I In this paper, a new filter is designed to enhance medial-axis of tubular structures. Based on a multi-scale method and using eigenvectors of Hessian matrix, the distance of a point to the edges of the tube is found. To do this, a hypothetical line with a deliberate direction is passed through the point which cuts the tube at its edges. For points which are located on the medial-axis, this di...

به منظور شبیه سازی انتقال باکتری، رشد و متابولیتهای میکروبی تولید شده در محیط متخلخل و همچنین اثر آن در میزان ازدیاد برداشت نفت به روش میکروبی یک مدل دو بعدی، چهار فازی تهیه شده است. در فرآیند ازدیاد برداشت نفت به روش میکروبی هنگام رشد باکتری، چندین نوع متابولیت مانند الکل، سورفکتانت، گاز و پلیمر تولید می شوند، که باعث افزایش راندمان تولید نفت می شوند. مکانیسم های میکربی ازدیاد برداشت نفت در ای...

The present study aims to analyze the existing indoor environmental conditions of Firozabad City along with its impact on people’s health by going through the correlative index of indoor environment’s determinant and different diseases, faced by the people. In order to measure spatial disparities, the statistical technique, i.e. the standard score additive model (Z- score), has been applied to ...
