Superconducting machines concepts have been applied across diverse fields of engineering including electronics, power, instrumentation and others [4].
The cost of roads and civil work is generally depending on the machine rating: cost factor = 2.17 × 10-6(machine rating)2 – 0.0145(machine rating) + 69.54; and roads and civil work cost = (machine rating) × (cost factor).
The BOS cost includes the engineering permits cost and covers the cost of the entire facility: cost factor = 9.94 × 10-4(machine rating) + 20.31; and engineering and permits cost = machine rating × cost factor.
For balance of station (BOS) cost, the cost includes foundations, transportations, roads and civil works, assembly and installation, electrical connection and also the engineering permits.

Abstract.
Comparison with an isotropic material modeling suggests an improvement in a preliminary engineering design when plastic orthotropy is accounted for.
As concerning applications to many engineering problems, phenomenological approach takes important advantages like a unified structural level of mathematical modeling, easy assessable material constants through standard tests, etc.
Such a modeling is efficient on the preliminary engineering design stage of a series of industrial problems such as rotating machinery, gas turbines, high performance automotive, etc.

Abstract.
Introduction Using the carbon fiber reinforcement polymer (CFRP) to reinforce the concrete construction has a lot of advantages, such as strong strength, light weight, anticorrosion, convenience and the etc, which has been widely used in civil engineering.
As for the engineering application, these two measures are more practical than that of L-6.
Accompany with the broad application in civil engineering, it should not only be used in its good mechanical ability but also be developed in its corrosion protection ability fully.

Abstract.When the frequency response function (FRF) and Back-propagation (BP) neural network are used to identify the structural damage, problems such as the excitation information can not be got easily, the network is difficult to converge and the network stability is poor as the oversize input vectors.
The damage identification method with FRF and neural network will encounter some questions: (1) the dimensionality of the FRF with suitable precision is too large, when the complete FRF is used as input to the neural network, the size of the neural network is too huge to converge, (2) The excitation information is needed to gain the FRF, however, for actual engineering structure, it is difficult to test the excitation information which are complicated and easily influenced by several factors.
