this paper presents the results of engineering geological studies of rock blocks along a road tunnel in nw iran. the tunnel is to cross the western alborz mountain range through 530 m in length with 11.2 m span and 8 m height. eocene tuffs and andesites crop out in whole of the tunnel route. numerical analyses are done using, a 3d stability analysis and visualization program, called unwedge tha...

This paper has made a qualitative and quantitative analysis by establishing the tunnel fault tree and giving the minimal cut sets of the faults in tunnel, and tested the data in tunnel combined with artificial neural network. The fault detection mechanism in this article has been simulated by MatLab and processed a lot of the actual data through the tunnel operating history. Experimental result...

In this paper, simulation of fire in a short 2-lane road tunnel and its evacuation are described. Two traffic situations in the tunnel and their impact on people evacuation in fire conditions are analyzed. For simulation of the tunnel fire, the FDS (Fire Dynamics Simulator) system, version 5.5.3 based on advanced CFD (Computational Fluid Dynamics) fire model is used. The evacuation of people in...

Carpal tunnel release is required to treat patients with severe carpal tunnel syndrome. The regional anesthesia of the upper limb by brachial plexus block (BPB) may be a good alternative to general anesthesia for carpal tunnel release surgery, because it results in less complications. However, the regional anesthesia still has various side effects, such as hematoma, infection, and peripheral ne...

In this paper, the author studies about the traffic safety technology of highway tunnel group. In this study measured traffic safety technology in the access zone of tunnels including tunnel luminance under diverse climate conditions were measured and luminance of the threshold zone were estimated. Then operating traffic safety technology of tunnel in China was compared and analyzed and, based ...

Much research is currently being carried out in the field of nanoelectronic circuit design [1], [2]. One of the proposed quantum devices is the Single Electron Tunneling (SET) device. This SET device consists of a tunnel junction, through which only an integer number of electrons can tunnel. A new local tunnel condition will be derived in this paper. The derivation is based on the discrete char...

In order to solve the problems of large energy consumption existing in tunnel lighting control system, an automatic control system of tunnel lighting is designed based on stepless control method. The tunnel lighting control model is established based on “Specifications for Design of Ventilation and Lighting of Highway Tunnel (China)”. Simulation of tunnel lighting control based on the establish...

UNLABELLED The purpose of this cadaver study about the ACL graft was to compare a "Lateral Tibial Tunnel" (LTT) and a "classic, anteroMedial Tibial Tunnel" (MTT), as to fixation strength and mode of failure. Ten pairs of fresh frozen human proximal tibias were used. In one of both tibias a classic anteromedial tunnel was used, versus a lateral tibial tunnel in the contralateral knee. Autologous...

We report on the successful integration of low-cost, conformal, and versatile atomic layer deposited (ALD) dielectric in Ni–Al2O3–Co magnetic tunnel junctions (MTJs) where the Ni is coated with a spin-filtering graphene membrane. The ALD tunnel barriers, as thin as 0.6 nm, are grown layer-by-layer in a simple, low-vacuum, ozone-based process, which yields high-quality electron-transport barrier...
