Hydraulic conductivity is an essential parameter for groundwater investigation and management. A simple technique determining the hydraulic of aquifers slug test, which consists measuring water level in a well after sudden removal or injection small amount water. The interpretation test based on geometry-dependent shape factor, various empirical relationships approximate solutions have been pro...

In this paper, we propose a deep-learning based approach for estimating local 3D shape properties in point clouds. In contrast to the majority of prior techniques that concentrate on global or mid-level attributes, e.g., for shape classification or semantic labeling, we suggest a patch-based learning method, in which a series of local patches at multiple scales around each point is encoded in a...

tuberculosis is an important opportunistic disease among hiv- infected persons worldwide; from march 1999 to feburery 2001 we had seventeen patients with hiv-infection and tuberculosis. here we are presenting the clinical manifestations, diagnosis, treatment and outcome of them. all of them were male, 11 patients had pulmonary and 5 patients had extrapulmonary (pleural effusion 1, hepatic granu...

Image segmentation is an important stage in any image processing process. Regions of interest in the image are extracted from the image and are used to interpret the information in the image. This study investigates the image segmentation of X-ray images and aims at separating the bone from the rest of the X-ray. Basic edge detection techniques and Active Shape Models are the image segmentation...

In this paper we present a method for constraining the deformations of Snakes (Active Contour Models) when segmenting a known class of objects. The method we propose is similar to both Active Shape Models (ASM) but without the landmark identification and correspondence requirement, and to Active Contour Models (ACM), but armed with a priori information about shape variation. Rather than represe...
