In the remainder, we call such a variety a convex symplectic variety. A convex symplectic variety has been studied in [K-V], [Ka 1] and [G-K]. One of main difficulties we meet is the fact that tangent objects TX and T 1 Y are not finite dimensional, since Y may possibly have non-isolated singularities; hence the usual deformation theory does not work well. Instead, in [K-V], [G-K], they introdu...

To learn about users’ experiences in using network applications, we present a lightweight, non-intrusive, and efficient framework called OneClick. The framework only requires a subject to click a dedicated key whenever he/she feels dissatisfied with the quality of application in use. By aligning the collected traffic trace and the click process, we apply Poisson regression to analyze the relati...

Background: Fatal road accidents are among the most important causes of mortality in the world; Iran has one of the world’s highest accident fatality rates. Therefore, it is important to have efficient pre-hospital emergency services. Objectives: The main aim of this study was to assess the road emergency sites (RECs) in Iran. Materials and Methods: Provincial data were used for this purpose. C...
