The objective of this project is to fabricate and characterize nanoscale hybrid tunnel-junction structures that will reveal new physical aspects of the spin-dependent quantum states and dynamic behavior of single electrons. Several interesting effects have been predicted for spindependent transport in ferromagnet (FM)/metal/ferromagnet and FM/superconductor/FM double junctions. One goal is expe...

The paper introduces the potentiality of wireless communications in road safety improvement. New systems based on Vehicle/infrastructure and vehicle/vehicle cooperation are enabled. The results of a recent project “SAFE TUNNEL” and new projects like “SAFESPOT”, “GOODROUTE”,”WATCHOVER”, are described. All these research projects are co-funded by European Commission (EC) and witness the strong co...

This paper describes the use of photogrammetry to measure and quantify ice accretion on an aerofoil section. A series of stereoscopic photographs was taken during the ice accretion on the section in an icing tunnel. From measurements made on these photographs with a Kern (Leica) DSR 14 analytical photogrammetric plotter, a series of three dimensional models of the ice surfaces was constructed. ...

The determination of traffic and earnings which are to be antici­ pated for a proposed revenue bond highway project involves many standard traffic engineering techniques, supplemented by special investi­ gations of economic and sociological factors. Traffic considerations also play an important role in preliminary studies to determine the most feasible location for the facility, whether it be a...

The criteria as well as the methods and measurements of wind tunnel simulation on wind effects on air-cooled condensers in a power plant were discussed. The parameter of recirculation was suggested to describe the wind effects on the efficiency of the condenser. The result of practical project models shows that great wind effects of both wind speed and the angle of the incident flow on the effi...

This research project sought to determine the e ects of an added degree of mechanical freedom to the tunnel splitting of a single molecule magnet. We consider both mechanical rotation and vibration (ie tortional oscillations) with the later consisting of an analytical and numerical portion which appear thus far to be in good agreement. The rst part of this paper will discuss some background inf...

See the difference. Use 3D models based on proven transportation engineering design with Bentley software. When building the 5.6 billion dollar Airport Link, Northern Busway and Airport Roundabout Upgrade project, the Parsons Brinckerhoff Arup Joint Venture team delivered the design and carried out the construction in record time. Using Bentley’s broad range of road, bridge, tunnel, geotechnica...

A novel optimization methodology for the disc cutter designs of tunnel boring machines (TBM) was presented. To fully understand the characteristics and performance of TBM cutters, a comprehensive list of performance parameters were investigated, including maximum equivalent stress and strain, specific energy and wear life which were closely related to the cutting forces and profile geometry of ...
