Providing Invariance to Disturbing Effects in Rail Lines

Disturbing behavior: neurotoxic effects in children.

A n epidemic of neurobehavioral problems is sweeping through children today. According to In Harm s Way: Toxic Threats to Child Development, a May 2000 report published by the Greater Boston Physicians for Social Responsibility, 12 million American children suffer from learning, developmental, or behavioral disabilities. Specifically, these disabilities may include attention-deficit/hyperactivi...

Price Elasticity of Demand in the High Speed Rail Lines

Reduced travel time, regional cohesion, economic development and environmental benefits were some of the reasons given to develop the High Speed network in Spain, the largest in Europe. Ever since the opening of the first High Speed line in 1992, High Speed Rail (HSR) have become a new travelling experience despite the fact that in the recent years several voices have raised concerns over a lac...

High resolution rail-to-rail ADC in CMOS digital technology

This paper discusses the design issues for an high resolution rail-to-rail analog-to-digital converter. The circuit proposed uses conventional digital technology (without precise capacitors) and allows 12 bits of resolution to be achieved using 2.4 V bias and 2.4 V input dynamic range. The proposed architecture is based on the successive algorithm technique and uses a rail-to-rail autozeroed co...

Disturbing Vortices

Inviscid spatially compact vortices (such as the Rankine vortex) have discrete Kelvin modes. For these modes, the critical radius, at which the rotation frequency of the wave matches the angular velocity of the fluid, lies outside the vortex core. When such a vortex is not perfectly compact, but has a weak vorticity distribution beyond the core, these Kelvin disturbances are singular at the cri...
