Authors: Zeng Fan Guang , Wu Guang Min , Mai John D. , Chen Jian Ming
Published: January 2014

Phase unwrapping (PU) is a difficult task commonly found in applications involving interferometric synthetic aperture radar (InSAR), magnetic resonance imaging (MRI) and optical surface profile measurements; all of which involve mathematically ill-posed problems. Conventional algorithms exhibit strong shortcomings in PU when phase discontinuity flaws exist. To simulate these situations, we are custom-designed test data with a phase discontinuity flaw. This simulated data is a 3D Gaussian distribution with an arc-shaped notch as a phase flaw. PU is carried out by Bayesian inference and MRF (Markov Random Field) modeling. A graph cut algorithm is employed for optimization with respect to energy minimization. Three other conventional algorithms are also employed and their PU performance is compared. The results show the good performance and effectiveness of the Bayesian MRF modeling method. These experimental results are important references for phase unwrapping problems when phase discontinuities exist.

Thermal degradation characteristics of the paraffin, pre-treated paraffin and HTPB were studied; Influences of different pressure and different temperatures on thermal degradation characteristics of pre-treated paraffin were analyzed. Experiments show that the decomposition temperature of pre-treated paraffin is higher than that of the untreated paraffin, but lower than that of HTPB; the initial reaction temperature, the reaction exothermic peak temperature and the reaction heat release of pre-treated paraffin were all affected by pressure and heating rate; Kinetic parameters of pre-treated paraffin in oxygen atmosphere were calculated.

Published: January 2014

According to the vibration in a residential building, a field investigation was conducted. Using the elimination strategy, the primary vibration source was determined, the vibration serviceability of the residential building was assessed by the environmental vibration tests, and the measures for vibration reduction were proposed. The results show that the vibration in the residential building is caused by 5 textile mills nearby, among which, Mill II has significant effect on the residential building. By applying the measures for vibration reduction to Mill II and reinforcing the residential building, the vibration serviceability can be improved.
Secondary Moment Distribution of Prestressed Concrete Slab
Authors: Pang Ping
Published: January 2014

In this paper, the multi-span continuous two-way slab is analyzed with finite element method of the secondary moment distribution characteristics. When the support beam size changes, affect secondary moment in the plate. Drawn by the existence of the beam, different size of the beam has a great influence on the board secondary moment values. Likewise, threatening the secondary moment in beam may also be affected. Suggestions in the actual engineering design, not only in the beam slab should be considered themselves times the size of the bending moment, should also be considered secondary moment of mutual influence between beam and slab.

Taking Liang Zhuang phyllite tunnel as the research object, the paper tries to analyze the variation rules of formation stress and initial support stress in the construction process based on numerical simulation of surrounding rocks grade III, IV and V, and also by using the measured data to have a better analysis of the stress state of surrounding rocks and support in the construction process, thus to grasp the rules for better construction. The result shows that the maximum compressive stress of initial support increases in the process of excavation, while the maximum formation stress is relatively stable in the process of excavation, with a slightly down trend, and whether there is a rock bolt or not, it doesnt have an obvious effect on the distribution and size of initial support stress.

Published: January 2014

In order to reveal the mechanical properties of the subgrade fillers, they are studied by screening test of coarse-grained soils, compaction test and large-scale triaxial test in the track-subgrade model in high-speed rail laboratory of Central South University. The experimental results show that the coarse particle content for filler of the bottom layer is larger than that of the underlying embankment. The optimum water content of the filler of the bottom layer is less than that of the underlying embankment, while the maximum of dry density is similar, All samples have shown strain hardening characteristic, the higher the confining pressure is, the more obvious the strain hardening characteristic is. the volumetric strain of samples changes from shear contraction to shear dilation with the increment of axial strain. The cohesion and internal friction angle for filler of the bottom layer is greater than that of the underlying embankment. The tangent modulus for filler of the bottom layer is larger than that of the underlying embankment, and with the confining pressure increases, the difference also increases.
The Relationship between Taiwan Green Buildings, Humanity and Aesthetics

Published: January 2014

The Taiwan Green Building Rating System is composed of the four categories of Ecology, Energy Saving, Waste Reduction and Health. There are also nine indicators, which are mainly guidelines but fail to consider humanity and the aesthetics of the buildings and urban environment. Based on a review of relevant literature and professional seminars, the questionnaire that was edited according to proposals relating to Green Building Aesthetics made by professionals in the field and then used to analyze the current relationship between green buildings, humanity and aesthetics in Taiwan. It is hoped, that this will enable us to fully explore the impact of humanity and aesthetics on Taiwan Green Buildings, while further demonstrating the importance of humanity and aesthetics. According to the questionnaire results, 76.8% of the respondents disagreed as well as kind of agreed and disagreed with the idea that the current Green Buildings in Taiwan has comprised of the concepts of Humanity and Aesthetics; 72.1% of the respondents considered Humanity and Aesthetics to the rating of Green Building very important and important; 81.2% of the public extremely agreed and agreed with the idea that Humanity and Aesthetics should be included in Green Building. The findings of this research indicated that most of the public considered that there were only few Humanity and Aesthetics considerations in the current Green Buildings in Taiwan and agreed that it was important to include Humanity and Aesthetics in Green Buildings.

Published: January 2014

The rapid growth of road traffic brings some requirements on driving comfort and safety, which include good smoothness, skid resistance and reduced noise of the pavement. SMA has adequate structure strength to reduce rutting and provide superior surface function of skid resistance. Modified asphalt as mixture binder, has considerable durability to ensure the service life with less maintenance costs. Associated with laboratory test and trial section, some suggestion and requirements are brought forward in this paper for the material properties and mixture design of SMA on the FuZhou-JiAn expressway in Jiangxi Province.
