The necessity and inevitability of saving and intensive land use is decided by the conditions of more people and less land in China. China is a mining country and there are large numbers of abandoned land caused by mining. Therefore, the saving and intensive reuse of abandoned mine land should be an important component of saving and intensive land use. Based on the analysis of present status of China's...
The development and evolution of town met the demand for their own physical space structure, activity and space growth. The landscape spatial form of town with Chinese characteristics shaped place special spatial structure of the ancient townscape. Although the development of all town could not be separated from shaping physical spatial and people's activities, about it also continues to grow and...
A direct thrust allocation algorithm based on the searching of the optimal feasible cone is proposed to reduce the online computation load. The algorithm first concentrates on finding an optimal feasible cone for the unconstrained allocation problem. Then, constraints are taken into account to select out the target thruster and compute the corresponding control contribution. Control error is thus...
In this paper, we establish the nonlinear dynamic model of wind turbine gear train, which contains one planetary gear set and two parallel axial gear set. The strongly nonlinear factors, including time variable mesh stiffness, nonlinear backlash and meshing error, are included in our model. To convert the semi-define system with rigid displacement model into define one, we introduce the relative meshing...
Recently, because of the blind spot of oversize vehicle, accident happened repeatedly when the vehicle turned right. Therefore, to solve the problem, an embedded system based on computer vision technology which can early warn driver is proposed. Capture image with CCD camera, extract the background by using background subtraction, and build background model by the way of weighted average. After that,...
Urban excellent modern architectures are outstanding historical and cultural heritages, the research of protecting them includes two important contents, which are identifying standards and protection management strategies. From these two aspects this paper analyzes the protection research backgrounds, objects, and status quos of the urban excellent modern architectures and establishes the research...
Biogas digester technology is an available method in mitigating energy crisis, dealing with global climate change and improving rural ecological environment. This paper study the development history, new trend and research hotpots of biogas technology of those countries in which biogas technology are well developed, contract different development models of these countries to reveal their qualities...
This paper introduces the basic theory, principles and study scope of construction bionics, discusses the significance of construction bionics on preserving the ecological environment and completing the scientific system, etc. Based on the developing history of construction bionics, carried out the classification for bionic design and analyzed the status of bionic design, and summed up the impact...
China is usually called as the etiquette nation, which has a long historical cultural tradition. Etiquette is an indispensable component of traditional culture, which played a huge role in the maintenance of social order, agglomerating the nation and the human hearts, adjusting interpersonal relationships. This paper summarized the basic characteristics of Chinese traditional etiquette and custom...
Xiangshan area as a source for China's modern business, it's business ideas had changed Chinese people's consumer attitudes, lifestyles and even China business development process. Based on the study of the ideological content of Xiangshan business ideas, this paper tried to investigate the relationship between Xiangshan business ideas and the urban construction of Modern Zhongshan City, as well as...
This paper is a study of P.R.C. modern architecture conservation regulation system and implementation strategy. In theory, the conservation of excellent modern architecture is mainly under three regulation systems, “Law of the People's Republic of China on the Protection of Cultural Relics”, “Ancient Cities, Towns and Villages Protection Regulations” and “the Guidance on the Strengthening Protection...
A method based on instantaneous wave number is proposed for structural damage detection, which is designated to describe the change of structural dynamic properties with time caused by damage. Based on the wave theory, the derivation of wave number is introduced first. Then, the method for modal parameter identification and instantaneous wave number calculation using time-varying vector autoregressive...
The site of Unit 731 is a historical evidence of Japanese Imperial Army cruelly kill China during World War II. It belongs to one of latter-day sites in Harbin. However, with the historical variance, the integral and original sites had destroyed, which leads to difficulties for preservation. A new design theory of “Recall history and Expect peace” that overlapping and splicing of the current landscape...
In the present research, the problem of controlling a ducted fan Unmanned Aerial Vehicle (UAV) for hovering flights is addressed. For this purpose, a short review of the mechanical characteristics of the vehicle and also its mathematical model is presented. Numerical simulations are used to illustrate the performance of the developed controllers in certain and uncertain conditions.
The Great Wall of Jin dynasty is a tight military defense system, relying on the integrity and systematic. It is more mature than the former. The structure of the Jin Great Wall is special designed for defending against nomadic cavalry, and some features inherited by the Great Wall of Ming dynasty.
The Great Wall of China demarcates the agricultural civilization and the nomadic civilization in the Chinese history, and also protects the agricultural nationalities as a defense in the north. The course of the Great Wall is determined by a variety of factors, including the climate change, one of the external causes. The analysis of global climate change indicates that meteorological fluctuation...
The solution of longitudinal wave of a column through vibration equation taken as an example, the vibration equation was proved to converge to wave equation when the discrete spatial size converges to be infinitesimal. Concept of calculation wave velocity was proposed. Wave's propagation could be seen in the vibration's solution obtained with central difference method when calculation wave velocity...
Thought is the forerunner of action in the new period, to improve college students' ideological and political education work for college students, as the implementation of ideological and political education is one of the main position will outline of modern Chinese teachers should be guided by the scientific development concept, properly, strengthen occupational role to the overall development of...
Digital museum has become an important mode in culture communication with the great development of information technology. At the same time, the digital museum depending on physical articles is restricted by communication subjects in terms of collection and integration of the original materials. Due to the fact, thematic digital museum mode is proposed based on the digital museum in this paper, which...
How did students react to Interactive Whiteboard in the Chinese background of exam-oriented education system? This study with mixed method was conducted to investigate the students' perception, exam performance and difficulties confronted in one Chinese secondary school after two months' using of IWB. It was found that students had positive perception, especially to art curricula and student studing...
