We present a review, together with new results, of a universal forcing of oscillatory systems, termed 'rocking', which leads to the emergence of a phase bistability and to the kind of pattern formation associated with it, characterized by the presence of phase domains, phase spatial solitons and phase-bistable extended patterns. The effects of rocking are thus similar to those observed in the c...

X-ray rocking curve and topograph measurements were carried out at CHESS in Cornell University in November 2006. The purpose of this experiment was to check if the X-ray facility at CHESS is suitable to be used for GlueX in assessing diamond crystal quality and investigating radiation damage and surface deformation induced by milling. After modifying the C1 beam line by using an asymmetry silic...

Properties of the wall impedance of a storage ring are studied for a low relativism, 1 1: Both broad and narrow band impedances are shown to be damped at low energies, the damping factors are found. Coherent motion of a coasting beam is discussed; Landau decrements are calculated.

This research investigates the convenience of structural identification tools to detect rocking motion tendency, using as input response ambient vibrations. The ratio and spectrum are proposed original highlight its frequency content. procedure allows detection quantification only building vertical records in both cases vibration earthquake. First, three-dimensional finite element models reinfo...

Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive impact on the seismic behavior of structural systems, but their design makes them susceptible to concrete crushing around their base, which can lead to significantly advers...

Introduction This application guide addresses the limiting conditions of connecting transformers in parallel and loading considerations when turn ratios, impedances, and kVA ratings are different. Most transformers installed in parallel have the same kVA, turn ratios, and impedances, which can make it difficult for power engineers in industrial and commercial facilities to understand circulatin...

where E is the longitudinal electric field and Ex,y and By,x are the transverse electric and magnetic fields excited by the beam. Coupling impedances can be determined through bench measurement [1], analytically [2] or numerically by solving a discretized form of Maxwell’s equations [3]. This work focuses on finding suitable methods for the numerical calculation of coupling impedances for the r...

As every circuit designer knows, the flow of energy is governed by impedance matching. Classical or quantum impedances, mechanical or electromagnetic, fermionic or bosonic, topological,... To understand the flow of energy it is essential to understand the relations between the associated impedances. The connection between electromagnetism and gravitation can be made explicit by examining the im...

(1998) Rocking chair therapy for dementia patients: Its effect on psychosocial well-being and balance

Abstract Introduction Passive rhythmic movement–rocking – is found to enhance sleep, particularly in infants and young wild type (WT) mice. Rocking can potentially sleep at all ages, with the added benefit of being non-invasive, easy translate for human use, negligible side effects. Furthermore, enhancement tools should be especially valuable patients disturbances, a pervasive feature age-relat...
