Simulation and Impact Analysis of Flooding Caused by the Break of a Concrete-face Rockfill Dam by ZHAN Mingqiang, GUO Yurong, YANG Yanlong, CHEN Bo

“…Simulation and impact analysis of flooding caused by the break of water reservoir dams is a research priority in the field of prevention and mitigation of disasters surrounding water conservancy projects.To study the scope of submergence and the influencing degree in the downstream areas caused by the break of a concrete-face rockfill dam,by analyzing the characteristics of the concrete-face rockfill dam break,this paper built a one-dimensional unsteady hydrodynamic model of the area from the concrete-face rockfill dam to the hydroelectric power plant reservoir in the downstream.Then,with an actual concrete-face rockfill dam project as a research case,the flood flow distribution under various failure modes of the selected dam case was simulated.The peak flow rate,highest flood level,and the corresponding emergence time of typical sections along the watercourse under the dam were obtained.The results show that the dam-break duration,the final size of the breach,and the water level in front of the dam before the break are the three major factors influencing the simulation calculations with this hydrodynamic model.Shorter duration of dam break,a larger final size of the breach,and a higher water level in front of the dam before the break will lead to a larger peak flow at the dam site.Also,in various dam-break conditions,a large proportion of the major villages and towns on both sides of the downstream flow are expected to be completely submerged.These findings may offer reliable scientific references for the formulation of emergency response and rescue protocols as well as disaster severity evaluation associated with flooding caused by the break of presently active concrete-face rockfill dams.…”

Electronic Structure of Single-Wall Silicon Nanotubes and Silicon Nanoribbons: Helical Symmetry Treatment and Effect of Dimensionality by Pavol Baňacký, Jozef Noga, Vojtech Szöcs

“…The results obtained for nanotubes in wide diameter range of different helicity types have shown that metallics are only SWSiNTs with diameter up to <6.3 Å due to the effect of curvature, which induces coupling of σ and π orbitals. From the calculated band structure results that, irrespective of helicity, the SWSiNTs of larger diameter are small-gap semiconductors with direct gap between the Dirac-like cones of (π*,π) bands. …”

Social network user geolocating method based on weighted least squares by Wenqi SHI, Xiangyang LUO, Jiashan GUO

“…When providing location-based dating and other location-based services, social networks will confuse the displayed user distance text to protect the user’s location privacy.In order to verify whether the current location confusion mechanism adopted by social networks can effectively protect user’s accurate location, a social network user geolocating method based on weighted least squares was proposed.The method constructed real-world tests to collect a large number of confused distance texts in location dating service, and identified the real distance boundary of reported distance combined with real distance data.Then, based on the discrimination of the quadrant of the coordinate system where the target user was located, the position of probes was optimally deployed, and multiple preliminary position estimations of the target user were obtained by using the trilateration model.The weights of the longest and the shortest distance of the target user were determined by the estimated position, and the related objective function was constructed.The optimal solution of the objective function was calculated based on the weighted least squares, which was the final geolocating result of the target user.The proposed method inferred the location of social network user based on the distance boundary constraint, which avoided the frequent query of location services and ensured the geolocating efficiency.The actual geolocating results based on 500 WeChat users showed that, the proposed method can accurately geolocate the “eople nearby” users of WeChat.Compared with the existing typical geolocating methods based on space partition and heuristic number theory, the proposed method have better performance in geolocating accuracy and efficiency.The average geolocating error is reduced by more than 10%, and the number of location service quarries in the geolocating process is reduced by more than 50%.…”
