Biological NanoArchitecture: Architecture in the Age of Biomaterials
Authors: Elsamny Maged
Published: March 2013

Biological NanoArchitecture is to build natural spaces that contribute to the biological-system and integrated with the surrounding environment, and as healthy as the womb for an embryo to grow. It should have a positive effect on the health of its occupants while enriching the ecosystem of the planet by consuming zero resources and producing zero waste. In this paper, I will try to introduce the myriad potentials of advanced technologies in the 21st century to architects and builders. Advances in Biotechnology and Nanotechnology will change the way we think, design and construct our buildings, and transform our inorganic buildings into synthetic organic structures that can behave like living species and merge with the biological cycle of the planet. This change of thinking can be achieved through adopting bionic systems in our buildings and mimicking nature the way it builds life forms. After 3.8 million years of evolution, it’s nature that does it best to adapt for survival, and the more our buildings look and function like natural systems, the more we are likely to find solutions to our contemporary global problems like overpopulation and climate change. This requires that we should look at nature as a source of learning and inspiration rather than a source of materials and energy.

Kaiping Village Planning Thoughts during the Late Qing-Dynasty and the Republican Period (1900 -1949)
Authors: Selia Jin Hua Tan
Published: March 2013

Located in mid-southern part of Guangdong Province and southwest of the Pearl River Delta, Kaiping County stretches over an area of 1,659 sq. km. It comprises more than 2,700 villages, with a total population of 0.68 million. There are also 0.75 million Kaiping people residing abroad in 67 countries and regions (including Hong Kong, Macao and Taiwan). Kaiping people started to make a living abroad after the Opium War (1860), when China was forced to open their doors to the Western world. Most of them went overseas to North America, Latin America, Southeast Asia, Australia and New Zealand. Those people came back to their hometown area to build houses for their families during the later Qing Dynasty and the Republican Period (c.1900-1949). They combined new ideas with their traditional village planning principles when they established new villages. This article attempts to focus on local planning regulations and tries to explain how Western planning ideas were brought back and used in local village planning.

Authors: Monier Vincent , Bignon Jean Claude , Duchanois Gilles
Published: March 2013

This project deals with architecture and engineering involved in the process of architectur- al design. Based on native irregular components, it aims at developing an innovative approach in the conception and rationalization of non-standard structures. Contemporary architecture and its non- classical structures require the design of customized pieces. This process which is highly energy and resources consumptive does not always take into account the inherent material properties. This pro- ject develops a way of optimizing, in architectural structures, the use of native wood pieces that are not industrially transformed (e.g. boughs) or of reused pieces of carpentry. As a consequence, the ecological footprint of the structures would be reduced.

Published: March 2013

Sustainable development is the topic of the world development in the current, and it isn't also an exception for construction industry which is one of the pillar industries of the national economy. It will produce a series of environment problems during the operation process of construction industry, and result in great influence on human. Furthermore, cost management is an important research subject in the construction industry，and its purpose is also to pursue composite benefits. We should stand on the higher layer, the whole society and economy layer, and pay attention to the project’s impacts on society and environment to realize the total optimum profits of economy, society and environment. Researching cost management based on the strategy of sustainable development has important realistic meaning to the project itself and even the whole world.

Authors: Xue Xiao Nan , Song Wei Hong
Published: March 2013

This paper discuss the fire objective of commercial center integrating the shopping mall and Wal-Mart supermarket etc., and also the auxiliary engineering project of commercial and residential buildings composed by high-rise residential areas. "Fuel Island" design method is adopted to prevent the radiation and spread across functional areas including dining area and commercial area. The maximum heat release rate of fires at various scenes is also determined by different approaches, and then the larger value is taken as the final fire scale.

The construction project bidding is a feasible method in engineering transactions and the main competition form of the construction activities under the conditions of the market economy. The bid assessment is an important link of bidding, and whether bid evaluation method is scientific or not, is directly related to the success of the tender. In the engineering construction field, at present the current commonly used evaluation methods are the comprehensive evaluation method and the lowest bidding price evaluation method. Based on fuzzy set theory and multi-objective people decision theory, we introduce fuzzy multi-objective people decision-making evaluation methods. And conducting research to put forward the evaluation index and weight method to determine the bidding decision model. Finally we apply it to actual case to make out the more standardized and scientific bidding evaluation method.
The Application of Multifractal Theory and LVQ Neural Network in Maize Disease Intelligent Identification
Authors: Xia Zheng Wei , Wang Fu Juan
Published: March 2013

In this paper, according to the different maize disease images having different shape features，eight multi-fractal spectrum values were extracted as shape characteristic parameters of maize diseases, and then they were used to index on image data base. We applied learning vector quantization（LVQ）neural network to simple training，classfication and recognition. The method for recognition of maize disease can reach a higher recognition rate.

Authors: Zhang Ying Gui , Lei Ding You , Zeng Qiong Fang
Published: March 2013

Railway out-of-gauge and enhanced-load goods (ROEG) transport organization with risky, costly and difficult characteristics is the system engineering. For better scientific online management, ROEG dispatching system (ROEGDS) with B/S mode and three-layer is developed. Then, with the network framework and architecture for ROEGDS, network security technologies including firewall intrusion detection, dynamic password authentication, security vulnerability assessment technologies and so on are all put forward. Besides, concrete security management measures are further given from four aspects to ensure network security. The results from its trial in Nanning Railway Administration show that ROEGDS can achieve given goals and these network security technologies and management measures put forward in the paper can also guarantee ROEGDS and ROEG transport safety.

Published: March 2013

Realistic modeling and deformation of soft tissue is one of the key technologies of virtual surgery simulation which is a challenging research field that stimulates the development of new clinical applications such as the virtual surgery simulator. In this paper we adopt the linear FEM (Finite Element Method) and sparse matrix compression stored in CSR (Compressed Sparse Row) format that enables fast modeling and deformation of soft tissue on GPU hardware with NVIDIA’s CUSPARSE (Compute Unified Device Architecture Sparse Matrix) and CUBLAS (Compute Unified Device Architecture Basic Linear Algebra Subroutines) library. We focus on the CGS (Conjugate Gradient Solver) which is the mainly time-consuming part of FEM, and transplant it onto GPU with the two libraries mentioned above. The experimental results show that the accelerating method in this paper can achieve realistic and fast modeling and deformation simulation of soft tissue.
