The proceedings contain 63 papers. The topics discussed include: cylindric filaments and velocity structure functions;universal equations and constants of turbulent motion;the vortex sheet model for a turbulent mixing layer;joint statistics and conditional mean strain rates of streamline segments;variable-viscosity mixing in the very near field of a round jet;decomposition of the turbulent kinetic energy field into regions of compressive and extensive strain;non-equilibrium processes in non-homogeneous fluids under the action of external forces;on the Karman constant in turbulent channel flow;compressibility effects in Rayleigh-Taylor flows: influence of the stratification;surface dynamics in LES of full-depth Langmuir circulation in shallow water;large plasma filaments and geomagnetic field fluctuations excited concomitantly by solar powered microwave transmissions;and a search for the dominant free surface-fluctuation frequency downstream of the oscillating hydraulic jump with the Bayesian spectral density approach.

With the large-scale development of city underground space, all kinds of unexpected events in underground space have broken out in a rising trend. By analyzing the disaster-causing mechanism of city underground space emergencies, the vulnerability of city underground space and the early warning management mechanism of city underground space emergencies, this paper establish a risk management system of city underground space based on emergency to realize the harmonious development of city underground space.
In this research, we investigate an optimal method of commercial DBMS for analyzing large-scale web access log. Also, we develop the pre-processor in memory structure to improve performance and the user management too...

The effect of anxiety emotion on information processing of decision making was explored by computer stimulate experiment. The results showed that people with high anxiety used longer time to processing information than that with low anxiety. The depth of information search of low anxiety was more than that of high anxiety. Individual with high anxiety was inclined to use heuristic strategies, and Individual with low anxiety was inclined to adopt analysis strategies.

Rapid development in the field of smartphones over past years has enabled using their multimedia capabilities in virtually reconstructing and visualizing architectural objects by creating 3D-models of such objects. Several authors have tested cell phone cameras accuracy. For example Nokia N93, Sony Ericsson K750i, iPhone placed under test could be successfully used in applications not requiring ultimate precision [Gruen A, Akca D (2009) Evaluation of metric performance of mobile phone cameras. Institute of Geodesy and photogrammetry, ETH, Zurich. doi:10.3929/ethz-a-005749738;Takahashi Y, Chikatsu H (2009) 3D Modelling and visualization of cultural heritage using mobile phone cameras. In: Proceedings of the 3rd ISPRS international workshop 3D-ARCH, Trento]. Rapid technical development in the field of unmanned aerial vehicles (UAV) and lowering of their cost has made them available practically for everyone interested and eased tremendously use of such machines in aerial photography and photogrammetry [Eisenbeiss H (2009) UAV photogrammetry. Ph.D thesis, Dissertation ETH no. 18515, ETH Zurich;Remondino F, Barazzetti L, Nex F, Scaioni M, Sarazzi D (2011) UAV photogrammetry for mapping and 3D . In: Proceedings of the internationalconference on unmanned aerial vehicle in geomatics (UAV-g), Zurich]. We used Nokia N8 smartphone in our study since it had best optical, computing and communications capabilities at the time of this writing. In present paper we illustrate two ways of using smartphone's camera in mapping object's properties. One is a well known method of photogrammetric 3D-modelling. Another is a less used method of photogrammetric positioning [Dillon MJ, Bono RW, Brown D. L (2004) Use of photogrammetry for sensor location and orientation. IMAC-XXII: conference and exposition on structural dynamics, Jacksonville;Mautz R, Tilch S (2011) Survey of optical indoor positioning systems.

With the development of flexible HVDC technology in the world, back-to-back HVDC system based on MMC topology have more attention. A high power back-to-back flexible HVDC prototype has been developed to assess performance and reliability of construction of converter valve segment. Valve normal working condition(rated conditions rated voltage, current, temperature), valve transient working condition(temporary overvoltage, overcurrent), valve fault protection and anti-interference ability are accessed. Performance and reliability of control and protection equipment are assessed. The design of control and protection strategy is optimized. The correctness of main circuit design is tested.

Creating comfortable interior microclimate environment with comparatively lower energy consumption is one of the basic aims in building design. Combined with the comprehensive retrofit design practice of Wuhan construction building, the thesis investigates a set of practical building climatic design method which is based on computer simulation and analysis technology. Meanwhile, this article analyses the climatic design strategies of Wuhan construction building, and provides a references for architects in the conceptual design stage in the future.

In this paper, we focus on the problem of how to study ground fissure hazards in 3D way, and establish the 3D model of ground fissure. We mainly solve the expression of spatial distribution characteristics and principle of ground fissure in the digital environment. Projection-Deviation method is adopted to establish the 3D model of an arbitrary ground fissure with an inclination angle according to the actual situation. This method has been verified in Xi'an area, the satisfactory results have been obtained. The research achievement provides a new development tendency for studying around fissure hazards.
