Authors: Jiang You Bao , Liao Guo Yu
Published: October 2012

Parametric analysis of ultimate loading capacity is performed by the finite element method considering the dual non-linear effects for inner concave cable-arch structure with different arch rise-span ratio. The results show that for the inner concave cable-arch structure with other given conditions, the failure loads of the steel arch and the cable increase with the increase arch rise-span ratio, but the increasing ratios are different. The failure modes of inner concave cable-arch structure may be divided into three types: the steel arch failure, the overall failure and the cable failure. According to the considered parameters range in this paper, the steel arch failure mode may occur when the arch rise-span ratio is less than 0.3; the overall failure mode may occur when the arch rise-span ratio is between 0.3 to 0.35; and the cable failure mode may occur when the arch rise-span ratio is greater than 0.35. This provides some useful references for rational design of such structures.

Authors: Zhang Ming Liang , Zhao Ting Yao , Xia Hai Nan
Published: October 2012

An implicit finite volume scheme is developed to solve the depth-averaged 2-D shallow water flow equations. The computational mesh consists of rectangular cells, with quadtree technology incorporated to locally refine the mesh around structures of interest or where the topography and/or flow properties change sharply. The governing equations are solved using the SIMPLEC algorithm on non-staggered grid to handle the coupling of water level and velocity. The discretized algebraic equations are solved iteratively using the GMRES method. The model has been tested against measurement data for steady flow at T Junction channel, unsteady flow in idealized estuary, tidal flows and pollutant transport in Gironde Estuary. The model reasonably well reproduces the temporal and spatial variations of water level and current speed observed in the measurements.

Measurement and Evaluation for Productivity in Extreme Hot Environment
Authors: Sun Yu Ping , Zhu Neng , Tian Zhe
Published: October 2012

The productivity in extreme hot environment is not only influenced by the complexity of the task and the technical proficiency of the workers, but also closely related to the heat stress caused by the hot environment. In this study, three methods of productivity measurement were introduced, mainly referred to their applications and limitations. The method of using thermal sensation vote was based on the subjective feelings, and its application was convenient. The method of using wet-bulb globe temperature was based on the environment parameters and working time. It can be applied to a wide range of high temperature. While the method of using predicted mean vote had more comprehensive considerations of environment parameters and thermal sensation, but the complexity measurement of the environment parameters limited the usefulness of this method. Different from the three methods, this study proposed the physiological stress index to be the argument in the calculation of productivity. The physiological stress index combines both the environmental intensity and labor intensity. It reflects physiological conditions of the workers directly and has the potential to predict the productivity online.

Authors: Wu Xiao Na , Wang Liang , Zhang Zhao Hui , Li Wen Yang , Guo Xing Fei
Published: October 2012

Carbon dioxide (CO2) absorption performance from flue gas was investigated using monoethanolamine (MEA) solution in porous hydrophobic polyvinylidene fluoride (PVDF) hollow fiber membranes contactor. The influence of operating parameters on CO2 removal efficiency and flux were studied in the immersion operating mode. The experimental results indicated that the CO2 removal efficiency and flux decreased with the increase of flue gas load and carbonization degrees, but the increase of the absorbent concentration and temperature promoted membrane performance of CO2 capture. An increase of 84 m3•m-2•h-1 in the flue gas load resulted in a 68% decrease in the removal efficiency. Absorbent carbonation degree increased to 0.45 mol CO2•mol-1MEA led to the decrease of active ingredient amounts in the absorption solution, and the corresponding removal efficiency and membrane flux dropped by 50% of the initial amounts, respectively. The increase of concentration and temperature of absorbent also benefited membrane absorption performance of CO2 absorption, so that the concentration and temperature of the solvent increased lead to the CO2 removal efficiency and flux increased.

A New Algorithm for Optimal Parameter Settings of Light-Gauge Steel Wall Sound Isolation Systems
Authors: Lee Chao Tsung , Kuo Hsin Chuan , Liou Der Yuan
Published: October 2012

A new algorithm based on orthogonal arrays is developed to determine the optimal solution among the optional settings using the design of experiment approach for newly designed devices. The proposed algorithm begins with several successive orthogonal arrays and ends with a full factorial array. In the proposed algorithm, we suggest a mandatory verification of two additional settings at each orthogonal array to avoid errors in identifying the best level of the dominant factor, which often occur when a non-separable problem is solved. We initially verify the proposed algorithm by applying it to a well-known benchmark problem, the Rosenbrock function. The proposed procedure is described in detail in this paper. To distinguish the superior performance of the proposed algorithm relative to that of other design of experiment approaches, we study three types of problems with non-interactive or interactive variables. Finally, a light-gauge steel wall sound isolation system design is used to demonstrate the robust performance of the proposed algorithm. The results show that the proposed method not only provides a final solution that is identical to the problem’s exact solution but also requires much less computation time than a full factorial method.

