Three-Dimensional MHD Wave Propagation and Conversion to Alfvén Waves near the Solar Surface. I. Direct Numerical Solution

Abstract: The efficacy of fast – slow MHD mode conversion in the surface layers of sunspots has been demonstrated over recent years using a number of modelling techniques, including ray theory, perturbation theory, differential eigensystem analysis, and direct numerical simulation. These show that significant energy may be transferred between the fast and slow modes in the neighbourhood of the equipartition layer where the Alfven and sound speeds coincide. However, most of the models so far have been two dimensional. In three dimensions the Alfven wave may couple to the magnetoacoustic waves with important implications for energy loss from helioseismic modes and for oscillations in the atmosphere above the spot. In this paper, we carry out a numerical “scattering experiment,” placing an acoustic driver 4 Mm below the solar surface and monitoring the acoustic and Alfvenic wave energy flux high in an isothermal atmosphere placed above it. These calculations indeed show that energy conversion to upward travelling Alfven waves can be substantial, in many cases exceeding loss to slow (acoustic) waves. Typically, at penumbral magnetic field strengths, the strongest Alfven fluxes are produced when the field is inclined 30° – 40° from the vertical, with the vertical plane of wave propagation offset from the vertical plane containing field lines by some 60° – 80°.

Development of a wall-climbing robot using a tracked wheel mechanism

Abstract: In this paper, a new concept of a wall-climbing robot able to climb a vertical plane is presented. A continuous locomotive motion with a high climbing speed of 15m/min is realized by adopting a series chain on two tracked wheels on which 24 suction pads are installed. While each tracked wheel rotates, the suction pads which attach to the vertical plane are activated in sequence by specially designed mechanical valves. The engineering analysis and detailed mechanism design of the tracked wheel, including mechanical valves and the overall features, are described in this paper. It is a self-contained robot in which a vacuum pump and a power supply are integrated and is controlled remotely. The climbing performance, using the proposed mechanism, is evaluated on a vertical steel plate. Finally, the procedures are presented for an optimization experiment using Taguchi methodology to maximize vacuum pressure which is a critical factor for suction force.

Anticrab cavities for the removal of spurious vertical bunch rotations caused by crab cavities

Abstract: Many particle accelerators are proposing the use of crab cavities to correct for accelerator crossing angles or for the production of short bunches in light sources. These cavities produce a rotation to the bunch in a well-defined polarization plane. If the plane of the rotation does not align with the horizontal axis of the accelerator, the bunch will receive a small amount of spurious vertical bunch rotation. For accelerators with small vertical beam sizes and large beam-beam effects, this can cause significant unwanted effects. In this paper we propose the use of a 2nd smaller crab cavity in the vertical plane in order to cancel this effect and investigate its use in numerical simulations

Adjustable pipe coupling assembly

Abstract: An adjustable pipe coupling assembly (10) has a first clamp (30), a second clamp (32), and means (38, 40, 44) for rotating the clamps independently about a first common axis shared by the clamps and extending vertically. The first clamp (30) includes a first pair of opposed ears (52, 54) spaced apart so as to allow a first pipe (16) to be located therebetween. Each one of the opposed ears (52, 54) has a hole (56, 58) formed therethrough. The pair of holes (56, 58) share a second common axis extending in a first horizontal plane and are adapted to receive first pivot means, such as a bolt (60), therethrough for engaging the first pipe (16). The first pipe (16) is, as a result, pivotable in a first vertical plane about the second common axis. The second clamp (32) includes a second pair of opposed ears (52, 54) spaced apart so as to allow a second pipe (18) to be located therebetween. Each one of the opposed ears has a hole (56, 58) formed threthrough. The pair of holes share a third common axis perpendicular to the second common axis and extending in a second horizontal plane, the pair of holes being adapted to receive second pivot means, such as a bolt (60), therethrough for engaging the second pipe (18). The second pipe (18) is, as a result, pivotable in a second vertical plane about the third common axis. The arrangement is such that, in use, the rotating means rotate the clamps so as to adjust the horizontal angle between the second and third common axes, and each of the first and second pivot means pivot their respective pipe so as to adjust the vertical angle between the first and second pipes.

Vertical structure of the quasi-two-dimensional velocity field of a viscous incompressible flow and the problem of nonlinear friction

Abstract: An approximate theory is constructed to describe quasi-two-dimensional viscous incompressible flows This theory takes into account a weak circulation in the vertical plane and the related divergence of the two-dimensional velocity field The role of the nonlinear terms that are due to the interaction between the vortex and potential components of velocity and the possibility of taking into account the corresponding effects in the context of the concept of bottom friction are analyzed It is shown that the nonlinear character of friction is a consequence of the three-dimensional character of flow, which results in the effective interaction of vortices with vertical and horizontal axes An approximation of the effect of this interaction in quasi-two-dimensional equations is obtained with the use of the coefficient of nonlinear friction The results based on this approximation are compared to the data of laboratory experiments on the excitation of a spatially periodic fluid flow

Echo thresholds measured in the vertical and horizontal planes

Abstract: The results of studying the precedence effect in the case where the direct and delayed (reflected) signals are located in the vertical and horizontal planes are considered. Loudspeakers emitting direct and reflected sounds were placed 45 deg to the left and right of the median line of the subject’s head in the horizontal plane and in front of and above the subject’s head, i.e., with 0 and 90 deg of elevation relative to the eye level, in the vertical plane. It has been shown that the time limits of the precedence effect of short (5-ms) signals are similar in the horizontal and vertical planes. For signals more than 10 ms in duration, the values of echo thresholds were higher in the vertical plane and significantly differed (p < 0.05) from the thresholds in the horizontal plane.
