Transmission tunneling

Foams of PP are used for side protection of doors, armrests with integrated baby seat, floor insulation, heat and phonic insulation of transmission tunnels, trunks, cushioning of sun visors, steering columns, knee bolsters, armrests, tool boxes and racks. .. 

High pressures on the tunnel lining in the long term can lead to structural or functional failure of these supports. During the construction of water transmission tunnel in Yacambu, Venezuela (Wittke et al. 2005), the two open type TBMs faced extremely unstable ground conditions associated with high and rapid squeezing of the tunnel walls (see Fig. 2).

Aston Martin has used carbon fiber in their Vanquish model for the transmission tunnel, windshield pillars and parts of the sub-frame. 

The Volt battery is designed to fit into the transmission tunnel and fuel tank areas in a T -shaped pack design (Figure 7.5). It mormts outside of the cabin of the vehicle and is... 

The drive systems powering the BMW i8 Concept (Figure 10.6) are integrated in the front and rear axle modules, with the carbon fiber-reinforced plastic Life module providing a bridge between the two. The battery cells are stored in the Life module inside an energy tunnel, a structure similar to a central transmission tunnel. 

The probability matrix plays an important role in many processes in chemical physics. For chemical reactions, the probability of reaction is often limited by tunnelling tlnough a barrier, or by the fonnation of metastable states (resonances) in an intennediate well. Equivalently, the conductivity of a molecular wire is related to the probability of transmission of conduction electrons tlttough the junction region between the wire and the electrodes to which the wire is attached.

A different ion guide is the ion tunnel, which also uses only RF fields to transmit ions. It is not a rod device but consists of a series of concentric circular electrodes. It is perhaps best described as operating like a series of ion traps. This chapter gives details of some of the fundamental characteristics of rod-type transmission guides (multipoles). 

Many computational studies in heterocyclic chemistry deal with proton transfer reactions between different tautomeric structures. Activation energies of these reactions obtained from quantum chemical calculations need further corrections, since tunneling effects may lower the effective barriers considerably. These effects can either be estimated by simple models or computed more precisely via the determination of the transmission coefficients within the framework of variational transition state calculations [92CPC235, 93JA2408]. 

Underground transmission lines are preferred in places where rights-of-way are severely limited because they can be placed much closer together than overhead lines. They are also favored for aesthetic reasons. They may be directly buried in the soil, buried in protective steel or plastic pipes, or placed in subterranean tunnels. The conductors are usually contained within plastic insulation encased in a thin metallic sheath. The conductors enclosed in steel pipes may be immersed in oil, which may be circulated for cooling purposes. For all types of underground lines, the capacitance is higher than for overhead lines, and the power transfer capability is usually limited by the resistive losses instead of the inductance.

In the case where they represent quantum vibrational modes, this leads to the appearance of a small tunnel factor in the transmission coefficient k. ... 

The term exp[iax] in equations (2.47) indicates travel in the positive x-direction, while exp[—iax] refers to travel in the opposite direction. The coefficient A is, then, the amplitude of the incident wave, B is the amplitude of the reflected wave, and F is the amplitude of the transmitted wave. In region III, the particle moves in the positive x-direction, so that G is zero. The relative probability of tunneling is given by the transmission coefficient T... 

The transmission coefficient T in equation (2.58) is the relative probability that a particle impinging on the potential barrier tunnels through the barrier. The reflection coefficient R in equation (2.59) is the relative probability that the particle bounces off the barrier and moves in the negative v-direction. Since the particle must do one or the other of these two possibilities, the sum of T and R should equal unity...