Published: October 2012

Adsorption and desorption kinetics is critical in the efficiency and performance evaluation of the adsorbents. In this study, the adsorption and desorption kinetics of copper and/or zinc ions was investigated with the polyamine-functionalized adsorbents (P-TETA). The adsorption kinetics was studied in both single species system (when only one metal ion was present) and binary species system (when both metal ions were present). The adsorption kinetics in single species system was well fitted with two models at two stages for both Cu and Zn ions, indicating that the adsorption was diffusion-controlled at the initial stage and attachment-controlled at later stage. The adsorption kinetics in binary species system revealed the stronger coordination affinity of Cu ion with P-TETA than Zn ion. The desorption kinetics was well fitted with Elovich model for Cu ion desorption only, in both single and binary species system, with a higher desorption rate in single species system.

Global stone trade is mainly based on its practical function, therefore its added value is relatively low and the price competition is also very fierce. In fact, due to the inherent characteristics of stone, its added value can be greatly increased by extending its functionality through creative design. Brand marketing based on creative design can also expand its sales territory and sales volume. This paper discusses the methodology of creative design for stone products and some relative interdisciplinary theories, elaborates the enormous market potential of stone products by some examples of creative design.
On Important Role of the View of Harmony between Man and Nature in Modern Art Designing - Taking Environmental Design as an Example
Authors: Lv Gang
Published: October 2012

This paper mainly discusses the important role of the Chinese ancient view –“harmony between man and nature” in modern design. It focuses on the analysis of popular concepts of “environment orientation” and “people orientation” in environmental design, and holds the view that the concept of “harmony of man and nature” makes up for the deficiencies of the first two. In dealing with the relationship between man and himself or nature, the concept of “harmony between man and nature” offers a good theoretical basis which will surely become new ethics and standard in design.

With respect to the higher sound insulation need of the buildings, the attached room may be considered to adopt. A calculation model is applied to predict the sound insulation of a specified attached room. Realistic sound insulation inversion, furthermore, is consistent with the procedure of engineering practice. By the artificial immune algorithm (AIA), the inverse sound insulation prediction model is developed, which adjust the insulation of each element (wall, door and window etc.) and sound absorption of the attached room. Under agreeing with the reasonable configuration of an attached building and meeting sound insulation requirement simultaneously, it was found that acoustic properties of each member within a whole attached room were obtained. As a consequence, the material and even the configuration of each wall can also be determined. It will be beneficial to building design.
Indoor Thermal Environments Investigation in Winter of Rural Houses in Yinchuan
Authors: He Quan , Liu Da Long , Zhang Qun
Published: October 2012

The main considerations of building some new-type rural houses in Yinchuan are to improve indoor thermal environment and to reduce heating energy consumption by passive solar use and high-insulation envelope. Two houses were measured, a traditional one with adobe walls and a wooden roof, and a newly-built one with straw-bale insulation. Results show: (1) the linear layout of the traditional house leads to a higher heating energy consumption than the new one with climatic buffers; (2) the new house with straw-bale bricks have better thermal insulation performance than the traditional one with adobe wall; (3) lacking thermal storage is one of the main causes of larger indoor temperature fluctuation in the new house; (4) as a traditional partial interval heating mode, the “Kang”(a bed-stove made of bricks or fired clay) in the bedroom uses energy efficiently and improves the indoor thermal comfort.

Abstract: this paper starts the research with comparison and analysis for correlative conceptions in the field of architecture landscape. For the most important and active sight element –- non-level sight element, the author reasoningly clarifies them according to the conceptions of architecture interface. This paper analyses and diagrammatizes the sight characteristic of vertical interface of architecture landscape and people’s activity characteristic in the architecture landscape space defined by vertical interface, and regards them as formal language between people and environment. Then the paper begins a discussion for the issues of vertical interface of architecture. This analysis based on the theory of building typology, and starts from investigating for instances.
The Creation of Complexity in Chinese Garden
Authors: Dai Xiao Ling , Luo Chang Hai , Chen Xiao Jun
Published: October 2012

Chinese garden was designed to allow its owner to feel the beauty of nature in a congested city. Therefore, one of its main design principles is to make the space feel bigger than its real size, in other words, the creation of complexity. Former studies of traditional Chinese garden were mostly qualitative analysis. This paper applied the space syntax approach to study its spatial design. Two gardens (Guo’s Villa in Hangzhou and Lion Grove Garden in Suzhou) with similar sizes were selected as comparative case studies. To analyze the effect of spatial complexity to human’s behavior and cognition, movement tracing and questionnaire were used to collect behavioral and cognitive data. To analyze the spatial complexity in two gardens quantitatively, VGA analysis in the Depthmap software was used. By putting the spatial attributes of the gardens and the visitors’ activities in them together, the authors find out that: firstly, by different ways of partition and composition, sites with similar size could result to dissimilar feelings; secondly, create a mismatched system of walkability and visibility is an effective way for the creation of complexity.
