A geographic information system-based (GIS) method for estimating the lengthslope (LS) factor of the Revised Universal Soil Loss Equation using national-scale datasets was developed and validated. The method was applied to approximately two-thirds of the Mississippi River basin, focusing on agricultural subwatersheds in the Midwest. The results were validated by comparing the GIS-based statisti...

We describe the application of three-dimensional (3D) scattering interferometric (iSCAT) imaging to the measurement of spatial interaction potentials for nano-objects in solution. We study electrostatically trapped gold particles in a nanofluidic device and present details on axial particle localization in the presence of a strongly reflecting interface. Our results demonstrate high-speed (~kHz...

The evaluation of land quality plays an important role in the study of land resources. Some software of GIS was applied to evaluate land quality in recent years. There is some limitation in Appling GIS to evaluate land quality directly. GIS combined with MCE (Multi-Criteria Evaluation) can eliminate limitation existing in using GIS singly. In this thesis key technology of evaluating land qualit...

Hydropower is one of the major and sustainable energy production centers across world. Energy has several challenges uncertainty to alleviate poverty in our country. The main aim this study was selecteding hydropower potentials Temcha watershed with integrated approaches using GIS hydrological models (SWAT). For potential selection, it used weather (metrological), geospatial data. result shows ...

We review urban models useful in transportation planning, focusing especially on ones that are based on geographic information systems (GIS) software. We then describe UPlan, a simple model written by us in the ArcView GIS. Several different applications of UPlan are outlined, involving transportation planning and the analysis of the growthinducing effects of new facilitites, to demonstrate its...

GIS technology is credited with substantially improving police crime analysis and related resource allocation. Although GIS has been said to be an efficient and effective technology in policing, limited empirical assessment has been conducted. An examination of functions and a review of the literature suggests four major applications of GIS in policing: computerized crime mapping/crime analysis...

Sustainable bioenergy systems are, by definition, embedded in social, economic, and environmental contexts and depend on support of many stakeholders with different perspectives. The resulting complexity constitutes a major barrier to the implementation of bioenergy projects. The goal of this paper is to evaluate the potential of Multi Criteria Analysis (MCA) to facilitate the design and implem...

Background: Land use suitability assessment is a key factor in any urban and suburban planning and decision-making processes. The assessment is evaluated by a series of criteria involving socio-economic needs. To deal with the conflicting, disproportionate and multiple criteria, land usage will be characterized with respect to the preferences and importance. Meanwhile, many spatial decision pro...
