (Alaska), a surging-type glacier that surged in 1 982-83. These "mini-surges" appear to be related mechanistically to the main surge....

Specific problems of storm surge modeling in the polar seas are analyzed. The vertically integrated equations of motion and continuity are applied to the prediction of the storm surge wave in both the ice-free and ice-covered seas. The interactions of atmosphere, ice, and water are expressed by the normal and tangential stresses. A numerical grid is set over the Chukchi and Beaufort seas, and t...

New air–water flow experiments were conducted in the leading edge of dam break waves. The data highlighted the chaotic nature of the surge and provided new insights in the distributions of void fraction, velocity and air/water chord sizes. The results demonstrated a highly aerated surge front with a developing turbulent boundary layer.At the leading edge, observed mean air contents exceeded 40 ...

Gulf surges are transient disturbances that propagate along the Gulf of California (GoC) from south to north, transporting cool moist air toward the deserts of northwest Mexico and the southwest United States during the North American monsoon. They have been shown to modulate precipitation and have been linked to severe weather and flooding in northern Mexico and the southwest United States. Th...

there are many occasions where the base of a robotic manipulator is attached to a moving platform, such as on a moving ship, terrain or space shuttle. in this paper a dynamic model of a robotic manipulator mounted on a moving base is derived using both newton-euler and lagrange-euler methods. the presented models are simulated for a mitsubishi pa10-6ce robotic manipulator characteristics mounte...

The aerodynamic performance of the floating offshore wind turbine (FOWT) is obviously affected by motion platform, and becomes much more complicated considering effect tower shadow. In view this, this paper aims at investigating with without a under three most influential motions (surge, pitch yaw) computational fluid dynamic (CFD). results show that power reduced 1.58% to 2.47% due shadow moti...

Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...

conclusions in this study, some characteristics that had a positive impact on the success of a manager in a hospital surge situation were identified. these characteristics ought to be taken into account when appointing hospital administrators and designing training programs for hospital administrators with the aim of being better prepared to face disasters. background hospital administrators pl...

Floating systems provide an opportunity to expand the available tidal stream energy resource and reduce levelised cost of by increasing number viable deployment sites; simplifying installation, maintenance decommissioning; accessing greater flow speeds near free surface. However, inevitable exposure surface conditions raises questions over both power delivery survivability these systems, due pr...
