We describe two diagnostic methods for measuring the velocity of mildly relativistic, high current electron beams. The first involves a measurement of the radial electrostatic potential and of the beam current and yields the time resolved, spatially averaged axial beam velocity v,,. The second requires a measurement of the beam cyclotron wavelength in the guiding magnetic field and yields the p...

Tumor therapy with light ion beams like Carbon out of a synchrotron is a topical accelerator application. In all designs the layout of the injector linac is an important factor with respect to construction and operation costs as well as to the operation performance of such a medical facility. Two alternative linac approaches which keep the number of components and setting parameters as low as p...

it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...

Reflections on changes in defining testamentary capacity Old age psychiatrists are often called upon to give expert evidence in challenges of testamentary capacity. The nineteenth-century English case, Banks v. Goodfellow (1870) remains the hallmark case for defining the criteria for testamentary capacity in Australia and other Common Law countries. However, a need to go beyond the traditional ...

We calculate the self-energies and the spectral densities of longitudinal and transverse gluons at zero temperature in color-superconducting quark matter in the color-flavor-locked (CFL) phase. We find a collective excitation, a plasmon, at energies smaller than two times the gap parameter and momenta smaller than about eight times the gap. The dispersion relation of this mode exhibits a minimu...

In the case of problematic soils and tall buildings where the design requirements cannot be satisfied merely by a raft foundation, it is of common practice to improve the raft performance by adding a number of piles so that the ultimate load capacity and settlement behavior can be enhanced. In this study, the effect of spatial variability of soil parameters on the bearing capacity of piled raft...

Buckling analysis of a functionally graded (FG) nanobeam resting on two-parameter elastic foundation is presented based on third-order shear deformation beam theory (TOSDBT). The in-plane displacement of TOSDBT has parabolic variation through the beam thickness. Also, TOSDBT accounts for shear deformation effect and verifies stress-free boundary conditions on upper and lower faces of FG nanobea...
