T o effectively perform most software engineering tasks on an existing system, a software engineer must have some understanding of the system's source code. However, gaining insight into the source code of large and complex systems typically takes too long and costs too much. In an attempt to address this problem, we developed the software reflexion model technique, 1 which lets software engine...

The present study is about the analysis of mean, mean maximum and mean minimum temperatures carried out on annual, seasonal and monthly time-scales examining the data from 8 meteorological stations in Istanbul for the period 1975-2006. Various spatial and statistical tools were used to display and analyze trends in temperature data. ArcGIS was used to produce the spatially distributed temperatu...

To study crop recommendation fertilization of the rural farmers as the main in our country, the paper took towns and villages of Hua County as the study area, took recommendation fertilization of wheat, maize and peanut as the study object, designed model components of crop balance fertilization by using Object-Oriented technique, and developed the decision-making system about crop recommendati...

This paper describes TerraHidro that is a distributed hydrologic modeling platform. TerraHidro is general purpose water resources system that presents a new concept to represent water flows based on graph structure, in the geographic information system (GIS) context. The drainage extractions and Amazonian basin delimitations using TerraHidro have been compared with ArcGis Hydro Tools regarding ...

Microbial marine biodiscovery is a recent scientific endeavour developing at a time when information and other technologies are also undergoing great technical strides. Global visualisation of datasets is now becoming available to the world through powerful and readily available software such as Worldwind, ArcGIS Explorer and Google Earth. Overlaying custom information upon these tools is withi...

Geographic data, stored and processed in a GIS, form a conceptual model of the real world. The abstraction of the real world to construct the conceptual model unavoidably results in differentiation between objects of the real world and their representation in GIS (i.e., computer). Since classical set theory is used in conventional GIS software systems to model uncertain real world, the natural ...
