The ancient aesthetics of yijing has played a crucial role in traditional Chinese philosophy, literature and art since the eighth century CE. Defined variously by early and contemporary writers, yijing links an artist’s emotional domain to objects in the world. This article conceptualises yijing as an ecological aesthetics and distinguishes it from an environmental aesthetics. In particular, two aspects of yijing render it an eco-aesthetics: subject–object correspondence (or ‘engagement’); and empathic identification with the environment (or ‘bio-empathy’). Three brief case studies from urban planning, environmental conservation and the creative arts demonstrate the contemporary importance of yijing to ecological issues. © 2017 The White Horse Press.

Based on the finite-time stability theory, this paper deals with finite-time synchronization for a class of fuzzy cellular neural networks with time-varying coefficients and proportional delays. Using differential inequality techniques and the analysis approach, we derive some new and useful sufficient conditions of finite-time synchronization for the addressed systems. Finally, an illustrative example with its numerical simulations is given to show the effectiveness of main results. © 2017 Elsevier B.V.

In this note, the controllability for a class of linear time varying impulsive systems with time delay in control input is studied. Sufficient and necessary conditions for the controllability of such systems are established. Specializing the obtained results to the cases of linear time-varying impulsive systems and linear time invariant impulsive systems with time delay, some simple criteria with respect to coefficient matrices, which are less conservative than some existing results are derived. It is also shown that the time delay in control input contributes to achieve the controllability of impulsive system even if the system is not controllable. Two examples are worked out to illustrate our results. © 2006 IEEE.

Crystalline γ-Al 2O 3 nanowires with diameter, 20.40 nm, length above 600 nm and aspect ratio above 30 have been successfully synthesized by thermal decomposition of boehmite (γ-AlOOH) precursors obtained via hydrothermal route by using AlCl 3, NaOH and NH 3 as starting materials. Thermogravimetric analysis (TG), differential thermal analysis (DTA), X-ray diffraction (XRD), transmission electron microscope (TEM), selected area electron diffraction (SAED) and high resolution transmission electron microscope (HRTEM) were used to characterize the features of the as-made γ -Al 2O 3 nanowires and their γ-AlOOH precursors. The pH value of the solution and the mixed precipitant play important roles in the formation of γ-AlOOH nanowires. After calcination at 500.C for 2 h, the orthorhombic γ-AlOOH transforms to cubic γ-Al 2O 3 and retains nanowire morphology. © Indian Academy of Sciences.

Purpose: The key control characteristics (KCCs) are very important to control dimensional quality of the final product. The purpose of this paper is to propose optimization algorithm and rules of design KCCs by optimizing KCCs of 2D and 3D workpieces based on equations and candidate locating points. Design/methodology/approach: This paper analyzes optimization process of 2D and 3D rectangle workpieces based on equations and candidate locating points by using fruit fly optimization algorithm (FOA). For decreasing variables of the algorithm, the improved fruit fly optimization algorithm (IFOA) is presented. Moreover, the Euclidean norm of inverse Jacobian is used as the objective function of optimizing KCCs by comparing different objective functions. Finally, a case of side frame assembly is presented to illustrate design and optimization of KCCs through IFOA, and results show that the method proposed in this paper is efficient and precise. Findings: The paper provides some reasonable conclusions for the design and optimization of KCCs. Originality/value: This paper designs and optimizes KCCs of fixtures and parts to improve dimensional quality of the final product. © Emerald Group Publishing Limited.

In free-form surface machining, the prediction of five-axis ball-end milling forces is quite a challenge due to difficulties of determining the underformed chip thickness and engaged cutting edge. Part and tool deflections under high cutting forces may result in poor part quality. To solve these concerns, this paper presents process modeling and optimization method for five-axis milling based on tool motion analysis. The method selected for geometric stock modeling is the dexel approach, and the extracted cutter workpiece engagements are used as input to a force prediction. The cutter entry-exit angles and depth of cuts are found and used to calculate the instantaneous cutting forces. The process is optimized by varying the feed as the tool-workpiece engagements vary along the toolpath, and the unified model provides a powerful tool for analyzing five-axis milling. The new feedrate profiles are shown to considerably reduce the machining time while avoiding process faults. © 2011 Springer-Verlag London Limited.

According to Mallat multi-resolution analysis, A new edge detection algorithm based on multiscale product is presented, which uses Gaussian function and its first-derivative as lowpass and highpass filter to enhance edge and suppress noise, then detect edge embedded noise by gradient direction and updating search method. The experiments show that this approach has advantages of detecting edge in different gray contrast, high signal-noise ratio and pixel-level location accuracy. © 2011 Published by Elsevier Ltd.

MMT had been used widely as an antiknock additive in petrol. It can enhancing the vehicles dynamic performance and reduces fuel consumption, but causes some negative impact on vehicle emissions. In this paper, the author research on the emission performance of a vehicle which meet Stage IV emission standard use gasoline containing MMT run for 50,000km.The test results show emission pollution such as CO, HC and NOx increased by MMT which result in three-way catalytic converter deterioration quickly. MMT also made the oxygen sensor deterioration and cause high NOx emission. © (2012) Trans Tech Publications, Switzerland.

Dissimilar welding between cemented carbide and invar alloy was carried out using CO2 laser beam and argon arc as heat sources η Phase was formed near WC-Co/weld interface and precipitations in the fracture were discovered. In order to disclose the microstructure and mechanical property, firstly, η phase's morphology and composition at interface were investigated using backscattered electron imaging (BEI); and element diffusion across heat affected zone near WC-Co/weld interface was further studied. Secondly, bend strength values of butt joint with different welding parameters were tested by four-point bend strength experiment. Finally, WC migration mechanism was further discussed and the bend strength was measured. The results showed: (1) microstructures consisted of columnar crystals, cellular crystals, eutectic structure and fir-tree crystal and dendritic crystals. The columnar crystals were surrounded by lots of fir-tree crystals. (2) WC migration was driven by stirring effects of welds, high pressure of molten materials and ionized shielding gas, interface reaction and surface tension. (3) η Phases dispersion did not decrease bend strength of butt joint. And the maximum bend strength was 1493.56MPa, which was attributed to NbC precipitations featured with super-fine fir-tree. © 2010 Elsevier Ltd.
