Authors: Peng Fei Jin , Huang Xiao Yun , Huang Hong Yuan , Xie Zhi Wen
Published: March 2015

Power quality disturbance detection and identification is the prerequisite and basis for the power quality management and control. This paper presents a new power quality disturbance detection and classification method. Firstly, the time-time transform is applied to power quality disturbance signal analysis. According to spectrum analysis results of the diagonal elements of time-time transform matrix, a preliminary judge about whether the disturbance signal contains harmonics and inter harmonic was given. For disturbances with non-harmonics, based on time-time transform modulus matrix diagonal sequence, the beginning and ending time of the disturbance is located, and the disturbance amplitude is calculated. For the disturbances which contain harmonics, time-time transform is perform twice to get the row mean value curve and the column mean value curve, which are required by disturbance time location and amplitude measurement. Finally, disturbance classification had realized by using rule tree. Simulation results reveal that this method is very robust and adaptable, which can identify transient power quality disturbance with minor magnitude under noisy environment, and the recognition rate is satisfactory.

Published: March 2015

Heavy metals will be released to the water column during the sediment resuspension, causing the secondary pollution to the water ecosystem. In this study, the sediment collected from Zhushan Bay was placed in three similar pneumatic annular flumes where the wind speeds supplied by blast blowers were 3.21m/s, 5.95m/s and 8.78m/s respectively. The physicochemical parameters of the water and concentrations of metals in the water, plants and sediment were measured during the relevant experiments. The result showed that the concentrations of metals in the overlying water increased while it decreased in the pore water with the hydrodynamic disturbance. The aquatic plant Vallisneria natans bioaccumulated metals in the sediment and water, and the plant roots showed a higher ability in assimilating metals than the leaves. Meanwhile a positive correlation was found between wind speed and release amount of metals in pore water. In addition, the relationship between the wind speed and the biota-sediment accumulation factor (BSAF) was different due to the different features of metals.

Authors: Piaskowska-Silarska Małgorzata , Depešová Jana , Noga Henryk , Pytel Krzysztof , Migo Piotr
Published: March 2015

Experimental data reveal that dry filters utilizing filter papers tend to change their operational characteristics whilst in service. When the airflow stream in the filter is constant, the pressure losses, and hence energy losses, will increase. On the other hand, when a constant pressure head is maintained to induce the flow, the flow rate of the flowing medium will decrease. A possible solution is a filter made from several filtering layers, their density varying along the dusted air flow path. Basing on the theory of filtration, the density of filter layers shall be chosen such that the amount of particulate matter settling on individual filter layers should be identical. The paper summaries the results of experimental testing of five-layered filters. Of particular interest is the distribution of collected dust mass along the airflow path in the filter in relation to the layer density.

Authors: Wang Bing , Yuan Xu Yin , Zhao Xue Qiang , Wang Shou Quan , Chen Hai Long
Published: March 2015

Mafic tailing is one of the common tailings in China which appears around metal-bearing mines with ultrabasic and basic rocks. These tailings are enriched in Cr, Ni, Cu, Mn and Zn comparing with other tailings.Phytoremediation is a method which can remove or reduce trace metals by plant uptake in tailing yard. This paper studies the concentration changes of Cr, Ni, Cu, Mn and Zn in mafic tailings of experiment pots and bioaccumulation during Imperata Cylindrical growth. The results indicate that serpentine-type tailings are more suitable for the growth of plants due to their completely weathering and higher organic matter than other tailings. The concentration of Ni is higher than other metals in Imperata Cylindrical and Ni in root is more easily transfer to leaf. The acid-soluble form percentages of Ni, Zn, Cu and Cr decrease after experiments which show these metals in tailings are absorbed by Imperata Cylindrical. But reducible-Mn significantly decreased after pot experiments. Based on experimental results, all metals studied in rhizosphere-influenced tailings are more stable than bulk tailings which indicate that the ecological risks of trace metalsdecrease after the phytoremediation of Imperata Cylindrical.

