vartun geothermal region (vgr) is located in west central part of iran, 300 km in the southeast of tehran. vgr area is 277 km2and there are some geothermal surface manifestations such as warm springs and travertine deposits. there are three warm springs which their temperature varies from 35.3 to 43.1 °c. their ph is a little bit acidic and is about 6.1-6.2. based on geothermometery studies var...

Automatic Grid resource discovery and brokerage shields the Grid middleware complexities from the Grid users and leads towards an invisible but simple and robust Grid. Realizing this vision requires a machine understandable resource description and powerful correlation 1 mechanism. Semantic technologies like ontologies provide vocabularies with explicitly defined, unambiguously understandable a...

We define and study a resource-allocation game, arising in Media on Demand (MoD) systems where users correspond to self-interested players who choose a MoD server. A server provides both storage and broadcasting needs. Accordingly, the user’s cost function encompasses both positive and negative congestion effects. A system in our model consists of m identical servers and n users. Each user is a...

In this abstract we emphasize the role of a semantic structure called resource graph in order to study the provability in some resource-sensitive logics, like the Bunched Implications Logic (BI) or the Non-commutative Logic (NL). Such a semantic structure is appropriate for capturing the particular interactions between different kinds of connectives (additives and multiplicatives in BI, commuta...

Appropriate abstractions, mechanisms, and policies for resource allocation is quickly emerging as the fundamental problem facing emerging computation and communication environments such as PlanetLab and the Grid. This paper explores the utility of one simple abstraction for global resource allocation with a number of appealing properties: a centralized auction that collects user descriptions of...

Research in multiagent systems is advancing and one can predict its future widespread implementation in real-world systems. One needs however to acknowledge that the agents evolving in the real world have limited access to resources. They have to seek after resource objectives and compete for those resources. We introduce a class of resource games where resources and preferences are described w...

1. Analyses based on utilization distributions (UDs) have been ubiquitous in animal space use studies, largely because they are computationally straightforward and relatively easy to employ. Conventional applications of resource utilization functions (RUFs) suggest that estimates of UDs can be used as response variables in a regression involving spatial covariates of interest. 2. It has been cl...

this article is arranged based on a research plan which its goals is evaluation of the possibility of applying flexible human resource structure in industrial organizations. in this research, applying conditions of just in time (j.i.t) and flexible manufacturing systems (f.m.s) have brought up as a pioneer flexible movements in industrial units and based on based two phenomenon, the nescessity ...
