Analytical bedded-beam spring model is most commonly adopted in the tunnel engineering practice due to its simplicity and promising outputs. Despite many well documented literatures exist concerning about theories fundamentals of various methods, there a dearth information on modelling framework details are often overlooked process. The main aim this paper produce soft ground, for both direct i...

The Na cluster has proven to be interesting from the experimental and theoretical point of view, and two of its electronic states, the and states, have been subject to several spectroscopic investigations. The state, and the ground state, are dominated by Jahn-Teller induced rovibronic effects, while in the state an almost free pseudorotational motion takes place. Although the two former states...

Maximum surface settlement (MSS) is an important parameter for the design and operation of earth pressure balance (EPB) shields that should determine before operate tunneling. Artificial intelligence (AI) methods are accepted as a technology that offers an alternative way to tackle highly complex problems that can’t be modeled in mathematics. They can learn from examples and they are able...

Efforts are made in this thesis to reveal the dynamics of single-electron tunneling and to realize quantum bits (qubits) in semiconductor quantum dots. At low temperatures, confined single quantum dots and double quantum dots are realized in the twodimensional electron gas (2DEG) of AlGaAs/GaAs heterostructures. For transport studies, quantum dots are coupled to the drain and source contacts vi...

Accurate, experimental rotational-vibrational energy levels determined via the MARVEL (Measured Active Rotational-Vibrational Energy Levels) algorithm and published recently for the symmetric-top (14)NH3 molecule in J. Quant. Spectrosc. Radiat. Transfer, 2015, 116, 117-130 are analyzed to unravel the promoting and inhibiting effects of vibrations and rotations on the tunneling splittings of the...
