Abstract
The main problem about a railway analysis is detection of cracks in the structure.
If these de¯ciencies are not controlled at early stages they might cause huge economical problems
a®ecting the rail network (unexpected requisition of spare parts, handling of incident and/or
accidents). Within this framework, the early and continuous use of Non Destructive Tests can
be useful. In this context, Eddy Current Testing is increasing in importance and popularity.
Particularly, in this paper we exploit the measure of normal com ....etc

Design and Testing of Superconducting Microwave Passive Components for Quantum Information Processing
Abstract
We report on the design, fabrication and testing of
two superconducting passive microwave components, a quadrature
hybrid and a 20 dB directional coupler. These components
are designed to be integrated with superconducting qubits or
Josephson parametric amplifiers and used in quantum information
processing applications. For the coupler, we measure return
loss and isolation 20 dB, and insertion loss 0.3 dB in a 2 ....etc

ABSTRACT :-
A SQUID (for superconducting quantum interference device) is a very sen
isitive magnetometer used to measure extremely weak magnetic fields, based on superconducting loops containing Josephson junctions.
SQUIDs are sensitive enough to measure fields as low as 5 aT (5×10−18 T) within a few days of averaged measurements. Their noise levels are as low as 3fT•Hz-½. For comparison, a typical refrigerator magnet produces 0.01 tesla (10−2 T), and some processes in animals produce very small magne ....etc

Quantum Wells, Quantum Wire, and Quantum Dots




I'd like to explore the material known as Wellstone. There are some interesting aspects to this material, and it is written about in Hacking Matter by Will McCarthy. It is not necessarily nanotechnology, so much as it is quantum level materials and bio-molecular control over nano sized or meso-sized particles.
We will return to the world of Nanotechnology and DNA computing shortly, for now - let's talk about Wellstone.
