Explanation of the excessive deflections of the Koror-Babeldaob (KB) Bridge in Palau is presented. This bridge was built in 1977 by the cantilever method and collapsed 3 months after remedial prestressing in 1996. It was a segmental prestressed concrete girder having the worldrecord span of 241 m (790 ft.) and maximum girder depth of 14.17 m (46.5 ft). The final mid-span deflection was in desig...

A bstract We employ the “KMOC” formalism of [1] to compute classical momentum deflections spinning bodies with arbitrary spin orientations up next-to-leading order (one loop). do this in electrodynamics and gravity. The final result, valid for generic masses, is true all spins at tree level second (fourth) electromagnetic (gravity) case one loop. Furthermore, emphasis given probe limit scenario...

Toward the general goal ofpreventing ankle injuries in snowboarding accidents, the E. Wang objective of this project to develop a dynamic system model of a snowboarder and Assistant Professor, assess which model parameters, particularly those attributed to the boot, most Department of Mechanical Engineering, strongly influenced ankle deflections during a forward fall. To satisfy this objective,...

A full-field digital gradient sensing method is proposed for measuring small angular deflections of light rays due to local stresses in transparent planar solids. The working principle of the method is explained, and the governing equations are derived. The analysis shows that angular deflections of light rays can be linked to nonuniform changes in thickness and refractive index of the material...

The tactile sensations mediated by the whisker-trigeminal system allow rodents to efficiently detect and discriminate objects. These capabilities rely strongly on the temporal and spatial structure of whisker deflections. Subthreshold but also spiking receptive fields in the barrel cortex encompass a large number of vibrissae, and it seems likely that the functional properties of these multiwhi...

Literature on modern racism identifies denial as one of its key features. This article examines the discourses of denial that feature in the talk of local anti-racism actors in Australia, and asks what drives these discourses. The research draws on qualitative interviews undertaken with participants involved in local anti-racism in two case study areas, one in South Australia and the other in N...

Here we give two examples of low-latitude plasma blobs accompanied by linearly polarized perpendicular magnetic deflections which imply that associated field-aligned currents (FACs) have a 2-D sheet structure located at the blob walls. The estimated FAC density is of the order of 0.1 μA/m2. The direction of magnetic deflections points westward of the magnetic meridian and there is a linear corr...

Many micro-organisms swim through gels and non-Newtonian fluids in their natural environments. In this paper, we focus on micro-organisms which use flagella for propulsion. We address how swimming velocities are affected in nonlinearly viscoelastic fluids by examining the problem of an infinitely long cylinder with arbitrary beating motion in the Oldroyd-B fluid. We solve for the swimming veloc...