The authors raise a question of the necessity of urgent introduction of the principles of green building design into the practice. It is emphasized that such a necessity is dictated by the dangerous degradation processes occurring in the biosphere and society. In the given report the questions of social purpose and function of architectural activity are raised, as well as of the development of the sociology of architecture as an essential field of scientific research for providing the quality of design solutions.Green building technologies are widely spread in Europe, USA and in the Korea, China. Green building and sustainable building technologies have converted into a regular construction and building operation practice, whose mission is to reduce consumption of power and other material resources and to preserve or improve the quality of buildings and their comfort. The most reputable green building standards include LEED in the USA and BREAM in Great Britain. A discussion of local green standards, that will take account of the climate, landscape, and the lifestyle of residents, is underway in Russia. Principles of the ecologically sustainable design are being introduced into the architectural practice.

Eco-Industrial Park (EIP) is one of the most important practice forms of industrial ecology theory. Since the late 1990s EIP was introduced to China, many traditional industrial parks got down to construct EIPs. Represented by the National Eco-industrial Demonstration Parks (NEDPs), there were 85 parks passed the review of NEDPs construction planning, and 26 parks were named by NEDPs. In developing of the EIPs in China, there was still lack of clear and accurate understanding of the concept and connotation of EIPs. Based on the summary and analysis of the representative EIP definitions by domestic and foreign scholars, in combination with the practical situation of the industrial structure adjustment and industrial park development in China, this study put forward the three main points of EIP connotation. That meant that the coordinate development of the second industry and third industry; the construction of eco-industrial chain; the coordination development of economy and environment.

Based on the connotation and characteristics on cross coupling of industrialization and eco-environmental, the paper constructed the index system and measurement model on the coupling correlation evaluation of regional industrialization process and eco-environmental quality. The temporal feature of coupling factors and coupling degree between industrialization and eco-environmental in Inner Mongolia during 1990 to 2010 were analyzed. The results show: (1) The correlation degree of industrialization and eco-environmental in Inner Mongolia is between moderate to extremely close relationship, it shows that there is stronger coupling between industrialization and eco-environmental. (2) Environmental improvement and ecological protection are the main driving forces to promote the eco-environmental quality, industrial economy development is the stress factors for eco-environmental in Inner Mongolia. The feedback of eco-environment on industrialization is mainly on the support, restraint and limit function which the resource, environment, economy, science and technology factors on industrialization. (3) The coupling degree between industrialization and eco-environmental in Inner Mongolia has a fluctuation and stage feature. The coupling relation between industrialization and eco-environmental lies between the antagonistic period to running in stage.

This paper presents an overview of various innovative fabrication approaches and the potential applications of ionic polymer metal composites (IPMC), which is a composite material consisting of a polymer membrane sandwiched between two thin electrode layers. When given a voltage within a range of 1-5V, cations inside accompanying with water molecules of IPMC move across the width of the material causing a uniform water distribution and finally to achieve it’s bending motion. In addition to a classical processing method, three innovative modification approaches are recommended to fabricate IPMC, particularly to settle water electrolysis and leakage for multiple practical applications. Also, three applications are extensively highlighted in the later pages of the paper. This is a very new field and with the research done so far, it is believed that IPMC has a potential which is worth research elaborately. This paper presents an overview of the manufacturing components, techniques, related problems and applications of IPMC. Additionally, it recommends innovative modification fabrication approaches to subdue the associated problems in the existing conventional fabrication processing.

Published: March 2015

Unsteady magneto hydrodynamic (MHD) free convection flow of a viscous, incompressible and electrically conducting, well known non-Newtonian fluid named as Kuvshinski fluid past an infinite vertical porous plate in the presence of homogeneous chemical reaction, radiation absorption and heat source/sink is studied analytically. The plate is assumed to move with a constant velocity in the direction of fluid flow. A magnetic field of uniform strength is applied perpendicular to the plate, which absorbs the fluid with a suction that varies with time. The dimensionless governing equations are solved analytically using two terms harmonic and non-harmonic functions. The expressions for the fields of velocity, temperature and concentration are obtained. With the aid of these the expressions for skin friction, Nusselt number and Sherwood number are derived. The effects of various physical parameters on the flow quantities are studied through graphs and tables. For the validity, we have checked our results with previously published work and found in good agreement. Velocity decreases for an increase in visco elastic parameter α2, heat absorption coefficient φ, the chemical reaction parameter γ , the magnetic field parameter M, the Prandtl number Pr, the Schmidt number Sc, and increases for increase in Grashof number Gm, the radiation absorption parameter Q1
