Interval Finite Element Analysis and Sensitivity Study of Engineering Structure Shijun Liu1,a Wenfeng Duan2,b Hongchun Wang1,c 1 College of architecture and engineer, Anhui Polytechnic University, Anhui Wuhu, China, 241000 2 College of civil engineering, Hunan University, Hunan Changsha, China, 410082 aJunshiliu2005@163.com, bduanwenfeng@163.com, cwanghongchun@163.com Key words: uncertainty, interval finite element method, interval sensitivity, truss structure Abstract: The material parameters and the load are considered interval uncertainty and regarded as interval variables in this paper.
The interval finite element analysis model is established for engineering structures.
Introduction Engineering structure analysis and design method is based on the identified structure parameters and mathematical models at present.
But in the actual engineering, there exist many errors or uncertainties related to material properties, geometry, loading conditions, initial conditions and boundary conditions.

The aim of this work is about establishing and analyzing the Hamiltonian for entangled photon generation in a micro PANDA ring resonator for a quantum key generation unit in quantum cryptography processing.
In addition, time dependent noise current in quantum electronics aspect from the photodetector will also be investigated theoretically.Model and Method In quantum information engineering, the heart of logic processing depends on quantum bits or qubits such as atomic spin qubits or polarized photon qubits.
The system Hamiltonian of photons in the nonlinear micro ring resonator can be expressed in the form ˆH = i}(χˆa†sˆa†d − χ∗ˆasˆad), (5) where h (} = h/2π) is Planck's contant, ω is photon angular frequency, s is a signal mode, d is an idler mode and χ is a nonlinear susceptibility of material.
Conclusion In this work, qubit noise within micro PANDA ring resonator prepared to quantum key distribution purpose was studied.
The reduced density operator, divided into two parts, with noise parameter strength was also simulated for optimum option of enhancement quantum key distribution.

Since ceramic tool materials are fabricated from several raw powders by means of the hot-pressing technology, the mechanical properties of the ceramic tool materials are governed by the compositions, as well as by the microstructure.
The starting homologous temperature for sintering materials is 0.5.

Firstly, based on result of core testing under normal temperature, I determined the best mix-proportion for three materials, and tested their shear, tensile strength, deformation performance under different temperature and humidity.
In order to verify the applicability of these three waterproof adhesive layers in seasonal frozen area of the bridge deck, the key performance parameters of the optimal mix of materials were tested under different temperatures and humidity conditions.
The results showed that the three optimal mix of waterproof adhesive layers materials identified in the program can meet the seasonal frozen region bridge deck requirements.

The proposed method is applied to an actual load time history signal of engineering vehicle.
The working environments of engineering vehicle are bad.
The threshold setting is the key of wavelet denoising.
The conventional wavelet-based threshold denoising can not satisfy practical engineering application.
