the consideration of tehran metropolis and its soundings areas has been the first one of recent challenges in iran’s spatial planning which made it possible to develop the concepts such metropolitan region and conurbation. however, it is obvious that there appears to be a much more proper structure due to neo-regionalism and globalization in order to understanding of dynamic nature of tehran an...

This paper analyzes the Gibbs sampler applied to a standard variance component model, and considers the question of how many iterations are required for convergence. It is proved that for K location parameters, with J observations each, the number of iterations required for convergence (for large K and J) is a constant times ( 1 + logK log J ) . This is one of the first rigorous, a priori resul...

In the future, Web services and software agents will coexist in the Business Process Management solution space. In our vision, agents will have symbiotic relationships with Web services, harnessing them as externally defined agent behaviors. In this paper we detail the development of a demonstration system that transparently integrates agent services into BPEL4WS defined workflows. The developm...

It is proved that for K location parameters, with J observations each, the number of iterations required for convergence (for large K and J) is a constant times 1 + log K log J.

Repeatable, quantitative assessment of intervertebral disc pathology requires accurate localization and labeling of the lumbar region discs. To that end, we propose a two-level probabilistic model for such disc localization and labeling. Our model integrates both pixel-level information, such as appearance, and object-level information, such as relative location. Utilizing both levels of inform...

What are we in the Modeling & Simulation (M&S;)community to do with the volumes of ‘human terrain’ datanow being published by the military and others indatabases of the demographics and needs/values/norms ofpopulations of interest? This paper suggests that the M&S;community would be remiss if it did not rise to thischallenge and suggest next steps for the use of this human...

 The complexity of software applications continues to increase, and the user’s aversion to software defects is greater than ever, so our functional testing has to become more and more effective at detecting bugs;  The cost and time of testing is already a major proportion of many projects (sometimes exceeding the costs of development), so there is a strong push to investigate methods like MBT...

abstract by using cross-section data which gathered through a survey research in mashhad ,contingent valuation approach and tobit model this study tries to determine economical value of air pollution and effective factors on wtp. based on contingent valuation approach, air pollution total value of airpollution in high-polluted region equals 7134146560 rials per month and in middle-polluted regi...

This paper describes a method for cast shadow removal from obliquely illuminated images of faces. The method draws on a statistical model of surface normal directions. The model is fitted to shadowed facial images using robust statistics and constraints provided by shape-from-shading. Regions associated with poor fit residuals are associated with shadow regions. We illustrate the method on the ...
