Bioenergy from plants could make a substantial contribution to alleviation of global problems in climate change and energy security. The rapid growth rates of hybrid poplar (Populus spp.) exhibit a great potential for biofuels and selecting superior clones is critical to increase biomass production and ecological effects. Variation in growth, chemistry and calorific value of the 25 poplar clones were examined at nursery stage. The significant clonal differences in growth, leaf traits, wood basic density, chemical compositions and calorific values were observed among the 25 clones. Total leaf area per plant varied along a two-fold range (7146.7-18065.0cm2), mean single leaf area varied between 273.4 and 496.9cm2 and specific leaf area ranged from 158.7 to 204.9cm2g-1. After one growing season, the mean stem biomass production per plant ranged from 173.5g to 485.8g, while the average wood basic density varied from 224 kgm-3 to 310kgm-3 among the tested clones. Mean gross calorific value of the stem on an oven-dry weight basis was within the range of 18.5-19.1kJg-1, while mean ash free calorific value varied between 18.7 and 19.3kJg-1. All the chemical compositions measured both in stem wood and stem bark also presented a broad variation and clonal effects. Based on a comparison of component score coefficients, twenty-five hybrid clones were classified into four distinct groups by means of hierarchical cluster analysis, and clones 208, 328 and 75 showed excellent growth and combustion traits. Clones for further long-term trials in large-scale were also recommended to reduce loss of superior genetic material and risks of maladaptation. © 2012 Elsevier Ltd.

There are intensive distribution pebbles with high bearing capacity in Urumqi, Therefore, the lateral friction is usually ignored, but the tip resistance is attached importance during pile foundation design in the region. However, it is difficult to accurately obtain the mechanical properties of tip soil by traditional deep load test. The self-balance load test method was used according to the advantage of testing tip resistance. Based on the test results and the corresponding codes, the tip resistant normal value and the tip resistant characteristic number were obtained. Besides, the design project has been optimized according to the achievements of the test. The experience for similar projects of deep level plate load in pebble bed area using self-balance load method was obtained.

The fiber-optic sensor based on Mach-Zehnder interferometer is used in the perimeter alarm system. It can be used for alarming the vibration signal which occurs in the sensing area and has a very high sensitivity. In order to reduce the false alarm rate of perimeter alarm system, for signal processing of perimeter alarm system, by applying the wavelet transform method, the voltage signal outputted by the perimeter alarm system is identified, which could not only filter the noise signal but also retain mutant signal and distinguish very well the vibrations produced by deliberate invasion and rain to reduce false alarm rates of the perimeter alarm system and realize the deliberate invasion positioning. It is a breakthrough for the perimeter alarm system to realize engineering application. A large number of experimental results showed that it could reflect the singular value of measurement signals and remarkably reduce the false alarm rate of perimeter alarm system based on wavelet transform method to analyze signal of perimeter alarm system.

To provide a theoretical basis for the optimization design of the composite foundation, we analyzed the long-pile length of rigid-long-pile & flexible-short-pile composite foundation using finite element software ANSYS as well as the effects on the whole performance of the composite foundation. The results show that under same vertical load, foundation settlement was significantly reduced with increase of long-pile length when long-pile length is less than 20m, but when the long-pile length is more than 30 m, reduction amplitude of settlement decreases significantly. When the long-pile length increases from 10m to 30m, stress distribution of the pile is similar in shape, with slowly increase of the values. It proves that long-pile length is an important parameter affecting reliability and economy of composite foundation, foundation settlement decreases with the increase of long-pile length, but if the long-pile length is longer than the effective pile length, the settlement of composite foundation will be little change. © (2013) Trans Tech Publications, Switzerland.

In process of the pedestrian volume statistics for public places, in order to effectively remedy the defects of low detection efficiency, high false alarm rate and insufficient timeliness caused by pedestrian occlusion and congestion to pedestrian identification, a pedestrian identification model with a double-layer composite structure is designed in this article to coordinate and extract aggregated B-Haar features and Edgelet features, wherein the upper layer of the model has a complete binary tree structure which is integrated with Haar features (called aggregated B-Haar features) improved by local binary pattern and is mainly responsible for extracting the candidate pedestrian targets to ensure relatively high detection and identification rate; the lower layer is in a four-branch serial tree structure and meanwhile adopts Edgelet features and Bayesian principle to establish the tree decision structure so as to carry out multi-feature detection for the candidate pedestrians and further judge whether the candidate targets are pedestrians or not, thus to realize low false alarm rate and ensure the timeliness of the targets. Experimental analysis shows: compared with traditional tree structures and serial-parallel structures, the pedestrian identification method based on multi-feature synergetic double-layer composite structure in this article has significant advantages in the aspects of timeliness, detection rate and false alarm rate. © 2016, UK Simulation Society.

Residential buildings account for a large share of global carbon emission, while they play important roles in economic growth and social development at the same time. Therefore, the appropriate evolution routes of residential buildings need balancing their carbon emission and value creation, which is realized in this paper by creating a new concept of life-cycle carbon efficiency and its relative methodology. First, the life-cycle carbon efficiency of a residential building is defined as the ratio of its life-cycle value to carbon emission, and the life-cycle of a residential building is divided into five stages, including construction materials preparation, building construction, building operation, building demolition, and construction & demolition wastes disposal. Second, the life-cycle carbon emission of a residential building is estimated through calculating the carbon emission at each stage based on its consumed energy and resources. Third, the product of the service life span of a residential building (in year), its building area (m2) and its storey height (m) is recommended to represent its life-cycle value, since this product is a physical measure and more useful to develop action plans to improve its performance. In the end, the proposed methodology is exemplified in estimating the life-cycle carbon efficiency of a five-storey brick-concrete residential building in Nanjing city (China) at its design phase. Possible measures to enhance the estimated carbon efficiency are further put forward, such as prolonging the service life span, enhancing 3R (reduce, reuse and recycle) principles of cement and rolled steel, saving electricity and natural gas at the stage of building operation. © 2012 Elsevier Ltd.
