This paper explores the effectiveness of shape memory alloy (SMA)/rubber-based isolation systems for seismic protection of bridges against near-field earthquakes by performing a sensitivity analysis. The isolation system considered in this study consists of a laminated rubber bearing, which provides lateral flexibility while supplying high vertical load-carrying capacity and an auxiliary device...

This paper shows a new design and prototyping method for pneumatic rubber actuators. The method enables us to design pneumatic rubber actuators optimally and efficiently based on static analysis using non-linear finite element method, in which geometrical and material non-linearity are considered and also enables us to prototype them rapidly and efficiently by a CAD/CAM based rubber moulding pr...

This report evaluates the effectiveness of rubber-asphalt and ebonite-asphalt mixes based on a review of published literature and unpublished reports. It discusses in detail various aspects of these mixes, including: diffe ent applications, physical properties, experiences of state highway agencies, and claimed advantages and problems associated with their use. The addition of ground tire rubbe...

Rubber tree (Hevea brasiliensis) self-rooting juvenile clones (JCs) are promising planting materials for rubber production. In a comparative trial between self-rooting JCs and donor clones (DCs), self-rooting JCs exhibited better performance in rubber yield. To study the molecular mechanism associated with higher rubber yield in self-rooting JCs, we sequenced and comparatively analyzed the late...

The rubber hand illusion is one reliable way to experimentally manipulate the experience of body ownership. However, debate continues about the necessary and sufficient conditions eliciting the illusion. We measured proprioceptive drift and the subjective experience (via questionnaire) while manipulating two variables that have been suggested to affect the intensity of the illusion. First, the ...

In this apparatus a piece of paraffined twine passes from the cork float a to the bottom of the reservoir, then through a stationary tube b, and is fastened to the dripping unit d. The dripping unit d descends at the same rate as the level of the solution in the reservoir, since it takes up the slack of the cord which leads from the float a. The descent of the dripping unit is made possible by ...

Rubber friction is critical in many applications ranging from automotive tyres to cylinder seals. The process where a static rubber sample transitions to frictional sliding is particularly poorly understood. The experimental and simulation results in this paper show a completely different detachment process from the static situation to sliding motion under dry and lubricated conditions. The res...
