TiC-reinforced Ni 3Al composites were fabricated through thermal explosion reaction. The thermal explosion reaction process of Ti-C-3Ni-Al system and the composites were analyzed by differential scanning calorimetric(DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the reaction of titanium and carbon was ignited by the reaction of nickel and aluminum. Pure TiC/Ni 3Al products were synthesized by the thermal explosion. The reaction temperature of Ti-C-3Ni-Al system was independent of TiC contents. The system composition and thermal explosion temperature were found to have obvious influences on the morphology of the composites. With the increase of TiC contents, TiC particulates became coarser and the micro pores of the products decreased. The relative density of the products increased at first and then decreased with the rise of the thermal explosion temperature and TiC contents. The microhardness of the composite was revealed to be higher with higher TiC content.

Al-Ti-B-RE master alloy was prepared by casting of pure Ti. To improve the quality and reduce the cost of α- Al, the Al-Ti-B-RE master alloy was added to α-Al in molten and diluted state. The refining method had the advantages of shorter contact time and better refining effect. The array of the second phase particles was separated and the nucleating rate was greatly increased. Analysis and comparison of the refining effects were by X-ray diffraction (XRD), scanning electron microscopy (SEM) and optical microscopy (OM).The refining experiment showed that the molten and diluted state Al-Ti-B-RE by oneself had better grain refining performance and had obvious advantages over Al-Ti-B in domestic. © (2012) Trans Tech Publications, Switzerland.

By combining the current situation that China is seriously in shortage of the resources and has a very severe environmental pollution problem, the author carries out a study on the economic value of the recycled concrete, and then makes a qualitative and quantitative analysis on the economic feasibility of the recycled concrete. The analysis shows that the recycled concrete can save the aggregate resources and also can prevent the environmental pollution which is caused by the stacks of the waste concrete, and is a kind of green concrete featuring the sustainable development. Also, it is found that the economic feasibility of the recycled concrete can be embodied in the resource price, the urban garbage processing fees, and the governmental finance and taxation supports, etc. Therefore, it has been known that the production of the recycled aggregate is profitable and also is with a huge ecological benefit as well as a certain economic benefit. © (2012) Trans Tech Publications, Switzerland.

The conventional precision analysis method of modification and design is qualitative, laborious and time consuming. The precision of reverse parametric modification have direct influences on the quality of the reversed products. In this paper, a quantitative analysis method based on a reverse parametric approach and precision control concept is proposed. Combining with the ATOS scanner system, analyzing every aspect of the precision control and the error distribution, including data acquisition process, reverse reconstruction process and parametric process. In the process of the product reverse parametric modification, general error distribution is mainly composed of data acquisition error, reverse reconstruction error and parametric error. The method of precision control during the reverse parametric modification process is analyzed, according to this method, the total error of parametric modification for die face is 0.089mm, is lower than the accuracy requirement of 0.10mm in the reverse parametric modification process, the reverse modification of the die face of the blade based on precision control is realized. Validity and effectiveness of the method has been confirmed by case studies. © (2013) Trans Tech Publications, Switzerland.

Based on the SPOT satellite images of Jiangsu Province in 2007/2008, using models such as exploratory spatial data analysis and spatial metrics, the paper conducts a quantitative analysis of the space differentiation of rural settlements in Jiangsu Province, and further identifies the regional types. The results are shown as follows. In spatial distribution, the rural settlements in Jiangsu are characterized by obvious concentration with evident spatial variability, which is shown in the ladder-like sparse distribution towards the north and south in areas along the Yangtze River with high correlation in the overall distribution and geomorphic types. In the scale, the rural settlements in Jiangsu are generally in small scale with small difference in the scale of small villages and large gap in the scale of large villages which account for a small proportion. The rural settlements in Jiangsu are characterized by low concentration in size distribution, and is obviously presented in the "dumbbell" structure, namely, the rural settlements in northern and southern Jiangsu are in a large scale, and those in the central part are in a relatively small scale. In the spatial change of form and pattern, through the measurement of the pattern indices of the five transects in the northern, central and southern Jiangsu, the coastal area and areas along the Grand Canal, it was found that the form of the rural settlements in central Jiangsu is more complex than that in the northern and southern parts of the province, and the form of coastal area is more complex than that in areas along the canal. The rural settlements in southern Jiangsu and areas along the canal are characterized by good connectivity. The rural settlements in the five transects are significantly differentiated in distribution. Finally, through establishing the morphological measurement index system of the rural settlements, by adopting the method of hierarchical cluster, the rural settlements in Jiangsu are divided into eight types: Xulian hillock (low-density large-mass type), Suhuai plain (medium-density broad-band type), coastal reclamation area (high-density stripe type), polder area in central Suzhou (medium-density arc-belt type), plain south of the Yangtze River (medium-density small-mass type), lake mound land (low-density point-scattered type), Ningyi hilly region (cluster-like dispersal type), and Lixiahe area (low-density cluster-like type).

Identity authentication is the basis of the whole information security system, and also the bridgehead of network security. Traditionally, static password-based authentication schemes are very popular for identity authentication in remote access, but it cannot guarantee sufficient accessing security owing to its own shortcomings. In this paper, we present an improved dynamic password authentication protocol. This scheme uses a random number as challenge factors. It can support mutual authentication, resist decimal attack, and middleman attack and satisfy the security objectives such as data confidentiality, identity, and data authentication. © 2014 WIT Press.

Anatase TiO2 nanoparticles with the size of about 20 nm were synthesized using Ti(SO4)2 as titanium source and stronger ammonia water as precipitant at 240 °C for 48 h with pH=9 by a hydrothermal hydrolysis method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and ultraviolet-visible absorption spectroscopy (UV-VIS). XRD analysis shows that the phase of the sample is anatase TiO2. SEM and TEM analysis confirms that with the increase of the reaction time, the size of TiO2 nanoparticles prepared without stronger ammonia water can reach nanometer grade, but its change is not obvious. With the addition of stronger ammonia water, the size of TiO2 nanoparticles becomes small noticeabley. With the further increase of pH value, its influence on the TiO2 nanoparticles size is not obvious. And UV-VIS analysis shows that the reduction in the size of anatase TiO2 nanoparticles is beneficial to the blue shift of their absorption peak.
