Nowadays tunnel structural inspections are executed based on visual (human) inspections. This is a slow process, labor expensive and subjective, while requiring lane/rail shutdown during the inspection. ROBO-SPECT is an EC co-funded research project (FP7 ICT – 611145) that, driven by the tunnel inspection industry, adapts and integrates recent research results in intelligent control in robotics...
A procedure is developed to generate a large aerodynamic database suitable for the static stability analysis of launch vehicles in the transonic regime by using the Navier–Stokes equations. Effects of structural deformations are also included using modal representation. It is shown that a large number of cases suitable for design can be computed within practical time limitations by using effici...
Studying the characteristics of proteins and their inner void space, including their geometry, physico-chemical properties and dynamics are instrumental for evaluating the reactivity of the protein with other small molecules. The analysis of long simulations of molecular dynamics produces a large number of voids which have to be further explored and evaluated. In this paper we propose three new...
The load entering from the ground surrounding on the tunnel’s lining is one of the effective parameters in the designation of a tunnel. The amount of this parameter, which is called Rock load in a rocky environment, depends on several factors such as the overburden thickness, geological and geomechanical conditions and the depth of tunnel. In the present study, the amount of rock load for the L...
The large deformation of soft rock tunnel is one the key problems to be overcome in construction stage. In present study, mechanism a representative and some related countermeasures are investigated using field tests engineering geological analysis. Owing scarce performances methods based on other criteria such as small pipe spacing, anchor bolt length steel frame new support scheme implemented...
In this study, a numerical procedure is described for the transient response analysis of a submerged floating tunnel with reference of a designed tunnel in Japan. Tension legs seizing the tunnel are simply modeled by a spring elements and the tunnel itself is assumed by two rigid bodies between which a flexible joint is used. A recorded seismic excitation is used while the wave load is calculat...

A second-mode stability analysis has been performed for a hypersonic boundary layer on a wall covered by a porous coating with equally spaced cylindrical blind microholes. Massive reduction of the second mode ampli cation is found to be due to the disturbance energy absorption by the porous layer. This stabilization effect was demonstrated by experiments recently conducted on a sharp cone in t...
background: carpal tunnel syndrome (cts) is a compression neuropathy that causes paresthesia, pain or numbness in the territory of median nerve. the aim of this study is to compare the open surgery outcome and patients` satisfaction in carpal tunnel syndrome among diabetic and non-diabetic patients. methods: in a retrospective cohort study from april 2011 to june 2012, patients suffered from ca...
background: carpal tunnel syndrome is the most common neuropathy in the general population. nerve conduction studies are among the standard methods for diagnosing carpal tunnel syndrome. electromyography is painful and unpleasant, and if nerve conduction studies can be used to diagnose axonal injury in carpal tunnel syndrome, electromyography might be replaced. objectives: this study aimed to e...
