In this paper, a customized Fuzzy Inference System is presented to classify the corrosion and distinguish it from the geometric defects or normal state of the steel pipes used in gas/petroleum industry. The presented strategy is hybrid in the sense…
The control and managing of pipelines have been assuming a major importance for all kinds of fluids to be conveyed through. When the fluid is like oil, harmful liquid and/or water for human beings necessity, the monitoring of pipelines becomes…
Leak detection of oil pipelines is an important issue for safe operation of pipelines, reducing oil loss and environmental pollution. A new approach based on principal component analysis (PCA) method to detect leaks of oil pipelines is proposed in…
This paper introduces a practical teleoperated manipulator under nuclear radioactive environments. The system, called RoboSource herein, is designed to perform the leak detection of sealed gamma and neutron radioactive sources used for oil well…
Nowadays, the new trend of global economy has driven the business strategy from the local to the global supply chain optimization. The comprehensive logistics solutions are critical to integrate supply chain management in the global landscape. We…
This paper describes an augmented reality system that incorporates a real-time dense stereo vision system. Analysis of range and intensity data is used to perform two functions: 1) 3D detection and tracking of the user's fingertip or a pen to provide…
Recently developed optical inspection tools provide images from the inside of natural gas pipelines to monitor pipeline integrity. The vast amount of data generated prohibits human inspection of the resulting images. We designed an image processing…
Pinus armandi franch is a special local plant in China and its seed oil is a nice resource of linoleic acid (LA) with a content of 63% of the total fatty acid. LA is an essential fatty acid and it exerts a variety of physiological functions. The…
Objective: To find the antitumor compounds from Rabdosia Serra (Maxim) Hara, phytochemical isolation procedures were performed by bioassay-guided fractionation. Methods: The ethanol extract of Rabdosia serra (Maxim) Hara was fractionated by organic…
