Critical junctures and city development: a brief retrospect of Chongqing’s planning history, 1949-2010

Southwest China’s Chongqing is a city with unique development history which experienced critical junctures. This study collected and organized political, economic and cultural events in Chongqing from 1949 to 2010, and then analysed how its city planning responded to those critical junctures, and evaluate whether it was successful or not; furthermore, it traced the evolution of motive forces in Chongqing. The analysis has led us to the conclusion that critical junctures constituted pivotal motive forces in Chongqing’s urbanization; generally, each version of Master Plans responded them effectively and timely, especially by giving the priority to natural geography and continually developing the polycentric structure at different scale. The result of this study shows that Chongqing has built a comprehensive development framework for settlement hierarchy structure, transportation, economy and ecology. For the future, it should pay more attention to improve its infrastructure, conserve its historic heritage, strengthen its identity as a city of mountain and river, and achieve more sustainable development both ecologically and socially. Moreover, besides making sure that politic and economic forces fulfil their role, decision makers should also value social forces, make multiple objectives, exercise public participation and achieve social justice in the policy making and implementing process

1,3-Dimethyl-1H-indole-2-carbonitrile

The title compound, C11H10N2, crystallizes with two mol­ecules in the asymmetric unit, both of which are essentially planar (r.m.s. deviations = 0.014 and 0.016 Å). In the crystal, aromatic π–π stacking inter­actions occur [shortest centroid–centroid separation = 3.5569 (11) Å]

Dynamical analysis of wind turbine blades based on harmonic response

As the forces applied on the wind turbine blade are irregular, the deformation and concentrated stress of the blade may vary with the load and excitation. And the lamination of composite materials is critical to blade design, it directly affects the performance and power of wind power plants. In this paper, the response characteristics of the wind turbine blade is analyzed by the application of the harmonic response method under different ply angles. Through the simulation results, the performance of the actual blade is estimated, and the rationality of this design is judged. The results demonstrate that the blade displacement response amplitude is the minimum when ply angle is 45°. It is also found that the maximum displacement response occurs in the Y direction (i.e. parallel to the flow direction) by analyzing the displacement of each section in the blade, while the maximum stress is located at blade root

Fast Parallel Exact Inference on Bayesian Networks: Poster

Bayesian networks (BNs) are attractive, because they are graphical and interpretable machine learning models. However, exact inference on BNs is time-consuming, especially for complex problems. To improve the efficiency, we propose a fast BN exact inference solution named Fast-BNI on multi-core CPUs. Fast-BNI enhances the efficiency of exact inference through hybrid parallelism that tightly integrates coarse- and fine-grained parallelism. We also propose techniques to further simplify the bottleneck operations of BN exact inference. Fast-BNI source code is freely available at https://github.com/jjiantong/FastBN

2-Eth­oxy-4-[2-(3-nitro­phen­yl)­hydrazono­meth­yl]phenol

The title Schiff base compound, C15H15N3O4, was prepared from a condensation reaction of 3-eth­oxy-4-hydroxy­benz­aldehyde and 3-nitro­phenyl­hydrazine. The mol­ecule is nearly planar; the dihedral angle between the hydroxy­benzene ring and the nitro­benzene ring is 6.57 (7)°. O—H⋯O, O—H⋯N and C—H⋯O hydrogen bonding helps to stabilize the crystal structure

CP Violation in γγ→t tˉ\gamma \gamma \to t~\bar{t} within the Minimal Supersymmetric Standard Model

The complete analysis of the CP violation in the process $\gamma \gamma \to t \bar{t}$ in frame of the Minimal Supersymmetric Model(MSSM) is presented. The CP-odd observables for describing the CP violating effects in polarized and unpolarized photon collisions, are calculated. We investigate the possible CP violation sources induced by the complex soft breaking parameters and study the CP violating effects contributed by gluino, neutralino and chargino sectors appearing in the loop diagrams. We find that it is possible to observe the CP violation effects in top quark pair production via polarized and unpolarized photon fusions by using optimal observables and favorable parameters.Comment: 15 pages, LaTex, including 14 figures in eps file
