A Stress Analysis of Pipe Flange Connections
The use of pipe flange connections is standardized in the codes of JIS, ASME, DIN and so on. However, these codes are almost entirely dependent on experience, and subsequently some problems concerning pipe flange connections have been encountered. In the present paper, the distribution of contact stresses which governs the sealing performance is analyzed as a three-body contact problem, using a...
متن کاملReview of GPR Rebar Detection
The background and current state of the art of ground penetrating radar testing of rebar in concrete is briefly reviewed. This encompasses developments of Polarization in rebar detection, diameter detection, corrosion detection,neural network and other automatic method in rebar detection.
متن کاملAutomatic Multiple Landmine Detection Using Gpr
The land mine crisis is all over frightening since there are presently 500 million unexploded, buried mines in about 70 countries. Governments are noticing this situation seriously since land mines are claiming the limbs and lives of civilians’ very day. A multiple of landmine extraction from the data which are obtained from the Ground Penetrating Radar (GPR). Traditional algorithms targets on ...
متن کاملDetection of linear objects in GPR data
In this paper, we propose a semi-automatic approach to the detection of linear scattering objects in geo-radar data sets, based on the 3D radon transform. The method that we propose is iterative, as each detected object is removed from the data set before the next iteration, in order to avoid mutual interference or masking. In addition, the algorithm is able to further analyze the data set in a...
متن کاملGPR Environmental-Based Landmine Automatic Detection
According to the United Nations, as of the year 2000 there were 70 million landmines planted in a third of the world’s nations affecting global causality rate of up to 20,000/year, (Anderson, 2002). That is why landmine detection has attracted much attention by many research teams around the world during the last two decades; among them is our research team in Nagoya University. Anti-personnel ...
