Parameters used for prediction of settlement trough due to TBM tunnelling [PDF]

Archives of Civil Engineering, 2021
One of major design problems associated with shallow tunnelling in urbanized areas is the prediction of ground displacements caused by the construction process.

Reflectionless Tunnelling of Light in Gradient Optics [PDF]

, 2005
We analyse the optical (or microwave) tunnelling properties of electromagnetic waves passing through thin films presenting a specific index profile providing a cut-off frequency, when they are used below this frequency. We show that contrary to the usual

Research on Shield Tunnelling Parameters Correlation in Composite Strata

Advances in Materials Science and Engineering, 2022
Shield tunnelling has become the development direction of tunnel construction due to its safety, economy, and speed. The complex formation has complicated geological changes, including soft rock, hard rock, and soft and hard inhomogeneous formation.

Recognition tunneling [PDF]

Nanotechnology, 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 ...

Experimental and numerical analysis of thermal comfort in high-geothermal tunnel rest rooms

Case Studies in Thermal Engineering
In high-geothermal tunnel construction, rest rooms play a critical role in safeguarding workers' health and operational safety. To elucidate the thermal comfort characteristics of these spaces, a comprehensive questionnaire survey was administered to ...

Landau-Zener Tunnelling in a Nonlinear Three-level System

, 2006
We present a comprehensive analysis of the Landau-Zener tunnelling of a nonlinear three-level system in a linearly sweeping external field. We find the presence of nonzero tunnelling probability in the adiabatic limit (i.e., very slowly sweeping field ...

Environmental Impacts of Road Traffic and Route Variants: An Accurate Way to Support Decision-Making Processes of Mountain Roads and Tunnels in Austria

Buildings
Traffic contributes nearly 25% of global greenhouse gas emissions. For designing new traffic routes and decision-making processes, it is essential to incorporate integral life cycle assessments (LCAs) to ensure sustainable solutions and to achieve the UN

Fermions Tunnelling from Black Holes

, 2008
We investigate the tunnelling of spin 1/2 particles through event horizons. We first apply the tunnelling method to Rindler spacetime and obtain the Unruh temperature.
