Evaluation of innovative sprayed-concrete-lined tunnelling [PDF]

open access: yes, 2008
The front-shunt tunnel was the first tunnel of the Terminal 5 project at Heathrow to be constructed, and was the first section of sprayed-concrete-lined (SCL) tunnel to be constructed using the method known as LaserShell.

Deduction of temperature fluctuations in transient compression wind tunnels using incompressible turbulent flow data [PDF]

open access: yes, 2009
Wind tunnels and other aero-thermal experimental facilities are likely to make a contribution to the optimisation of energy and propulsion systems for the foreseeable future.

Investigation on Seismic Response of Long-Span Special Steel Truss Cable-Stayed Bridge

open access: yesAdvances in Civil Engineering, 2022
Due to the small self-weight of the steel truss cable-stayed bridge with a single tower and a single cable plane, the torsional stiffness and wind stability of the structure are reduced. The arrangement of the deck type makes the mechanical properties of

Tunnel magnetoresistance in alumina, magnesia and composite tunnel barrier magnetic tunnel junctions

open access: yes, 2010
Using magnetron sputtering, we have prepared Co-Fe-B/tunnel barrier/Co-Fe-B magnetic tunnel junctions with tunnel barriers consisting of alumina, magnesia, and magnesia-alumina bilayer systems. The highest tunnel magnetoresistance ratios we found were 73%

Can the outside-in half-tunnel technique reduce femoral tunnel widening in anterior cruciate ligament reconstruction? A CT study [PDF]

open access: yes, 2017
There are different techniques for drilling the femoral tunnel in the anterior cruciate ligament reconstruction (ACLR), but their influence in the bone tunnel enlargement in unknown.

Recognition tunneling [PDF]

open access: yesNanotechnology, 2010
Single molecules in a tunnel junction can now be interrogated reliably using chemically functionalized electrodes. Monitoring stochastic bonding fluctuations between a ligand bound to one electrode and its target bound to a second electrode ('tethered molecule-pair' configuration) gives insight into the nature of the intermolecular bonding at a single ...

Tunnel spin polarization of Ni80Fe20/SiO2 probed with a magnetic tunnel transistor [PDF]

open access: yes, 2006
The tunnel spin polarization of Ni80Fe20/SiO2 interfaces has been investigated using a magnetic tunnel transistor (MTT). The MTT with a Ni80Fe20/SiO2 emitter shows a magnetocurrent of 74% at 100 K, corresponding to a tunnel spin polarization of the ...

Ex-situ Tunnel Junction Process Technique Characterized by Coulomb Blockade Thermometry [PDF]

open access: yes, 2010
We investigate a wafer scale tunnel junction fabrication method, where a plasma etched via through a dielectric layer covering bottom Al electrode defines the tunnel junction area. The ex-situ tunnel barrier is formed by oxidation of the bottom electrode
