Two concepts, multi agent system architecture and multi agent system architecture prototype are brought forward, and the method of descrbing the relation between agents using the concepts is explored. The structure and components are designed. Based on the fact that cooperation between distributed agents is erratic, a controlled natural language communication function is designed and realized. Applying the offered interfaces, the user′s workload consumed in agent communication and management is reduced, and at the same time, robustness of the multi agent system is improved.展开更多

The current state of BF ironmaking in Europe, America, Japan, and China were briefly overviewed. Moreover, some innovative BF ironmaking technologies aiming at environmental harmony and operation intellectualization in the world, such as waste gas recycling sintering, BF op eration with coke oven gas injection, ferro coke, lime coating coke, BF visualization and intellectuali zation, were roundly summarized. Finally, some discussion on the technologies was carried out and the development trends of BF ironmaking were pointed out. The review could provide references and supports for the progress of environment friendly technologies of BF ironmaking, thereby promoting their practical applications and achieving sustainable development of BF ironmaking, especially for Chinese ironmaking industry.展开更多

The motivation of the paper is to create a speech based Integrated Development Environment (IDE) for C program. This paper proposes a technique to facilitate the visually impaired people or the person with arm injuries with excellent programming skills that can code the C program through voice input. The proposed system accepts the C program as voice input and produces compiled C program as output. The user should utter each line of the C program through voice input. First the voice input is recognized as text. The recognized text will be converted into C program by using syntactic constructs of the C language. After conversion, C program will be fetched as input to the IDE. Furthermore, the IDE commands like open, save, close, compile, run are also given through voice input only. If any error occurs during the compilation process, the error is corrected through voice input only. The errors can be corrected by specifying the line number through voice input. Performance of the speech recognition system is analyzed by varying the vocabulary size as well as number of mixture components in HMM.展开更多

It means not only economic growth butalso changes towards a better direction in economic structure , social structure , relation between human soci-ety and environment, and even political structure. Present development should not damage the environmentbut leave the same or an improved natural resource endowment as a bequest to the future. This is the devel-opment with environmental sustainability. In this paper the characteristics of rural development were reex-amined, and what environmental sustainability means and how to measure it were explicitly presented. Prac-tical approaches for achieving environmental sustainability were also given with some cases from China.展开更多

Solid Waste and/or waste in general is an artefact of human activities that can spring from individuals, families, community, commercial/industrial operations etc. This study is a qualitative investigation, and it is intended to gather an inclusive knowledge of solid wastes management for better public health in Freetown, the Capital City of Sierra Leone. Statistical analysis was employed to observe numerical representations on a wide range of selected data. In an attempt to achieve the aim of this research project, reviews of available online resources were exploited, and juxtaposed with everyday knowledge in the existing state of the Freetown’s municipality solid waste management. The study revealed that residents in Freetown produce an average 0.45 kg of solid waste per individual per day. It was further established that biodegradable/organic matters comprise approximately 75% to 85% of total waste stream along with assorted retired furniture, scarp metals and plastic bags as most important recyclable elements. The hitches connected with municipal solid waste management in Freetown have become palpable, spanning from the past decade to date. Among many other factors, an upsurge influx urbanisation after the 11 years brutal civil war that ended in 2001, combine up with insufficient approved dumping sites for waste disposal and institutional incapability stand out. In this project, the contemporary approach of solid waste disposal in Freetown was carefully assessed with efforts to bring out the most feasible alternatives of solid waste disposal and acclaim ways of refining its activities. It was concluded from the study that, solid wastes in the Freetown Municipality must be tackled in a synergetic approach. That is, government corroborating with private solid waste managing actors so as to enhance an excellent better-public health, sustainable environmental, urban economic development and a resourceful energy paradigm.展开更多

In total, 139 monozygotic and 95 dizygotictwin pairs aged from 5 to 18 years were recruited.The twin correlations of total hand and wrist scoresfor monozygotic （MZ） and dizygotic （DZ） twins were0.71 and 0.36, respectively. Bivariate modelanalysis showed moderate genetic correlations onlyfor total skeletal maturity vs. weight and totalskeletal maturity vs. waist circumference （r, 0.51and 0.46, respectively）. Our findings demonstratedthat genetic factors played important roles in bonedevelopment of the hand and wrist in Chineseyoung twins, and that these genetic effects mightbe distinct from those influencing anthropometricmeasures.展开更多
