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...

The benefits of deploying next-generation Internet broadband “last mile” networks (to the home) are widely recognized. It’s deployment would allow far improved delivery of education, (in home) healthcare and telecommuting facilities as well as new opportunities for entertainment. What is less clear to many is how to realize the network, given that private industry needs to fund and build it. Th...

Accessing computer resources from off campus has been a continuing problem for both students and faculty, and this problem has been exacerbated by the growth of our graduate program. A multi-layered remote authentication system has been created for use by students and faculty providing the ability to telecommute and gain remote access to these resources. Security concerns have also been address...

Knowledge Management is a recent development in business, allowing for an organization to increase its competitive advantage. Managing the knowledge worker of today is much different from managing the rank and file employees of the past. It is important to understand the knowledge workers, their traits and personalities, before learning how to best manage them. This paper discusses these issues...
