wild goat (capra aegagrus) is one of the most prominent mountain mammals dispersed in many habitats in iran. however, few studies on the relationship between this species and its habitat have been conducted. this species is recognized as one of the main food source for highly endangered species such as cheetah and leopard. in this study which lasted from fall 2009 through summer 2011, seasonal ...

Firstly, the paper presents the concepts of USDI and spatial metadata. Then after analyzing the existing spatial metadata managing systems, a mode of building distributed spatial metadata system is described and proposed according to the requirements of construction of USDI and our engineering practices. The system adopts XML as descriptions of metadata standard and three-layer B/S structure as...

The leading policy to conserve forest is protected areas (PAs). Yet, PAs are not a single tool: land users and uses vary by PA type; and public PA strategies vary in the extent of each type and in the determinants of impact for each type, i.e. siting and internal deforestation. Further, across regions and time, strategies respond to pressures (deforestation and political). We estimate deforesta...

‘Computer-Supported Cooperative Work’ (CSCW) is a young, interdisciplinary research area considering applications with strong demands on multiple fields of computer technology, e.g., distributed systems and networks or multi-media systems. In this paper, we will be focusing on the information-sharing and the corresponding activity-control aspect. Here, the conventional transaction concept of da...

Organizations increasingly use projects to achieve business objectives but report that results often fall short of goals. A number of formal standards for managing projects have been developed intending to improve such project outcomes. However, research examining this assumption is scarce and has yielded mixed results. This paper presents the development and use of a set of metrics for assessi...

fuzzy logic has a high potential for managing the uncertainty sources associated with the medical expert systems. application of fuzzy inference model has been widely concentrated for managing uncertainties in computer based practices of medicine. this paper has proposed two fuzzy expert systems for prognosis of the heart disease based on: 1) mamdani inference model, and 2) sugeno inference mod...
