An effective approach was used to disperse CdSe quantum dots (QDs) into epoxy matrix and prepare highly transparent luminescent CdSe–epoxy nanocomposites. Dodecylamine-capped CdSe QDs were obtained through self-assembly of carbon chains of as-synthesized QDs and dodecylamine. It was found that dodecylamine-capped CdSe QDs demonstrate a homogeneous dispersion within epoxy matrix, thus the prepared CdSe–epoxy nanocomposites expressed transparence in the visible region and also light-emitting.

In this paper,the means of WiFi was used to access to mobile phone MAC address to get passenger flow data and existing prediction methods were compared. Then N6 of Chongqing International Expo Exhibition Center was taken as the object of study and 5min was taken as the time interval to count N6 hall passenger flow from 9:00 am to 17:00 pm of 5 open days to obtain time series. At last, ARMA model was established to predict passenger flow of short time. The results show that the mean we use in this paper has high accuracy of prediction, MAE is 2.8771,and the means can be used for the passenger flow prediction of exhibition well.

Introduced the system structure, working principle and diagnostic algorithm of a data acquisition and fault diagnostic system for diesel engines. The system is composed of a portable computer, a multi-channels data acquisition device and some sensors. Through behavior of the diesel and the characteristic values of signals, we can finish the non-disassemble examining and fault diagnosing. The structure and policy of the diagnostic expert system are also discussed.

Flue gas turbine is one of the highest failure rate of the power equipment in oil refinery now.It is a key role to achieve saving energy and reducing consumption, the goal ofpollution reduction and the safe, reliable and efficient operation of the flue turbine in refinery. Therefore, it is of great significance to the fault diagnosis of the blade by summarizing the fault reason of the flue gas turbine and using fault tree analysis.

The rapid development and expansion speed in the renewal of the China’s industrial cities are not suited to the current situations of large energy consumption of the existing buildings, these current situations causes the urban environment and resources to be destroyed and the sustainable development of cities to be severely hampered. To solve these problems, a variety of resources for urban renewal in the energy conservation reconstruction of the existing building should be deeply developed, such as analysis and research of reconstruction background, local natural environment and natural resources, utilization of waste and recyclable resources etc., at the same time, perfection of the existing building energy saving assessment system is also the key to promote the settlement of the problems. This paper demonstrates the energy conservation reconstruction and comprehensive utilization of the existing buildings in the industrial urban renewal in various aspects in order to promote the sustainable development objectives of the industrial urban renewal.

For the contradiction between the current urban public transport system and land use status in many small and medium-sized cities, the purpose of the paper is to present the counterplan framework of the land using mode and to provide mechanism and ensuring for the land using mode that matches the conventional public transit system.

The purpose of this paper is to experimentally and theoretically study the flexural behavior of concrete beams reinforced with fiber reinforced polymer (FRP) bars. In this research, two series of concrete beams reinforced with GFRP and CFRP were tested up to failure. Beam stiffness was the same for all beams until the appearance of first cracks. Deflection at failure was identical for beams reinforced with GFRP and CFRP bars, but force at failure of CFRP reinforced beams bars was greater. The theoretical analysis for calculating deflections was carried out. The theoretical results were compared to the test results for the simply supported beam deflections, and the theoretical predictions agree well with the test results.

Bionic tech. applied in the building skin is important to the researching and application of the architectural bionic. Building skin bionic technology is a burgeoning technology, which mainly relies on high-tech, new resources, ecological theory, and sustainable development theory. And, it’s aiming is to set up a harmony relationship between the architecture and the environment. Building skin bionic technology concretes used in the structure, material, form, and some other fields of the building skin; in the main, it researches the functions and effect, energy-saving measures, ecological balance, and some other technique regions of building skin in vivo. Bionic technology used in building skin is one of the most important orientations of future architectural development. This text focus on three aspects about the application of bionic technology in the structure, material, and form of building skin, to elaborate the application theory, instance, and prospects of bionic technology.

In this paper, Fe3O4magnetite nanoparticles decorated multi-walled carbon nanotubes (MWCNTs-Fe3O4) nanocomposite was successfully prepared. Firstly, carboxyl-functionalized MWCNTs were obtained after acid oxidization. Then, Fe3O4 nanoparticles were attached onto the surface of MWCNTs through chemical reaction between hydroxyl groups on the surface of Fe3O4 nanoparticles and carboxyl groups on the surface of MWCNTs.
