The seismic response of acceleration-sensitive non-structural components in buildings has attracted the attention a significant number researchers over past decade. This paper provides results which improve state-of-knowledge influences that higher vibration modes structures and nonlinearity have on floor acceleration demands. In order to study these influences, response-history analysis code-d...

1. Peak blood flow acceleration measured in the common carotid artery was compared with peak flow acceleration measured in the ascending aorta of three baboons. 2. The response to occlusion for 60s of the circumflex branch or the anterior descending branch of the left coronary artery was investigated. 3. Both accelerations decreased approximately to the same extent. Peak aortic flow velocity, s...

The present study investigates how the CNS deals with the omnipresent force of gravity during arm motor planning. Previous studies have reported direction-dependent kinematic differences in the vertical plane; notably, acceleration duration was greater during a downward than an upward arm movement. Although the analysis of acceleration and deceleration phases has permitted to explore the integr...

Dynamic properties and control strategies of step responses by accommodation and disaccommodation differ from one another. Peak velocity of accommodation increases with response magnitude, while peak velocity and peak acceleration of disaccommodation increase with starting position. These dynamic properties can be modeled as control strategies that use independent acceleration-pulse and velocit...

We study the van der Waals (vdW) interaction between a polarizable particle and grounded conducting corrugated surface. For sinusoidal corrugations, one knows that, under action of lateral vdW force, an isotropic is always attracted to nearest corrugation peak, with such behavior called in present paper as peak regime. Here, considering anisotropic particle, making analytical calculations valid...

In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...

The dynamic response of a series of base-isolated systems subjected to ground motions that were recorded in firm soils located inshore of the Mexican Pacific was estimated in order to evaluate the influence of the structural properties of these systems in their floor acceleration demands. While the super-structures were assumed to remain elastic, the energy dissipation capacity of the base-isol...
