As one of the most important natural resources, groundwater is associated with the environment, public health, welfare, and long-term economic growth, which affects the daily activities of human beings. In modern urban areas, the primary contaminants of groundwater are artificial products, such as gasoline and diesel. To protect this important water resource, a series of efforts have been exerted, including enforcement and remedial actions. Each year, the TGPC （Texas Groundwater Protection Committee） in US publishes a ＂Joint Groundwater Monitoring and Contamination Report＂ to describe historic and new contamination cases in each county, which is an important data source for the design of prevention strategies. In this paper, a DDM （data dependent modeling） approach is proposed to predict county-level NCC （new contamination cases）. A case study with contamination information from Harris County in Texas was conducted to illustrate the modeling and prediction process with promising results. The one-step prediction error is 1.5%, while the two-step error is 12.1%. The established model can be used at the county-level, state-level, and even at the country-level. Besides, the prediction results could be a reference during decision-making processes.展开更多

With PCA and GRA employed, the driving forces have also been analyzed. The driving force of city welfare and social structure, the towing force of city industrial structure transition, and the pressing force of city construction and reconstruction are main momentum factors. Moreover, the latter forces are more significant.展开更多

The recent developmental urban processes have been considered through three groups of indicators： demographic, regional and socio-geographic development. Based on results of the surveys conducted in the regional economic centres in Bosnia and Herzegovina in 2011, a development of urban functions in the urban centres has been shown. It has been proved that the dominant tertiary activities have a big importance and an intensive influence on urban and economic development in all urban settlements. The research included a theoretical part within which the literature on urban and economic development of settlements has been searched. For needs of the research, eight economic centres in Bosnia and Herzegovina were chosen. Analysis of the obtained results shows a different level of urbanisation in Bosnia and Herzegovina with particularly separated larger and asymmetrically distributed urban centres： Sarajevo, Tuzla, Mostar, Banja Luka, Zenica, and Biha6. The mentioned urban and economic centres are distributed along the major traffic communications. The settlements in east and west part of Bosnia and Herzegovina, in which a traffic network is poorly developed, have a lower urbanisation level. The obtained data proved the existence of a traditional difference and a different level in development of particular regions and total economy in Bosnia and Herzegovina. Low urbanisation level of a large number of settlements in Bosnia and Herzegovina, is in direct connection with economic development and density of those settlements. The achieved urbanisation level with an overall economic development is characteristic of Bosnia and Herzegovina and of the other countries in its surroundings as well.展开更多

By using the Grounded Theory research method, which refers to Glaser and Strauss, phenomenological observations and Hermeneutic-lnterpretive method of Ricouer, the process of deriving quality form an architectural presence is revealed. By connecting the Spatial Archetype Theory of LobeU, the paper reveals the ＂inflated ego of the Ruler as Leader＂ was manifested by symbol rays of Radiant Axes civilization through Soekarno＇s unconsciousness thought of space. The presence of architecture the National Monument serves not merely as a city landmark, but more than that, it roles as the center of orientation and development for a Jakarta Master plan conceived 50 years ago and still maintained to this day as the basic of the Jakarta City Planning 2030 In effect, this means that the National Monument plays the role as the axis of Indonesia＇s modem civilization.展开更多

Samples of new activity and deformation were collected and oriented slices were ground based on the samples ' original state to make the micro structural analysis and demonstration. All of the above research shows very clear linear tectonic geomorphology along the fault,three trenches across the fault zone all revealed new deformation traces since late Quaternary. The latest stratum dislocated by the fault is the late Quaternary and Holocene. The main slip mode is stick slip,as represented typically by fault scarps,wedge accumulation,the faults and the filled cracks and so on. In general,it shows the characteristics of brittle high-speed deformation and belongs to the prehistoric earthquake ruins. The above understanding was confirmed partially by microscopic analysis. In addition,the similarities and differences and the possible reasons for the characteristics of the latest activities of the Tancheng-Lujiang fault zone in the north and south of the Huaihe River regions are also discussed in this paper.展开更多
