Several pervasive and mobile computing systems would benefit from being notified about special events happening in the city. In this paper we present a methodology to discover events from human mobility patterns as recorded by cell network usage. Experiments conducted over an extensive dataset from the main Italian telecom operator show that the proposed approach is effective and can be applied to...
China is the largest country to produce and consume Chinese medicine in world. People have come to realize that the side effects of chemical medicine gradually because serious pollution, ecological environment deterioration and human ‘lifestyle disease’ are among the most severe challenges with which human beings are faced today.

From our ethnographic studies on various kinds of museums, we discovered that guides routinely propose questions to visitors in order to draw their attention towards both his/her explanation and the exhibit. The guides' question sequences tend to begin with a pre-question which serves to not only monitor visitors' behavior and responses, but to also alert visitors that a primary question would follow...
This paper investigates the possibility of utilizing household generated biomass as a source of renewable energy to meet partial energy demand in the urban household in Bangladesh. The work proposes utilization of biogas generated by anaerobic digestion from urban waste using a small scale biogas digester. Three different systems that use biogas for operation, namely — gas operated light bulbs, gas...
Understanding collective mobility patterns is of great importance for various applications such as emergency detection, location based services and urban planning. As for existing researches, bank notes and mobile phone data are used for this goal. Here, we attempt to use traffic data to discover collective mobility patterns. A large number of sensors are distributed on the whole city roads to capture...
Cooperative design of complex artifacts always involves several specialists who necessarily have different technical cultures. Multi-agent systems mixing artificial and human agents are a key technology for supporting collaborative work. The paper first includes a brief description of such a supporting architecture, emphasizing the role of personal assistant agents. Personal assistant agents engage...
Human dynamics are inextricably intertwined with the social, geographical and economic environment. The continuous flux of people communicating as well as migrating, commuting, and traveling inevitably spans acquaintances across geographic space that is far from random and exhibits regular patterns. For instance, it has been shown that the probability of being acquainted with someone is closely related...
The unprecedented amount of data from mobile phones creates new possibilities to analyze various aspects of human behavior. Over the last few years, much effort has been devoted to studying the mobility patterns of humans. In this paper we will focus on unusually large gatherings of people, i.e. unusual social events. We introduce the methodology of detecting such social events in massive mobile phone...
In this work we use anonymous telecommunication data to investigate how migration influences the dynamics of mobile social networks. We analyze the evolution of social ties for an entire country over a period of 11 months, examining: tie strength, sociality level, distance of ties, and persistence of ties. We find changes in tie strengths pre and post migration, specifically at six months before and...
In recent 30 years, the ecological environment of streams suffers severe damage in Xintang town. Stream regulation is very important and urgent. Based on nature characteristic and existent problems, the paper uses data of water quality which were obtained in Oct., 2005, also remote sensing data from Google earth, and landform data from field measure to Study on urban stream regulation methods of Xintang...
Analysis and evaluation on land carrying capacity is the key content of environmental impact assessment of urban master planning, even an important criterion of determining the feasibility of resource and environment in urban planning. Currently, most cities are all facing the problem of land resource shortage, land carrying capacity has become the pivotal factor for restricting the urban development,...
Urbanization promotes the development of industrialization and information, and develops the economy rapidly. In recent years, China's urbanization accelerates. But, at the meantime the human settlement of urban residents has been seriously broken. At present, it is very important to coordinate the urbanization with human settlement development, and promote the urban human settlement sustainable development...
Urbanization is a necessary requirement and result for industrial development. The urban land intensive use is a natural way for urban development. Land use and urban development interacts. This paper selected the perspective of a reasonable quantitative evaluation of land intensive use and the comprehensive level of urbanization of Korla City, analyzing the relationship between the two systems. According...
On the basis of defining land use function conception and classification, this paper selects 12 indices from land use, environment and social-economic development conditions, and selects Analytical Hierarchy Process (AHP) method to identify land use functions distribution of Harbin-Daqing-Qiqihaer region in the northeast of China of the year 1976 and 2005 on geographical grid scale. Spatio-temporal...
As the founder of the theory of emergy, more and more scholars use the theory to quantitative analysis human nature, macro-regional environmental resources and the relationship between social and economic value, but for small environmental assessment is still relatively little study. As a study case, Chongqing green space system is analyzed. The results showed that: in 2009, the monetary value of...
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...
Objective To study the effect of chloride channel inhibitor NPPB(5-nitro-2-(3-phenyl-propylamino)-benzoic acid) on proliferation, cell cycle and apoptosis of human trabecular meshwork cells. Method Using MTT, flow cytometry, Annexin V-PI and mitochondrial membrane potential, we explored the role of NPPB with different centration (10μM, 50μM, 100μM) in cell proliferation, cell cycle, apoptosis and...
