Climate, topography, soil and land use data which closely associated with the distribution of maize (Zea mays L.) has been collected and collated to identify the suitable areas for maize on condition of nature and using the technique of whole plastic-film Mulching on Double Ridges in China, the database of these factors have been created in the current article. The weights of these factors, cri...

To date, most work regarding the formal analysis ofaccess control schemes has focused on quantifying and comparingthe expressive power of a set of schemes. Although expressivepower is important, it is a property that exists in an absolutesense, detached from the application-specific context within whichan access control scheme will ultimately be deployed. In thispaper, b...

This article compares two fuzzy approaches to land suitability evaluations, Analytical Hierarchy Process (AHP) and Ideal Point. The methods were evaluated using a case study which models the opportunities for wheat production under irrigation conditions in the north-western region of Jeffara Plain, Libya. A number of relevant soil and landscape criteria were identified through a review of the l...

Land suitability analysis is employed to evaluate the appropriateness of land for a particular purpose whilst integrating both qualitative and quantitative inputs, which can be continuous in nature. However, in agricultural modelling there is often a disregard of this contiguous aspect. Therefore, some parametric procedures for suitability analysis compartmentalise units into defined membership...

We present a view of a context hypothesization process performed using the probabilistic knowledge of a domain. We outline the underlying asumptions and requirements for a focussed construction of interesting hypothetical contexts for probabilistic reasoning. The formalism presented seeks to construct consistent, minimal, and desirable probabilistic contexts by selecting suitable domain attribu...

The goal of this analysis was to explore a GIS-based technique to assess the potentially suitable locations for monitoring air toxics pollutants emitted at landfills. Several map layers such as landfill activity, population density, and distances from other emission sources were incorporated into three different suitability modeling scenarios. The ArcGIS Spatial Analyst tool was used to perform...

This study aimed to analyse and evaluate the land suitability for certain fruit trees in Thuy Bang commune using GIS techniques in combination with a multi-criteria approach. At first, the databases for GIS analyses had to be developed. The data were obtained through scientific literature review, expert opinions, interviews, and professional officers. The suitability assessment in the studied a...

A fundamental step in conserving biodiversity is identification of quality habitat needed to sustain populations of target species. We used coarse scale environmental features (soil water holding capacity, soil texture, slope, elevation, and proximity to drainage channels) to predict habitat suitability for four species of desert amphibians in Big Bend National Park, USA: Scaphiopus couchii, Bu...
